Aap ek product create karne ke liye Laravel Form Request use kar rahe hain. Requirement hai:
Kaunsa rules() implementation correct hai?
public function rules(): array
{
return [
'name' => ['required', 'string', 'max:255'],
'price' => ['required', 'numeric', 'min:0'],
'supplier_email' => ['required', 'email'],
];
}Ye correct implementation hai. name ko required string aur 255 character limit ke saath validate kiya gaya hai. price ko numeric aur zero se kam na hone ke liye validate kiya gaya hai. supplier_email ko required email value ke roop me validate kiya gaya hai.
Form Request validation ka advantage ye hai ki validation rules controller se alag dedicated class me organized rehte hain.
public function rules(): array
{
return [
'name' => ['nullable'],
'price' => ['nullable'],
'supplier_email' => ['nullable'],
];
}Ye requirement ke opposite hai, kyunki tino fields required hain. Nullable field missing hone par validation pass kar sakti hai.
public function rules(): array
{
return [
'name' => ['required'],
'price' => ['required'],
'supplier_email' => ['required'],
];
}Required rule presence check karta hai, lekin question me string length, numeric constraint aur valid email format bhi required hai. Isliye ye incomplete implementation hai.
public function rules(): array
{
return [
'name' => ['email'],
'price' => ['email'],
'supplier_email' => ['numeric'],
];
}Rules field ke expected data type aur format se match nahi kar rahe. Name email nahi hai aur supplier email ko numeric validate karna logically incorrect hai.
{{ validator($request)->validate() }}Validation responsibility ko presentation template me rakhna maintainability aur architecture dono ke liye poor approach hai. Form Request ya controller/request boundary par validation karna chahiye.
public function rules(): array
{
return [];
}Empty rules validation requirements ko ignore karegi. Invalid values application layer tak pahunch sakti hain aur business logic unreliable ho sakta hai.
