get_direction_descr does something like this:
def get_direction_descr(nod_id1, nod_id2):
cursor = connection.cursor()
cursor.execute("SELECT
GetDirectionDescr("+str(nod_id1)+","+str(nod_id2)+") from sys.dual")
result = cursor.fetchall()
return result[0][0]
and get_vrd_code something similar. I shouldn't save what is being to
returned to the db compared to get_vrd_id and get_direction_db. The
returns of the last two need to be calculated according to a user's
choices(the args) and saved to fields of my model while not being
displayed on the template. I don't know if I could do it somehow
different. For get_vrd_code and get_direction_descr that have the same
args with the previous mentioned, I just want the returns to be
displayed on the template and since the args are passed dynamically I
thought that I can maybe use the same way to get the returns since the
args are available to that point in save(). But now even if I don't
know how I can sense that I should use ajax for that.
