Convert Abfrage von Abfrage-Generator t zu Eloquent Abfrage

Question

Hallo alle können Sie mir helfen?

Ich habe Abfrage wie folgt:

public function getByUser($userId,$activityId){ 
     return $journals = DB::table('personfamilies') 
      ->join('journals','personfamilies.id','=','journals.person_id') 
      ->join('journal_details','journals.id','=','journal_details.journal_id') 
      ->where([ 
       ['user_id','=',$userId], 
       ['activities_id','=',$activityId] 
      ]) 
      ->get(); 
    } 

, wie zu beredt zu konvertieren?

Modell PersonFamily.php

public function relationship(){ 
    return $this->hasOne(Relationship::class,'id','relationship_id'); 
} 

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

public function journal(){ 
    return $this->hasMany(Journal::class,'id','id'); 
} 

Modell Journal.php

public function jurnalDetails(){ 
      return $this->hasMany(JurnalDetail::class,'id'); 
     } 

     public function personfamily(){ 
      return $this->belongsTo(PersonFamily::class,'person_id','journal_id'); 
     } 

JournalDetail.php

public function journal(){ 
     return $this->belongsTo(Journal::class,'id'); 
    } 

Ich habe es so versucht, aber es funktioniert nicht richtig `` `

return $journal = PersonFamily::where([ 
      ['user_id','=',$userId] 
      ]) 
      ->with('journal','journal.jurnalDetails') 
      ->get(); 
``` 

Answer 1

Ich würde so etwas tun:

// A family has many family members 
public function familyMember() { 
    return $this->hasMany('App\FamilyMember'); 
} 

Family Modell:

Sie Familie, Family, Journal und JournalEntry Modelle

Familie Modell Unter der Annahme haben

// A family member belongs to exactly one family 
public function family() { 
    return $this->belongsTo('App\Family') 
} 

// A family member has exactly one journal 
public function journal() { 
    return $this->hasOne('App\Journal'); 
} 

Journal Modell:

// A journal belongs to exactly one family member 
public function familyMember() { 
    return $this->belongsTo('App\FamilyMember'); 
} 

// A journal has many journal entries 
public function journalEntries() { 
    return $this->hasMany('App\JournalEntry'); 
} 

JournalEntry Modell:

// A journal entry belongs to exactly one journal 
public function journal() { 
    return $this->belongsTo('App\Journal'); 
} 

dann Ihre Abfrage wird ziemlich einfach:

// If you need the whole Family 
$family = Family::find($familyId); 
// If you need all the family members that belong to a family 
$familyMembers = $family->familyMembers; 
// If you are looking for a particular family member 
$familyMember = FamilyMember::find($userId); 
// If you need the journal for a family member 
$journal = $familyMember->journal 
// If you need all the journal entries in a particular journal 
$journalEntries = $journal->journalEntries; 

Sie dann diese Variablen in Ihrer Sicht passieren kann und sie angezeigt werden je nach Bedarf.
