  • 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?

  • What is a valid and reasonable alternative to a massive storage approach?

    - by Backo
    I am using Ruby on Rails 3.2.2 and MySQL. After my previous question on "how to handle massive storage of records in database for user authorization purposes", since related answers (on how to solve the issue or how to accomplish to that I am looking for) aren't sufficiently detailed or require to much resources (at least for me), I would like to know what are valid and reasonable alternatives to that approach. In few words, this question could be phrase as: how to handle "complex" (at level of SQL querying) user authorizations when you have to fetch "authorized" records? That is, for example, how to retrieve records when you would use code like the following (the following code would be used mostly in index controller actions): Article.readable_by_user(@current_user) # => Returns all articles readable by the current user.

  • Compiling Ruby on Mac OS X Snow Leopard

    - by gryzzly
    Hi, I am trying to follow this tutorial, on the subject of compiling ruby and rubygems on Snow Leopard: http://hivelogic.com/articles/compiling-ruby-rubygems-and-rails-on-snow-leopard I have added this to my ~/.profile: export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH" But if I write: echo $PATH I get: /opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:/usr/X11/bin But in tutorial it says: You should see /usr/local/bin at the beginning of the line returned by the system. I have installed macports sometime ago and plenty of other software, perhaps it has changed the path. Anyway, I have tried to proceed with the installation, so I have built ruby, I did: ./configure --enable-shared --enable-pthread CFLAGS=-D_XOPEN_SOURCE=1 make sudo make install cd .. But when I do which ruby I get: /usr/bin/ruby And according to the tutorial that's wrong. Also if I do ruby -v I get the older version of ruby that was preinstalled on Snow Leopard and not the one I've compiled. Thanks.

  • Ruby on Rails has_one Model Not Supplying ID Column

    - by Metric Scantlings
    I have a legacy rails (version 1.2.3) app which runs without issue on a number of servers (not to mention my local environment). Deployed to its newest server, though, and I now get ActiveRecord::StatementInvalid: Mysql::Error: #23000Column 'video_id' cannot be null errors. Below are the models/relationships, simplified: class Video < ActiveRecord::Base has_one(:user, :dependent => :destroy) end class User < ActiveRecord::Base belongs_to(:video) end And below is a rails console transcript of the relationships failing: >> video = Video.create(:title => 'New Video') => #<Video:0xb6d5e31c>... >> video.id => 5 >> video.user = User.create(:name => 'Tester') ActiveRecord::StatementInvalid: Mysql::Error: #23000Column 'video_id' cannot be null: INSERT INTO users (`name`, `video_id`) VALUES('Tester', NULL) from /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/active_record/connection_adapters/abstract_adapter.rb:128:in `log' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/active_record/connection_adapters/mysql_adapter.rb:243:in `execute' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/active_record/connection_adapters/mysql_adapter.rb:253:in `insert' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/active_record/base.rb:1811:in `create_without_callbacks' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/active_record/callbacks.rb:254:in `create_without_timestamps' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/active_record/timestamp.rb:39:in `create' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/active_record/base.rb:1789:in `create_or_update_without_callbacks' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/active_record/callbacks.rb:242:in `create_or_update' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/active_record/base.rb:1545:in `save_without_validation' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/active_record/validations.rb:752:in `save_without_transactions' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/active_record/transactions.rb:129:in `save' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/active_record/connection_adapters/abstract/database_statements.rb:59:in `transaction' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/active_record/transactions.rb:95:in `transaction' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/active_record/transactions.rb:121:in `transaction' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/active_record/transactions.rb:129:in `save' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/active_record/base.rb:451:in `create' from (irb):3 from :0 Has anyone else come across ActiveRecord not sending an ID when it clearly knows it?

  • Is it possible for beginner to learn and develop an application in rails in 4 months?

    - by Parth
    I want to develop a web application or a website using rails. My current knowledge includes 1. HTML 2. CSS 3. C 4. Java And I am currently going through 5th chapter of the well grounded rubyist book by David A. Thomas. I came to know that learning ruby is beneficial for good knowledge of rails. So currently I am going through the basics of ruby. And learning rails in parallel. I want to know if in this scenario is it practically feasible to understand rails and develop an application/website in it within the time frame of 4 months. I need to develop an application which have atleast 3 complexity (complex functionality). Any ideas of good application for rails beginners is welcomed. But the application should be large or if it is small than it should have some complexity. Time is a constraint for me. I would have to develop application for college work but rails technology is my choice as I want to learn it.

  • Installing and using acts-as-taggable-on

    - by seaneshbaugh
    This is going to be a really dumb question, I just know it, but I'm going to ask anyways because it's driving me crazy. How do I get acts-as-taggable-on to work? I installed it as a gem with gem install acts-as-taggable-on because I can't ever seem to get installing plugins to work, but that's a whole other batch of questions that are all probably really dumb. Anyways, no problems there, it installed correctly. I did ruby script/generate acts_as_taggable_on_migration and rake db:migrate, again no problems. I added acts_as_taggable to the model I want to use tags with, started up the server and then loaded the index for the model just to see if what I've got so far is working and got the following error: undefined local variable or method `acts_as_taggable' for #. I figure that just means I need to do something like require 'acts-as-taggable-on' to my model's file because that's typically what's necessary for gems. So I did that hit refresh and got uninitialized constant ActiveRecord::VERSION. I'm not even going to pretend to begin to know what that means went wrong. Did I go wrong somewhere or there something else I need to do. The installation instructions seem to me like they just assume you generally know what you're doing and don't even begin to explain what to do when things go wrong.

    I am new to Ruby on Rails. I have a migration called create user class CreateUsers < ActiveRecord::Migration def change create_table :users do |t| t.column :username, :string, :limit => 25, :default => "", :null => false t.column :hashed_password, :string, :limit => 40, :default => "", :null => false t.column :first_name, :string, :limit => 25, :default => "", :null => false t.column :last_name, :string, :limit => 40, :default => "", :null => false t.column :email, :string, :limit => 50, :default => "", :null => false t.column :display_name, :string, :limit => 25, :default => "", :null => false t.column :user_level, :integer, :limit => 3, :default => 0, :null => false end User.create(:username=>'test',:hashed_password=>'test',:first_name=>'test',:last_name=>'test',:email=>'[email protected]',:display_name=> 'test',:user_level=>9) end end When I run rake db:migrate the table is created with the columns as mentioned above but the test data are not there mysql>select * from users; Empty set (0.00 sec) EDIT I just dropped the whole database and restarted the migration and now it is showing the following error. rake aborted! An error has occurred, all later migrations canceled: Can't mass-assign protected attributes: username, hashed_password, first_name, last_name, email, display_name, user_level What am I doing wrong please help? Thank you.

  • Rails3 environment running very slow on Windows XP, Ubuntu 9.04, Ubuntu 9.10

    - by bergyman
    I've tried all three (granted the Ubuntu versions were via VirtualBox with XP as a host, but I gave the images all the available RAM my system has). Loading the rails environment is taking 30-60 seconds. rails console, rake test:units - anything that requires rails to load up. And not just on the first go - every time. I've even used autotest to see if it helps with execution time for unit tests, but it doesn't. Any time I change one test, it still takes 30 seconds to load them, and then about 4 seconds to execute. Has anyone else come across this issue? Has anyone figured out any way to fix this?

  • [BUG] gc_sweep() with ruby 1.8.7

    - by kgrad
    I have a rails app being developed with mongrel 1.1.5. I can run the app and click on 3 or 4 links, but after that mongrel always crashes with an error: [BUG] gc_sweep(): unknown data type 0x0. It happens on both windows 7 and mac os x snow leopard, so it has to be something in my code, or something wrong with ruby 1.8.7 (less likely). Has anyone else experienced this? Is there a fix or likely cause? thanks edit: interestingly, it does not crash when deployed via heroku.

  • Ruby/Rails display general screen when modifications being performed on server

    - by john chan
    I have a ruby on rails app running a server and sometimes it needs to be taken down for updates/etc. As of now, one way I see to have a general display screen during update periods (when the app is down) is to substitute the files within /srv/www/ directory to just have it display a general screen everywhere that the user could possibly navigate to. I also thought of having a central controller file that connects all others (essentially a main) but this seems counter intuitive for rails. There are many external links to these different components of the site that the user could navigate to from outside and I need to make sure that they always receive this general update screen when the app is taken down for a little. I was wondering if anyone had any other ideas.... maybe a library or something like that, I can't seem to find anything online. any suggestions would be appreciated. Thanks

  • PostgreSQL / Ruby for commercial application

    - by RPK
    I am planning a web-based commercial application with front-end RoR and back-end PostgreSQL. I've some confusion about RoR and PostgreSQL Edition to use. For RoR, I have Aptana RADRails installed. For PostgreSQL, a free variant is also available at EnterpriseDB. Previously I installed a free EnterpriseDB PostgreSQL variant and it was very smooth and had professional touch. It was quite different from the one available from PostgreSQL website. I want to know which IDE and RoR variant to use for my project. I have no idea of Ruby and Rails. I will be learning and developing simultaneously. Also, which PostgreSQL variant to use? Can these two technologies be used for a developing a commercial application?

  • Automated testing with Ruby on Rails - best practices

    - by randombits
    Curious, what are you folks doing in as far as automating your unit tests with ruby on rails? Do you create a script that run a rake job in cron and have it mail you results? a pre-commit hook in git? just manual invokation? I understand tests completely, but wondering what are best practices to catch errors before they happen. Let's take for granted that the tests themselves are flawless and work as they should. What's the next step to make sure they reach you with the potentially detrimental results at the right time?

  • Displaying most popular posts on my blog - Ruby on Rails

    - by bgadoci
    I have created a simple blog application using Ruby on Rails, both of which I am new to. I am trying to get my most 'voted' posts to display in my /views/posts/index.html.erb view. Here are the basics. I have created a votes table and successfully allow a user to 'vote' for a post on the /views/posts/show.html.erb page. When they vote, it passes '1' to the votes table and I return the vote count via ajax to the same show page. Vote belongs_to :post and Post has_many :votes. I would like to display in /views/posts/index.html.erb the post title and the amount of times it has been voted for, ordered by posts with the highest vote count. Any ideas on how to do this?

  • Ruby CMS/blog: Mephisto vs. Radiant

    - by Candidasa
    I'm looking for a blogging tool with some light CMS features in Ruby on Rails. I mainly want something simple, but configurable. I have no need for page snippets, etc. Just your basic main blog, very good (and easy) theme support, some nice sidebar stuff, a few static pages and MetaWeblog API support. I'm thinking of either using Mephisto or Radiant CMS (everything else seems half-baked or extremely lightweight at best): http://mephistoblog.com/ http://www.radiantcms.org/ Documentation for Mephisto seems very lacking and their site is a mess. I've also read some bad things about it's stability. Radiant seems more stable in comparison and has heaps of useful plug-ins. However, it isn't designed for blogging out of the box. That has to be added as almost an after thought. Creating a custom theme also seems more cumbersome with Radiant due to the sub-page/snippet feature. Which should I choose?

  • getting rid of ruby gems that won't die

    - by holden
    I've got a few ruby gems that won't go away. I think it has to do with when I installed them. Occasionally I have forgotten to use "sudo" before doing a gem install, which results in a write error and from what I can gather puts a copy of the gem in my user directory instead of somewhere it can run. But gem uninstall doesn't work. It continually shows up in 'gem list' but can't uninstall it from either gem uninstall, or sudo gem uninstall. I tried directly deleting one gem after finding the path in my 'gem environment', but that still left the gem on the list. Also is it possible just to remove all gems and start from scratch? These are driving me nuts. I'm running OS X. Thanks,

  • ruby syntactic sugar: dealing with nils..

    - by luca
    probably asked already but I couldn't find it.. here are 2 common situation (for me while programming rails..) that are frustrating to write in ruby: "a string".match(/abc(.+)abc/)[1] in this case I get an error because the string doesn't match, therefore the [] operator is called upon nil. What I'd like to find is a nicer alternative to the following: temp="a string".match(/abc(.+)abc/); temp.nil? ? nil : temp[1] in brief, if it didn't match simply return nil without the error The second situation is this one: var = something.very.long.and.tedious.to.write var = something.other if var.nil? In this case I want to assign something to var only if it's not nil, in case it's nil I'll assign something.other.. Any suggestion? Thanks!

  • Action Mailer Confirmation Emails - Ruby on Rails...

    - by bgadoci
    I have successfully installed the Clearance Gem from ThoughtBot. Clearance sends a confirmation email upon a new sign_up and suggests adding: config.action_mailer.default_url_options = { :host => 'localhost:3000' } to your /environments/test.rb and development.rb. I have tried this and also config.action_mailer.default_url_options = { :host => '127.0.0.1', :port => 3000 } But can't seem to get rails to send the email. As I am new to both Ruby and Rails, I am wondering if there is some step/config that ThoughtBot is assuming I have already done to send emails. What am I doing wrong/missing? UPDATE: Just added notifier.rb class Notifier < ActionMailer::Base recipients recipient.email_address_with_name bcc ["[email protected]"] from "[email protected]" subject "New account information" body :account => recipient end end

  • validating creation by post_id and ip_address - Ruby on Rails

    - by bgadoci
    I have created a blog application using Ruby on Rails which includes the ability to vote on posts. A user can click vote and a record is created in the vote table. I am now trying to limit that same person from voting for a post multiple times. class Post has_many :votes end class Vote belongs_to :post end When a vote record is created I am using the VotesController to pass the :post_id and using a hidden field in the view to pass the ip_address (both to the vote table). I am wondering if there is a way to add a validation to the Vote Model that searches to see if a post_id has an ip_address that matches the person requesting to vote. I have tried simply using the validates_uniqueness_of :ip_address but that restricts the user from voting on any post. I just want to restrict the user from voting on a particular post that they have already voted on. Is there a way to do this through validation?

  • Learning Ruby on Rails

    - by Ethan Gunderson
    As it stands now I'm a Java and C# developer, but the more and more I look at Ruby on Rails, the more I really want to learn it. What have you found to be the best route to learn RoR? Would it be easier to develop on Windows, or should I just run a virtual machine with linux? Is there an ide that can match the robustness of Visual Studio? Any programs to develop that give a good overhead of what to do? Any good books? Seriously, any tips/tricks/rants would be awesome.
