Making dependent form fields in web2py

[aabhas majumdar]

I have to create a form which has 2 fields source and destination . I have a table Location1 in db.py with source and destination .
I wanted to implement the view such that if i select a source from the drop down list of source then in destination only those destinations will be in drop down list whose source in database is the source entered.
Example:
database:
 SOURCE - DESTINATION
 USA        -   INDIA
 USA        -    JAPAN
 INDIA       -   CHINA
 JAPAN     -   CHINA

now in views if i select USA in SOURCE from dropdown list  of("USA","INDIA","JAPAN")  my destination dropdown list should contain only ("INDIA","JAPAN")
