Sql 充当标记：查找具有名称的标记，如，按标记计数排序？

您好，我正在使用rails插件

作为

上的标记，我正在尝试查找名称匹配和部分匹配给定查询的前5个最常用的标记

当我执行

User.skill\u counts.order（'count DESC'）。limit（5）。where（'name LIKE？'，params[：query]）

这将返回以下错误：

ActiveRecord::StatementInvalid: SQLite3::SQLException: ambiguous column name: name: SELECT     tags.*, COUNT(*) AS count FROM       "tags" INNER JOIN users ON users.id = taggings.taggable_id LEFT OUTER JOIN taggings ON tags.id = taggings.tag_id AND taggings.context = 'skills' WHERE     (taggings.taggable_type = 'User') AND (taggings.taggable_id IN(SELECT     users.id FROM       "users")) AND (name LIKE 'asd') GROUP BY  tags.id, tags.name HAVING    COUNT(*) > 0 ORDER BY  count DESC LIMIT 5

但是当我做

User.skill\u时，first.name很重要

这是回报

"alliteration"

我非常感谢您在这件事上的任何帮助。
旅游查询应该是这样的

SELECT  tags.*, COUNT(*) AS count FROM  "tags" 
         INNER JOIN users ON users.id = taggings.taggable_id 
         LEFT OUTER JOIN taggings ON tags.id = taggings.tag_id AND taggings.context = 'skills'
         WHERE  (taggings.taggable_type = 'User') AND 
                (taggings.taggable_id IN(SELECT users.id FROM "users")) AND 
               (tags.name LIKE 'asd') 
         GROUP BY  tags.id, tags.name HAVING COUNT(*) > 0 
         ORDER BY  count DESC 
         LIMIT 5

为此，请尝试以下内容

User.skill_counts.order('count DESC').limit(5).where('tags.name LIKE ?', params[:query]) 

巡更查询应该如下所示

SELECT  tags.*, COUNT(*) AS count FROM  "tags" 
         INNER JOIN users ON users.id = taggings.taggable_id 
         LEFT OUTER JOIN taggings ON tags.id = taggings.tag_id AND taggings.context = 'skills'
         WHERE  (taggings.taggable_type = 'User') AND 
                (taggings.taggable_id IN(SELECT users.id FROM "users")) AND 
               (tags.name LIKE 'asd') 
         GROUP BY  tags.id, tags.name HAVING COUNT(*) > 0 
         ORDER BY  count DESC 
         LIMIT 5

为此，请尝试以下内容

User.skill_counts.order('count DESC').limit(5).where('tags.name LIKE ?', params[:query])
