If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

Lookupable Trait for Laravel eloquent models for quick and efficient table lookups.

Total Downloads License

About the package

When building more complex applications, lookup queries can add up without you even knowing. The lookupable trait will only get the lookup instances once per request and store them in memory. Every next time you want to lookup a lookupable instance of the same Model, the lookup methods will access the in memory stored instances and prevent a query.

Example: You have a lookup table for statuses like pending, draft, published, deleted. You can access these instances multiple times, with only one query per request:

Installation

You can install the package via composer:

Usage

The Lookupable trait can be used only for Eloquent Models

Example table scheme for 'Roles'

id identifier title
1 admin Admin User
2 user System User
3 guest Guest User

Lookupable methods

After this you can lookup instances easily with the following methods:

Single Lookup

Single Lookup which throws an \Illuminate\Database\Eloquent\ModelNotFoundException error when no record could be found

Multiple Lookup

Multiple Lookup which throws an \Illuminate\Database\Eloquent\ModelNotFoundException error when any of the given record could NOT be found

Soft Deleted items

All of the above methods can except a second parameter (bool $withTrashed = false;), to also return with Soft Deleted items.

Note: When trying to use the Soft Deleted items, please make sure your Eloquent Model implements the \Illuminate\Database\Eloquent\SoftDeletes trait.

I don't have an identifier column?

So your database table doesn't contain an identifier column and looks like this Country table for example:

id code title
1 NL Netherlands
2 UK Great Brittain
3 BE Belgium
4 US United States
5 ... ...

No worries, you can define your own lookup column name in your model like so:
