System Requirements

  • Ruby v1.8.7 or v1.9.2
  • MySQL v4.1.1 or later (v5+ is recommended), SQLite v3.4 or later, or Postgres 8.4.8 or later.
  • ImageMagick (optional, only needed if you would like to use avatars)

(Ruby on Rails v3 and other gem dependencies will be installed automatically by Bundler.)


Upgrading from previous versions of Fat Free CRM

If you are upgrading from version 0.10.1 or below to the latest Rails 3.x version, your database schema needs to be updated.

Please run the following commands in this order:

bundle install --without heroku   # Installs gem dependencies
rake crm:upgrade:schema           # Updates your schema to use the new timestamped migrations
rake db:migrate                   # Runs any new database migrations.

Install on Heroku

You will need the heroku gem on your system.

gem install heroku

To set up Fat Free CRM on Heroku, run the following commands:

app_name="{{organization-crm}}" # <- Replace with your desired application name
cp config/settings.yml.example config/settings.yml
git add -f config/settings.yml
git commit -m "Added default settings.yml"
heroku create $app_name --stack cedar
git push heroku master
heroku run rake crm:setup USERNAME=admin PASSWORD=admin
heroku config:add HEROKU=true

Install locally, or on a server

Set Up Configuration (Database & Settings)

Fat Free CRM supports PostGreSQL, MySQL and SQLite databases. The source code comes with sample database configuration files, such as: config/database.mysql.yml for MySQL and config/database.sqlite.yml for SQLite.

Based on your choice of database, create config/database.yml:

cp config/database.mysql.yml config/database.yml
  • Edit config/database.yml and specify database names and authentication details.

  • Then, edit your Gemfile and uncomment only your chosen database.

Install Gem Dependencies

After you have uncommented the right database adapter in your Gemfile, run the following command from the application's root directory:

bundle install --without heroku

Create Database

Now you are ready to create the database:

rake db:create

Set Up Application

The next step is to load default Fat Free CRM settings, such as menu structures, default colors, etc. and create the Admin user.

Using the provided sample, create your config/settings.yml:

cp config/settings.yml.example config/settings.yml
  • Edit config/settings.yml and configure any required settings, such as your host, base URL and language (locale).

Next, run the following rake task:

rake crm:setup

The previous command will prompt you for an admin user, password and email. If you want to run this task without any user input, you can set the following variables:

rake crm:setup USERNAME=admin PASSWORD=password

Load Demo Data (Optional)

You can test drive Fat Free CRM by loading sample records that are generated on the fly mimic the actual use.

IMPORTANT: Loading demo will delete all existing data from your database.

rake crm:demo:load

Among other things the demo generator creates 8 sample user records with the following usernames: aaron, ben, cindy, dan, elizabeth, frank, george, and heather. You can log in with any of these names using the name as password. The demo site at provides access as a sample user as well.

You can reset the database and reload demo data at any time by using:

rake crm:demo:reload

Run the App

Now you should be able to launch the Rails server and point your web browser to http://localhost:3000
