Eloquent Temporary Tags
Auto-expiring tags with additional payload data on any eloquent model.
Built with ❤️ for every smart Laravel developer
Installation:
composer require imanghafoori/laravel-temp-tag
Then you can publish and migrate to create the needed tags table
php artisan vendor:publish
php artisan migrateSample Application in laravel 8:
https://github.com/imanghafoori1/laravel-tasks
In this Daily Task app, you can mark your tasks as complete,failed,ignored and etc but they rollback back to the default state at the end of the day, so you can re-mark them for tomorrow.
Use cases:
-
You want to ban a user, but only for a week.
-
You want to give someone VIP access, but only for a month.
-
Comments approval by admin.
-
You want to put a product in a slider until the weekend.
-
Storing each user preferences, can be done by attaching a 'settings' tag and the preferences as payload.
-
Storing users likes and dislikes on any model.
-
Scheduling models to be published in the future.
-
Coupon code for specific products on specific periods.
Then you put a temporary tag on them and check to see if the model has the tag.
Tag Payload:
You can also store some additional json data, for example why the user got banned, or who banned the user, or a slug or a translation of the title.
This is done by passing the third argument as an array to the ->tagIt(...) method
Keynotes:
-
Tags can also be permanent.
-
We do not touch your existing tables in migrations.
-
You can put tag on any eloquent model or any other object with
getKeyandgetTablemethods on it.
Example:
1- Tag a user until tomorrow
$user = User::find(1);
$tomorrow = Carbon::now()->addDay();
$note = ['reason' => 'You were nasty!']; // You can optionally store additional data in a json column.
tempTags($user)->tagIt('banned', $tomorrow, $note);
tempTags($user)->tagIt('banned'); // will never expire2- After an hour the tag is still active, so:
$user = User::find(1);
$tagObj = tempTags($user)->getActiveTag('banned'); // <--- Uses cache behind the scenes
if (! is_null($tagObj)) {
$tagObj->isActive(); // true
$tagObj->isPermanent(); // false
$tagObj->title === 'banned'; // true
$tagObj->payload; // ['reason' => 'You were nasty!']
$tagObj->expiresAt(); // Carbon instance
}3- After a week, the tag gets expired so:
$user = User::find(1);
$tagObj = tempTags($user)->getTag('banned'); // <--- fetches the tag regardless of its expire date.
if (! is_null($tagObj)) {
$tagObj->isActive(); // false
$tagObj->isPermanent(); // false
$tagObj->title === 'banned'; // true
$tagObj->expiresAt(); // Carbon instance
}Getting payload data:
There are 2 ways to get payload data :
You can use getPayload method
$tagObj->getPayload('reason'); // 'You were nasty!'
$tagObj->getPayload(); // ['reason' => 'You were nasty!']
$tagObj->getPayload('missing_key'); // nullor You can act like eloquent attributes :
$tagObj->reason; // 'You were nasty!'
$tagObj->payload; // ['reason' => 'You were nasty!']
$tagObj->missing_key; // nullDeleting tags:
$user = User::find(1);
tempTags($user)->unTag('banned'); // single string
tempTags($user)->unTag('bann*'); // using a wildcard
tempTags($user)->unTag(['banned', 'man']); // an array of tags to delete
tempTags($user)->deleteExpiredTags(); // all the expired tags, bye bye.Note: You can also use * wildcard which matcher 0 or more characters (just like % in sql)
Note: These fire "deleting" and "deleted" eloquent events for each one of them.
Expire the tag with title of "banned" right now:
tempTags($user)->expireNow('banned'); // updates the value of expire_at to now() and deletes from cacheThese methods just do what they say:
$actives = tempTags($user)->getAllActiveTags(); // A collect of "TempTag" model objects.
$expired = tempTags($user)->getAllExpiredTags();
$all = tempTags($user)->getAllTags();Fetch only tagged models:
Let's say you have a slider for your Product model and you want to show only those records which are tagged with 'slider'.
First you have to put Imanghafoori\Tags\Traits\hasTempTags trait on the Product model.
class Product extends Model
{
use hasTempTags;
...
}Now you can perform these queries:
Product::hasActiveTags('slider')->where(...)->get();
// Only if the tag of model is expired and it has the specified title.
Product::hasExpiredTags('slider')->where(...)->get();
// To fetch regardless of expiration date of tags, only the title matters.
Product::hasTags('slider')->where(...)->get();Note: If you pass an array of tags it acts like a whereIn(), so if the row has one of tags if will be selected.
If you want to find products which will be active until tomorrow, you can use hasActiveTagsAt, or hasNotActiveTagsAt as illustrated below:
Product::hasActiveTagsAt('slider', now()->addDay())->where(...)->get();
Product::hasNotActiveTagsAt('slider', now()->addDay())->where(...)->get();Example:
When you want to send a notification to users, just 24 hours before their VIP account gets finished, so that they can charge.
User::hasActiveTag('VIP')
->hasNotActiveTagsAt('VIP', now()->addDay())
->get();Absence of tags:
Product::hasNotActiveTags('slider')->where(...)->get();
Product::hasNotExpiredTags('slider')->where(...)->get();
Product::hasNotTags('slider')->where(...)->get();Example:
When you want your article to be published in the future, go can tag your articles with a custom tag title like: "hidden" And fetch them like this:
$articles = Article::hasNotActiveTags('hidden')->where(...)->get();So, as long as the 'hidden' tag is active the article does not show on the list and when the tag gets expired the article goes live.
Filtering based on payload:
$product1 = Product::find(1);
$product2 = Product::find(1);
tempTags($product1)->tagIt('status', $tomorrow, ['value' => 'sold_out']);
tempTags($product2)->tagIt('status', $tomorrow, ['value' => 'sold_out']);
// now we have tagged these two rows we can fetch them later on with the below query
...
Product::hasActiveTags('status', ['value' => 'sold_out'])->where(...)->get();The above example gives you the products with active status tag which have also payload data with the specified key and value.
Note: You can also use * wildcard which matcher 0 or more characters (just like % in sql):
Product::hasActiveTags('stat*', ['value' => 'sold_out'])->where(...)->get();Advanced Usage:
Each and every has...Tag method also has a twin orHas...Tag so you can put multiple conditions in the query.
Remember that they both should reside in a ->where(function ($q) { beside one another.
Post::where('user_id', 12)->where(function ($q) {
$q->hasActiveTags('status', ['value' => 'active'])
->orHasActiveTags('status', ['value' => 'promoted']);
})->get();Auto-delete Expired tags:
In order to save disk space and have faster db queries you may want to delete the expired tags.
After you have performed the basic installation you can start using the tag:delete-expired command. In most cases you'll want to schedule this command so you don't have to manually run it everytime you need to delete expired tags.
// app/Console/Kernel.php
protected function schedule(Schedule $schedule)
{
// Will run: php artisan tag:delete-expired
$schedule->command( 'tag:delete-expired' )->everyDay();
