Eloquent Relationship for Learning Management System using Laravel - laravel

Question

I have three model for the LMS which are Course, Section and Lesson. So under course there are sections and under sections there are specific lessons. I already got the relationship for Course and Section but my problem is on the lessons.
My Model schema
Courses
ID,
title,
user_id,
cat_id,
Sections
Id,
course_id,
title,
lessons
id,
section_id,
course_id,
user_id,
body_content,
lesson_title
I have tried this code but it doesnt work..
Here is my section model:
class Section extends Model
{
public function course()
{
return $this->belongsTo(Course::class);
}
public function lessons()
{
return $this->hasMany(Lesson::class,'section_id');
}
}
Lesson.php
class Lesson extends Model
{
public function section()
{
return $this->belongsTo(Section::class);
}
}
Course.php
class Course extends Model
{
protected $fillable = ['title', 'image'];
public function user()
{
return $this->belongsTo(User::class);
}
public function sections()
{
return $this->hasMany(Section::class);
}
}
LmsController.php
public function show($id)
{
$course = Course::with('sections')->find($id);
$othercourses = Course::orderby('created_at','desc')->get();
$sections = Section::with('lessons')->find($id);
$previous = Course::where('id', '<', $course->id)->orderBy('id', 'desc')->first();
$next = Course::where('id', '>', $course->id)->first();
$categories = Lmscategory::orderBy('name', 'asc')->get();
return view('users.learning.show', [
'course'=> $course,
'othercourses'=>$othercourses,
'previous'=>$previous,
'next'=>$next,
'categories'=>$categories,
'sections'=>$sections
]);
}
Blade.php
#foreach($course->sections as $section)
<button type="butcon" class="list-group-item list-group-item-action active">
{{$section->title}}
</button>
#foreach($sections->lessons as $lesson)
<div class="list-group">
<button type="button" class="list-group-item list-group-item-action">
<i class="fa fa-check-square-o"> </i>{{$lesson->lesson_title}}
</button>
</div>
#endforeach
#endforeach
I need to come up with this output:
Course Title: ICT Application Software
Section 1: Getting to know function
Lesson 1: Function Wizard
Lesson 2: IF Function
Section 2: Advance formula and functions
Lesson 3: Formula
Lesson 4: Advance Functions

Answer 1

If you need to show lessons of sections you can add something like this in your controller $course = Course::with(['sections', 'sections.lessons'])->find($id);.
Blade
#foreach($course->sections as $section)
<button type="butcon" class="list-group-item list-group-item-action active">
{{$section->title}}
</button>
#foreach($section->lessons as $lesson)
<div class="list-group">
<button type="button" class="list-group-item list-group-item-action">
<i class="fa fa-check-square-o"> </i>{{$lesson->lesson_title}}</button>
</div>
#endforeach
#endforeach
And do dd($course) to see what you got. I think you need that to present like this:
Course Title: ICT Application Software
Section 1: Getting to know function
Lesson 1: Function Wizard
Lesson 2: IF Function
Section 2: Advance formula and functions
Lesson 3: Formula
Lesson 4: Advance Functions
Section.php
public function course(){
return $this->belongsTo(Course::class);
}
public function lessons(){
return $this->hasMany(Lesson::class);
}
Lesson.php
public function section(){
return $this->belongsTo(Section::class, 'section_id');
}
