Seeding Rails App With RESTful Address Data

Grabbing data from Restful webservices has never been easier. I use this code in the Rails /db/seeds.rb file to grab data from the Danish webservice with addresses, municipalities, regions, etc.

I decided to import the data into a local database to ensure it could work offline.

Code from /db/seeds.rb file:

Now I can access municipalities in a grouped selectbox like so in the view code:


<%
 options = option_groups_from_collection_for_select(Region.all, :kommuner, :name, :id, :name) 
%>

<%=
 f.select("kommune_id", options, {}, {:class => "short"}) 
%>

The final result rendered in the user interface:

This code is based on Rails 2.3.5.

    Great stuff and thanks for doing all of this.

    Quick question…given that I’m already using Factories for my testing, what is the advantage of using seed_fu over a custom rake task using Factories? It seems like I’d be just re-creating my Factory code.

    Note that my comments relate to creating data for development and testing purposes – not seeding a database with static data (e.g. AK, AZ….).

    thanks again, great stuff
