django.db.utils.OperationalError:没有这样的表:bookmarks_mytag

标签: python django sqlite

我正在尝试django.db.utils.OperationalError: no such table: bookmarks_mytag安装django项目。 回购是http://bitbucket.org/codyc54321/bookwormbud.git

我们做了

touch db.sqlite3
python manage.py migrate

它爆炸了:

该项目立即安装在另一台笔记本电脑上,但我不记得它是如何设置的。 sqlite数据库已被删除并重新为空,因为据说在SO上做了。任何帮助表示感谢,谢谢

2 个答案:

答案 0 :(得分:0)

您是否尝试在python manage.py makemigrations之前运行migrate

答案 1 :(得分:0)

您正在手动创建空db文件。您不需要手动创建该文件。删除你的&#34; db.sqlite3&#34;文件,然后运行命令,

python manage.py makemigrations

如果上面的命令显示&#34;未检测到任何更改&#34;,则运行此命令,

python manage.py makemigrations app_name

其中,app_name将是models.py文件所在的目录名,

使用上面的命令,您已成功创建了迁移文件, 现在,简单地跑,

python manage.py migrate

我希望这个帮助
