The following mixins are used to construct Django’s editing views:
\nFormMixinLink para este cabeçalho#A mixin class that provides facilities for creating and displaying forms.
\nMixins
\n\nMétodos e Atributos
\nUm dicionário contendo dados iniciais para o formulário.
\nA classe do “form” para instanciar.
\nA URL de redirecionamento para quando o “form” for processador com sucesso.
\nThe prefix for the generated form.
Retrieve initial data for the form. By default, returns a copy of\ninitial.
Retrieve the form class to instantiate. By default\nform_class.
Instantiate an instance of form_class using\nget_form_kwargs().\nIf form_class isn’t provided get_form_class() will be used.
Build the keyword arguments required to instantiate the form.
\nThe initial argument is set to get_initial(). If the\nrequest is a POST or PUT, the request data (request.POST\nand request.FILES) will also be provided.
Determine the prefix for the generated form.\nReturns prefix by default.
Determine the URL to redirect to when the form is successfully\nvalidated. Returns\nsuccess_url by default.
Redirects to\nget_success_url().
Renders a response, providing the invalid form as context.
\nCalls get_form() and adds the result to the context data with the\nname ‘form’.
ModelFormMixinLink para este cabeçalho#A form mixin that works on ModelForms, rather than a standalone form.
Since this is a subclass of\nSingleObjectMixin, instances of this\nmixin have access to the\nmodel and\nqueryset attributes,\ndescribing the type of object that the ModelForm is manipulating.
If you specify both the\nfields and\nform_class attributes, an\nImproperlyConfigured exception will be\nraised.
Mixins
\n\nMétodos e Atributos
\nA model class. Can be explicitly provided, otherwise will be determined\nby examining self.object or\nqueryset.
A list of names of fields. This is interpreted the same way as the\nMeta.fields attribute of ModelForm.
This is a required attribute if you are generating the form class\nautomatically (e.g. using model). Omitting this attribute will\nresult in an ImproperlyConfigured\nexception.
A URL de redirecionamento para quando o “form” for processador com sucesso.
\nsuccess_url may contain dictionary string formatting, which\nwill be interpolated against the object’s field attributes. For\nexample, you could use success_url="/polls/{slug}/" to\nredirect to a URL composed out of the slug field on a model.
Retrieve the form class to instantiate. If\nform_class is provided,\nthat class will be used. Otherwise, a ModelForm will be\ninstantiated using the model associated with the\nqueryset, or\nwith the model,\ndepending on which attribute is provided.
Add the current instance (self.object) to the standard\nget_form_kwargs().
Determine the URL to redirect to when the form is successfully\nvalidated. Returns\ndjango.views.generic.edit.ModelFormMixin.success_url if it is\nprovided; otherwise, attempts to use the get_absolute_url() of the\nobject.
Saves the form instance, sets the current object for the view, and\nredirects to\nget_success_url().
Renders a response, providing the invalid form as context.
\nProcessFormViewLink para este cabeçalho#A mixin that provides basic HTTP GET and POST workflow.
\n\nExtends
\n\nMétodos e Atributos
\nRenders a response using a context created with\nget_context_data().
Constructs a form, checks the form for validity, and handles it\naccordingly.
\nThe PUT action is also handled and just passes all parameters\nthrough to post().
DeletionMixinLink para este cabeçalho#Enables handling of the DELETE http action.
Métodos e Atributos
\nThe url to redirect to when the nominated object has been\nsuccessfully deleted.
\nsuccess_url may contain dictionary string formatting, which will be\ninterpolated against the object’s field attributes. For example, you\ncould use success_url="/parent/{parent_id}/" to redirect to a URL\ncomposed out of the parent_id field on a model.
Retrieves the target object and calls its delete() method, then\nredirects to the success URL.
Returns the url to redirect to when the nominated object has been\nsuccessfully deleted. Returns\nsuccess_url by\ndefault.
