Question

我使用netzke + rails 4 + extjs-4.2.1遇到了一种奇怪的行为每次第一次加载页面时都会显示div，但在刷新页面之前不会加载网格。我无法使用rails 3 + netzke 0.8 + extjs-4.1重现错误。这可能是一个netzke错误吗？我使用浏览器控制台，没有显示错误。

我目前正在使用此版本的netzke：

gem "netzke-core", "~> 0.10.0.rc2"
gem "netzke-basepack", "~> 0.10.0.rc2"

和Rails 4.0.2与extjs-4.2.1

我的application.html.erb

<!DOCTYPE html>
<html>
<head>
    <title>Railroad</title>
    <%= stylesheet_link_tag "application", media: "all", "data-turbolinks-track" => true %>

            <hr/>
        </div>
        <div style="float: left;">
            <% if I18n.locale == I18n.default_locale %>

            <% else %>
                <%= link_to "English", :locale=>'en'%>
            <%end%>
        </div>
        <div style="float: right;">
            <% if user_signed_in? %>
                <%= link_to (t :sign_out), destroy_user_session_path, :method => :delete %>
            <% end %>
        </div>
    </div>
    <div id="main-content">

    </div>
    <div id="footer">

    </div>
</div>
</body>
</html>

我的欢迎/ index.html.erb

<h2><%= t :post_option %></h2>
<ul>
    <li><%= link_to (t :post_list),  posts_path%></li>
    <li><%= link_to (t :post_new),   new_post_path%></li>
</ul>

我的帖子/ index.html.erb

<h2>TEST</h2>
<%= netzke :posts, height: 400 %>

<br/>
<%=  link_to (t :back), root_path %>

我的routes.rb

Railroad::Application.routes.draw do

  devise_for :users, :controllers => {:registrations => "registrations", :omniauth_callbacks => "omniauth_callbacks"}

  resources :posts do
    resources :comments
  end

  netzke
  root "welcome#index"

end

我的模特post.rb

class Post < ActiveRecord::Base
  has_many :comments, dependent: :destroy
  validates :title, presence: true, length: { minimum: 5 }

  private
  def post_params
    params.require(:post).permit(:title, :text)
  end
end

我的组件/ posts.rb

class Posts < Netzke::Basepack::Grid
  def configure(c)
    super
    c.model = "Post"
    c.columns = [
        :title,
        :text
    ]
    c.prohibit_update = true
    c.prohibit_delete = false
  end
end

感谢您的帮助。

更新

问题似乎与NetzkeController有关，当我点击link_to时，它会将我发送到带有网格的页面，但NetzkeController未使用0.10.0.rc2执行，因此在刷新页面之前，网格没有加载，但如果我在0.8中执行相同的场景，则调用它NetzkeController并加载网格。

以下是netzke 0.8和0.10.0rc2

您好我终于解决了在呈现页面的所有链接上指定方法的问题，这很奇怪因为netzke 0.8.0不需要这个可能会在官方发布时解决。

这是我的新application.html.erb，而不是语言环境中的link_to。

<!DOCTYPE html>
<html>
<head>
    <title>Railroad</title>
    <%= stylesheet_link_tag "application", media: "all", "data-turbolinks-track" => true %>
    <%= javascript_include_tag "application", "data-turbolinks-track" => true %>
    <%= load_netzke %>
    <%= csrf_meta_tags %>
</head>
<body>
<div id="wrap">
    <div id="header">
        <div>
            <h1>Demo</h1>
            <hr/>
        </div>
        <div style="float: left;">
            <% if I18n.locale == I18n.default_locale %>
                <%= link_to "Español", {:locale=>'es'}, :method => :get%>
            <% else %>
                <%= link_to "English", {:locale=>'en'}, :method => :get%>
            <%end%>
        </div>
        <div style="float: right;">
            <% if user_signed_in? %>
                <%= link_to (t :sign_out), destroy_user_session_path, :method => :delete %>
            <% end %>
        </div>
    </div>
    <div id="main-content">
        <%= render 'layouts/messages' %>
        <%= yield %>
    </div>
    <div id="footer">
        <hr/>
    </div>
</div>
</body>
</html>

这是我的新欢迎/ index.html.erb

<h2><%= t :post_option %></h2>
<ul>
    <li><%= link_to (t :post_list),  posts_path, :method => :get%></li>
    <li><%= link_to (t :post_new),   new_post_path%></li>
</ul>

网格在第一页加载时不会呈现（Netzke + Rails 4 + extjs）
