How to update a column as foreign key on laravel?

To update a column as a foreign key in Laravel, you can use the unsignedBigInteger method in your migration file. Here's an example:

1. Create a new migration file:

1

php artisan make:migration add_foreign_key_to_table_name

1. Open the newly created migration file and add the following code to update the column as a foreign key:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16

public function up()
{
    Schema::table('table_name', function (Blueprint $table) {
        $table->unsignedBigInteger('foreign_key_column')->nullable();

        $table->foreign('foreign_key_column')->references('id')->on('related_table_name');
    });
}

public function down()
{
    Schema::table('table_name', function (Blueprint $table) {
        $table->dropForeign(['foreign_key_column']);
        $table->dropColumn('foreign_key_column');
    });
}

1. Replace table_name with the name of your table, foreign_key_column with the name of the column you want to update as a foreign key, and related_table_name with the name of the related table.
2. Run the migration to apply the changes:

1

php artisan migrate

After running the migration, the specified column in your table will be updated as a foreign key referencing the related table.
