元搜索“NilClass:Class 的未定义方法‘model_name’"用于全球酒吧搜索 [英] MetaSearch "undefined method `model_name' for NilClass:Class" for global bar search

问题描述

我正在使用 Ernie 出色的 MetaSearch，但遇到了一个烦人的问题.

在我的 application.html.erb 中，我有一个搜索字段，就像 StackOverflow 页面顶部的这个一样.

<%= form_for @search, :url =>vagas_path 做 |f|％＞<%= f.text_field :titulo_or_empresa_user_username_contains %><%= f.submit "", :class =>"搜索按钮", :name =>提交"%><%结束%>

问题是我没有在所有控制器的所有操作中初始化@search，所以当我不在 Vagas#index 时，我收到NilClass:Class 的未定义方法`model_name'"消息.

最好的解决方案是什么?

============================================

解决方案

<%= form_tag vagas_path, :method =>:get, :id =>'vaga_search' 做 %><%= text_field_tag '搜索[titulo_or_empresa_user_username_contains]' %><%= submit_tag "", :class =>"搜索按钮", :name =>"提交", :id =>'search_submit' %><%结束%>

解决方案

如果 @search 设置为 nil，您将收到此错误.确保不是这种情况.

I'm using fantastic MetaSearch by Ernie, but I'm having an annoying issue.

In my application.html.erb I have an search field, just like this one on top of StackOverflow page.

<%= form_for @search, :url => vagas_path do |f| %>
    <%= f.text_field :titulo_or_empresa_user_username_contains %>
    <%= f.submit "", :class => "search-button", :name => "submit" %>
<% end %>

The problem is that I don't have @search initialized in all actions of all controllers, so when I'm not at Vagas#index I get the "undefined method `model_name' for NilClass:Class" message.

What's the best solution for that?

============================================

Solution

<%= form_tag vagas_path, :method => :get, :id => 'vaga_search' do %>
    <%= text_field_tag 'search[titulo_or_empresa_user_username_contains]' %>
    <%= submit_tag "", :class => "search-button", :name => "submit", :id => 'search_submit' %>
<% end %>

解决方案

You would get this error if @search is set to nil. Ensure that this is not the case.
