Gruppe von auf zugehörigen Modell in CakePHP

Question

Ich arbeite in CakePHP 3.4

Ich habe zwei Modelle skills und skill_categories und ihre Verbindung sind wie

skill_categories->hasMany('skills'); 
skills->belongsTo('SkillCategories', 'joinType' => 'INNER') 

und skills ist ein Verein mit users mit dem

skills->belongsTo('users') 
users->hasMany('Skills') 

Ich muss alle zugehörigen skills des Benutzers vonauswählenTabelle Gruppierung von skills.skill_category_id die wie

Skill Category 1 
|-- Skill 11 
|-- Skill 12 
|-- Skill 13 
Skill Category 2 
|-- Skill 21 
|-- Skill 22 

oder wie

'skill_categories' => [ 
     'title' => 'Skill Category 1', 
     'id' => 1, 
     'skills' => [ 
      0 => [ 
       'title' => 'Skill 11', 
       'id' => 4, 
      ], 
      1 => [ 
       'title' => 'Skill 12', 
       'id' => 6, 
      ] 
     ], 
] 

führen produzieren, was ich tue ist: Methode 1

$user_skills = $this->Skills->find() 
     ->select(['Skills.skill_category_id', 'Skills.title', 'Skills.measure', 'SkillCategories.title', 'Skills.id']) 
     ->where(['Skills.user_id' => $user->id, 'Skills.deleted' => false, 'Skills.status' => 0]) 
     ->contain(['SkillCategories']) 
     ->group(['Skills.skill_category_id']); 

     foreach($user_skills as $s)debug($s); 

Aber dies wirft Fehler als

Error: SQLSTATE[42000]: Syntax error or access violation: 1055 Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'profPlus_db_new.Skills.title' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

Methode 2

$user_skills = $this->SkillCategories->find() 
     ->where(['Skills.user_id' => $user->id, 'Skills.deleted' => false, 'Skills.status' => 0]) 
     ->contain(['Skills']) 
     ->group(['SkillCategories.id']); 

     foreach($user_skills as $s)debug($s); 

Aber das gibt Fehler als

Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'Skills.user_id' in 'where clause'

Answer 1

Sie die Bedingungen in der enthalten passieren können! : D

$user_skills = $this->SkillCategories->find() 
    ->contain(['Skills' => function($q) use($user) { 
     return $q 
     ->select(['id', 'user_id', 'deleted', 'status', 'skill_category_id']) 
     ->where(['user_id' => $user->id, 'deleted' => false, 'status' => 0]); 
    }]) 
    ->group(['SkillCategories.id']);
