如何填写数据表？

Question

请帮助解决问题。

python3.4、django1.6。 我正在尝试将数据从文件 initial_data.json 放入数据库

在命令之后

python manage.py syncdb --all

创建了表，但文件 initial_data.json 中的数据不适合表。这是控制台输出：

(ds_d16)kalinins@kalinins-Lenovo-Z580 ~/.virtualenvs/ds_d16/django_projects/drummersaransk_new $ python manage.py syncdb --all

You just installed Django's auth system, which means you don't have any superusers defined.

Answer 1

根据我的经验，使用初始 json 数据是一件麻烦事。使用 sql 插入创建初始值要容易得多。从您的数据库中制作一个初始值的 sql 转储，并将它们转换为每个模型单独的 .sql 文件。将它们放在正确应用的文件夹中。

所以它可能是这样的：
- foo (your app) - sql (the sql folder *with* __init__.py) - bar.sql (your Bar model insert sql's)

试试这个。
