BadMethodCallException in Builder.php Linie 2405: Aufruf der undefinierten Methode Illuminate \ Database \ Abfrage \ Builder :: addEagerConstraints()

Question

Wenn ich auth()->user()->roles() mit Kesselflicker verwenden funktioniert es ohne Probleme, aber wenn ich es auf der Webseite verwenden, selbst ich :

BadMethodCallException in Builder.php line 2405: 
Call to undefined method Illuminate\Database\Query\Builder::addEagerConstraints() 

Was bedeutet das, was könnte der Grund dafür sein? Hier ist das zugehörige Modell:

class User extends Authenticatable 
{ 
    public function roles(){ 
     return Role::where('id', 6); 
    } 
} 

Ich benutze Laravel 5.2 und der vollständige Fehler ist wie folgt.

PS: Ich denke, das Problem hat etwas mit der Art zu tun, wie ich es in anderen Teilen der Website verwende. Deshalb funktioniert es beim Basteln. die anderen Teile sehen aus, als ob sie das Ergebnis der Form Relation Obj erfordern, die ich nach der Where-Abfrage nicht bereitstellen kann.

dies ist die dd der normalen Beziehung $this->belongsToMany(Role::class);

BelongsToMany {#971 ▼ 
    #table: "role_user" 
    #foreignKey: "user_id" 
    #otherKey: "role_id" 
    #relationName: "roles" 
    #pivotColumns: [] 
    #pivotWheres: [] 
    #pivotWhereIns: [] 
    #pivotCreatedAt: null 
    #pivotUpdatedAt: null 
    #query: Builder {#996 ▶} 
    #parent: User {#319 ▶} 
    #related: Role {#812 ▶} 
} 

und dies ist die return Role::where('id', 6); ein

Builder {#812 ▼ 
    #query: Builder {#317 ▶} 
    #model: Role {#997 ▶} 
    #eagerLoad: [] 
    #macros: [] 
    #onDelete: null 
    #passthru: array:11 [▶] 
    #scopes: [] 
    #removedScopes: [] 
} 

sie ganz anders aussehen verändert und dies kann der Grund.

Als @SimonSvensson gefragt, hier ist meine Comment Modell

class Comment extends Model 
{ 

    /** 
    * Fields that can be mass assigned. 
    * 
    * @var array 
    */ 
    protected $fillable = ['active', 'user_id', 'text', 'url']; 

    /** 
    * Comment morphs to models in commentable_type. 
    * Get all of the owning commentable models. 
    * 
    * @return \Illuminate\Database\Eloquent\Relations\MorphTo 
    */ 
    public function commentable() 
    { 
     // morphTo($name = commentable, $type = commentable_type, $id = commentable_id) 
     // requires commentable_type and commentable_id fields on $this->table 
     return $this->morphTo(); 
    } 

    /** 
    * Query scope ofWebsite. 
    * 
    * @param \Illuminate\Database\Eloquent\Builder 
    * @return \Illuminate\Database\Eloquent\Builder 
    */ 
    public function scopeOfWebsite($query) 
    { 
     return $query->where(function($q){ 
      $q->whereNull('commentable_id')->whereNull('commentable_type'); 
     }); 
    } 

    /** 
    * Comment belongs to User. 
    * 
    * @return \Illuminate\Database\Eloquent\Relations\BelongsTo 
    */ 
    public function user() 
    { 
     // belongsTo(RelatedModel, foreignKey = user_id, keyOnRelatedModel = id) 
     return $this->belongsTo(User::class); 
    } 

} 

Answer 1

Es sieht aus wie Sie die user.roles Beziehung zu eifrig laden sind versucht, aber es ist keine richtige Beziehung, es ist nur ein Methode, die einen Aufruf von Role :: where (...) aufruft. Beziehungsmethoden geben normalerweise etwas wie $this->hasMany(Role::class) zurück.
