Django 转储单个模型的数据? [英] Django dump data for a single model?

问题描述

我可以在 Django 中执行 dumpdata只是一个模型，而不是整个应用程序，如果是这样，如何?

Can I perform a dumpdata in Django on just a single model, rather than the whole app, and if so, how?

对于应用程序，它是:

python manage.py dumpdata myapp

但是，我想要转储某些特定模型，例如myapp.mymodel".原因是，我在同一个应用程序中有一些巨大的、超过 300 万条记录的数据集，我不想丢弃这些数据集.

However, I want some specific model, such as "myapp.mymodel" to be dumped. The reason being, I have some huge, 3 million records plus, datasets in the same app that I would not like dumped.

推荐答案

从 1.1 及更高版本开始，Django dumpdata 管理命令允许您从单个表中转储数据:

As of version 1.1 and greater, the Django dumpdata management command allows you to dump data from individual tables:

./manage.py dumpdata myapp1 myapp2.my_model

您还可以在命令行上分离多个应用程序和模型.这是规范定义:

You can also separate multiple apps and models on the command line. Here's the canonical definition:

django-admin dumpdata [app_label[.ModelName] [app_label[.ModelName] ...]]
