class zds.tutorialv2.models.database.ContentRead(*args, **kwargs)

Small model which keeps track of the user viewing tutorials.

It remembers the PublishableContent they read and what was the last Note at that time.

exception DoesNotExist
exception MultipleObjectsReturned
save(force_insert=False, force_update=False, using=None, update_fields=None)

Save this model but check that if we have not a related note it is because the user is content author.

class zds.tutorialv2.models.database.FakeChapter(chapter, main_container, parent_id)

A simple class that is used by ES to index chapters, constructed from the containers.

In mapping, this class defines PublishedContent as its parent. Also, indexing is done by the parent.

Note that this class is only indexable, not updatable, since it does not maintain value of es_already_indexed

get_es_document_as_bulk_action(index, action='index')

Overridden to handle parenting between chapter and PublishedContent

classmethod get_es_document_type()

value of the _type field in the index

classmethod get_es_mapping()

alias of PublishedContent

class zds.tutorialv2.models.database.PickListOperation(id, content, operation, operation_date, version, staff_user, canceler_user, is_effective)
exception DoesNotExist
exception MultipleObjectsReturned
cancel(canceler, autosave=True)

Cancel a decision :param canceler: staff user :param autosave: if True saves the modification

save(**kwargs)

Saves the current instance. Override this in a subclass if you want to control the saving process.

The ‘force_insert’ and ‘force_update’ parameters can be used to insist that the “save” must be an SQL insert or update (or equivalent for non-SQL backends), respectively. Normally, they should not be set.

class zds.tutorialv2.models.database.PublishableContent(*args, **kwargs)

  • unregistered_user – the user to be unregistered
  • replacement_author – the new author
  • gallery_class – the class to link tutorial with gallery (perhaps overkill :p)

Mixins (mixins.py)

class zds.tutorialv2.mixins.ContentTypeMixin

This class deals with the type of contents and fill context according to that

class zds.tutorialv2.mixins.DoesNotRequireValidationFormViewMixin(**kwargs)

Ensure the content do not require validation before publication.

get_form_kwargs()

Returns the keyword arguments for instantiating the form.

class zds.tutorialv2.mixins.DownloadViewMixin(**kwargs)

Basic View to return a file to download

(inspired from https://djangosnippets.org/snippets/2549/ and http://stackoverflow.com/questions/16286666/send-a-file-through-django-class-based-views)

You just need to override get_contents() to make it works

get(context, **response_kwargs)

Access to a file with only get method then write the file content in response stream. Properly sets Content-Type and Content-Disposition headers

class zds.tutorialv2.mixins.FormWithPreview(**kwargs)
post(request, *args, **kwargs)

Handles POST requests, instantiating a form instance with the passed POST variables and then checked for validity.

class zds.tutorialv2.mixins.ModalFormView(**kwargs)

If self.modal_form is set True, this class will ensure that the redirection is made to the previous page if an error appear

form_invalid(form)

If self.modal_form is set True, this function is rewritten to send back to the previous page with an error message, instead of using the form template which is normally provided.

The redirection is made to form.previous_page_url, if exists, content:view otherwise.

exception zds.tutorialv2.mixins.MustRedirect(*args, **kwargs)

Exception raised when this is not the last version of the content which is called

class zds.tutorialv2.mixins.RequiresValidationViewMixin(**kwargs)

Ensure the content require validation before publication.

class zds.tutorialv2.mixins.SingleContentDetailViewMixin(**kwargs)

This enhanced DetailView ensure,

  • by rewriting get(), that:
    • self.object contains the result of get_object() (as it must be if get() is not rewritten)
    • 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
    • context[‘can_edit’] is set
    • context[‘version’] is set (if different from self.object.sha_draft)
    • context[‘beta_topic’] is set (if any)
get_context_data(**kwargs)

Insert the single object into the context dict.

class zds.tutorialv2.mixins.SingleContentDownloadViewMixin(**kwargs)

Ensure, by rewritring get(), that - self.object contains the result of get_object() (as it must be if get() is not rewritten) - 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()

get(context, **response_kwargs)

Access to a file with only get method then write the file content in response stream. Properly sets Content-Type and Content-Disposition headers

class zds.tutorialv2.mixins.SingleContentFormViewMixin(**kwargs)

This enhanced FormView ensure,

  • by surcharging dispatch(), that:
    • self.object contains the result of get_object() (as for DetailView)
    • self.versioned_object contains the results of get_versioned_object()
  • by surcharging get_context_data(), that
    • context[‘content’] contains self.versioned_object
get_context_data(**kwargs)

Insert the form into the context dict.

class zds.tutorialv2.mixins.SingleContentPostMixin

Base mixin used to get content from post query

get_object(queryset=None)

Get database representation of the content by its pk, then check permissions

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:

  1. 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.
  2. 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.
  3. 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)

This enhanced DetailView ensures,

  • by rewriting get(), that:
    • self.object contains the result of get_object() (as it must be if get() was not rewritten)
    • 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
get_context_data(**kwargs)

    • self.object contains the result of get_object() (as for DetailView)
    • self.versioned_object contains the results of get_versioned_object()
  • by surcharging get_context_data(), that
    • context[‘content’] is set
    • context[‘public_object’] is set

Note: does not catch MustRedirect, so you should not use a slug with POST request

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:

  1. 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.
  2. 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.

get_redirect_url(public_version)

Return the most recent url, based on the current public version
