Oh good. Thanks for the response. I added the format and it worked.
But, here I have one problem. In the table(subject_class) I am only having
a combination of two foreign keys and no other columns. So, adding the
format to any/both of those values will only show an integer in the
dropdown which will be meaningless.
db.define_table('subject_class',
Field('class_id', 'reference class_tbl'),
Field('subject_id', 'reference subject_bs')
)
So, for the format in the table subject_class alone, is there a way to show
the columns in (class_tbl/subject_bs) table which contains meaningful
string columns. If done, in the dropdowns, it will be easier to select the
entries which provide the meaningful information instead a number.
