问题 we have a Django 1.4.5 project with a PostgreSQL 9.3 backend. Unfortunately we are facing the problems when attempting to create fixtures for one of the apps (which is called sddb ). The database is full of objects that belong to sddb app: (venv)[root@dl380p1 team112]# ./manage.py shell >>> from sddb.models.media import Metadata >>> len(Metadata.objects.all()) 22916 However the dumpdata output is empty: (venv)[root@dl380p1 team112]# ./manage.py dumpdata sddb [] Explicit pointing of database

Django dump data for a single model?

由 ε祈祈猫儿з 提交于 2019-12-17 15:05:39
问题 Can I perform a dumpdata in Django on just a single model, rather than the whole app, and if so, how? For an app it would be: python manage.py dumpdata myapp 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. 回答1: As of version 1.1 and greater, the Django dumpdata management command allows you to dump data from individual tables: ./manage.py dumpdata

问题 I'm trying to dump my data to SQL statements. the django-admin.py dumpdata provides only json,xml,yaml. so: does someone know a good way to do it?!

Use Django dumpdata to dump a subset of overall data?

问题 I'm trying to use dumpdata to generate JSON for a database that is sufficiently large for django to take a long, long time to output. Is there any way to dump only a subset of the fields; say, 100, for testing? I'm using MySQL and Django 1.0. 回答1: A 3rd party django app, django-test-utils contains a makefixture command implementation which is basically a smarter dumpdata. You can specify exact model names with ID ranges to export (and it will follow related objects) Example: manage.py

Django backup strategy with dumpdata and migrations

由 烂漫一生 提交于 2019-11-30 21:25:29
As in this question , I set up a dumpdata -based backup system for my database. The setup is akin to running a cron script that calls dumpdata and moves the backup to a remote server, with the aim of simply using loaddata to recover the database. However, I'm not sure this plays well with migrations . loaddata now has an ignorenonexistent switch to deal with deleted models/fields, but it is not able to resolve cases where columns were added with one-off defaults or apply RunPython code. The way I see it, there are two sub-problems to address: Tag each dumpdata output file with the current
