How do you use a BIGINT as an Auto-Incrementing Primary Key in Laravel 4

Question

I am trying to mimic wordpress\' primary key size which is BIGINT(20) but it seems that laravel doesn\'t have a native function to do this.. I saw a page in the laravel foru

Answer 1

You most likely forgot to also set the type of your role_id foreign key as BIGINT(20) as well. This isn't really a Laravel issue, but rather MySQL's.

By the way, Laravel does have a native function to do this:

$this->bigIncrements('id');

This takes care of making it unsigned, auto increment and primary key.

Answer 2

When using bigInteger() also applying it to foreign key in some table, make sure you connect it properly with unsignedBigInteger(),

public function up()
{
        Schema::create('create_this_table_after_users', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->unsignedBigInteger('user_id');
           // Other Columns
        });
        Schema::table('create_this_table_after_users', function($table) {
            $table->foreign('user_id')->references('id')->on('users');
            // Other Constraints 
        });
}
