提交我的表单 (_reply_form.html.erb) 时，我收到此错误：
Routing Error
No route matches [POST] "/responses/replies/4"
Try running rake routes for more information on available routes.
这就是我的架构的设置方式：产品有很多响应。响应有很多回复。
我知道我需要表单来提交到这条路线，但我无法做到这一点：
response_replies POST /responses/:response_id/replies(.:format) replies#create
_reply_form.html.erb：
<%= form_for(@reply, :url => response_reply_path([@response, @reply])) do |f| %>
<%= render 'common/form_errors', object: @reply %>
<%= f.label :body, "Your Reply" %>
<%= f.text_area(:body, :rows => 10, :class => "field span6") %>
<%= f.submit "Post Reply", :class => "block" %>
<% end %>
_response.html.erb：
<%= render 'replies/reply_form', {:response => @response, :reply => @reply} %>
产品/show.html.erb：
<% if @offering.responses.any? %>
<%= render @offering.responses %>
<% else %>
<p>This offering has no responses yet.</p>
<% end %>
响应控制器.rb：
class ResponsesController < ApplicationController
before_filter :auth, only: [:create]
def show
@offering = Offering.new
@response = Response.new
@reply = Reply.new
end
def create
@offering = Offering.find(params[:offering_id])
# now that we have our offering we use it to
# build a response with it
@response = @offering.responses.build(params[:response])
# now we get the user who posted the response
@response.user = current_user
if @response.save
flash[:success] = 'your response has been posted!'
redirect_to @offering
else
@offering = Offering.find(params[:offering_id])
render 'offerings/show'
end
end
end
路线.rb：
resources :offerings, except: [:new] do
# makes it easier for us to display
# forms for responses on the offering show page
# allows us to have access to the
# offering that the response is associated to
resources :responses, only: [:create]
end
resources :responses, except: [:new] do
resources :replies, only: [:create]
end
rake 路线产生这个：
