you can use a list:string field which will store values in a Python list.
then if user type "I am alergic to : peanut" and "I like to eat : banana"
you have a list with
["I am alergic to : peanut", "I like to eat : banana"]
Internally dal stores a pipe | separated string in db.
records = db(query).select()
for row in records:
for item in row.custom:
print 'user defined %s with value %s' % item.split(':')
note you will need to create a custom valudator to ensure that each value in
custom field is separated with :
this is the easiest way. may be not the best.
