У меня есть форма для ввода пользователем информации для регистрации в конгрессе.
В форме есть эта часть для отображения обязательного атрибута, только если в пользовательском вопросе есть столбец «обязательный» со значением «1»:
@foreach($selectedType['questions'] as $customQuestion)
<div class="form-group">
<label for="participant_question">{{$customQuestion->question}}</label>
<p>REQUIRED VALUE:::::: {{$customQuestion->required }}</p>
<p>REQUIRED VALUE:::::: {{$customQuestion->ticket_type->pivot->required}}</p>
<p>REQUIRED VALUE:::::: {{$customQuestion}}</p>
<input type="text" @if($customQuestion->required == "1") required @endif
class="form-control" name="participant_question[]" value="">
</div>
@endforeach
Но это не работает, потому что "{{$customQuestion->required }}
" в "<p>REQUIRED VALUE:::::: {{$customQuestion->required }}</p>
" равно null
, ничего не показывает.
"{{$customQuestion}}
" показывает:
{"id":1,
"question":"Whats your phone?",
"type":"text","congress_id":1,
"pivot":{"ticket_type_id":1,
"question_id":1},
"ticket_type":[{"id":1,
"name":"test",
"congress_id":1,
"pivot":{"question_id":1,
"ticket_type_id":1,"required":1}}]}
"{{$customQuestion->ticket_type->pivot->required}}
" показывает: "Property [pivot] does not exist on this collection instance.
".
Знаете ли вы, почему $customQuestion->required
равен нулю?
Модели, имеющие отношение к вопросу:
// Congress model
class Congress extends Model
{
// A congress has many ticket types
public function ticketTypes(){
return $this->hasMany('App\TicketType', 'congress_id');
}
}
// TicketType Model
class TicketType extends Model
{
public function congress(){
return $this->belongsTo('App\Congress');
}
public function questions(){
return $this->belongsToMany('App\Question', 'ticket_type_questions');
}
}
// TicketTypeQuestion model
class TicketTypeQuestion extends Model
{
}
class Question extends Model
{
public function ticket_type(){
return $this->belongsToMany('App\TicketType', 'ticket_type_questions')
->withPivot('required');
}
}
Таблица взаимосвязей релевантных для вопроса:
1 to many between congress and ticket types (a congress can have many ticket types)
1 to many between ticket types and ticket_type_questions (a ticket type can have many custom questions)
1 to many between questions and ticket_type_questions (a question can be associated with many ticket types)
Таблица ticket_type_questions имеет следующую структуру: id, ticket_type_id, question_id, required
. Обязательный столбец равен 1, если пользовательский вопрос требуется для данного типа заявки, и 0, если не требуется.
