similar to: validate_on_destroy ?

I''ve got a user object which has quite a few attributes mapped to the database. As of right now I''ve got some validations in the model like: validates_presence_of :password, :message => "You must specify a valid password." validates_confirmation_of :password, :message => "Password doesn''t match the confirmation." validates_presence_of

i just ran into a problem with some test, and i am not exactly sure why, but the difference happened when i changed my model validation from: validate :custom_validation to: validate_on_create :custom_validation can someone give me any ideas on where in the chain the validation takes place? thanks! -- Posted via http://www.ruby-forum.com/.

Hi! I got a class named EinsatzFilter which I serialized to session. Before saving to session it works afterwards I keep getting the message: "undefined method `to_s'' for #<Person:0x38c6ab8>".

I''m building a little application with Rails, and I''m becoming a huge fan of the validations in ActiveRecord. Recently, though I ran into a problem which to me feels like a job for Validations, but I can''t see a way to use them. My model consits of a Trade object, which represents either buying or selling some security. I need to require that at no point has a user

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 --

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

Please help, I am really at a loss at how validation is supposed to work in rails. Model contains acts_as_tree I want to force my NEW objects to have a parent I do NOT want existing object to have a parent so I only want to have parent_id on create, NOT on update. I am trying this: def validate_on_create validates_presence_of :parent_id, :message => "You must specify a

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. I''d like to validate the form input, and then use rails helpers to automatically populate the form if validations fail.

I''m editing an ActiveRecord object in a session through AJAX, updating it with object.attributes = params[:object], and validating it with object.valid? Because it''s associated with other objects in a form, I want to save them all together. The surprise was that object.valid? triggers after_validation_on_update. I''m having an audit log and I was getting bogus entries.

Hello, I have a situation where an ''employee'' belongs to a ''department'' and have setup the relationship as follows. class Employee < ActiveRecord::Base belongs_to :department, :foregin_key => "department_id" validates_associated :department_id end class Department < ActiveRecord::Base has_many :employees def validate_on_update

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 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

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

I''ve got a form with inputs like user[first_name], user[last_name], etc. When editing the user instead of creating a new one I include a user[id]. I then try and save the object using: user = User.new(params[:user]) user.save() I would *expect* that since I included the user[id] it should do an update and should call validate_on_update. But this doesn''t appear to be the
