Django的自動創建模型

Question

我的模型：

class Urunler(AnaModel): 
    adi = models.CharField(max_length=128, verbose_name="Ürün Adı") 
    aciklama = models.TextField(verbose_name="Açıklama") 
    kategori = models.ForeignKey(Kategoriler, verbose_name="Kategori", related_name="urunler", null=True) 
    agirlik = models.DecimalField(max_digits=6, decimal_places=2, verbose_name="Ağırlık", default=Decimal(1)) 
    birim = models.CharField(max_length=2, choices=BIRIMLER, default="kg") 

class Stok(AnaModel): 
    adi = models.ForeignKey(Urunler, related_name="stok", verbose_name="Ürün Adı") 
    marka = models.CharField(max_length=256, verbose_name="Marka/Firma") 
    stok_giris = models.DateTimeField(verbose_name="Stok Giriş Tarihi") 
    uretim_tarihi = models.DateField(verbose_name="Üretim Tarihi", blank=True, null=True) 
    sk_tarihi = models.DateField(verbose_name="Son Kullanma Tarihi", blank=True, null=True) 
    irsaliye_no = models.PositiveIntegerField(max_length=32, verbose_name="İrsaliye No", blank=True) 
    fatura_no = models.PositiveIntegerField(max_length=32, verbose_name="Fatura No", blank=True) 
    adet = models.PositiveIntegerField(default=Decimal(1)) 
    aciklama = models.TextField(verbose_name="Açıklama", null=True) 

class StokCikis(AnaModel): 
    adi = models.ForeignKey(Urunler, related_name="stok_cikis", verbose_name="Ürün Adı") 
    stok_cikis = models.DateTimeField(verbose_name="Stok Çıkış", blank=True, null=True, auto_now=True) 
    teslim_alan = models.CharField(verbose_name="Teslim Alan", max_length=128, null=True, blank=True) 
    aciklama = models.TextField(verbose_name="Açıklama", null=True, blank=True) 
    adet = models.PositiveIntegerField(default=Decimal(0) 

當 「Urunler」 模型創建產品。可以自動生成「庫存」和「StockCikis」模型嗎？我想用默認值自動創建它。

你可以使用模型的保存方法：

class Urunler(AnaModel): 
    ... 
    def save(self, *args, **kwargs): 
     super(Urunler, self).save(*args, **kwargs) 
     newStok = Stok() 
     ... 
     newStok.save() 
     newStokCikis = StokCikis() 
     ... 
     newStokCikis.save()
