Pretty good tutorial, I’m used to Ruby but I’m starting in Rails and this is really a must for starters, it takes you all the way and (i did) let’s you add more things on the go. Some of the code is missing in all tutorials though, makes it hard to follow and sometimes is not easy to figure it out yourself.

Wow this is a great tutorial, thanks.

One thing though, i noticed i can add the same friend twice. I want to make it so when i go to add friends if a friendship exists then it doesn’t display the friend when i go to find new friends or when i click the add friend it flash[:notice] = “that user is already your friend”. Im assuming this would probably go in the controller but i dont know how to check if a friendship exists.

nevermind found it here

http://github.com/overture8/Twitter-Blog-Demo/blob/master/app/views/users/show.html.erb

you need to create /users/show.html.erb file and code is:

Username:

Friends

– :delete %>
