Re: AttributeError at /auth/users/

[s.alaoui youssef]

class User(AbstractUser):

   .

objects = UserManager()

we have to create User class and specify as objects your UserManager

Good day,
I'm also still learning but I think the name of the function should be

Re: python manage.py commonds: AttributeError: 'PosixPath' object has no attribute 'startswith'

[Julius Chesoni]

You must be a very good Django programmer.

Thank you on behalf of Django community, for such a great answer that even
novices like me are able to understand.

 I had no idea that there were other non default configurations of the
variable BASE_DIR.

Re: python manage.py commonds: AttributeError: 'PosixPath' object has no attribute 'startswith'

[David Nugent]

This error is being triggered by an outdated and badly behaved module
that contains the run_cmdb_worker management command.

Anything that relies on the presence of BASE_DIR in settings is bad
behaviour. This is an entirely arbitrary variable name that might not even
be present in a non-default configuration, and it effectively a "private"
variable.

There are better ways to determine the Django base directory (although
reliance on same is also questionable as it probably assumes a specific
Django layout, which is also poor behaviour).

If you insist on using it, then simply wrap BASE_DIR def with a str() cast,
or use .as_posix() member, i.e.

BASE_DIR = str(Path(__file__).resolve().parent.parent)

This may invalidate other uses in your settings module though, for example:

BASE_DIR / 'someothervalue'

If your change does not trigger an error otherwise, then you are probably
fine.

Regards,
David

psycopg 3 - getting attributeError

[Brian Nabusiu]

[image: attribute_error.png]Hello, 

I wanted to migrate my app to using psycopg 3. However, I got an error that 
insists using psycopg2, even when it was not installed in venv. So I 
decided to ammend some django code as illustrated by the inventor of 
psycopg3. However, 

   1. django complained of not knowing how to import Text from 
   django.db.utils. So I inspected the utils.py, there was class Text. I 
   created one and the error went away. I know I am very much likely wrong 
   doing that
   2. django started but I could not connect to querry relations with 
   attribute error that objects do not have status attribute as shown in the 
   image attached

Anyone using django 4.1, python 3.11.0 and psycopg3 to help?

AttributeError at /invoice/add_invoice/ 'int' object has no attribute '_meta' while using in_bulk

[Kiran Chavan]

I want to convert the model instances into a JSON object and then pass it 
to the HTML file. However, I get an AttributeError at this line:
`data = serializers.serialize("json", Inventory.objects.in_bulk())`

The full `views.py`:

def add_invoice(request):
  form = InvoiceForm(request.POST or None)
  data = serializers.serialize("json", Inventory.objects.in_bulk())
  total_invoices = Invoice.objects.count()
  queryset = Invoice.objects.order_by('-invoice_date')[:6]

  if form.is_valid():
form.save()
messages.success(request, 'Successfully Saved')
return redirect('/invoice/list_invoice')
  context = {
"form": form,
"title": "New Invoice",
"total_invoices": total_invoices,
"queryset": queryset,
"data": data,
  }
return render(request, "entry.html", context)

The Javascript code:

{{ data|json_script:"hello-data" }}

const data = 
JSON.parse(document.getElementById('hello-data').textContent);

document.getElementById('id_line_one').onchange = function(event){
document.getElementById('id_line_one_unit_price').value = 
data[event.target.value].fields.amount;
};



`models.py`:



class Inventory(models.Model):
  product_number = models.IntegerField(primary_key=True)
  product = models.TextField(max_length=3000, default='', blank=True, 
null=True)
  title = models.CharField('Title', max_length=120, default='', 
blank=True, unique=True)
  amount = models.IntegerField('Unit Price', default=0, blank=True, 
null=True)
  
  def __str__(self):
return self.title

How can I pass that JSON object and assign the amount value to the text 
field according to the object selected in the dropdown? Thanks

If you want someone to help you then spend the minimum effort and ask a

That's the least you can do if you expect someone to take the time to

I think the same way.
I will upgrade to 2.2.25 soon. Then I'll open a ticket asap.

Re: AttributeError: 'Values' object has no attribute 'link_base' in building sphinx documentation.

[Jason]

you could raise a bug report on the django tracker 
at https://code.djangoproject.com/query but I'm doubtful that this will 
gain any traction

Those versions of django you specified are very out of date.  1.10 was EOL 
in 2017, 1.11 EOL'd April 2020 and 2.0 EOLd Aug 2018

If you don't have any issues with currently supported versions (2.2, 3.2 
and 4.0),  then its likely that any PRs won't be applied.

AttributeError: 'Values' object has no attribute 'link_base' in building sphinx documentation.

[Sencer Hamarat]

Hello everyone,

If 'sphinx.ext.autodoc' extension enabled in conf.py of sphinx, when I try
to run 'make html' I'm ending up with AttributeError exception:

Exception occurred:
  File /env/lib/python3.6/site-packages/django/contrib/admindocs/utils.py",
line 121, in _role
inliner.document.settings.link_base,
AttributeError: 'Values' object has no attribute 'link_base'

I tried it with combinations of some django and sphinx versions.

Here is the no luck list:
django 1.10, django 1.11 and sphinx 3.5
django 2.0.13 and sphinx 3.5 , sphinx 4.0, sphinx 4.2.0, sphinx 4.3.1

I also opened an issue at sphinx github but they said this has to do with
django admindocs instead of  sphinx.

Is there anybody who has resolved the AttributeError exception thrown while
building documents via sphinx?

Regards,
Sencer HAMARAT

Re: AttributeError: module 'polls.views' has no attribute 'index'

[DJANGO DEVELOPER]

as you mentioned that you're using django 3.2 but your urls.py file is
following the pattern of django 1.7.
use your urls.py this way : path('your polls url here', views.index,
name='index')

Re: AttributeError: module 'polls.views' has no attribute 'index'

[Zain]

Had the same issue. 

Solved, make sure you run each edited python file during the tutorial. 
I guess it needs to update. All I know is this fixed the issue.

We all started out that way.

>From the error message, assuming views it is defined as:

from . import views

or, maybe

from polls import views

it means that python cannot find the function index() in the views module.

Django 3.2 and have exactly the same problems as mentioned above.

path('', views.index, name='index'),
AttributeError: module 'polls.views' has no attribute 'index'

I think this must be wrong. Only User instance have a method 
is_authenticated. Here a example for views:

if request.user.is_authenticated:

Re: AttributeError: object has no attribute 'user' while trying to access instance.user.id

[coolguy]

If i had to stick to your code then i would save the file with 
instance.username. username is available and folder would be readable as 
well.

However, as i mentioned in my last reply and seems you agreed, 
save/register the employee and then have employee upload the picture.

Re: AttributeError: object has no attribute 'user' while trying to access instance.user.id

[Mislav Jurić]

What I can do is first register the employee via a register form, then once 
he logs in ask him/her for the profile picture. *Can I do that this way? *

If I do it this way, I don't have to change my model in any way.

Re: AttributeError: object has no attribute 'user' while trying to access instance.user.id

[coolguy]

not sure about the purpose of showing that example in Django documentation 
while its comments are clear that "object will not have been saved to the 
database yet, so if it uses the default AutoField, *it might not yet have a 
value for its primary key field*."

so that's the reason for having None with file path.

In this approach what i can see is to save the employee first without file 
and then edit and select the file.

I would not use this approach and rather keep it simple as followed:

photo = models.ImageField(upload_to='employee/%Y/%m/%d/', blank=True)

Re: AttributeError: object has no attribute 'user' while trying to access instance.user.id

[coolguy]

May the purpose of showing that example in Django documentation is 
something else. If you read the comments there , there is a potential issue 
that the instance that they suggest to use mostly would have not been 
persisted in the database if AutoField has been used. so there will be 'no' 
id as yet resulting None is being saved with file path.

In this approach what i can see is to save the employee first without file 
and then edit and select the file.

I would not use this approach and rather keep it simple as followed:

photo = models.ImageField(upload_to='employee/%Y/%m/%d/', blank=True)

Re: AttributeError: object has no attribute 'user' while trying to access instance.user.id

[Mislav Jurić]

Hey coolguy,

thanks for responding. After I changed that line as you suggested that 
error is solved, *but when I add the user through the admin interface, I 
get None as the ID* (the folder that gets created in the */media/users* is 
titled *None*). I'm not sure if this is expected behavior.

I haven't added the registration or the login yet, so maybe the ID gets a 
value when someone is actually registering.

Let me know.

Best,
Mislav

Re: AttributeError: object has no attribute 'user' while trying to access instance.user.id

[coolguy]

I wanted to see your model to understand but i realized after my last post 
that you are using "instance.user.id" while your employee instance does not 
have user field. (had to go somewhere urgently) >>> return 
"employees/media/users/{0}/profile_picture.{1}".format(instance.user.id, 
extension)  

change it as follow and remove user from it.
return "employees/media/users/{0}/profile_picture.{1}".format(instance.id 
<http://instance.user.id/>, extension)  

It should work...

AttributeError: object has no attribute 'user' while trying to access instance.user.id

[Mislav Jurić]

Hey guys,

I have the following code in models.py file in one of my apps:

def get_upload_path(instance, filename):
extension = filename.split('.')[-1]
return "employees/media/users/{0}/profile_picture.{1}".format(
instance.user.id, extension)

class Employee(models.Model):
# some attributes here
profile_picture = models.ImageField(upload_to=get_upload_path,
blank=True, null=True)

I am getting the following error when I try to add an Employee via the
admin interface:

AttributeError at /admin/employees/employee/add/

'Employee' object has no attribute 'user'

*I don't know where this error is stemming from.* I took the
get_upload_path function from the official Django FIleField documentation
<https://docs.djangoproject.com/en/3.1/ref/models/fields/#filefield>.

Any ideas as to what is going on here?

Best,
Mislav

Re: Possible Bug? AttributeError: 'HttpResponse' object has no attribute '_resource_closers'

[Tim Allen]

Thanks for the reply, my friend. Unfortunately, no new middleware has been 
added. Some folks have said clearing the Django cache(s) worked, but it 
hasn't for me.

I've long been a mod_wsgi user, but I think it is time to move on to 
gunicorn, so I've started moving in that direction rather than sinking a 
lot more time here.

AttributeError when returning post.title in a comment model

[Ahmed Khairy]

I was working on a comment section for post and was getting an 
AttributeError when I return return '{}-{}'.format(self.post.title, 
str(self.user.username)) in the comment model

I am trying to link users and posts to the comment I am getting the same 
error

Here is the Models.py

class Comment(models.Model):
post = models.ForeignKey(Post, on_delete=models.CASCADE)
user = models.ForeignKey(User, on_delete=models.CASCADE)
content = models.TextField(max_length=160)
timestamp = models.DateTimeField(auto_now_add=True)

def __str__(self):
return '{}-{}'.format(self.post.title, str(self.user.username))

Here is the views.py:

class PostDetailView(DetailView):
model = Post
template_name = "post_detail.html"

def get_context_data(self, *args, **kwargs):
context = super(PostDetailView, self).get_context_data()
post = get_object_or_404(Post, slug=self.kwargs['slug'])
comments = Comment.objects.filter(post=post).order_by('-id')
total_likes = post.total_likes()
liked = False
if post.likes.filter(id=self.request.user.id).exists():
liked = True

if self.request.method == 'POST':
comment_form = CommentForm(self.request.POST or None)
if comment_form.is_valid():
content = self.request.POST.get('content')
comment = Comment.objects.create(
post=post, user=request.user, content=content)
comment.save()
return HttpResponseRedirect("post_detail.html")
else:
comment_form = CommentForm()

context["total_likes"] = total_likes
context["liked"] = liked
context["comments"] = comments
context["comment_form"] = comment_form
return context


class PostCommentCreateView(LoginRequiredMixin, CreateView):

Once again, try to make sense from the error messages. They are actually 
pointing to your problem quite clearly.


In this case, what is your "User" object in your forms.py file?

It is hard to tell since you've only provided some screenshots, but this 
line:


User = get_user_model()

in your views.py file looks very suspicious.

Why are you creating a global User variable?

Did you do the same in forms.py for some reason and why?

Possible Bug? AttributeError: 'HttpResponse' object has no attribute '_resource_closers'

[Tim Allen]

I posted this to Stack Overflow first, thinking it might be a problem with 
`mod_wsgi`, but people using Gunicorn have seen the issue too. Here's a 
link to the question on Stack Overflow:

https://stackoverflow.com/questions/61295971/django-3-0-5-with-mod-wsgi-attributeerror-httpresponse-object-has-no-attribu

Unfortunately, purging my cache hasn't fixed the problem like it did for a 
commenter on the question, so I'm asking here for amplification. Here's the 
text of the post:

I'm getting an error when I deploy Django 3.0.5 under mod_wsgi:  
AttributeError: 
'HttpResponse' object has no attribute '_resource_closers'. I'm running:

   - Python: 3.6.8
   - Django: 3.0.5
   - Apache: 2.4.6
   - mod_wsgi: 4.6.2

Here's the basics of the view causing the error; nothing too exotic (I've 
simplified the code around meetings_struct):


class MeetingsAPIView(MeetingsBaseView):
def get(self, request, *args, **kwargs):
meetings = self.get_meetings()
meetings_struct = []

for meeting in meetings:
meetings_struct.append({
"id": meeting.id,
"name": meeting.title,
"slug": meeting.slug,
})

return HttpResponse(meetings_struct, content_type="application/json")


If I activate the venv and use runserver manually on the server on port 80, 
the same view does not give an error. When the same code and venv are 
running under Apache, here's the error from Apache's logs:

I've rolled back to a previous version that works, running Django 2.2; the 
rest of the stack is the same. This one has me puzzled, as using the same 
deployed code with the same venv that Apache is configured to use works 
fine under runserver, but errors with mod_wsgi. I've tried stopping and 
starting Apache, running the publish process again for a fresh venv and 
code base, and even rebooting the server. The same error occurs, but only 
under Apache / mod_wsgi.


Any ideas? I'm puzzled!

Re: AttributeError with forms

['Amitesh Sahay' via Django users]

I couldn't open the screenshot . But to work with the django forms you need to 
perform below tasks.
1) create model of your choice in models.py.2).  Python manage.py 
makemigrations3) python manage py migrate.4 create a python file called 
forms.py inside your app.5) import your models there ( from .models import 
model_name6) create class to extend forms module.7) in views.py you either need 
to define class based views or function based views. 
I hope that helps.

Re: AttributeError with forms

[Ethem Güner]

It's not strange. You can't access to an attribute of a form class
directly. Remember how do you define the form in a view. You're passing
arguments such as *data=request.POST*. You're trying to access an undefined
attribute. Because It's a form class and needs input.

Try to print *t.__dict__  *you'll get a dictionary of that class. But If
you really need to access to the attribute like this, use* t['date']*

Re: AttributeError with forms

[Phako Perez]

In addition, you must define your model in models.py

And to get this attributes on your views.py from a post request, you could use 
like {{ form.attribute }}

Re: AttributeError

[Phako Perez]

I think issue is how you are trying to access the attribute
This is a form and must be accessed through a post call.

Can you share your html form???

It's hard to guess since you don't show where your User class comes
from, but it doesn't seem like its inheriting from the Django model class.

The error message is quite clear. Look at your User model.

Btw. just a hint: please try to "return early". It is quite difficult to
see which else branches are connected to which if statements in the code
following the one throwing the exception.

Kind regards,

Kasper Laudrup

Hi, 

Can't the error be resolved ? Still, if error has to occur then you can put 
conditions instead of try blocks for better functioning.

AttributeError: 'NoneType' object has no attribute 'app_name'

[Sencer Hamarat]

Hello, 

The project I'm working on has it's custom template context_processor.
And when unavailable URL request arrives to Django (Eg. "/wp-login.php"), 
the context_processor is throwing AttributeError.

Which way should I use to prevent from context processor from throwing 
errors?
Is it ok to wrapping return with try block and returning empty dictionary 
if AttributeError raised?

def resolver_context_processor(request):
return {
'app_name': request.resolver_match.app_name,
'namespace': request.resolver_match.namespace,
'url_name': request.resolver_match.url_name
}

Re: AttributeError 'QuerySet' object has no attribute 'expenses'

[Kean]

Thanks,

I updated the view, and now I am getting syntax error.
Please see below.

views.py

def projectdetail(request):
project = Project.objects.all()
return render(request, 'busprojectdetail.html', {'project': project, 
'expense_list': project.expenses.all()})

projectDetails = Project.objects.select_related(Project).values(select 
column).all()

please advise how to correct?

Best,

Kean

Re: AttributeError 'QuerySet' object has no attribute 'expenses'

[Bhoopesh sisoudiya]

def projectdetail(request):
project = Project.objects.all()
return render(request, 'busprojectdetail.html', {'project': project,
'expense_list': project.expenses.all()})

According to me by this archive you want expense details of each project

Then you write

projectDetails = Project.objects.select_related(your foreign key).values
(select column).all()

Thanks

Re: AttributeError 'QuerySet' object has no attribute 'expenses'

[Kean]

Hi,

please ignore the manager it is just a naming convention ignore, it if for me 
to identify tables, if i have 50 table, I want to be able to know which model 
is holding which object information and for what I need it.

Please use below, I have removed the # information to reduce confusion.

models.py

class Project(models.Model):
name = models.CharField(max_length=100)
budget = IntegerField()

def save(self, *args, **kwargs):
self.name
super(Project, self).save(*args, **kwargs)

class Category(models.Model):
project = models.ForeignKey(
Project, on_delete=models.CASCADE)
name = models.CharField(max_length=150)

class Expense(models.Model):
project = models.ForeignKey(
Project, on_delete=models.CASCADE, related_name='expenses')
title = models.CharField(max_length=100)
amount = models.DecimalField(max_digits=8, decimal_places=2)
category = models.ForeignKey(Category, on_delete=models.CASCADE)

Re: AttributeError 'QuerySet' object has no attribute 'expenses'

[Kean]

Hi Bhoopesh
Thanks for this, please can you put it into the context of my specific model 
setup, so I get it right and understand.
This will be easier for me as this approach is causing me some other errors, 
when i try to apply it.

Best wishes,

Re: AttributeError 'QuerySet' object has no attribute 'expenses'

[Bhoopesh sisoudiya]

Hi Kean,

 Write manager like this ,I give you reference

from django.db import models
 # First, define the Manager subclass.
class BhoopeshBookManager(models.Manager):
   def get_queryset(self):
return super(BhoopeshBookManager,
self).get_queryset().filter(author='Bhoopesh')

# Then hook it into the Book model explicitly. class Book(models.Model):
title = models.CharField(max_length=100)
author = models.CharField(max_length=50)
 # ...
objects = models.Manager()
 # The default manager.

bhoopesh_objects = BhoopeshBookManager()
 # The Bhoopesh-specific manager.


Book.bhoopesh_objects.all() # use manager


Thanks
Bhoopesh Kumar

Re: AttributeError 'QuerySet' object has no attribute 'expenses'

[Kean]

Hi, 

Thanks for the help.

The header for each model is # out, so is not read when the code parsed, it is 
just to help me identify the models.
I only have 3 models Project, Category and Expense.

Best wishes,

Kean

Re: AttributeError 'QuerySet' object has no attribute '_meta'

[Kean Dumba]

Ok thanks is there a way to call all objects, as this is more user friendly
and efficient when potentially editing many object fields?

You can't pass *all* the objects to the form. You have to get the specific one 
you want to edit and pass that as the instance.

AttributeError 'QuerySet' object has no attribute '_meta'

[Kean]

Hi,

New to Django but trying to stick with it.

I have created a model form, which creates ok.

I am trying to edit records. I have the following, but keep getting the 
QuerySet object has no attribute '_meta' in the browser.

my views.py

def editbusiness(request):
data = models.Businessownercreate.objects.all() 
if request.method == "POST": 
form = forms.Businessownercreate(request.POST, instance=data)
if form.is_valid():
form.save()
return redirect("accounts:editremovebusiness")
else: 
form = forms.Businessownercreate(instance=data)
return render(request, 'editbusiness.html', context={ 'form':form })

my forms.py 

class Businessownercreate(forms.ModelForm):
class Meta:
model = Businessownercreate
fields = [ "Creator", "Micro_Small_Medium", "Business_Name", 
"Owner_Firstname", 
"Owner_Surname", "Companies_House_Number", "Address_Line_1", 
"Address_Line_2",
"Town", "City", "County", "Postcode", "Email", "Phone", "Mobile" ]

I'm have defined the meta, so i can't see why the query cant return the 
objects from the model to the form in this instance.

Please can anyone advise or help?

Best,

K

Re: Getting AttributeError: module 'asyncio' has no attribute '_get_running_loop'

The bug was only on Python 3.5. It's possible the other system was 3.6 or
3.7?

Re: Getting AttributeError: module 'asyncio' has no attribute '_get_running_loop'

[Andrew Godwin]

Hi Rohit,

This is my fault - we made a change in the "asgiref" library that
inadvertently removed Python 3.5 support. Channels still needs to support
it (even though Django doesn't).

If you update to asgiref 3.1.4, which I've just released, that should fix
the issue.

Getting AttributeError: module 'asyncio' has no attribute '_get_running_loop'

[Rohit Chopra]

Hi All,

I am using channels to implement WebSockets.
I am trying to send data through WebSockets from *post_save *django signal.
Below is my code.

**signals.py**


@receiver(post_save, sender=CheckIn)
def send_data_on_save(sender, instance, **kwargs):
channel_layer = get_channel_layer()
stats = get_stats()
async_to_sync(channel_layer.group_send)(
'dashboard',
{
'type': 'send_data',
'message': stats
}
)


analytics = get_analytics()
async_to_sync(channel_layer.group_send)(
'analytic',
{
'type': 'send_data',
'message': analytics
}
)



**consumers.py**


class DashboardConsumer(WebsocketConsumer):
def connect(self):
self.room_group_name = 'dashboard'


# Join room group
async_to_sync(self.channel_layer.group_add)(
self.room_group_name,
self.channel_name
)


self.accept()


def disconnect(self, close_code):
# Leave room group
async_to_sync(self.channel_layer.group_discard)(
self.room_group_name,
self.channel_name
)


# Receive message from WebSocket
def receive(self, text_data):
text_data_json = json.loads(text_data)
message = text_data_json['message']


# Send message to room group
async_to_sync(self.channel_layer.group_send)(
self.room_group_name,
{
'type': 'send_data',
'message': message
}
)


# Receive message from room group
def send_data(self, event):
message = event['message']


# Send message to WebSocket
self.send(text_data=json.dumps({
'message': message
}))



this same piece of code is working on my local machine(windows) but when i 
am trying to run this code on server(ubuntu 16.04) i am getting bellow 
error:

also when i am sending data normally from
javascript  .send()


function it is working normally on server but when post_save signal is 
called then only i get this error on server. this is working fine on my 
local system.
I tried removing *async_to_sync *from signals then it is not giving error 
but it is not transmitting data through web socket.
then it is giving:

./check_in/signals.py:47: RuntimeWarning: Coroutine
'RedisChannelLayer.group_send' was never 

AttributeError: type object 'NHTTrainerInline' has no attribute '_meta'

Re: Django 1.11: AttributeError: 'module' object has no attribute 'setup_environ'

[Chi Shiek]

Also failing in local dev_appserver. It seemed to work for a very short 
time (couple of queries) and then it stopped with the same error. 
Gave up and reverting back to 1.4 (which is what app engine seems to 
recommend - 1.4 or 1.11).

Re: Django 1.11: AttributeError: 'module' object has no attribute 'setup_environ'

[Chi Shiek]

Managed to fix it by loading Django as a separate library...
These are the things I had to do...
Used following link to create a libs directory and install django in it 
(via pip - instructions on the page) - also followed the instructions on 
this page for creating a appengine_config.py 

https://cloud.google.com/appengine/docs/standard/python/tools/using-libraries-python-27

Removed django from my app.yaml
libraries:
- name: django
  version: "1.11"

commented out these lines from my main.py
#os.environ.setdefault("DJANGO_SETTINGS_MODULE", "core.settings")
#from django.conf import settings

seems I had this in my app.yaml already
env_variables:
  DJANGO_SETTINGS_MODULE: 'core.settings'

That's about it...oh - also removed the changes I made to...

/home/cshiek/Programs/google-cloud-sdk-1.9.83/platform/
google_appengine/google/appengine/ext/django/main.py

Haven't deployed it yet - but at least the dev_appserver is now running 
properly.

Django 1.11: AttributeError: 'module' object has no attribute 'setup_environ'

[Chi Shiek]

This is related to a bug I raised against app engine while tying to migrate 
from django 1.5 to 1.11.

The issue is I have an app running on app engine using django 1.5.
Recently I was making a number of major updates to the app and decided to 
convert to django 1.11 as part of that update.

Everything seemed to work fine on my local dev_appserver, but when I 
deployed it to app engine, it threw an error similar to this...

ERROR2019-02-28 19:01:49,710 wsgi.py:263]

line 82, in 
management.setup_environ(settings, original_settings_path=settings_path)
AttributeError: 'module' object has no attribute 'setup_environ'


I downloaded the app back to my local development server and built a clean 
python environment using only the exact modules I needed - and then I saw 
the same setup_environ error.
The module indicated has the following code which is throwing the error.

try:
  settings = __import__(settings_path)
  management.setup_environ(settings, original_settings_path=settings_path)
except ImportError:
pass

I changed the code to 
try:
  settings = __import__(settings_path)
  management.setup_environ(settings, original_settings_path=settings_path)
except AttributeError:
  django.setup()
except ImportError:
pass

And everything works fine.
My problem is that the changed module appears to be inside the 
google-cloud-sdk and therefore I cannot change it in production.

My app.yaml point to django 1.11

I've searched the net and no one seems to have encountered this problem 
before...there is a lot about setup_environ, but nothing that addresses 
this particular issue.

I even raised a ticket against app engine 
(https://issuetracker.google.com/issues/124539522) but received a reply 
that it was a django problem.

Question is - has anyone else come across this problem in the app engine 
environment - and how did you resolve it?

Thanks!
/Chi
