GNU Health/WebDAV

This section applies to version 3.4 of GNU Health.

Introduction

GNU Health provides its own WebDAV and Caldav server. It allows to create and associate calendars to health professionals. The calendar entries for appointments, hospitalizations and other resources can be accessed via WebDAV clients.

Calendar capabilities of GNU Health using WebDAV protocol

Installation

To install the webdav functionality, you need to install the following packages

pywebdav3-gnuhealth : Python3 webDAV library for GNU Health (installed automatically when using the standard installation method)
health_webdav3_server : GNU Health webdav server, for Python3 and GNUHealth support
health_caldav : GNU Health calendar package with webdav3 and caldav support
health_calendar : Main calendar for appointments
health_inpatient_calendar : Hospitalization / bed calendar support

If you have installed GNU Health from openSUSE packages, everything is already installed.

Setting up the WebDAV server

Check the settings for the host and port of the GNUHealth WebDAV server

[webdav]
listen = *:8080

In this sample from the default configuration file, the WebDAV server will accept connections from any network interface, on port 8080.

You can change the values editing the configuration file, using the command

editconf

Creating and Assigning Calendars

Creating a Calendar in GNU Health

In order to access a calendar, we first need to create it, and assign it to a user on our GNU Health Tryton instance.

To create a calendar, Follow the link:

Calendar -> Calendars

Assignment od the calendar to the login user.

Define a name to the calendar (use only letters, without punctuation or non-ascii characters).
Assign the calendar to a user (in this example, we assign the "Cordara" Calendar to the "Administrator" user
Finally, assign the calendar to the user that will login to GNU Health. In this example, the user associated to the "Cordara" calendar is "Administrator", with username "admin". The credentials (username and password) used in the calendar are the same as for login into the GNU Health HMIS. For security reasons, use a SSL enabled connection.

Running the server

To start the webdav server, do the following

Check that the GNU Health server is running
Change to the webdav server directory

cdmods
cd health_webdav3_server/bin

Execute the server

./gnuhealth-webdav-server

openSUSE comes with a systemd-service called gnuhealth-webdav. It expects the database name as parameter. If your database is gnuhealth34, you can start the service with

systemctl start gnuhealth-webdav@gnuhealth34
