Atlas Milieuthema's

Requirements

• Docker-Compose (required)

Developing

Use docker-compose to start a local database.

docker-compose up -d

Run migrate to create the needed database tables

docker-compose exec web python manage.py migrate

Import db data from prod

docker-compose exec database update-db.sh milieuthemas

The API should now be available on http://localhost:8101/milieuthemas/

Accessing the docker database container for view testing:

psql -h localhost -p 5402 -U milieuthemas

Understaing Geoviews

Much of the work in this project is in order to provide geoviews to the map server and the atlas application. In this chapter I will explain how the geoviews are made, and provide a list of steps needed to add a geoview. The geoviews are used by the map server to generate WMS/WMF data and by the geosearch service to spatially find data.

Generating Geoviews

The geoviews are generated using the manage command sync_views. This managment commands collects all the models which meet the geoviews criteria (more later) and generate geoviews for those models. This allows the view to be defiend by the model it is representing, making it very DRY. There are several option to customize the wat the view is generated. This is mostly done by adding certain parameters to the model. For details refer to the ModelViewFieldsMixin class definition.

Steps in adding a Geoview

To make a geoview out of a django model the following steps are needed:

• Make sure the model subclasses the ModelViewFieldsMixin defined in datapunt_generic.generic.mixins. Only subclasses of this class will be used in geoview generation.
• If required, add in the model class any fields name you want excluded to the geo_view_exclude parameter.
• If A URL is needded in the view add the url_path parameter which notes the path part between the domain and the item id
• If a display field is needed ad the display_field parameter. The value should be the (string) name of the field to use as source for the display field

The model should now generate the desired geoview
