Question

如何使用request->all()更新所有记录，我有很多列要更新。这是我用于创建方法的代码，我正在使用该方法插入多个运行良好的新记录。

public function store(Request $request)
{
    $teacher = new Teacher;
    $teacher::create($request->all());
    $teacher->save();
    return back()->with('message','Teacher Added Successfully!');
}

这是我尝试过的方法，但是不起作用，

public function update(Request $request, Teacher $teacher)
{
    $teachers=$request->all();
    $teacher->save();
    return back()->with('message','Record Successfully Updated!');
}

Answer 1

代替此：

public function update(Request $request, Teacher $teacher)
{
    $teachers = $request->all();
    $teacher->save();
    return back()->with('message', 'Record Successfully Updated!');
}

您必须尝试：

public function update(Request $request, Teacher $teacher)
{
    $input = $request->all();
    $teacher->fill($input)->save();
    return back()->with('message', 'Record Successfully Updated!');
}

假设您必须在fillable模型中创建Teacher属性。

我希望这会有所帮助。谢谢

public function update(Request $request, Teacher $teacher)
{
    /*
     * For the love of god, validate your data!!!
     */
    $attributes = $this->validate($request, $rules);
    $teacher->update($attributes);

    return ...
}
