Passing argument to decorator from controller in Rails using Draper

I couldn't figure out how to pass an argument to a decorator from a controller:

The decorator:

def as_json(options = nil)
  {
   :name => user.name,
   :dob => user.dob
   :created_at => user.created_at,
   :url => user
  }
end

The controller:

format.json { render :json => UserJsonDecorator.new(@user)}

Just passing an extra argument to the new method does not work:

UserJsonDecorator.new(@user,options)

Any ideas?

Solution

  • I was basically using it wrong.

    correct form to pass additional arguments is:

    UserJsonDecorator.new(@user).to_json(options)
