rails check_boxの使い方

More than 3 years have passed since last update.

<%= f.check_box 'カラム名',{},checked_value = "true",unchecked_value = "false" %>

checked_value = "true"

チェックした時にtrueが送られる。

 uncheked_value = "false"

チェックした時にfalseが送られる。

""をつけなければエラーは発生しないが、全部trueになってしまう。

こっちでもok
<%= f.check_box 'カラム名',{}, "true", "false" %>

trueにしたユーザーを取り出すには

Hoge.where({ カラム名: 1 })で取り出すことができる。
