Yes, you are right.
Removing core=True solved the issue.
However I think an error message from admin web interface is needed
when things go wrong.
Or should the default model validator to point to the error?
As during all my experiments in the terminal where the server was
running I always got:
-
class PizzaTopping(models.Model):
pizza = models.ForeignKey(Pizza,
help_text = 'Toppings to go on Pizza:
num in admin is how many will show up in Pizza',
edit_inline = models.TABULAR,
num_in_admin = 3,
Let me add that it isn't a Python version problem, it's the same with
python 2.4 and 2.5.

Thanks. I forgot about that example!

This is what I do:
1. I create a new project with the model file made by a copy-and-paste
of the code I posted above. I add my new app to configuration files.
2. I create a new db and I create tables it with syncdb
3. manage.py runserver and I
I use this code in quite a few of my programs and never have issues. I
don't know why you are having this problem and it is not throwing any
errors. Are you using the Web interface at all? If so when saving are
there any errors. If the objects aren;t saving to the db generally

I deleted the db and resync done, but still got the same problem.
I add a few toppings and it works.
I add one pizza with some toppings and their quantities: admin says
everything is right, but really it isn't: pizza_pizzatopping is an
empty table, while pizza_pizza got the right entry. The pizza
Because of the dependants you might need to either manually add the
tables to the db or if you don't have any values in that table delete
all the rows in pizza and run syncdb again. Sometimes when working
within the same class the syncdb doesn't change the database all the
way (and rightly so). Gi
Thanks to you all, I took something from all the replies and I wrote
this modifying Michael code:
class Topping(models.Model):
name = models.CharField(maxlength=255, unique=True)
def __str__(self):
return self.name
class Admin:
pass
class Pizza(models.Model):
n
Nis;
Thanks for catching that I left the manytomany field there. There is
no need for that.
revised code:
class Topping(models.Model):
# ...
class Pizza(models.Model):
# ...
class PizzaToppings(model.Model):
pizza = models.ForeignKey(Pizza, help_text='Toppings to go on
Pizza: num in

You could need an extra class for this but it should work:
class Topping(models.Model):
# ...
class Pizza(models.Model):
# ...
toppings = models.ManyToManyField(Topping)
class PizzaToppings(model.Model):
pizza = models.ForeignKey(Pizza, help_text='Toppings to go on
Pizza: num in
Hi,
I searched about this subject and found only a few very old posts, so
maybe there is a better solution now.
As you may guess the model I'd like to code is similar to the Pizza -
Toppings you know from the "Creating Models" documentation:
class Topping(models.Model):

class Pizza(mo
