• I get an Exception when trying to implement reset password with Authlogic

  - by Tam

  Hi, I'm using Ruby on Rails 2.3.5 and Ruby 1.9 and implmeneted Authlogic as my authentication engine. Authlogic works fine. But now I have been trying to implement password reset using the following tutorial: http://www.binarylogic.com/2008/11/16/tutorial-reset-passwords-with-authlogic/ But I'm getting the following exception when I type mysite.com/password_resets/new Processing PasswordResetsController#new (for 127.0.0.1 at 2010-03-13 01:09:45) [GET] Completed in 9ms (DB: 0) | 200 [http://localhost/password_resets/new] [2010-03-13 01:09:45] ERROR TypeError: can't convert Array into String /Users/tammam56/.rvm/gems/ruby-1.9.1-p378/gems/activesupport-2.3.5/lib/active_support/core_ext/string/output_safety.rb:34:in `concat' /Users/tammam56/.rvm/gems/ruby-1.9.1-p378/gems/activesupport-2.3.5/lib/active_support/core_ext/string/output_safety.rb:34:in `concat_with_safety' /Users/tammam56/.rvm/gems/ruby-1.9.1-p378/gems/rack-1.0.1/lib/rack/handler/webrick.rb:63:in `block in service' /Users/tammam56/.rvm/gems/ruby-1.9.1-p378/gems/actionpack-2.3.5/lib/action_controller/response.rb:158:in `each' /Users/tammam56/.rvm/gems/ruby-1.9.1-p378/gems/actionpack-2.3.5/lib/action_controller/response.rb:158:in `each' /Users/tammam56/.rvm/gems/ruby-1.9.1-p378/gems/actionpack-2.3.5/lib/action_controller/string_coercion.rb:16:in `send' /Users/tammam56/.rvm/gems/ruby-1.9.1-p378/gems/actionpack-2.3.5/lib/action_controller/string_coercion.rb:16:in `method_missing' /Users/tammam56/.rvm/gems/ruby-1.9.1-p378/gems/actionpack-2.3.5/lib/action_controller/reloader.rb:22:in `method_missing' /Users/tammam56/.rvm/gems/ruby-1.9.1-p378/gems/rack-1.0.1/lib/rack/handler/webrick.rb:62:in `service' /Users/tammam56/.rvm/rubies/ruby-1.9.1-p378/lib/ruby/1.9.1/webrick/httpserver.rb:111:in `service' /Users/tammam56/.rvm/rubies/ruby-1.9.1-p378/lib/ruby/1.9.1/webrick/httpserver.rb:70:in `run' /Users/tammam56/.rvm/rubies/ruby-1.9.1-p378/lib/ruby/1.9.1/webrick/server.rb:183:in `block in start_thread' Honestly I'm not sure where to start debugging for this. Is it because I'm using Ruby 1.9? some people seem to be having trouble with Authlogic and Ruby 1.9: http://isitruby19.com/authlogic Please advise me how to go about solving/debugging this issues? Thanks, Tam

• action mailer gem and tlsmail gem not working in heroku after GIT PUSH HEROKU

  - by user163352

  I'm using heroku as my host..It was working fine. Then I installed action_mailer_tls and tlsmail. Then I comitted it and pushed it heroku.. After that I got error in myapp.heroku.com.

• Ruby on Rails - How to migrate code from float to decimal?

  - by user1723110

  So I've got a ruby on rails code which use float a lot (lots of "to_f"). It uses a database with some numbers also stored as "float" type. I would like to migrate this code and the database to decimal only. Is it as simple as migrating the database columns to decimal (adding a decimal column, copying float column to decimal one, deleting float column, renaming decimal column to old float column name), and replacing "to_f" with "to_d" in the code? Or do I need to do more than that? Thanks a lot everyone Raphael

• Rails Message This User Button

  - by bob

  Hello, I am using this http://github.com/professionalnerd/simple-private-messages plugin in rails and I am on a user page show.html.erb - User and I want to put a button there that, when clicked, goes to the current user's inbox and populates the field call "send to" with the "user" name. How do I send that data along when the button is clicked? <%= link_to image_tag('send_message_button.jpg', :title => 'send #{user} a message', :alt => 'send #{user} a message'), new_user_message_path(current_user), :class=>'messageuser' %> This goes to the current_user's inbox. I want to send the "params[:user_id]" variable along with it so that I can then fill out the "send to" textbox in the inbox page with it. How do I send that params variable along with this button?

• Formtastic nested model form fields (Rails 3)

  - by elsurudo

  So here's the scenario: User: has_one :company accepts_nested_attributes_for :company Controller: @user = User.new @user.build_company View: <% semantic_form_for @user, :url => register_path do |form| %> <h2>User Information</h2> <%= form.inputs %> <h2>Company Information</h2> <% form.semantic_fields_for :company do |company| %> <%= company.inputs %> <% end %> <%= form.buttons %> <% end %> After scouring the web, this SEEMS like it should work. However, all I get are the user inputs. The "semantic_fields_for :company" block outputs nothing at all... Am I missing something here, or is this perhaps a Rails 3 bug to do with Formtastic?

• Rails ActionMailer problems on Mac

  - by seth

  I've been working on learning to use Rails the last couple days and I've run into something that I haven't been able to solve with Google. So I'm just creating a basic contact form that sends an email. Everything seems to be working ok in testing, which tells me that the form is working, and ActionMailer was implemented correctly, however, I'm having trouble configuring ActionMailer. I'm running OSX 10.6.2. I have postfix running and have verified that it's running using telnet localhost 25. When I try to use the form I get a "Connection refused" error. This is my current configuration: config.action_mailer.smtp_settings = { :address => 'localhost', :port => 25 } I thought I might need to set :domain but I'm kind of confused on what that should be set to in this situation.

• MongoMapper, Rails, Increment Works in Console but not Controller

  - by Michael Waxman

  I'm using mongo_mapper 0.7.5 and rails 2.3.8, and I have an instance method that works in my console, but not in the controller of my actual app. I have no idea why this is. #controller if @friendship.save user1.add_friend(user2) ... #model ... key :friends_count, Integer, :default => 0 key :followers_count, Integer, :default => 0 def add_friend(user) ... self.increment(:friends_count => 1) user.increment(:followers_count => 1) true end And this works in the console, but in the controller it does not change the follower count, only the friends count. What gives? The only thing I can even think of is that the way that I'm passing the user in is the problem, but I'm not sure how to fix it.

• Rails Foreign key setup question.

  - by James P. Wright

  I'm just (re)starting playing around with Rails and I'm making a little card game app. I cannot seem to figure out my Foreign Key setups. Say I have 4 objects: - Game - Player - Hand - Card A Game has many Players, which have many Hands which have many Cards. But the cards are also independent of a Hand, Player and Game. For example, I have 6 Cards in my database (1 to 6). It is possible that Card 3 could be in 2 Players Hands in the same Game. How can I set up my keys for this? Should I just create another object for "CardInHand" to simplify it?

• Rails 2.3.x, named_scope chaining with INNER JOIN complication

  - by randombits

  I have two hypothetical classes, Foo and Bar. Foo contains many Bars. Bar can only belong to one Foo. Ultimately the SQL query I'm trying to make happen looks like the following: SELECT * from bar INNER JOIN foo ON bar.foo_id = foo.id where bar.in_use = 0 and bar.customer_id = 1 and foo.category = 0 That query does what I need. Now I'm trying to break the problem down in Rails using chained named_scopes. First, the straight forward in_use and customer_id scopes I have set: named_scope :available, :conditions => { :in_use => 0 } named_scope :not_available, :conditions => { :in_use => 1 } named_scope :customer, lambda { |num| { :conditions => { :customer_id => num } } } Now the part I'm stuck at, is I'm trying to do something like this in my code: abar = Bar.available.customer(1).category(0) how and where do I put the category named_scope to make this work?

• Copying files from a Rails plugin into the application upon plugin install

  - by Lou Z.

  When someone installs this plugin, I would like a file to be copied into the config/initializers directory of the app. I could do this in install.rb by copying a template file that resides somewhere in the plugin. Another option would be to require the user to run a generator after install. I know rspec-rails makes you run a generator after you install it, is that the recommended behavior? And is there anything wrong with copying files into the application in install.rb? Thanks! Lou

• Rails session cookie not getting set

  - by bwizzy

  I have a rails app that is a CMS that uses dynamic subdomains for each site. For some reason when I deployed to production the session cookie is not getting set. I'm thinking this is leading to the "Invalid Authenticity Token" errors that are being thrown everywhere. I have my production.rb setup so that I can share sessions across subdomains. What could be going wrong that the cookie isn't being set at all? #production.rb config.action_controller.session[:domain] = '.domain.com' #environment.rb config.action_controller.session = { :session_key => '_app_session', :secret => '.... nums and chars .....' }

• Limit a user to view only associated records in rails

  - by trobrock

  I have an application with three Models (Profile - SubModel - SubSubModel) chained together with has many relationships. I am trying to limit a user, after logging in, to only retrieving records that are associated with their Profile. I am very new to rails and this is what I had been trying in the Profile model has_many :submodels, :conditions => {:profile_id => self.id} but this is returning an empty data set when calling with Profile.find_by_id(1).submodels, how else could I achieve what I am trying to do. Or should I handle this in the controller or view instead, I thought it sounded well suited for the model to handle this.

• Help with a Join in Rails 3

  - by Adam Albrecht

  I have the following models: class Event < ActiveRecord::Base has_many :action_items end class ActionItem < ActiveRecord::Base belongs_to :event belongs_to :action_item_type end class ActionItemType < ActiveRecord::Base has_many :action_items end And what I want to do is, for a given event, find all the action items that have an action item type with a name of "foo" (for example). So I think the SQL would go something like this: SELECT * FROM action_items a INNER JOIN action_item_types t ON a.action_item_type_id = t.id WHERE a.event_id = 1 AND t.name = "foo" Can anybody help me translate this into a nice active record query? (Rails 3 - Arel) Thanks!

• Complex queries using Rails query language

  - by Daniel Johnson

  I have a query used for statistical purposes. It breaks down the number of users that have logged-in a given number of times. User has_many installations and installation has a login_count. select total_login as 'logins', count(*) as `users` from (select u.user_id, sum(login_count) as total_login from user u inner join installation i on u.user_id = i.user_id group by u.user_id) g group by total_login; +--------+-------+ | logins | users | +--------+-------+ | 2 | 3 | | 6 | 7 | | 10 | 2 | | 19 | 1 | +--------+-------+ Is there some elegant ActiveRecord style find to obtain this same information? Ideally as a hash collection of logins and users: { 2=>3, 6=>7, ... I know I can use sql directly but wanted to know how this could be solved in rails 3.

• Best practices for using memcached in Rails?

  - by Matt

  Hello everybody, as database transcations in our app are getting more and more time consuming, we have started to use memcached to reduce the amount of queries passed to MySQL. All in all, it works fine and really saves a lot of time. But as caching was "silently appearing" as a workaround to give the app more juice, a lot of our models now contain code like this: def self.all_cached Rails.cache.fetch('object_name') { find( :all, :include => [associations]) } end This is getting more and more a pain as filling and flushing the cache happens in several classes accross the application. Now, I was wondering if there was a better way to abstract memcached logic to make it more powerful and easy to use across all needed models? I was thinking about having some kind of memcached-module which is included in all needed modules. But before playing around, I thought: Let's ask experts first :-) Thanks Matt

  I have this method on rails so that I have an image calling a javascript function def image_to_function(name, function, html_options = {}) html_options.symbolize_keys! tag(:input, html_options.merge({ :type => "image", :src => image_path(name), :onclick => (html_options[:onclick] ?

This is how I'm using it <%= image_to_function "eliminar-icon.png", "mark_for_destroy(this, '.task')" %> Thanks alot!

• how to organize javascripts using rails and jquery

  - by VP

  Hi, i'm working in a big and rich rails web application using tons of javascript. I would like to know if anybody has a tip to organize the javascripts. Today i'm generating a new file named controller.js and adding it to my views using content_for. The problem is, some files are becoming big and sometimes, i need a function from one controller in another, so then in the end, i add a products.js to a details controller just to keep DRY. Is that solution good? Any other tip? I think the same pattern can be applied as well to css files?

• Rails NoMethodError in loop when method exists

  - by Kevin Whitaker

  Good day all. I'm running into a bit of a problem getting a script running on my production environment, even though it works just fine on my dev box. I've verified that all the requisite gems and such are the same version. I should mention that the script is intended to be run with the script/runner command. Here is a super-condensed version of what I'm trying to do, centered around the part that's broken: def currentDeal marketTime = self.convertToTimeZone(Time.new) deal = Deal.find(:first, :conditions = ["start_time ? AND market_id = ? AND published = ?", marketTime, marketTime, self.id, 1]) return deal end markets = Market.find(all) markets.each do |market| deal = market.currentDeal puts deal.subject end Now convertToTimeZone is a method attached to the model. So, this code works just fine on my dev machine, as stated. However, attempting to run it on my production machine results in: undefined method `subject' for nil:NilClass (NoMethodError) If, however, I go into the console on the production box and do this: def currentDeal marketTime = self.convertToTimeZone(Time.new) deal = Deal.find(:first, :conditions = ["start_time ? AND market_id = ? AND published = ?", marketTime, marketTime, self.id, 1]) return deal end market = Market.find(1) deal = market.currentDeal puts deal.subject It returns the correct value, no problem. So what is going on? This is on rails v 2.3.5, on both machines. Thanks for any help

• Update User Info with restful_authentication plugin in Rails?

  - by benoror

  Hi people, I want to give the users the ability to change their account info with restful_authentication plugin in rails. I added this two methods to my users controller: def edit @user = User.find(params[:id]) end def update @user = User.find(params[:id]) # Only update password when necessary params[:user].delete(:password) if pàrams[:user][:password].blank? respond_to do |format| if @user.update_attributes(params[:user]) flash[:notice] = 'User was successfully updated.' format.html { redirect_to(@user) } format.xml { head :ok } else format.html { render :action => "edit" } format.xml { render :xml => @user.errors, :status => :unprocessable_entity } end end end Also, I copied new.html.erb to edit.html.erb. Considering that resources are already defined in routes.rb I was expecting it to work easily, bute somehow when I click the save button it calls the create method, instead of update, using a POST http request. Inmediatly after that it autocatically log out form the session. Any ideas?
