【问题描述】:
我目前正在尝试在公司表中为 customer_no 添加验证。
public function rules()
{
$id = Company::where('customer_no', '=', $this->get('customer_no'))->first();
$id = $id['attributes']['id'];
return [
'customer_no' => 'required|unique:companies,customer_no,'.$id,
];
}
在添加一个具有现有 customer_no 的新公司后,我从唯一的数据库迁移中收到以下错误消息。
SQLSTATE[23000]: Integrity constraint violation:
1062 Duplicate entry 'abc' for key 'companies_customer_no_unique'
(SQL: update `companies` set `customer_no` = abc, `updated_at` = 2016-03-15 14:50:28 where `id` = 1)
但它应该将我重定向到上一页并显示错误消息。这已经适用于必填字段,变量 $id 包含公司的 id(使用 var_dump 检查)。
编辑:(companyController 存储)
/**
* Store a newly created resource in storage.
*
* @param ManageCompanyRequest $request
* @return Response
*/
public function store(ManageCompanyRequest $request)
{
$company = $request->all();
if(!(CompanyType::where('id','=',$request->company_type_id)->exists() || CompanyType::where('name', 'like', $request->company_type_id)->exists()))
$company['company_type_id'] = CompanyType::create(['name' => $request->company_type_id])->id;
else if(CompanyType::where('name', 'like', $request->company_type_id)->exists())
$company['company_type_id'] = CompanyType::where('name', 'like', $request->company_type_id)->first(['id'])->id;
$address = Address::create($request->all());
$company['address_id'] = $address->id;
Company::create($company);
return redirect('companies');
}
CompanyController 更新:
/**
* Update the specified resource in storage.
*
* @param \Illuminate\Http\Request $request
* @param int $id
* @return Response
*/
public function update(ManageCompanyRequest $request, $id)
{
if(!(CompanyType::where('id','=',$request->company_type_id)->exists() || CompanyType::where('name', 'like', $request->company_type_id)->exists()))
$request->company_type_id = CompanyType::create(['name' => $request->company_type_id])->id;
else if(CompanyType::where('name', 'like', $request->company_type_id)->exists())
$request->company_type_id = CompanyType::where('name', 'like', $request->company_type_id)->first(['id'])->id;
$company = Company::find($id);
Company::find($id)->update([
'company_type_id' => $request->company_type_id,
'customer_no' => $request->customer_no,
'name' => $request->name,
'comment' => $request->comment
]);
Address::where('id', '=', $company->address_id)->update([
'country_code_id' => $request->country_code_id,
'city' => $request->city,
'region' => $request->region,
'postal_code' => $request->postal_code,
'street' => $request->street
]);
return redirect('companies');
}
【问题讨论】:
-
您可以尝试在 Controller 的方法中添加 try catch 语句。这将防止代码产生如此丑陋的前端错误。你能在代码中添加控制器方法吗?
-
是否需要将 ID 提供给验证规则数组?我认为只指定 'customer_no' => 'required|unique:companies' 就足够了。您对该规则所做的实际上是强制验证器忽略提供的 ID。请参阅“强制使用唯一规则以忽略给定 ID”:laravel.com/docs/master/validation
-
编辑现有公司需要ID。为了更新条目,我必须忽略此特定条目的 customer_no。它适用于没有除外部分的商店,但不适用于更新。新增 companyController 的 store() 和 update()。
