Question

I have a lot of actions that receives params via method arguments:

class App < E
  map '/'

  def read page
    @page = page
    # etc.
    render
  end

  def profile user
    @user = user
    # etc.
    render
  end
end

How do i access page, user etc. in templates without assign them to instance variables?

Answer 1

You have at least 2 options here.

Most straightforward one is to use action_params:

def read page
  # use action_params[:page] in templates
end

Please note this works only with Ruby 1.9

In Ruby 1.8 use action_params[0]

Another way is to pass your params as context variables:

def profile user
  render :user => user
  # in templates, user is available as #user getter
  # rather than @user instance variable
end
