Question

我正在尝试使用此代码，但我不知道应该如何修复它。我得到的错误是

No route matches {:controller=>"generators", :action=>"new"} missing required keys: [:user_id]

用户

 has_many :generators
      has_many :results, :through=>:generators

发电机

has_one :result , :dependent => :destroy
  belongs_to :user

RESULT

belongs_to :generator
   belongs_to :user, :through=>:generators

这是我的主页：

 <%= link_to 'HOME', root_path, id:'home' %>
                     <%= link_to 'GENERATE RAPD PRIMER',new_user_generator_path, id:'new' %></li>
                     <%= link_to 'VIEW RESULT HISTORY', user_generators_path,id:'view'%></li>

每当some1点击GENERATE RAPD PRIMER时，他/她必须首先登录才可以使用它。所以在这个错误中我该如何修复它们？

Answer 1

在您的发电机控制器中，将@user设置为当前用户

@user = current_user 
#handle this however you want - define the user that is on the page

然后在视图中：

<%= link_to 'GENERATE RAPD PRIMER', new_user_generator_path(id:@user.id) %>

Answer 2

<强> generators_controller

@user = current_user

视图中的

<%= link_to 'GENERATE RAPD PRIMER',new_user_generator_path(@user), id:'new' %></li>
<%= link_to 'VIEW RESULT HISTORY', user_generators_path(@user),id:'view'%></li>

没有路由匹配{：controller =＆gt;“generators”，：action =＆gt;“new”}缺少必需的键：[：user_id]
