AttributeError: function 'initGEOS_r' not found
I get AttributeError: function 'initGEOS_r' not found error while trying to run my server.
I am trying to write a basic Geo Django program
I have Postgres and GEOS also installed
I have also included GEOS and GDAL paths in my settings.py file.
I have tried all possible way to resolve this error but couldn't.
Can Someone Help me out!
I had the same problem this worked for me:
On settings.py write:
GDAL_LIBRARY_PATH = r'C:\OSGeo4W64\bin\gdal204'
GEOS_LIBRARY_PATH = r'C:\OSGeo4W64\bin\geos_c.dll'
PROJ_LIBRARY_PATH = r'C:\OSGeo4W64\share\proj'
On settings.py INSTALLED_APPS code:
'django.contrib.gis',
Add postgis to backend
DATABASES = {
'default': {
'ENGINE': 'django.contrib.gis.db.backends.postgis',
'NAME': 'xxx',
'USER': 'yyy',
'PASSWORD': 'xxx',
'HOST': '',
'PORT': '1234',
}
}
Remember that your models should inherit from
from django.contrib.gis.db import models
I hope this can help you
Same steps as the answer above, but on the M1 Macs, the settings looked like this:
GDAL_LIBRARY_PATH = "/opt/homebrew/lib/libgdal.dylib"
GEOS_LIBRARY_PATH = "/opt/homebrew/lib/libgeos_c.dylib"
(Didn't need PROJ because I'm using "ENGINE": "django.contrib.gis.db.backends.mysql",

I can not run the project, I did what I was told in README.md as directed, but still gives an error.

It's frustrating that I'm a beginner and a rookie, I can't fix it.
And I didn't find the answer on the Internet, I can only try to come here and ask for your help
version:
Django: 3.2.10
drf : 3.11
redis: 3.0.2 （windows release）
my settings:
CACHES = {
'default':{
'BACKEND': 'django_redis.cache.RedisCache',
'LOCATION': 'redis://127.0.0.1:6379/0',## if redis server has passwd，
# "LOCATION": "password#redis://127. 0.0.1:6379",
'OPTIONS': {
'CLIENT_CLASS': 'django_redis.client.DefaultClient',
}
},
}
#
REST_FRAMEWORK_EXTENSIONS = {
'DEFAULT_CACHE_KEY_FUNC':
'rest_framework_extensions.utils.default_cache_key_func'
}
#views.py Like this：
from Users.serializers import UserAddrModelSerializer
from rest_framework_extensions.cache.decorators import cache_response
class Cache_test(APIView,):
permission_classes = []
throttle_classes = (AnonRateThrottle, UserRateThrottle)
#cache_response(timeout=60)
def get(self, request, *args, **kwargs):
obj = UserAddress.objects.all()
result = UserAddrModelSerializer(instance=obj, many=True).data
return Response(result)
This particular error is caused by drf-extensions not being compatible yet with Django 3.1+. (drf-extensions is one of the dependencies of your app; also, you say you're using 3.2.10, but 3.2 is still under development; the latest released version as of writing is 3.1.1) I've found a commit to the drf-extensions project on GitHub solving this issue, but that has not found its way yet to a release.
Some of your options:
Check if you really need the dependency, and if not, uninstall it. Depending on your caching needs, simply using Django's built-in caching framework might suffice.
Incorporate the fix in that commit that I linked into your installation of that dependency (i.e. patch your library locally).
Downgrade your Django installation in the meantime to version 3.0 (as a last resort).
I am getting an error in Django. I saw a lot of similar questions but am not able to find a working solution. I think the error is in importing the User model. I am not able to find a solution to this. Basically, it seems that it is not able to get the User model. Please help.

raise ImproperlyConfigured("If set, %s must end with a slash" % name)

How do I deal with it?? please help) Cant post my question, because it asks for more information, but to me there is no additional info
The error says your STATIC_URL value doesn't end with a slash. Checking your settings.py file and make sure it has a slash at the end of the value - a forward slash.
STATIC_URL = '/static/'
STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, "static")
This is exact copy of static in settings.py
