问题 My current Sidekiq setup with the following is processing the image, but nothing is being done in the background. The page takes 10 seconds to load and then the new image is shown on the redirected page with the following path. https://d9vwx0ll7rhpx.cloudfront.net/development/photo/image/product_thumb/product_thumb_0046d4ca-ca8d-4c02-b8cd-da0255c5736e.jpg I would like for this process to be done in the background. def create @photo = Photo.new(photo_params) if @photo.save UploadsWorker

问题 I am getting this error whenever I load Guard and I think it fails to precompile locally my assets due to this. When I load guard with $ guard I get: 16:55:35 - ERROR - Guard::RailsAssets failed to achieve its <start>, exception was: > [#6D5274147654] TypeError: can't modify immutable index > [#6D5274147654] /home/mathieu/.rvm/gems/ruby-2.0.0-p451@rails3tutorial2ndEd/gems/sprockets-2.12.3/lib/sprockets/index.rb:81:in `expire_index!' > [#6D5274147654] /home/mathieu/.rvm/gems/ruby-2.0.0-p451

问题 I did some restructuring of our less files. Everything works locally (e.g. rake assets:precompile ), but on Heroku my push fails with the following: Running: rake assets:precompile adding placeholder rake aborted!

问题 Spent all day trying to fix this.. Basically the controller is calling worker to perform the creation of "Balance". The worker performs with success and the record is created but when it returns to the controller it can't find the object created. How to force it looking for the "updated database" records ? Controller: balance = BalanceCreator.perform_async(userx.id, market.id) 20.times do status = Sidekiq::Status::get balance, :exp_status if ["done"].include?(status) break end sleep(0.2) end

问题 I have a rails app where many of the models are editable using best_in_place, so I have a lot of controllers that look partially like this: before_action :find_objects, except: [:new, :create] def update @object.update_attributes(object_params) respond_to do |format| format.json { respond_with_bip @object} end end private def object_params params.require(:object).permit(:foo, :bar) end def find_objects @object = Object.find(params[:id]) end How do I move this particular repeated piece into a

问题 I'm writing a simple chat, and I need to list out users online. I don't use devise for authentication, there's a custom user model which authenticates via omniauth . user.rb class User < ActiveRecord::Base has_many :messages, dependent: :delete_all class << self def from_omniauth(auth) provider = auth.provider uid = auth.uid info = auth.info.symbolize_keys! user = User.find_or_initialize_by(uid: uid, provider: provider) user.name = info.name user.avatar_url = info.image user.profile_url =

问题 I am using Devise to authenticate and register users in my Rails app. However, I only want users who have an email with a specific ending to be able to sign up and access it (let's say @xyz.com).
