Rails check_box_tag checked according boolean value

In my db, I've a boolean field: is_in_city.

In view, I try to set check_box_tag as:

= check_box_tag c.is_in_city

But it is never checked even if the db value is true. What is wrong?

I need to do such chekbox, which is no/is checked according to db boolean field value stored in the database. How can I do this? Also how can I set one more my property to checkbox?

The proper use of the check_box_tag method is like this:

= check_box_tag :name, value, checked

Where value can be anything, checked (should be) a boolean.

In your case:

= check_box_tag :is_in_city, 1, c.is_in_city
