Start or ensure that Delayed Job runs when an application/server restarts

阅读更多关于 Start or ensure that Delayed Job runs when an application/server restarts

问题 We have to use delayed_job (or some other background-job processor) to run jobs in the background, but we're not allowed to change the boot scripts/boot-levels on the server. This means that the daemon is not guaranteed to remain available if the provider restarts the server (since the daemon would have been started by a capistrano recipe that is only run once per deployment). Currently, the best way I can think of to ensure the delayed_job daemon is always running, is to add an initializer

问题 what plugin or gem do you recommened for tagging? There are many of them, acts_as_taggable, acts_as_taggable_on_steroids, acts_as_taggable_on,...

Started with is_taggable because I liked having something simple Then I need to find tagged items like Website.tagged_with("sports") which it didn't support so I switched to acts_as_taggable_on , the most popular one on github It worked well

Building a ruby gem for Rails applications

阅读更多关于 Building a ruby gem for Rails applications

问题 As a Rails developer I feel a bit stupid asking this question but hopefully I will learn something new and someone can put me out of my misery! In my rails applications I use (other peoples) gems all the time, I also use plugins from the community or my own. I understand the benefits of use gems over plugins as they are version-able, segmented, system wide, easier to manage and share etc etc but I don't really know how to go about making a gem for my rails apps!? Do you always start with a

“Like”, “Dislike” plugin for rails

阅读更多关于 “Like”, “Dislike” plugin for rails

Is there any "like" , "dislike" plugin for rails... I went through rating plugins... but all of them were 5 star rating plugins... I recommend creating the like and dislike option by taking on the classic vote model functionality. So you have Vote as a join table between the User and the Votable Item . A Vote value can work as Vote.value + 1 = Like, Vote.value -1 = Dislike, Vote.value = Neutral/Didn't vote. Your controller for your votable item can look like this : def like get_vote @vote.value += 1 unless @vote.value == 1 @vote.save respond_to do |format| format.html format.js end end def

OmniAuth + Pulling Tweets, FB Places, etc

阅读更多关于 OmniAuth + Pulling Tweets, FB Places, etc

I'm using OmniAuth + Devise to allow users to register using Facebook/Twitter/Gowalla/etc attached to normal user accounts. Now when a user logs in using any of these, or their account, all their social networks are attached in a authentications table. I need to be able to pull content from any of these providers, such as their tweets or their Facebook Places checkings, etc. I understand that I will need to use a different gem, plugin, whatever to do this but getting the config I need to work with those gems (and make requests) is confusing to me. I need to be able to access the provider

How to load vendor asset folder in Rails 4?

阅读更多关于 How to load vendor asset folder in Rails 4?

I have a plugin with many types of files, and its own tree structure (html, css, js, documentation, images, etc) Rather than going through the plugin folder, and splitting all the css and js files into the vendor/assets/js/ vendor/assets/css/ folders, I want to just keep the entire plugin folder as is. For example, vendor/assets/multipurpose_bookshelf_slider/ How do I make sure the paths load properly, and reference them in my manifest files? Currently, I have some files place as follows (not exhaustive) /my_app/vendor/assets/multipurpose_bookshelf_slider/css/skin01.css /my_app/vendor/assets

Rails 3.1 plugin gem, dummy test app, rspec

阅读更多关于 Rails 3.1 plugin gem, dummy test app, rspec

问题 So Rails 3.1 comes with a little-known handy "rails g plugin new" generator, which gives you a skeleton suitable for a rails gem plugin. [http://guides.rubyonrails.org/plugins.html#or-generate-a-gemified-plugin] One of the useful things this does, is set things up conveniently for testing with Test::Unit. It gives you a basic dummy Rails app that your tests can run in the context of, to test 'engine' behavior that only functions in the copy of a Rails app. (it puts it in ./test/dummy). But

Rails Admin vs. ActiveAdmin [closed]

阅读更多关于 Rails Admin vs. ActiveAdmin [closed]

I've been looking into some rails admin plugins and came across these: https://github.com/gregbell/active_admin https://github.com/sferik/rails_admin https://github.com/thoughtbot/administrate (EDIT: added later) Any suggestions as to which one to go with. I would need it to support model associations and file uploads abilities. Harish Shetty I vote for rails_admin . I like its looks and the fact that out of the box all the models are available for administration. The history feature is quite useful too. Any project with Yehuda Katz as a mentor should be a safe bet. I personally think the two

execJs: 'Could not find a JavaScript runtime' but execjs AND therubyracer are in Gemfile

阅读更多关于 execJs: 'Could not find a JavaScript runtime' but execjs AND therubyracer are in Gemfile

I'm getting this error: rake aborted! Could not find a JavaScript runtime. See https://github.com/sstephenson/execjs , I have already spent more hours searching google then I am willing to admit. I believe this is an execJs bug. From all the posts, this is a very common issue with rails 3.1. A js runtime is now needed by what are now standard gems like coffee-script and sass. Most of these cases were resolved by adding the gems 'execjs' and 'therubyracer' to the app Gemfile, and then running 'bundle update' and/or 'bundle install'. But not for me. I guess I got lucky. I am running rails 3.1.3
