我正在尝试在模型程序和学生之间建立“友谊”。我用 has_many 做：通过模型关系。在关系控制器中，我创建了动作，它应该在友谊发生后重定向另一个页面。

因此，在学生展示视图中，我有 link_to 请求友谊。我以为我可以进入学生展示页面，但是当我尝试进入学生展示视图到另一个页面时，它会将我从学生索引重定向。所以我实际上无法进入学生节目，它只是将我重定向到其他页面。

为什么会这样？单击“请求友谊”后，我希望从学生显示视图重定向到其他模型页面。

学生 show.html.erb

 <%= link_to "Request friendship with #{@student.name}",
 { :controller => "relationship", :action => "create",
 :id => @student.name },
 :confirm => "Send friend request to #{@student.name}?" %>

路由.rb

 match "/students/:id" => "relationships#create"

更新

关系控制器

def create
  Relationship.request(@prog, @student)
  flash[:notice] = "Friend request sent."
  redirect_to prog_url
end

不确定我完全理解@prog 应该是什么，但这是要走的路

def create
  @student = Student.find_by_id(params[:id])
  @prog = Programme.find_by_id(params[:prog]) #You need to fill this in
  Relationship.request(@prog, @student)
  flash[:notice] = "Friend request sent."
  redirect_to @student # Or @prog, or whatever you'd like
end

您可能还需要将 prog.id 传递给控制器​​，例如：

match "/students/:id/:prog" => "relationships#create"

并添加

<%= link_to "Request friendship with #{@student.name}",
 { :controller => "relationship", :action => "create",
:id => @student.name, :prog => @student.current_programme },
# I don't know how you differ programmes, you'd have to work this one out  
:confirm => "Send friend request to #{@student.name}?" %>
