laravel nullable code example

Example 1: laravel foreign key

Schema::table('posts', function (Blueprint $table) {
    $table->unsignedBigInteger('user_id');

    $table->foreign('user_id')->references('id')->on('users');
});
OR
Schema::table('posts', function (Blueprint $table) {
    $table->foreignId('user_id')->constrained();
});

Example 2: laravel change column

Schema::table('users', function (Blueprint $table) {
    $table->string('name', 50)->nullable()->change();
});

Example 3: integer nullable laravel

$table->integer('banner_id')->nullable()->unsigned();

Example 4: laravel drop column

// To drop a column, use the dropColumn method on the schema builder.
// Before dropping columns from a SQLite database, you will need to add
// the doctrine/dbal dependency to your composer.json file and run the
// composer update command in your terminal to install the library:

Schema::table('users', function (Blueprint $table) {
    $table->dropColumn('votes');
});

Example 5: laravel create db table

php artisan make:migration create_users_table

Example 6: laravel migration integer

$table->bigInteger('votes');
