hi, i'm trying to implement a dynamic table in django. every column of the table is coded as a python object and i want to pass a list of these objects to the template as the context.
every object has a method which runs a rather expensive query on the database and returns a list which can be empty. my problem is that when this list is empty i want to branch in the template, and display some sort of message, instead of the usual 'for' loop which would display the returned list. since i can't assign the returned list to a variable i have to check the method's return value first with an 'if' tag than run the query again for the 'for' loop. this doubles the load on the db what i don't like, not to mention that the two queries may return different lists. am i missing something? do i follow a bad pattern? why i can't extend the context from inside a template? thanks bmt --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
