laravel如何将字段更新到数据库

问题描述：

这是我的代码

$admin = Admin::find(25);
        $admin->picture = $destination;
        $admin->save();

但是当我执行它时，picture字段保留为NULL，例如images/admin_20

but when I execute it, the picture field is keep NULL for example images/admin_20

destination是图像位置的字符串.

the destination is a string to the location of the image.

我已经尝试过->update()，但是什么也没有保存.

I already tried ->update() but also nothing becomes saved.

你能帮我吗

我数据库中的picture列是varchar(255) utf8_unicode_ci

答

最后我找到了问题，三天的时间解决了这个愚蠢的错误

Finally I found the problem, three days working to this silly mistake

我数据库中的ID列应该是id

the ID column in my database should have been id
