RE: 1 render definition for many actions (cleaner)

Hi James,

Unfortunately that doesn’t work if you use the

@zombies 

variable in the rendered template, which is why default_render was added as a patch AFAIK. :)

before_filter is called too soon, after_filter is called after an attempt at rendering is made, so default_render is the only option for this as far as I know.

1 render definition for many actions (cleaner)

@arronwashington, you can just call render rather then using instance_eval to overwrite default_render, for example:

before_filter :render_filter, :only => [:zombies, :cool_zombies]

def zombies
  @zombies = Zombie.find(:all)
end

def cool_zombies
  @zombies = Zombie.find(:all, :conditions => { :eats_humans => false, :is_hippie => true })
end

protected

def render_filter
  # without instance_eval or overwriting default_render
  render :template => 'zombies/all'
end

1 render definition for many actions.

Overriding default_render in especially useful when you have many actions that all render the same thing.

before_filter :render_filter, :only => [:zombies, :cool_zombies]

def zombies
  @zombies = Zombie.find(:all)
end

def cool_zombies
  @zombies = Zombie.find(:all, :conditions => { :eats_humans => false, :is_hippie => true })
end

protected

def render_filter
  instance_eval do
    def default_render
      render :template => 'zombies/all'
    end
  end
end

RERE: 1 render definition for many actions (cleaner)

@arronwashington. Ah, so that’s the motivation for using default_render, thanks for clearing that up, thanks :)
