I m试图从一个员额控制员内部的一个评论控制员中拿出一个部分。

我的评论资源用于我的员额资源。

路线。

  resources :users, :only => [:show, :create, :new]

  resources :posts do
    resources :comments
    resources :memorybooks
  end

  root to:  static_pages#home 

  match  /channel ,    to:  static_pages#channel 
  match  login , to:  static_pages#login 
  match  /posts , to:  posts#new 
  match  /users , to:  users#new 

我——新,html。

   <%= form_for([@post, @comment]) do |f| %>

      <%= f.label :comment %>
      <%= f.text_field :comment %>

      <p>
      <center>
      <%= f.submit "Submit", class: "btn btn-large btn-primary" %>
      </center>
    <% end %>

我的评论控制器方法:

def create
@post = Post.find_by_id(params[:id])
@comment = @post.comments.build(params[:comment])
    if @comment.save
    redirect_to @current_post
else
    render  / 
end
end

在我的证言中,当我使用以下文字时,我就使用了:

<%= render  comments/new  %>

“新部分”形式出现,但当我担任职务时,我发现错误:

No route matches [POST] "/comments"

而且,如果我用以下线显示的话。

<%= render new_post_comment %>

我发现错误:

undefined local variable or method `new_post_comment 

下面是我的航道。
