1# The easiest way to create a model instance is using the 
2# make:model Artisan command:
3
4php artisan make:model Flight

6# If you would like to generate a database migration when you 
7# generate the model, you may use the --migration or -m option:

9php artisan make:model Flight --migration
10php artisan make:model Flight -m
