Laravel 5.2 QueryException in Connection.php line 669 - php

Question

i'm developing an API but when I create the relations (Many to Many) and want to show in the index function I'm getting an error QueryException in Connection.php line 669 The error says:
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'CTL_Tags.id' in 'on clause' (SQL: select `CTL_Tags`.*, `CTL_Resource_has_Tags`.`idResource` as `pivot_idResource`, `CTL_Resource_has_Tags`.`idTag` as `pivot_idTag` from `CTL_Tags` inner join `CTL_Resource_has_Tags` on `CTL_Tags`.`id` = `CTL_Resource_has_Tags`.`idTag` where `CTL_Resource_has_Tags`.`idResource` is null)
I believe my error is in my model because it's looking for id in CTL_Tags table when my id name in that table is idTag.
This is my CTL_Resource model
<?php
namespace Knotion;
use Illuminate\Database\Eloquent\Model;
class CTL_Resource extends Model {
public $timestamps = false;
protected $table = "CTL_Resource";
protected $hidden = [
'coachVisibility', 'thumbnail', 'tags', 'relatedTo',
'studentVisibility', 'isHTML','studentIndex', 'coachIndex',
'isURL', 'source', 'path', 'status', 'updateTime', 'isfolder',
'parentResource', 'idModifierUser'
];
protected $fillable = ['idResourceType','productionKey', 'tags', 'idCreatorUser', 'idModifierUser', 'idCreationCountry', 'title', 'description', 'URL', 'fileName', 'extension', 'quicktag', 'minimumAge', 'maximumAge', 'productionKey'];
public function creatorUser() {
return $this->belongsTo('Knotion\OPR_User', 'idCreatorUser');
}
public function creationCountry() {
return $this->belongsTo('Knotion\CTL_Country', 'idCreationCountry');
}
public function resourceType() {
return $this->belongsTo('Knotion\CTL_ResourceType', 'idResourceType');
}
public function quickTags() {
return $this->belongsToMany('Knotion\CTL_QuickTag', 'CTL_Resource_has_QuickTags', 'idResource', 'idQuickTag');
}
public function tags() {
return $this->belongsToMany('Knotion\CTL_Tag','CTL_Resource_has_Tags', 'idResource', 'idTag');
}
public function relatedTo() {
return $this->belongsToMany('Knotion\CTL_RelatedTo', 'CTL_Resource_has_RelatedTo', 'idResource', 'idRelatedTo');
}
}
and I just will show you the code of one of the relations
<?php
namespace Knotion;
use Illuminate\Database\Eloquent\Model;
class CTL_QuickTag extends Model {
protected $table = "CTL_QuickTags";
protected $fillable = ['name'];
protected $hidden = ['status', 'createTime', 'updateTime'];
public function resources() {
return $this->belongsToMany('Knotion\CTL_Resource', 'CTL_Resource_has_QuickTags', 'idResource', 'idQuickTag');
}
}
and this is my Controller
<?php
namespace Knotion\Http\Controllers;
use Illuminate\Http\Request;
use Knotion\Http\Requests;
use Knotion\Http\Requests\ResourcesRequest;
use Knotion\CTL_Resource;
use Knotion\CTL_Tag;
use Knotion\CTL_QuickTag;
use Knotion\CTL_RelatedTo;
use Knotion\CTL_ResourceType;
class ResourcesController extends Controller {
public function index(Request $request) {
$resources = CTL_Resource::paginate(10);
$resources->each(function($resources) {
$resources->tags;
$resources->quickTags;
$resources->relatedTo;
});
return response()->json(
$resources
);
I'll be so grateful who anyone can help me. Thank you so much.

Try to define
$primaryKey
in your model , with the correct column name
