Start with this to get yourself familiar with how validation_callbacks work. Generally, if you are using a form in a view (form_for as an example) you have a form that is backed by the model. Therefore, you are placing the validation checks in the model, not the controller. Viewer -- has form_for... Controller -- Model -- validates_presence_of :name -- validates_..._ .. etc Depending on the type of validation you provide in the model, rails will automatically catch the error if it occurs. Keep in mind that if you are using form_tag you cannot perform model validation callbacks because that form is not backed by a model. You'd have to use javascript, or something else to do validation checks. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
