I've got the following table definition.
def set_requirement(edg_edge): db.edg_edge.label.requires=[IS_IN_DB(db_st,
'st_edge_label.name', '%(name)s', zero=T("Select a value")),
IS_NOT_IN_DB(db((db.edg_edge.fromID==request.vars.fromID) &
(db.edg_edge.toID==request.vars.toID)), db.edg_edge.label,
error_message='Realtie al in database')]
db.define_table('edg_edge',
Field('fromID', 'reference vtx_vertex', default='',
requires=[IS_IN_DB(db, 'vtx_vertex.id', '%(name)s', zero=T("Select a
value"))], notnull=True),
Field('toID', 'reference vtx_vertex', default='',
requires=[IS_IN_DB(db, 'vtx_vertex.id', '%(name)s', zero=T("Select a
value"))], notnull=True'),
Field('label', length=128, default='', notnull=True,
widget=SQLFORM.widgets.options.widget),
on_define = set_requirement,
migrate = False)
To prevent the user form entering the same edge twice I defined the 3 field
validator. However it does not
work and I do not see what's wrong with my code.
The user can enter:
fromID toID label
2 3 sponsor
2 3 sponsor
which the validator should prevent.
Kind regards,
Annet
