Django 2 models 1 form

Question

So, I\'m still a total noob at Django and I was wondering how to do the following:

So lets say that I have something like the below code:

class UserP         


        

Answer 1

This kind of problem is what inline formsets are designed for.

Answer 2

The way I did it was to create a form based on the first model, and then to create a form based on the second model that inherits the first form. Meaning:

class UserProfileForm(ModelForm): ...

class UserProfileOtherForm(UserProfileForm): ...

And pass the UserProfileOtherForm to form template. It worked for me. Not sure if there is a simpler approach.

Answer 3

You can create two separate ModelForm classes. But in your view, you have to add a prefix to their instances.

def viewname(request):
    if request.method == 'POST':
        form1 = forms.YourForm(request.POST, prefix="form1")
        form2 = forms.YourOtherForm(request.POST, prefix="form2")
        if form1.is_valid() and form2.is_valid():
            # process valid forms
    else:
        form1 = forms.YourForm(prefix="form1")
        form2 = forms.YourOtherForm(prefix="form2")

    ....

Using a prefix ensures that fields with similar names are not mixed up.
