How to use password hasher snippet in Django?

[Supermario]

I am trying to move Druap 7 site to django 1.7 without invalidating user 
passwords, and this proved to be daunting.

Fortunately, I have found this 

 SO 
question and this  hashing 
snippet but there is no documentation and as a newbie to django, I have no 
clue how to integrate the snippet into my project.

So greatly appreciate your help about this.

Re: How to use password hasher snippet in Django?

Many thanks for your help Thomas. Indeed I am in the middle of big escape 
effort to get the heck away from Drupal.

I tested your snippet in the shell and DrupalPasswordHasher hashes 
perfectly well there. 

However, when I integrate the hash into my project as per your explanation, 
django-registration module still refuse to authenticate old drupal users. 

Any ideas on how to troubleshoot this?
 
Cheers

Django UnicodeDecodeError at /admin/login/

[Supermario]

I try to implement this  hasher 
in order to be able to authenticate user who are imported from drupal 7. 

So I put the hasher in the settings.py as follows:


PASSWORD_HASHERS = (

'myproj.drupal_hasher.DrupalPasswordHasher', #drupal hasher
 
'django.contrib.auth.hashers.PBKDF2SHA1PasswordHasher',

'django.contrib.auth.hashers.BCryptPasswordHasher',
'django.contrib.auth.hashers.SHA1PasswordHasher',
'django.contrib.auth.hashers.MD5PasswordHasher',
'django.contrib.auth.hashers.CryptPasswordHasher',
 ) 



However it does not authenticate imported users from drupal and for users 
who are created in Django I get:

'ascii' codec can't decode byte 0xcf in position 0: ordinal not in 
range(128)




Here is the trackback:

I am stock on this problem for days so really appreciate your help.

What is the most usable forum app for Django 1.7?

[Supermario]

I am looking for a forum app to integrate into my project which is going to 
be quite high-traffic. So I am looking for a mature forum app. I know there 
are a couple of forum apps listed here:

https://www.djangopackages.com/grids/g/forums/

By 'usable' I mean: 

- Easy to integrate into existing project
- Tested in production environment and showed to be trustworthy
- Has security and performance in mind 
- Has basic functionalities of conventional bulletin-boards 

I have not tried them all, but it appears to me that some are pretty 
out-dated or even abandoned. And some are not production ready yet. 

So I appreciate your hints to choose the best.
