fuzzy search with active record query interface

问题

I have a fuzzy search in my rails app, which sql what I want is this:

select * from `user` where name like '%abc%'

I've tried to do it like this:

name = 'abc'
User.where("name like '%?%'", name)

It failed, in console it logged:

select * from `user` where name like '%'abc'%'

Finally I tried this

name = 'abc'
User.where("name like ?", '%' + name + '%')

It worked.

But I think it doesn't like rails way, is there any better way to do that?

回答1:

User.where("name REGEXP ?", 'regex_str')

and regex_str should be MySQL regex string

Try this..
