app, and I have a model called User. In this model I have a boolean value called isagirl. A user must specify if it is a girl or not, which is done by two radio buttons. In my model I have this: validates_presence_of :isagirl, :message => "You must be either a Boy or a Girl. If not, please contact us." However, when I don't specify a sex, I'm seeing this: Isagirl You must

For example, I have a partial that outputs the error messages after validation fails.
- <% errors.each do |attribute, message| -%> <% if message.is_a?(String)%>
- <%= message %> <% end %> <% end -%> Notice that this does not output the attribute. You just need to make sure that all your messages makes sense without an attribute name. share|improve this answer answered Feb 15 '10 at 22:08 Randy Simon 2,7731318 Okay, but how does that code know which form you want? –user142019 Feb 15 '10 at 22:11 add a comment| up vote 5 down vote In one of my pro

You will learn how http://guides.rubyonrails.org/v2.3.11/activerecord_validations_callbacks.html to validate the state of objects before they go into the database, and how to perform custom operations at certain points in the object lifecycle. After reading this guide and trying out the presented concepts, we hope that you'll be able to: Understand the lifecycle of Active Record objects Use the built-in Active Record validation helpers Create your own custom validation methods Work with the error messages generated by the validation process Create callback methods that respond to events in the object lifecycle Create special classes that encapsulate common behavior for your callbacks Create Observers that respond to lifecycle events outside of the original class Chapters The Object LifecycleValidations OverviewWhy Use Validations?

Here is the best guess. rails 3 validates_presence_of validates_presence_of(*attr_names) public Validates that the specified attributes are not blank (as defined by Object#blank?), and, if the attribute is an association, that the associated object is not marked for destruction. Happens by default on save. class Person < ActiveRecord::Base has_one :face validates_presence_of :face end The face attribute must be in the object and it cannot be blank or marked for destruction. If you want to validate the presence of a boolean field (where the real values are true and false), you will want to use validates_inclusion_of :field_name, in: [true, false]. This is due to the way Object#blank? handles boolean values: false.blank? # => true. This validator defers to the ActiveModel validation for presence, adding the check to see that an associated object is not marked for destruction. This prevents the parent object from validating successfully and saving, which then deletes the associated object, thus putting the parent object into an invalid state. Configuration
Rails 3, Validates, Custom Message John T. (johnt519) on 2010-10-03 18:07 In Rails < 3, I could have a validation on model such as: validates_presence_of :name, :message => "some custom message here" If I try something similar in Rails 3: validates :name, :presence => true , :message => "some other custom message" obviously, it throws an exception. So the question is, in Rails 3, how to you give a simple custom message? Do I need to go through and set up a custom validation class for each validation, just to show a different message? I've looked at: http://www.railsapi.com/doc/rails-v3.0.0/classes/A... but it seems to show that a custom class would need to be set up for each attribute of my models? I'm sure there's a shortcut, but have yet to find it. Thanks.

The syntax you gave, however throws a syntax error.
