编辑的Django模型保存它

Question

我有下面的代码后：

models.py

class TelefoneIP(models.Model): 
     mac = models.CharField(max_length=12, help_text="Este campo deve ter 12 digitos") 
     modelo = models.ForeignKey(ModeloTelefoneIP) 
     cliente_atual = models.ForeignKey(Cliente) 
     fornecedor = models.ForeignKey(Fornecedor) 
     datacompra = models.DateField(verbose_name="Data de compra", null=True, blank=True) 
     nfcompra = models.IntegerField(verbose_name="Nota fiscal de compra") 

class MovimetoTelefoneIP(models.Model): 
     equipamento = models.ForeignKey(TelefoneIP) 
     cliente = models.ForeignKey(Cliente) 
     nfvenda = models.IntegerField(verbose_name="Nota fiscal de saída", null=True, blank=True) 
     datavenda = models.DateField(verbose_name="Data de saída", null=True, blank=True) 

admin.py：

class TelefoneIPInline(admin.StackedInline): 
     model = MovimetoTelefoneIP 
     extra = 1 
     list_filter = ['nome'] 

class TelefoneIPAdmin(admin.ModelAdmin): 
     list_display = ('mac', 'modelo', 'fornecedor',) 
     list_filter = ['cliente_atual__nome'] 
     search_fields = ['mac'] 
     inlines = [TelefoneIPInline] 

的问题是，当我编辑的内嵌，我可以在保存时将cliente_atual（在TelefoneIP上）的值设置为客户端（在MovimentoTelefoneIP上）？

谢谢。

PS：我在MovimentoTelefoneIP里输入了这段代码，但是没有工作。 更新了字段cliente_atual，但内联数据没有保存。 我也试过Hassek的代码并没有什么..

def save(self, *args, **kwargs): 
      MovimetoTelefoneIP.save() 
      equipamento = self.equipamento 
      equipamento.cliente_atual = self.cliente 
      equipamento.save()

是的，你必须覆盖从形式保存，并添加形式向管理员：

class TelefoneIpForm(forms.ModelForm): 
    class Meta: 
     model = TelefoneIp 

    def save(self, commit=True): 
     instance = super(TelefoneIpForm, self).save(commit=commit)   

     equipamento = instance.equipamento 
     equipamento.cliente = instance.cliente_atual 
     equipamento.save() 

class TelefoneIPAdmin(admin.ModelAdmin): 
    list_display = ('mac', 'modelo', 'fornecedor',) 
    list_filter = ['cliente_atual__nome'] 
    search_fields = ['mac'] 
    inlines = [TelefoneIPInline] 
    form = TelefoneIpForm 

我还没有测试的代码所以如果信息无法像代码中显示的那样访问，只需检查调试对象pdb

我发现了另一种逻辑方法来解决我的问题。但我仍然有疑问：Access data from a related class in Django
