Validations in the same Model

Hi all,

I am newbie in Rails and new at this group. I am with a problem with
validation. I searched at Google but I cant see anything.

I have just one Model: User. I have 2 CRUD''s (controllers and views):
Representatives and Users... Users CRUD is ok but Representatives not.
I have different validations rules for Representatives and Users, but
I have to use the same table in the DB, so the same Model.

How can I make different validations in a same Model?

Thanks a lot!

Look into STI (single table inheritance).  This will let you use the same
underlying table (and share common functionality) among multiple models...

Re: Validations in the same Model

Hi philip!!!

Thanks for your reply. I read about STI and solve my problem.

BUT now I have another hehe. I have 2 validations rules, because I
have a has_one association. How can I do this?

http://pastie.org/1836266

For example... I have to validate :name (Profile) for Representative,
but not for User.

Thanks!

class Profile...

validates :name, :presence => {:if => lambda {|p|
p.representive.present?}}

end

Or something like that... might need to check the class type instead... that
should get you started though.

Re: Validations in the same Model

Just to complete the topic... solved!

Solution:

validates_presence_of :name, :tel_commercial, :tel_mobile, :address, :city,
:state, :neighborhood,
                        :if => :representative?

  def representative?
    lambda {|p| p.representative.present?}
  end

Thanks philip! []s
