get_context_data(**kwargs)Link to this definition#

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

modelLink to this definition#

A model class. Can be explicitly provided, otherwise will be determined by examining self.object or queryset.

fieldsLink to this definition#

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_urlLink to this definition#

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()Link to this definition#

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()Link to this definition#

Add the current instance (self.object) to the standard get_form_kwargs().

get_success_url()Link to this definition#

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)Link to this definition#

Saves the form instance, sets the current object for the view, and redirects to get_success_url().

form_invalid(form)Link to this definition#

Renders a response, providing the invalid form as context.

A mixin that provides basic HTTP GET and POST workflow.

メソッドと属性

get(request, *args, **kwargs)Link to this definition#

Renders a response using a context created with get_context_data().

post(request, *args, **kwargs)Link to this definition#

Constructs a form, checks the form for validity, and handles it accordingly.

put(*args, **kwargs)Link to this definition#

The PUT action is also handled and passes all parameters through to post().

Enables handling of the DELETE HTTP action.

メソッドと属性

success_urlLink to this definition#

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)Link to this definition#

Retrieves the target object and calls its delete() method, then redirects to the success URL.

get_success_url()Link to this definition#

Returns the url to redirect to when the nominated object has been successfully deleted. Returns success_url by default.
