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子句只会告诉与已发送的代码($ 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");
}
}
查询
$allquestions = userQuestion::with('getanswer','getusername','getbounty','gettags')
->whereHas('gettags', function($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)
该列存在,并且如果我将该列切换为 qp_id (PrimaryKey),它将起作用,并且列来自我试图访问的数据透视表
做了一些谷歌搜索,我所做的是:
在模型中可以用'prof_id'填充的1项(因为我也有数据透视表的模型,做了同样的事情)
2-try => where而不是where
仍然停留,
感谢您的帮助!

在两个表中都有prof_id时,在字段中添加表名。
$allquestions = userQuestion::with('getanswer','getusername','getbounty','gettags')
->whereHas('gettags', function($q) use($value) {
$q->where('question_profskill.prof_id', '=', $value); //question_profskill or prof_skills
})
->orderBy('created_at','Desc')->get();
