Exercise 5

Course Registration System ("Ilmo 2.0") - fourth iteration

You should have these features implemented at the exercise session. You get 1 point for each implemented feature.

1p: User can register to a exercise group
- Implement as you wish, but I would suggest a has_many :through approach.
- Each group shows which users have registered to this group.
- User can only register to one group / course implementation
- You NEED a join table between users and exercise groups (many-to-many relationship)
1p: It is possible to send mail to users who have registered in a exercise group
- Some sort of GUI for sending
- Action Mailer is recommended for this
1p: Newsfeed (facebookish)
- When user has registered in a group, then everybody sees "John is attending Theory of Computation, Autumn 2009" on the front page (newest on top)
- Simple implementation is enough: a "Newsfeed" model or similar, where one row in the database is one event in the system.
- Events when..
  - New user account is created
  - New course is added
  - User registers to a exercise group

You can select three of the following:

1p: Multiple exercise groups
- If course instance is set so that user can register into multiple exercise groups, then it should be possible
- Course instance defines maximum and minimum number of exercise groups for this instance
Administration is protected
- Either: 1p: Administration is protected by boolean field in user
  - If you did not implement any administration at the last iteration, then do one that one page for email sending or something else.
- Or: 2p: Administration is protected by roles
  - User has many roles, where one role would be named as "admin"
  - Or something similar, like a rails plugin
1p: RSS-feed for Newsfeed events
- Atom, RSS any format you like
1p: Profile image uploading
- In user detail edit, it should be possible to upload a profile picture
- http://github.com/technoweenie/attachment_fu or http://github.com/thoughtbot/paperclip or another plugin makes this easy!

It's okay to miss 1 of these, you need to have 4/5 times implemented if you want to have +1credit
