Question

我知道phpmyadmin中没有该表但问题是我不知道该怎么做

代码

    public function DriverRefer($id)
{
    $driver = Driver::find($id);
    $query = ReferralDiscount::where([['referral_driver_id', '=', $id], ['referral_sender_id', '!=', 0]])->latest();
    $referral_details = $query->paginate(25);
    return view('merchant.driver.driver_refer', compact('referral_details', 'driver'));
}

Illuminate \ Database \ QueryException（42S22） SQLSTATE [42S22]：找不到列：1054“ where子句”中的未知列“ referral_driver_id”（SQL：从referral_discounts中选择count（*）作为聚合，其中（referral_driver_id = 4130和{{1} }！= 0））以前的例外 SQLSTATE [42S22]：找不到列：1054“ where子句”中的未知列“ referral_driver_id”（42S22）

Answer 1

我在App / Models中添加了一个名为DriverReferralDiscount的模型：

<?php

class DriverReferralDiscount extends Model
{
    protected $guarded = [];

    public function Driver()
    {
        return $this->belongsTo(Driver::class, 'referral_driver_id');
    }

    public function SenderDriver()
    {
        return $this->belongsTo(Driver::class, 'referral_sender_id');
    }

    public function getSenderDetails($driver_id)
    {
        $refer = ReferralDiscount::where([['referral_driver_id', '=', $driver_id], ['referral_sender_id', '!=', 0]])->get();
        return $refer;
    }

    public function getSenderCount($driver_id)
    {
        $refer = ReferralDiscount::where([['referral_driver_id', '=', $driver_id], ['referral_sender_id', '!=', 0]])->count();
        return $refer;
    }}

并将代码更改为

public function DriverRefer($id){
$driver = Driver::find($id);
$query = DriverReferralDiscount::where([['referral_driver_id', '=', $id], ['referral_sender_id', '!=', 0]])->latest();
$referral_details = $query->paginate(25);
return view('merchant.driver.driver_refer', compact('referral_details', 'driver'));}

然后我在phpmyadmin中添加了一个名为driver_referral_discounts的表，其列为：

id  
referral_driver_id  
referral_sender_id  
referral_offer  
referral_offer_value    
referral_available  
created_at  
updated_at

很抱歉，如果不清楚，但是我尽了最大努力，以防其他人得到帮助。
