如何在视图刀片中显示 eloquent 查询？

Question

I am querying a list of staffs from 'itemregistration' table with the eloquent relationship with 'section' table. But I cannot display the information from section table to the view blade.

My controller get the query as follows:

  $itemregistrations = Itemregistration::with('section')->get();

When I check the array with:

 dd($itemregistrations->toArray());  

I get this result:

 0 => array:133 [▼
"ItemRegistrationID" => 1
"RegistrationDate" => "2005-12-01"
"SectionID" => 12
"name" => "A SANTESH"
"section" => array:2 [ …2]
]

The section array should contain 'SectionID' and 'sectionname' fields.

If I check with dd($itemregistration);

it produce

 Collection {#1948 ▼
 #items: array:1125 [▼
 0 => Itemregistration {#1990 ▼
  #primaryKey: "ItemRegistrationID"
  #hidden: array:1 [ …1]
  +timestamps: false
  #connection: "mysql"
  #table: null
  #keyType: "int"
  +incrementing: true
  #with: []
  #withCount: []
  #perPage: 15
  +exists: true
  +wasRecentlyCreated: false
  #attributes: array:133 [ …133]
  #original: array:133 [ …133]
  #changes: []
  #casts: []
  #dates: []
  #dateFormat: null
  #appends: []
  #dispatchesEvents: []
  #observables: []
  #relations: array:1 [ …1]
  #touches: []
  #visible: []
  #fillable: []
  #guarded: array:1 [ …1]

I want to display the result in the blade but failed to fetch the section array value:

 @foreach($itemregistrations as $index => $value)                                                                
    <td>{{ $value->name }}</td>
    <td>{{ $value->section->sectionname }}</td>
 @endforeach 

I also tried:

 @foreach($itemregistrations as $index => $value)                                                                
    <td>{{ $value->name }}</td>
    @foreach($value as $section => $val) 
     <td>{{ $val->sectionname }}</td>
    @endforeach 
 @endforeach 

But also failed. The error appears is "Trying to get property of non-object".

I tried to see the values contained in the collection through this code:

    @foreach ($itemregistrations as $item)
     <tr>
       <td>{{ $item }}</td>
       <td>{{ $item->section }}</td>                             
     </tr>
    @endforeach  

And it shows this value in this format:

{"ItemRegistrationID":1,"name":"A Santesh"{"SectionID":12,"sectionname":"E"}}

If I show the result with this: @foreach ($itemregistrations as $item) {{ $item->name }}
@endforeach

I can get the name list but to get the sectionname with this

    @foreach ($itemregistrations as $item)
     <tr>
       <td>{{ $item->section->sectionname }}</td>                           
     </tr>
    @endforeach 

It shows error "Trying to get property of non-object ". I dont understand why I can't get the section values.

My section model:

  class Section extends Authenticatable
{
protected $table = 'sections';
protected  $primaryKey = 'SectionID';
 /**
 * Get the user that have agama.
 */
public function itemregistrations()
{
    return $this->hasMany('App\Itemregistration', 'SectionID', 'ItemregistrationID');
}

}

Itemregistration model:

  class Itemregistration extends Model 
{
protected  $primaryKey = 'ItemRegistrationID';

/*
 * Get all of the owning models.
 */

public function section()
{
    return $this->belongsTo('App\Section', 'SectionID');

}

How to get display the query with section array values?

Answer 1

You can do with the following code:

@foreach($itemregistrations as $index => $value)
  <td>{{ $value->name }}</td>
  @foreach($value->section as $section) 
    <td>{{ $section->sectionname }}</td>
  @endforeach 
@endforeach 

Answer 2

I assume, that @foreach call toArray() on Collection , so then you should handle your data as named array, so try this:

@foreach($itemregistrations as $index => $value)                                                                
  <td>{{ $value['name'] }}</td>
  @foreach($value['section'] as $section => $val) 
    <td>{{ $val['sectionname'] }}</td>
  @endforeach 
@endforeach 

Answer 3

Thank you for others' help with my question.

I had configured the right syntax to get to the values of sectionname in section array. I don't know why I can't use -> helper to get to the values. I tried the following syntax and it can fetch the values in blade view.

 @foreach ($itemregistrations as $item)
 <tr>
   <td>{{ $item->name }}</td> //also can <td>{{ $item['name'] }}</td>
   <td>{{ $item['section]['sectionname'] }}</td>                             
 </tr>
@endforeach
