class models.BaseModelFormSet
Like regular formsets, Django provides a couple of enhanced formset classes that make it easy to work with Django models. Let’s reuse the Author model from above:
>>> from django.forms import modelformset_factory
>>> from myapp.models import Author
>>> AuthorFormSet = modelformset_factory(Author, fields=('name', 'title'))
Using fields restricts the formset to use only the given fields. Alternatively, you can take an “opt-out” approach, specifying which fields to exclude:
>>> AuthorFormSet = modelformset_factory(Author, exclude=('birth_date',))
This will create a formset that is capable of working with the data associated with the Author model. It works just like a regular formset:
>>> formset = AuthorFormSet() >>> print(formset) <input type="hidden" name="form-TOTAL_FORMS" value="1" id="id_form-TOTAL_FORMS" /><input type="hidden" name="form-INITIAL_FORMS" value="0" id="id_form-INITIAL_FORMS" /><input type="hidden" name="form-MAX_NUM_FORMS" id="id_form-MAX_NUM_FORMS" /> <tr><th><label for="id_form-0-name">Name:</label></th><td><input id="id_form-0-name" type="text" name="form-0-name" maxlength="100" /></td></tr> <tr><th><label for="id_form-0-title">Title:</label></th><td><select name="form-0-title" id="id_form-0-title"> <option value="" selected="selected">---------</option> <option value="MR">Mr.</option> <option value="MRS">Mrs.</option> <option value="MS">Ms.</option> </select><input type="hidden" name="form-0-id" id="id_form-0-id" /></td></tr>
Note
modelformset_factory() uses formset_factory() to generate formsets. This means that a model formset is just an extension of a basic formset that knows how to interact with a particular model.
