mysql - (1062, "Duplicate entry ' 0' for key ' 主'")

Question

我收到此错误 (1062，“键‘PRIMARY’的重复条目‘0’”)。这发生在我将我的 Django 应用程序从 sqlite3 迁移到 MySQL 之后。这是相关的表格:

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

你能在你的 mysql 数据库中检查增量数字是多少吗？看来 mysql 正在尝试插入具有相同 id 的行。
