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

Hi, The following patches are just copying some functionality that exists in the asm cmdline code into the C version. There's still a few more things to do but we're getting there. The following changes since commit 8c576f1fe03e34879921311f46613a35c6530000: Merge remote-tracking branch 'mfleming/for-hpa/elflink/fix-compiler-warnings' into elflink (2011-03-16 12:53:58 -0700)

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.

Hi to everyone, My name''s Carmine and I''m a rails newbie. So, here''s my newbie question :) I have a model with one attribute named "kind" of type integer. This attribute can assume values within the range [0..5]. Each value has a "verbose" representation e.g.: 0 => grain, 1 => liquid ... To visualize the verbose representation I''ve

- MODEL - class Document < ActiveRecord::Base has_one :user, :class_name => "User", :foreign_key => "fkey", :conditions => "user = ''NAME''" end - GENERATED SQL (per the .log) - SELECT FIRST 1 * FROM table_name WHERE (table_name.fkey IS NULL AND (user_id = ''NAME'')) What I can''t figure out is

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

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)

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

Anyone know how to send a file/data to the user agent (download it) using #send_file or #send_data, *and* render a new page in the same action? This just sends the file and doesn''t render the page: def gimme ... send_data(our_data, :filename => ''output.csv'', :disposition => ''attachment'') end And this will give a Double-Render error:

Hi all, here is the challenge: I have this validation method, that basically prevents an object which billed = true to be updated: def before_update if read_attribute(:billed) errors.add_to_base(''This service has already been billed for'') end !read_attribute(:billed) end The above code does not work in case I do something like: object =

Hello List, I''m a bit spent on this problem, and my code might be whack. I seem to be encountering a problem where the primary key on a join table is not being resolved correctly. I will elaborate after some code bits. I am creating the join table using migrations, and relevant model code is this: class Post < ActiveRecord::Base has_and_belongs_to_many :records

Guys, Say I have the following: ----- class Person < ActiveRecord::Base has_one :house end class House < ActiveRecord::Base belongs_to :person attr_accessor :color end ----- Then I have the following code: ----- john = Person.new john.house.color = "Blue" john.save ----- What I would like to have happen, is that on first call to john.house, if house hadn''t been

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, Is there a better way to do the following in a view? <td>Manufacturer <td><%= @equipment.manufacturer.name unless @equipment.manufacturer.nil? %> -- Posted via http://www.ruby-forum.com/.

Hello I''ve been struggling with something for hours that I thought would be a simple job. Hopefully somebody can shed some light on what I''m trying to do :o) First of all I''ll explain what I''m trying to achieve. In a store application I want to have products and product variations.

Hi, I''m building a frontend for a legacy schema, with tables like this: CREATE TABLE `types` ( `a_type_cd` varchar(6) NOT NULL default '''', `a_type` varchar(30) NOT NULL default '''', PRIMARY KEY (`a_type_cd`) ); The primary key is specified by the user (not auto-generated), and needs to be updateable.
