simple_form: specify id of text field

问题

I've got the simple simple_form below. I'm trying to make the ID of the input field be 'my-id', but the solution below doesn't work (the id is 'comment_body'). How can I specify the id for that input field?

= simple_form_for(@comment) do |f|
    = f.input :body, as: :string, html: {id: "my-id"}
    = f.button :submit

I've also tried

    = f.input :body, as: :string, id: "my-id"

to no avail.

回答1:

:input_html works, not :html.

 = f.input :body, as: :string, input_html: {id: "my-id"}

回答2:

The way to add an ID to a simpleform input field has changed since this question was first answered.

The latest syntax (version 3.2.0) would be what the op tried:

 = f.input :body, as: :string, id: "my-id"

I thought I'd add an update to this question as it comes near to the top of Google when searching for 'simpleform id'.
