Installation

Install via composer

Upgrade V2 to V3

• ViewAny plicy now checks for a viewAny permission and not list for the viewAny permission check
• Dropped support for php 7.3 & 7.2
• Dropped support for Laravel 6 & 7
• marked execute helper as deprecated
• fixed Model::orWhereNotNullOrEmpty method to do correct query

  Crud Policy Trait

By using the CustomD\LaravelHelpers\Models\Policies\CrudPermissions trait in your model policy alongside Spatie role permissions you can avoid having to write lots of boilerplate methods in your policy file.

Instead of a Policy like this

it would now look as follows:

and it will automatically check for the following permissions which you would have seeded / set up in Spatie's package.

• users.viewAny
• users.view
• users.create
• users.update
• users.delete
• users.forceDelete
• users.restore

Additionally if using the PermissionBasedAccess trait on your model, the following extra ones are taken into account

• users.viewOwn (as long as you own the record)
• users.updateOwn
• users.deleteOwn

If the user_id column is not user_id, set that in the getOwnerKeyColumn method documented below in the Crud Access for Model section.

viewAny, create, restore & forceDelete will use the base versions only, and you would need to customise if needed yourself by setting up the permission or policy method to deal with it based on your business logic. Create and viewAny do not have Ownership within a default policy, and the restore / forceDelete are mainly only an administrative functionality.

Permission naming.

The permission naming will by default use a plural of the model name: ie User becomes users / BlogPost becomes blog_posts

Crud Access Permission Global Trait & Scope for Model

If you use the CustomD\LaravelHelpers\Traits\PermissionBasedAccess trait on your model it will look for the following Spatie permissions by default:

xxx.view, xxx.viewOwn

This works as follows:

• if viewOwn is true, then it will call scopeCanRetrieveOwnRecord scope
• else if view is true, then it will call scopeCanRetrieveAnyRecord scope
• else it will fallback to scopeCannotRetrieveAnyRecord scope

To modify the user column, add this to the model.

to call without the scopes: use the withoutPermissionCheck modifier: eg Model::withoutPermissionCheck()->get()

Helpers

execute - this helper runs an execute action on an action file with dependancy injection on the contructor

If you discover any security related issues, please email instead of using the issue tracker.

String Helpers

isEmail -- usage Str::isEmail('xxx') or str('xxx')->isEmail() -- will return boolean.

Array Helpers

pushBefore - will push one or more items before the specified key, or append to the end of the array if the key does not exist: PushAfter will push one or more items after the specified key

Collection Helpers

pushBefore - will push one or more items before the specified key, or append to the end of the array if the key does not exist: PushAfter will push one or more items after the specified key

DB Macros

Null Or Empty

when dealing with some of our legacy databases we have some columns where the entry is either null or empty and these macros allow you to query this without the double entries:

Case insensitive statments

Enforced Non Nullable Relations (orFail chain)

DB Repositories

use of repositories via extending the CustomD\LaravelHelpers\Repository\BaseRepository abstract example in the UserRepository.stub.php file

Observerable trait (Deprecated)

adding this trait to your models will automatically look for an observer in the app/Observers folder with the convension {model}Observer as the classname,

you can additionally/optionally add

to add a additional ones if

Replace this with

Record or Fake HTTP Calls

The RecordsOrFakesHttpCalls trait will allow you to record or fake http calls in your tests. This is useful for testing external api calls without actually calling them.

Add the trait to your PHPUnit test file, ensure the tests/stubs/ directory exists, and then wrap your test code in a callable:

Date Manipulation

You can set user timezones via the following options:

1. optionally create a migration with:

2. in user model:

Additionally you can set defaults on the timezone via the attributes method or a setter or even in the migration.

3. in your app config file add the user_timezone parameter.

4. add the UserTimeZone middleware to your api middleware list.

You can now access the current requests timezone via config('request.user.timezone')

Date(Carbon) Helpers attached to above:

methods available:

• setUserTimezone(string $timezone) : Static - sets the users timezone (default set by helper)
• getUserTimezone() : string - gets current users timezone
• setSystemTimezone(string $timezone) : Static - sets system timezone (Default app.timezone)
• getSystemTimezone(): string - gets teh current timezone
• toUsersTimezone(): Static - returns carbon instance set to users timezone
• toSystemTimezone(): Static - returns carbon instance set to system timezone
• usersStartOfDay(): Static - returns carbon instance set to start of users day (converts to users timezone => start of day => to systemtime)
• usersEndOfDay(): Static - users end of day
• usersStartOfWeek(): Static
• usersEndOfWeek(): Static
• usersStartOfMonth(): Static
• usersEndOfMonth(): Static
• usersStartOfQuarter(): Static
• usersEndOfQuarter(): Static
• usersStartOfYear(): Static
• usersEndOfYear(): Static
• parseWithTz(string $time): Static - parses the time passed using the users timezone unless the timezone is in the timestamp
• hasISOFormat(string $date): bool - checks if the date is in iso format.

You can also use the CDCarbonDate to create a few different date objects.

Value Objects

Example:

Or using attributes to make advanced objects.

Best practice is to use the make option, which will validate, if you use a public constructor it will not.

These should all be marked as READONLY and FINAL.

The attributes available are:

• ChildValueObject(valueobectclass) - which will make a new valueObject
• CollectableValue(valueobjectclass) - which will convert an array to a coollection of the value objects
• MakeableObject(class, [?$spread = false]) - will look for a make method or else construct if passed an non object - if spread is true will expand the array else will pass the array as a single argument
• MapToCase(('snake|camel|studly')) - for the fromRequest method

Mapping Valueobject from your Request would be as easy as doing one of the following:

As we are using final classes, these are immutable, if you need a cloned copy with edited values you can use the put command to create a new value object: eg:

Larastan Stubs

these are temporary only till implemented by larastan

add to your phpstan.neon.dist file

Filament Plugin

this is only if you want to deal with user timezones for display, else will be in UTC in the Filament panel

simply add to your panelProvider ->plugin(UserTimeZonePlugin::make())
