How to programmatically set the model when using Django CreateView?

[Robert F.]

I am trying to programmatically set the model for a Django class-based view that inherits from CreateView and displays a form for creating a 'member' object. My problem is that  my template is not displaying the form itself. Note that I override the 'get' method to determine what model the view should use. The template page renders and I see the submit button but when I view the page's source code, the form is missing. Here's my code:

    # urls.py

    path('profile/create/', views.ProfileCreate.as_view(), name='profile-create'),

    # views.py

    class ProfileCreate(CreateView):

        model = None

        template_name = None

        def get(self, request, *args, **kwargs):

            member = Member.objects.get(user=request.user)

            if member.is_couple:

                self.model = ProfileCouple

                self.template_name = 'account/profile_couple_create.html'

                self.fields = ['person1_name', 'person2_name',

                               'person1_dob', 'person2_dob']

            else:

                self.model = ProfileSingle

                self.template_name = 'account/profile_single_create.html'

                self.fields = ['person1_name', 'person1_dob']

            context = {}

            return render(request, self.template_name, context)

    # models.py

    class ProfileSingle(models.Model):

        user = models.OneToOneField(User, on_delete=models.CASCADE, null=True)

        person1_name = models.CharField(_("Name"), max_length=50)

        person1_dob = models.DateField()

        def __str__(self):

            return self.user.username

    class ProfileCouple(models.Model):

        user = models.OneToOneField(User, on_delete=models.CASCADE, null=True)

        person1_name = models.CharField(_("Name 1"), max_length=50)

        person1_dob = models.DateField()

        person2_name = models.CharField(_("Name 2"), max_length=50)

        person2_dob = models.DateField()

        def __str__(self):

            return self.user.username

    # forms.py

    class CreateSingleProfileForm(forms.ModelForm):

        class Meta:

            model = ProfileSingle

            fields = ('user', 'person1_name', 'person1_dob')

            labels = {'user': _('Username'), 'person1_name': _(

                'Person 1 Name'), 'person1_dob': _('Person 1 DOB')}

    

    class CreateCoupleProfileForm(forms.ModelForm):

        class Meta:

            model = ProfileCouple

            ...

    # profile_single_create.html

    <div class="container mt-4">

      <h1>Create Your Profile</h1>

      <form method="post">{% csrf_token %}

          {{ form.as_p }}

          <input type="submit" value="Save">

      </form>

    </div>

    # profile_couple_create.html

    (Code similar to single template)

I know that with CBVs, Django will build the form for me.  But there will be times when I need to customize the form as I do here. What am I missing?

Hi Robert

Just looking at the code

Why do you change context to empty?

context = {}

            return render(request, self.template_name, context)
