ruby-on-rails - # 的未定义方法 `get'

Question

有人知道如何解决这个问题吗？在 OSX 上，尝试让 RSpec 与 Rails 3.0.7 一起运行。完整详情请参见: https://gist.github.com/1017044

  it "renders buttons_widgets partial" do
    get :buttons_widgets
    response.should render_template("buttons_widgets")
  end

Answer 1

RSpec 不知道您的规范是 Controller 规范，因此您的示例无法访问 get 方法。

RSpec 2.x 假定 Controller 目录中的所有内容都是 Controller 规范。

这在 RSpec 3 中进行了更改:

File-type inference disabled by default

Previously we automatically inferred spec type from a file location, this was a surprising behaviour for new users and undesirable for some veteran users so from RSpec 3 onwards this behaviour must be explicitly opted into with:

RSpec.configure do |config|
  config.infer_spec_type_from_file_location!
end

https://www.relishapp.com/rspec/rspec-rails/docs/upgrade#file-type-inference-disabled

在 rspec-rails README :

Controller specs default to residing in the spec/controllers folder. Tagging any context with the metadata :type => :controller treats it's examples as controller specs.

为 RSpec 设置 Controller 上下文元数据的示例:

describe ToolsController, :type => :controller do
    # ...
end
