Django error message in class based view

Question

Can I change the error message from the model for a class-based view? the following is not working, it always gives the default message from Django.

Model:

class Child(models.Model):
   name = models.CharField(max_length=100, error_messages={ 'blank': 'cannot be blank or null', 'null': 'cannot be blank or null',})

view:

class ChildCreate(CreateView):
  model = Child
  fields = '__all__'
  success_url = reverse_lazy('children-list')

you have to create a ModelForm in forms.py and add that form in your view form_class=<your_form_class_name> add the error_message attribute in forms it will work — Shihabudheen K M

From the docs:

Error messages defined at the form field level or at the form Meta level always take precedence over the error messages defined at the model field level.

So you can create model form and add required error message there:

class ChildForm(forms.ModelForm):
    use_required_attribute = False

    class Meta:
        model = models.Child
        fields = '__all__'
        error_messages = {'name': {'required': 'cannot be blank or null'}} 

class ChildCreate(CreateView):
    model = Child
    form_class = forms.ChildForm
    success_url = reverse_lazy('children-list')
