Django转储数据为单个模型？ [英] Django dump data for a single model?

问题描述

可以在中执行 dumpdata Django 只是一个单一的模型，而不是整个应用程序，如果是的话，怎么样？

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

对于一个应用程序，它将是：

For an app it would be:

python manage.py dumpdata myapp

但是，我想要一些特定的模型，如myapp.mymodel被转储。原因是，我有一些巨大的，300万条记录加上同样的应用程序中的数据集，我不想倾销。

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

从版本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

您还可以分离多个应用程序和模型命令行。这里是规范定义：

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] ...]]
