Rails AJAX 500错误

我正在完成关于Rails的教程 - 但是该教程是用Rails 2编写的，而且因为我有Rails 3，我不得不将所有内容都转换。Rails AJAX 500错误

我有一个谷歌地图，当你点击它时，你应该弹出一个新的标记和输入数据的表单。当我点击地图时，标记出现，但没有输入数据的表单。任何帮助将非常感激！

我猜它与ajax有关？当我点击地图上的任何地方尝试输入新数据时，Web控制台给我一个500内部服务器错误。不知道我要去哪里错了！

下面是 '新' 的动作的控制器编码：

def new 
    @incident = Incident.new 

    respond_to do |format| 
    format.html { 
     @incident.latitude=params['latitude'] 
     @incident.longitude=params['longitude'] 
     render :partial=>'new', :locals=>{:incident=>@incident} 
    } 
    format.xml { render :xml => @incident } 
    end 
end

索引视图：

<h1>Listing incidents</h1> 

<%= render(:partial=>"map", :locals=>{:data=>"/incidents.xml", 
    :full_page=>true, :show_action=>'show', :new_action=>'new'}) %>

和 '新' 部分：

<h1>New incident</h1> 
<% form_for(incident, :update=>'map_info'), :remote => true do |f| %> 
<p> 
    <%= f.label :mountain %> <%= f.text_field :mountain %> 
</p> 
<%= f.hidden_field :latitude %> 
<%= f.hidden_field :longitude %> 
<p> 
    <%= f.label :when %> <%= f.datetime_select :when %> 
</p> 
<p> 
    <%= f.label :title %> <%= f.text_field :title %> 
</p> 
<p> 
    <%= f.label :description %><br/> 
    <%= f.text_area :description, :rows=>3 %> 
</p> 
<p> 
    <%= f.submit "Create" %> 
</p> 
<% end %>

这里的堆跟踪（当我加载页面，然后点击地图上的新事件）：

这听起来像是在某些Ajax调用中出现HTTP 500错误。请将日志文件中的实际错误消息与堆栈跟踪一起发布。 –

以下是错误：[14：29：07.279] GET http：// localhost：3000/incidents/new？latitude = 51.98036694779745＆longitude = -93.515625 [HTTP/1.1 500 Internal Server Error 322ms] – ecs

请在您的Rails日志文件[RAILS_ROOT/log/development.log）获取确切的错误消息和回溯，并将其添加到原始问题中。 –

根据错误：

其","从:remote => true的面前，form_for(incident, :update=>'map_info')后面。删除它

好吧，让我们重新编码它。尝试：

<%= form_for incidents_url, :remote => true do |f| %>

你要添加新的文件在事件称为new.js.erb（incidents/new.js.erb）。通常它会被称为create.js.erb，但是您使用的是new action，而不是创建。

在那个文件里面，你写了更新div的jQuery代码。你

$(".class_name_of_div").prepend("<%= @incident.which_ever_attribute_you_want %>");

可能还需要改变你的控制器位：

def new 
    @incident = Incident.new 
    @incident.latitude = params[:latitude] 
    @incident.longitude = params[:longitude] 
    @incident.save 

    respond_to do |format| 
    format.html 
    format.js 
    end 
end

更改部分太：

<%= render 'incidents/map', :incident => @incident %>

告诉我是怎么回事。

我试过了，它仍然不起作用。然后它会抱怨'：remote'前面的冒号。它似乎也给控制器中的'新'部分和'新'动作提供了错误，但是看到这是从教程中给出的'答案代码'的代码，我不知道为什么它不工作！ – ecs

是的！非常感谢！！我将如何编辑以包含：update =>'map_info'？ – ecs

你想用map_info做什么？ - 我从来没有使用轨道2 ..我可以告诉你如何在轨道3中做到这一点:) – Dol
