Setting distinction between development and public server
If your code is under source control and you develop locally and then publish that globally, you might need to modify the settings file after each update to ensure the system paths and database settings are correct. This simple solution helps to distinguish development server from the public server. And you won't need to care about modifying files on the public server anymore. Create a file called `dev_environment.py` in your `site-packages` directory of the development server only (do not put it under source control). Then use the following lines in the beginning of your files, you want to check whether you are in the development environment. try: from dev_environment import * except: is_dev_environment = False Then for example, you can set the database settings according the environment: if is_dev_environment: DATABASE_NAME = "test" DATABASE_USER = "root" DATABASE_PASSWORD = "" else: DATABASE_NAME = "publicproject" DATABASE_USER = "projectuser" DATABASE_PASSWORD = "ahl3379ljkasd"

Url overrides and concurrent site versions
If you want to run multiple versions of a site from the same project IE a staging version and the live one, you need two settings and urlconf files. 1. make separate copies of settings_staging.py and urls_staging.py in the project dir. 2. Change SITE_ID and ROOT_URLCONF in settings_staging.py 3. Make extra include lines in the projects urls_staging.py like the example. 4. Add urls_staging.py to applications where you need extra urls. Make them just like you would normally do urls.py Thanks to ronny for suggesting the double entries in urlconf.

intergrate mako and genshi with django
You can download these files from [here](http://huangyilib.googlecode.com/svn/trunk/mashi_django) Django template, mako, genshi, they are the best three templates in python, aren't they? How to use these files ? [Using Mako in Django](http://fuzzythinker.blogspot.com/2007/04/using-mako-in-django.html) -- by John Leung

create_object and update_object for newforms
create_object and update_project modified to handle newforms (including FileFields). In addition, I have added some extras: 1. extra_fields - this is a dict or callable that contains additional fields to be passed to the form, for example stuff that is in the session. 2. on_success - callback called if form is valid and object created/updated, if this is not set the default behaviour is to send a redirect 3. on_failure - callback called if form is invalid, the default is to redisplay the form. Note that once newforms are finally done these functions are likely to be redundant, as generic views will be updated to use the newforms API, so use with caution.

Win32 Read Registry Tag
Sometimes you need to grab information from the registry. This will only work if you have admin rights on the box you're querying.

Upload a zip file with newforms
This is a minor modification to [Upload a file using newforms](http://www.djangosnippets.org/snippets/95/) as posted by [mboersma](http://www.djangosnippets.org/snippets/95/). I altered the ZipUploadForm by removing lines 33 - 34: if 'zip_file' in self.clean_data: zip_file = self.clean_data['zip_file'] and adding a return statement to clean_zipfile, which returns the validated zip file. I also added the line: zip_file.clean = clean_zipfile so that when the full_clean() in called on the form, clean_zipfile will automatically run. All other code (the view & template) remain the same. ** Disclaimer ** I'm not *that* familiar with newforms, so please forgive me if some the explanation as to why this works is incorrect ;) Who knows, maybe the first guy had it right.

Akismet Webservice
A short little bit of code to test for comment spam against Akimet. Use: a = Akismet('<AkismetKey>', 'http://sneeu.com/blog/') a.verify_key() print a.comment_check( comment_author='...', comment_author_email='[email protected]', user_ip='10.0.0.1', comment_content="""Comment content!""" )

Cache Any Function
A decorator similar to `cache_page`, which will cache any function for any amount of time using the Django cache API. I use this to cache API calls to remote services like Flickr in my view, to prevent having to hit their servers on every request. I posted a sample function which uses the [delicious API](http://www.djangosnippets.org/snippets/110/) in the function, also. **Update**: It now also will put in a temporary 'in-process' variable (an instance of `MethodNotFinishedError`) in the cache while the function is processing. This will prevent the cache from calling the method again if it's still processing. This does not affect anything **unless you're using threads**.

Cached Del.icio.us API Calls
This will save your del.icio.us bookmarks in your own database with a Bookmarks model. It depends on several things: 1. `DELICIOUS_USER` and `DELICIOUS_PASS` defined in settings.py 2. [pydelicious](http://code.google.com/p/pydelicious/) installed 3. Any view that uses del.icio.us should call the delicious() function, to update the database. 4. The [cache_function](http://www.djangosnippets.org/snippets/109/) decorator must be available. (I have it in a decorators.py file in my app; if you move it, you need to update the import) 5. The [django-tagging](http://code.google.com/p/django-tagging/) app, although it could be modified to not need this rather easily. Other than all those dependencies, it's actually rather simple. It will call del.icio.us for the 5 most recent posts, and create them if they're not already in the database. Otherwise, it'll check for updates, and change as appropriate. It won't return anything, as it updates the models themselves.

Use pexpect to control manage.py syncdb or anything else
You can read the short blog article that gives a [description of what I was thinking](http://unpythonic.blogspot.com/2007/03/using-pexpect-to-control-django.html) when I attempted this. Note: UNIX only. Sorry!

Unobtrusive comment moderation
**Before using this snippet**, please note that it's largely been superseded by [comment_utils](http://code.google.com/p/django-comment-utils/), which includes a more featureful and extensible version of this system, particularly with respect to additional moderation options and useful things like email notifications of comments. Once upon a time I hacked the copy of `django.contrib.comments` I'm using on my blog, so that I could have comments get set to `is_public=False` if posted more than 30 days after the entry's publication, and to add Akismet spam filtering. I've regretted it ever since, because it's made upgrading my copy of Django a pain. So here's an improved version which doesn't require hacking directly on Django. To use it, you'll need to do a few things: 1. Grab the [Python Akismet module](http://www.voidspace.org.uk/python/modules.shtml#akismet) and install it somewhere on your server. 2. In your settings file, add `AKISMET_API_KEY`, and make sure its value is a valid Akismet key. If you don't have an Akismet key, you can [get one at wordpress.com](http://wordpress.com/api-keys/). 3. Put this code -- both the function and the dispatcher calls -- somewhere in your project that's _guaranteed_ to be imported early (until this code is executed, the moderation function won't be set up to listen for comments posting). To have comments on a certain type of object (say, weblog entries) automatically go into moderation when the object reaches a certain age, define a method on that object's model called `comments_open`, and have it return `False` when comments should be auto-moderated.

Modelaware json serializer
A serializer that handles dicts with querysets and model instances, nice to use if you have a paginator context. paginate_by = 8 paginator = ObjectPaginator(queryset, paginate_by) page = request.GET.get('page', 1) try: page = int(page) object_list = paginator.get_page(page - 1) except (InvalidPage, ValueError): if page == 1 and allow_empty: object_list = [] else: raise Http404 result = { 'object_list' : object_list, 'is_paginated': paginator.pages > 1, 'results_per_page': paginate_by, 'has_next': paginator.has_next_page(page - 1), 'has_previous': paginator.has_previous_page(page - 1), 'page': page, 'next': page + 1, 'previous': page - 1, 'pages': paginator.pages, 'hits' : paginator.hits, } serialize(result, ensure_ascii=False)

Days Since Filter
Very simple filter that returns one of the following by default: 1. \# days ago 2. yesterday 3. today 4. January 01, 2007 Example template code: This thread was started {{ post.date_created|dayssince }}. This thread was started today. E-mail sent: {{ email.date_sent|dayssince|capfirst }} E-mail sent: Yesterday Object created: {{ obj.date_created|dayssince|upper }} Object created: 12 DAYS AGO User's bogus birthday: {{ user.get_profile.bday|dayssince }} User's bogus birthday: April 20, 3030
