User Association

Please Im trying to create an application where i can post like twitter, but i was the users name to be posted under their respective posts

My Post_controller looks like this def index     @posts = Post.all(:order => "created_at DESC")     @users = User.find(:all)     #@user_id = current_user.find(params[:id])

    respond_to do |format|       format.html     end   end

  def create     @post = current_user.posts.create(:message => params[:message])     @user.id = current_user.username

the models both have the correct association and tables are having User_id as primary on User table and Foreign on the Post Table, how do i create a method to be a able to have my index view show the post and name.

Not sure I understand exactly, but if you have a post in this_post, say, then the user is this_post.user, so the name will be this_post.user.name

Showing something is a matter of your View. Just use the association, as Colin said, when building the HTML,

I don't understand that, what is @user and why are you trying to set its id to the name of the current user?

I said how to do this already. In your view at some point you have a variable this_post or just post or something. The user created that post will be this_post.user and the name, presumably, is this_post.user.name.

I suggest that you work through some rails tutorials to get a grasp of the basics. railstutorial.org is good and is free to use online. Work right through it doing all the exercises and so on. Also look at the Rails Guides.
