Question

我现在已经坚持这个问题太久了 - 所以希望有人能够告诉我我做错了什么。我试图在我的网站上添加一个简单的博客，通过远程使用rails ajax：true选项 - 除编辑帖子外，一切正常。

所有内容都是通过scaffold命令生成的，我的印象是它实际上应该正常工作。

如上所述，不起作用的是编辑帖子。

返回错误：

ActionController::UrlGenerationError in Posts#edit

Showing ~/webapp-rails4/app/views/posts/_form.html.erb where line #2 raised:

我的编辑链接：

<%= link_to 'Edit', edit_post_path(post.id, locale: I18n.locale), remote: true %>

控制器：

class PostsController < ApplicationController
  before_action :set_post, only: [:show, :edit, :update, :destroy]
  respond_to :js, :html

def edit
  logger.debug 'controller action edit'
  respond_with(@post)
end

def create
  @post = Post.new(post_params)
  @post.save
  #respond_with(@post)
end

def update
  @post.update(post_params)
  #respond_with(@post)
end

private
  def set_post
    @post = Post.find(params[:id])
  end

  def post_params
    params.require(:post).permit(:title, :body, :image)
  end

edit.js.erb（我在这里尝试了很多东西，这就是我现在所拥有的）：

alert('this is edit.js.erb');
$('#post<%= @post.id %> #editPostModal').append("<%= escape_javascript(render 'form', object: @post) %>");
$('#post<%= @post.id %> #editPostModal').foundation('reveal', 'open');

_form.html.erb（似乎是抛出错误的原因）：

<% logger.debug 'form being rendered'%>
<%= form_for @post, remote: true, :multipart => true, authenticity_token: true do |f| %>
  <% if @post.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@post.errors.count, "error") %> prohibited this post from being saved:</h2>

      <ul>
        <% @post.errors.full_messages.each do |msg| %>
          <li><%= msg %></li>
        <% end %>
      </ul>
    </div>
  <% end %>

<div class="field">
  <%= f.label :title %><br>
  <%= f.text_field :title %>
</div>
<div class="field">
  <%= f.label :body %><br>
  <%= f.text_area :body %>
</div>
<div class="field">
  <%= f.file_field :image %>
</div>
<div>
  <%= f.label :remote_image_url, "or image URL" %><br>
  <%= f.text_field :remote_image_url %>
</div>
<div class="actions">
  <%= f.submit %>
</div>
<% end %>

rake routes：

posts       GET    /:locale/posts(.:format)           posts#index {:locale=>/en|dk/}
            POST   /:locale/posts(.:format)           posts#create {:locale=>/en|dk/}

            PATCH  /:locale/posts/:id(.:format)       posts#update {:locale=>/en|dk/}
            PUT    /:locale/posts/:id(.:format)       posts#update {:locale=>/en|dk/}
            DELETE /:locale/posts/:id(.:format)       posts#destroy {:locale=>/en|dk/}

帖子中的ActionController :: UrlGenerationError＃edit没有路由匹配{：action =＆gt;＆＃34; show＆＃34;
