10.3.2 Startup Data
Starting in Django 1.8, it became possible to pass the --name argument to makemigrations, allowing for the creation of a named empty migration file. Rather than creating a file (automatically named according to UTC date-time) and then renaming the file, we can issue a single commmand, as shown in Example 10.11.
Example 10.11: Shell Code
$ ./manage.py makemigrations --empty --name=startup_data organizer
Every data migration is going to feature the structure: We use the RunPython operation to call either a forwards or backwards Python function, as shown in Example 10.12.
Example 10.12: Project Code
organizer/migrations/0003_startup_data.py in f492ab1462
