similar to: Weirdness with validates_presence_of

This almost feels like a bug to me, since false is not nil. (i don''t think!) Using v_p_o on a boolean field fails validation if the field is passed with ''false''. It passes validation in the case of true. How can I validate _presence_of a boolean if it is submitted false? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~

i have a person object. Persons don''t need to have addresses, but if they have any address field value, they must have them all.

Category.has_many :products Let''s say a product must belong to a category. I know it is recommended to do the following: class Product validates_presence_of :category_id end But, as we all know, this is a pain for new records, meaning what if the associated category is a new record? I''ve been meaning to ask this, but what''s wrong with doing the following: class

I am just going through the book and I come across a problem with the code in the app/models: validates_format_of :image_url, :with => %r{^http:.+\.(gif|jpg|png)$}i, :message => "must be a URL for a GIF, JPG, or PNG image" It seems to moan when it''s empty even though I removed :image_url from validates_presence_of. How should I make it optional?

Anyone got any idea of how to use built-in validation methods in a mixed-in module. What I''ve got at the moment is each class that needs ranking methods includes [the module] Ranking. Then the module Ranking has a bunch of instance methods and a submodule ClassMethods. The ClassMethods in this are mixed in to the class with self.included. So far so good. But I want the module to

I have a model that contains a :boolean field. In my view, I have a simple select of Yes or No, which equates to true or false, respectively. If I choose yes and save, everything works great. If I choose no, my model fails validation as I have this set as a required field using validates_presence_of. I have checked the log and it''s definitely set to false, why would this fail validation?
