Say I want to gather info from various Models... Files, Folders, and put them into a ''display'' Object DisplayFilesystem that will standarize the info from both tables (for display only)...

In rhtml, you have access to controller. I am trying to set an instance var in my controller, then retrieve it in my form display. I know I could do this through one of the hashes I have access to, but I''m trying to understand why I can''t do it this way. No matter what, when I try to output from my rhtml either <%= controller.whynot || ''Unknown'' %> or

I have a model named Project which contains a name attribute, and I have a second model named Booking which has, among other things, a date and a Project. (has_many :bookings, belongs_to :project). When a user creates a new Booking, they have the option of using an existing Project or creating a new Project. As an added complexity, when choosing from existing Projects, they can either choose from

I have an error I don''t know how to debug. I am adding the login suport in Depot (the example in the RoR book) and LoginController#add_user throws ActiveRecord::StatementInvalid in an innocent /login/add_user GET request. The trace goes down to a call to SQLiteAdapter#table_structure, and the source code suggests what''s happening is that "PRAGMA

Hi all, I''ve been struggling with this problem for the past 2 days and still haven''t found a good solution - any help would be appreciated! I have a ''list'' page that lists all products from a DB. On top of that listing I have a little box where the user can specify ''filter'' parameters (eg, book name equals ''foo''). The

I am serializing a data object (FooData) into an ActiveRecord column (Foo). I''d like to be able to do delegate methods to the data class if the Foo class doesn''t have that attribute. So instead of: f = Foo.new f.data.item1 I''d like to do: f = Foo.new f.item1 I was hoping that I could add a method_missing method to my Foo class and call methods in the FooData class

Hi, I''ve a model that is stored to the db, but just one of its atribbutes doesn''t have a corresponding column on the table (it is used just for a calculation and still requires validation).

Hi to all, I have this error and I don''t understand why. I have three model, Image and Playlist and PlaylistItem. Everything works fine. The app should work also a XML REST service.

Hi! Well, I thought this was easy, but for some reason it won''t work... Here is what I want to do: I am working on an API to a large database. The basic mapping is done, but I want to implement some convenience methods that take information for one object and does some calculations with it. The result should be accessible as attribute. So in a simple example: We have an object that

In a form_for context, is there a way to access objects that are related to the primary object with a belongs_to? I think an example will serve best: class User < ActiveRecord::Base belongs_to :person attr_accessor :username end class Person < ActiveRecord::Base has_one :user attr_accessor :first_name end <% form_for :user do |form| %> <%= form.text_field

I have a model that looks like this (with various other methods) class HsdPair attr_accessor :hsd def initialize(hsd) @hsd = hsd @current_display = 0 @has_changed_flag = false end end After initializing this object in the controller @hsd_pairs = HsdPair.new(@job.hsd_pairs) using it in the view various times and in various ways, when I try to pass this object back to the

<pre> models/user.rb: # Oops! I forgot to add the :password_confirmation attribute! class User < ActiveRecord::Base attr_accessor :password attr_accessible :password #, :password_confirmation validates(:password, :confirmation => true, :presence => true) end activemodel/lib/active_model/validations/confirmation.rb: 3 # == Active Model

I''ve been trying unsuccessfully for the better part of today to write a worker that can use by ActiveRecord model classes. The bizarre thing is that worker just stops at the point accessing the database connection. An exception isn''t raising, it just dies. My worker class is below, I''ve interspersed log messages throughout to try to determine where it is dying. =====

Trying to do some error handling a la AWDWR and trying to manipulate the errors collection in a model object. But there isn''t an errors attribute in ActiveRecord anymore it seems. Is there still a handy way to specific model validation errors in a built-in container? Thanks, Wes -- Posted via http://www.ruby-forum.com/.

Here is the setup: A simple class representing a US State (say, Maine for example): class State < ActiveRecord::Base attr_accessor(:name, :code) end In an IRB session, I type the following and receive the response included below: >>

When submitting billing information in the past I''ve always used attr_accessor for credit card details as they should not be saved in the database. In addition I always end up storing the card expiration date so that the date form helper works correctly. With Active Model it seems logical to create a CreditCard class to hold this data instead. **1st issue.** It seems there still

Is it possible to use the calculate methods (sum, etc.) on attr_accessor attributes? Ie: Class Item < ActiveRecord::Base attr_accessor :total_cost def total_cost @total_cost = self.cost_unit * self.amount end calling Item.sum(:total_cost) or Item.sum(''total_cost'') both return a unknown column ''total_cost'' mysql error.
