Rails3 data inserting issues

Rails
#1

I am using rails3. when i am trying to insert data into postgrsql got
the
error like this

PGError: ERROR: value too long for type character varying(15)

In the migration file have * t.string
:contact_number,:limit=>15,:null=>false*. this string because the
contact_number will be +91 9387292839. Why getting like this…?

The given error is quite self descriptive: the attribute size limit is
15
characters and you try to assign a longer string to it. Postgres raises
an
exception instead of just cutting it to 15 characters as mysql(for
instance) would do.

You either shouldnt limit your strings or should add a length validation
to
your model.
String defaults to 255; should you need more characters, you’d better
use
Text as type.

Personally, I don’t think its worth to limit strings and save a few
bytes
in your db nowadays.
