A re-introduction of the web application for ESRG Knights of the Kitchen Table.

1. Install the latest version of Python 3. If you are on Windows, you can download Python from [python.org]. If you are not, check if you already have a recent version by runnning python3 --version. As of writing, Python 3.5 or higher is recent enough, but this may change in the future.
2. Clone this git repository using Git, preferably to a location without spaces or other non-alphanumerical characters in it. Having spaces or other non-alphanumerical characters in the path can cause strange issues later down the road.
3. Start a command prompt/terminal in the folder you have put the Squire sources in. Use this terminal to execute the rest of the commands (in order)
4. Create a new virtual environment. On Windows, this can be done by running py -3 -m venv venv. On other operating systems this is done by running python3 -m venv venv. This ensures that this project's dependencies don't conflict with other Python applications on your system.
5. Activate your virtual environment by running venv\Scripts\activate if you are on Windows. Otherwise run source venv/bin/activate. If this is successful, your terminal line will start with (venv). We assume that any commands ran beyond this point are ran inside a virtualenv for this project. This step needs to be done for each terminal you are using for this project, so if you later return to continue working on the program, you need to rerun this command.
6. Install the dependencies: pip install -r requirements/dev.txt. These dependencies include common dependencies (such as Django) as well as dev-dependencies that speed up or ease the development process (such as coverage.py). For more information about dependencies, view the Dependencies section below.
7. Setup the database by running python manage.py migrate. This ensures your database can store the items we expect to store in it.
8. Start the server: python manage.py runserver. This starts a web server, which you can access using your webbrowser and going to localhost:8000.
9. If wanting to use functionality that involves sending emails (such as resetting a password), then you'll also need to run the following command in another command prompt/terminal: python -m smtpd -n -c DebuggingServer localhost:1025. This will mimic an smtp email server. Any emails that would normally be sent will instead show up in this terminal.
   
   

Because we haven't got all year, we use some dependencies to help speed up the development process. These dependencies, called dev-dependencies, will however not be used in a production environment (as they are only used for development). Likewise, prod-dependencies can exist as well: dependencies that are needed in production but not during development. Lastly, there are some dependencies (such as Django) that are needed in any environment. These are called common-dependencies.

In order to keep things clear and to make it easier to use, these requirements are split into different files:

• requirements/common.txt: Contains common requirements. I.e. those that are needed for any environment.
• requirements/dev.txt: Contains development requirements. I.e. those that are needed during development. Automatically includes the common requirements.
• requirements/prod.txt: Contains production requirements. I.e. those that are needed during production. Automatically includes the common requirements.
• requirements/ci.txt: Contains all continuous integration requirements. Automatically includes the production requirements.
• requirements.txt: Shorthand for requirements/prod.txt. Necessary since some services (such as GitHub's Dependency Graph) look for files with this specific name.

Django automatically recognises test files of the format <python_app>/tests.py. Each test case is described using Django's TestCase class, which can be imported using from django.test import TestCase.

More information on Django Testcases can be accessed online at the Django Documentation.

NB: It is important to not use the unittest.TestCase class!

Squire makes use of Coverage.py. As taken from their website, "Coverage.py is a tool for measuring code coverage of Python programs. It monitors your program, noting which parts of the code have been executed, then analyzes the source to identify code that could have been executed but was not." Coverage.py also provides nice functionality to visualise code coverage.

Running tests can be done using the following command: coverage run manage.py test.

Obtaining the coverage report in the command line can then be done using: coverage report.

Alternatively, the following command can be used to obtain the coverage report in HTML-format: coverage html.

NB: If an error occurs before the tests are run, then make sure you have created a /coverage-folder in the root of the repository. Also make sure you've actually installed the coverage.py package by calling pip install -r requirements/dev.txt
NB: You'll need to re-run the first command each time you make a change to your source code or test file in order to obtain an up-to-date coverage report.

In order to exclude files that do not need to be tested (and show up in the coverage report), you'll need to edit .coveragerc in the root of the repository. Even though the file has no extension, it should be in a .ini file format. More information on this configuration file can be accessed online at coverage.py's website.

NB: Only files with a .py extension are tested by default.

There are still several things that need to be done before the application can be run. First and foremost, DEBUG = False should be set in squire/settings.py. Moreover, files in the media folder will need to be served. This should be set up on the server on which Squire is run itself.

Before making anything public, run python manage.py check --deploy to ensure that there are no futher security warnings.

Run python manage.py migrate Run python manage.py runserver

Setting up things like achievements can be time consuming. Hence, it is possible to use data that was set up earlier. For instance, achievement data can be dumped to a file using python manage.py dumpdata achievements --exclude achievements.claimant --indent 2 > achievements.json. After that, the data can easily be loaded during production using python manage.py loaddata achievements.json (after running the migrate but before running runserver). Note that the images inside the media folder are not automatically imported; only their file path is!
