Papyrus provides geospatial extensions for the Pyramid web framework.
Papyrus includes an implementation of the MapFish Protocol. The MapFish Protocol defines a HTTP interface for creating, reading, updating, and deleting (CRUD) geographic objects (a.k.a. features).
Papyrus includes lower-level objects, like the GeoJSON renderer, that may come in handy for your apps even if you don’t need or want MapFish views.
Papyrus can be installed with
$ pip install papyrus
(Installing Papyrus in an isolated
virtualenv is recommended.)
You may want to install
simplejson as well. This dependency is not required
but it provides more functionnalities than the
json module from the
standard library like the possibility to parse float numbers as Decimal.
papyrus can use such options if
simplejson is present.
Most of the time you’ll want to make Papyrus a dependency of your Pyramid
application. For that add
papyrus to the
install_requires list defined
in the Pyramid application
install_requires = [ 'pyramid', 'pyramid_tm', 'SQLAlchemy', 'WebError', 'papyrus' ]
Papyrus is on GitHub: http://github.com/elemoine/papyrus. Fork away. Pull requests are welcome!
Running the tests¶
Papyrus includes unit tests. Most of the time patches should include new tests.
To run the Papyrus tests, in addition to Papyrus and its dependencies the
following packages need to be installed:
For these packages to install correctly, you have to have header files for
GEOS. On Debian-based systems install the
following system packages:
pip and the
dev_requirements.txt file to install these packages in
the virtual environment:
$ pip install -r dev_requirements.txt
To run the tests:
