<%= raw(render_meta_tags(@category)) %>
<%= render_page_title(@category) %>
At controllers/posts_controller.rb
before_filter :find_category
before_filter :prepare_dynamic_page, :only => [:show]
def index
@posts = Post.order('id')
respond_with(@posts)
end
def show
@post = Post.find(params[:id])
respond_with(@post)
end
protected
def find_category
@category = Category.first
