I want to add a custom attribute so that I can decide which customwidget
has to be used for a form field connected to that field.
Example:
db.define_table('person',
Field('salutation', mycustomwidget='select2', label = T('Salutation'),
requires=IS_IN_SET(GENDER), represent=lambda v, r: GENDER[v]),
Field('first_name', label = T('First Name')),
format = '%(last_name)s')
I had no luck defining that custom attribute the way it is described in the
book. How and and where would I define such a custom attribute
'mycustomwidget' for the table 'person' or even better for all tables?
Adding attributes to fields and tables
If you need to add custom attributes to fields, you can simply do this:
1
db.table.field.extra = {}
"extra" is not a keyword ; it's a custom attributes now attached to the
field object. You can do it with tables too but they must be preceded by an
underscore to avoid naming conflicts with fields:
1
db.table._extra = {}
