Django form with two submit buttons . . . one requires fields and one doesn't

Question

I think this should be a fairly straightforward question . . . I have ONE Django form with TWO different submit buttons. The first submit button is just for SAVING to the database whatever values are typed in to the form fields (so the user can come back and finish the form later if they want). I want the form fields to NOT be required when this first submit button is clicked. When the user clicks the second submit button, though, all fields should be required. Is there a way to do this? Or do I just have to duplicate the form once for each submit button?

Answer 1

The answer above works, but I liked this way better: Changing required field in form based on condition in views (Django)

I have two buttons:

<!-- simply saves the values - all fields aren't required unless the user is posting the venue -->
<input type="submit" name="mainForm" value="Save">

<!-- post the values and save them to the database - fields ARE required-->
<input type="submit" name="postVenue" value="Post Venue">

I make all form fields required=False by default and then have this in my view:

if 'postVenue' in request.POST:
    form = NewVenueForm(request.POST)
    form.fields['title'].required = True
    form.fields['category'].required = True
    # do this for every form field
                          
elif 'mainForm' in request.POST:     
    form = NewVenueForm(request.POST)

Thanks everyone!!
