Follwed a Guide at http://guides.rubyonrails.org/getting_started.html.Generated
a scafffold as
rails generate scaffold Post name:string title:string content:text
The content of app/view/posts/
index.html.erb file are as under
<h1>Listing posts</h1>
<table>
<tr>
<th>Name</th>
<th>Title</th>
<th>Content</th>
<th></th>
<th></th>
<th></th>
</tr>
<% @posts.each do |post| %>
<tr>
<td><%= post.name %></td>
<td><%= post.title %></td>
<td><%= post.content %></td>
<td><%= link_to 'Show', post %></td>
<td><%= link_to 'Edit', edit_post_path(post) %></td>
<td><%= link_to 'Destroy', post, :confirm => 'Are you
sure?', :method => :delete %></td>
</tr>
<% end %>
</table>
<br />
<%= link_to 'New Post', new_post_path%>
Now look at following line of code,and
please help me to understand it
1) <% @posts.each do |post| %>
is it will execute when at least one post will be created??)
2) <td><%= post.name %></td>
<td><%= post.title %></td>
<td><%= post.content %></td>
(is it will get a values from database?)
Thanks
