Django: How to change a field widget in a Inline Formset
As of Django 1.6, you can use the widgets parameter of modelformset_factory in order to customize the widget of a particular field:
AuthorFormSet = modelformset_factory(Author, widgets={ 'name': Textarea(attrs={'cols': 80, 'rows': 20})})and therefore the same parameter for inlineformset_factory (which uses modelformset_factory):
AuthorInlineFormSet = inlineformset_factory(Author, Book, fields=['name'], widgets={ 'name': Textarea(attrs={'cols': 80, 'rows': 20})})
This is an example of customizing one field using formfield_callback:
def formfield_callback(field): if isinstance(field, models.ChoiceField) and field.name == 'target_field_name': return fields.ChoiceField(choices = SAMPLE_CHOICES_LIST, label='Sample Label') return field.formfield()FormSet = inlineformset_factory(ModelA, ModelB, extra=1, formfield_callback = formfield_callback)
You need to define a form and update widget in the Meta class. Look at Overriding the default field types or widgets
