Ok so i have this form and i want to be able to pass a variable to my index method on my controller when i click on the button.
This is because i want my controller to know if the clear button has been clicked and the only way for me to do tht is to pass a variable to my controller index method.
my controller method
def index
#banker = Banker.where("locked_at is null and approved = true").order('name asc')
ap params
if !params[:get_status].nil?
params[:banker_status] = BankerAssignmentStatus.where("assignment_status =? ",params[:get_status]).pluck(:id)
end
search_banker_assignment params
render template: 'cc_banker_assignments/index'
end
How do i do this using rails

Answer 1

Are you trying to clear the form inputs by requesting index page? You can use link_to instead of button_tag to do that, or just javascript. If you really want to pass a variable to the controller, you can bind your button to a jQuery.ajax() call.
