我正在尝试从帖子控制器内的评论控制器呈现 _new.html.erb 部分。
我的评论资源嵌套在我的帖子资源中
路线.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'
我的评论控制器中的 _new.html.erb 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 show.html.erb 文件中，当我使用以下内容时：
<%= render 'comments/new' %>
_new 部分表单出现，但是当我发布时，我收到错误：
No route matches [POST] "/comments"
如果我在 show.html.erb 中使用以下行
<%= render new_post_comment %>
我得到错误：
undefined local variable or method `new_post_comment'
以下是我的 rake 路线
