POWhy does my demo app on Heroku only show the "Welcome Aboard" page

copied!<p><strong>Note:</strong> I have spent the morning carefully checking the similar questions on this subject but it has not helped.</p> <p><strong>My Question</strong></p> <p>I am following Michael Hartl's Ruby-on-Rails tutorial. The first demo app runs nicely. It shows "Welcome Aboard" and when I add /users it runs the demo app. I pushed it to Heroku and it runs there but only shows the Welcome Aboard page.Adding /users gets "The page you were looking for doesn't exist.". I did not change any routes. It seems I should be able to view my demo app at this point on Heroku. I'm surprised because the tutorial is very thorough.</p> <p><strong>Further Experiments</strong></p> <p>I deleted <code>public/index.html</code>. And removed it from git and committed it and verified with <code>git status</code>. When I try to open <code>localhost/3000</code> I get "Routing Error" as expected. When I add /users, the demo app works as expected. I did not change routes.rb. I was not instructed to in the tutorial. </p> <p>Now I push to Heroku and open my application there I now get "The page you were looking for doesn't exist." That seems right. The same as if I opened <code>localhost/3000</code> when running locally. But when I add '/users' at Heroku I still get the page error. Do I need to add a route? This is not mentioned in the tutorial (or I overlooked something).</p> <p>Thanks for help for this newbie to Rails.</p> <p><strong>More Info</strong></p> <p>I did add a route to point to <code>users/index</code> which now makes my localhost version open right up to the application without having to manually add <code>users</code> onto the URL. But when fully committed and pushed to heroku I still get a page error.</p> <p>Here is the output from rake routes:</p> <pre><code>~/Documents/demo_app: rake routes users GET /users(.:format) users#index POST /users(.:format) users#create new_user GET /users/new(.:format) users#new edit_user GET /users/:id/edit(.:format) users#edit user GET /users/:id(.:format) users#show PUT /users/:id(.:format) users#update DELETE /users/:id(.:format) users#destroy root users#index </code></pre>
