Laravel关系计数[关闭]

Question

I know title seems a little complicated, but what I want is simple

• Users (users) have comments (comments)
• To fetch users' comments, I'm using a hasMany relationship
• I'm creating a filter system, so I only want to fetch users who have posted at least 1 comment

Answer 1

Use has():

$users = User::has('comments')->get();

Or eager load the users comment models:

$users = User::has('comments')->with('comments')->get();
