I'm implementing a graphql solution using python, graphene and django and I'm getting the following import error:
Result: Failure Exception: ImportError: cannot import name 'force_text' from 'django.utils.encoding'
"/home/site/wwwroot/.python_packages/lib/site-packages/graphene_django/utils/utils.py", line 6, in <module> from django.utils.encoding import force_text
I'm not sure about the versions and whether I need to import an additional module. My requirements.txt is like:
graphene>=2.1,<3
graphene-django>=2.1,<3
graphql-core>=2.1,<3
graphql-relay==2.0.1
django-filter>=2
Has someone had a similar problem and can look at the versions that I use? Thanks
in django 4.0 we dont have force_text
https://docs.djangoproject.com/en/4.0/ref/utils/#module-django.utils.encoding
instead change force_text to force_str
linux:
YOUR_VENV/lib/PYTHON_VERSION/site-packages/graphene_django/utils/utils.py
windows:
YOUR_VENV/lib/site-packages/graphene_django/utils/utils.py
from django.utils.encoding import force_text
to
from django.utils.encoding import force_str
and
def _camelize_django_str(s):
if isinstance(s, Promise):
s = force_text(s)
return to_camel_case(s) if isinstance(s, six.string_types) else s
to
def _camelize_django_str(s):
if isinstance(s, Promise):
s = force_str(s)
return to_camel_case(s) if isinstance(s, six.string_types) else s
adding the following to the requirements.txt solved it:
django<=3
Based on answer given by @Osman.
The problem seems to be occuring with Django-4. Till the PR gets merged, probably this monkeypatching might work (not tested in prod):
import django
from django.utils.encoding import force_str
django.utils.encoding.force_text = force_str
Put this in entryfile. I kept it in settings.py for time being.
"force_text" is removed from Django 4.0:
But graphene_django still uses "force_text" in utils.py.
utils.py:
from django.utils.encoding import force_text # Line 6
s = force_text(s) # Line 29
So you need to replace "force_text" with "force_str" as shown below:
utils.py:
from django.utils.encoding import force_str# Line 6
s = force_str(s) # Line 29
These are the paths to utils.py for Linux and Windows:
Linux:
<your_venv>/lib/<python_version>/site-packages/graphene_django/utils/utils.py
Windows:
<your_venv>/lib/site-packages/graphene_django/utils/utils.py
