User Model Permissions / Roles and Approving Ticket Models which creates a Transaction Model

[Greg H]

I have a User Model.

I have a Ticket Model.

( I think I will need a Role Model )?

( I think I will need a Transaction Model )?

-----------------------------------------------------------------------

-----I'm trying to create a Approval Ticket system:------

-----------------------------------------------------------------------

- A User can have a Role which gives specific permissions (i.e. Creating a Ticket Object ) or ( Approving / Denying a Ticket Object).

- The Ticket will be created by a form, which copies the data to the Ticket Table Database.

- Depending on the Ticket being Approved/Denied, it will become a Transaction Object (which will copy all the data from the Ticket Object).

- I think Ticket to Transaction will be a 1 to 1 Association.

-----------------------------------------------------------------------

-----My Questions:------

-----------------------------------------------------------------------

1) How should I implement Roles/Permissions to a User Object? Will I need something like a 1 to 1 Association? (1 User -> 1 Role). How would this look in code?

2) How can I create a Transaction Object from a Ticket Object depending on Approval from a specific User Role? I'm super confused on how I can do this..

Thanks for any help!
