[英]Laravel Integrity constraint violation: 1052 Column 'id' in where clause is ambiguous
[英]Integrity constraint violation: 1052 Column 'prof_id' in where clause is ambiguous Laravel
我想做的事情很簡單,運行具有某些關系的查詢並為該關系提供where子句。該查詢假定要獲取具有相關關系的問題,但標簽上的where子句只會告訴獲得與標簽相關的問題已發送($ 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");
}
}
詢問
$allquestions = userQuestion::with('getanswer','getusername','getbounty','gettags')
->whereHas('gettags', function($q) use($value) {
$q->where('prof_id', '=', $value);
})
->orderBy('created_at','Desc')
->get();
問題是它給了我這個錯誤
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,如果我將列切換為qp_id (PrimaryKey),它將起作用,並且列來自即時通訊嘗試訪問的數據透視表
做了一些谷歌搜索,我所做的是:
在模型中用'prof_id'填充1次(因為我也有數據透視表的模型,做了同樣的事情)
2次嘗試=> where而不是wherehas
仍然卡住
謝謝你的幫助!
在兩個表中都有prof_id時,在字段中添加表名稱。
$allquestions = userQuestion::with('getanswer','getusername','getbounty','gettags')
->whereHas('gettags', function($q) use($value) {
$q->where('question_profskill.prof_id', '=', $value); //question_profskill or prof_skills
})
->orderBy('created_at','Desc')->get();
