我有属于类别的 product_details 表。product_details 具有 id、name、price、discount 和 category_id 等字段，而 categories 表具有 id 和 name 等字段。我正在使用 mysql 数据库我正在尝试根据 category_id 对产品详细信息进行分组。要进行分组，我参考 了 https://gist.github.com/f987013b2feec5b28456。但是我收到以下错误

RSolr::Error::Http - 400 Bad Request
Error:     undefined field category_id

我的模型看起来像这样

    class ProductDetail < ActiveRecord::Base
      belongs_to :category

      searchable do
        text :name
        integer :category_id
      end

    end

我的控制器看起来像这样

def index
      @search_res1=ProductDetail.search do

        adjust_solr_params do |params|
          params[:group] = true
          params[:"group.field"] = "category_id"
          params[:"group.format"] = "simple"
        end

      end.execute
      @navurls=@search_res1.results
end

在我的日志文件中，我是这样的

RSolr::Error::Http 在 ProductDetailsController#index 

RSolr::Error::Http - 400 错误请求
错误：未定义字段 category_id

请求数据：“fq=type%3AProductDetail&fq=category_id_i%3A%281%29&start=0&rows=30&group=true&group.field=category_id&group.format=simple&q=%2A%3A%2A”

回溯：/home/toshiba/.rvm/gems/ruby-1.9.2-p290/gems/rsolr-1.0.8/lib/rsolr/client.rb:230:in `adapt_response'
/home/toshiba/.rvm/gems/ruby-1.9.2-p290/gems/rsolr-1.0.8/lib/rsolr/client.rb:167：在“执行”中
/home/toshiba/.rvm/gems/ruby-1.9.2-p290/gems/rsolr-1.0.8/lib/rsolr/client.rb:161:in `send_and_receive'

请帮我。谢谢你。

这里有两件事：

1. 太阳黑子中的分组仅支持string字段。因此，将您的searchable块更改为以下内容：

class ProductDetail < ActiveRecord::Base
  belongs_to :category

  searchable do
    text :name
    string :category_id_str do
      category_id.to_s
    end
  end
end

2.更改组参数以反映属性名称更改：

def index
  @search_res1=ProductDetail.search do
    adjust_solr_params do |params|
      params[:group] = true
      params[:"group.field"] = "category_id_str_s"
      params[:"group.format"] = "simple"
    end
  end.execute
  @navurls=@search_res1.results
end

我在这里假设太阳黑子在_s索引它时将额外添加到属性中。

也许在 /usr/share/solr/conf 的 schema.xml 中缺少整数类型？

这是我的例子：

<schema name="sunspot" version="1.0">
  <types>
    <!-- field type definitions. The "name" attribute is
       just a label to be used by field definitions.  The "class"
       attribute and any other attributes determine the real
       behavior of the fieldType.
         Class names starting with "solr" refer to java classes in the
       org.apache.solr.analysis package.
    -->
    <!-- *** This fieldType is used by Sunspot! *** -->
    <fieldType name="string" class="solr.StrField" omitNorms="true"/>
    <!-- *** This fieldType is used by Sunspot! *** -->
    <fieldType name="tdouble" class="solr.TrieDoubleField" omitNorms="true"/>
