# SQLAQ There are several states to deal with at this point
# A) the datatable exists but a feed has been added
# B) the datatable doesn't exist and needs to be created
# C) the datatable needs to be updated for more or less feeds
# D) the datatable_exists flag is incorrect because all edge cases
# haven't been handled yet.
#
# My logic is that once Trump is more functional, I'll be able to
# eliminate this hacky solution. But, SQLAlchemy might have
# a more elegant answer. A check, of somekind prior to deletion?
# if not self.datatable_exists:
# self._init_datatable() #older version of _init_datatable
# delete(self.datatable).execute()
# self._init_datatable() #older version of _init_datatable
# Is this the best way to check?
# if engine.dialect.has_table(session.connection(), self.name):
# delete(self.datatable).execute()
