Custom Error Message
This plugin gives you the option to not have your custom validation error message prefixed with the attribute name.
This only works with Rails 4
gem 'custom_error_message', git: 'https://github.com/thethanghn/custom-err-msg.git'
Sometimes generated error messages don't make sense.
validates_acceptance_of :accepted_terms, :message => 'Please accept the terms of service'
This generates the error message:
Accepted terms Please accept the terms of service
This plugin uses the carat (^) to omit the name of the attribute from error messages:
validates_acceptance_of :accepted_terms, :message => '^Please accept the terms of service'
This now generates:
Please accept the terms of service
