Add param format=json in every request you want to perform to get JSON responses.
For example: GET /v1/?format=json.
API has self-documented format, so when you request to / (root of the API without any params) you'll get descriptions of all endpoints and can follow them for more descriptions.
You could also use filters when using this API:
/v1/countries/?continents={id}- get countries of the particular continent;/v1/countries/?continents={id},{id},{id}- get countries belongs to several continents.
Example: GET /v1/countries/?continents=an, GET /v1/countries/?continents=an,af
/v1/currencies/?countries={id}- get currencies of the particular country;/v1/currencies/?countries={id},{id},{id}- get currencies belongs to several countries.
Example: GET /v1/currencies/?countries=aq, GET /v1/currencies/?countries=aq,af
/v1/cities/?countries={id}- get cities of the particular country;/v1/cities/?countries={id},{id},{id}- get cities belong to several countries.
Example: GET /v1/cities/?countries=gr, GET /v1/cities/?countries=gr,us
/v1/cities/?regions={id}- get cities of the particular region;/v1/cities/?regions={id},{id},{id}- get cities belong to several regions.
Example: GET /v1/cities/?regions=tx, GET /v1/cities/?countries=tx,il
/v1/cities/?continents={id}- get cities of the particular continent;/v1/cities/?continents={id},{id},{id}- get cities belong to several continents.
Example: GET /v1/cities/?continents=eu, GET /v1/cities/?continents=eu,af
/v1/cities/?slugs={slug}- get cities matching the particular slug, ;/v1/cities/?slugs={slug},{slug},{slug}- get cities matching to several slugs.
Example: GET /v1/cities/?slugs=athens, GET /v1/cities/?slugs=athens,paris
** where slug means the name of the city in lowercase with no accents and instead of spaces, hyphens "-"
You can also define multiple filters on the city endpoint.
Example: GET /v1/cities/?slugs=athens,paris&countries=us®ions=tx
/v1/countrypolygons/?countries={id},{id},{id}
/v1/countrypolygons/?regions={id},{id},{id}
/v1/polygons/?countries={id},{id},{id}
/v1/polygons/?regions={id},{id},{id}
Under virtual env (to create virtualenv, run python3 -m venv env):
source env/bin/activate
export LOCAL_DEV=1
export DEBUG=1
Postgres + PostGIS setup (OS X):
brew install postgis
createuser cosmopolitan
createdb cosmopolitan
psql cosmopolitan
alter user "cosmopolitan" with password '123456';
grant all privileges on database cosmopolitan to cosmopolitan;
CREATE EXTENSION postgis;
If you want your user to have super privileges:
ALTER USER cosmopolitan WITH SUPERUSER;
Tip for local development using (OS X)
Install GDAL binaries for OSX, and add the following to .bash_profile:
GDAL_LIBRARY_PATH="/Library/Frameworks/GDAL.framework/Versions/1.11/GDAL"
GEOS_LIBRARY_PATH="/Library/Frameworks/GEOS.framework/Versions/3/GEOS"
Then add the following to your local Django settings:
# GeoDjango fixes
GDAL_LIBRARY_PATH = os.environ.get('GDAL_LIBRARY_PATH')
GEOS_LIBRARY_PATH = os.environ.get('GEOS_LIBRARY_PATH')
(see https://www.alextomkins.com/2017/08/fixing-gdal-geos-django-macos/ for details)
