I'm not sure the best way to do this.
I want to have "class Place". "Places" can be listed by either
specific "City", or by a specific "Section" of a city.
list_places_by_city
list_places_by_citysection
Also, I want to have more than one type of place. Is subclasses the
right way to do this? I tried (for "Park" as shown below), but get an
error in the admin that says "'Place' object has no attribute
'has_benches'".
This is what I have sketched out as a test but it doesn't work. There
is the above error, and also the city sections aren't locked to the
proper cities. So it allows "West Springfield" to be located in
"Boston":
from django.db import models
# Create your models here.
class City(models.Model):
CITIES = (
('Boston', 'Boston'),
('Worcester', 'Worcester'),
('Springfield', 'Springfield'),
)
city_name = models.CharField(maxlength=40, choices=CITIES)
def __str__(self):
return self.city_name
class Admin:
pass
class Section(models.Model): # This represents a section of the city
# This isn't keeping the sections in the proper city.
#Do I need unique_together?

SECTIONS = (
('West Boston', 'West Boston'),
('South Boston', 'South Boston'),
('West Springfield', 'West Springfield'),
('Central Worcester', 'Central Worcester'),
('South Worcester', 'South Worcester'),
)
city_section = models.CharField(maxlength=5, choices=SECTIONS)
city = models.ForeignKey(City)
def __str__(self):
return self.city_section
class Admin:
pass
class Place(models.Model):
place_name = models.CharField(maxlength=200)
section = models.ForeignKey(Section)
def __str__(self):
return self.place_name
class Admin:
pass
class Park(Place):
has_benches = models.BooleanField() # just a test. I want certain
types of places to have additional fields.
class Admin:
pass
