When building a dummy request, you can now pass in the original request object
to add additional information to the dummy. Currently, that includes the
following headers:
REMOTE_ADDR
HTTP_X_FORWARDED_FOR
HTTP_COOKIE
HTTP_USER_AGENT
More may be added later.
This changes ensures that middleware which work on the client IP aren't flumuxed
by its absense, and also makes it possible for previews to be rendered as the
logged in user (they had previously been rendered using an AnnonymousUser).
Because the user's logged in state is now detectable in a Page previews, the
Wagtail userbar now hides itself explicitly during previews, rather than relying
on the fact that previews used to be built with AnonymousUser.
As mentioned in the comments I didn't see the first pull request (https://github.com/torchbox/wagtail/pull/2509)
However, I think my changes were a tiny bit more complete in terms of UI/UX. I allow to delete a user directly from the user list + you can delete any user if you are superuser, except yourself. This way we are sure to keep at least one superuser but we can still delete superusers.
I added some tests from this PR to my code and also added the permission denied on the delete page.
Update render and render_basic methods on Block to take a context kwarg
Update TableBlock to support passing extra context to render
Implement render_as_block on BoundBlock, StreamValue and StructValue.
Collectively, these are the objects encountered during template rendering which typically render
a block template when output inside {{ ... }} tags. Implementing render_as_block allows us to do
the same thing, but passing a template context as well.
Implement include_block tag
Support extra context vars on include_block via 'with foo=bar'
Support 'only' flag on include_block tag, to omit the parent context
Update StreamField documentation to cover the include_block tag
Rewrite 'BoundBlocks and values' docs based on the include_block tag
Add tests for blocks with legacy render / render_basic methods
Any bits of StreamField infrastructure that attempt to call render or render_basic
on a block with a 'context' kwarg, should (for now) also work on blocks that don't
accept the context kwarg, but output a RemovedInWagtail18Warning.
Explicitly test whether render / render_basic will accept a 'context' kwarg
This avoids unexpected behaviour when the method legitimately accepts a context
kwarg, but happens to throw an unrelated TypeError - in this situation, the final
output (or error diagnostics) will behave as if the context was never passed,
making debugging difficult. See https://github.com/torchbox/wagtail/pull/2786#discussion_r69563984
The `form_template` attribute was mentioned in passing in the docs, but was missing various things
to make it fully useful:
- context passed to form_template now includes 'prefix' and 'block_definition'
- context for the form is now populated in a separate overrideable `get_form_context` method
- full documentation and tests for form_template and get_form_context added
