根据使用Admin和多个数据库的1.4 documentation，您只需要在ModelAdmin子类中实现5个方法。我以推荐的方式覆盖了所有5个。浏览数据库没有问题。
但是，尝试保存现有记录并且我得到一个错误，声称数据库中不存在该表 - 项目的默认数据库，而不是我在方法实现。事实上，save_model()在抛出错误之前不会被调用，所以在它到达那里之前的某个地方，某个地方没有成功获得正确数据库的“使用”。
任何人都知道缺少什么？这是我的ModelAdmin课程：
class TransactionAdmin(admin.ModelAdmin):
using = "salesdb"
def save_model(self, request, obj, form, change):
# Tell Django to save objects to the 'other' database.
obj.save(using=self.using)
def delete_model(self, request, obj):
# Tell Django to delete objects from the 'other' database
obj.delete(using=self.using)
def queryset(self, request):
# Tell Django to look for objects on the 'other' database.
return super(TransactionAdmin, self).queryset(request).using(self.using)
def formfield_for_foreignkey(self, db_field, request=None, **kwargs):
# Tell Django to populate ForeignKey widgets using a query
# on the 'other' database.
return super(TransactionAdmin, self).formfield_for_foreignkey(db_field, request=request, using=self.using, **kwargs)
def formfield_for_manytomany(self, db_field, request=None, **kwargs):
# Tell Django to populate ManyToMany widgets using a query
# on the 'other' database.
return super(TransactionAdmin, self).formfield_for_manytomany(db_field, request=request, using=self.using, **kwargs)
我得到的错误是：
(1146, "Table 'django_dev._Transactions' doesn't exist")
django_dev是默认数据库，而不是sales数据库。
