(1062,"重复输入'0'用于键'PRIMARY'")

Question

我收到了这个错误(1062, "Duplicate entry '0' for key 'PRIMARY'").这是在我将我的Django应用程序从sqlite3迁移到MySQL之后发生的.这是关注的表:

mysql> describe meddy1_specialization;
+-------+-------------+------+-----+---------+----------------+
| Field | Type        | Null | Key | Default | Extra          |
+-------+-------------+------+-----+---------+----------------+
| id    | int(11)     | NO   | PRI | NULL    | auto_increment |
| name  | varchar(30) | NO   |     | NULL    |                |
+-------+-------------+------+-----+---------+----------------+
2 rows in set (0.01 sec)

这是模型:

class Specialization(models.Model):
    name = models.CharField(max_length=30)

    def __unicode__(self):
        return self.name

这是表中的数据:

mysql> select * from meddy1_specialization;
+----+--------------------+
| id | name               |
+----+--------------------+
|  1 | Dentist            |
|  2 | Dermatologist      |
|  3 | Primary Care       |
|  4 | Ophthalmologist    |
|  5 | Pediatrician       |
|  6 | Orthopedist        |
|  7 | Ear, Nose & Throat |
|  8 | Gynecologist       |
|  9 | test               |
| 13 | test               |
| 14 | test1              |
+----+--------------------+
11 rows in set (0.00 sec)

Answer 1

你能检查一下你的mysql数据库的增量数是多少吗？mysql 似乎正在尝试插入具有相同 id 的行。
