similar to: Inheriting data from one model to another

Hi all! I have come into a strange issue in Rails that I am hoping someone can shed some light. To make a very long story short, I have been researching how to override ActiveRecord::Base#read_attribute and write_attribute to perform security checks at the model level (influenced by the ModelSecurity generator). Shortly after implementing some code to check this behavior, I began to

Hello all, I''ve been trying to use a facade column but I notice that the form helpers don''t seem to respect the facade. In the following example I''m trying to story the prices as Integer values but present them to the user as decimals. class Product < ActiveRecord::Base def price=(new_price) write_attribute(:price, Float(new_price)*100) end def price

I''ve always wanted to be able to do stuff like this in my functional tests c = customers(:customer_1) c.expects(:great_customer_service) post :service_customer, :id => c.id This of course fails because inside the rails action a different instance of customer is used. Some of the time setting your expectation/stubbing on Customer.any_instance works, but it''s not

On my current project I needed to create a stub that responded correctly to the id message. Here''s the change I put into my copy of head.

Hi all, I was wondering if anybody could help me figure why a view cannot find a method that I defined in another class. I do this in the view: (let''s say index.rhtml) <%= check_box("item_search_page", "method_name") Here, item_search_page is a variable in the view''s controller, which creates a new ItemSearchPage object. And I defined

Hey all, I have a question with using mocha in my tests. In the same test file, I have two tests, <code> def test_a klass.any_instance.stubs(:method_name).returns("something") klass.new.method_name ... end def test_b ... klass.new.method_name ... end </code> where klass is some class when the tests run, test _a passes, but test_b had an error like this:

In my Unit tests, I run into the all-too-common problem of Time.expects(:now) being called by Benchmark before the method is unmocked. Instead of messing around with the teardown order, I decided to modify the Expectation with a new method, .stops_mocking. Here are the changes I use, including a few monkey patches to push relevant objects down to where I want them, all wrapped up in a big ugly

Hi all, I just can''t figure why the view cannot find a method that I defined in another class.

Would really appreciate it if someone could tell me why this is happening: I override ssn method of AR class so I can encrypt/decrypt to/from the db: class Person < ActiveRecord::Base def ssn=(value) write_attribute(:borrower_ssn, Crypto.encrypt(self.encryption_key, value)) write_attribute(:borrower_ssn_final_four, value[5,4]) end def ssn # this begin - rescue can be

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

Could someone explain this? #config/initializers/ar_attributes.rb module ActiveRecord module AttributeMethods alias_method :ar_read_attribute, :read_attribute def read_attribute(attr_name) p "read_override" ar_read_attribute(attr_name) end alias_method :ar_write_attribute, :write_attribute def write_attribute(attr_name, value)

Hey Everyone. First day diving in to ROR and Ruby... My question is how do you define methods with in the model class and/or should I even be doing this? It is my understanding that you should put as much of the business logic into the model as possible. I want to do some data manipulation before I things are submitted to the database IE (Create a variable out of two submitted via form, as

I am using ''redmine'' (v 0.6) as my major project manager, seems running fine w Rails 2.0 (slight modifs for paginations..) but I am stuck with a major error when sending a confirmation email : mailer.rb class Mailer < ActionMailer::Base .... # Renders a message with the corresponding layout def render_message(method_name, body) layout =

I wish to extend ActionMailer::Base by method chaining a class instance variable: module ActionMailer class Base class << self def method_name ... What is the magic incantation to accomplish this? I cannot get this to work with action mailer: module MyMethods def self.include(base) base.alias_method_chain :method_name, :my_method def

When a column in a database table is actual data, rather than an fkey to another table, I can override the automatic accessor by just doing the following: def field_name # do something here read_attribute(field_name) end This does not seem to work for me if the field is an fkey, say user_id, linking to another table. I''ve made this work by aliasing the accessor like this: alias

I''m learning rails and have a test application which parses parts an XML file to create AR objects and puts them in a database. The IDs in the database are taken from the XML, i.e. I explicitly set them using #id. The XML structure is mapped to AR relationships using has_many, belongs_to etc. I''m using a SAX parser, creating objects when the element start tag occurs and saving

All, I''m having a hell of a time figuring out what is going on here. I''m trying to override one of my getters so that I can format it a certain way in my form. But I can''t seem to get text_field to call the appropriate method on my object. So here''s my getter: public def FAX fax = read_attribute(:FAX) puts fax

I recently needed the behavior of my object to change on subsequent method calls so I added the syntax above.
