FormMixin¶django.views.generic.edit.FormMixin¶フォームを作成したり表示したりする機能を提供するmixinクラス。
ミックスイン
メソッドと属性
initial¶フォームの初期化データのディクショナリ。
form_class¶インスタンス化するフォームクラス。
success_url¶フォームが正常に処理されたときにリダイレクトするURL。
get_form_class()¶Retrieve the form class to instantiate. By default
form_class.
get_form(form_class=None)¶Instantiate an instance of form_class using
get_form_kwargs().
If form_class isn't provided get_form_class() will be used.
get_form_kwargs()¶フォームのインスタンス化に必要なキーワード引数を構築します。
The initial argument is set to get_initial(). If the
request is a POST or PUT, the request data (request.POST
and request.FILES) will also be provided.
get_success_url()¶Determine the URL to redirect to when the form is successfully
validated. Returns
success_url by default.
form_valid(form)¶Redirects to
get_success_url().
form_invalid(form)¶Renders a response, providing the invalid form as context.
get_context_data(**kwargs)¶Calls get_form() and adds the result to the context data with the
name 'form'.
ModelFormMixin¶django.views.generic.edit.ModelFormMixin¶A form mixin that works on ModelForms, rather than a standalone form.
Since this is a subclass of
SingleObjectMixin, instances of this
mixin have access to the
model and
queryset attributes,
describing the type of object that the ModelForm is manipulating.
If you specify both the
fields and
form_class attributes, an
ImproperlyConfigured exception will be
raised.

メソッドと属性
model¶A model class. Can be explicitly provided, otherwise will be determined
by examining self.object or
queryset.
fields¶A list of names of fields. This is interpreted the same way as the
Meta.fields attribute of ModelForm.
This is a required attribute if you are generating the form class
automatically (e.g. using model). Omitting this attribute will
result in an ImproperlyConfigured
exception.
success_url¶フォームが正常に処理されたときにリダイレクトするURL。
success_url may contain dictionary string formatting, which
will be interpolated against the object's field attributes. For
example, you could use success_url="/polls/{slug}/" to
redirect to a URL composed out of the slug field on a model.
get_form_class()¶Retrieve the form class to instantiate. If
form_class is provided,
that class will be used. Otherwise, a ModelForm will be
instantiated using the model associated with the
queryset, or
with the model,
depending on which attribute is provided.
get_form_kwargs()¶Add the current instance (self.object) to the standard
get_form_kwargs().
get_success_url()¶Determine the URL to redirect to when the form is successfully
validated. Returns
django.views.generic.edit.ModelFormMixin.success_url if it is
provided; otherwise, attempts to use the get_absolute_url() of the
object.
form_valid(form)¶Saves the form instance, sets the current object for the view, and
redirects to
get_success_url().
form_invalid(form)¶Renders a response, providing the invalid form as context.
ProcessFormView¶django.views.generic.edit.ProcessFormView¶A mixin that provides basic HTTP GET and POST workflow.
注釈
This is named 'ProcessFormView' and inherits directly from
django.views.generic.base.View, but breaks if used
independently, so it is more of a mixin.

メソッドと属性
get(request, *args, **kwargs)¶Renders a response using a context created with
get_context_data().
post(request, *args, **kwargs)¶Constructs a form, checks the form for validity, and handles it accordingly.
DeletionMixin¶django.views.generic.edit.DeletionMixin¶Enables handling of the DELETE HTTP action.
メソッドと属性
success_url¶The url to redirect to when the nominated object has been successfully deleted.
success_url may contain dictionary string formatting, which will be
interpolated against the object's field attributes. For example, you
could use success_url="/parent/{parent_id}/" to redirect to a URL
composed out of the parent_id field on a model.
delete(request, *args, **kwargs)¶Retrieves the target object and calls its delete() method, then
redirects to the success URL.
get_success_url()¶Returns the url to redirect to when the nominated object has been
successfully deleted. Returns
success_url by
default.
