    <p>I am new to Ruby on Rails and have been helped immensely by Michael Hartl's excellent book: Ruby on Rails Tutorial. I have gotten to Chapter 8 and am now on the exercises in that chapter. I am having ( I assume a typical "newbie") problem with exercise 1. In this exercise it is asked "1.Refactor the signin form to use form_tag in place of form_for." I have tried to searching for assistance with this in Stackoverflow, Google, Railscast, and many other "web searches" for two days now and I do not seem to find the assistance that I need to answer this problem. The file I am trying to modify with form_tag is below:</p> <pre><code>&lt;% provide(:title, "Sign in") %&gt; &lt;h1&gt;Sign in&lt;/h1&gt; &lt;div class="row"&gt; &lt;div class="span6 offset3"&gt; &lt;%= form_for(:session, url: sessions_path) do |f| %&gt; &lt;%= f.label :email %&gt; &lt;%= f.text_field :email %&gt; &lt;%= f.label :password %&gt; &lt;%= f.password_field :password %&gt; &lt;%= f.submit "Sign in", class: "btn btn-large btn-primary" %&gt; &lt;% end %&gt; &lt;p&gt;New user? &lt;%= link_to "Sign up now!", signup_path %&gt;&lt;/p&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>I am using Rails 3.2.3 in this application. Can anybody point me in the correct direction? Can anyone help me with this problem? I would be most appreciative.</p> <p>This is the implementation that uses form_tag:</p> <pre><code>&lt;% provide(:title, "Sign in") %&gt; &lt;h1&gt;Sign in&lt;/h1&gt; &lt;div class="row"&gt; &lt;div class="span6 offset3"&gt; &lt;%= form_tag( url: sessions_path ) do %&gt; &lt;%= label_tag :email %&gt; &lt;%= text_field_tag :email %&gt; &lt;%= label_tag :password %&gt; &lt;%= password_field_tag :password %&gt; &lt;%= submit_tag "Sign in", class: "btn btn-large btn-primary" %&gt; &lt;% end %&gt; &lt;p&gt;New user? &lt;%= link_to "Sign up now!", signup_path %&gt;&lt;/p&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>I am using Rspec 2.9.0 and below are the failing tests:</p> <pre><code>describe "signin page" do before { visit signin_path } it { should have_selector('h1', text: 'Sign in') } it { should have_selector('title', text: 'Sign in') } end </code></pre> <p>and</p> <pre><code>describe "with invalid information" do before { click_button "Sign in" } it { should have_selector('title', text: 'Sign in') } it { should have_selector('div.alert.alert-error', text: 'Invalid') } describe "after visiting another page" do before { click_link "Home" } it { should_not have_selector('div.alert.alert-error') } end end </code></pre> <p>and</p> <pre><code>describe "with valid information" do let(:user) { FactoryGirl.create(:user) } before do fill_in "Email", with: user.email fill_in "Password", with: user.password click_button "Sign in" end it { should have_selector('title', text: user.name) } it { should have_link('Profile', href: user_path(user)) } it { should have_link('Sign out', href: signout_path) } it { should_not have_link('Sign in', href: signin_path) } describe "followed by signout" do before { click_link "Sign out" } it { should have_link('Sign in') } end end </code></pre> <p>Here's my routes file:</p> <pre><code>SampleApp::Application.routes.draw do resources :users resources :sessions, only: [:new, :create, :destroy] get "users/new" root to: 'static_pages#home' match '/signup', to: 'users#new' match '/signin', to: 'sessions#new' match '/signout', to: 'sessions#destroy', via: :delete match '/help', to: 'static_pages#help' match '/about', to: 'static_pages#about' match '/contact', to: 'static_pages#contact' end </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
