Hello all. I have a problem using validates_inclusion_of. I need to switch off some validations during a migration period, is there a way? I tried to use if, with a static method of one of my models, but the behaviour is something strange It seems that the static method should be in a string to be evaluated. And the order of the elements in the if is counting... :if => (:some_field && ''MyModel.some_static_stuff'' ) -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Re: validates_inclusion_of disabling
Yeah, no answers in 4 hours! Rails must suck! I don''t know what you are trying to do. Are you trying to turn off conditions based on a particular condition? I.E. "If a user submits from form A then validate, if a user submits from form B then don''t validate" ?

Sorry for the stress Andrew, but in my last posts I didn''t get any answers. I''m trying to turn off validations based on config. I have a constant that tells me if I''m runnig a migration, and if I do, some validations should be turned of.

http://api.rubyonrails.org/classes/ActiveRecord/Validations/ClassMethods.html#M000940
That link will tell you how to set up a :if statement on a validation.
Basically, the :if should be a string (which will be run through an eval), a
function (via it''s symbol name), or a Proc... whichever of the 3 it is,
it
should return true or false when evaluated.
validates_inclusion_of :test, :if => ":some_field &&
MyModel.some_static_stuff"
or
validates_inclusion_of :test, :if => :is_migration?
def is_migration?
:some_field && MyModel.some_static_stuff"
end
or even
validates_inclusion_of :test, :if => Proc.new { :some_field &&
MyModel.some_static_stuff }
If your requirements might change (you might add to or take away from the
conditions), you''d be best off going with a function, if it''s
VERY simple
stuff (like what you have here) and it will never change, use a string. If
you need access to the particularly object that the validation is being
called on, you can use a proc (or a function) that accepts an argument...
validates_inclusion_of :name, :if => Proc.new { |user|
user.should_have_name? }

Well, it should be simple...
My reality:
In env[...].rb: MIGRATING = false
In My model:
def self.validate
return !MIGRATING
end
And the use of the if statement...
validates_inclusion_of :objective, :in => Range.new(Date.today,
Date.new(y=4712)), :if => ":objective &&
Requirement.validate_on_mig"
,:message => "bla bla bla"
Does not work :(

What is the :objective check in the :if supposed to be doing? What is the validate_on_mig function doing? I don''t see you calling the self.perform_validation from anywhere, is it necessary?

And the self.perform_validation it''s beeing called in the :if, by Requirement.perform_validation The correct validations is: validates_inclusion_of :objective, :in => Range.new(Date.today, Date.new(y=4712)), :if => ":objective && Requirement.validatevalidation _mig" ,:message => "bla bla bla" -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

If you absolutely HAVE to have that in there, I would change the :if to :if => Proc.new { |m| m.objective && Requirement.perform_validation } I still have absolutely no clue where that whole validatevalidation_mig stuff is coming from... but I''m pretty sure what I said is what you''re looking for. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I have the validation of the fieldin the if statement because i wan''t to validate if the field is in the correct Range if the user inserts something, if he does not, the message is different... that validation_on mig is the Requirement.perform_validation... I changed the method name... sorry for the mess..., I''m gonna try with Proc.new...

Luke, you''re absolutely right! It works fine! If I change in my config the MIGRATION to false, the validations is performed!
