Переменная среды отсутствует в Django - PullRequest

У меня проблема с моим приложением Geo Django, и я думаю, что оно связано с отсутствующей переменной среды.

У меня следующая ошибка в простом GeoJSONLayerView:

GDALException at /GeoJSONTrialView/9020/
OGR failure.
Request Method: GET
Request URL:    https://realregatta.com/GeoJSONTrialView/9020/
Django Version: 3.0.6
Exception Type: GDALException
Exception Value:    
OGR failure.
Exception Location: /opt/bitnami/python/lib/python3.7/site-packages/django/contrib/gis/gdal/error.py in check_err, line 59
Python Executable:  /opt/bitnami/python/bin/python3
Python Version: 3.7.7

Я нашел обходной путь, добавив переменную среды в представление:

class GeoJSONTrialView(GeoJSONLayerView):
    def get_queryset(self):
        os.environ["PROJ_LIB"]  = "/home/bitnami/stack/postgresql/share/proj"
        context = Trial.objects.filter(id=self.kwargs['pk'])
        return context 

Обратите внимание, что у меня есть переменная, установленная в моем settings.py (и она отображается на странице Django debug cra sh, даже без моего обходного пути):

PROJ_LIB  = "/home/bitnami/stack/postgresql/share/proj"

Traceback:

Не уверен, что делать, чтобы избежать моего обходного пути ...

В итоге я добавил код ниже в свой файл wsgi.py. Может быть, не лучшее место, но оно работает, и я избегаю добавления его в каждое представление:

os.environ["PROJ_LIB"]  = "/home/bitnami/stack/postgresql/share/proj"
