Ruby on Rails 7 Destroy Not Showing Alert

When the user clicks on delete, alert not show and go to this path course_path, but don’t delete the course.

Controller

def destroy 
authorize @course
@course.destroy 
respond_to do |format| 
format.html { redirect_to courses_url, notice: "Course was successfully destroyed." } 
format.json { head :no_content }
end
end

The view:

= link_to 'Destroy', course, method: :delete, data: { confirm: 'Are you sure?' }, class: 'btn btn-sm btn-danger

Solution:

– Rails 7 default use Turbo by default, which changes how form submissions and link interactions work.
So need to change in view

= link_to ‘Destroy’, course, data: {turbo_method: :delete, turbo_confirm: ‘Are you sure?’ }, class: ‘btn btn-sm btn-danger’
