code

class IDC(models.Model):
      uuid = UUIDField(auto=True, primary_key=True)
      name = models.CharField(max_length=64,verbose_name=u'机房名称')

class Server(models.Model):
      idc = models.ForeignKey(IDC, blank=True, null=True, verbose_name=u'机房', on_delete=models.SET_NULL)

class ServerAdmin(admin.ModelAdmin):
      model = models.Server
      exclude = ('memo',)
Solution

  • While you do not set default value for idc field in Server model, this will not be shown in the admin when you create a new object. It will only be shown if you edit already existing object. In order to have default value for this field in the admin, set default value for your idc field in the Server model.
