Why do we need `*args` in decorator? : <pre><code>def pass_thru(func_to_decorate):
def new_func(*args, **kwargs): #1
print("Function has been decorated. Congratulations.")
# Do whatever else you want here
return func_to_decorate(*args, **kwargs) #2
return new_func
def print_args(*args):
for arg in args:
print(arg)
a = pass_thru(print_args)
a(1,2,3)
>> Function has been decorated. Congratulations.
1
2
3
</code></pre>
<p>I understand that <code>*args</code> is used in #1 since it is a function declaration. But why is it necessary to write <code>*args</code> in #2 even if it not a function declaration? </p>

how to open email app and display text in label with single click : i have a table with accept link in the first column when the it is clicked then have another column with a label with pending. therefore when thee accept is clicked the **pending** is updated to **accepted**
this line was my original code, when the accept is pressed it is displayed.
<a href="tea_appview.php?app_id=<?php echo $row['app_id'] . "&" . "state=accept";?>" class="accept">accept</a>
--------------------------------------
then i added this line so that i can also send a mail. what happens here is when the accept llink is clicked the default mail app opens but the label does not get updated from pending to accepted
<a href='mailto:".$email."?Subject=PARENT%20INQUERY' "tea_appview.php?app_id=<?php echo $row['app_id'] . "&" . "state=accept";?>" class="accept">accept</a>

What would be the correct view that needs to be created to meet the requirements? : I have a set of tables given to me and a specific business requirement that needs to be solved by creating a View in SQL. I am having trouble with understanding joins and stuff etc. I have made an attempt, but I think I am completely wrong and need some help.
The tables are as follows:
tblClients (ClientID, ClientName, ClientAddress, ClientCity, ClientProvince, ClientPostalCode, ClientPhone, ClientEmail)
tblVehicle (VehicleID, VehicleMake, VehicleModel, VehicleYear, ClientID)
tblEmployees (EmployeeID, EmployeeFirstName, EmployeeLastName, EmployeeAddress, EmployeeCity, EmployeeProvince, EmployeePostalCode, EmployeePhone, EmployeeEmail)
tblWorkOrders (OrderID, VehicleID, EmployeeID, WorkDescription, PartsCost, LabourCost, IssueDate, CompletionDate)
________________________________________________________________________________
and the Requirement is this:
A web application is being considered that will allow customers with accounts – using their email address as a login – to view their invoice / work order history with the garage.
Using SQL, create a view that will allow a customer to see work done on each of their cars, including the work description, costs and dates but not which employee completed the work.
________________________________________________________________________________
WHAT I HAVE SO FAR:
CREATE VIEW WORK_HISTORY AS
SELECT WORKDESCRIPTION, PARTSCOST,LABOURCOST, ISSUEDATE, COMPLETIONDATE
FROM TBLWORKORDERS LEFT OUTER JOIN TBLVEHICLE
ON TBLWORKORDERS.VEHICLEID = TBLVEHICLE.VEHICLEID
I dont think its too complicated, but I am new to SQL, so all your help and criticism will be appreciated. If you need anything else please let me know and I will edit as necessary. Thank you!

<p>while I run <strong>cordova requirements</strong>, it says android target is not intalled
and set the ANDROID_HOME environment variable</p>
<pre><code>I:\CordovaProject\hello>cordova requirements
Requirements check results for android:
Java JDK: installed 1.8.0
Android SDK: installed true

</code></pre>
<p>as you can see in the image 1, when I echo ANDROID_HOME it is set to proper location. I am not able to resolve this error. kindly help me with this </p>
<p>path has these : %ANDROID_HOME%\tools;%ANDROID_HOME%\platform-tools</p>
<p>I have downloaded android-25 in android studio </p>
<p>and project properties file has android target set to : android-25 both in
I:\CordovaProject\hello\platforms\android\CordovaLib\project.properties<br>

Why Build is needed? : <p>I am highly confused as why Build is needed in a java project.</p>
<p>I am new to Java. I have created a Java project which creates volume file.
I have run this code on my machine and created a JAR file and batch file which executes this JAR.
Now who ever needs it, I hand over the JAR file along with .bat file and it is good to go.</p>
<p>Where some one asks me source code, I give them via SVN.</p>
<p>In this process I couldn't relate what BUILD means and where it is actually needed? And why we need build tool like Maven (I know what maven is but can't relate)
I can easily share my JAR files and libraries with anyone who needs it.</p>

Unable to filter messages by recipient in Microsoft Graph Api. One or more invalid nodes : <p>I am trying to get a list of messages that are filtered by recipient from Microsoft Graph API. The url I am using for the request is:</p>
<p><code>https://graph.microsoft.com/beta/me/messages?$filter=toRecipients/any(r: r/emailAddress/address eq '[Email Address]')</code></p>
<p>But I am getting this is the response:</p>
<pre><code>{

"code": "ErrorInvalidUrlQueryFilter",
"message": "The query filter contains one or more invalid nodes.",

"date": "2016-09-28T16:58:34"
}
}
}
</code></pre>
<p>A successful request should look like this (with a lot more data that I have omitted).</p>
<pre><code>{
"@odata.context": "https://graph.microsoft.com/beta/$metadata#users('99999999-9999-9999-9999-999999999999')/messages",

{
"emailAddress": {
"name": "[Name]",
"address": "[Email Address]"
}
}
],
}
]
}
</code></pre>
<p>The request works if I remove the filter, and I am able to perform requests with simpler filters.</p>
<p>Is there a problem with my URL, or is there another way to make the request?</p>

Show only selected controllers in swagger-swashbuckle UI : <p>I am currently using swagger in my project and i have more than 100 controllers there. I guess due to the large number of controller, swagger UI documentation page takes more than 5 min to load its controller. Is it possible to select specific controllers at the UI page and load options for them only?
Or else there are other methods to load UI page faster?
Help me!</p>

C# Coding Best Practice : <p>I'm currently doing work which requires me to convert VB.Net code to C#.
I've been using the "Builder Pattern" primarily and this has me converting many functions that are one single call of a function ie. SomeFunction(var1,var2,var3) into:</p>
<pre><code>Dim Director As New SomeDirector
With Director
.SomeProperty = SomeValue
.SomeProperty2 = SomeValue2
End With
</code></pre>
<p>My concern is that this creates 5-6 lines of code rather than one single line. Is there a way for me to do this in a more concise way or is it better to have the 5-6 lines of code?</p>
<p>Thanks!</p>

How do I transpose a tibble() in R : <p>In R the <code>t()</code> function is really meant for matrices. When I try to transpose my tibble with <code>t()</code> I end up with a matrix. A matrix can't be made into a tibble with <code>tibble()</code>. I end up spending time storing column names as variables and attaching them as I try to re-make a transposed version of my tibble. </p>
<p>Question: What is the simplest way to transpose a tibble where the first column should become the column names of the new tibble and the old column names become the first column of my new tibble. </p>

Python code - missunderstanding : guys
a few days ago I bought a book called "Python for kids" (for dummies).
On page 47 there is an example of a simple code and its result as follows:
a = 2
while a < 10:
a = a + 1
print (a)
resulting in:
3
4
5
6
7
8
9
10
...............................................
I think this result is incorrect, because:
- There is no 2 printed out as declared in the first line of the code
- There is though 10 printed out (10 is equal 10, not less than 10)
Even if I make the 'while' condition: a <= 10, it prints out the numbers 3 to 11 which is again incorrect.
What I think should be the correct code is as follows:
a = 2
while a < 10:
print (a)
a = a + 1
resulting in:
2
3
4
5
6
7
8
9
...............................................
Now this is what I was expecting from the code. I played a little bit with the code and interestingly enough Python allows some strange arrangements which are executable without errors yet totally incorrect! For example:
a = 2
while a < 30:
a = a + 5
print (a)
result is only the number:
32
(incorrect it seems to be)
If I indent |print (a)| (by 4 spaces) I get:
7
12
17
22
27
32
Incorrect again. Can you explain to me why all this happens like that?

How do I initialize a composed struct in Go? : <p>Let's say I have a struct with another struct embedded in it.</p>
<pre><code>type Base struct {
ID string
}
type Child struct {
Base
a int
b int
}
</code></pre>
<p>When I go to initialize <code>Child</code>, I can't initialize the <code>ID</code> field directly.</p>
<pre><code>// unknown field 'ID' in struct literal of type Child
child := Child{ ID: id, a: a, b: b }
</code></pre>
<p>I instead have to initialize the ID field separately.</p>
<pre><code>child := Child{ a: 23, b: 42 }
child.ID = "foo"
</code></pre>
<p>This would seem to violate encapsulation. The user of Child has to know there's something different about the ID field. If I later moved a public field into an embedded struct, that might break initialization.</p>
<p>I could write a <code>NewFoo()</code> method for every struct and hope everyone uses that, but <strong><em>is there a way to use the struct literal safely with embedded structs that doesn't reveal some of the fields are embedded?</em></strong> Or am I applying the wrong pattern here?</p>

Realm accessed from incorrect thread - again : <p>I noticed many problems with accessing realm object, and I thought that my solution would be solving that.</p>
<p>So I have written simple helping method like this:</p>
<pre><code>public func write(completion: @escaping (Realm) -> ()) {
DispatchQueue(label: "realm").async {
if let realm = try? Realm() {
try? realm.write {
completion(realm)
}
}
}
}

<p>I thought that completion block will be fine, because everytime I write object or update it, I use this method above. </p>
<p>Unfortunately I'm getting error:</p>

In Python, how do I create and array from words from multiple lists, with word occurrences : <p>I have a JSON file that has multiple objects with a text field:</p>
<pre><code>{
"messages":
[
{"timestamp": "123456789", "timestampIso": "2019-06-26 09:51:00", "agentId": "2001-100001", "skillId": "2001-20000", "agentText": "That customer was great"},
{"timestamp": "123456789", "timestampIso": "2019-06-26 09:55:00", "agentId": "2001-100001", "skillId": "2001-20001", "agentText": "That customer was stupid\nI hope they don't phone back"},
{"timestamp": "123456789", "timestampIso": "2019-06-26 09:57:00", "agentId": "2001-100001", "skillId": "2001-20002", "agentText": "Line number 3"},
{"timestamp": "123456789", "timestampIso": "2019-06-26 09:59:00", "agentId": "2001-100001", "skillId": "2001-20003", "agentText": ""}
]
}
</code></pre>
<p>I'm only interested in the 'agentText' field.</p>
<p>I basically need to strip out every word in the agentText field and do a count of the occurrences of the word.</p>
<p>So my python code:</p>
<pre><code>import json
with open('20190626-101200-text-messages.json') as f:
data = json.load(f)
for message in data['messages']:
splittext= message['agentText'].strip().replace('\n',' ').replace('\r',' ')
if len(splittext)>0:
splittext2 = splittext.split(' ')
print(splittext2)
</code></pre>
<p>gives me this:</p>
<pre><code>['That', 'customer', 'was', 'great']
['That', 'customer', 'was', 'stupid', 'I', 'hope', 'they', "don't", 'phone', 'back']
['Line', 'number', '3']
</code></pre>
<p>how can I add each word to an array with counts?
so like;</p>
<pre><code>That 2
customer 2
was 2
great 1
..
</code></pre>
<p>and so on?</p>

Why is passing by value (if a copy is needed) recommended in C++11 if a const reference only costs a single copy as well? : <p>I am trying to understand move semantics, rvalue references, <code>std::move</code>, etc. I have been trying to figure out, by searching through various questions on this site, why passing a <code>const std::string &name</code> + <code>_name(name)</code> is less recommended than a <code>std::string name</code> + <code>_name(std::move(name))</code> if a copy is needed.</p>
<p>If I understand correctly, the following requires a single copy (through the constructor) plus a move (from the temporary to the member):</p>
<pre><code>Dog::Dog(std::string name) : _name(std::move(name)) {}
</code></pre>
<p>The alternative (and old-fashioned) way is to pass it by reference and copy it (from the reference to the member):</p>
<pre><code>Dog::Dog(const std::string &name) : _name(name) {}
</code></pre>
<p>If the first method requires a copy and move both, and the second method only requires a single copy, how can the first method be preferred and, in some cases, faster?</p>

<p>This is a very simple app that just does a single <a href="/questions/tagged/pubnub" class="post-tag" title="show questions tagged 'pubnub'" rel="tag">pubnub</a> subscription. There was no attempt at threading. </p>
<p>Per another question I found on SO, I'm using a stringbuilder:</p>
<pre><code> public StringBuilder logtext = new StringBuilder();

<p>Then I wanted to simplify things so I could just call <code>log("this is a log message")</code>:</p>
<pre><code> public void log(string txt)
{
logtext.Append(Environment.NewLine + txt);
txtLog.Text = logtext.ToString();
}
</code></pre>
<p>Like I said, it logs a few strings fine but then it tries to log the following:</p>
<blockquote>
<p>"ConnectStatus: [1,\"Connected\",\"presence\"]"</p>
</blockquote>
<p>that's when it throws the error. Here is the code which is returning that value:</p>
<pre><code>pubnub.Subscribe<string>(
chnl,
DisplayReturnMessage,
DisplayConnectStatusMessage,
DisplayErrorMessage
);
public void DisplayReturnMessage(string result)
{
log(TimeStamp() + " Result: " + result);

<p>Please ignore the fact that <code>TimeStamp()</code> literally returns "H:mm:ss.ffff" right now :)</p>
<p>I was able to manually <code>log("ConnectStatus: [1,\"Connected\",\"presence\"]")</code> and it worked, so I don't think it's a string issue. The threading thing is really throwing me off.</p>

Sending messages to groups in Django Channels 2 : <p>I am completely stuck in that I cannot get group messaging to work with Channels 2! I have followed all tutorials and docs that I could find, but alas I haven't found what the issue seems to be yet. What I am trying to do right now is to have one specific URL that when visited should broadcast a simple message to a group named "events".</p>
<p>First things first, here are the relevant and current settings that I employ in Django:</p>
<pre><code>CHANNEL_LAYERS = {
'default': {
'BACKEND': 'channels_redis.core.RedisChannelLayer',
'CONFIG': {
'hosts': [('localhost', 6379)],
},
}
}
ASGI_APPLICATION = 'backend.routing.application'
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'rest_framework',
'corsheaders',
'channels',
'channels_redis',
'backend.api'
]
</code></pre>
<p>Next, here is my EventConsumer, extending the JsonWebsocketConsumer in a very basic way. All this does is echo back when receiving a message, which works! So, the simple send_json response arrives as it should, it is ONLY group broadcasting that does not work.</p>
<pre><code>class EventConsumer(JsonWebsocketConsumer):
groups = ["events"]
def connect(self):
self.accept()
def disconnect(self, close_code):
print("Closed websocket with code: ", close_code)
self.close()
def receive_json(self, content, **kwargs):
print("Received event: {}\nFrom: {}\nGroups:
{}".format(content,
self.channel_layer,
self.groups))
self.send_json(content)
def event_notification(self, event):
self.send_json(
{
'type': 'test',
'content': event
}
)
</code></pre>
<p>And here is the URL configurations for the URL that I want to trigger the broadcast:</p>
<p>Project urls.py</p>
<pre><code>from backend.events import urls as event_urls
urlpatterns = [
url(r'^events/', include(event_urls))
]
</code></pre>
<p>Events app urls.py</p>
<pre><code>from backend.events.views import alarm
urlpatterns = [
url(r'alarm', alarm)
]
</code></pre>
<p>And finally, the view itself where the group broadcast should take place:</p>
<pre><code>from django.shortcuts import HttpResponse
from channels.layers import get_channel_layer
from asgiref.sync import async_to_sync
def alarm(req):
layer = get_channel_layer()
async_to_sync(layer.group_send)('events', {'type': 'test'})
return HttpResponse('<p>Done</p>')
</code></pre>

How to troubleshoot/resolve "Signal strength query returned error" logs that are appearing in Xcode 10.1/iOS 12.1? : <p>Recently updated to iOS 12.1 (from 12.0), Xcode 10.1 (from 10.0) and seeing a flood of error messages in the Xcode console when debugging on my physical device like the following:</p>
<p><code>[NetworkInfo] Signal strength query returned error: Error Domain=NSPOSIXErrorDomain Code=13 "Permission denied", descriptor: <CTServiceDescriptor 0x28051d700, domain=1, instance=1></code></p>
<p>I get a couple of these logs every couple seconds, the only thing that changes is the hex value for the CTServiceDescriptor. There have been no code changes so I have to assume its related to the iOS or Xcode updates. </p>
<p>As far as I can tell it doesn't appear to have any performance impact, the app is operating as expected and my phone is working (its even updating its signal strength!). I've been unable to find anything helpful/relevant across Stack Overflow, Google, or the Apple Developer forums though I made a similar post to the latter that I'll link here once the post is approved. </p>
<p>Any suggestions/insight into how I could troubleshoot this further or resolve would be greatly appreciated. Thanks!</p>

two trees and a joint table between them : i have three tables, 2 hierarchical and 1 junction between these.
Teams
id idParent
1 null
2 1
3 null
4 null
5 4
Projects
id idParent
1 null
2 null
3 2
4 2
5 null
TeamProjects
idTeam idProject
2 2
3 1
5 5
A project always depend on at least one team, this is what teamprojects is for.
The result i'm trying to achieve : for each of the object (both teams and projects), i want to know what are the ascendant and descendant objects (id concatened)
idObject ascendantTeams descendantTeam ascendantProjects descendantProjects

I am trying to achieve this with a linq to entities query, but i need both CTE (for the recursive part) and (stuff-for-xml) for the concatenation part... and neither translate to linq to entities.
so i'm trying to make a view to help, but i dont manage to write the sql for it either.
how would you resolve this, either with linq to entities or sql ?

rules not work in jQuery validate function : I don't know what's wrong with my code as i am newbie to jQuery validate function,
i want to use `'required'` value `'true'` or `'false'` dynamically for add and edit page separately. i want field `'cate_image'` set to 'not required' in edit page as already have an image which inserted in 'add' page but need to validate only image format using '`accept`'. help me out.
if($("#hidden_cate_id").val() > 0){
var tf = "false";
}else{
var tf = "true";
}
$("#form-addcategory").validate(
{
rules: {
cate_name: { required: true },
cate_image: { required: tf, accept: "image/jpg,image/jpeg,image/png" }
},
messages: {
cate_name: { required: "Category name is required" },
cate_image: { required: "Category image is required" }
},
});
i put `if` condition for edit page if `$("#hidden_cate_id").` exist `tf` value will `false` and only check for `accept` rule. but it doesn't works !

Bootstrap button outline not working : <p>I am pretty new to Bootstrap, and am having a bit of trouble with getting my buttons styled correctly. I want a green(success) colored button, with just an outline as documented on their website <a href="http://v4-alpha.getbootstrap.com/components/buttons/#outline-buttons">here</a>. When I use the code suggested <code><button type="button" class="btn btn-success-outline">Success</button></code>, I get a grey button that has no apparent styling <a href="http://i.stack.imgur.com/vnA46.png">which looks like this</a>...

Problem with declaring a collection of objects : <p>When I run this code i get a Null Reference exception error when I try to add a tag to the tagCollection. I'm pretty it's an issue with how I've declared tagCollection but I'm not sure where I'm going wrong.</p>
<p>The 2 classes setup are to enable me serialize the collection back to a JSON file once I have finished collecting my data.</p>
<pre><code> class TagCollection
{
[JsonProperty("tags")]
public List<Tag> Tags { get; set; }
}
public class Tag
{
[JsonProperty("name")]
public string Name { get; set; }
[JsonProperty("id")]
public string Id { get; set; }
[JsonProperty("value")]
public string Value { get; set; }
}
private TagCollection tagCollection;
private void createCollection(){
tagCollection.Tags.Add(
new Tag { Name = "Test", Id = "tag1", Value = "145" }
);

<p>While we're on cryptography, you should explain how 2 people can share a completely private key while anyone else is listening in on the conversation. That is the basis of all security on the Internet.</p>

Global data with VueJs 2 : <p>Im relatively new with VueJS, and I've got no clue about how to make some data globally available. I would like to save data like API endpoints, user data and some other data that is retrieved from the API somewhere where each component can get to this data.<br>
I know I can just save this with just vanilla Javascript but I suppose there is a way to do this with VueJS. I may be able to use the event bus system to get the data but I don't know how I can implement this system to my needs.</p>

Frameworks for dynamically managing images in-browser in .NET : <p>Let me first explain what I am trying to achieve... I would like to develop a website that offers some product. This product consists of multiple parts (for example, say a car). The user selects different parts and an image is generated dynamically to preview what the product would look like. </p>
<p>I know how to set the website up, manage database connections, and do all of that. My question is simple: Is there an existing framework that would help me to manage the manipulation of the images easily? My intention is to have separate images of each part and to overlay them in a determined fashion to develop the full product. </p>
<p>I think this would be possible with some fancy manipulation of the basic image controls, but I thought I would see if there was anything to make my job easier. I haven't done much with images in .NET so I don't really know what is available to me as of yet. I am experienced with images in C++ and C. </p>
<p>Note: This is only for research purposes, I am not developing this for any client or job. I just want to see how to do it. I am open to using regular .NET or MVC, depending on which would be most helpful for this.</p>
<p>Thank you for any help that you can offer.</p>

R : Add dynamic column name to row in R : <p>Sample Data :</p>
<pre><code>df <- data.frame(ProdCode = c("C1","C2"), ProdName = c("Product 1", "Product 2"), Category = c("Categ 1", "Categ 2"), "Jan-16" = c(3,2), "Apr-16" = c(3,""), "Jul-16" = c(5,2), "Oct-16" = c(5,2))
</code></pre>
<p>The value corresponding each month and product cell is rating for that product. That need to be in Rating column in output dataframe:</p>
<pre><code>> df
ProdCode ProdName Category Jan.16 Apr.16 Jul.16 Oct.16
1 C1 Product 1 Categ 1 3 3 5 5
2 C2 Product 2 Categ 2 2 2 2
</code></pre>
<p>I've above data which is required in below format:</p>
<pre><code>ProdCode Product.Name Category Rating.Date Rating
C1 Product 1 Categ 1 Jan-16 3
C1 Product 1 Categ 1 Apr-16 3
C1 Product 1 Categ 1 Jul-16 5
C1 Product 1 Categ 1 Oct-16 5
C2 Product 2 Categ 2 Jan-16 2
C2 Product 2 Categ 2 Jul-16 2
C2 Product 2 Categ 2 Oct-16 2
</code></pre>
<p>The month column are dynamic and it will increase such as in future as per product it will come as Jan-2017 etc. I could do it by using for loop but that won't worth of using R.</p>

NodeJS Request how to send multipart/form-data POST request : <p>I'm trying to send a POST request to an API with an image in the request. I'm doing this with the request module but everything I try it isn't working. My current code:</p>
<pre><code>const options = {
method: "POST",
url: "https://api.LINK.com/file",
port: 443,
headers: {
"Authorization": "Basic " + auth,
"Content-Type": "multipart/form-data"
},
form : {
"image" : fs.readFileSync("./images/scr1.png")
}
};
request(options, function (err, res, body) {
if(err) console.log(err);
console.log(body);
});
</code></pre>
<p>But request uses <code>Content-Type: application/x-www-form-urlencoded</code> for some reason... How can I fix this?</p>
