About the project:

Contribute to Mozilla - One task at a time, One day at a time.

One and Done gives users a wide variety of ways to contribute to Mozilla. You can pick an easy task that only takes a few minutes - or take on a bigger challenge. This includes working on manual testing, automation, bug verification, mobile testing and more. Tasks are from a variety of Mozilla teams - so you can get involved with Automation, Firefox OS, Desktop Firefox, Mozilla websites, Services, Thunderbird and more.

Development Setup

These instructions assume you have git, python, and pip installed. If you don't have pip installed, you can install it with easy_install pip.

  1. Start by getting the source:

    $ git clone
    $ cd oneanddone

    Note you may want to fork and clone the repo as described in the github docs if you are doing active development.

  2. Create a virtualenv for One and Done. Skip the first step if you already have virtualenv installed.

    $ pip install virtualenv
    $ virtualenv venv
    $ source venv/bin/activate
  3. Set up PostgreSQL locally. The PostgreSQL Installation Documentation explains how to do this.

  4. Create the initial empty database; make sure it's utf8:

    # Log into the postgres console
    # using your username and password
    $ psql -U your_username

    In the mysql console:

    CREATE DATABASE oneanddone;

    To run all parts of the application, you will eventually need to populate this empty database with some example data, especially Tasks. There are many ways to populate the database. The method you choose may depend on the kind of data you want to add.

    • Use the create/edit features of your local One and Done instance. For example sign in with an administrator account and go to the /tasks/create/ URL of the app to create Tasks.
    • Use the Django admin section of your local One and Done instance by going to the /admin URL -- this also relies on an admin account. You can define Task Teams here, for example.
    • Use an external tool like PgAdmin.
    • Ask another active developer for a dump of their local database.
  5. Install the requirements:

    $ ./bin/ install -r requirements/requirements.txt

    Note: On OS X (in particular 10.8.5, Xcode 5.1), you may encounter the following error: clang: error: unknown argument. '-mno-fused-madd'. Try running peep with the ARCHFLAGS environment variable set, as follows: ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future ./bin/ install -r requirements/requirements.txt

  6. Establish your local settings by copying oneanddone/settings/ to oneanddone/settings/

    $ cp oneanddone/settings/ oneanddone/settings/

    The default settings in this file should work fine for a local dev environment, but the file is commented to describe how it can be customized. For example, if you wish to use memcached for caching instead of local memory, you can change the CACHES section to read:

    CACHES = {
       'default': {
           'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
           'LOCATION': '',
           'TIMEOUT': 600,
  7. Establish your local environment by copying .env-dist to .env:

    $ cp .env-dist .env

    As above, the default settings in this file should work fine for a local dev environment.

  8. Initialize your database structure:

    $ python migrate

    Once finished, the migrate command should produce a message about which models have been migrated, similar to that shown below.

    Operations to perform:
     Synchronize unmigrated apps: authtoken, rest_framework, cookies, base, session_csrf
     Apply all migrations: tasks, users, sessions, admin, auth, contenttypes
    Synchronizing apps without migrations:
     Creating tables...
       Creating table authtoken_token
     Installing custom SQL...
     Installing indexes...
    Running migrations:
     Applying contenttypes.0001_initial... OK
     Applying auth.0001_initial... OK
     Applying admin.0001_initial... OK
     Applying sessions.0001_initial... OK
     Applying tasks.0001_initial... OK
     Applying users.0001_initial... OK


One and Done uses BrowserID, a.k.a. Mozilla Persona, for user authentication. To add users to your local database, simply sign into your local One and Done instance. You may want to use dummy email accounts as described in Mozilla's guide to testing Persona.

You need at least one superuser to be able to develop and test administrative features of the project. You can create as many superusers as you like with python createsuperuser. After that, sign into your local One and Done instance with the superuser's email address as usual.

Applying Migrations

We're using built in Django database migrations. To apply the migrations, run the following:

   $ ./ migrate

If you make changes to an existing model, say oneanddone.tasks, you will need to regenerate the schema migration as follows:

   $ ./ makemigrations tasks

To generate a blank data migration:

   # ./ makemigrations --empty [model] [data_migration_name]
   # Example:
   $ ./ makemigrations oneanddone.tasks task_data 

Then fill in the generated file with logic, fixtures, etc. You can then apply this migration as above with:

   $ ./ migrate oneanddone.tasks

Running the Development Server

You can launch the development server like so:

$ python runserver

Running Unit Tests

You can run all the unit tests in verbose mode as follows:

$ python test -v 2

You can also run specific tests:

# All tests in tasks/tests/test_helpers module.
$ python test oneanddone.tasks.tests.test_helpers -v 2
# Just one test (PageUrlTests.test_basic)
$ python test oneanddone.tasks.tests.test_helpers:PageUrlTests.test_basic -v 2

REST API Support

There is a REST API support which enables:

  • Getting complete list of Tasks.
  • Getting details about a Task with a particular id.
  • Create and Delete Tasks with a particular id. The Task queries can be made by appending api/v1/task/ to the base url.

GET and DELETE queries example.

curl -X GET -H 'Authorization: Token d81e33c57b2d9471f4d6849bab3cb233b3b30468'
curl -X GET -H 'Authorization: Token d81e33c57b2d9471f4d6849bab3cb233b3b30468'
curl -X DELETE -H 'Authorization: Token d81e33c57b2d9471f4d6849bab3cb233b3b30468'
  • Getting a complete list of Users.
  • Getting details about a User with a particular email.
  • Create and Delete Users with a particular email. The User queries can be made by appending api/v1/user/ to the base url.

GET and DELETE queries example.

curl -X GET -H 'Authorization: Token d81e33c57b2d9471f4d6849bab3cb233b3b30468'
curl -X GET -H 'Authorization: Token d81e33c57b2d9471f4d6849bab3cb233b3b30468'
curl -X DELETE -H 'Authorization: Token d81e33c57b2d9471f4d6849bab3cb233b3b30468'

The API uses a Token Authentication system.

Token used in examples above is just a sample and actual Tokens can be generated from the admin panel by going to Authtoken > Tokens.

Functional Tests

Functional (Selenium) tests for oneanddone are maintained by the Web QA team and can be found at oneanddone-tests.
