• Ruby on Rails tutorial problem

  - by RailAddict

  Quick question which I hope is easily answered.. I am following this tutorial: http://oreilly.com/pub/a/ruby/archive/rails.html?page=2 and all is going well until I try create a controller and view it in my browser. The server is running and it shows the default page okay (http://127.0.0.1:3000). I ran ruby script\generate controller MyTest in my command line and it generated the correct folders and files. The problem is, when I go to http://127.0.0.1:3000/My%5FTest/ it says: We're sorry, but something went wrong. We've been notified about this issue and we'll take a look at it shortly. This must be something I have overlooked somewhere. Any help is appreciated! ruby 1.8.6 rails 2.3.4 Just checked my development logs. Here is what it says: /!\ FAILSAFE /!\ Thu Sep 24 02:21:04 +0100 2009 Status: 500 Internal Server Error no such file to load -- sqlite3 C:/Ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in

• Does acts-as-taggable-on work on heroku?

  - by Martin

  Hello, I have a question: does the acts-as-taggable-on gem work on Heroku? I'been trying but it doesn't seem to work. In my development machine works okay. I'm wondering if it's maybe because Heroku uses PostgreSQL and my local env SQLite and for some reason postgresql is not supported by the special tagging "magic"? I couldn't find any related info to this, so I would like to know other experiences with this. I guess is pretty rare since both the gem and heroku are very popular. ActionView::Template::Error (undefined method `interests' for "#<About:0x2b35d6125728>":About): <% unless @user.about.interests.empty? %> <p><strong>interests and passions</strong><br /> <% @user.about.interests.each do |tag| %> <%= tag %>, <% end -%></p><% end %> In my about.rb model i have acts_as_taggable_on :interests, :music, :movies, :books, :tvs Thank you in advance!

• How to store Ruby method references in a database?

  I am writing my first rails app. It needs to aggregate some data from multiple sites and for each site I have a unique way of getting the data (some provide RSS, some JSON, for some I scrape the HTML etc.). These will run on schedule, probably as a rake task from cron. It seems logical to store the sites and relevant information in a model, but I am not sure where to put unique data retrieval methods. Do I store method names in the model? Do I just name the methods the same as site name and call them that way? Basically, I need a way to read a list of sites and call appropriate method for each site. What is the Ruby on Rails way to do it?

• Email sent by ActionMailer is taking six hours to deliver mail.

  - by grg-n-sox

  So I have been asked to help maintain a website that uses Ruby on Rails. Now, let me just say I've been programming Ruby for awhile but I am still new to Rails. The first problem brought to my attention is how the activation email takes about six hours to arrive. It would be one thing if the email was not being sent due to errors but it is being send correctly, just slow. Also the server this is running on is also its own SMTP. I checked how the email was being formatted before calling the setup_email method and everything looks okay. I even dug into the ActionMailer lib and read through the files there and didn't see anything out of the ordinary. So what is most likely causing the email to take six hours to deliver?

• has_many :through on self?

  - by Glex

  I have a User model. A user can be either a dj, a club, or a clubber (this is controlled by the User#account_type attribute). A club can have many djs, and a dj can have many users: enumerated_attribute :account_type, %w(^clubber dj club), :nil => false do label :clubber => "Clubber" label :dj => "DJ" label :club => "Club" end has_many :dj_club_relationships, :class_name => "User", :dependent => :destroy has_many :dj_user_relationships, :dependent => :destroy has_many :djs, :through => :dj_club_relationships, :class_name => "User" has_many :users, :through => :dj_user_relationships However, this doesn't work as well as expected, since Rails doesn't know, for example, that it needs to destroy all dj_club_relationships with club_id when the user being destroyed is a club, and with dj_id when the user is a dj. How can I help rails know about it?

• Rails3 and `cd somehwere && do something`

  - by Samer Abukhait

  I have a rails project that has other projects under it, sub-projects have rake and bundler files. When I do ruby -e `cd sub-project && rake`, or ruby -e `cd sub-project && bundle`, commands work as expected and use the sub-project rake/bundler files. However, when I do the same thing from a Rails3 console (rails 3.0.3), rake gives the error no such file to load -- initializer, and bundle operates as if it was fired from the root directory. I tried the same commands from a Rails2.3.10 console and they worked as expected. Is Rails3 doing something wrong here? I am using Ruby 1.9.2 via RVM. $ ruby -v ruby 1.9.2p136 (2010-12-25 revision 30365) [i686-linux]

• undefined local variable or method 'acts_as_gmappable'

  - by MRJ

  I attempted to install the gmaps4rails gem. I added gem 'gmaps4rails' to my Gemfile, and ran 'bundle install. It said that my bundle installed successfully. I can find "Using gmaps4rails (0.8.8)" with 'gem list'. I added the specified columns to my users table with rake db:migrate and added acts_as_gmappable and the gmaps4rails_address method to my User model. Visiting pages that involve the user model gives me "undefined local variable or method 'acts_as_gmappable'"error. Is there something that I am missing? For greater context, the code I am using is from the Rails 3 Tutorial. OS X 10.6.6 ruby 1.8.7 rails 3.0.7 passenger 3.0.7

• Rake migration aborted

  - by user2537714

  I'm running Ruby 2.0.0 and I installed it correctly. Just loaded up a gem 'devise' and as I tried to migrate my database changes, it wouldn't work: $ rake db:migrate rake aborted! attr_accessible is extracted out of Rails into a gem. Please use new recommended protection model for params(strong_parameters) or add protected_attributes to your Gemfile to use old one. Then, following another Stackoverflow post, they recommended installing Bundler. I did that successfully and got this: $ bundle exec rake db:migrate rake aborted! attr_accessible is extracted out of Rails into a gem. Please use new recommended protection model for params(strong_parameters) or add protected_attributes to your Gemfile to use old one. Is anyone up to the challenge to help?

• Controller not accepting params value but the same value hard coded is accepted

• Can I use accepts_nested_attributes_for with checkboxes in a _form to select potential 'links' from a list

  - by Ryan

  In Rails 3: I have the following models: class System has_many :input_modes # name of the table with the join in it has_many :imodes, :through => :input_modes, :source => 'mode', :class_name => "Mode" has_many :output_modes has_many :omodes, :through => :output_modes, :source => 'mode', :class_name => 'Mode' end class InputMode # OutputMode is identical belongs_to :mode belongs_to :system end class Mode ... fields, i.e. name ... end That works nicely and I can assign lists of Modes to imodes and omodes as intended. What I'd like to do is use accepts_nested_attributes_for or some other such magic in the System model and build a view with a set of checkboxes. The set of valid Modes for a given System is defined elsewhere. I'm using checkboxes in the _form view to select which of the valid modes is actually set in imodes and omodes . I don't want to create new Modes from this view, just select from a list of pre-defined Modes. Below is what I'm currently using in my _form view. It generates a list of checkboxes, one for each allowed Mode for the System being edited. If the checkbox is ticked then that Mode is to be included in the imodes list. <% @allowed_modes.each do |mode| %> <li> <%= check_box_tag :imode_ids, mode.id, @system.imodes.include?(modifier), :name => 'imode_ids[]' %> <%= mode.name %> </li> <% end %> Which passes this into the controller in params: { ..., "imode_ids"=>["2", "14"], ... } In the controller#create I extract and assign the Modes that had their corresponding checkboxes ticked and add them to imodes with the following code: @system = System.new(params[:system]) # Note the the empty list that makes sure we clear the # list if none of the checkboxes are ticked if params.has_key?(:imode_ids) imodes = Mode.find(params[:imode_ids]) else imodes = [] end @system.imodes = imodes Once again that all works nicely but I'll have to copy that cludgey code into the other methods in the controller and I'd much prefer to use something more magical if possible. I feel like I've passed off the path of nice clean rails code and into the forest of "hacking around" rails; it works but I don't like it. What should I have done?

• Rails/Mongo across multiple different geo-regions

  - by wmarbut

  I have a system that by necessity requires physical presence in three or more different locations and I need advice on structuring in such a way that my database stays replicated in a timely manner without horrible latency. I've seen mysql access and replication be incredibly slow when the application server was trying to talk to a node that wasn't physically collocated. In this case I am using mongodb. The stack is linux/passenger/ruby/rails/mongodb. The database is write heavy and read light. The infrastructure is Amazon EC2 The application layer must be physically located in 3 or more different locations. I can't justify this requirement further than it is a requirement. The database, however needn't be located in more than one location if it can be written to quickly from other locations. From reading mongo's documentation, mongo replication seems like more of a candidate than sharding b/c my datastore is not huge. However I don't see anything that addresses the issue of speed for servers communicating across large distances with potentially high latency.

• My Ruby on Rails application only works if the address contains the port

  - by True Soft

  I have a Ruby on Rails application that works ok on my notebook ( http://localhost:3000/ ) I uploaded it on my hosting server, created with CPanel X an application, the URL is http://example.com:12007/ created a rewrite from http://example.com/ to http://example.com:12007/, and started it. If I write in my browser http://example.com:12007/ or http://www.example.com:12007/ all the pages work as expected. But if I write http://example.com/ or http://www.example.com/ the first page is displayed, but without any css or images (just like it wouldn't find them). I can see all the text (even the text from my MySQL database), but with no format. And if I click on any link, I get a error page like this: Not Found The requested URL /some_controller was not found on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. What should I do to make my website work without writing the port in the address bar? The content of my /public_html/.htaccess file is RewriteEngine on RewriteCond %{HTTP_HOST} ^example.com$ [OR] RewriteCond %{HTTP_HOST} ^www.example.com$ RewriteRule ^/?$ "http\:\/\/127\.0\.0\.1\:12007%{REQUEST_URI}" [P,QSA,L] which I guess was generated by CPanel Rewrites.

• Adding a transaction ID to ruby-on-rails logs

  - by Blue Warrior NFB

  We have a RoR app (rails version 3.2.15 right now). As it has been getting busier, the log-files it's producing are becoming less and less useful for troubleshooting. When they come in like this, it's not a problem: Started GET "/accounts/28088166/kittens/22894/rendered_png?file_id=5d3eaec77954a489b5ddd75143091767&kitten_store_id=9970569bbacf7b6dbeb4eb9295960d69&size=large" for 172.16.202.30 at 2013-11-12 13:45:00 +0000 Processing by KittenController#rendered_png as HTML Parameters: {"file_id"="5d3eaec77954a489b5ddd75143091767", "kitten_store_id"="9970569bbacf7b6dbeb4eb9295960d69", "size"="large", "kitten_cam_id"="280941", "id"="kjlak357aw479607t"} Rendered text template (0.0ms) Sent data (1.8ms) Completed 200 OK in 1037.4ms (Views: 1.4ms | ActiveRecord: 98.4ms) Short request, quickly assembled, all the relevant log-lines are in one block. However, not all of our code renders in 1037ms. There are a few calls that can exceed several seconds, and during that time several of these quicker ones can come in. When that happens, its very, very hard to identify which log-lines belong to which GET. Sent data (4.1ms) Completed 200 OK in 767.4ms (Views: 3.2ms | ActiveRecord: 72.2ms) Completed 200 OK in 2338.0ms (Views: 0.2ms | ActiveRecord: 0.0ms) Ooookaaaay... which goes to what? Is it possible to add something like a transaction-ID to these log-lines? The log-spam would be interspersed, but at least grep-magic would give me the unified entries that I need.

• Error trying to run rails server

  I am trying to get a basic Rails application to run on my Mac OS X 10.6.5.

• Rails & Twilio: Receiving nil when storing texts received from Twilio

  - by Jon Smooth

  I have set up the request URL in my Twilio account to have it POST to: myurl.com/receivetext. It appears to be successfully posting because when I check the database using the Heroku console I see the following: Post id: 5, body: nil, from: nil, created_at: "2012-06-14 17:28:01", updated_at: "2012-06-14 17:28:01" Why is it receiving nil for the body and from attributes? I can't figure out what I'm doing wrong! The created and updated at are storing successfully but the two attributes that I care about continue to be stored as nil. Here's the Receive Text controller which is receiving the Post request from Twilio: class ReceiveTextController < ApplicationController def index @post=Post.create!(body: params[:Body], from: params[:From]) end end EDIT: When I dump the params I receive the following: "{\"controller\"=\"receive_text\", \"action\"=\"index\"}" I attained this by inserting the following into my ReceiveText controller. @params = Post.create!(body: params.inspect, from: "Dumping Params") and then opening up the Heroku console to find the database entry with from = "Dumping Params". I simulated a Twilio request with a curl with the following command curl -X POST myurl.com/receivetext route -d 'AccountSid=AC123&From=%2B19252411234' I checked the production database again and noticed that the curl request did work when obtaining the FROM atribute. It stored the following: params.inspect returned "{\"AccountSid\"=\"AC123\", \"From\"=\"+19252411234\", \"co..." I received a comment stating: "As long as twilio is hitting the same URL with the same method (GET/POST) it should be filling the params array as well" I have no idea how to make this comment actionable. Any help would be greatly appreciated! I'm very new to rails. Here's my database migration (I have both attributes set to string. I have tried setting it to text and that didn't work either) : class CreatePosts < ActiveRecord::Migration def change create_table :posts do |t| t.string :body t.string :from t.timestamps end end end Here is my Post model: class Post < ActiveRecord::Base attr_accessible :body, :from end Routes (everything appears to be routing just fine) : MovieApp::Application.routes.draw do get "receive_text/index" get "pages/home" get "send_text/send_text_message" root to: 'pages#home' match '/receivetext', to: 'receive_text#index' match '/pages/home', to: 'pages#home' match '/sendtext', to: 'send_text#send_text_message' end Here's my gemfile (incase it helps) source 'https://rubygems.org' gem 'rails', '3.2.3' gem 'badfruit' gem 'twilio-ruby' gem 'logger' gem 'jquery-rails' group :production do gem 'pg' end group :development, :test do gem 'sqlite3' end group :assets do gem 'sass-rails', '~> 3.2.3' gem 'coffee-rails', '~> 3.2.1' gem 'uglifier', '>= 1.0.3' end

• What to Expect in Rails 4

  - by mikhailov

  Rails 4 is nearly there, we should be ready before it released. Most developers are trying hard to keep their application on the edge. Must see resources: 1) @sikachu talk: What to Expect in Rails 4.0 - YouTube 2) Rails Guides release notes: http://edgeguides.rubyonrails.org/4_0_release_notes.html There is a mix of all major changes down here: ActionMailer changes excerpt: Asynchronously send messages via the Rails Raise an ActionView::MissingTemplate exception when no implicit template could be found ActionPack changes excerpt Added controller-level etag additions that will be part of the action etag computation Add automatic template digests to all CacheHelper#cache calls (originally spiked in the cache_digests plugin) Add Routing Concerns to declare common routes that can be reused inside others resources and routes Added ActionController::Live. Mix it in to your controller and you can stream data to the client live truncate now always returns an escaped HTML-safe string. The option :escape can be used as false to not escape the result Added ActionDispatch::SSL middleware that when included force all the requests to be under HTTPS protocol ActiveModel changes excerpt AM::Validation#validates ability to pass custom exception to :strict option Changed `AM::Serializers::JSON.include_root_in_json' default value to false. Now, AM Serializers and AR objects have the same default behaviour Added ActiveModel::Model, a mixin to make Ruby objects work with AP out of box Trim down Active Model API by removing valid? and errors.full_messages ActiveRecord changes excerpt Use native mysqldump command instead of structure_dump method when dumping the database structure to a sql file. Attribute predicate methods, such as article.title?, will now raise ActiveModel::MissingAttributeError if the attribute being queried for truthiness was not read from the database, instead of just returning false ActiveRecord::SessionStore has been extracted from Active Record as activerecord-session_store gem. Please read the README.md file on the gem for the usage Fix reset_counters when there are multiple belongs_to association with the same foreign key and one of them have a counter cache Raise ArgumentError if list of attributes to change is empty in update_all Add Relation#load. This method explicitly loads the records and then returns self Deprecated most of the 'dynamic finder' methods. All dynamic methods except for find_by_... and find_by_...! are deprecated Added ability to ActiveRecord::Relation#from to accept other ActiveRecord::Relation objects Remove IdentityMap ActiveSupport changes excerpt ERB::Util.html_escape now escapes single quotes ActiveSupport::Callbacks: deprecate monkey patch of object callbacks Replace deprecated memcache-client gem with dalli in ActiveSupport::Cache::MemCacheStore Object#try will now return nil instead of raise a NoMethodError if the receiving object does not implement the method, but you can still get the old behavior by using the new Object#try! Object#try can't call private methods Add ActiveSupport::Deprecations.behavior = :silence to completely ignore Rails runtime deprecations What are the most important changes for you?

  I have set up Rails, Passenger, nginx, and PostgreSQL on Ubuntu Server 12.04LTS. Upon trying to access the application/website, however, I am greeted with an error page saying that the application could not be started because a source file is missing. Error message: cannot load such file -- bundler. My nginx config (/opt/nginx/conf/nginx.conf): user railsapp; worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; passenger_root /home/railsapp/.rvm/gems/ruby-1.9.3-p194/gems/passenger-3.0.14; passenger_ruby /home/railsapp/.rvm/rubies/ruby-1.9.3-p194/bin/ruby; server { listen 80; server_name fitness_schedules.local; root /home/railsapp/fitness_schedules/public; passenger_enabled on; rack_env development; } } Here is the error message: A source file that the application requires, is missing. It is possible that you didn't upload your application files correctly. Please check whether all your application files are uploaded. A required library may not installed. Please install all libraries that this application requires. Further information about the error may have been written to the application's log file. Please check it in order to analyse the problem.

• PG::Error: ERROR: operator does not exist: integer ~~ unknown

  - by rsvmrk

  I'm making a search-function in a Rails project with Postgres as db. Here's my code def self.search(search) if search find(:all, :conditions => ["LOWER(name) LIKE LOWER(?) OR LOWER(city) LIKE LOWER(?) OR LOWER(address) LIKE LOWER(?) OR (venue_type) LIKE (?)", "%#{search}%", "%#{search}%", "%#{search}%", "%#{search}%"]) else find(:all) end end But my problem is that "venue_type" is an integer. I've made a case switch for venue_type def venue_type_check case self.venue_type when 1 "Pub" when 2 "Nattklubb" end end Now to my question: How can I find something in my query when venue_type is an int?

• MySQL to PostreSQL and Named Scope

  - by Lowgain

  I've got a named scope for one of my models that works fine. The code is: named_scope :inbox_threads, lambda { |user| { :include => [:deletion_flags, :recipiences], :conditions => ["recipiences.user_id = ? AND deletion_flags.user_id IS NULL", user.id], :group => "msg_threads.id" }} This works fine on my local copy of the app with a MySQL database, but when I push my app to Heroku (which only uses PostgreSQL), I get the following error: ActiveRecord::StatementInvalid (PGError: ERROR: column "msg_threads.subject" must appear in the GROUP BY clause or be used in an aggregate function: SELECT "msg_threads"."id" AS t0_r0, "msg_threads"."subject" AS t0_r1, "msg_threads"."originator_id" AS t0_r2, "msg_thr eads"."created_at" AS t0_r3, "msg_threads"."updated_at" AS t0_r4, "msg_threads"."url_key" AS t0_r5, "deletion_flags"."id" AS t1_r0, "deletion_flags"."user_id" AS t1_r1, "deletion_flags"."msg_thread_id" AS t1_r2, "deletion_flags"."confirmed" AS t1_r3, "deletion_flags"."created_at" AS t1_r4, "deletion_flags"."updated_at" AS t1_r5, "recipiences"."id" AS t2_r0, "recipiences"."user_id" AS t2_r1, "recipiences"."msg_thread_id" AS t2_r2, "recipiences"."created_at" AS t2_r3, "recipien ces"."updated_at" AS t2_r4 FROM "msg_threads" LEFT OUTER JOIN "deletion_flags" ON deletion_flags.msg_thread_id = msg_threads.id LEFT OUTER JOIN "recipiences" ON recipiences.msg_thread_id = msg_threads.id WHERE (recipiences.user_id = 1 AND deletion_flags.user_id IS NULL) GROUP BY msg_threads.id) I'm not as familiar with the working of Postgres, so what would I need to add here to get this working? Thanks!
