Laravel - Name instead of ID - laravel

Question

Somehow I can't trace what is wrong with my codes. I'm trying to display a typ_name instead of id, so I defined the following relationship in both type and infrastructure models but I can't able to display the name.
Models codes shown below
type.php
<?php
namespace App\Models;
use Eloquent as Model;
use Illuminate\Database\Eloquent\SoftDeletes;
/**
* Class type
* #package App\Models
* #version January 16, 2020, 4:01 am UTC
*
* #property string typ_name
*/
class type extends Model
{
use SoftDeletes;
public $table = 'types';
protected $dates = ['deleted_at'];
public $fillable = [
'typ_name'
];
public function type()
{
return $this->hasMany('infrastructure');
}
/**
* The attributes that should be casted to native types.
*
* #var array
*/
protected $casts = [
'id' => 'integer',
'typ_name' => 'string'
];
/**
* Validation rules
*
* #var array
*/
public static $rules = [
'typ_name' => 'required'
];
}
infrastructure.php
<?php
namespace App\Models;
use Eloquent as Model;
use Illuminate\Database\Eloquent\SoftDeletes;
/**
* Class infrastructure
* #package App\Models
* #version January 23, 2020, 1:44 am UTC
*
* #property string inf_name
* #property integer inf_height
* #property integer inf_width
* #property integer typ_id
* #property integer island_id
* #property integer engnr_id
* #property integer designer_id
* #property integer foreman_id
* #property string start_date
* #property string cmplt_date
* #property string inf_lifspan
* #property string inf_file
* #property integer inf_lat
* #property integer inf_long
* #property string inf_comment
*/
class infrastructure extends Model
{
use SoftDeletes;
public $table = 'infrastructures';
protected $dates = ['deleted_at'];
public $fillable = [
'inf_name',
'inf_height',
'inf_width',
'inf_length',
'typ_id',
'island_id',
'engnr_id',
'designer_id',
'foreman_id',
'start_date',
'cmplt_date',
'inf_lifspan',
'inf_file',
'inf_lat',
'inf_long',
'inf_comment'
];
/**
* Get the type record associated with the Infrastructure.
*/
public function type()
{
return $this->belongsTo('type', 'typ_id', 'id');
}
/**
* The attributes that should be casted to native types.
*
* #var array
*/
protected $casts = [
'id' => 'integer',
'inf_name' => 'string',
'inf_height' => 'integer',
'inf_width' => 'integer',
'inf_length' => 'integer',
'typ_id' => 'integer',
'island_id' => 'integer',
'engnr_id' => 'integer',
'designer_id' => 'integer',
'foreman_id' => 'integer',
'start_date' => 'date',
'cmplt_date' => 'date',
'inf_lifspan' => 'date',
'inf_lat' => 'double',
'inf_long' => 'double',
'inf_comment' => 'string'
];
/**
* Validation rules
*
* #var array
*/
public static $rules = [
'inf_name' => 'required',
'inf_height' => 'required',
'inf_width' => 'required',
'inf_length' => 'required',
'typ_id' => 'required',
'island_id' => 'required',
'engnr_id' => 'required',
'designer_id' => 'required',
'foreman_id' => 'required',
'start_date' => 'required',
'cmplt_date' => 'required',
'inf_lifspan' => 'required',
'inf_file' => 'required',
'inf_lat' => 'required',
'inf_long' => 'required',
'inf_comment' => 'required'
];
}
infrastructureController.php
public function show($id)
{
$infrastructure = $this->infrastructureRepository->find($id);
if (empty($infrastructure)) {
Flash::error('Infrastructure not found');
return redirect(route('infrastructures.index'));
}
return view('infrastructures.show')->with('infrastructure', $infrastructure);
}
In my blade.php
<!-- Typ Id Field -->
<div class="form-group">
{!! Form::label('typ_id', 'Type:') !!}
{{ $infrastructure->type->typ_name }}
</div>

Answer 1

I think you defined your relation wrong in your infrastructure.php.
Should be
public function type()
{
return $this->belongsTo(type::class, 'typ_id');
}
typ_id being your foreign key in your infrastructures (?) table
Also, don't forget to adjust your type.php
public function type()
{
return $this->hasMany(infrastructure::class);
}
