rails check_box_tag设置为默认值 [英] rails check_box_tag set checked with default value

问题描述

我目前有一个看起来像Rails的check_box_tag呼叫

I currently have a rails check_box_tag call that looks like

check_box_tag #{name}

我想添加一个选中的属性，我知道我可以使用

I want to include a checked attribute, which I know I can do with

check_box_tag name, value, checked

但是如果我想将其设置为选中而不显式指定value(我只想使用默认值)怎么办.或类似地，如果我想在不指定checked属性的情况下指定html选项，该怎么办.有办法吗?

But what if I want to set it to checked without explicitly specifying value (I just want to use the default). Or similarly, what if I wanted to specify html options without specifying the checked attribute. Is there a way to do this?

推荐答案

只想更新此内容. check_box_tag的第三个参数是代表检查状态的布尔值.

Just wanted to update this. The third parameter for check_box_tag is a boolean value representing the checked status.

check_box_tag name, value, true
