- self.sha is set according to self.request.GET[“version”] (if any) and self.object.sha_draft otherwise
- self.versioned_object contains the results of get_versioned_object()
by surcharging get_context_data(), that
- context[“content”] contains self.versioned_object

class zds.tutorialv2.mixins.SingleContentViewMixin

Base mixin to get only one content, and its corresponding versioned content

Deals with URL resolution in the following way:

In get_object():
- Fetch the PublishableContent according to self.kwargs['pk'], self.request.GET['pk'] or self.request.POST['pk'] (one of these have to be defined). Raise Http404 if any.
- Then, check permissions with respect to self.must_be_author and self.authorized_for_staff (and define self.is_staff and self.is_author). Raise PermissionDenied if any.
In get_versioned_object():
- Deal with sha : assume self.object.sha_draft by default, but reset according to self.request.GET['version'], if exists. Then, check self.only_draft_version and raise PermissionDenied if any
- Fetch the VersionedContent. Due to the use of self.object.load_version_or_404(sha), raise Http404.
- Check if its the beta or public version, and allow access if it’s the case. Raise PermissionDenied.
- Check slug if self.kwargs['slug'] is defined. Raise Http404 if any.
In get_public_object(), fetch the last published version, if any

Any redefinition of any of these two functions should take care of those points.

get_object(queryset=None): Get database representation of the content by its pk, then check permissions

get_public_object(): Get the published version, if any

get_versioned_object(): Gets the asked version of current content.

class zds.tutorialv2.mixins.SingleOnlineContentDetailViewMixin(**kwargs)

- Redirection is made if we catch MustRedirect
- self.versioned_object contains a PublicContent object
- self.public_content_object contains a PublishedContent object
by surcharging get_context_data(), that
- context[“content”] is set
- context[“is_staff”] is set
- context[“can_edit”] is set
- context[“public_object”] is set
- context[“is_antispam”] is set
- context[“db_content”] is set with the PublishableContent instance

get_context_data(**kwargs): Insert the single object into the context dict.

- self.versioned_object contains the results of get_versioned_object()
by surcharging get_context_data(), that

get_context_data(**kwargs): Insert the form into the context dict.

class zds.tutorialv2.mixins.SingleOnlineContentViewMixin

Base mixin to get only one content online content

Deals with URL resolution in the following way:

In get_object():
- Fetch the PublicContent according to self.kwargs['pk'], self.request.GET['pk'] or self.request.POST['pk'] 0(one of these have to be defined). Raise Http404 if any.
- Check if self.current_content_type if defined, and use it if it’s the case
- Check if slug is defined, also check object it if it’s the case
- Then, define self.is_staff and self.is_author.
In get_versioned_object(): Fetch the VersionedContent. Due to the use of
self.public_content_object.load_public_version_or_404(), raise Http404 if any.

Any redefinition of any of these two functions should take care of those points.
