 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
 names of the two tables being joined. Since some databases don't support table
-names above a certain length (often 32 characters), these table names will be
-automatically truncated to 32 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.
