Settings

A Daiquiri application can be customised using various settings. Since Daiquiri is based on Django, we use its build-in settings system. Almost every setting has a default value, which is set in the Daiquiri library. The core settings are defined in the daiquiri.core.settings module:

Additional settings, which concern only a single Daiquiri module are defined in the settings module of the particular module:

All settings can be changed for your particular app in config/settings/base.py (app specific) or config/settings/local.py (machine specific, and ignored by git). In addition, selected settings can be configured as environment variables, in particular using the .env file app directory:

Setting Default
SECRET_KEY 🚫
SITE_URL http://localhost:8000
DEBUG False
ASYNC False
ALLOWED_HOSTS ['localhost']
TIME_ZONE 'UTC'
PROXY False
ADMINS []
DATABASE_APP 🚫
DATABASE_DATA 🚫
TAP_SCHEMA TAP_SCHEMA
TAP_UPLOAD TAP_UPLOAD
OAI_SCHEMA OAI_SCHEMA

In the .env file, lists are seperated by comma, e.g. ADMINS=Anna Admin <admin@example.com>, Manni Manager <manager@example.com>. Since SECRET_KEY, DATABASE_APP, and DATABASE_DATA have no default value, they need to be set in any case.

In the following all settings, which can be changed from their default values to customize you particular Daiquiri app are described in detail:
