Hi, Correct me if I am wrong but there doesn''t seem to be an easy way to add validation outside the pre-built ones (validates_presence_of, validates_lenght_of, etc.).

Hello again! I have a action that lists users and that allows an admin user to create new users. When the admin user creates a new user an e-mail is sent to the created user telling him to register in the site.

Hey all, I have two form fields (select dropdowns) that are ''startlocation'' and ''endlocation''. These two cannot be equal to each other on save and I am wondering how to put validation into the model for this. Is is possible to do it in the model, or do I need to do this in the controller?

Hi all, Is there a way to invoke validations at times other than save, create and update?

I want to add a custom validator in one of Model. For example Rails has inbuilt validation methods like validates_uniqueness_of, validates_presence_of .

Please help me by suggesting how i can do this. -- Posted via

Hi, I want to validate my puppet manifests before I check them into source control.
