In almost every project I need to setup some sort of login, and usually it requires group access to certain data depending on different criteria.

For example I may have groups Admin+Member and I want Members to only be able to see other Users Profiles if the other Profile is active.

I would like to document several speedy ways I have of working with HABTM data.

The code includes: HABTM Select, HABTM Checkbox, HABTM Text Add, HABTM TextArea Edit.
