Rails - Sep 2013 - form_for is always posting to "new" despite url: parameter being set

Hi all,

I''m trying to code log in/out and session logic into my first rails
app.
 The session#new resource has no problem showing me the log in page and 
form, but every time I click submit it posts to sessionscontroller#new 
(again) instead of create, despite the fact that I''ve given it the
create
path in the url: parameter:

routes.rb:
  root ''static_pages#homepage''

  match ''/about'',   to:
''static_pages#about'',    via: ''get''
  match ''/signin'',  to: ''sessions#new'',     
via: ''get''
  match ''/signout'', to: ''sessions#destroy'', 
via: ''delete''
  match ''/signup'',  to:
''static_pages#homepage'', via: ''get''

  resources :users
  resources :dashboards
  resources :sessions, only: [:new, :create, :destroy]

 

rake routes:
     sessions POST   /sessions(.:format)            sessions#create
   new_session GET    /sessions/new(.:format)        sessions#new
       session DELETE /sessions/:id(.:format)        sessions#destroy


the app/views/sessions/new.html.rb code

9     <div class="offset4 span4 border-radius">
 20       <form id="sign-in">
 21        <legend>Sign In with your email address and
password</legend>
 22        <%= form_for(:session, url: sessions_path) do |f| %>
 23          <%= f.label :email_address %>
 24          <%= f.text_field :email_address, :placeholder => 
"you@location.            domain"  %>
 25
 26          <%= f.label :password %>
 27          <%= f.password_field :password %>
 28
 29          <%= f.submit "Sign in", :class => "btn
btn-large btn-success"
%>
 30       <%end%>
 31      </form>
 32      <h6>Don''t have an account? <%= link_to "Sign
up!", signup_path
%></h6>
 33     </div>



sessions_controller.rb

class SessionsController < ApplicationController
  def new
  end

  def create
    user = User.where(:email_address => 
params[:session][:email_address].downcase). first()
    if user && user.authenticate(params[:session][:password])
      sign_in user
      redirect_to dashboard_path(user)
    else
      flash.now[:error] = ''Invalid email/password combination''
      render ''new''
    end
  end

  def destroy
  end
end



What happens in the server logs when I click "sign in"

Started GET 
"/signin?utf8=%E2%9C%93&authenticity_token=9LMTkTw1VDYWm%2F0UMzRdxzTm29Bu91g76stVAYu%2BROU%3D&session%5Bemail_address%5D=tester1%40lastname.com&session%5Bpassword%5D=[FILTERED]&commit=Sign+in"
for 107.15.18.100 at 2013-09-26 16:53:27 +0000
Processing by SessionsController#new as HTML
  Parameters: {"utf8"=>"✓", 
"authenticity_token"=>"9LMTkTw1VDYWm/0UMzRdxzTm29Bu91g76stVAYu+ROU=",
"session"=>{"email_address"=>"tester1-rW81g9KcW2ZWk0Htik3J/w@public.gmane.org",
"password"=>"[FILTERED]"},
"commit"=>"Sign in"}
  Rendered sessions/new.html.erb within layouts/application (3.4ms)
Completed 200 OK in 15ms (Views: 14.5ms)



I have stared at this for hours, I have no idea what I''m missing.  Any
help
is appreciated.

Thanks,

Derek

It is not legal html to have nested forms.

And the point of that is that the browser will take apart that illegal page and
make a valid form out of it, ignoring the nested child. Make this into a test
page in your text editor, and view it in a browser.

    <!DOCTYPE html>
    <html>
    <head>
      <meta charset="utf-8" />
      <title>untitled</title>
    </head>
    <body>
    <form action="foo" method="get"
accept-charset="utf-8">
      <form action="bar" method="get"
accept-charset="utf-8">
        <p><input type="text"
value="baz"/></p>
      </form>
      <p><input type="text"
value="boo"/></p>
    </form>
    </body>
    </html>

If you view source, and actually look at the source code, you''ll see
what I typed here. If you view the DOM (what the browser made out of it) you
will see this instead:

    <!DOCTYPE html>
    <html><head>
      <meta charset="utf-8">
      <title>untitled</title>
    </head>
    <body>
    <form action="foo" method="get"
accept-charset="utf-8">
      
        <p><input type="text"
value="baz"></p>
      </form>
      <p><input type="text"
value="boo"></p>
     </body></html>

See how the outer form is all that is left, and the inner form''s
contents have been shifted outside of the outer form entirely? That''s
just what Safari does -- other browsers may put the elements in a slightly
different order -- but you can''t control this. The only way around it
is to code a valid HTML page. Then, if the browsers mess it up, that''s
on them, not you.
