This repo contains the backend code for Abidria project. This simple app aims to be a reference to discover interesting places and also to record our past experiences, sharing content with other people.
Application domain is composed by scenes
,
which are defined as something that happened
or can be done/seen in a located place.
A group of scenes
are defined as an experience
.
A person
can use api as anonymous guest.
Later, she can register specifying just username and email.
Posterior email confirmation is required to create content.
There is no password, so login will be implemented using email token system.
A person
can save
their favourite experiences
.
For the moment, the api is only consumed by abidria-android project.
Request:
You can specify mine
filter param to fetch only experiences you have created.
You can also specify saved
filter param to fetch only experiences you have saved.
Both params are set to false
by default, you can ignore them.

This project has been developed using Django framework, with Postgres as database and S3 as storage service.
Code structure follows a Clean Architecture approach (explained in detail here), emphasizing on code readability, responsibility decoupling and unit testing.
Authentication part is a little bit custom (to better fit requirements and also with learning purposes).
It doesn't uses Django User
model nor django-rest-framework, everything is handmade
(everything but cryptography, obviously :) ) and framework untied.
Special things are described here:
- There is anonymous guest user status. That allow users to enter to the app without register but we can track and analyze them. That also helps making app more secure because calls are made from guest users but authenticated and we can also control the number of registrations.
- There is no password. Guest user can register just with username and email, which makes registration process easier. Login will be implemented using token validation via email.
- User is called person. Developer tends to treat a user like a model or a number,
person
naming aims to remember who is really behind the screen.
Follow these instructions to start working locally on the project:
- Download code cloning this repo:
git clone https://github.com/jordifierro/abidria-api.git
- Install postgres and run:
./abidria/setup/postgres.sh
to create user and database.
- Run postgres:
postgres -D /usr/local/var/postgres &
- Install python version specified on
runtime.txt
and run:
virtualenv -p `which python3.6` ../env
- Add this to the end of
../env/bin/activate
file:
source abidria/setup/envvars.sh
- Get into the environment:
source ../env/bin/activate
and install dependencies:
pip install -r requirements.txt
- Migrate database:
python manage.py migrate
- Create django admin super user:
python manage.py createsuperuser
- Finally, you should be able to run unit and integration tests:
pytest # python tests
python manage.py test # django tests
Once we have made the first time setup, we can start everything up running:
source abidria/setup/startup.sh
