    projectDescription = models.CharField(max_length=50, null=True, blank=True, default=None)
    projectHost = models.CharField(max_length=50, null=True, blank=True, default=None)
    status_choices = (
        (1, "研发中"),
        (2, "研发完毕"),
        (3, "测试中"),
        (4, "测试完毕"),
    )#下拉框选项值
    projectStatus = models.SmallIntegerField(choices=status_choices)

    projectOwner = models.CharField(max_length=50, null=True, blank=True, default=None)

    def __str__(self):
        """定义每个数据对象的显示信息"""
        return self.projectName

    class Meta:
        db_table = "projectInfo"
