Add feature to change value of a Foreign key using Eloquent model.

[imrealashu]

For example:

table1
id = 1 (PK)
value = 'Something'

table2
id = 2
table1_id = 1
another_field='something else'

After Indexing table2 result will be

id=2
table1_id='something'
another_field='something else'

In this example arise problem:
what field from table1 to add to index if table1 have other fields, besides "value" field?

Therefore for all related fields use indexing for "dynamic fields" (see in readme). For example:

1. In config.php for model of table2 add following option:

        'optional_attributes' => true

1. Add this accessor in model of table2

        public function getOptionalAttributesAttribute()
        {
                return [
                        'table1_id' => "something",
                ];
        }
