Argument 1 passed to Illuminate\Database\Eloquent\Relations\HasOneOrMany::update() must be of the type array, object given
提问by Agus Suparman
I want to update a data in the database i have controller
我想更新我有控制器的数据库中的数据
public function update(Identity $identity, Request $request)
{
$data = new Identity();
$data->date = $request['date'];
$data->code = $request['code'];
$data->name = $request['name'];
$request->user()->identity()->update($data);
Session::flash('flash_message', 'Update success.');
return redirect('identity.index');
}
Model Identity
模特身份
public function user()
{
// Each data is owned by only one user
return $this->belongsTo('App\User');
}
Model User
模型用户
public function identity()
{
// Each user will have a lot of data
return $this->hasMany('App\Identity');
}
And i found an error: Argument 1 passed to Illuminate\Database\Eloquent\Relations\HasOneOrMany::update() must be of the type array, object given.
我发现了一个错误：传递给 Illuminate\Database\Eloquent\Relations\HasOneOrMany::update() 的参数 1 必须是给定的对象类型数组。

You already have the Identity model with the route model binding. You can do one of the below.
您已经拥有带有路由模型绑定的 Identity 模型。您可以执行以下操作之一。
public function update(Identity $identity, Request $request)
{
$identity->date = $request['date'];
$identity->code = $request['code'];
$identity->name = $request['name'];
$identity->save();
Session::flash('flash_message', 'Update success.');
return redirect('identity.index');
}
Or (Make sure you set the $fillable property in the model for this to work)
或者（确保您在模型中设置了 $fillable 属性以使其正常工作）
public function update(Identity $identity, Request $request)
{
$identity->update([
'date' => $request['date'],
'code' => $request['code'],
'name' => $request['name'],
]);
Session::flash('flash_message', 'Update success.');
return redirect('identity.index');
}

This line
这条线
$data = new Identity();
creates an object. Below that you are setting its properties. Instead, it looks like you can pass your properties directly into the function:
创建一个对象。在此之下，您正在设置其属性。相反，您似乎可以将属性直接传递给函数：
public function update(Identity $identity, Request $request)
{
$request->user()->identity()->update(array($request));
...
}
Of course you might also want to restrict your request to just what's needed:
当然，您可能还想将您的请求限制在需要的范围内：
public function update(Identity $identity, Request $request)
{
$params = array_intersect_key(array($request), array_flip(['date', 'code', 'name']))
$request->user()->identity()->update($params);
...
}
