class TruncMonth(expression, output_field=None, tzinfo=None, **extra) [source] kind = 'month' These are logically equivalent to Trunc('date_field', kind).

The following are recognized as ending a line: the Unix end-of-line convention '\n', the Windows convention '\r\n', and the old Macint

class Options [source] The model _meta API is at the core of the Django ORM.
