How do I do a if a in list_b test in Django 0.96 Templates?

I'm having a list of checkboxes and a variable containing a list of corresponding values from a previous submit of the checkboxes.

Now I want to set all checkboxes in the list to checked="checked" and I usually use a "if a in listb" test for this. But this doesn't seem to be possible in Django 0.96 templates?

Answer 1

It's not possible in any version of Django templates. You need to write a custom template tag, or use something like the smart-if tag.

However I suspect you should be doing this in the view, by using Django's forms framework.

Answer 2

You could also just use jQuery or a similar Javascript library which is more suited for DOM scripting than Django. Also, it should makes your views.py considerably less bloated and thus easier to read and maintain.
