ruby-on-rails - 相同的控制器和库类名

Question

有两个相似的类名（一个在 lib 中，一个在控制器中）是错误的吗？

myapp/lib/company/api.rb

module Company
  class Api
    include HTTParty

    base_uri "#{API_CONFIG['scheme']}://#{API_CONFIG['host']}"
    digest_auth API_CONFIG['email'], API_CONFIG['key']

    DEFAULT_OPTIONS = {
      limit: 1
    }

  #...
end

myapp/app/controllers/api/something_controller.rb

class Api::SomethingController < ApplicationController
  def index
    # TODO: Verify q
    q = params[:q]

    @result = Company::Api.new().send("get_sdf_#{q}",
                                   rn: "123",
                                   limit: params[:limit])


  #...
end

Answer 1

这里没有两个相同的命名类。一个类被命名Api，在模块中定义Company。另一个是SomethingController在 module 中定义的类Api。

我想你忘了定义 module Company。

添加一个以lib/Company.rb内容命名的文件

module Company
end

现在它应该可以工作了。
