API project template based on Django 2.1 (and higher), and DRF 3.8 (and higher).

Technologies:

• Django REST Framework (DRF)
• DRF Cache support (for rdb and cassandra models)
• DRF Throttle support by ViewSet and request action (retrieve, list, create, update, etc.)
• DRF Token Authentication (no username needed, Bearer token)
• PostgreSQL backend for miscellaneous models (User, Token, etc.)
• DSE Cassandra backend for business models
• Configuration of Cassandra-DRF serializers
• Support for JSONField in Cassandra (Text field)
• Support for pre/post callbacks in CassandraModel (DRF cache clean actions)
• DRF-Haystack-DSE support to support fast searches (DSE-Solr) with model examples
• Command to synchronize the DSE tables with the needed search indexes
• Swagger view of the API documentation
• Google App Engine Flexible (Custom) support
• PGBouncer Connection Pool supported in the Docker image

To run the tests we only need to run the following instruction:

$ python manage.py test --testrunner=caravaggio_rest_api.testrunner.TestRunner

The output will be something like:

Creating test database for alias 'default'...
Creating test database for alias 'cassandra'...
Creating keyspace test_apian [CONNECTION cassandra] ..
Syncing davinci_crawling.example.models.BovespaCompany
Syncing davinci_crawling.example.models.BovespaCompanyFile
Syncing davinci_crawling.example.models.BovespaAccount
System check identified no issues (0 silenced).
...
...

Avoid the destruction of the database after the tests have finished and the indexes synchronization:

$ python manage.py test --testrunner=caravaggio_rest_api.testrunner.TestRunner --keepdb --keep-indexes

In Sierra MAC OSX:

$ sudo chown -R $(whoami) $(brew --prefix)/*
$ sudo install -d -o $(whoami) -g admin /usr/local/Frameworks
$ brew install gdal
