# We want vienna to render our Product#show view...

class ProductController < ApplicationController
  def show
    @product = Product.find(...)
    render :vienna => @product
  end
end

# The `vienna` renderer will look for a view (Vienna::View) subclass that
# is named ShowProductView. The `@product` ivar will be set in that view.
# We then render the views/product/show.erb file in the context of our
# ShowProductView

class ShowProductView < Vienna::View
  def nicer_title
    @product.title + " is really awesome!"
  end
end

# show.erb:
#
# <h1><%= nicer_title %></h1>

# Now, the awesome bit! When our html page loads, we will have an instance of
# ShowProductView running on the client, with the @product ivar already setup!
# So, we can then just use the #after_render hook to do some stuff.

class ShowProductView < Vienna::View
  def nicer_title
    @product.title + " is really awesome!"
  end

  def after_render
    @element.on(:click, '.title') do |evt|
      alert "did you like the title? #{nicer_title}"
    end
  end
end

# ALSO, our events will be setup as well :)

class ShowProductView < Vienna::View
  def nicer_title
    @product.title + " is really awesome!"
  end

  on :click, '.title' do |evt|
    alert "did you like the title? #{nicer_title}"
  end
