Overview

Index as Blog

Render your index page as a set of posts. The post has two main options: title and body.

index :as => :blog do
  title :my_title # Calls #my_title on each resource
  body  :my_body  # Calls #my_body on each resource
end

Post Title

The title is the content that will be rendered within a link to the resource. There are two main ways to set the content for the title

First, you can pass in a method to be called on your resource. For example:

index :as => :blog do
  title :a_method_to_call
end

This will result in the title of the post being the return value of Resource#a_method_to_call

Second, you can pass a block to the tile option which will then be used as the contents fo the title. The resource being rendered is passed in to the block. For Example:

index :as => :blog do
  title do |post|
    span post.title, :class => 'title'
    span post.created_at, :class => 'created_at'
  end
end

Post Body

The body is rendered underneath the title of each post. The same two style of options work as the Post Title above.

Call a method on the resource as the body:

index :as => :blog do
  title :my_title
  body :my_body # Return value of #my_body will be the body
end

Or, render a block as the body:

index :as => :blog do
  title :my_title
  body do |post|
    div truncate(post.title)
    div :class => 'meta' do
      span "Post in #{post.categories.join(', ')}"
    end
  end
end
