Question

我已经在我的网站中为管理员建立了一个cms界面。管理员可以使用表格添加\编辑用户信息。当我发送编辑表单时，我不断收到此错误：Column not found: 1054 Unknown column 'updated_at' in 'field list'，这表明数据库更新正在尝试保存所有请求索引（其中包含来自其他表的列的值），而不仅仅是我自己的尝试更新。

我已设法将问题跟踪到$user_role->save();行中。上面的行完成了应做的工作（找到相应的user_role并更改其值）。

这是我的代码

模型

static public function update_user($request, $id){
        
        $image_name = '';

        if( !empty($request['profile_image']) && $request->hasFile('profile_image') && $request->file('profile_image')->isValid() ){

            $file = $request->file('profile_image');
            $image_name = date('Y.m.d.H.i.s') . '-' . $file->getClientOriginalName();
            $request->file('profile_image')->move( public_path() . '/images/profile-images/' , $image_name);
            $img = Image::make( public_path() . '/images/profile-images/' . $image_name );
            $img->resize(370, null, function ($constraint) {
                $constraint->aspectRatio();
            });
            $img->save();

        }
        $user = self::find($id);
        $user->name = $request['name'];
        $user->email = $request['email'];
        $user->phone = $request['phone'];
        if( !empty($request['password']) ){
            $user->password = bcrypt($request['password']);
        }
        if(!empty($image_name)){
            $user->profile_image = $image_name;
        }
        if( !empty($request['role_id']) ){
            $user_role = Users_role::find($id);
            $user_role->role_id = $request['role_id'];
            $user_role->save();
        }
        $user->save();
        Session::flash('sm', 'Your profile has been updated');
        Session::flash('sm-position', 'toast-top-center');
        Session::put('user_name', $request['name']);
    }

laravel给出的错误图片

我应该提一下，如果我注释掉这段代码：

        if( !empty($request['role_id']) ){
            $user_role = Users_role::find($id);
            $user_role->role_id = $request['role_id'];
            $user_role->update();
        }

所有值都正确保存。

Answer 1

如果您的users表中没有created_at和updated_at列，则应设置：

public $timestamps = false;

在您的User模型中。

Laravel默认情况下假定您具有表的那些字段。因此，无论何时创建/更新记录，它都会自动设置/更新这些字段。

或者，您可以更新表结构以添加这些字段，然后Laravel将自动处理这些字段（在这种情况下，请勿将timestamps设置为false）。
