I want to be able to do something like this (for example): class Person < ActiveRecord::Base has_many :friends def friends(living_in = :uk) # filter based on parameters here end end Is there any way I can redefine the accessor for an association whilst still being able to get the values? Basically, I''m looking for an equivilent of read_attribute() for associations. --

The problem at hand is how to handle missing (but not required) refs to other objects when working in a view (that was not clear - gimme a minute:-). There has been some discussion of this on the wiki, but I was wondering what others thought about handling this. I have class A that belongs_to class B, and I want to display an attribute of B in the view, so I do something like the following:

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

Hi, Is it possible to override the default accessors that are created by Rails? For instance I had this User object which has the column headings "password" and "salt" in its SQL table. I did manage to override the setter accessor for password by using def password=(new_password), but when I tried doing the same for the reader by using a def password method (to return a

Background: I''m writing a eCommerce application which has a Product model and an Option model, they are setup with a has_and_belongs_to_many relationship. The Product model features the ''base'' attributes of the product and then the shopkeeper *can* add one or more Options that

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.

Hello Railists, I have a piece of Ruby on Rails code that has a complex SQL query (well, not that complex, but as far as I know beyond the ORM capabilities) and for my taste it has too many strings and harcoded values. I''d like to improve it as much as possible, so my question is open ended, what else can I do to improve it? Some particular issues I have - Is there a way to get a table

Hi there, I''d like to choose between an "static" and "dynamic" access of a reference class field, say ''a''. myObj <- getRefClass("Blabla")$new() Static: myObj$a Dynamic: myObj$a.get() where the function retrieves the data from a database (or some other location), stores it to a buffer and

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

I am trying to push some view logic into a helper. The thought is that this is a step towards having the business logic in the helper rather than the view. However, I''m essentially wrapping the checks around an eventual call to date_select(). The problem I''m having is that the application complains that it doesn''t know about date_select(). I''m sure (or

I have a database column storing a duration value as a number of seconds, but I''d like users to be able to see it and edit it as a time value. I am trying to override the default accessor/mutator for the attribute and do the conversions there, using something that looks like: def duration Time.at(self[:duration].to_i).getutc end def duration=(value) self[:duration] = value.to_i

Hiall, I have the following problem: I need to use forms containing collections (i will call them FCC), and I want to construct them dynamically, as I need to deal with quite large forms (more than 600 input fields).
