渲染部分表单时路由错误 [英] Routing error in rendering partial form

问题描述

我正在制作一个项目，其中有一个类 online_score ，其中一个属性名为 url of online_score_url 对象。我现在做的是以下内容。代码可能有点肮脏，因为我不断尝试新事物，但只要我得到它的工作，我会清理它。
views / online_score / new：

 < h3>连结：< / h3> 
< div class =urlInput> 
 <％f.fields_for：url do | f | ％GT; 
< div class =inputset> 
<％= f.label：url％> <％= f.url_field：url，：value => http://www.google.be ％> 
<％= f.label：description％> <％= f.text_field：description％> 
 <％= link_to_remove_fieldsremove，f％> 
< / div> 
<％end％> 
 <％= add_url_link添加另一个链接，f％> #works罚款，如果我删除这条规则
< / div> 
  

views / online_score / _online_score_url_fields：

 <％= f.fields_for：item do | b | ％GT; 
< div class =inputset> 
<％= b.label：url％> <％= b.url_field：url，：value => http://www.google.be ％> 
<％= b.label：description％> <％＃= b.text_field：description％> 
<％= link_to_remove_fieldsremove，b％> 
< / div> 
<％end％> 
  

现在我的问题是我希望能够为动态添加输入， online_score_url 我试图用JQuery做的对象。我尝试通过渲染部分内容来实现这一点：$ b​​ $ b helpers / online_scores_helper.rb：

  def add_url_link（name ，f）
 link_to_function name do | page | 
 item = OnlineScoreUrl.new（，）
 instrument_online_score = render：partial => online_score_url_fields，：locals => {：f => f，：item => item} 
 
页面<< ％{
 $（'。links'）。append（＃{escape_javascript online_score_url}）; 
} 
 end 
 end 
  

现在的问题是它给出以下错误：

ActionController :: RoutingError in Online_scores＃new

显示/home/kvhooreb/jenna_vopro/score/app/views/online_scores/new.html.erb其中line>＃22 raise：

是什么原因导致的有人有想法吗？
感谢您的时间。

解决方案

根据您提供的信息，我将假设问题在 app / helpers / online_scores_helper.rb 中，具体来说，这一行：

  $（'。links'）。append（＃{escape_javascript online_score_url}）; 
  

如果您已经为online_scores定义了标准资源，则可以引用特定的在线分数记录 online_score_url（online_score.id），或参考在线分数列表 online_score_urls 。

online_score_url ，为单数，通常需要一个 id 来呈现路线。没有它，你会得到错误信息：

I'm making a project for which I have a class online_score which has as one of its attributes an array called url of online_score_url objects. What I did up to now is the following. The code might be a little dirty because I'm constantly trying new things, but as soon as I get it working, I'll clean it up. views/online_score/new:

<h3>Links: </h3>
<div class="urlInput">
<%f.fields_for :url do |f| %>
<div class="inputset">
<%= f.label :url %>  <%= f.url_field :url, :value => "http://www.google.be"%>
<%= f.label :description %>  <%= f.text_field :description %>
<%= link_to_remove_fields "remove", f %>
</div>
<%end %>
<%= add_url_link "Add Another link", f %> #works fine if I remove this rule
</div>

views/online_score/_online_score_url_fields:

<%= f.fields_for :item do |b| %>
<div class="inputset">
<%= b.label :url %>  <%= b.url_field :url, :value => "http://www.google.be"%>
<%= b.label :description %>  <%#= b.text_field :description %>
<%= link_to_remove_fields "remove", b %>
</div>
<% end %>

My problem is now that I want to be able to dynamically add inputs for online_score_urlobjects which I try to do with JQuery. I try to do this by rendering the partial like so: helpers/online_scores_helper.rb:

def add_url_link(name, f)
link_to_function name do |page|    
  item = OnlineScoreUrl.new("", "")
  instrument_online_score = render :partial => "online_score_url_fields", :locals => {:f => f, :item => item}

  page << %{
    $('.links').append("#{ escape_javascript online_score_url }");
  }
end
end

The problem now is that it gives the following error:

ActionController::RoutingError in Online_scores#new

Showing /home/kvhooreb/jenna_vopro/score/app/views/online_scores/new.html.erb where line >#22 raised:

Now I have no clue what causes this. Does anyone have an idea? Thanks for your time.

解决方案

Based off the information you've provided, I am going to assume the problem is in app/helpers/online_scores_helper.rb, specifically, this line:

$('.links').append("#{ escape_javascript online_score_url }");

If you've defined a standard resource for online_scores, you either are referring to a specific online score record online_score_url(online_score.id), or referring to the list of online scores online_score_urls.

online_score_url, being singular, normally would expect an id in order to render the route. Without it, you would get the error message:

"No route matches {:action=>"show", :controller=>"online_scores", :locale=>:en} Extracted source (around line #22):"
