success_url The URL to redirect to when the form is successfully processed. 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.

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

post(request, *args, **kwargs) Constructs a form, checks the form for validity, and handles it accordingly.

get(request, *args, **kwargs) Renders a response using a context created with get_context_data(). Changed in Django 1.9: Construction of the form was moved from this method to get_context_data().

put(*args, **kwargs) The PUT action is also handled and just passes all parameters through to post().

form_invalid() Renders a response, providing the invalid form as context.

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.

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.

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.

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