Laravel, cant' get property of colletion - php

Question

I have Collection form my Form obj, and iam trying to get all pages belongs to that form,
when I do $survey = Forms::find(68)->with('pages')->get(); Iam getting this:
Illuminate\Database\Eloquent\Collection {#522 ▼
#items: array:18 [▼
0 => App\Models\Forms {#562 ▼
#table: "forms"
#fillable: array:4 [▶]
#connection: "mysql"
#primaryKey: "id"
#keyType: "int"
+incrementing: true
#with: []
#withCount: []
#perPage: 15
+exists: true
+wasRecentlyCreated: false
#attributes: array:9 [▶]
#original: array:9 [▶]
#changes: []
#casts: []
#dates: []
#dateFormat: null
#appends: []
#dispatchesEvents: []
#observables: []
#relations: array:1 [▼
"pages" => Illuminate\Database\Eloquent\Collection {#596 ▼
#items: array:5 [▼
0 => App\Models\Pages {#628 ▶}
1 => App\Models\Pages {#632 ▶}
2 => App\Models\Pages {#633 ▶}
3 => App\Models\Pages {#634 ▶}
4 => App\Models\Pages {#635 ▶}
]
}
]
#touches: []
+timestamps: true
#hidden: []
#visible: []
#guarded: array:1 [▶]
}
]
}
but can't get property of relations, when I do $form->pages Iam getting null
Its works fine for other property like questions (same relations)
here is my model:
class Forms extends Model
{
protected $table = "forms";
protected $fillable = array('name', 'description', 'status', 'token');
public function pages()
{
return $this->hasMany('App\Models\Pages');
}
public function questions()
{
return $this->hasMany('App\Models\Question');
}
}
class Pages extends Model
{
protected $table = "pages";
public $timestamps = false;
protected $fillable = array('name', 'description' ,'priority', 'token');
public function form()
{
return $this->belongsTo('App\Models\Forms');
}
}
and finally, method where Iam trying to get results:
public function index()
{
$survey = Forms::with('pages')->find(68);//Did update regarding to sugestion
dd($survey);
return view("pages.surveys", compact('survey'));
}
Thanks for any help.

Answer 1

I think you should reverse the order of the with() and find() functions.
$survey = Forms::with('pages')->find(68);
Note that find() actually executes the query, therefore you don't have to use get() again. As a rule of thumb: if you need to get only one result out of your query you should use first() or find() (the latter could also be used to retrieve collections), otherwise use all() or get() to fetch a collection of results.

Answer 2

$form = Forms::find(68);
dd($form->pages);
OR
$form = Form::find(68)->pages->get(); //It will return all the pages having relation
try this, It will first find form having id '68' then as per relation given it will fetch the records

Answer 3

Seems almost of your codes are okay. This might be a problem only with your foreign key. In your pages relationship in your forms, laravel will expect a foreign key in your pages table namely 'form_id' or 'forms_id' since you are not passing a second argument in your pages relationship. Make sure that in your pages migration your foreign key is set to to form_id also

when i do dd($survey);
