Working through the beginning phase from the Agile book on ''Administration'' undefined method `hashed_password='' for #<User:0xb7911324> ... /usr/lib/ruby/gems/1.8/gems/activerecord-1.13.2/lib/active_record/base.rb:1498:in `method_missing'' #{RAILS_ROOT}/app/models/user.rb:12:in `before_create''

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

I''m trying to follow along with the Agile Development with Ruby on Rails book and have encountered a problem with code having the following syntax (partial class provided): require "digest/sha1" class User < ActiveRecord::Base private def self.hash_password(password) Digest:SHA1.hexdigest(password) end end I''m getting an error as: undefined method

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

Hi! There''s something I don''t understand yet about static/private methods. I hope someone can explain... E.g.: class SayHello def hello(who) puts "Hello, " + who + "!" end def self.say(words) puts words end end hello = SayHello.new hello.hello "World" : Hello World! hello.say "hi" : Error SayHello.say

Happy New Year everyone. Just wondering if anyone has coded the ability to allow a user to change their password following the way the book (second edition) implements administration. Seems like I should be able to cut out the password/password_confirmation portion of ''add_user'' form to create a ''change_pass'' form. The problem is I''m not sure how to go

I have an error I don''t know how to debug. I am adding the login suport in Depot (the example in the RoR book) and LoginController#add_user throws ActiveRecord::StatementInvalid in an innocent /login/add_user GET request. The trace goes down to a call to SQLiteAdapter#table_structure, and the source code suggests what''s happening is that "PRAGMA

Hi all, Is there a way to invoke validations at times other than save, create and update? I know that I can do this by writing my own validation checks using errors.add_[blah], but I''d like to leverage the existing validation code. What I have is two sets of fields in a record, set A and set B. Both sets must be validated on record create. However, the trouble is that after

Is there an addition to the Rails Recipe or the method in AWDWR to allow a user to change his/ her password? I have put something together that does all the work again - mostly because I''m not sure how to leverage on methods like ''password='' that are defined in the model. Has anyone got a ready sample that I could learn from? Right now, I''m basically

I''ve got a User model, which holds the following (excerpt): def try_to_authenticate User.authenticate(self.username, self.password) end .. private def self.hash_password(password) Digest::SHA1.hexdigest(password) end def self.authenticate(username, password) @user = User.find(:all, :conditions => ["username = ? AND password = ?",

I had a couple comments on my proposal to write a how-to on NVIDIA on Xen Dom0: Marcus: I would rather prefer if you could take care of the current Xen articles on the wiki, first. They are quite outdated. --- I don't consider myself an expert on all things Xen. In reviewing the material on the CentOS Wiki regarding Xen, I felt the articles were pretty well done (even if they were

I''m having a problem redefining a method in one of my modules. Lets say I have this module in /lib: module Hello def say_hello "hello" end end And one of my ActiveRecord models mixes it in like: class Item < ActiveRecord::Base include Hello end This works fine, I can call @item.say_hello just fine. But when I try to redefine the method: class Item <

Hi, I am quite new to rails and can''t use any rjs-templates. The problem is, that he can''t use/find the methods in that template e.g. ''page'' or ''replace_html''. I get an error message on these methods. Here''s what I got so far in my example: Controller: ---- class AjaxTestController < ApplicationController layout

Hi, If I want to have helper method for my rjs, where''s the best place to put it? so for example: --- bla.rjs: page.replace_html ... page.visual_effect ... --- somewhere: (currently I put in application_helper.rb) def replace_with_effect(page) page.replace_html ... page.visual_effect ... end --- bla.rjs: replace_with_effect page and is there a way to define the helper so we

Say the user first enters "ruby" for search and gets 1000 results. Then he can search "rails" just in the 1000 results just returned. The common scenario is some kind of advanced search.
