Any help will be apreciated, thank...

I have a form with 3 fields: user_id, email and password. All 3 fields are required, so I have a "validates_presence_of :user_id, :email, :password" in my model. Works, but the validation errors show up in a different order than I specificed in the validates_presence_of statement. Is there a way to specify the order in which the validations (and corresponding error messages) should occur using the built in...

Hi, I have a call to validates_presence_of in my model and it is behaving very strangely my first stab when this happened during testing was validates_presence_of :impact, :ease_to_implement if Proc.new { |record| !record.cost_estimate.nil? } I have three values in my model that I care about with this one. Basically what I''m tr...

...y 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 parent for this keyword." end and I get: undefined method `validates_presence_of'' for #<Keyword:0xb774aba0> The only time it works is if I remove validate_on_create, but then I can no longer update existing entries t...

validates_presence_of :fname results in the error message "Fname can''t be blank". What I want is "First Name can''t be blank". I could do this def validate errors.add_to_base("First Name can''t be blank") if fname.blank? end I find this clunky and I have to...

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. So I have something like this: validates_presence_of :street_address, :city, :state, :postal_code unless :address_blank? address_blank? checks whether all of the address fields are blank. If I run a test like this, it works: describe "given attributes" do before(:each) do @valid_attributes = { :first_name => "...

...s 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 contain some validation definitions (using the built in methods validates_presence_of etc) for the classes that are mixin it in. Have tried putting them in the ClassMethods and the instance methods, and both throw up NoMethodError when I start up the console. Anyone able to help?

...me 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? Altering the regex? Btw I have the same sort of problem with example code for the price example. I want it optional unless I used validates_presence_of. Isn''t that sensible? In the SQL DDL, does NOT NULL mean anything here?

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 Product validates_presence_of :category end I never understood why tha...

If I have belongs_to :user Do I need to have validates_presence_of :user_id ? Does Rails validate the presence of :user_id automatically if I have belongs_to :user? In other words, does Rails prevent against creating orphan records that belong to non-existent users? Thanks. -- Posted via http://www.ruby-forum.com/.

I''m in the process of creating a sign up form for an online application. The form collects account info, company info, and then info for an administrative user. The method looks like this: def create @account = Account.create!(params[:account]) @company = @account.companies.create!(params[:company]) @user = @company.users.create!(params[:user]) end However, this inevitably fails

I''m getting some weird behavior in one of my models. I have a model defined something like this class User < ActiveRecord::Base attr_accessor :password validates_presence_of :password end If I validate the model without specifying a password, I get ["can''t be blank", "can''t be blank"] for :password instead of just one "cant''t be blank". If I comment out the validates_presence_of statement, then no errors. So it...
