InvenTree Configuration
=======================

   :caption: Configuration
   :hidden:

Admin users will need to adjust the InvenTree installation to meet the particular needs of their setup. For example, pointing to the correct database backend, or specifying a list of allowed hosts.

The Django configuration parameters are found in the normal place (``settings.py``). However the settings presented in this file should not be adjusted as they will alter the core behaviour of the InvenTree application.

To support install specific settings, a simple configuration file ``config.yaml`` is provided. This configuration file is loaded by ``settings.py`` at runtime. Settings specific to a given install should be adjusted in ``config.yaml``.

The default configuration file launches a *DEBUG* configuration with a simple SQLITE database backend. This default configuration file is shown below:

.. literalinclude :: ../InvenTree/config.yaml
   :language: yaml

Database Options
----------------

InvenTree provides support for multiple database backends - any backend supported natively by Django can be used. 

Database options are specified under the *database* heading in the configuration file. Any option available in the Django documentation can be used here - it is passed through transparently to the management scripts.

**SQLITE:**
By default, InvenTree uses an sqlite database file : ``inventree_db.sqlite3``. This provides a simple, portable database file that is easy to use for debug and testing purposes. 


**MYSQL:** MySQL database backend is supported with the native Django implemetation.

**POSTGRESQL:** PostgreSQL database backend is supported with the native Django implementation. Note that to use this backend, the ``psycopg2`` Python library must first be installed.

Allowed Hosts / CORS
--------------------

By default, all hosts are allowed, and CORS requests are enabled from any origin. **This is not secure and should be adjusted for your installation**. These options can be changed in the configuration file.

For further information, refer to the following documentation:

* `Django ALLOWED_HOSTS <https://docs.djangoproject.com/en/2.2/ref/settings/#allowed-hosts>`_
* `Django CORS headers <https://github.com/OttoYiu/django-cors-headers>`_

Uploaded File Storage
---------------------

By default, uploaded files are stored in the local direction ``./media``. This directory should be changed based on the particular installation requirements.

Backup Location
---------------

The default behaviour of the database backup is to generate backup files for database tables and media files to the user's temporary directory. The target directory can be overridden by setting the *backup_dir* parameter in the config file.
