Question

我正在尝试在我的某个模型中实现搜索。我正在使用gem“mongoid_search”，我在搜索时将它与railscast＃240混合使用。它似乎返回一个空数组，我无法弄清楚为什么。有人能指出我正确的方向吗？

我的模型看起来像这样：

include Mongoid::Search 

attr_accessible :twitterUsername, :twitterName, :twitterLocation, :twitterDescription, :projects

def self.search(search)
    if search
        search_in :twitterUsername, :twitterName, :twitterLocation, :twitterDescription, :projects
    else
        scoped
    end
end

我的控制器：

def index
    @users = User.search(params[:search])

    respond_to do |format|
        format.html # index.html.erb
        format.json { render json: @users }
    end
end

我的观点：

<%= form_tag users_path, :method => 'get', :id => "users_search" do %>
    <p>
        <%= text_field_tag :search, params[:search] %>
        <%= submit_tag "Search", :name => nil %>
    </p>
<% end %>

我也在模型中定义了twitterUsername（对于错误的命名约定）：

field :provider, :type => String
field :uid, :type => String
field :twitterName, :type => String
field :twitterUsername, :type => String
field :twitterAvatar, :type => String
field :twitterUrl, :type => String
field :twitterPortfolioUrl, :type => String
field :twitterLocation, :type => String
field :twitterDescription, :type => String
field :email, :type => String
field :description, :type => String
field :portfolioUrl, :type => String
field :watchers, :type => Integer
field :inspirations, :type => Integer
field :invitees, :type => Integer
field :shot, :type => String
field :remote_image_url, :type => String
field :hireMe, :type => Boolean
field :projects, :type => Integer
key :twitterUsername


def self.create_with_omniauth(auth)
    create! do |user|
        user.provider = auth['provider']
        user.uid = auth['uid']
        if auth['info']
            user._id = auth['info']['nickname'] || ""
            user.twitterName = auth['info']['name'] || ""
            user.twitterUsername = auth['info']['nickname'] || ""
            user.twitterAvatar = auth['info']['image'] || ""
            user.twitterUrl = auth['info']['urls']['Twitter'] || ""
            user.twitterPortfolioUrl = auth['info']['urls']['Website'] || ""
            user.twitterLocation = auth['info']['location'] || ""
            user.twitterDescription = auth['info']['description'] || ""
        end
    end
end

如果我统计用户，它似乎返回一个用户（这是正确的，因为我是现在唯一注册的用户）：

<% if @users.count > 0 %>
  <%= @users.count %>
<% end %>

如果我这样做：

<% if @users.count > 0 %>
  <%= @users.twitterUsername %>
<% end %>

它给了我这个错误：用户：类的未定义方法`twitterUsername'。

当我尝试运行tail log / development.log时，它给出了一个错误：

± % tail log/development.log

如果我运行搜索，我会在控制台中收到此信息：

Answer 1

正如我所看到的，问题是mongoid-search添加了一个名为＆＃34; _keywords＆＃34;保存时的文档。然后它根据＆＃34; _keywords＆＃34;

搜索文档

因此，您实际上需要重新索引集合。试试这个：

添加到用户模型

field :reindexed, type: Boolean, default: false

运行以下

User.where(reindexed: false).each {|u| u.reindexed = true; u.save}

然后当你搜索时，应该很高兴。

Answer 2

我最终没有在if / else语句中进行搜索。结束了：

search_in :twitterUsername, :twitterName, :twitterLocation, :twitterDescription

就这么简单。我正在使用索引进行搜索，因为我没有将其用于其他任何内容。

使用mongoid_search gem在Mongoid中进行简单搜索
