I think I understand what you want now, this is a clean up of what you did
but I dont think is what you want
def create
@appointment = Appointment.where("date = ? && timeslot = ?",
date,timeslot).first_or_initialize
respond_to do |format|
if @appointment.new_record? # this means you did NOT found an
Appointment for the given date and timeslot
format.html { redirect_to new_appointment_path, notice:
'Appointment was successfully created.' }
format.json { render :show, status: :created, location:
@appointment }
else # this means you did found an Appointment for the given date and
timeslot
format.html { redirect_to root_path, notice: 'That appointment
is not available, please choose again' } # this redirect works with no
notice
format.js { render json: @appointment.errors, status:
:unprocessable_entity }
end
end
end
now keep in mind that you are doing it wrong, 'create action' it for
creating, what you need is
a contitional link that leads to either new or index action and leave
create alone doing only what
it should. So can you explain your goal as a user story, so that I can
guide you to do it properly ?
