[Rails] View

Basic example

• Put this in list.html.erb

<% if @books.blank? %>
<p>There are not any books currently in the system.</p>
<% else %>
<p>These are the current books in our system</p>

<ul id = "books">
   <% @books.each do |c| %>
   <li><%= link_to c.title, {:action => 'show', :id => c.id} -%></li>
   <% end %>
</ul>

<% end %>
<p><%= link_to "Add new Book", {:action => 'new' }%></p>

• Mostly, you should create a html.erb for most of the actions, meaning that there will be new.html.erb, edit.html.erb, and etc.
• Each html.erb is used by the action in the controller such as new, edit, index, and etc

• Files are mostly inside app/views

erb

• A Rails template

• erb means “embedded ruby”

• <% %> for Ruby code that does not return

• <%= =%> for when you want output
