Pay special attention to the names of the tables in the calls to the on() method. I have changed them

don’t seem to take into account the name of the table on which the constrains are being created.
Apart from the integer fields (which we’ve seen before); these pivot tables also have foreign keys,
with constraints. These are common features of relational databases, as they help to maintain
referential integrity among database entities.
.
These migrations specify foreign key constraints. This means the database will require valid foreign
keys when you insert and update rows in these tables. Your seeder class needs to provide these valid
ID values, or you should remove the constraints (references(‘id’)…onDelete(‘cascade’)).
With all these migration files created; we have only to migrate them to the database with:
1 php artisan migrate
(This assumes you have already configured the database connection details, in the configuration
files.)
Generating Seeders
Seeders are next on our list. These will provide us with starting data; so our API responses don’t
look so empty.
1 php artisan generate:seed Category
2 php artisan generate:seed Sponsor
These commands will generate stub seeders, and add them to the DatabaseSeeder class. I have gone
ahead and customised them to include some data (and better formatting):
