Technical Task - Developer, Platform team, ReedPop

Hello,

In this task you will be working on a simple data platform for a news website.

The project is built in Python and uses the Django framework (v3.2).

You will be asked to:

• Extend the models to include tags.
• Create "fixtures" to produce random, dummy model data.
• Add some tests for your work.

The task is designed to demonstrate your ability to use new technology, to interpret specifications, solve programming problems, and show an understanding of test coverage.

The task is intended to take no more than 2 or 3 hours. If you overrun significantly then please get in touch as we may have misjudged the timing of the task.

Getting set up

Install Python 3 if you don't already have it (should be fine on macOS and Linux).

Then, in a shell, run the following to set up the project:

git clone https://github.com/gamernetwork/tech-task-platform-2021.5.1.git
cd tech-task-platform-2021.5.1

# set up a python virtual environment
python3 -m venv .env

# install Django into this environment
.env/bin/pip install -r requirements.txt

# set up the database
.env/bin/python manage.py migrate

You will now have a db.sqlite3 file in your project directory. This is your database.

If you want to access the admin site, create yourself a superuser account:

.env/bin/python manage.py createsuperuser

Then start a local development server (errors and access logs will show here):

.env/bin/python manage.py runserver

Finally, access the backend here: http://127.0.0.1:8000/admin/ and log in using the superuser account you created.

Note regarding the database

If you get into a mess with migrations, etc, you can just move/delete the db.sqlite3 file and re-run the migrate and createsuperuser steps again to get back to a fresh installation.

Tasks

Please do the following:

1. Add a Tag model with the following fields:
   • Name (up to 200 characters, unique)
   • Created at (date/time, automatically set when model is created)
2. Add a field to the Post model allowing a post to be associated with zero or more tags.
3. Add a method or property to Post that returns a single string containing the name of all tags associated with the post, in alphabetical order.
   • For example, if a post is tagged with "Gaming", "Featured" and "Xbox", the output might be "Featured, Gaming, Xbox"
   • Ensure that this method can handle a post that has no tags.
4. Add suitable test cases for the method you created above.
5. Populate the stub methods in the Fixtures class. You can use the faker library to create some suitable data to insert.
6. Add suitable test cases for the methods in the Fixtures class.

Task reference information

• Refer to the Workflow section on migrations for steps to get your model changes into the database.
• Refer to "Writing our first test" for information about writing and running tests.
• A command has been set up to run a set of fixtures, which you may use for manual testing:

  .env/bin/python manage.py run_fixtures
