Hello All,
I had created multiModelForm in Django, I can view, and save data, I
don't know how to Update data into the database. I want if user id exists
in database then update else insert.exist in the database then update else
insert.
This Code is working for me but I don't know how to update existing data?
# forms.py
from django import forms
from authtools.forms import UserCreationForm
from betterforms.multiform import MultiModelForm
from .models import UserProfile
class UserProfileForm(forms.ModelForm):
class Meta:
fields = ('favorite_color',)
class UserCreationMultiForm(MultiModelForm):
form_classes = {
'user': UserCreationForm,
'profile': UserProfileForm,
}
# views.py
from django.views.generic import CreateView
from django.core.urlresolvers import reverse_lazy
from django.shortcuts import redirect
from .forms import UserCreationMultiForm
class UserSignupView(CreateView):
form_class = UserCreationMultiForm
success_url = reverse_lazy('home')
def form_valid(self, form):
# Save the user first, because the profile needs a user before it
# can be saved.
user = form['user'].save()
profile = form['profile'].save(commit=False)
profile.user = user
profile.save()
return redirect(self.get_success_url())
