Question

我有一个（mysql-）表，其中包含两列的全文索引 - ＆gt;名字，中间名。

当我使用SQl时

SELECT firstname, middlename, MATCH (firstname, middlename) as score AGAINST ('Peter') FROM database.tbl_names where MATCH (firstname, middlename) AGAINST ('Peter')

我得到3列 - ＆gt;名字，中间名和分数。

但是当我尝试使用红宝石时

TblName.find(:all, :select => "firstname, middlename, match(firstname, middlename) against ('Peter')as score", :order => 'score desc', :conditions => ['match(firstname, middlename) against (?)', 'Peter'], :limit => 20)

我只得到一个包含两个＆＃34;列的数组＆＃34;但没有＆＃34;匹配列＆＃34;

<TblName firstname: "Peter", middlename: "">

我在整个星期天搜索了一个尝试过，并没有找到＆＃34; match-column＆＃34;的解决方案。在阵列中。

有人能帮助我吗？

提前致谢!!!

Answer 1

Rails 4版本：

Model.select("*, MATCH(title) AGAINST ('keyword') AS score").where("MATCH(title) AGAINST('keyword')").reorder("score DESC").first.score

Answer 2

Rails不会在返回的数组中显示“score”属性（因为它未在模型中初始化）。您必须使用属性调用来查找它。

尝试：

TblName.find(:all, :select => "firstname, middlename, match(firstname, middlename) against ('Peter') as score", :order => 'score desc', :conditions => ['match(firstname, middlename) against (?)', 'Peter'], :limit => 20).first.score

看看你是否能以这种方式得分。

您还可以使用以下方法获取该记录的属性列表（包括分数）：

TblName.find(:all, :select => "firstname, middlename, match(firstname, middlename) against ('Peter') as score", :order => 'score desc', :conditions => ['match(firstname, middlename) against (?)', 'Peter'], :limit => 20).first.attributes

如果您想一次查看所有记录的属性，可以这样做：

TblName.find(:all, :select => "firstname, middlename, match(firstname, middlename) against ('Peter') as score", :order => 'score desc', :conditions => ['match(firstname, middlename) against (?)', 'Peter'], :limit => 20).collect!(&:attributes)
