Laravel Data population

writing shims

PHP Artisan Make:seeder Usertableseeder

Modify the class that comes with the Laravel installation DatabaseSeeder , adding a database insert statement to the run method:

<?phpuse db;use illuminate\database\seeder;use Illuminate\database\eloquent\model;classDatabaseseeder extends seeder{/** * Run Database population * * @return void*/     Publicfunction Run () {db::table ('Users'),Insert (['name'= Str_random (Ten),            'Email'= Str_random (Ten).'@gmail. com',            'Password'= Bcrypt ('Secret'),        ]); }}

Using a model factory

Use the Help function factory to insert a record into the database.

Create 50 users and add an association to each user:

 Public function Run () {    factory ('app\user')->create ()  Each (function ($u) {        $u->posts ()->save (Factory ('app\post') Make ());    });}

Call an extra shim

In the DatabaseSeeder class, use call the method to perform an additional fill class

 Public function Run () {    model::unguard ();    $This->call (usertableseeder::class);    $This->call (poststableseeder::class);    $This->call (commentstableseeder::class);}

Run the Filler

--class=usertableseeder

You can also migrate:refresh populate the database with commands, which can also be rolled back and rerun the migration, which is useful when you need to fully rebuild the database:

PHP Artisan Migrate:refresh--seed
