Doubtfire is a feedback-driven learning support system.
See Doubtfire Deploy for instructions on deploying, and contributing, to the Doubtfire project.

You may choose to keep your environment variables inside a .env file using key-value pairs:
DF_INSTITUTION_HOST=doubtfire.unifoo.edu.au
DF_INSTITUTION_NAME="University of Foo"
You can also keep multiple .env files for different environments, e.g.: .env.production is different to .env.develoment. Doubtfire uses the dotenv gem to make this happen.
Once you've installed using either in install script or the manual install steps.
$ bundle exec rails s
You should see all the Doubtfire endpoints at http://localhost:3000/api/docs/, which means the API is running.
You can perform developer-specific tasks using rake. For a list of all tasks, execute in the root directory:
rake --tasks
Our aim with testing Doubtfire is to migrate to a Test-Driven Development strategy, testing all new models and API endpoints (although we plan on writing more tests for existing models and API endpoints). If you are writing a new API endpoint or model, we strongly suggest you include unit tests in the appropriate folders (see below).
To run unit tests, execute:
$ rake testUnit tests are located in the test directory, where model tests are under
the model subdirectory and API tests are under the api subdirectory.
Any helpers should be included in the helpers subdirectory and helper
modules should be written under the TestHelpers module.
