Hi,
I wanted to know where validations placed are most effective: Model,
View or controller.
In my application i enter data in a text box and if it is greater
than a
given value (which varies depending on choice), it should throw an
error
message and data shouldn't be saved.
Thanks,
Premanshu
You've answered your own question here. The Model is responsible for
saving data back to your persistence store (whatever that is) so that
is the logical place for validations to live. More than one controller
can access and send data to your one and only model, they should never
repeat your validations there (DRY).
