I am a very beginner of using ruby on rails. I am trying to build my first full-stack app but I have an error of
Missing template tweets/index
root to: 'tweets#index'
get 'tweets', to: 'tweets#index'
From the tree view of your text editor, it looks like
index.html.erb isn't inside the
tweets folder. ie. It is on the same level as that of the
tweets folder(outside it).
Move it to the
tweets folder and it should work.
