渲染嵌套部分新形式

Question

我试图呈现一个_new.html.erb部分从posts控制器内部的意见控制器。

我的评论资源被嵌套在我的职位资源

的routes.rb

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_new.html.erb在我的意见控制器部分：

<%= 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 %> 

我的评论控制器的方法：

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show.html.erb文件，当我使用以下命令：

<%= render 'comments/new' %> 

出现_new部分的形式，但是当我后，我得到的错误：

No route matches [POST] "/comments" 

如果我使用下面的行show.html.erb

<%= render new_post_comment %> 

我得到的错误：

undefined local variable or method `new_post_comment'
