similar to: No Custom Validation

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 . What I need is a similar kind of method (example: validates_line_items), that can run my custom code while saving, updating the record and can add custom error messages to the record. Please help me by suggesting how i can do this. -- Posted via

What''s the best way to validate_on_destroy. Rails only seems to include validate_on_create and validate_on_update methods. I don''t want to resort to doing: before_destroy do |j| raise "There is an error" if j.etc end Is there a way of finding out what action (create/update/destroy) is being performed if I use the ''validate'' method? -- Posted via

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. I want to validate the user name and password only when the user register and not when the admin user creates it. Can anyone tell me how to do this? Thanks. Best regards, Hugo --

I have a couple forms that I''d like to be able to validate and automatically populate, but it shouldn''t be based on AR. In fact I often have a bunch of small forms that I can''t really justify writing a whole new model class for anyway.
