similar to: validates_presence_of fields. in parent ok, but how in children?

What are the limitations on using: errors.add_to_base to display errors in views? I have tried for days to add errors from my object.rb and they never get displayed. class Keyword < ActiveRecord::Base validates_presence_of(:name, :message => "Name is required.") validates_uniqueness_of(:name, :message => "This name is already in use. Please try

Thanks (everyone) for the suggestions, they were helpful. What I decided to do was to essentially "wrap" LLVM's BasicBlock structure with my own block class that contains additional high-level information. Up to this point I was generating LLVM basic blocks on the fly as I walked the statement tree; Now I build my own BB graph, and then use that to generate the BB graph for

In the language I am working on, there are cases where the call flow graph can affect the type of a variable. A simple example is a "nullable" type (a pointer which is allowed to be NULL), which can be converted into a non-nullable type via an if-test. So for example if x is nullable, and I test x != NULL, then inside the conditional block the type of x is no longer nullable.

Hi, I want to show a series of links belonging to a specific category. The links will be shown grouped by category, but how can I alter the order of the categories? I have a field in my database called position with the order in which they should appear.

Ok, I have read most of Agile Web Dev... so I had a question about beautifying URLs using routes.rb. I''m trying to architect a content management system in which a user can create template pages. This way, when a user creates a template page nested within, it displays it as though it''s displaying a folder structure, much like a directory tree (using acts_as_tree). I have a

I''m trying to write my first view spec; I''ve done some controller specs with integrated views, but thought that isolating the views for some of these tests might be nice. So I wrote this: > describe PlayerContainer, "show" do > > PARENT_ID = 12 > CHILD_NAME = ''Child Name'' > PARENT_NAME = ''Parent Name'' > >

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

Hello all. I don''t know how to get all symbols passed to method validates_presence_of in model. I''ve trying to use following solution: class News < ActiveRecord::Base validates_presence_of :title, :text def validates_presence_of(*attr_names) @@obligatory_fields = attr_names ActiveRecord::Base.validates_presence_of(*attr_names) end def obligatory_fields

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 trying to get to happen is if one is there they all must be

Hi, I am trying to use method `validates_presence_of'' for validating my input fields on form . I m using it in my action class as follows:- ======================= validates_presence_of(params[:product][:quantity]) ====================== But when I am running my application i m getting error like:- ========================= undefined method `validates_presence_of'' for

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

Suppose: class articles < ActiveRecord::Base has_many :assistarticles validates_presence_of :body end class assistarticles < ActiveRecord::Base belongs_to :article validates_presence_of :detail end In the submit form: <%= text_field ''article'', ''body'' %> <%= text_field ''assistarticle'', ''detail''

Hi all, I want to submit the content of a form by mail. I don''t want to save it into a DB. How can I validates the content of this form with validates_presence_of ? Thank you. Damien

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

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

I''m having what''s probably a stupid-newbie problem with validates_presence_of and I''m hoping someone will point me in the right direction. Bottom line is that validates_presence_of does not seem to be ''firing'' when I use the :on => :update option. If I don''t include the option, the validation does fire. The problem is that I want to

Hi. I have "validates_presence_of :login, :password, :firstname, :lastname" in my user-model.
