Readonly fields in django formset
django, django-forms, python
Solution
I'd recommend specifying a form to use for the model, and in that form you can set whatever attributes you want to read only.
#forms.py
class AuthorForm(forms.ModelForm):
class Meta:
model = Author
def __init__(self, *args, **kwargs):
super(AuthorForm, self).__init__(*args, **kwargs)
if self.instance.id:
self.fields['weight'].widget.attrs['readonly'] = True
#views.py
AuthorFormSet = modelformset_factory(Author, extra=2, form=AuthorForm)
Problem
I'm using modelformset factory to generate formset from model fields. Here i want to make only the queryset objects as readonly and other (extra forms) as non readonly fields How can i achieve this? ``` AuthotFormSet = modelformset_factory(Author, extra=2,) formset = AuthorFormSet(queryset=Author.objects.all()) ``` In Above formset i wanted to display all the queryset objects as readonly, and remaining extra forms as non readonly fields. How can i achive this? if i used, ``` for form in formset.forms: form.fields['weight'].widget.attrs['readonly'] = True ``` This will convert all the forms (including extra) fields to readonly which i dont want. And also i'm using jquery plugin to add form dynamically to the formset
