This is what I am trying to run. When I run the server and run these lines within a view and then return an HttpResponse, then everything goes fine. However when I run python manage.py shell and then try to run through these lines then I get an error:
product = Product.objects.get(pk=4)
template = loader.get_template('weekly-email.html')
user = User.objects.get(pk=1)
body = template.render(Context({
'user': user,
'product': product,
}))
Output:

Also, I am using django 1.8.
This is a known issue and will be fixed in 1.8.1.
Meanwhile, you can manually activate a language in your shell to fix it:
from django.utils.translation import activate
activate('en') # or any language code
UPDATE: 1.8.1 has been released, so the best solution is to upgrade to the latest 1.8.x version.

As this is my first question in SO, pardon me if there's any mistake :)
Thanks in advance :)
The error occurred because of the htmlcov folder which was generated while running the coverage script.
Removed that folder and executed the following commands to generate the '.po' files.
./manage.py makemessages -l fi
and the following command to generate the '.mo' files.
./manage.py compilemessages

I'm using python-3.4, django-1.7.4 and for the SQL connection mysql-connector-python-2.0.2. For this project I've created a virtual environment with the python 3 venv. I host this project on github: https://github.com/pkreker/p_kreker
Thank you in advance!

Since the bug headline does not specify "Django", I expect a number of Python 3 newbies will end up here. Note that the hashable/immutable counterpart to "bytearray" is the type "bytes".
>>> b1 = bytearray([1, 2, 3])
>>> s = set()
>>> s.add(b1)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'bytearray'
>>> b2 = bytes(b1)
>>> b2
b'\x01\x02\x03'
>>> s.add(b2)

I think this is likely to be a bug in mysql-connector-python - does it support Django 1.7.4? Your code works fine if you run it with sqlite.
If the project is on an older version of Django for example 1.11.16, try explicit decoding by calling the method .decode("utf-8") in introspection.py file.
if django.VERSION >= (1, 8):
return [
TableInfo(row[0].decode("utf-8"), {'BASE TABLE': 't', 'VIEW': 'v'}.get(row[1].decode("utf-8")))
for row in cursor.fetchall()
]
else:
return [row[0] for row in cursor.fetchall()]
introspection.py file path:
C:\Python27\Lib\site-packages\mysql\connector\django\introspection.py
method prototype:
def get_table_list(self, cursor):
I had this error today. I had created my db as utf8_bin collation, which I assume was the reason for it. Dropped the DB, re-created with utf8_general_ci, ran migrations, and it worked fine.
ive got a problem here. When i try to "collectstatic" from manage.py it just kicks me off with following error:

At least my extendes urls.py

Iam very sure that its the double backslash in the path (at the end of the error code).
I hope you can help me to fix my problem.
THANKS!!!

What does your Directory structure actually look like?
I doubt that 'C:\Users\mszalewski\PycharmProjects\static\static' is the folder you're intending to use for the Project specific static files.
My guess is that you want to change
os.path.join(os.path.dirname(BASE_DIR), "static", "static").replace('\\', '/')
to
os.path.join(BASE_DIR, "static", "static")
Or something very similar. And don't worry about the '\\' and '/'. Python will actually get along just fine with some very odd combinations of them in the same path.
Because you are in a virtual directory (assuming you've already activated the virtual env like so : source <*Scripts* or *bin*>/activate), the path that STATIC_ROOT and STATICFILES_DIRS expect are different.
1) STATIC_ROOT is expecting the location of the static files on your local machine (whether that be the cloud server you are serving these files on the computer that you are developing on) --> i.e. something like STATIC_ROOT = 'C:/Users/<user>/Desktop/django_env_folder/mysite/static/mysite'
2) STATICFILES_DIRS on the other hand is expecting the virtual_env path (remember, when you activate your virtual env using the command above, the paths that os.<method>() requires are different (do some debugging to see, try running os.listdir('C:/....') and you will notice different results than expected. SO try something like this for STATICFILES_DIRS --> STATICFILES_DIRS = [
'mysite/static/mysite',
]
** This solution definitely works when serving on localhost, make sure Debug = True in your settings.py.
