Model Form FunctionsP

Model Form API reference. For introductory material about model forms, see the 从模型创建表单 topic guide.

modelform_factoryP

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)[源代码]P

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的工厂函数 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 选择要使用的字段 for more information. Omitting any definition of the fields to use will result in an ImproperlyConfigured exception.

modelformset_factoryP

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)[源代码]P

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 模型表单集 for example usage.

inlineformset_factoryP

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)[源代码]P

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.
