Trying to finish ASSOCIATIONS btwn user/article

Still not sure... figured out way to do:
@user = User.find(params[:id])
@article = @user.articles.create(article_params)
in Articles#create to add the USER_ID info automatically to DB on save,
but needed to nest resources in routes.rb file to do, which screwed up
the URLS...

may have to do specialized tweak on routes to make it work out right.
