Php Laravel ORM关系仅在id上返回null>；1.

我最近发现了一个问题。 我有2个模型、文章和用户。我已经定义了这样的模型关系

User.php

     public function articles()
 {
     return $this->hasMany(Articles::class,'written_by');
 }

Article.php

    public function writer()
{
    return $this->hasOne(User::class, 'id');
}

问题是，只有在阅读id为1的文章时，才能访问该关系

url.com/clanek/1

但是当url是url.com/clanek/2

仅给出“null”。

按以下方式更改关系

User.php

public function articles()
{
   return $this->hasMany(Articles::class,'written_by','id');
}

public function articles(){
    return $this->hasMany(Article::class,'written_by','id');
}

public function writer(){
    return $this-> belongsTo(User::class);
}

而在Article.php中它将属于to

public function writer()
{
   return $this->belongsTo(User::class,'written_by','id');
}

---

更改关系如下

User.php

public function articles()
{
   return $this->hasMany(Articles::class,'written_by','id');
}

public function articles(){
    return $this->hasMany(Article::class,'written_by','id');
}

public function writer(){
    return $this-> belongsTo(User::class);
}

而在Article.php中它将属于to

public function writer()
{
   return $this->belongsTo(User::class,'written_by','id');
}

你必须这样改变

User.php

public function articles()
{
   return $this->hasMany(Articles::class,'written_by','id');
}

public function articles(){
    return $this->hasMany(Article::class,'written_by','id');
}

public function writer(){
    return $this-> belongsTo(User::class);
}

Article.php

public function articles()
{
   return $this->hasMany(Articles::class,'written_by','id');
}

public function articles(){
    return $this->hasMany(Article::class,'written_by','id');
}

public function writer(){
    return $this-> belongsTo(User::class);
}

User.php

}

public function writer(){
    return $this-> belongsTo(User::class);
}

Article.php

public function articles()
{
   return $this->hasMany(Articles::class,'written_by','id');
}

public function articles(){
    return $this->hasMany(Article::class,'written_by','id');
}

public function writer(){

}
