Hi all, Is there a way to invoke validations at times other than save, create and update? I know that I can do this by writing my own validation checks using errors.add_[blah], but I''d like to leverage the existing validation code. What I have is two sets of fields in a record, set A and set B. Both sets must be validated on record create. However, the trouble is that after

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.

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.). Ideally there should be something like: Class Person < ActiveRecord::Base validates :my_method, :on => create, :message => ''was not valid'' def my_method(param) false unless

Hi All, I am modifying typo so as, I can host multiple blogs on the same typo. And its almost done, except that...i am stuck at one place.

Hi! I have a legacy table that has a column named "type" and need to remove this automatic subclassing by ActiveRecord. The api pages are vague about this, and I tried self.inheritance_column = "xtype" which seemed to get me half-way. In the validate_on_create method, the value of self.type was my model Class name. How would you disable this feature? -- Posted via

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.

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?
