Doubtfire is a feedback-driven learning support system.
See Doubtfire Deploy for instructions on deploying, and contributing, to the Doubtfire project.
Doubtfire requires multiple environment variables that help define settings about the Doubtfire instance running. Whilst these will default to other values, you may want to override them in production.
| Key | Description | Default |
|---|---|---|
DF_AUTH_METHOD | The authentication method you would like Doubtfire to use. Possible values are database for standard authentication with the database, ldap for LDAP, aaf for AAF Rapid Connect, or SAML2 for SAML2.0 auth. | database |
DF_STUDENT_WORK_DIR | The directory to store uploaded student work for processing. | student_work |
DF_INSTITUTION_NAME | The name of your institution running Doubtfire. | University of Foo |

DF_SECRET_KEY_DEVISE | The secret key provided to Devise. | Default key provided. |
DF_SECRET_KEY_MOSS | The secret key provided to Moss for plagiarism detection. This value will need to be set to run rake submission:check_plagiarism (otherwise you won't need it). You will need to register for a Moss account to use this. | No default. |
DF_INSTITUTION_PRIVACY | A statement related to the need for students to submit their own work, and that this work may be uploaded to 3rd parties for the purpose of plagiarism detection. | Default statement provided |
DF_INSTITUTION_PLAGIARISM | A statement clarifying the terms plagiarism and collusion. | Default statement provided |

DF_FFMPEG_PATH | The path of to the ffmpeg binary for audio processing. | ffmpeg |
DF_REDIS_CACHE_URL | The redis URL for rails used for development and production, ignored in the test env. | redis://localhost:6379/0 |
DF_REDIS_SIDEKIQ_URL | The redis URL for sidekiq. A working redis server is mandatory for sidekiq in all environments. | redis://localhost:6379/1 |
If you have chosen to use AAF Rapid Connect authentication, then you will also need to provide the following:
| Key | Description | Default |
|---|---|---|
DF_AAF_ISSUER_URL | The URL of the AFF issuer, either https://rapid.test.aaf.edu.au for testing or https://rapid.aaf.edu.au for production. | https://rapid.test.aaf.edu.au |
DF_AAF_AUDIENCE_URL | The URL of the AAF registered application. | No default - required |
DF_AAF_CALLBACK_URL | The secure endpoint within your application that AAF Rapid Connect should POST responses to. It must end with /api/auth/jwt to access the Doubtfire JWT authentication endpoint. | No default - required |
DF_AAF_UNIQUE_URL | The unique URL provided by AAF Rapid Connect used for redirection out of Doubtfire. | No default - required |
DF_AAF_IDENTITY_PROVIDER_URL | The URL of the AAF-registered identity provider. | No default - required |
DF_AAF_AUTH_SIGNOUT_URL | The URL to redirect to on sign out in order to log out of AAF Rapid Connect. | No default - required |
DF_SECRET_KEY_AAF | The secret used to register your application with AAF. | secretsecret12345 |
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.
