I am using Laravel 5.2.
How to write this query about "order by update time"?

There are 2 tables,users and articles,they have a "one-to-many" relationship,
I would want to query user's name and his/her article titles,and order by article's update time,
like this:

username    article titles                       update time
Lily        aaa-title-01;aaa-title-02;...        2016-04-20 12:00:00
Lucy        bbb-title-01;bbb-title-02;...        2016-04-19 12:00:00
Jim         ccc-title-01;ccc-title-02;...        2016-04-18 12:00:00

The update time is the user's latest article's update time, for example:

The first one, username is Lily, update time is 2016-04-20 12:00:00,it represents that Lily's latest article was updated at 2016-04-20 12:00:00.
The second one,it represents that Lucy's latest article was updated at 2016-04-19 12:00:00.
Lily's latest article is later than Lucy's,so, Lily is the first,Lucy is the second,and..,Jim is the third.

I writed the query like this:

$articles =User::whereHas('articles', function($query) {
            $query->where('status', 1); //status is 1 or 0, 1 is published,0 is not published.
        })->get();

This query could get the user and his/her articles,but could not order by update time above,how to do it?

Answer 1

Just add orderBy on the query and you should look good.

$articles =User::whereHas('articles', function($query) {
    $query->where('status', 1)->orderBy('update_time', 'desc');
})->get();
