A StreamBlock can now have NON_FIELD_ERRORS as part of its error dict.
These will be displayed as error messages above the StreamBlock in the
admin upon form submission.
No code in Wagtail currently makes use of this feautre. It is available
for developers of sites to use in their custom StreamField blocks.
The admin extensions in django treebeard 3.0 are not compatible with
Django 1.9. Although these are not used by Wagtail they are used in
other projects (e.g. Oscar), so we should allow treebeard 4.0 which
is compatible with Django 1.9.
The raw html which can be found on the repository states:
Update 08/09/2015: This tutorial has been written during the first days of Wagtail, when documentation and tutorials about it were sparce; right now it should be considered by all accounts obsolete and not be followed! Instead, you should read the official (and very well written) tutorial in the official Wagtail documentation!
Generating links with `link text <./path/to/doc#anchor>`__ does not work for html.
It produces a link to `./path/to/doc#anchor` instead of `./path/to/doc.html#anchor`.
It would be tempting to add `.html` before `#` but would likely cause some more issues
when generating the documentation as pdf or epub.
References on the other hand will work regardless of the output format.
The construct_homepage_summary_items hook allows to add items, but if
you use exactly the same markup as wagtail you end up with a bad layout
because the items form rows with no whitespace between them.
This commit changes the padding-bottom of the section into a margin-bottom
of it's <li> items, meaning that they form rows with enough whitespace
in between them, and the whitespace at the bottom is preserved.
