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

Greetings, I have a partial template file (acutally, it is an RJS file but the same principle is in question here) which I wish to "share" between multiple controllers. Does anyone know where in the directory tree I would put these files in order that I can access them from multiple controllers in the same app? I really would prefer not having to copy them all into all of the

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?

Is it possible to use the calculate methods (sum, etc.) on attr_accessor attributes?

Hi, I''ve got a model with the following attribute added: attr_accessor :level which does not exist in the database. After putting instances of this model in the cache (using Rails.cache.fetch(''foo'') { Category.all } ), when I retrieve it back from the cache, then trying to access .level gives: undefined method `level'' for #<Category:0x34d50a0>

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

Please guide me how to use those two methods. I can''t differentiate them. I was doing something on my model and I have put one field in the attr_accessible method. After that when I try to run the app the app always says my other fields are blank, but they''re all filled up. What''s wrong with it?

i''m very new to the rails scene and am seeing lines of code like attr_reader, attr_writer, attr_accessor, etc... and have no idea what they do. reading the section in the book i''m reading that explains the previous block of code says nothing about it really. -- Posted via http://www.ruby-forum.com/.

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

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,

In console, I am trying to create a User but the :account_id does not come in. Console just gives me back :account_id => nil. Obviously I''m trying to set it though. Silly console... But, I can set the account_id column in my controller like so: @user = User.new(params[:user]) @user.account_id = account.id @user.save Here''s what I give to the controller: User.create :name

i''m having trouble understanding the attr_accessor and attr_accessible syntax in models. I''m workink through the Agile book and even a look at the ruby doc does not really help to clarify. Thanks aftershock -- Posted via http://www.ruby-forum.com/.

I have more or less the same problem. I''m trying to build a system where users can enter their friends. But the solutions seems not to work for me. I used same sql: CREATE TABLE `friends` ( `user_id` int(11) NOT NULL default ''0'', `friend_id` int(11) NOT NULL default ''0'', KEY `user_id` (`user_id`), KEY `friend_id` (`friend_id`),

Hi, I think at first you have to do a net groupmap add all the well known Groups.

I am trying to replicate part of the function of the S-Plus terms.inner function. I don't need an entire model terms object but R expressions or character strings containing the innermost variable name given a vector of character strings or expressions. Here are some example inputs that each should result in the string or expression "x": x; x^2; g(x); h(g(x)); h(g(x^3));

Hi, i''ve been playing with ror for a little over two months now, and was wondering wether someone could explain to me what was cattr_accessor and if it is still in use. . . i looked up in api.rubyonrails.com and coulnd''t find any documentation... is it a useful/worth learning method? what do u use it for? -- Posted via http://www.ruby-forum.com/.
