First install roughage: pip install django-roughage
Assume that your app/models.py looks like this
class Book(models.Model):
title = models.CharField(max_length=255)
class BookReport(models.Model):
book = models.ForeignKey(Book)
grade = models.IntegerField()Then you define a seeds.py like the following:
from roughage import Seed
from app.models import Book, BookReport
class BookSeed(Seed):
model = Book
def querysets(self):
return [
Book.objects.filter(id__lt=3)
]
class BookReportSeed(Seed):
model = BookReport
def trim_app__book(self, queryset):
return queryset[:2]Then run
$ ./manage.py plant --seeds=seeds.py --file=dev_dump.json
dev_dump.json will contain all books with id < 3 and the first two book reports attached to those books.
You can now import this into another database with
$ ./manage.py reap dev_dump.json
