我有这些模型:
class Entity(models.Model):
name=models.CharField(max_length=100)
class Theme(models.Model):
name=models.CharField(max_length=100)
entity=models.OneToOneField(Entity)
class Company(models.Model):
name=models.CharField(max_length=100)
theme=models.OneToOneField(Theme,null=True,blank=True)
我想在管理员中theme
添加时过滤字段Company
,如下所示:
class CompanyAdmin(admin.ModelAdmin):
def queryset(self, request):
qs = super(CompanyAdmin, self).queryset(request)
qs.theme.queryset = Theme.objects.filter(name__iexact='company')
return qs
admin.site.register(Company, CompanyAdmin)
我尝试了很多东西,但没有任何效果!我怎样才能做到这一点?
