Eloquent Single Table Inheritance
==================================
This is a very simple implementation of single table inheritance for Eloquent (Laravel & Lumen).
There are no attribute restrictions or anything that could be considered robust.
There are other libraries that do those things quite well.
This simply allows you to have a single table that, when fetched, is thrown into
an Eloquent model of your choice, defined by a column in that table
(typically "type", which is the default keyed type column. You can customize this).
For instance, imagine you have the following table (called `people`):
| id | name | sex |
| ---|------|------|
| 1 | Fred | boy |
| 2 | Jill | girl |
... and imagine you had the following classes:
```php
class Person extends StiParent
{
protected $table = 'people';
protected static $stiKey = 'sex';
protected static $stiChildren = [
'boy' => Boy::class,
'girl' => Girl::class,
];
}
class Boy extends Person
{
//
}
class Girl extends Person
{
//
}
```
When you fetch all people, you will get a mix of boys & girls in the collection.
When you fetch just boys, you will get just boys.
When you fetch just girls, you will get just girls.
UNFORTUNATELY
-------------
1. You cannot make your `Person` class abstract.
2. You must specify the table on the parent
3. When creating a `hasMany` association, you must make sure you specify the foreign key. Otherwise, it will try to automatically generate one from the class name.
