Laravel Model->save() returns false but no error

提问by Lyon

Normally when I call Model->save(), it creates the new record in the database successfully. I'm trying to debug a situation when nothing happens and Model->save()returns false. How do I find out what's happening?

通常当我调用时Model->save(),它会成功地在数据库中创建新记录。我正在尝试调试没有任何反应并Model->save()返回 false 的情况。我如何知道发生了什么?

$user = new User;
$user->fields = 'example';
$user->save(); // returns false

Running this does not show any insert queries.

运行它不会显示任何插入查询。

dd(DB::getQueryLog());

But if I var_dump($user), I correctly get all the fields properly saved in the object.

但是,如果我var_dump($user)正确地将所有字段正确保存在对象中。

Thanks!

谢谢!

To get the insert queries when $user->save();error, you can try to catch the exception like this:

要在$user->save();出错时获取插入查询,您可以尝试像这样捕获异常:

    try{
       $user = new User;
       $user->fields = 'example';
       $user->save(); // returns false
    }
    catch(\Exception $e){
       // do task when error
       echo $e->getMessage();   // insert query
    }

Hope this helps :)
