Question

I’m writing a web app that lets users browse through attractions in regions, states and countries. Currently I have the app set up in a way where attractions belong to regions, regions belong to states, and states belong to countries.

What I’m trying to do is write the view for a State. I’m trying to come up with a way to get lists of regions and the attractions in them, so something like

STATE

• Region 1
  • Attraction 1
  • Attraction 2
• Region 2
  • Attraction 3
  • Attraction 4

but I have been unable to come up with a way to do this that feels “right”.

I’m using Sinatra and Datamapper with MySQL, if that helps.

Answer 1

With the states data :

@states=State.all

In the view (HAML) :

=@states.each do |state|
  %h6 state.name
  %ul
    =state.regions.each |region|
      %li
        #{region.name}
        %ul
          =region.attractions.each do |attraction|
            %li attraction.name
