Ruby 1.8.7



Get the code:

git clone

In a terminal, navigate to the fixmytransport folder where this install guide lives.

You will also want to install mySociety's common ruby libraries. Run:

git submodule update --init

to fetch the contents of the submodule.

Copy config/general.yml-example to config/general.yml

Configure the database:

Install Postgres and PostGIS - OSX installers are available at

  • copy database.yml-example to database.yml in fixmytransport/config
  • edit it to point to your local postgresql database in the development and test sections and create the databases:

Become the 'postgres' user (sudo su - postgres) (or whatever user postgres is running as)

psql template1 to get into command tool

\l to list databases

CREATE DATABASE fixmytransport_development encoding = 'UTF8';
CREATE DATABASE fixmytransport_test encoding = 'UTF8';

Make sure that the user specified in database.yml exists, and has full permissions on this database.

ALTER USER <username> WITH PASSWORD '<password>';
GRANT ALL PRIVILEGES ON DATABASE fixmytransport_development TO <username>;
GRANT ALL PRIVILEGES ON DATABASE fixmytransport_test TO <username>;     
ALTER DATABASE fixmytransport_development OWNER TO <username>;
ALTER DATABASE fixmytransport_test OWNER TO <username>;

The following commands need to be run at the command line following db creation for each of fixmytransport_development and fixmytransport_test:

createlang  plpgsql [database name]
psql [yourdb] < /usr/local/pgsql/share/contrib/postgis-1.5/postgis.sql
psql [yourdb] < /usr/local/pgsql/share/contrib/postgis-1.5/spatial_ref_sys.sql

Also, SRID 27700 (British National Grid) is incorrect in some installs of PostGIS. After you’ve installed and got a PostGIS template, log in to it and make sure the proj4text column of SRID 27700 in the spatial_ref_sys table includes +datum=OSGB36.

Install additional packages

If you're using a Debian-based system, you should make sure that the packages listed in config/packages are all installed.

To load a new binary Postgres dump file:

  1. Create the file from an existing database with pg_dump -p [Postgres port number] --schema=public -Fc YOURDB > YOURDB.sql.dump
  2. rake db:load_from_binary FILE=YOURDB.sql.dump

Running the tests

If you want to run the RSpec tests continuously while developing, you can do this using ZenTest. You can install ZenTest and support for Rails with:

gem install ZenTest autotest-rails

Then you can run the following command in the fixmytransport directory:

RSPEC=true autotest

If you see many gem-related deprecation warnings when running the tests, such as:

NOTE: Gem.source_index is deprecated, use Specification. It will be removed on or after 2011-11-01.
Gem.source_index called from /home/mark/fixmytransport/config/../vendor/rails/railties/lib/rails/gem_dependency.rb:21.

... then your version of RubyGems is much more recent that the components of Rails in the vendor subdirectory. One solution to this is to downgrade to an earlier version of RubyGems with:

gem update --system 1.6.2
