Dashboard: Friends

[josephbudina]

As an authenticated user,
I see a section for friends,
In this section, there should be a text field to enter a friend's email and a button to "Add Friend"

Scenarios:

1. If I have not added any friends there should be a message. "You currently have no friends".

2. If I have added friends, I should see a list of all my friends.

Details: Users should be able to add a friend by their email address, as long as, the friend is a user of our application and exists in our database.

Example:
Bugs Bunny and Lola Bunny are users of our application, but Daffy Duck is not.

1. When Bugs Bunny enters lola_bunny@gmail.com to add friend it will be successful and Lola should show up as Bugs Bunny's friend.
2. When Bugs Bunny enters daffy_duck@gmail.com to add friend it should give an error message that the user does not exist.

Tips: You'll want to research self-referential has_many through. Here is a good starting point to understand the concept. You will probably need to do more googling but that's part of the fun ;)
