No. Usually, you would try to keep all of your filtering in the managers module, and then you would be able to limit your refactoring of filters in that file. You could try using *args and **kwargs syntax, but that would make it difficult to maintain. I suppose you could functions in SQLAlchemy, and if you really wanted functions in Django, you could make them yourself.
I actually like the Django syntax. It's very easy to follow. You can also use the __ for related fields.

I’m pretty new to Django. I have just learnt that could filter a query set this way: Questions.objects.filter(question_text__contains=‘what’) This kind of scares me a little because the filter “contains” is actually part of the field name. And I guess there are other operators appended to a field with the same __operation pattern. Wouldn’t this make refactoring tricky? Even renaming the field name has to be done carefully. In my mind, this feels messy. Is there an alternative to doing this? Something like: Questions.objects.filter(question_text.contains=‘what’) Or using “contains” as a function? Basically, can I do the same thing without adding “magic strings” to field names? -- You received this message because you are subscribed to the Google Groups "Django users" group.
