I’m using validates_format_of and the validation I want to do works, but
I
can’t get an error message to be displayed if the data is invalid:
validates_format_of :mobile, :with => /\A[+0-9]+\Z/, :message => " -
Wrong"
I have another validation some where else that does display the error
message: " - Name is too long"
validates_length_of :name, :within => 5…40, :too_long => " - Name is
too
long",
validates_length_of :name, :within => 1…50, :message => “Broken” <------
This also works but not for validates_format_of
This also works but not for validates_format_of
You say that you have an example of validates_length_of “somewhere
else” that /does/ work. Are you sure that it is not the “somewhere
else” that is significant. Try replacing the validates_length_of that
is working with a validates_format_of and see if you then get the
message. Also try replacing the format validation that does not show
the error with a validates_length_of.
I tried what you suggested and I got the error message with
validates_format_of where validates_length_of worked, and length_of
didn’t
work where my format_of wasn’t working. So it looks like the “somwhere
else” is significant, but I cant see any obvious differences between the
two models, any suggestions?
