pyramid_oereb, extension for pyramid web frame work to provide a basic server part for the oereb project
Project description
pyramid_oereb is an open-source implementation of the server side part for the swiss “Cadastre of Public-law Restrictions on landownership” (PLR-cadastre).
It is written in Python and designed as a plugin for the Pyramid Web Framework. This allows pyramid_oereb to be included in any Pyramid web application.
Please refer to the documentation for detailed information and instructions for installation and configuration.
If you are interested in contributing or extending the project, take a look at the contribution page.
Local testing for versions V1
Run dev server
Following packages are required: python3-dev libgeos-dev python3-venv postgresql-client libpq-dev
Clone project:
git clone git@github.com:openoereb/pyramid_oereb.git
cd pyramid_oerebThe information for the connection to the main database, the print service and the statistics functionality database has to be provided in a .env file (not committed, copy sample.env and edit it if necessary):
cp sample.env .envRun:
make serveJSON reduced extract is accessible at: http://localhost:6543/oereb/extract/reduced/json/CH113928077734.
When running in to issues installing libpq-dev :
The following packages have unmet dependencies:
libpq-dev : Depends: libpq5 (= 10.12-0ubuntu0.18.04.1) but 12.3-1.pgdg18.04+1 is to be installedTry to install a specific version (adapt the version to your requirement):
sudo apt install libpq5=10.12-0ubuntu0.18.04.1Run tests
To check your code, run make checks. It will run style checks and tests. It’s also possible to run sub-target independently:
make checks-style to run only style-related checks (linting).
make tests to run tests. Python 3.7 is used by default. But you can run tests with another version by running: PYTHON_TEST_VERSION=python3.x make tests. You can also set this variable in the Makefile.
PYTEST_OPTS="-k test_name" make test to run a specific test
After running tests, the coverage is available in the folder coverage_report.
Use Oereblex data model
To test the application with the Oereblex data model, adapt the configuration files pyramid_oereb_standard.yml.mako and docker/config.yml.tmpl. See this example with the theme forest_perimeters:
source:
# Standard data model
#class: pyramid_oereb.standard.sources.plr.DatabaseSource
# Oereblex data model
class: pyramid_oereb.contrib.sources.plr_oereblex.DatabaseOEREBlexSource
params:
db_connection: *main_db_connection
# Standard data model
#models: pyramid_oereb.standard.models.forest_perimeters
# Oereblex data model
models: pyramid_oereb.contrib.models.oereblex.forest_perimetersThe sample data is in sample_data/oereblex.
Run the application:
USE_OEREBLEX=TRUE make serveJSON reduced extract is accessible at: http://localhost:6544/oereb/extract/reduced/json/CH113928077734. This will do a call to the Oereblex service defined in the configuration file, and the success of the call will depend on the external service being available, and the geolink id being used in the sample data still existing on the external system.
It is possible to run this instance in parallel to the instance which uses the standard database. For this, one should create a second clone of the project.
If testing make serve with another theme than forest_perimeters, changes will be necessary in the directory sample_data/oereblex/: first remove the symbolic link corresponding to this theme, then create a directory and add JSON data files into it. In comparison to the data from the standard model, a new attribute geolink is required in public_law_restriction.json, which should correspond to an existing geolink in the Oereblex server defined in the configuration (see sample_data/oereblex/forest_perimeters for example files).
Dev environment (V2)
pyramid_oereb can be run with docker-compose or directly on the host. The application requires a running database.
The Docker composition consists of the service oereb-server (the container in which the application is to be started) and the service oereb-db (which hosts the database). To run pyramid_oereb with docker-compose, see section “General workflow (in Docker)”.
To run the server directly on the host, you need to be using a Linux system with all the dependencies installed. In this case, you should use an already existing database. For details see section “General worfklow (local shell)”.
Database connection
For the database connection, the following environment variables must be set (if not using the default parameters):
# the db-server username
PGUSER
# the db-server password
PGPASSWORD
# the db-server host
PGHOST
# the database in the db-server
PGDATABASE
# the port on which the db-server is listening
PGPORTIf these are not provided, the default values found in the Makefile will be used.
NB: if these environment variables are set in the host environment, they will also be used in the docker-compose composition.
General workflow (in Docker)
Run the composition with docker-compose up -d
You can check whether the containers started properly with docker-compose ps
Connect to the server container with docker-compose exec oereb-server zsh
Start the server in development mode with make serve-dev
The sample data extract should be available at http://localhost:6543/oereb/extract/json?EGRID=CH113928077734
BONUS: If you use an IDE like VSCode you can attach it to the running container to have convenient features like autocomplete or code inspection
NB: Alternatively, start the server from your local shell with docker-compose exec oereb-server make serve-dev
Clean up after work
It is recommended to stop your composition when you stop working:
docker-compose downUpdate Dockerfile
If you need to change something inside the Dockerfile you need to rebuild the oereb-server image. So after your change, stop the docker composition and rebuild it:
docker-compose down
docker-compose buildGeneral workflow (local shell)
These instructions are sufficient only if you have all dependencies locally available (python3-dev libgeos-dev python3-venv postgresql-client libpq-dev etc.) and in the right versions. Otherwise this might lead to strange behaviors.
In a local shell in the project path, start the server in development mode with make serve-dev
The sample data extract should be available at http://localhost:6543/oereb/extract/json?EGRID=CH113928077734
Useful make targets
Run the make targets found in the Makefile either in the oereb-server container (if using docker-compose) or in your local shell (if running the server locally). Some useful targets:
make serve-dev to run the application
make test to run the application tests
make clean to empty the database
make clean-all to empty the database, uninstall the application and the virtual env and clear the rendered configuration files
If necessary the application is re-installed and the database is filled when running make serve-dev again.
Using MapFish-Print
To be able to test the OEREB static extract (pdf), you need to run pyramid_oereb with docker-compose and to have a running instance of pyramid_oereb_mfp. The Docker network print-network is also required and can be created with:
docker network create print-networkThe sample static extract should then be available at http://localhost:6543/oereb/extract/pdf?EGRID=CH113928077734
