Configuration

Basic configuration update 

To update basic configuration (server name, database connection, languages, or set workers number or timeout), run:

sudo dpkg-reconfigure geotrek-admin

The basic configuration is stored in /opt/geotrek-admin/var/conf/env file, not to be changed manually. This file also contains the PostgreSQL authentification details, if you need to access your Geotrek-admin database.

Custom setting file 

Geotrek-admin advanced configuration is done in /opt/geotrek-admin/var/conf/custom.py file.

The list of all overridable setting and default values can be found there.

After any change in custom.py, run:

sudo service geotrek restart

Sometimes you also have to run:

sudo dpkg-reconfigure -u geotrek-admin

Note

Don’t override the os.getenv() settings as they are managed with Basic configuration.

NGINX configuration 

NGINX configuration is controlled by Geotrek-admin and will be erased at each upgrade. Do not modify /etc/nginx/sites-available/geotrek.conf or /etc/nginx/sites-enable/geotrek.conf. Modify /opt/geotrek-admin/var/conf/nginx.conf.in instead. To update nginx.conf, then run:

sudo dpkg-reconfigure geotrek-admin

Activate SSL / HTTPS 

To activate https, you need firstly to change custom.py and add:

SESSION_COOKIE_SECURE = True
CSRF_COOKIE_SECURE = True

After this, edit nginx.conf.in to add your certificate.

If you generate it with letsencrypt : You can use certbot to add the certificate in your configuration. But you will have to move the configuration automatically added into nginx.conf, to the file nginx.conf.in in /opt/geotrek-admin/var/conf/ directory

You have to move the configuration to the file nginx.conf.in because nginx.conf is automatically changed during command dpkg-reconfigure geotrek-admin.

Mandatory settings 

Spatial reference identifier 

SRID = 2154

Spatial reference identifier of your database. Default 2154 is RGF93 / Lambert-93 - France

It should not be change after any creation of geometries.

Choose wisely with epsg.io for example

Default Structure 

DEFAULT_STRUCTURE_NAME = "GEOTEAM"

Name for your default structure.

This one can be changed, except it’s tricky.

First change the name in the admin (authent/structure),

Stop your instance admin.

Change in the settings

Re-run the server.

Dynamic segmentation 

TREKKING_TOPOLOGY_ENABLED = True

Use dynamic segmentation or not.

Dynamic segmentation is used by default when installing Geotrek-admin.

With this mode, linear objects are built and stored related to paths.

Without this mode, linear geometry of objects is built and stored as an independent geographic object without relation to paths.

So if you want to use Geotrek-admin without dynamic segmentation, set TREKKING_TOPOLOGY_ENABLED to false after installation.

Do not change it again to true after setting it to false.

Translations 

LANGUAGE_CODE = 'fr'

Language of your interface.

MODELTRANSLATION_LANGUAGES = ('en', 'fr', 'it', 'es')

Languages of your project. It will be used to generate fields for translations. (ex: description_fr, description_en)

You won’t be able to change it easily, avoid to add any languages and do not remove any.

Spatial extents 

Boundingbox of your project : x minimum , y minimum , x max, y max:

    4 ^
      |
1     |     3
<-----+----->
      |
      |
    2 v

Default values:

SPATIAL_EXTENT = (105000, 6150000, 1100000, 7150000)

If you extend spatial extent, don’t forget to load a new DEM that covers all the zone. If you shrink spatial extent, be sure there is no element in the removed zone or you will no more be able to see and edit it.

In order to check your configuration of spatial extents, a small tool is available at http://<server_url>/tools/extents/.

Note

Administrator privileges are required.

Users management 

See user management section in usage.

Database users 

It is not safe to use the geotrek user in QGIS, or to give its password to many collaborators.

A wise approach, is to create a read-only user, or with specific permissions.

With pgAdmin, you can create database users like this:

CREATE ROLE lecteur LOGIN;
ALTER USER lecteur PASSWORD 'passfacile';
GRANT CONNECT ON DATABASE geotrekdb TO lecteur;

And give them permissions by schema :

GRANT USAGE ON SCHEMA public TO lecteur;
GRANT USAGE ON SCHEMA geotrek TO lecteur;
GRANT SELECT ON ALL TABLES IN SCHEMA public TO lecteur;
GRANT SELECT ON ALL TABLES IN SCHEMA geotrek TO lecteur;

You can also create groups, etc. See PostgreSQL documentation.
