This is a general guide to setting up an Open Food Network development environment on your local machine. If you want to setup OFN on a server, please have a look at the ofn-install deployment guide.
Head to our wiki on Learning Rails to find some good starting points.
The fastest way to make it work locally is to use Docker, you only need to setup git, see the Docker setup guide. Otherwise, for a local setup you will need:
- Ruby and bundler (check current Ruby version in .ruby-version file)
- PostgreSQL database
- Redis (for background jobs)
- Chrome (for testing)
The following guides will provide OS-specific step-by-step instructions to get these requirements installed:
If you are likely to need to manage multiple version of ruby on your local machine, we recommend version managers such as rbenv or RVM.
For those new to Rails, the following tutorial will help get you up to speed with configuring a Rails environment.
So you have set up your local environment according to the requirements listed above. If you're planning on contributing code to the project (which we LOVE), it is a good idea to begin by forking this repo using the Fork button in the top-right corner of this screen. You should then be able to use git clone to copy your fork onto your local machine:
git clone https://github.com/YOUR_GITHUB_USERNAME_HERE/openfoodnetwork
Jump into your new local copy of the Open Food Network:
cd openfoodnetwork
And then add an upstream remote that points to the main repo:
git remote add upstream https://github.com/openfoodfoundation/openfoodnetwork
Fetch the latest version of master from upstream (ie. the main repo):
git fetch upstream master
First, you need to create the database user the app will use by manually typing the following in your terminal:
$ sudo -u postgres psql -c "CREATE USER ofn WITH SUPERUSER CREATEDB PASSWORD 'f00d'"This will create the "ofn" user as superuser and allowing it to create databases. If this command fails, check the troubleshooting section for an alternative.
Next, it is strongly recommended to run the setup script.
$ script/setupIf the script succeeds you're ready to start developing. If not, take a look at the output as it should be informative enough to help you troubleshoot.
Now, your dreams of spinning up a development server can be realised:
bundle exec rails server
Go to http://localhost:3000 to play around!
To login as the default user, use:
email: [email protected]
password: ofn123
Tests, both unit and integration, are based on RSpec. To run the test suite, first prepare the test database:
bundle exec rake db:test:prepare
Then the main application tests can be run with:
bundle exec rspec spec
The tests of all custom engines can be run with:
bundle exec rake ofn:specs:engines:rspec
Note: If your OS is not explicitly supported in the setup guides then not all tests may pass. However, you may still be able to develop.
Note: The time zone on your machine should match the one defined in the .env[.*] file.
Once npm dependencies are installed, AngularJS tests can be run with:
./script/karma run
If you want karma to automatically rerun the tests on file modification, use:
./script/karma start
Do not forget to run rake tmp:cache:clear after locales are updated to reload I18n js translations.
The project is configured to use rubocop to automatically check for style and syntax errors.
You can run rubocop against your changes using:
rubocop
Below are fixes to potential issues that can happen during the installation process. If these don't solve the problem, or it's not listed, feel free to reach out to the Developer Community on slack. We usually respond pretty quickly.
If the $ sudo -u postgres psql -c "CREATE USER ofn WITH SUPERUSER CREATEDB PASSWORD 'f00d'" command doesn't work, you can run the following commands instead:
$ createuser --superuser --pwprompt ofn
Enter password for new role: f00d
Enter it again: f00d
$ createdb open_food_network_dev --owner=ofn
$ createdb open_food_network_test --owner=ofn
If these commands succeed, you should be able to continue the setup process.
