Requirements

• Django 2.2+

• Python 3.6+

Installation

You can install data_seeder using pip

pip install django-data-seeder

Quick Start

1. Add data_seeder to your INSTALLED_APPS in settings.py

   INSTALLED_APPS = [
     ...
   
     'data_seeder',
   ]

2. Seed data with the following command

   python manage.py seeddata [options] app.models.Model [app.models.Model2, ...]

   This will generate a single seed for each model provided.

Advanced Usage of the Management Command

In addition to generating single seeds for models, the seeddata can also create as many seeds as you want

python manage.py seeddata --seeds=N apps.model.Model

This will generate N seeds for apps.model.Model

Another option that you can use is to generate related models. This is used for foreign key references where we need to recursively generate seeds for models. The default behaviour for this is disabled, meaning that a randomly selected existing model will be used for the related model field. We override this by doing the following

python manage.py seeddata --generate-related apps.model.Model

One limitation to this behavior is that the data seeder will not generate a related model if the relation is the model itself. This would cause an infinite recursion.

For more information about the seeddata command, please look at the help page.

python manage.py help seeddata

Using the Django Admin Site

For convenience, you can also use the out-of-the-box Administrator site included with Django to generate your seeds.

To do this, you must register your models with the admin site using the custom ModelAdmin class provided. For example, in admin.py for your app

from django.contrib import admin

from .models import MyModel
from data_seeder.admin import DataGeneratorAdmin

admin.site.register(MyModel, DataGeneratorAdmin)

This will add a button to the model page in the admin site to generate data, which will provide you with the same options available in the management command.

You can also register your models using a decorator instead

from django.contrib import admin

from .models import MyModel
from data_seeder.admin import data_generator_register

@admin.register(MyModel)
@data_generator_register
class MyModelAdmin(admin.ModelAdmin):
    pass
