运行:Ruby 1.9.3p0(2011-10-30修订版33570)[x86_64-darwin11.2.0],Rails 3.2.0
我正试图通过各种协会的TIRE宝石进行弹性搜索.出于某种原因,我在TIRE导入或偶尔在视图上执行rake时不断收到以下错误/错误:
Daves-MacBook-Pro:outdoor dave$ rake environment tire:import CLASS=Gear FORCE=true

这是我的模型: GEAR
class Gear < ActiveRecord::Base
attr_accessible :title, :size, :price, :image_url, :sub_category_id, :user_id
belongs_to :user
belongs_to :sub_category
validates :title, presence: true

validates :user_id, presence: …我浏览了 Ruby Toolbox 和网络，很好奇是否有人知道 Rails 的 GEM 可以帮助您构建/创建预订系统（或教程）？类似于常见的预订网站，如 airbnb.com 或 expedia.com 等。
可以记录往返预订日期并显示可用性等的东西。我相信您已经明白了。
谢谢您的帮助。
当使用Twitter-Bootstrap的样式不正确地提交表单时,我试图简单地呈现flash消息.
我显然遗漏了一些东西,因为我一直收到以下错误:
TypeError in NewslettersController#create
can't convert Symbol into String
代码如下
视图
<div class="footer_newsletter_container">
<%= image_tag("envelope.png", :border=>0, :class => '') %> Sign up for our newsletter</br></br>
<%= simple_form_for Newsletter.new do |f| %>
<%= f.input :email, :label => false, :placeholder => 'Enter Your Email Address', class: "floatleft" %><%= f.button :submit, 'Submit', class: "btn floatleft" %>
<% end %>
<%= render "layouts/messages" %>
</div>
局部
<% flash.each do |name, msg| %>
<div class="alert alert-<%= name == :notice ? "success" : "error" %>">
<a …controller flash-message twitter-bootstrap ruby-on-rails-3.2
简单的问题,我如何使用太阳黑子搜索多个模型？...我正在使用太阳黑子与Rails,我似乎无法找到我如何搜索多个模型.我是否需要创建单独的控制器,还是可以将齿轮控制器与索引操作一起使用？
谢谢您的帮助.
(旁注:我发现stackoverflow上的一个问题非常类似于此但他们没有发布他们的代码.所以我为任何冗余道歉.)
我认为我有以下几点:
<div class="side_bar_search">
<%= form_tag gears_path, :method => :get do %>
<p>
<%= text_field_tag :search, params[:search] %>
<%= submit_tag "Search", :name => nil %>
<% end %>
</div>

我正在使用rails 3.2.8和Simple Form 2.0.2我试图以一种使用simpleform gem的形式实现它.在simpleform中,我使用关联方法来选择用户可以/可能属于的所有机构(数据库中的另一个表).
我一直试图通过组合2个轨道广播剧集#102和#258来拼凑它
我在我的gem文件中安装了gem
gem 'chosen-rails'
我把require项放在application.js中
//= require chosen-jquery
&application.css
*= require chosen
我已将调用放在users.js.coffee文件中
jQuery ->
$('#user_bankinst_name').chosen();
这是我正在尝试使用该插件的表单.这是"f.association"系列.
<%= simple_form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
<%= f.error_notification %>
<%= f.input :email, :required => true, :autofocus => true, :label => 'Username ( Your Email )', :placeholder => 'Email Address' %>

出于工作原因,我们使用机架式云服务器,将MySQL作为数据库.
设置乘客和Nginx让我感到沮丧.我已经关注Ryan的Railscasts 部署到vps和本教程.
我可以在服务器上安装ruby,mysql,passenger,Nginx,依赖项和rails.但是当我尝试启动Nginx时没有任何反应.当我说没有任何反应时,我的意思是我没有任何迹象表明它正在运行.我将浏览器指向IP地址,并在浏览器中收到标准错误"此网页不可用"错误.我查看了错误日志,它是空白的.我还没有部署我的应用程序......只是想看看Nginx的默认屏幕.
有任何想法吗？我猜测在配置Nginx时我缺少一个关键步骤我只是不知道它是什么.

我在我的模型中测试我的关联.我在Rails 3.2上,并且ruby 1.9.3p0(2011-10-30修订版33570)[x86_64-darwin11.2.0]当我输入"User.first"时它工作正常,返回第一个用户.当我键入"Gear.first"时,它也可以正常工作.但是,当我尝试通过用户访问"User.first.gears"之类的设备时,我不断收到以下错误:
