问候,我有这两个模型:
from django.db import models
class Office(models.Model):
name = models.CharField(max_length=30)
person = models.CharField(max_length=30)
phone = models.CharField(max_length=20)
fax = models.CharField(max_length=20)
address = models.CharField(max_length=100)
def __unicode__(self):
return self.name
class Province(models.Model):
numberPlate = models.IntegerField(primary_key=True)
name = models.CharField(max_length=20)
content = models.TextField()
office = models.ForeignKey(Office)
def __unicode__(self):
return self.name
我希望能够为省份选择几个办事处,这是一对多的模型。这是我的admin.py:
from harita.haritaapp.models import Province, Office
from django.contrib import admin
class ProvinceCreator(admin.ModelAdmin):
list_display = ['name', 'numberPlate','content','office']
class OfficeCreator(admin.ModelAdmin):
list_display = ['name','person','phone','fax','address']
admin.site.register(Province, ProvinceCreator)
admin.site.register(Office, OfficeCreator)
现在,我可以在管理面板上为每个省选择一个Office,同时创建一个新的省但我希望能够选择多个。我怎样才能做到这一点?
此致

我不确定我是否误解了你,但你的模特目前说“办公室可以与许多省份联系,但每个省可能只有一个办公室”。这与你想要的相矛盾。请改用ManyToMany字段:
class Province(models.Model):
numberPlate = models.IntegerField(primary_key=True)
name = models.CharField(max_length=20)
content = models.TextField()
office = models.ManyToManyField(Office)
def __unicode__(self):
return self.name
