以管理员用户身份登录时，Rails验证失败

Question

我的Rails 3控制器中具有以下创建操作：

def create
    @registration = Registration.new(params[:registration])

    respond_to do |format|
      if @registration.save
        if @registration.orientation != nil #TODO replace this with an online? method
          format.html { render "scheduling_text.html.erb" }
          format.json { render json: @registration, status: :created, location: @registration }
          NsoMailer.registration_email(@registration).deliver
        else
          format.html { render "online_scheduling_text.html.erb" }
          format.json { render json: @registration, status: :created, location: @registration }
          NsoMailer.online_registration_email(@registration).deliver
        end
      else
        format.html { render action: "new" } 
        format.json { render json: @registration.errors, status: :unprocessable_entity } 
      end
    end
  end

我有自己的身份验证，当我未登录该应用程序时，我的验证会按预期进行。 那就是说我在上面代码的response_to块内。 但是，作为经过身份验证的用户，如果我尝试提交此表单，则验证失败，并显示此错误...

这似乎与路由有关吗？ 顺便说一句，我的路线看起来像...

/orientations/3/registrations/new

当表单最初加载时，并且验证失败后，路由为...

/registrations

...具有direction_id的隐藏值。 不确定登录后将与用户有什么关系。还请注意，在错误中有一行会重新加载用户。 我没有登录时没有看到该消息，所以这也可能是问题的一部分。

任何帮助表示赞赏！

这是app / views / registrations / new.html.erb

<h1>Register for New Student Orientation</h1>

<%= render 'form' %>

<%= link_to 'Back', orientations_path %>

<% if current_user %>
  </br>
  <%= link_to 'View Registrations', orientation_registrations_path %>
<%end%>

这是direction_registrations路线...

orientation_registrations GET    /orientations/:orientation_id/registrations(.:format)          registrations#index
                          POST   /orientations/:orientation_id/registrations(.:format)          registrations#create

Answer 1

您需要输入方向ID。 路径中的:orientation_id是rails期望的参数

而不是

<%= link_to 'View Registrations', orientation_registrations_path %>

你需要类似的东西

<%= link_to 'View Registrations', orientation_registrations_path( @registration.orientation) if @registration.orientation %>

您的控制器处理的方向可能为零，但是您拥有当前用户的视图代码假定该方向在那里。
