У меня есть две модели Member
и Saving
с
Member('id','name')
Saving('id','member_id','amount','month')
Я должен ограничить дублирование записи о сохранении члена за данный месяц.
Member.php
class Member extends Model
{
protected $fillable=['name','address','phone'];
public function loan()
{
return $this->hasOne(Loan::class,'member_id','id');
}
public function savings()
{
return $this->hasMany(Saving::class,'member_id','id');
}
}
Saving.php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Saving extends Model
{
protected $fillable=['amount','month','member_id'];
public function member()
{
return $this->belongsTo('App\Member','member_id','id');
}
}
Можно ли реализовать ограничение, используя функции в модели или контроллере?
РЕДАКТИРОВАТЬ:
Вот как я пытался.
SavingController.php
public function addSaving(Request $request){
if($request->isMethod('get')){
$memberData = Member::all();
return view($this->_pagePath.'saving.addsaving',compact('memberData'));
//return redirect()->back();
}
if($request->isMethod('post')){
$this->validate($request,[
'amount' => 'required',
'month' => 'required'
]);
$data['amount'] = $request->amount;
$data['month'] = $request->month;
$data['member_id']= $request->name;
$member= Member::find(1);
if($member->savings()->where('month',$request->month)->exists())
{
return 'Savings for this month are already added.';
}
else
{
if(DB::table('savings')->insert($data)){
return redirect()->route('saving')->with('success','data was successfuly inserted');
}
}
}
}
