o.k.
Now it is like that:
def update
if params[:booking_ids]
params[:booking_ids].each do
Booking.update(params[:booking].keys, params[:booking].values).reject
{ |p| p.errors.empty? }
end
end
respond_to do |format|
format.js{
@project = Project.find(params[:id])
@main_hours = main_hours_sum(@project.id)
}
end
end
def main_hours_sum(id)
hours ||= Booking.where(project_id: id).sum("hour")
end
update.js.erb
alert('<%= @main_hours %>')
The alert pops up and shows the correct amount of hours..
Thanks so far.....but I dont have an idea how to update/reset the
@main_hours on the edit page where it is shown. As I dont leave this page,
no request - no update.
May be my understanding of this process is not enough yet.
Greetings
