Rails 4-路线和路径

Question

我正在尝试学习如何在Rails 4中使用路线和路径。

我有一个称为组织请求的模型。

我通过routes.rb输入了以下路由：

resources :organisation_requests do #, only: [ :index, :new, :create ]
    member do 
      put "requested" => "organisation_requests#requested", as: :request_approval #what does this mean?
      put "approved" => "organisation_requests#requested", as: :approved #what does this mean?
      put "rejected" => "organisation_requests#rejected", as: :not_approved #what does this mean?
      put "removed" => "organisation_requests#removed", as: :removed #what does this mean?
    end
  end

在我的组织请求控制器中，我有：

 def approved
    organisation_request = OrganisationRequest.find(params[:id])
    authorize @organisation_request
    if organisation_request.state_machine.transition_to!(:approved)
      flash[:notice] = "You've been added as a member. Welcome aboard."
      format.html { redirect_to :index }
      # format.json { render :show, status: :ok, location: @project }
      # redirect_to action: :show, id: project_id
      # add mailer to send message to owner that article has been approved
    else
      flash[:error] = "You're not able to manage this organisation's members"
      redirect_to(profile_path(current_user.profile))
      # redirect_to action: :show, id: project_id
    end
  end

在我的组织的请求索引中，我正在尝试建立一条允许用户批准请求的路径：

<% @organisation_requests.each do |orgReq| %>

              <tr>
                <td>
                  <%#= link_to orgReq.profile.user.full_name, organisation_request.profile_path(organisation_request.profile.id) %>
                </td>
                <td>
                  <%= orgReq.created_at.try(:strftime, '%e %B %Y') %>
                </td>
                <td>
                  <%= orgReq.current_state %>
                </td>
                <td>
                  <% if policy(orgReq).approved? %>    
                      <%= link_to "APPROVE", request_approval_path(@organisation_request), :class=>'btn btn-info', method: :put %>
                  <% end %>


                </td>  

              </tr> 
            <% end %> 

保存所有内容并进行尝试时，我希望批准按钮可以正常工作。 相反，我收到一条错误消息：

undefined method `request_approval_path' for #<#<Class:0x007fa470f72968>:0x007fa474d17a98>

我不确定我要去哪里错了？

Answer 1

Rails 4中的rake有一个routes命令，通过该命令，您可以查看由于routes.rb文件内容而导致的所有URL路径帮助程序都被命名了。

从项目根目录开始， rake routes | grep request_approval是什么？ rake routes | grep request_approval收益？

Answer 2

这是因为方法名称是“ request_approval_organisation_request”。 您正在将该路由称为控制器内部。 如果添加

 get 'exit', to: 'sessions#destroy', as: :logout

在您的资源中：organisation_requests您将获得

logout_organisation_request_path

等等
