我正在尝试为插件“foobar”开发测试,修改一些标准的Rails助手.在vendor / plugins / foobar / test / foobar_test.rb中,我有以下内容:
- # create the test model
- class Thing < ActiveRecord::Base
- end
- # create the test controller,which renders the included index template
- class ThingsController < ActionController::Base
- def index
- @things = Thing.all
- format.html { render(:file => 'index') }
- end
- def destroy
- @thing = Thing.find(params[:id])
- @thing.destroy
- format.html { render(:file => 'index') }
- end
- end
- # confirm that the test environment is working correctly
- class ThingsTest < ActiveSupport::TestCase
- test "model is loaded correctly" do
- assert_kind_of Thing,Thing.new
- end
- end
- # confirm that the controller and routes are working correctly
- class ThingsControllerTest < ActionController::TestCase
- test "should load index" do
- with_routing do |set|
- set.draw do
- resources :things,:only => [:index,:destroy]
- end
- get :index
- assert_response :success
- end
- end
- end
当我运行rake时,我得到以下输出:
- test_should_load_index(ThingsControllerTest):
- NameError: undefined local variable or method `_routes' for ThingsController:Class
知道我做错了什么阻止我访问路线?我已经在这里待了好几天并且搜索了很多文档,但都无济于事.谢谢您的帮助!
解决方法
我使用Ruby 1.9.2在Rails 3.1.0.rc1上工作,遵循
“The Basics of Creating Rails Plugins” Rails指南并在因不兼容而爆炸时更正代码.
我开始跑步:
- Code$rails new tester
- Code$cd tester
- tester$rails generate plugin foobar --with-generator
- # vendor/plugins/foobar/init.rb
- require 'foobar'
- # vendor/plugins/foobar/lib/foobar.rb
- %w{ models controllers helpers }.each do |dir|
- path = File.join(File.dirname(__FILE__),'app',dir)
- $LOAD_PATH << path
- ActiveSupport::Dependencies.autoload_paths << path
- ActiveSupport::Dependencies.autoload_once_paths.delete(path)
- end
- # I'm not entirely sure this is the best way to add our plugin's views
- # to the view search path,but it works
- ActionController::Base.view_paths =
- ActionController::Base.view_paths +
- [ File.join(File.dirname(__FILE__),'views') ]
- <!-- vendor/plugins/foobar/lib/app/views/things/index.html.erb -->
- <h1>Listing things</h1>
- <table>
- <tr>
- <th>Name</th>
- <th></th>
- </tr>
- <% @things.each do |thing| %>
- <tr>
- <td><%= thing.name %></td>
- <td><%= link_to 'Destroy',thing,confirm: 'Are you sure?',method: :delete %></td>
- </tr>
- <% end %>
- </table>
- # vendor/plugins/foobar/test/database.yml
- sqlite:
- :adapter: sqlite
- :dbfile: vendor/plugins/foobar/test/foobar_plugin.sqlite.db
- sqlite3:
- :adapter: sqlite3
- :database: vendor/plugins/foobar/test/foobar_plugin.sqlite3.db
- postgresql:
- :adapter: postgresql

- :password: postgres

- # vendor/plugins/foobar/test/schema.rb
- ActiveRecord::Schema.define(:version => 0) do
- create_table :things,:force => true do |t|
- t.string :name
- t.datetime :created_at
- t.datetime :updated_at
- end
- end
- # vendor/plugins/foobar/test/test_helper.rb
- ENV['RAILS_ENV'] = 'test'
- ENV['RAILS_ROOT'] ||= File.dirname(__FILE__) + '/../../../..'
- require 'test/unit'
- require File.expand_path(File.join(ENV['RAILS_ROOT'],'config/environment.rb'))
- def load_schema
- config = YAML::load(IO.read(File.dirname(__FILE__) + '/database.yml'))
- ActiveRecord::Base.logger = Logger.new(File.dirname(__FILE__) + "/debug.log")
- db_adapter = ENV['DB']
- # no db passed,try one of these fine config-free DBs before bombing.
- db_adapter ||=
- begin
- require 'rubygems'
- require 'sqlite'
- 'sqlite'
- rescue MissingSourceFile
- begin
- require 'sqlite3'
- 'sqlite3'
- rescue MissingSourceFile
- end
- end
- if db_adapter.nil?
- raise "No DB Adapter selected. Pass the DB= option to pick one,or install sqlite or sqlite3."
- end
- ActiveRecord::Base.establish_connection(config[db_adapter])
- load(File.dirname(__FILE__) + "/schema.rb")
- require File.dirname(__FILE__) + '/../init'
- end
- load_schema
- # vendor/plugins/foobar/test/foobar_test.rb
- require File.dirname(__FILE__) + '/test_helper'
- # create the test model
- class Thing < ActiveRecord::Base
- end
- # create the test controller,which renders the included index template
- class ThingsController < ActionController::Base
- def index
- @things = Thing.all
- respond_to do |format|
- format.html # index.html.erb
- end
- end
- def destroy
- @thing = Thing.find(params[:id])
- @thing.destroy
- respond_to do |format|
- format.html { redirect_to things_url }
- end
- end
- end
- # confirm that the test environment is working correctly
- class ThingsTest < ActiveSupport::TestCase
- test "schema has loaded correctly" do
- assert_equal [],Thing.all
- end
- test "model is loaded correctly" do
- assert_kind_of Thing,:destroy]
- end
- get :index
- assert_response :success
- end
- end
- end
最后,我们的测试通过:
