模型

Question

大家好我对表格有疑问。我有两个模型，其中一个模型在不同的模型上有3个相关的ForeignKeys。在下面的例子中将显示代码。问题是第一个表单是提交确定，并插入到数据库工作。但下一个表格不会提交。不知道我做错了什么。

模型

class OutgoingInvoice(models.Model):
    id = models.AutoField(primary_key=True)
    invoice_number = models.IntegerField()
    date = models.DateField()
    time = models.TimeField()
    place = models.CharField(max_length=255)
    status = models.CharField(max_length=255)
    due_date = models.DateField()
    total_invoice_amount = models.DecimalField(decimal_places=5, max_digits=255)
    vat_amount = models.DecimalField(decimal_places=5, max_digits=255)
    invoice_amount = models.DecimalField(decimal_places=5, max_digits=255)
    discount = models.DecimalField(decimal_places=5, max_digits=255)
    user_id = models.ForeignKey('IzibiziUser')
    organization_id = models.ForeignKey('IzibiziOrganization')
    customer_id = models.ForeignKey('OrganizationInfo')

    def __str__(self):
        return str(self.id)

如果你能看到我做错了什么。提交表单时，我在表单上没有任何错误。

Answer 1

在对数据执行任何操作之前，您需要检查两个表单是否有效，并且只有在两个表单都有效时才重定向。这样：

    if new_customer.is_valid():
        a = new_customer.save()

        if new_inovce.is_valid():
            ...
    return HttpResponseRedirect('/novi_izlazni_racuni/')

应该是这样的：

    valid = new_customer.is_valid()
    valid = new_inovce.is_valid() and valid
    if valid:
        a = new_customer.save()
        ...
        return HttpResponseRedirect('/novi_izlazni_racuni/')

这会强制验证两种表格
