<p>Daniel Skinner's project (mentioned above) seems to have been renamed to DMSL. It seems very powerful, emulates HAML but allows you to use python functions, lambdas, comprehensions etc in it's syntax: <a href="https://github.com/dasacc22/dmsl" rel="nofollow">https://github.com/dasacc22/dmsl</a></p>

<p>First of all, the indexes will be from 0 to 4. Programming languages start counting from 0; don't forget that or you will come across an index out of bounds exception. All you need in the for loop is a variable counting from 0 to 4 like so:</p> <pre><code>for x in range(0, 5): </code></pre> <p>Keep in mind that I ...

<p>The easiest way to do this is to use key names for your vote objects, and use Model.get_or_insert. First, come up with a naming scheme for your key names - naming it after the poll is a good idea - and then do a get_or_insert to fetch or create the relevant entity:</p> <pre><code>vote = VoteRecord.get_or_insert(pol...
