@ -1468,10 +1468,9 @@ Behind the scenes, Django creates an intermediary join table to represent the
many-to-many relationship. By default, this table name is generated using the
name of the many-to-many field and the name of the table for the model that
contains it. Since some databases don't support table names above a certain
length, these table names will be automatically truncated to 64 characters and a
uniqueness hash will be used. This means you might see table names like
``author_books_9cdf4``; this is perfectly normal. You can manually provide the
name of the join table using the :attr:`~ManyToManyField.db_table` option.
