Django 3.0.8 Field.disable UpdateView

For example I have a EntryUpdateForm that inherits from UpdateView that updates some data on a model. Now I'd like to disable certain fields. From the Django documentiation I'm not sure where exatcly to put the Field.disable attribute to disable a certain field on a form.

forms.py



class EntryUpdateForm(UpdateView):

    class Meta:
        model = Entry
        fields = ["material", "shape", "diameter", "taken_from", "moved_to", "quantity"]

views.py


class EntryUpdateView(LoginRequiredMixin, EntryUpdateForm):
    model = Entry
    fields = ["material", "shape", "diameter", "taken_from", "moved_to", "quantity"]

    def form_valid(self, form):
        form.instance.author = self.request.user
        return super().form_valid(form)

I'm not even sure if it's possible to do this if I'm inheriting from the UpdateView, at least easly.

Thanks to a comment from mursalin I managed to get it to work.

forms.py

class EntryForm(forms.ModelForm):
    class Meta:
        model = Entry
        fields = ["material", "shape",  "diameter", "taken_from", "moved_to", "quantity"]

    material = forms.ChoiceField(disabled=True)
    shape = forms.ChoiceField(disabled=True)
    diameter= forms.CharField(disabled=True)  # add whichever field you want to disable


class EntryUpdateForm(UpdateView):

    class Meta:
        model = Entry

views.py

class EntryUpdateView(LoginRequiredMixin, EntryUpdateForm):
    model = Entry
    form_class = EntryForm  # pass the form in the view to get it to change

    def form_valid(self, form):
        form.instance.author = self.request.user
        return super().form_valid(form)

class EntryUpdateForm(UpdateView):
    material =  forms.CharField(widget=forms.TextInput(attrs={'readonly':'True'}))
    class Meta:
        model = Entry
        fields = ["material", "shape", "diameter", "taken_from", "moved_to", "quantity"]

Replace material with whichever field you want to disable and use the appropriate widget
