问题 I am trying to move my project to production, trying to RAILS_ENV=production bundle exec rake assets:precompile gives me an error, without specifying in which file it is. rake aborted! Sass::SyntaxError: Invalid CSS after "}": expected selector or at-rule, was "}" (sass):89 /Users/mac/.rvm/gems/ruby-2.2.3/gems/sass-3.4.23/lib/sass/scss/parser.rb:1207:in `expected' /Users/mac/.rvm/gems/ruby-2.2.3/gems/sass-3.4.23/lib/sass/scss/parser.rb:1137:in `expected' /Users/mac/.rvm/gems/ruby-2.2.3/gems

问题 My production environment is : ruby 1.9.2-p320 , rails 3.2.7, paperclip 3.1.4, mysql, Ubuntu 8.10 x86 64bit. I have a Errno:EACCES Permission denied /system error when i try to upload a file with paperclip. Useless to say that locally this doesn't happen. I checked the public directory permissions and it's 775, the public/system permission is 777 as well as all it's inner directory. The tmp directory permission is : 775 too. Moreover the user used to deploy the application is www-data:root

问题 I just got done setting up my rails environment on my old mac book and ran into this error. I've installed FFI and rb-inotify. I've also ran bundle install again. I've looked at https://github.com/ffi/ffi/issues/66 and https://groups.google.com/forum/?fromgroups=#!topic/ruby-ffi/gj3_k34o80k which both indicate that this is a linux specific API. There is a suggestion on the second of those links that says I should just remove that gem and things that depend on it, but I am hesitant to remove

问题 Background I have an app that I recently updated to Rails 3.2.1 (from Rails 3.0.x) and have refactored the JS and CSS assets to make use of the new asset pipeline. The app is hosted on Heroku with the Celadon Cedar stack. App Config I keep application specific configuration in a YAML file called app_config.yml and load it into a global APP_CONFIG variable using an initializer: # config/initializers/load_app_config.rb app_config_contents = YAML.load_file("#{Rails.root.to_s}/config/app_config

问题 We have a rails application and we have a API namespace defined as Api::V1, Api::V1_2, Api::V1_3 etc. In routes.rb, we have set the following namespace :api do ["v1", "v1.2", "v1.3", "latest"].each do |name| namespace name, {:module => name.gsub(".","__"), :as => name.gsub(".","_") } do constraints :format => /json/ do # user scoped views resources :some_endpoint, :only => [:create, :index, :show, :update, :delete], :path => "scheduler" do member do put 'edit' post 'duplicate' end end end end

问题 I have three tables, accounts, campaigns and accounts_campaigns. I want to have checkboxes for select accounts in the campaigns edit form. I have Campaign's model like this: class Campaign < ActiveRecord::Base has_and_belongs_to_many :accounts accepts_nested_attributes_for :accounts end I think i dont need to define the relationship on Account. And my form is: = hidden_field_tag "campaign[accounts_ids][]", nil - Account.all.each do |account| %label.checkbox = check_box_tag "campaign[accounts

问题 I've noticed that when logging to Devise I have started to receive these error message. I'm using Devise 2.2.4 with Omniauth 1.1.4 and Omniauth-Facebook 1.4.1 Does anybody know what is the cause of this error? ActionView::Template::Error (undefined method `omniauth_authorize_path' for #<#<Class:0xb85e534>:0xb904e5c>): 21: <%- if devise_mapping.omniauthable? %> 22: <%- resource_class.omniauth_providers.each do |provider| %> 23: <% logger.info "hey #{provider} , dolphin and #{resource_name}" %>

问题 Just out of curiosity, is there a way to say this... user.update_column(:field1, true) user.update_column(:field2, true) ... in one line in Ruby on Rails? As far as I know an update_columns method does not exist... 回答1: You can use update_all as follows: User.where(:id => user.id).update_all({:field1 => true, :field2 => true}) This will generate the following update statement (mysql): UPDATE users SET field1 = 1, field2 = 1 WHERE users.id = <whatever> Callbacks and validations will not be run
