Question

我只想要下面的一个模型实例。如何在代码中强制执行此操作？

class Employer(models.Model):
    name=models.CharField(max_length=50, verbose_name = "Employer's Name")
    pin =models.CharField(max_length=50, verbose_name ="Employer's PIN")

    def __unicode__(self):
        return self.name

试试这个：

class Employer(models.Model):
    name = models.CharField(max_length=50, verbose_name="Employer's Name")
    pin = models.CharField(max_length=50, verbose_name="Employer's PIN")

    def __unicode__(self):
        return self.name

    class Meta:
        unique_together = ('name', 'pin')

来自Django Model Meta options。

只有一个django模型的实例
