I have a Product model and products table. Im using acts_as_tree structure. I would like active record validation to be done on children only. Anyway to do this?

Anyway to do this?The root product is the product who has no parent. So in your validation, you could pass an :if option and a condition in the block : :if => Proc.new { |r| r.parent } Example : validates_presence_of :name, :if => Proc.new { |r| r.parent } -- Jean-François. -- À la renverse. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hello Petr,
I think this can be done.
Here provided an example were a validation runs only for certain
customer types.
validates_presence_of :birthday,
:street,
:street_number,
:zip_code,
:city,
:bank_name,
:bank_code,
:bank_account,
:telefon_number,
:message => "darf nicht leer sein.",
:if => Proc.new { | customer |
customer.customer_type.name == "partner" or
customer.customer_type.name
== "customer" }
The important part for you is the :if part. Only for object that pass
the test in the Proc the validation is used.
There is a "has_parent?" method for act_as_tree objects. I think this
could be used for your problem...
Feurio

Hey, thanks. I have one more question, could you describe to me what that does in detail? I know Proc objects from Ruby, I just cant imagine how it works in this case.

Hello Feurio,> There is a "has_parent?" method for act_as_tree objects. I think this > could be used for your problem...acts_as_tree defines a belongs_to association named 'parent', so you can benefit from a #has_parent? method. However this method is deprecated and you should use #parent (that is, the method with the name of the association), if there is no associated record, it returns nil then in a condition it will be false so you can use it. Note that if you have a has_many :foos association, #has_foos? is also deprecated. -- Jean-François. -- À la renverse. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
