# Model Form Functions

Model Form API reference. For introductory material about model forms, see the Creating forms from models topic guide.

## `modelform_factory`

`modelform_factory`(model, form=ModelForm, fields=None, exclude=None, formfield_callback=None, widgets=None, localized_fields=None, labels=None, help_texts=None, error_messages=None, field_classes=None)

  Returns a `ModelForm` class for the given `model`. You can optionally pass a `form` argument to use as a starting point for constructing the `ModelForm`.

  `fields` is an optional list of field names. If provided, only the named fields will be included in the returned fields.

  `exclude` is an optional list of field names. If provided, the named fields will be excluded from the returned fields, even if they are listed in the `fields` argument.

  `formfield_callback` is a callable that takes a model field and returns a form field.

  `widgets` is a dictionary of model field names mapped to a widget.

  `localized_fields` is a list of names of fields which should be localized.

  `labels` is a dictionary of model field names mapped to a label.

  `help_texts` is a dictionary of model field names mapped to a help text.

  `error_messages` is a dictionary of model field names mapped to a dictionary of error messages.

  `field_classes` is a dictionary of model field names mapped to a form field class.

  See ModelForm factory function for example usage.

  You must provide the list of fields explicitly, either via keyword arguments `fields` or `exclude`, or the corresponding attributes on the form’s inner `Meta` class. See Selecting the fields to use for more information. Omitting any definition of the fields to use will result in an `ImproperlyConfigured` exception.

  The `field_classes` keyword argument was added.

## `modelformset_factory`

`modelformset_factory`(model, form=ModelForm, formfield_callback=None, formset=BaseModelFormSet, extra=1, can_delete=False, can_order=False, max_num=None, fields=None, exclude=None, widgets=None, validate_max=False, localized_fields=None, labels=None, help_texts=None, error_messages=None, min_num=None, validate_min=False, field_classes=None)

  Returns a `FormSet` class for the given `model` class.

  Arguments `model`, `form`, `fields`, `exclude`, `formfield_callback`, `widgets`, `localized_fields`, `labels`, `help_texts`, `error_messages`, and `field_classes` are all passed through to `modelform_factory()`.

  Arguments `formset`, `extra`, `max_num`, `can_order`, `can_delete` and `validate_max` are passed through to `formset_factory()`. See formsets for details.

  See Model formsets for example usage.

  The `field_classes` keyword argument was added.

## `inlineformset_factory`

`inlineformset_factory`(parent_model, model, form=ModelForm, formset=BaseInlineFormSet, fk_name=None, fields=None, exclude=None, extra=3, can_order=False, can_delete=True, max_num=None, formfield_callback=None, widgets=None, validate_max=False, localized_fields=None, labels=None, help_texts=None, error_messages=None, min_num=None, validate_min=False, field_classes=None)

  Returns an `InlineFormSet` using `modelformset_factory()` with defaults of `formset=``BaseInlineFormSet`, `can_delete=True`, and `extra=3`.

  If your model has more than one `ForeignKey` to the `parent_model`, you must specify a `fk_name`.

  See Inline formsets for example usage.

  The `field_classes` keyword argument was added.
