在创建Paginator实例时将原始选择语句传递给laravel Eloquent

Question

Pagination in Laravel is super easy. I simply go:

$posts = Post::where( .... );
$posts->paginate(20, ['ID', 'title', 'body'], ....);

I am trying to replace the ID,title,body array with: ID, title, LEFT(body, 200) But Laravel doesn't accept that! I found out that I should use this instead:

connection()->raw('ID, title, LEFT(body, 200) AS body');

For this to work, but the paginate method only accepts an array. Is there a way around it?

Answer 1

Do this:

$posts = Post::where( .... );
$posts->paginate(20, ['ID', 'title', \DB::raw('LEFT(body, 200) AS body')], ....);
