问题 I have a nginx + thin + Rails 3.2 setup. Currently I am trying to setup nginx so it can serve cached pages directly. However nginx still pass *.html request to Rails in the following nginx configuration files. The html files exists in public folder, and nginx does find them, just that they are still passed to Rails. upstream site { server unix:/home/site/deploy/site/shared/pids/thin.0.sock; } server { listen 80; server_name www.example.com; rewrite ^(/.*) http://example.com$1 permanent; } #

问题 So, I'd like to drop the current primary key on my users table.. I think it's on the email column. And add a primary key to the uid column instead to get my omniauth working. schema.rb snippit create_table "users", force: true do |t| t.string "email", default: "", null: false t.string "encrypted_password", default: "", null: false t.string "reset_password_token" t.datetime "reset_password_sent_at" t.datetime "remember_created_at" t.integer "sign_in_count", default: 0 t.datetime "current_sign

问题 I've been using RubyMine and like it a lot so far. Is there any way to only step through my project files? When I click "Step Over" or "Step Out" I'm taken into framework and library files, which I don't need to look at. 回答1: RubyMine doesn't currently have this feature; here is the relevant enhancement request. 来源： https://stackoverflow.com/questions/7732660/debugging-rubymine-only-debug-project-files

问题 I'm trying to run rails server and I'm seeing something like this: C:\Users\Mama i Tata>cd c:/rails_project/my_app c:\rails_project\my_app>rails s => Booting WEBrick => Rails 3.2.6 application starting in development on http://0.0.0.0:3000 => Call with -d to detach => Ctrl-C to shutdown server Exiting c:/rails_project/my_app/config/routes.rb:1:in `<top (required)>': uninitialized constant SampleApp (NameError) from C:/Ruby193/lib/ruby/gems/1.9.1/gems/railties-3.2.6/lib/rails/applic ation

问题 I have a model with a Time attribute. I want to check that time can not be empty (better choice probably would be to check that input is time but i have no ideas how to deal with that). I tried this validation: # id :integer not null, primary key # school_class_id :integer # meeting_time :time class Meeting < ActiveRecord::Base validates :meeting_time, :presence => { :message => "can't be empty!" } end Then i tried to check this in spec and this fails (empty time is ok but it should not be).

问题 Not sure what I'm doing wrong on this one. I've followed the Rails Cast for Carrierwave but am having a strange bug where the image isn't showing at all - the (HTML) source code is showing the image tag but nothing inside it. Portfolio Model code: class Portfolio < ActiveRecord::Base validates :title, :content, presence: true mount_uploader :feature_image, FeatureImageUploader end Feature Image Uploader code: class FeatureImageUploader < CarrierWave::Uploader::Base storage :file def store_dir

问题 I am writing request specs and I am using poltergeist-1.0.2 and capybara-1.1.2. I have the following code: login_as @user, 'Test1234!' click_on 'Virtual Terminal' the login has flash message that shows to the user that he is successfully logged in. When I am using click_link, the spec fails because Capybara can't find element 'Virtual Terminal' but when I am using click_on everything passes. 'Virtual Terminal' is not a button, it is a link. What is the difference between click_on and click

问题 I am using multiple redirects, and I would like to redirect from A->B->C->A. So in B, I save path A as @previouspage = request.referer and so @previouspage = A at this point, but when I call @previouspage in C, it doesn't bring the hard value saved in B, but finds its own relative request.referer, which is B. So in C, @previouspage = B (because I think variables in Ruby are soft-links) How would I just save whatever the value of request.referer was at point B, and then save that URL into a
