similar to: Getter and Setter with non DB property

Hi, I have some problems with an application where I''m using custom accessors to do currency conversions. In my model, I have a price attribute in the database that stores the value in cents, to avoid future problems with float arithmetic and round. But at the views, I would like to show the price in euros, with decimal for the cents. So I defined a new attribute called price_in_euros,

Rails extends Ruby with mattr_accessor (Module accessor). As Ruby''s attr_accessor generates getter/setter methods for instances, mattr_accessor provide getter/setter methods at the module level. In below example, you see that mattr_accessor declared in the class context of LookupContext. It''s declared in class, not module. However, modules are defined in LookupContext, for

Hey.. So I have a model that has a lot of number fields. Each of these go through a process when read in and read out to add/remove commas (between every three numbers) to make them more readable. The getter I currently have is like this: def sale_price Listing.insert_commas(read_attribte (:sale_price)) end and the setter is: def sale_price=(price) write_attribute(:saleprice,

Hi list, first evening of playing with rails, so please forgive me if I ask something stupid. ;-) I created a User model and tried to use ActiveRecord callbacks to convert the password to sha1 just before saving it. For some reason postgresql gives me a error because the given password is null. To test even further I tried to change :login too, same error happens, :login is empty too. I am sure

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

Hi everyone, just wanted to ask what's the smartest/recommended way of defining getter and setter function *shortcuts* (i.e. something like "[", "[<-") for Reference Class objects? Or is it desired to not use this stuff, but define methods like 'obj$getSubset(row=1:3, col=1)' and 'obj$setSubset(value=x)' instead? I have some example code that might

This may be a dumb noob issue, but I haven''t found any answers while seaching the forum-- I have a controller method def edit @user = User.find params[:id] @user.password_confirmation = @user.password end The User class has an "attr_accessor :password_confirmation" definition (so "password_confirmation" doesn''t exist in the users table). My spec

Studying the RoR 3 Tutorial book by Michael Hartl and on page 345 there''s the code inside the SessionsHelper: _________________________________________________________ module SessionsHelper def sign_in(user) cookies.permanent.signed[:remember_token] = [user.id, user.sault] self.current_user = user end end __________________________________________________________ What is the purpose

Hi, What''s the difference between attr_accessor and attr_accessible? Is attr_accessor to create a virtual variable/object and attr_accessible makes it accessible? Do you need attr_accessible if you already have attr_accessor?

In my project I have a group of foreign types (C++ classes) that I want to use, but don't want to represent as structs within LLVM. For example, for each field in each C++ class I have a setter and getter function that I'd like to use. The setters and getters are "extern C" functions to avoid problems with C++'s name mangling. After going over the documentation it

I have a field called Fax in my model. I store it as a 10-digit number with no other characters but I display it as a nicely formatted phone number. I have a validation on it like this: validates_format_of :Fax, :message => ''number should be formatted using (XXX) XXX-XXXX'', :with => /^\(\d{3}\)\ ?\d{3}-\d{4}$/ If I put 1234567890 (10 digits) in my field, the

Hi, I have a AR model that I want to limit changes to be only via instance methods that I''ve added. How do I prevent my other sw from setting the instance''s attributes? I know about #attr_protected and #attr_readonly. But the first leaves the individual setters as they were and the second stops all changes. I want something like "attr_private" Thoughts? Thanks,

Im developing a User model for my application (newbie stuff, but I have to start somewhere). I followed the tutorial at http://sonjayatandon.com/05-2006/how-to-build-a-secured-web-application-with-ruby-on-rails/ and decided to add an email field. The problem is that the email is not being saved on the database and I end up with two email variables: @email and email. validates_presence_of

Hey everyone, I am developing a package and I am wondering if there is a good practice for naming classes, builders, attributes getters and setters when dealing with object composition. I know that it is usually a good practice to give to the builder the same name as the class and, if possible, to avoid to use upper case letters. My problem is that, when I build an object containing an other

I have some properties that I want setable externally, but readable only internally. I''ve played around with attr_writer (and attr_reader separately) but can''t figure out how to get either to work. I can do what I want using attr_accessor, or just straight out defining the prop setter method. Anybody know how to use attr_writer or attr_reader with a model? You da man, Joe
