Rails radio_button check conditionally in loop

I have radiobuttons creaated in loop.

- @annual_packages.each do |plan|
    = f.radio_button('plan_id', plan.id)
    = plan.title

How can I make condition to check radio if plan.id == @plan.id

Doesn't work:

 = f.radio_button('plan_id', plan.id, checked: (plan.id == @plan.id))

Loop code: 

= form_for @organization, url: subscription_create_path, remote: true, method: :post do |f|
   - unless @annual_packages.blank?
     - @annual_packages.each do |plan|
       = f.radio_button('plan_id', plan.id)
       = plan.title

If you are using simple_form or form_for, and f is your form object then you can simply do:

for form_for: radio_button(object_name, method, tag_value, options = {}) refer

in your case:

 - @annual_packages.each do |plan|
    radio_button("your object name", "plan_id", plan.id, options = {})

If the current value of method(object.plan_id) is tag_value(plan) the radio button will be checked.

for simple_form:

= f.input :plan_id, as: :radio_buttons, collection: @annual_packages

Can you post your form_for code?

Cause if your column plan_id have any value, it should be checked automatically if it matches the tag_value`.

If the current value of method is tag_value the radio button will be checked.
