you can see how to prepare django project on the previous blog post series. if you want more details about how to make django project, see the links below.

in this blog post, we won’t see how to install and configure django project. just we’ll see simply to prepare the project to be able to talk about data-seed.

connect database and migrate the tables to see the blog below.

after connecting the database, execute the command below to create an administrator(superuser).

Prepare Master Data

after doing Prepare django Proejct section, you can see blog/ model like below.

from django.db import models
from django.utils import timezone

class Post(models.Model):
    author = models.ForeignKey('auth.User', on_delete=models.CASCADE)
    title = models.CharField(max_length=100)
    content = models.TextField()
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    published_at = models.DateTimeField(blank=True, null=True)

    def publish(self):
        self.published_at =

    def __str__(self):
        return self.title

we’ll prepare the master data for this model and insert data to database(Seed). create and modify blog/fixtures/posts-data.json file like below.

    "model": "",
    "fields": {
      "author": 1,
      "title": "test2",
      "content": "test2",
      "created_at": "2019-06-04T15:43:29.899",
      "updated_at": "2019-06-04T15:43:29.899",
      "published_at": "2019-06-04T15:43:28"
    "model": "",
    "fields": {
      "author": 1,
      "title": "test1",
      "content": "test1\r\n\r\ntest1",
      "created_at": "2019-06-04T15:43:19.760",
      "updated_at": "2019-06-04T15:43:19.760",
      "published_at": "2019-06-04T15:43:18"
