django笔记之fixtures

###为何用它

Providing initial data for models

###Where Django finds fixture files

By default, Django looks in the fixtures directory inside each app for fixtures. You can set the FIXTURE_DIRS setting to a list of additional directories where Django should look.

###相关指令

python manage.py loaddata APPNAME
python manage.py dumpdata APPNAME

###导出数据参考这里

python manage.py dumpdata APPNAME
The output of dumpdata can be used as input for loaddata.
Outputs to standard output all data in the database associated with the named application(s).
By default dumpdata will output all the serialized data to standard output.

###导入数据参考这里
