Added clarification to the docs, pointing out that unique_for_date only considers the date portion of DateTime fields.
Update customizing.txt

The origin statement "which could be ... or whatever" **misguides** many newbies like me.

In fact, the ``login`` function in ``contrib.auth`` stores ``user.pk`` in session, then ``get_user`` function in ``contrib.auth`` gets ``user.pk`` in session and then passes it to your custom ``get_user`` as ``user_id``.

Which means, ``user_id`` prarameter in your custom ``get_user`` has to be the primary key of ``User`` object, too.
Fixed #20397 - Cleaned up issue with quotation marks in documentation

Fixed #20398 - Added language selection code to example in documentation

Recommend using the bcrypt library instead of py-bcrypt

* py-bcrypt has not been updated in some time
* py-bcrypt does not support Python3
* py3k-bcrypt, a port of py-bcrypt to python3 is not compatible
  with Django
* bcrypt is supported on all versions of Python that Django
  supports

small typo, example pk=27 but description pk=24
Make the example usage of import_by_path less confusing.

Using import_by_path to import import_by_path is a really odd use case
and makes the code example difficult to read.
