How to get images that are liked by a certain user? - php

Question

I'm trying to create a variable that contains the last 7 images that have been liked by a user with certain id so I can pass that variable to my view. I believe I have to use whereHas() but so far nothing I've tried work so it's probable I might be doing it wrong.
The tables I have are:
Table: Votes
Columns: id, user_id, image_id, vote
Table: Users
Columns: id, username, password
Table: Images
Columns: id, name, user_id, path
In the votes table, if the vote value is 1, it is a like and of it is 0, it is a dislike.
I have models for the 3 tables like this:
Image
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Image extends Model
{
public function user(){
return $this->belongsTo('App\User');
}
public function votes(){
return $this->hasMany('App\Vote');
}
}
User:
<?php
namespace App;
use Illuminate\Contracts\Auth\Authenticatable;
use Illuminate\Database\Eloquent\Model;
class User extends Model implements Authenticatable
{
use \Illuminate\Auth\Authenticatable;
public function images(){
return $this->hasMany('App\Image');
}
public function votes(){
return $this->hasMany('App\Vote');
}
}
Vote:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Vote extends Model
{
public function images(){
return $this->belongsTo('App\Images');
}
}
I was able to figure something close to what I have in mind:
$likedImages = Image::where('parent_id', NULL)->whereHas('votes', function($q) use ($vote) {
return $q->where('vote', $vote);
})->orderBy('created_at', 'desc')->limit(7)->get();
Unfortunately, this gets liked images by everyone and not just the specific user.

Answer 1

Normally whereHas() will do the trick, if you want the images that has been voted you do something like
Image::whereHas('votes',function($votes) {
//if you want to get only votes with 1 you do
$votes->where('vote',1);
})
//if you want to get the latest 7 images you order them and take 7
->orderBy('id','DESC')
->take(7)
->get();
That will get you all the images that has a votes row, If that fails, maybe your relationships are not set properly.

Answer 2

You need to use the Vote model, and fetch the recent 7 votes where the like value is 1 and LEFT JOIN the images table.
I am not an ORM specialist but...
An untested example:
$votes = Vote::where([
["user_id", "=", $userId],
["vote", "=", 1]])->leftJoin("images", "user_id", "=", "images.user_id")->latest()->take(7);
Again, this is untested, but I gave you the idea.
