class QdProjectAssist(models.Model):
    project_id = models.ForeignKey('QdProject', on_delete=models.CASCADE)
    assist_id = models.ForeignKey('QdAssist', on_delete=models.CASCADE)
    sort = models.PositiveIntegerField('排序', blank=True, null=True)
    add_time = models.PositiveIntegerField()
    uptime = models.DateTimeField( auto_now=True)

    class Meta:
        managed = False
        db_table = 'project_assist'
        unique_together = ('project_id', 'assist_id')

我从mysql导出带有两个主键的表。

在使用过程中报告错误:

django.db.utils.InternalError: (1054, "Unknown column 'qd_project_assist.id' in 'field list'")

答案 0 :(得分:0)

如果您处于开发环境中,请尝试删除所有表并再次运行df.groupBy("location").count().show()
