django admin错误 - '字段列表'中的未知列'django_content_type.name'

Question

我的django项目有一个工作的管理页面,但突然间我开始接收: "Unknown column 'django_content_type.name' in 'field list'"每当我尝试访问管理页面时.我仍然可以访问管理员的某些部分,而不是主页面.

我对django和python很新,所以我不知道在哪里看.

这是完整的错误:

第63行发生html错误:

Answer 1

我刚才有同样的问题,它与不同版本的django有关.我使用pip install -U Django将我项目中工作的所有机器更新到django 1.8,之后一切正常.

Answer 2

MySQL中的修复程序是删除表django_content_type;

来自karthikr和moonchel的笔记引领我解决问题.1054在将Django 1.8安装到一个virtualenv中以尝试它之后发生了未知的列错误,然后尝试在不同的virtualenv中使用预先存在的Django 1.6.MySQL搞砸了.

Django 1.7/1.8 syncdb修改了django_content_type表,从中删除了'name'列.

+-----------+--------------+------+-----+---------+----------------+
| Field     | Type         | Null | Key | Default | Extra          |
+-----------+--------------+------+-----+---------+----------------+
| id        | int(11)      | NO   | PRI | NULL    | auto_increment |
| app_label | varchar(100) | NO   | MUL | NULL    |                |
| model     | varchar(100) | NO   |     | NULL    |                |
+-----------+--------------+------+-----+---------+----------------+

Django 1.6 syncdb creates the table with the 'name' column:
+-----------+--------------+------+-----+---------+----------------+
| Field     | Type         | Null | Key | Default | Extra          |
+-----------+--------------+------+-----+---------+----------------+
| id        | int(11)      | NO   | PRI | NULL    | auto_increment |
| name      | varchar(100) | NO   |     | NULL    |                |
| app_label | varchar(100) | NO   | MUL | NULL    |                |
| model     | varchar(100) | NO   |     | NULL    |                |
+-----------+--------------+------+-----+---------+----------------+

因此,删除表并让syncdb根据Django版本的需要重新创建它.如果担心丢弃它,请采取转储:mysqldump -u <mysqladminname> -p <databasename> django_content_type > /tmp/django_content_type.dmp
