Rails validation error messages: Displaying only one per field
- by Sergio Oliveira Jr.
Rails has an annoying "feature" which displays ALL validation error messages associated with a given field. So for example if I have 3 validates_XXXXX_of :email, and I leave the field blank I get 3 messages in the error list. This is non-sense. It is better to display one messages at a time. If I have 10 validation messages for a field does it mean I will get 10 validation error messages if I leave it blank?
Is there an easy way to correct this problem? It looks straightforward to have a condition like: If you found an error for :email, stop validating :email and skip to the other field.
Ex:
validates_presence_of :name
validates_presence_of :email
validates_presence_of :text
validates_length_of :name, :in = 6..30
validates_length_of :email, :in = 4..40
validates_length_of :text, :in = 4..200
validates_format_of :email, :with = /^([^@\s]+)@((?:[-a-z0-9]+.)+[a-z]{2,})$/i
<%= error_messages_for :comment % gives me:
7 errors prohibited this comment from being saved
There were problems with the following fields:
Name can't be blank
Name is too short (minimum is 6 characters)
Email can't be blank
Email is too short (minimum is 4 characters)
Email is invalid
Text can't be blank
Text is too short (minimum is 4 characters)
