init(self, child_class, child_key=None, foreign_key=None, column=None, title=None, has_default=None, cache=True)
(Constructor)

source code

Parameters:

cache - Indicates whether the relationship object shall keep a copy of the child object in the dbobj for faster access.

Overrides: relationship.__init__

__set_from_result__(self, ds, dbobj, value)

source code

None

Overrides: relationship.__set_from_result__

__init_dbclass__(self, dbclass, attribute_name)

source code

This methods gets called by dbobject's metaclass. It supplies the db property with info about the class it belongs to and its attribute name.

Overrides: datatypes.datatype.__init_dbclass__: (inherited documentation)

get(self, dbobj, owner)

source code

See the Python Language Reference, chapter 3.3.2.2 for details on how this works. Be sure to be in a relaxed, ready-for-hard-figuring mood.

Overrides: datatypes.datatype.__get__: (inherited documentation)

set(self, dbobj, value)

source code

Set the child object to `value'. If the child object has not been inserted, yet it will be by this function.

Overrides: datatypes.datatype.__set__

isset(self, dbobj)

source code

Returns:: True. Most relationships are always set, even if they return [] or the like.

Overrides: relationship.isset: (inherited documentation)

convert(self, value)

source code

Relationships do not need a convert method or can't use it anyway.

Overrides: relationship.__convert__: (inherited documentation)

sql_literal(self, dbobj)

source code

This relationship cannot be represented as an SQL literal.

Overrides: relationship.sql_literal: (inherited documentation)
