If you want to add timestamps here a three options that you can take.
First let's create a new project and a new app.
-> % django-admin startproject blogproject && cd blogproject -> % python manage.py startapp blog
let's add the new app blog to our installed apps
Now we can start creating our model. We will have four fields: title, description, updated, created
If you planned to use these fields often in other Models. i.e. Comments, Like, ShoppingCart etc. It would be smarter keep things DRY
There is an awesome package called django-model-utils. If you planned to use more than one of the functionnalities offers in this package i.e. StatusField, FieldTracker you might as well use this package to add the fields created and updated
-> % pip install django-model-utils
After we will import it in your models.py
