我目前正在嘗試爲公司表中的customer_no添加驗證。Laravel Eloquent獨特的驗證問題
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,
];
}
加入一家新公司與已經存在的CUSTOMER_NO我從獨特的數據庫遷移以下錯誤消息後。
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,它應該重定向到上一頁並顯示錯誤消息。這已經適用於必填字段,變量$ id包含公司的id(使用var_dump進行檢查)。
編輯:(companyController存儲)
/**
* 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');
}
您可以嘗試在Controller中的方法中添加try catch語句。這將防止代碼生成這樣一個醜陋的前端錯誤。你能夠將控制器方法添加到代碼? – Duikboot
您是否需要將ID提供給驗證規則數組?我認爲只是指出'customer_no'=>'必需|唯一:公司'就足夠了。你用這個規則做什麼實際上是迫使驗證者忽略提供的ID。請參閱「強制使用唯一規則忽略給定ID」:https://laravel.com/docs/master/validation – btl
編輯現有公司需要此ID。爲了更新條目,我必須忽略此特定條目的customer_no。它正在爲沒有除外部分的商店工作,但不適用於更新。 增加了companyController的store()和update()。 –
