我的应用程序 (Django v 2.2.5) 正在使用 MySQL (MariaDB 10.4.6) 将数据存储在其数据库中，并完成并提交了所有迁移。它创建了超级用户，当我登录时，我可以创建所有相关的对象，但是Product（可以说是最重要的）没有被创建。我已经尝试更改模型，甚至删除BooleanField（唯一与正在存储的模型不同的唯一字段）并应用迁移，但它仍然不起作用。我什至删除了整个数据库并重新开始，希望绕过任何棘手的迁移，但这对我仍然没有任何帮助。这是我的models.py：
class Partner(models.Model):
name = models.CharField(max_length=150, blank=False, help_text="Enter the vendor name", verbose_name="Vendor name", unique=True)
address = models.TextField(help_text="Enter the address of the vendor")
formula = models.ForeignKey(Formula, on_delete = models.CASCADE)
phone = PhoneNumberField(help_text="enter the vendor phone number")
email = models.EmailField(max_length=254, help_text="Enter the vendor email address")
photo = models.ImageField(upload_to="vendors")
def __str__(self):
return self.name
class ProductType(models.Model):
name = models.CharField(max_length=150, blank=False, help_text="Enter the kind of product this is", verbose_name="Product type")
def __str__(self):
return self.name
class Product(models.Model):
name = models.CharField(max_length=150, blank=False, help_text="Enter the name of the product", verbose_name="Product name")
price = models.DecimalField(max_digits=12, decimal_places=5,\
help_text="Enter the price of the product", \
blank = False, default=0.0)
product_type = models.ForeignKey(ProductType, on_delete = models.CASCADE)
vendor = models.ForeignKey(Partner, on_delete = models.CASCADE)
photo = models.ImageField(upload_to="products")
def __str__(self):
return self.vendor.name + ": " + self.name
我正在使用的任何字段或元数据参数是否不受支持？我对自己做错了什么感到迷茫。我试着查看日志，但看不到任何明显的东西可以为我指明正确的方向（我承认我不太擅长数据库）。这是错误日志：
