How can i create a Laravel API to show ads added by admin based on impression count of users? - sql

Question

I've an admin side in my laravel project where admin can add Ads along with impression and hours. For e.g if i add a add with impression = 2 and hours = 2. So, once the user have viewed this ad for 2 times then user will not be shown that Ad for the next 2 hours.
Here is the structure of admin ads table:
--------------------------------------
id | image |impressions| hours |
1 | image.png| 2 | 6 |
--------------------------------------
And there's ads_impression_log where i store the log of users who have viewed an ad
---------------------------------------------
id | user_id | ad_id | impression_datetime |
1 | 1 | 1 | 2020-07-28 23:22:45 |
---------------------------------------------
How can i create a laravel query so, that i get specific ad impression count and if impression count is within the hours show the user next ad.
This is my first question here. So, please ignore if there's some mistake :)

Answer 1

Ad Model
public function users(){
return $this->belongsToMany(App\Add, 'ads_impression_log', 'ad_id', 'user_id')
->withPivot('impression_datetime');
}
User Model
public function ads(){
return $this->belongsToMany(App\Add, 'ads_impression_log', , 'user_id', 'ad_id')
->withPivot('impression_datetime');
}
Impression count of a given user($user_id) for a given ad.($user_id)
We'll use the collection method filter here.
$user = User::with('ads')->find($user_id);
//
$ads = $user->ads->filter(function($value, $key){
return $value->id === $ad_id;
});
Now you can get the count of those impressions.
$count = $ads->count();
Impressions required for that ad.
$ads->first()->impression;
You can do the comparison accordingly.
And to get the impression_date column from the pivot table you could do the following.
foreach($ads as $adImp){
$adImp->pivot->impression_date;
}
