need to find out if someone is an orphan when I have mother_alive and father_alive fields in the database

[eil...@themaii.org]

Hi,

I need to find out if someone is an orphan when I have mother_alive and father_alive fields in the database. Stepfathers, and stepmothers etc aren't counted when determining if someone is an orphan, only their birth mother, and birth father.

I tried 

  if form['orphaned'].data == True:

             q = context['child_filter'].filter(Q(request.POST.get('mother_alive') == 0 and request.POST.get('father_alive') == 0))

but I got an error on it.

does anyone know what I did wrong?

Hi Eileen,

What is the error message?

By the way, one way to improve your code readability would be to use form.is_valid() :

For instance:

new_data = form.is_valid()

Hope this helps,

Etienne

Hi.

Your code is incomplete and actual error (whole traceback is missing)

Also you're trying to mix usage of form and reading post data directly. You should only use form to deal with user input. See https://docs.djangoproject.com/en/2.0/topics/forms/  for more information.

Finally with Q queries you don't use and-operator. See details at 

https://docs.djangoproject.com/en/2.0/topics/db/queries/#complex-lookups-with-q-objects
