Model Form Functions
|
|
====================
|
|
|
|
Model Form API reference. For introductory material about model forms, see the
|
|
:doc:`/topics/forms/modelforms` topic guide.
|
|
|
|
.. module:: django.forms.models
|
|
:synopsis: Django's functions for building model forms and formsets.
|
|
|
|
``modelform_factory``
|
|
=====================
|
|
|
|
.. function:: 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 :class:`~django.forms.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 :ref:`modelforms-factory` 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 :ref:`modelforms-selecting-fields` for more
|
|
information. Omitting any definition of the fields to use will result in
|
|
an :exc:`~django.core.exceptions.ImproperlyConfigured` exception.
|
|
|
|
``modelformset_factory``
|
|
========================
|
|
|
|
.. function:: 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, absolute_max=None, can_delete_extra=True)
|
|
|
|
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 :func:`~django.forms.models.modelform_factory`.
|
|
|
|
Arguments ``formset``, ``extra``, ``can_delete``, ``can_order``,
|
|
``max_num``, ``validate_max``, ``min_num``, ``validate_min``,
|
|
``absolute_max``, and ``can_delete_extra`` are passed through to
|
|
:func:`~django.forms.formsets.formset_factory`. See :doc:`formsets
|
|
</topics/forms/formsets>` for details.
|
|
|
|
See :ref:`model-formsets` for example usage.
|
|
|
|
.. versionchanged:: 3.2
|
|
|
|
The ``absolute_max`` and ``can_delete_extra`` arguments were added.
|
|
|
|
``inlineformset_factory``
|
|
=========================
|
|
|
|
.. function:: 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, absolute_max=None, can_delete_extra=True)
|
|
|
|
Returns an ``InlineFormSet`` using :func:`modelformset_factory` with
|
|
defaults of ``formset=``:class:`~django.forms.models.BaseInlineFormSet`,
|
|
``can_delete=True``, and ``extra=3``.
|
|
|
|
If your model has more than one :class:`~django.db.models.ForeignKey` to
|
|
the ``parent_model``, you must specify a ``fk_name``.
|
|
|
|
See :ref:`inline-formsets` for example usage.
|
|
|
|
.. versionchanged:: 3.2
|
|
|
|
The ``absolute_max`` and ``can_delete_extra`` arguments were added.
