How to get value from checkbox in rails

Question

I am using simple_form in rails, and I have this as checkbox:

<%= f.input :delivery_days, as: :check_boxes,
    collection: [
      'Sunday',
      'Monday',
      'Tuesday',
      'Wednesday',
      'Thursday',
      'Friday',
      'Satusday',
      'All'],
      wrapper: :vertical_radio_and_checkboxes 
%>

I am not able to get the values of selected checkboxes in my controller.

I am using the following code to get it:

def user_basic_params
    logger.info "from user_basic_params"
    params.require(:profile).permit(:delivery_days[])
end

I have other form fields but they are getting handled correctly and I am able to get their values.

Console output is :

The problem is in the permit(:delivery_days[]) part of your code. Rails expects the brackets to contain 1 or 2 parameters, but you are passing none, thus raising an error. I am not sure why the brackets are there, try removing them and I believe your code should work.

In that case, you are missing the => part that makes it into a hash. `:delivery_days[]` is an attempt to access :delivery_days as an array without giving an offset, while `:delivery_days => []` defines it as a hash with an empty array. – tbrisker Jun 02 '15 at 20:12

Replace this

params.require(:profile).permit(:delivery_days[])

with

params.require(:profile).permit(:delivery_days)
