    a b calling the appropriate methods on the wrapped expression.  
    448448        Tells Django that this expression contains an aggregate and that a
    449449        ``GROUP BY`` clause needs to be added to the query.

    453453        Provides the chance to do any pre-processing or validation of
    454454        the expression before it's added to the query. ``resolve_expression()``
    … … Now we implement the pre-processing and validation. Since we do not have  
    579579any of our own validation at this point, we just delegate to the nested
    580580expressions::
