I'm a true novice programmer, brand new to django, but lovin' it so
far. I was wondering if there was any way to do something a little
tricky via the Admin classes that could help me not write a custom
view.
Basically I'd love to do all my data entry from the Admin interface,
but I need to filter a set of choices on one Admin input interface
based on a choice I make further up the form.
I live in a world with:
2 restaurants (McDonalds and Burger King)
4 menu items, the same type of food at each restaurant (mc_burger,
mc_fries, bk_burger, bk_fries)
Each time I eat at one of those restaurants I want to make a record of
the meal in my database. So I do the data entry through the django
Admin backend. If I select "Burger King" as the restaurant that I eat
my meal at, when it comes time to select the dishes I ate, I really
only want to see bk_fries and bk_burger, cuz I ate at BK and not
mickey D's.
Can this be done just using the Admin class in models.py?
Here's the sample code that I'm working with in model.py:
class Restaurant(models.Model):
def __str__(self):
return self.name
name = models.CharField('Restaurant Name', maxlength=200, blank=True)
class Admin:
fields = (
('Restaurant Name' , {'fields': ('name',)}),
)
pass
class Dishes(models.Model)
def __str__(self):
return self.name
name = models.CharField('Restaurant Name', maxlength=200, blank=True)
class Admin:
fields = (
('Dish Name' , {'fields': ('name',)}),
)
pass
class IndividualMeal(models.Model):
def __str__(self):
return self.name
restaurant_name = models.ForeignKey(Restaurant,
verbose_name="restaurant")
date_of_visit = models.DateTimeField('date of visit')
dishes = models.ManyToManyField(Dish, verbose_name="individual
dishes")
class Admin:
fields = (
('Restaurant Name' , {'fields': ('restaurant_name',)}),
('Date of Visit', {'fields': ('date_of_visit',)}),
('Dishes', {'fields': ('dishes',)}),
)
pass
