Ruby & Rails

Rails 4.2
Ruby 2.3+

Database

Postgresql 9.1 (or 9.1, 8.4)
Postgis 2 (may work with 1.5)

Installation Dependencies

Check out the Vagrant section lower down in the readme if you want to get started quickly.

on Ubuntu 16.04 LTS

apt-get install -y ruby ruby-dev postgresql-9.3-postgis-2.1 postgresql-server-dev-all postgresql-contrib build-essential git-core libxml2-dev libxslt-dev imagemagick libmapserver1 gdal-bin libgdal-dev ruby-mapscript nodejs

Due to a bug with the gdal gem, you may need to disable a few flags from your ruby rbconfig.rb see zhm/gdal-ruby#4 for more information

Then install the gem files using bundler

bundle install

Configuration

Create and configure the following files

config/secrets.yml
config/database.yml
config/application.yml

In addition have a look in config/initializers/application_config.rb for some other paths and variables, and also config/environments/development.rb if you rather not use the /warper relative path.

Database creation

Create a postgis database

sudo -u postgres createdb mapwarper_development
psql mapwarper_development -c "create extension postgis;"
RAILS_ENV=development bundle exec rake db:migrate

Database initialization

Creating a new user

user = User.new
user.login = "super"
user.email = "super@superxyz123.com"
user.save

role = Role.find_by_name('super user')

permission  = Permission.new
permission.role = role
permission.user = user
permission.save

role = Role.find_by_name('administrator')
permission = Permission.new
permission.role = role
permission.user = user
permission.save

Also, you can run rake db:seed to add in a default admin user

Development

Via Vagrant, there is a Vagrantfile you can use which uses the /lib/vagrant/provision.sh provision script. Note: the default Vagrantfile is configured to take 8GB RAM. To use this file type:

vagrant up

to get and install the virtual machine - this will also install the libraries and depencies and ruby gems for mapwarper into the virtual machine. See /lib/vagrant/provision.sh for more details about this process.

After that runs, type vagrant ssh to login and then you can:

cd /srv/mapwarper
rails c

Create a user in the console, as shown above and then exit. Then start the server in a relative url root use thin:

rails s -b 0.0.0.0

and then browse to http://localhost:3000/

In non-Vagrant circumstances you may want to run it just using rails s.

Deployment instructions

The system can use capistrano for deployment.

Making Code Changes and Deployment

There are two main changes to the system. Changes to checked in code, and changes to configuration files. Some configuration files (/config/*) are not stored in the repository. To change these you need to ssh into the server and change the file. Some .example files are provided for reference.

Changes to checked in code.

Develop, patch the code locally and get it running. Probably the easiest way to start developing is via Vagrant, see above for more details. Once you have Vagrant running, these are some useful commands to make sure updates are reflected:

If assets had been changed (images, JS, CSS etc.) or if you just want to be safe:

RAILS_ENV=production rake assets:clobber

RAILS_ENV=production rake assets:precompile

If necessary to run rails console commands:

RAILS_ENV=production rails console

To restart the server:

touch tmp/restart.txt

To restart the Apache server (not needed in almost all cases):

sudo service apache2 restart

Changes to config file:

ssh into the server
Find the desired config file
Edit the file
Restart the warper: touch tmp/restart.txt
