Laravel Manual Update Timestamp
提问by Matt Pierce
I have a miscellaneous database table that is updated each time a user visits another user's profile. I'm having trouble creating a manual timestamp column though. Since I didn't create a model for this, I'm doing it manually which shouldn't be an issue because this database isn't accepting any user-generated input.
我有一个杂项数据库表，每次用户访问另一个用户的个人资料时都会更新该表。但是，我在创建手动时间戳列时遇到了麻烦。由于我没有为此创建模型，因此我是手动进行的，这应该不是问题，因为该数据库不接受任何用户生成的输入。
Migration:
移民：
public function up()
{
Schema::create('recently_visited', function (Blueprint $table) {
$table->increments('id');
$table->integer('visitor_id');
$table->integer('profile_id');
$table->integer('times_visited');
$table->timestamp('last_visit');
});
}
Controller:
控制器：
$visits = DB::table('recently_visited')
->where('profile_id',$user->id)
->where('visitor_id',Auth::user()->id)
->increment('times_visited')
->update(array('last_visit' => Carbon::now()));
I get the following error. Please help me understand, what is the integer this is being called on. Thanks!
我收到以下错误。请帮助我理解，这个被调用的整数是什么。谢谢！
Fatal error: Call to a member function update() on integer
致命错误：在整数上调用成员函数 update()
ANSWER:
回答：
I just needed to include all my updated within the increment() in the query builder.
我只需要在查询构建器的 increment() 中包含我的所有更新。
$visits = DB::table('recently_visited')
->where('profile_id',$user->id)
->where('visitor_id',Auth::user()->id)
->increment('times_visited', 1, ['last_visit' => Carbon::now()]);

increment()method doesn't return query builder instance but rather updates the record itself and returns an integer.
increment()方法不返回查询构建器实例，而是更新记录本身并返回一个整数。
You should be able to do this:
你应该能够做到这一点：
$visits = DB::table('recently_visited')
->where('profile_id',$user->id)
->where('visitor_id',Auth::user()->id)
->increment('times_visited', 1, array('last_visit' => Carbon::now()));
