How to fix Direct assignment to the forward side of a many-to-many set is prohibited. Use emails_for_help.set() instead with Python Django?
To fix Direct assignment to the forward side of a many-to-many set is prohibited. Use emails_for_help.set() instead with Python Django, we should add our many to many relations objects after the original object is created.
For instance, we write
class SetUser(FormView):
template_name="templates/set_up_user.html"
form_class = Set_User_Form
success_url = '/thanks/'
def form_valid(self, form):
org = form.cleaned_data.get('organization')
emails = form.cleaned_data.get("share_email_with")
users = User.objects.filter(email__in=emails)
instance = SetupUser.objects.create(organization=org)
for user in users:
instance.emails_for_help.add(user)
return redirect("/")
to create the user object with
instance = SetupUser.objects.create(organization=org)
And then we add the user into the emails_for_help many to many field by writing
for user in users:
instance.emails_for_help.add(user)
Conclusion
To fix Direct assignment to the forward side of a many-to-many set is prohibited. Use emails_for_help.set() instead with Python Django, we should add our many to many relations objects after the original object is created.
