dr-dump 0.2

A Django data dump script generator

This is a Django data dump script generator.

It produces command line scripts usable within a Makefile or as a simple bash scripts to dump or load data with Django from the many app names you give it.

It need a dependancies map to know what is required to be dumped.

Maps

Currently it only have two maps one for “djangocms-2” and one for “djangocms-3” projects, and so it only knows about:

• Django contrib auth;

• Django sites;

• emencia.django.countries;

• contact_form;

• DjangoCMS and its common plugins;

• Zinnia;

• Porticus;

• South;

• django-tagging;

• django-taggit;

• easy-thumbnails;

• django-filer;

• django-google-tools;

• emencia-django-socialaggregator;

• emencia-django-slideshows;

Note : Many app depends on Django’s content types but we don’t matter because it is automatically filled by Django and we should never try to dump/load it.

Format

• Dumps order does matter to respect module’s dependancies;

• model or dependancy names can be string or either a list of names, take care that string is splitted on white spaces, if you use excude flag like ‘-e’ with your model names, allways use a list;

• Circular dependancies is possible;

Sample map :

[
    ('DUMP_NAME_KEY', {
        'use_natural_key': true,
        'models': 'mymodel',
        'dependancies': [],
    }),
]

Where :

DUMP_NAME_KEY

Is the dump entry name, can be anything but commonly this is the app package name, this is what is used in embedded map files.

use_natural_key

A boolean to define if the dump can use natural key, if not defined, a dump entry is assumed to support natural key.

models

Is either a string of the model name or a list model names. Django accept either an app name from which it will take all its models, or a specific app model.

dependancies

Either a string of another dump names to depends of. They will be taken also even if they haven’t been explicitely requested from user.
