问题 I am working with Ruby On Rails for the last year. But, could not work on Unit Testing. Now I have to write a unit testing code. Which testing framework is good and why? Is there any good tutorial for this? My system configuration: Ruby 1.9.2, Rails 3, Ubuntu 10 回答1: The first tip is: Try upgrading to Rails 5.x. This is good practice to always leave your system clean and faultless from third parties. Your greatest friend will always be the rails documentation: http://guides.rubyonrails.org/v3

问题 I'm trying to install a couple of different plugins for my rails 3 app. I cd to '/vendor/plugins/', then type git clone the_git_src_url . I see the files in the /vendor/plugins/ directory. However when I try to use any of the tags provided by the plugin I get uninitialized constant ContentsController::HTMLToTextileParser PriceTag and html2textile are the two plugins I'm trying to use. This is what triggers the error above: <%= PriceTag.html_to_textile(@content.desc) %> I'm working in

问题 I want to define a class method that has access to a local variable. So this would be different for each instance of the class. I know you can make a class method dynamic with lambda like when you use it with named_scope. But can this be done for values that are specific to an instance? In detail it is the has_attached_file method for the paperclip plugin in rails. I want to pass a lambda for the styles hash so that the image styles can be based off of attributes of the object stored in the

问题 There are a lot of role-based authorization plugins out there. They work great when you know in advance what the roles are going to be. For example, if I know I'm going to have administrators, super_users, and not_so_super_users. What I really want is to be able to create custom roles and assign that role to a user. At this point, I am simply wanting to block access to controllers / actions based on a user's custom role. Roles will consist of permissions. For example, Jane Doe can add and

问题 Are there any resources or documentation for developing Rails plugins? I'm using other plugins as examples, but it's hard to know if I'm doing something wrong, or if there's another way to do something. All I can find are old blog posts.

问题 While crafting the Passenger-Monit plugin, I thought that it'll be most appropriate to use the initializer, i.e. module PassengerMonit class Railtie < Rails::Railtie initializer "my_plugin.some_init_task" do # my initialization tasks end end end However, for some reason the code in the block was never executed. I finally made a work-around with config.before_initialize {} but I'm curious, why the initializer wasn't executed. What could have prevented it from running? 回答1: In your gemfile, did

问题 I'm creating a new plugin for a jruby on rails application that will eventually be turned into a gem. Inside my plugin I have controllers, helpers and views. For my views I'd like to use Haml. The problem is that I can't seem to get it to recognize that they are haml templates. Is it even possible to do this? Is there a way for a plugin to have Haml as a dependency for its view? And by that I mean, I intend for the plugin that I'm creating to have a view created by the plugin, that can be

问题 I'm using dwilkie's foreigner plugin for rails. I have a table creation statement that looks like: create_table "agents_games", :force => true, :id => false do |t| t.references :agents, :column => :agent_id, :foreign_key => true, :null => false t.references :games, :column => :game_id, :foreign_key => true, :null => false end However, this generates the following SQL: [4;35;1mSQL (2.7ms)[0m [0mCREATE TABLE "agents_games" ("agents_id" integer NOT NULL, "games_id" integer NOT NULL) [0m I want
