# Your Auth Project
## Overview
# Folder structure
When installing Alliance Auth you are instructed to run the `allianceauth start` command which generates a folder containing your auth project. This auth project is based off Alliance Auth but can be customized how you wish.
### The myauth Folder
## The myauth folder
The first folder created is the root directory of your auth project. This folder contains:
- the `manage.py` management script used to interact with Django
- a preconfigured `supervisor.conf` Supervisor config for running Celery (and optionally Gunicorn) automatically
- a `log` folder which contains log files generated by Alliance Auth
### The myauth Subfolder

- a preconfigured `supervisor.conf` Supervisor config for running Celery (and optionally Gunicorn) automatically
- a `log` folder which contains log files generated by Alliance Auth
## The myauth subfolder
Within your auth project root folder is another folder of the same name (a quirk of Django project structures). This folder contains:
- a Celery app definition in `celery.py` for registering tasks with the background workers
- a web server gateway interface script `wsgi.py` for processing web requests
- the root URL config `urls.py` which Django uses to direct requests to the appropriate view
- a Celery app definition in `celery.py` for registering tasks with the background workers
- a web server gateway interface script `wsgi.py` for processing web requests
- the root URL config `urls.py` which Django uses to direct requests to the appropriate view
There are also two subfolders for `static` and `templates` which allow adding new content and overriding default content shipped with Alliance Auth or Django.
And finally the settings folder.
### Settings Files
## Settings Files
With the settings folder lives two settings files: `base.py` and `local.py`

Your auth project comes with four log file definitions by default. These are created in the `myauth/log/` folder at runtime.
- `allianceauth.log` contains all `INFO` level and above logging messages from Alliance Auth. This is useful for tracking who is making changes to the site, what is happening to users, and debugging any errors that may occur.
- `worker.log` contains logging messages from the Celery background task workers. This is useful for monitoring background processes such as group syncing to services.
- `beat.log` contains logging messages from the background task scheduler. This is of limited use unless the scheduler isn't starting.
- `gunicorn.log` contains logging messages from Gunicorn workers. This contains all web-sourced messages found in `allianceauth.log` as well as runtime errors from the workers themselves.

When asking for assistance with your auth project be sure to first read the logs, and share any relevant entries.
## Custom Static and Templates
Within your auth project exists two folders named `static` and `templates`. These are used by Django for rendering web pages. Static refers to content Django does not need to parse before displaying, such as CSS styling or images. When running via a WSGI worker such as Gunicorn static files are copied to a location for the web server to read from. Templates are always read from the template folders, rendered with additional context from a view function, and then displayed to the user.
You can add extra static or templates by putting files in these folders. Note that changes to static requires running the `python manage.py collectstatic` command to copy to the web server directory.
It is possible to overload static and templates shipped with Django or Alliance Auth by including a file with the exact path of the one you wish to overload. For instance if you wish to add extra links to the menu bar by editing the template, you would make a copy of the `allianceauth/templates/allianceauth/base.html` file to `myauth/templates/allinceauth/base.html` and edit it there. Notice the paths are identical after the `templates/` directory - this is critical for it to be recognized. Your custom template would be used instead of the one included with Alliance Auth when Django renders the web page. Similar idea for static: put CSS or images at an identical path after the `static/` directory and they will be copied to the web server directory instead of the ones included.
## Custom URLs and Views
It is possible to add or override URLs with your auth project's URL config file. Upon install it is of the form:
```
import allianceauth.urls
urlpatterns = [
url(r'', include(allianceauth.urls)),
]
```
This means every request gets passed to the Alliance Auth URL config to be interpreted.
If you wanted to add a URL pointing to a custom view, it can be added anywhere in the list if not already used by Alliance Auth:
```
import allianceauth.urls
import myauth.views
urlpatterns = [
url(r'', include(allianceauth.urls)),
url(r'myview/$', myauth.views.myview, name='myview'),
]
```
Additionally you can override URLs used by Alliance Auth here:
```
import allianceauth.urls
import myauth.views
urlpatterns = [
url(r'account/login/$', myauth.views.login, name='auth_login_user'),
url(r'', include(allianceauth.urls)),
]
```
## Adding and Removing Apps
Your auth project is just a regular Django project - you can add in [other Django apps](https://djangopackages.org/) as desired. Most come with dedicated setup guides, but in general:
- add `'appname',` to your `INSTALLED_APPS` setting
- run `python manage.py migrate`
- run `python manage.py collectstatic`
If you ever want to remove an app, you should first clear it from the database to avoid dangling foreign keys: `python manage.py migrate appname zero`. Then you can remove it from your auth project's `INSTALLED_APPS` list.
