在 Eloquent ORM 中使用 find 选择特定的列

Question

In Laravel how can I get specific columns using find? I know you can do it with get like this:

$user = User::where('u_id', '=', 1)
        ->get(['firstname', 'lastname']);

Is there a way to do it with find? This is what I currently have:

$user = User::find(1);

Answer 1

You have two options.

First, you can pass the columns to select as the second parameter to find() :

$user = User::find(1, ['firstname', 'lastname']);

Second, although somewhat specialized, find() is just the method used to execute the query, so you can modify the query as normal beforehand (add selects, wheres, orders, etc.). Therefore, you can just add a select() before you execute the find() :

$user = User::select(['firstname', 'lastname'])->find(1);

Answer 2

Here is another way, similar to @patricus.

$did = User::findOrFail($id, ['first_name', 'last_name']);
