# Laravel Schedulable [](https://twitter.com/intent/tweet?text=Laravel%20Schedulable:&url=https%3A%2F%2Fgithub.com%2Fneelkanthk%2Flaravel-schedulable)
## Schedule and Unschedule any eloquent model elegantly without cron job.
## Salient Features:
1. __Turn any Eloquent Model into a schedulable__ one by using ```Schedulable``` trait in the model.
2. __Schedule Models to a time in future__ and they will be returned in query results at specified date and time.
3. __Reschedule__ and __Unschedule__ at any time using simple methods.
4. Hook into the model's life cycle via __custom model events__ provided by the package.
5. __Override the default column name__ and use your own custom column name.
__*Some example use cases when this package can be useful:*__
1. A Blog type application which allows bloggers to schedule their post to go public on a future date and time.
2. An E-commerce website where the items in the inventory can be added at any time from the admin panel but they can be scheduled to be made available to the customers at a particular date and time.
## Minimum Requirements
1. Laravel 6.0
2. PHP 7.2
## Installation
```bash
composer require neelkanthk/laravel-schedulable
```
## Usage
#### 1. Create a migration to add ```schedule_at``` column in any table using package's ```scheduleAt();``` method which creates a column with name ```schedule_at```.
#### *NOTE:* If you want to use any other column name then simply use the ```$table->timestamp('column_name');``` method as shown below in examples.
```php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class AddScheduleAtColumnInPosts extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::table('posts', function (Blueprint $table) {
$table->scheduleAt(); //Using default schedule_at column
//or
$table->timestamp('publish_at', 0)->nullable(); //Using custom column name
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::table('posts', function (Blueprint $table) {
$table->dropColumn('schedule_at'); //Using default schedule_at column
//or
$table->dropColumn('publish_at'); //Using custom column name
});
}
}
```
#### 2. Use the ```Neelkanth\Laravel\Schedulable\Traits\Schedulable``` trait in any Model.
#### *NOTE:* If you have used a custom column name in the migration then you have to specify that column in the Model as shown below.
```php
use Illuminate\Database\Eloquent\Model;
use Neelkanth\Laravel\Schedulable\Traits\Schedulable;
class Post extends Model
{
use Schedulable;
const SCHEDULE_AT = "publish_at"; //Specify the custom column name
}
```
## Usage
### 1. Scheduling a model
```php
$scheduleAt = Carbon::now()->addDays(10); //Carbon is just an example. You can pass any object which is implementing DateTimeInterface.
$post = new App\Post();
//Add values to other attributes
$post->scheduleWithoutSaving($scheduleAt); // Modifies the schedule_at attribute and returns the current model object without saving it.
$post->schedule($scheduleAt); //Saves the model in the database and returns boolean true or false
```
### 2. Unscheduling a model
```php
$post = App\Post::find(1);
$post->unscheduleWithoutSaving(); // Modifies the schedule_at attribute and returns the current model object without saving it.
$post->unschedule(); //Saves the model in the database and returns boolean true or false
```
### 3. Events and Observers
The package provides four model events and Observer methods which the developers can use to hook in the model's lifecycle.
The ```schedule()``` method fires two events namely ```scheduling``` before saving the model and ```scheduled``` after saving the model.
The ```unschedule()``` method fires two events namely ```unscheduling``` before saving the model and ```unscheduled``` after saving the model.
The above events can be caught in the Observer class as follows:
```php
namespace App\Observers;
use App\Post;
class PostObserver
{
public function scheduling(Post $post)
{
//
}
public function scheduled(Post $post)
{
//
}
public function unscheduling(Post $post)
{
//
}
public function unscheduled(Post $post)
{
//
}
}
```
### 4. Fetching data using queries
We will assume below posts table as reference to the following examples:
| id | title | created_at | updated_at | schedule_at |
|----|--------------|---------------------|------------|---------------------|
| 1 | Toy Story 1 | 2020-06-01 12:15:00 | NULL | NULL |
| 2 | Toy Story 2 | 2020-08-02 16:10:12 | NULL | 2020-08-10 10:10:00 |
| 3 | Toy Story 3 | 2020-10-10 10:00:10 | NULL | 2021-12-20 00:00:00 |
| 4 | Terminator 2 | 2020-10-11 00:00:00 | NULL | 2021-11-12 15:10:17 |
__For the following examples, Suppose the current timestamp is 2020-10-18 00:00:00.__
#### 1. Default
By default all those models are fetched in which the ```schedule_at``` column is having ```NULL``` value or a timestamp less than or equal to the current timestamp.
So a eloquent query
```php
$posts = App\Post::get();
```
will return Toy Story 1 and Toy Story 2
#### 2. Retrieving scheduled models in addition to the normal.
To retrieve scheduled models in addition to the normal models, use the ```withScheduled()``` method.
```php
$posts = App\Post::withScheduled()->get();
```
The above query will return all the four rows in the above table.
#### 3. Retrieving only scheduled models without normal.
To retrieve only scheduled models use the ```onlyScheduled()``` method.
```php
$posts = App\Post::onlyScheduled()->get();
```
The above query will return Toy Story 3 and Terminator 2.
#### 4. Do not apply any functionality provided by ```Schedulable```.
In some cases you may not want to apply the ```Schedulable``` trait at all. In those cases use the ```withoutGlobalScope()``` method in your query.
```php
use Neelkanth\Laravel\Schedulable\Scopes\SchedulableScope;
$posts = App\Post::withoutGlobalScope(SchedulableScope::class)->get();
```
## A general use case example.
```
// routes/web.php
use Illuminate\Support\Facades\Route;
use Neelkanth\Laravel\Schedulable\Scopes\SchedulableScope;
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
Route::get('/schedule/post', function () {
$post = new App\Post();
$post->title = "My scheduled post";
$scheduleAt = Carbon\Carbon::now()->addDays(10);
$post->schedule($scheduleAt);
return $post; //The scheduled post's ID is 1
});
Route::get('/unschedule/post', function () {
// To unschedule a post you have to fetch the scheduled post first.
// But becuase the Schedulable trait is used in App\Post model it will not a fetch a post whose schedule_at column value is in future.
$post = App\Post::find(1); //This will return null for a scheduled post whose id is 1.
//To retreive a scheduled post you can use any of the two methods given below.
$post = App\Post::withScheduled()->find(1); //1. Using withScheduled() [Recommended]
$post = App\Post::withoutGlobalScope(SchedulableScope::class)->find(1); //2. Using withoutGlobalScope()
$post->unschedule();
});
```
