[web2py] Re: Hiding fields in a form, depending on a drop down list

[hamdy.a.farag]

more clarification please?

you can do something like the following [just the logic]

db.define_table('my_table', Field('x',.....), Field('y',....))

in your controller
query = (db.y.id>0)
my_list = [row.name for row in db(query).select()]
db.my_table.y.requires=IS_IN_LIST(my_list)
if var not in my_list:      # var is what you're searching for
   db.my_table.x.readable=Falseng
   db.my_table.x.writable=False

def index():

   form = SQLFORM(db.my_table)
   ......
