Hi all,
i'm trying to do a simple task with Django but evidently it is not so
simple...
I have my model:
class Mymodel(models.Model):
random_string = models.CharField(max_length=200)
def produce_string(self):
a = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "L", "M",
"N", "O", "P", "Q", "R", "S", "T", "U", "V", "Z", "0",
"1", "2", "3", "4", "5", "6", "7", "8", "9"]
num = ""
random.shuffle(a)
for x in a[:8]:
num = num + x
self.random_string= num
What i'd like to do is having a random string stored into my new
object as soon as i'll create my object. To do that i've inserted this
method into previous code:
def __init__(self,*args, **kwargs):
super(Mymodel, self).__init__(*args, **kwargs)
self.produce_string()
So running django's shell, everything seems to work fine...
from test.testing.modules import Mymodel
m = Mymodel()
m.random_string
> "23467.."
m.save()
>OK
But if i try to get all objects saved into my db (so using
Mymodel.objects.all()) what i get is a different result every time i
run this command.
What i've noticed is that Mymodel.objects.all() run "__init__" method
inside my class, so what i got as results is everytime a different
results set (random_string is not the one stored into db but a random
one produced by produce_string method).
What's wrong with this code? Am i missing something?
Many thanks in advance
