So, for my example, I tried your suggestion. I defined a widget in
models/widgets.py:
def units_widget(field,value,food_id):
...
and then in the controller, I set the widget with:
db.ate.units.widget = units_widget(food_id)
But here I am not passing field and value so I get an error. What
You need to make your widget a class so you can pass args to it in the
constructor:
class Units_Widget(object):
def __init__(**args):
def widget(f,v):
#build your widget
#using args
return widget
db.ate.units.widget = Units_Widget(food_id)

Sorry, the constructor should be:
def __init__(*args,**kargs):

I get the following error:
TypeError: __init__() should return None, not 'function'
I think the problem has to do with the following return statement in
the constructor:
return widget

Also, if i wanted to extend SQLFORM.widgets.options.widget, how would
i go about doing that? Is it as simple as replacing:
class Units_Widget(object):
with:
class Units_Widget(SQLFORM.widgets.options.widget):
Thanks,

It depends on what specifically you are trying to accomplish.
You could set the validator instead, for example:
rr=db(db.food.name.like('m%')).select()
db.ate.food_id.requires=IS_IN_SET([(r.id,r.name) for r in rr])

Not sure if this is what you are asking.
