Laravel hasMany relation count number of likes and comments on post - php

Question

The code:
$posts = Jumpsite::find($jid)
->posts()
->with('comments')
->with('likes')
->with('number_of_comments')
->with('number_of_likes')
->where('reply_to', 0)
->orderBy('pid', 'DESC')
->paginate(10);
Each post has a comment and likes. I only display a few of the comments initially to avoid large loads. But I want to show how many the total comments and likes for each post. How do I do this?
Model code:
public function likes()
{
return $this->hasMany('Like', 'pid', 'pid');
}
public function comments()
{
return $this->hasMany('Post', 'reply_to', 'pid')->with('likes')->take(4);
}
public function number_of_likes()
{
return $this->hasMany('Like', 'pid', 'pid')->count();
}
Note:
This is an API. All will be returned as JSON.
update
The return
Post
author_id
message
Comments(recent 4)
user_id
message
post_date
Number_of_likes
Likes
user_id
Number_of_total_comments
Number_of_total_likes
update
How I return the data
$posts = $posts->toArray();
$posts = $posts['data'];
return Response::json(array(
'data' => $posts
));
Just by using that I get all the data i want in the json. But I also want to add the total counts.
update
protected $appends = array('total_likes');
public function getTotalLikesAttribute()
{
return $this->hasMany('Like')->whereUserId($this->uid)->wherePostId($this->pid)->count();
}
but getting the error:
Unknown column 'likes.post_id'
error
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'likes.post_id' in 'where clause' (SQL: select count(*) as aggregate from `likes` where `likes`.`deleted_at` is null and `likes`.`post_id` = 4 and `pid` = 4 and `uid` = 1)

Answer 1

You can use that following code for counting relation model result.
$posts = App\Post::withCount('comments')->get(); foreach ($posts as $post) { echo $post->comments_count; }
And also set condition with count like this
$posts = Post::withCount(['votes', 'comments' => function ($query) { $query->where('content', 'like', 'foo%'); }])->get();

Answer 2

In your model place the following accessors:
Count total Likes:
public function getTotalLikesAttribute()
{
return $this->hasMany('Like')->whereUserId($this->author_id)->count();
}
Count total comments:
From your description, i can see, you have retrieving the number of posts as comments
public function getTotalCommentsAttribute()
{
return $this->hasMany('Post')->whereUserId($this->author_id)->count();
}
Now, from your controller:
$post = Jumpsite::find($jid);
// total comments
var_dump( $post->total_comments );
// total Likes
var_dump( $post->total_likes );

Count comments for all blog posts in laravel
Step 1: Place this code inside your ‘Post’ model.
// Get the comments for the blog post.
public function comments()
{
return $this->hasMany('App\Comment');
}
Step 2: Place this code inside your ‘PostController’ controller.
$posts= Post::all();
return view('home')->with('posts', $posts);
Step 3: Then count comments for all posts using the below code.
#foreach($posts as $row)
{{$row->comments->count()}}
#endforeach

Just single change to get results of the count
In relation
public function getTotalLikesAttribute(){
return $this->hasMany('Like')->where('author_id',$this->author_id)->count();
}
In the view
$post->getTotalLikesAttribute()
