How to add Widgets to UpdateView in Django

Question

I need to add this widget to the django UpdateView,

class tlistUpdate(LoginRequiredMixin,UpdateView):
    fields = ('title', 'thumbnail', 'content', 'tags')
    model = htmlpage
    template_name = 'blog/create_form.html'

Tried adding

widgets = {
    'content': SummernoteWidget(),
}

and

content = forms.CharField(widget=SummernoteWidget())

But it did't work.

The UpdateView is not constructed to handle advanced form construction. The idea is that you use fields if you aim to construct a simple (standard) Form.

You can simply construct a ModelForm and use that form in your CreateView/UpdateView:

# app/forms.py

from django import forms

class HtmlPageForm(forms.ModelForm):
    class Meta:
        model = HtmlPage
        fields = ('title', 'thumbnail', 'content', 'tags')
        widgets = {
            'content': SummernoteWidget
        }

In your views.py you can then use the form by setting the form_class attribute [Django-doc]:

# app/views.py

from app.forms import HtmlPageForm

class TlistUpdate(LoginRequiredMixin,UpdateView):
    model = htmlpage
    form_class = HtmlPageForm
    template_name = 'blog/create_form.html'

Note: normally a Django models, just like all classes in Python are given a name in PerlCase, not snake_case, so it should be: HtmlPage instead of htmlpage.
