I'm learning python + Django by reading 《beginning django e-commerce》， after I have installed django-db-log, when running $python manage.py runserver, there is a problem.

ImportError: No module named hashcompat
You are referring to an outdated manual. Module hashcompat was removed in Django 1.6, as you can read here.
Either install an older Django version (1.5 or previous) or get a more recent textbook. You can also manually fix your code by using Python builtins as advised in the removal notice, but for a beginner can be sort of a hassle :)
I solved it using hashlib. I just added:
try:
from hashlib import sha1 as sha_constructor
except ImportError:
from django.utils.hashcompat import sha_constructor
hashcompat is already deprecated in django 1.6, it is better to use hashlib instead
If you are still following that, the django version used in the book is 1.1 and if you are using higher version of django, then try removing the djangodblog from the app list in the setting.py file. It should work.

I am using Django 1.6. I want to start working site. When you use python manage.py shell get an error:

Tell me what I have a problem. And if it can depend on your database (not sure that Django is connected to the DB - I do not know how to check)?
Added:
Code manag.py:
#!/usr/bin/env python
import os
import sys
if __name__ == "__main__":
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")
from django.core.management import execute_from_command_line
execute_from_command_line(sys.argv)
By the looks of it you're using django-constance.
According to their change log, they haven't supported 1.6 since version 1.1
So either use an older version of that, or better yet - use a supported version of django.
According to the release notes, django.core.cache.caches was introduced in Django 1.7, so this application has never worked with Django 1.6.
If you have a running instance of that application, check which version of Django it actually uses.

No module named MySQLdb
(33 answers)
Closed 6 years ago.
I am trying to deploy a django app on a shared hosting. and i am currently facing issues deploying the app especially the mysql database. I have created the mysql database on the production server. But when trying to run manage.py collectstatic command i am getting the below attached error. I am assuming it has something to do with the mysqldb library.
I don't know how to go about this. Deploying this mysql database
Which ip address should i put on the host part of the db config in the settings.py file. Is it my production server ip address?
Please bear with me i am new to django especially the deployment part. Can't find enough info on the django deployment documentations.
This is the error i am getting on my production server:

As you see in your logs: Error loading MySQLdb module: No module named MySQLdb
My OS is OSX El Capitan.
Versions:
Python 2.7.10
Django 1.9.2
Django-Scarface 3.0
After I install scarface and add it to the installed apps, it gives this error and i can't run my application.

SyntaxError: invalid syntax
After I've search for this error, I think that reason is my python version.
Still I'm not sure, therefore I'm asking to you.
Is there any way to fix this? If the reason is really my Python version, how can i update my python version without damaging my code and everything?
The problem is related to metaclass syntax change in Python 3.x (https://docs.python.org/3/whatsnew/3.0.html?highlight=metaclass#changed-syntax), django-scarface is 3.x oriented. I solved the problem (with Python 2.7.x) changing in platform_strategy.py (Line 38) to this:
class PlatformStrategy():
__metaclass__ = ABCMeta
I submitted a pull request in github project: https://github.com/dreipol/django-scarface/pull/11
In the packaging instructions Python 2.7 is supported https://github.com/dreipol/django-scarface/blob/master/setup.py#L30.
You could run the package tests https://github.com/dreipol/django-scarface/blob/master/scarface/tests.py inside a virtualenv with Python 2.7.10 to see if they pass. If they don't then there's nothing wrong with your code. If they do pass then the problem might not be in the package itself.

I am confused whether i am tying this commands in the correct directory.
any help !!!
Did you install MySQLdb? which is a system library. A quick search on google shows a couple sites you can download this from
One of which is (link pulled from here), another post that addresses this:
http://www.lfd.uci.edu/~gohlke/pythonlibs/#mysql-python
http://sourceforge.net/projects/mysql-python/files/mysql-python/
We would need to see your settings.py file to do more in depth review.
On the surface, it seems like you have not linked it to a database in the settings file. Here is a link that will help you get it installed:
http://decoding.wordpress.com/2012/01/23/how-to-setup-django-and-mysql-python-on-mac-os-x-lion/
(At least on a MAC/Unix. Windows is a different story)
After that, I would just follow any guide on linking the two.
(Some Generic one from a blog)

I'm starting to learn Django and have been following the online tutorial on the Django website.
Everything was working fine and I have a folder called mysite and then sub folders called mysite/ and manage.py like it says in the tutorial: https://docs.djangoproject.com/en/1.5/intro/tutorial01/#creating-a-project
However when I run the command
$ python manage.py runserver
I get this:

Django version 1.5, using settings 'mysite.settings'
Development server is running at http://127.0.0.1:8000/
Quit the server with CONTROL-C.
I've tried to go to http://127.0.0.1:8000/ in my web browser but I just get te error cant connect.
Does anybody know where I am going wrong or what I need to do to rectify the issue?
I'm using Django 1.5 and Python 2.6.1.
According to the Django docs:
Django 1.5 works with any Python version from 2.6.5 to 2.7.
And according to this ticket, I would suggest you to upgrade your Python version. Or, if you can't upgrade it, you have another way, which is presented in the last comment of the ticket:
Use Django 1.4, which supports Python 2.5+
