reviewboard.reviews.views.review_request_updates¶

View for sending data for updating the review request page.

class ReviewRequestUpdatesView(**kwargs)[source]¶

Bases: ReviewRequestViewMixin, ETagViewMixin, ContextMixin, View

Internal view for sending data for updating the review request page.

This view serializes data representing components of the review request page (the issue summary table and entries) that need to periodically update without a full page reload. It’s used internally by the page to request and handle updates.

The resulting format is a custom, condensed format containing metadata information and HTML for each component being updated. It’s designed to be quick to parse and reduces the amount of data to send across the wire (unlike a format like JSON, which would add overhead to the serialization/deserialization time and data size when storing HTML).

Each entry in the payload is in the following format, with all entries joined together:

<metadata length>n <metadata content> <html length>n <html content>

The format is subject to change without notice, and should not be relied upon by third parties.

__init__(**kwargs) → None[source]¶

Initialize the view.

Parameters:: **kwargs (tuple) – Keyword arguments passed to as_view().

pre_dispatch(request: HttpRequest, *args, **kwargs) → Optional[HttpResponse][source]¶

get_etag_data(request: HttpRequest, *args, **kwargs) → str[source]¶

Return an ETag for the view.

Parameters:

request (django.http.HttpRequest) – The HTTP request from the client.
*args (tuple, unused) – Positional arguments passed to the handler.
**kwargs (dict, unused) – Keyword arguments passed to the handler.
