问题 I have two rails apps. The first app constantly calculates some data and stores it in Redis (This app is running on JRuby 1.7.4 and Rails 4). The second app reads this data from the same Redis server (This app is running on Ruby 2.0.0 and Rails 4). After trying to achieve this configuration in my local development environment, it's apparent that my Redis data is not being shared between the two apps. In both apps, my config/initializers/redis.rb file looks like this: uri = URI.parse(ENV[

问题 I could not find a "direct" answer to this anywhere. Since I know there will be many other "Late Upgraders" to the party, I feel I need to get this out. I had a Rails 4.0.0 app running Ruby 2.0.0-p247. After upgrading to 4.0.13, I ran into this error: private method `include' called for ActionDispatch::Assertions:Module (NoMethodError) I received this through rspec and WEBrick. 回答1: I found a solution via another issue from layer-ruby: NoMethodError: private method `include' called for #

问题 I need to monkey-patch one of the Rails core classes, specifically ActionView::Helpers::UrlHelper::ClassMethods.link_to method. As far as I remember there are some events fired when parts of Rails are loaded, how to add handlers for them? Or should I just put the code into initializer? 回答1: link_to does not appear to be in ClassMethods. From here. In config/initializers/url_helper_extensions.rb module ActionView module Helpers module UrlHelper alias_method :_link_to, :link_to def link_to #

问题 I am working on a rails app that has a WP home page, and also some images that are being load from WP. On localhost we don't have access to WP content that leads to having a lot of routing errors in logs, in example: Started GET "/wp-content/uploads/2014/03/facebook-icon1.png" for 127.0.0.1 at 2015-11-20 15:10:48 +0200 ActionController::RoutingError (No route matches [GET] "/wp-content/uploads/2014/03/facebook-icon1.png"): actionpack (4.2.5) lib/action_dispatch/middleware/debug_exceptions.rb

问题 I added the key into heroku config var, but I'm still getting the error. Is this the correct way? I ignored secrets.yml as I read from other sources that its not a good idea to push this to the public. in the heroku config var: [key] SECRET_KEY_BASE [value] 3280570382948240938 in secrets.yml production: secret_key_base: <%= ENV["SECRET_KEY_BASE"] %> What am I still doing wrong? Furthermore, if I put my secret keys into heroku's config variable, don't other developers get to see this too? So,
