Approve new Model data before it is persisted

License: MIT License

Latest Version on Packagist GitHub Tests Action Status Total Downloads Packagist PHP Version Laravel Version

Approval is a Laravel package that provides a simple way to approve new Model data before it is persisted.

Installation

You can install the package via composer:

composer require cjmellor/approval

You can publish and run the migrations with:

php artisan vendor:publish --tag="approval-migrations"
php artisan migrate

You can publish the config file with:

php artisan vendor:publish --tag="approval-config"

This is the contents of the published config file:

return [
    'approval' => [
        /**
         * The approval polymorphic pivot name
         *
         * Default: 'approvalable'
         */
        'approval_pivot' => 'approvalable',
    ],
];

The config allows you to change the polymorphic pivot name. It should end with able though.

Usage

The package utilises Enums, so both PHP 8.1 and Laravel 9 must be used.

Note This package does not approve/deny the data for you, it just stores the new/amended data into the database. It is up to you to decide how you implement a function to approve or deny the Model.

Add the MustBeApproved trait to your Model and now the data will be stored in an approvals table, ready for you to approve or deny.

For example, you add it to a Post Model and each time a Post is created or updated, all the dirty data will be stored in the database as JSON for you to do something with it.

<?php

use Cjmellor\Approval\Concerns\MustBeApproved;

class Post extends Model
{
    use MustBeApproved;

    // ...
}

All Models using the Trait will now be stored in a new table -- approvals. This is a polymorphic relationship.

Here is some info about the columns in the approvals table:

approvalable_type => The class name of the Model that the approval is for

approvalable_id => The ID of the Model that the approval is for

state => The state of the approval. This uses an Enum class. This column is cast to an ApprovalStatus Enum class

new_data => All the fields created or updated in the Model. This is a JSON column. This column is cast to the AsArrayObject Cast

original_data => All the fields in the Model before they were updated. This is a JSON column. This column is cast to the AsArrayObject Cast

If you want to check if the Model data will be bypassed, use the isApprovalBypassed method.

return $model->isApprovalBypassed();

Scopes

The package comes with some helper methods for the Builder, utilising a custom scope - ApprovalStateScope

By default, all queries to the approvals table will return all the Models' no matter the state.

There are three methods to help you retrieve the state of the Approval.

<?php

use App\Models\Approval;

Approval::approved()->get();
Approval::rejected()->get();
Approval::pending()->count();

You can also set a state for an approval:

<?php

use App\Models\Approval;

Approval::where('id', 1)->approve();
Approval::where('id', 2)->reject();
Approval::where('id', 3)->postpone();

In the event you need to reset a state, you can use the withAnyState helper.

Helpers

Conditional helper methods are used, so you can set the state of an Approval when a condition is met.

$approval->approveIf(true);
$approval->rejectIf(false);
$approval->postponeIf(true);

$approval->approveUnless(false);
$approval->rejectUnless(true);
$approval->postponeUnless(false);

Events

Once a Model's state has been changed, an event will be fired.

ModelApproved::class
ModelPostponed::class
ModelRejected::class

Persisting data

By default, once you approve a Model, it will be inserted into the database.

If you don't want to persist to the database on approval, set a false flag on the approve method.

Approval::find(1)->approve(persist: false);

Disable Approvals

If you don't want Model data to be approved, you can bypass it with the withoutApproval method.

$model->withoutApproval()->update(['title' => 'Some Title']);
