python - django 重置内容类型不匹配

Question

已删除我的数据库。

已运行 SyncDb。

尝试从转储 ..-python manage.py loaddata dump.json 加载。

获取-“<1062 键的重复条目 ''..”

已运行“python manage.py reset contenttypes”

但是得到——

 Error: Error: contenttypes couldn't be reset. Possible reasons:
  * The database isn't running or isn't configured correctly.
  * At least one of the database tables doesn't exist.
  * The SQL was invalid.
Hint: Look at the output of 'django-admin.py sqlreset contenttypes'. That's the SQL this command wasn't able to run.
The full error: (1217, 'Cannot delete or update a parent row: a foreign key constraint fails')

尝试运行：

from django.core 导入管理

management.call_command("flush", verbosity=, interactive=False)

management.call_command("完全重置", "contenttypes", verbosity=, interactive=False)

management.call_command("loaddata", "full_test_data.json", verbosity=)

但是get-语法错误。

有python 2.7。和 Django 1.4

有任何想法吗？

Answer 1

尝试设置foreign_key_checksfalse，

DATABASES = {
    'default': {
        # ...         
        'OPTIONS': {
            "init_command": "SET foreign_key_checks = 0;",
        },
    }
}

但是您绝对应该尝试使用带有--natural选项的 dumpdata 命令，以确保您的设备中没有硬编码的内容类型。
