Creation of duplicate model/database entities

[dcbartlett]

When creating an entity for database consumption, i noticed that you can specify :id on a create call.

E.G. ( http://localhost:1337/user/create/ )
E.G. ( http://localhost:1337/user/create/1?username=someone )
E.G. ( http://localhost:1337/user/create/1?username=someone_else )

This will in fact create 3 different entries...
There needs to be an error thrown stating that id is already in use, or error stating that "update" should be used to make changes to the entity.

Good one- I think there are two problems here:

1. this should never be allowed at the model level, since the uniqueness constraint / PK should be enforced
2. the scaffold should give a helpful error message, as you just pointed out

On second thought, this needs to be looked at further as this was a fix in controller scaffolding, and not at the model level.
