我目前正在尝试为公司表中的customer_no添加验证。Laravel Eloquent独特的验证问题
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,
];
}
加入一家新公司与已经存在的CUSTOMER_NO我从独特的数据库迁移以下错误消息后。
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)
但是相反,它应该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进行检查)。
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');
}
您可以尝试在Controller中的方法中添加try catch语句。这将防止代码生成这样一个丑陋的前端错误。你能够将控制器方法添加到代码? – Duikboot
您是否需要将ID提供给验证规则数组?我认为只是指出'customer_no'=>'必需|唯一:公司'就足够了。你用这个规则做什么实际上是迫使验证者忽略提供的ID。请参阅“强制使用唯一规则忽略给定ID”:https://laravel.com/docs/master/validation – btl
编辑现有公司需要此ID。为了更新条目,我必须忽略此特定条目的customer_no。它正在为没有除外部分的商店工作,但不适用于更新。 增加了companyController的store()和update()。 –
