how to set value of simple form checkbox to String?

Question

i have checkbox in simple form:

= f.input :status, as: :boolean

but i don't want values to be 0 or 1. i want them to be Strings, like eg 'not_done' and 'completed'. how can i achieve that? i ran into some kind of solution on github thread, but i don't really know what is it doing, plus, it always give me "new" as value, doesnt matter if the field is checked or not...

= f.input :status, as: :boolean do
    - f.check_box :status, {}, "new", "confirmed"

The "check_box" method should work: api.rubyonrails.org/classes/ActionView/Helpers/…. You don't need the first "f.input". Just the checkbox. — Ben Lee

Kuba, it should look exactly like it already does: f.check_box :Status, {}, "new", "confirmed". But just that part. Completely get rid of the f.input :status. That is shadowing the checkbox result. — Ben Lee

You can do

<%= f.input :status, as: :boolean,
                     checked_value: 'completed',
                     unchecked_value: 'not_done'
                     %>

This will set the values as completed when checked and not_done when unchecked.

However, if you want to go ahead and display the same, you can do:

<%= f.input :status, as: :boolean,
                     checked_value: 'completed',
                     unchecked_value: 'not_done',
                     input_html: {
                       name: 'status_checkbox', # not a must, will help for identification and testing
                       checked: params[:status] == 'completed' ? 'Completed' : 'Not Done'
                     } %>

If you want to go with check_box then its possible:

<%= f.input :status, :as => :check_boxes, collection: [['Completed', 'completed']]  %>

But you should not expect two values from a check_box. It will carry only one value. the reverse will be considered if the check box is not checked.
