title: undefined method in rails
body: <p>I'm new to ruby and started to create my *nd toy app.
  I:</p>
  
  <ol>
  <li>Created controller 'questions'</li>
  <li>Created model 'question'</li>
  <li>Created controller action 'new'</li>
  <li>Added 'New.html.erb' file</li>
  </ol>
  
  <p>in erb file I use <code>form_for</code> helper and and <code>new</code> controller action where I instantiate 
  <code>@question</code> instance variable.
  When I try to run this I get <code>'undefined method: questions_path for #&lt;ActionView::Base:0x5be5e24&gt;'</code> error.
  Below is my new.html.erb:</p>
  
  <pre><code>&lt;%form_for @question do |f| %&gt;
     &lt;%=f.text_field :title %&gt;
  &lt;%end%&gt;    
  </code></pre>
  
  <p>Please advise how to fix this and also help me with aliasing this controller action.
  What I mean is I would like to type <a href="http://mysite/questions/ask" rel="nofollow noreferrer">http://mysite/questions/ask</a>, instead of /questions/create</p>
