Generate multiple objects for variants based on key field value

[viperx77]

I'm stumped on how to accomplish this:

I have a fixed number of keys and depending on the key value I need to generate different values. I also need to reference a parent object that was generated.

An example may help. I have a table that stores multiple configurations per user:

+--------+------+--------+
| userId | key  |  value |
+--------+------+--------+
| 1      | color | blue  |
| 1      | size  | large |
| 2      | color | red   |
| 2      | size  | small |
+--------+------+--------+

So I need 2 rows per user with the keys 'color' and 'size'

Is this use case supported?
