插入使用laravel 6不工作(函数存储)数组到字符串的转换

Question

我试图插入一个annn，但它给了我错误Array to string conversion。我知道所有字段都不是强制性的，因为插入是根据刀片edit中选择的subcategory_id完成的

AnnancesController.php

public function store(Request $request)
{

$request->validate([  
'category_id'=>['bail','required',],
'souscategory_id'=>['bail','required',],
'entreprise'     =>['bail','exclude_unless:souscategory_id,1','required','string','min:2','max:255'],
'domaine'     =>['bail','exclude_unless:souscategory_id,1','required','string'],
'contrat'     =>['bail','exclude_unless:souscategory_id,1','required','string',],
'niveaua'     =>['bail','exclude_unless:souscategory_id,1','required','string'],
'poste'     =>['bail','exclude_unless:souscategory_id,2','required','string'],
'marquem'   =>['bail','exclude_unless:souscategory_id,7','required','string'],
'marque'    =>['bail','exclude_unless:souscategory_id,8','required','string'],
'modele'    =>['bail','exclude_unless:souscategory_id,8','required','string'],
'annee'     =>['bail','exclude_unless:souscategory_id,8','required','string'],
'km'        =>['bail','exclude_unless:souscategory_id,8','required','numeric'],
'carburant'           =>['bail','exclude_unless:souscategory_id,8','required','string','min:2','max:255'],
'puissance'           =>['bail','exclude_unless:souscategory_id,8','required','string','min:2','max:255'],
'titre'          =>['bail','exclude_unless:souscategory_id,1','required','string','min:2','max:255'],
'description'    =>['bail','exclude_unless:souscategory_id,1','required','string','min:30','max:255'],
'prix'    =>['bail','exclude_unless:souscategory_id,6','required','min:1','max:12'],
'image'          =>['bail','exclude_unless:souscategory_id,1','required','mimes:jpeg,jpg,png,gif,svg','max:2048'],
'images.*'       =>['bail','exclude_unless:souscategory_id,1','required','mimes:jpeg,jpg,png,gif,svg','max:2048'], 
//2 emploi/

]); 
if($request->hasFile('image'))
{
$path = $request->image->store('annonces');
$request->image = $path;
}
$request->user_id = Auth::user()->id;
$Annonce = new Annonce($request->all());
$Annonce->save();
return Redirect::to("annonces")
->withSuccess('Great! file has been successfully uploaded.');
}

Answer 1

要在Laravel中从$request创建一个新元素，您需要按照以下步骤进行，并将$request的每个值分配给Announce对象的每个属性：

$request->user_id = Auth::user()->id;
$Annonce = new Annonce();
$Annonce->user_id = $request->user_id;
$Annonce->some_column = $request->some_column;
$Account->save();

Answer 2

您可以通过以下方式尝试：

use AppModelsAnnounce;
............................
$data = $request->all();
if ($request->hasFile('image')) {
$path = $request->image->store('annonces');
$data['image'] = $path;
}
$data['user_id'] = Auth::user()->id;
Announce::create($data);
return Redirect::to("annonces")
->withSuccess('Great! file has been successfully uploaded.');

请确保在应用程序上导入了正确的模型命名空间

Answer 3

虽然不建议修改请求，但您应该这样做：

$request->request->add(['image' => $path, 'user_id' => Auth::user()->id]);

或通过

$request = array_merge($request->all(), ['image' => $path, 'user_id' => Auth::user()->id]));
