Laravel Many to Many relationship gets partial results - php

Question

I have Course and Category Models with many to many relationship between them. So I created CategoryCourse Model to decompose relationship. Here are my three models:
class CategoryCourse extends Model
{
private $foreignkeys = [
'$category_id','$course_id'
];
public function categories()
{
return $this->belongsToMany('App\Category');
}
public function courses()
{
return $this->belongsToMany('App\Course');
}
}
class Category extends Model
{
protected $title = ['title'];
public function categorycourse()
{
return $this->hasMany('App\CategoryCourse');
}
}
class Course extends Model
{
protected $fillable = [
'title', 'desc'
];
public function categorycourse()
{
return $this->hasMany('App\CategoryCourse');
}
}
In my controller I have method as follows:
public function getCoursesByCategory(Request $request, $id)
{
$id = Hashids::decode($id);
$categories = Category::findOrFail($id[0]);
$courses = $categories->categorycourse()->get();
return view('courses',compact('courses'));
}
I have three tables in database, they are categories, courses and category_courses. My view is displaying results from category_courses but not results from courses. I am learning laravel. Can any one please help? I want to display all courses that belong to a category, in my view.
Here is my view code:
#foreach($courses as $course)
{{$course->title}}
#endforeach

Answer 1

You have to change your code to:
class Category extends Model
{
protected $title = ['title'];
public function courses()
{
return $this->belongsToMany('App\Course', 'category_course', 'category_id', 'course_id');
}
}
The relationship should be in Category only.
And then you call:
$courses = $categories->courses;
