违反完整性约束:1052 where子句不明确的列'prof_id'Laravel

[英]Integrity constraint violation: 1052 Column 'prof_id' in where clause is ambiguous Laravel

我想做的事情很简单,运行具有某些关系的查询并为该关系提供where子句。该查询假定要获取具有相关关系的问题,但标签上的where子句只会告诉获得与标签相关的问题已发送($ value)。

userQuestion模型

<?php

namespace App;

class userQuestion extends Model
{
    protected $table = "question";
    public $primaryKey = "question_id";
    protected $fillable = ['question_id'];

    public function gettags() {
        return $this->belongsToMany('App\Profskills','question_profskill',"question_id","prof_id");
    }
}

询问

$allquestions = userQuestion::with('getanswer','getusername','getbounty','gettags')
    ->whereHas('gettags', function($q) use($value) {
        $q->where('prof_id', '=', $value); 
    })
    ->orderBy('created_at','Desc')
    ->get();

问题是它给了我这个错误

 QueryException in Connection.php line 729:
 SQLSTATE[23000]: Integrity constraint violation: 1052 Column 'prof_id' in          
 where clause is ambiguous (SQL: select * from `question` where exists 
 (select * from `prof_skills` inner join `question_profskill` on 
 `prof_skills`.`prof_id` =  `question_profskill`.`prof_id` where `question_profskill`.`question_id` =    `question`.`question_id` and 
 `prof_id` = 1) order by `created_at` desc)

列存在,如果我将列切换为qp_id (PrimaryKey),它将起作用,并且来自即时通讯尝试访问的数据透视表

做了一些谷歌搜索,我所做的是:

在模型中用'prof_id'填充1次(因为我也有数据透视表的模型,做了同样的事情)

2次尝试=> where而不是wherehas

仍然卡住

谢谢你的帮助!

在两个表中都有prof_id时,在字段中添加表名称。

$allquestions = userQuestion::with('getanswer','getusername','getbounty','gettags')
           ->whereHas('gettags', function($q) use($value) {

       $q->where('question_profskill.prof_id', '=', $value); //question_profskill or prof_skills
})
->orderBy('created_at','Desc')->get();
