Re: Django request.GET and jQuery Datatables

OK, thanks! I won't use it for this specific case, but I'm sure it will be extremely helpful in the future. The logic you've shown can be applied in other different contexts.

Yep but happening inside the form itself. Eg:

class MyForm(Form):
  def __init__(self, *args, **kwargs):
    data =kwargs.get('data')
    if data:
      new_data = QueryDict(mutable=True)
      new_data[...] = ....
      ...
      kwargs['data'] = new_data
    super(MyForm, self).__init__(*args, **kwargs)

view:

form = MyForm(data=request.POST)

Then, anywhere you use the form it has the logic to process the data
correctly without polluting the view.

Cheers
