get_paginate_by(queryset) Returns the number of items to paginate by, or None for no pagination. By default this returns the value of paginate_by.
django.ref.class-based-views.mixins-multiple-object#django.views.generic.list.MultipleObjectMixin.get_paginate_by
get_paginate_orphans() An integer specifying the number of “overflow” objects the last page can contain. By default this returns the value of paginate_orphans.
django.ref.class-based-views.mixins-multiple-object#django.views.generic.list.MultipleObjectMixin.get_paginate_orphans
get_paginator(queryset, per_page, orphans=0, allow_empty_first_page=True) Returns an instance of the paginator to use for this view. By default, instantiates an instance of paginator_class.
django.ref.class-based-views.mixins-multiple-object#django.views.generic.list.MultipleObjectMixin.get_paginator
get_queryset() Get the list of items for this view. This must be an iterable and may be a queryset (in which queryset-specific behavior will be enabled).
django.ref.class-based-views.mixins-multiple-object#django.views.generic.list.MultipleObjectMixin.get_queryset
model The model that this view will display data for. Specifying model = Foo is effectively the same as specifying queryset = Foo.objects.all(), where objects stands for Foo’s default manager.
django.ref.class-based-views.mixins-multiple-object#django.views.generic.list.MultipleObjectMixin.model
ordering A string or list of strings specifying the ordering to apply to the queryset. Valid values are the same as those for order_by().
django.ref.class-based-views.mixins-multiple-object#django.views.generic.list.MultipleObjectMixin.ordering
page_kwarg A string specifying the name to use for the page parameter. The view will expect this parameter to be available either as a query string parameter (via request.GET) or as a kwarg variable specified in the URLconf. Defaults to page.
django.ref.class-based-views.mixins-multiple-object#django.views.generic.list.MultipleObjectMixin.page_kwarg
paginate_by An integer specifying how many objects should be displayed per page. If this is given, the view will paginate objects with paginate_by objects per page. The view will expect either a page query string parameter (via request.GET) or a page variable specified in the URLconf.
django.ref.class-based-views.mixins-multiple-object#django.views.generic.list.MultipleObjectMixin.paginate_by
