Add a Save and view next button to your admin change form. Put the code at [link](http://www.djangosnippets.org/snippets/2006/) in a file called myapp/templates/admin/myapp/change_form.html Note: Requires Django 1.2.
Pass in a date and you get a humanized fuzzy date diff; e.g. "2 weeks ago" or "in 5 months". The date you pass in can be in the past or future (or even the present, for that matter). The result is rounded, so a date 45 days ago will be "2 months ago", and a date 400 days from now will be "in 1 year". Usage: * `{{ my_date|date_diff }}` will give you a date_diff between `my_date` and `datetime.date.today()` * `{{ my_date|date_diff:another_date }}` will give you a date_diff between `my_date` and `another_date` Make sure to install this as a template tag and call `{% load date_diff %}` in your template; see the [custom template tag docs](http://docs.djangoproject.com/en/dev/howto/custom-template-tags/) if you don't know how to do that.
Just a quick solution to import product data from a excel spreadsheet to satchmo. Supports * hierarchical and multi categories * product attributes * product variations (configurable product, options) * product price * product image
This command, `runtester` will run the test suite whenever files are modified. It takes the apps to test as arguments; if no apps are given the entire test suite is run. Use this command just as `runserver` is used; fire it up in a shell and it does its thing. Copy this snippet into `django/core/management/commands/runtester.py`.
A small function to convert a url to another shortened via the bit.ly service. Requires a username and password in django settings.
Painless serializing
Prevents error flooding on high traffic production sites. Particularly useful to prevent clogging email servers etc. See [discussion](http://groups.google.com/group/django-developers/browse_thread/thread/1dabc9139dd750ca/1d86fdca23189a7d?lnk=gst&q=error#1d86fdca23189a7d) and [closed ticket](http://code.djangoproject.com/ticket/11565). Uses memcache if it can, or falls back to local, in-process memory where unavailable (down, etc). Tweak to your needs using setting ERROR_RATE_LIMIT (seconds). Requires Django 1.3+ or trunk r13981+
This slugify correctly transliterates special characters using the translitcodec package from PyPI. Make sure you've installed http://pypi.python.org/pypi/translitcodec/ before using this.
Using this small helper, you can instanciate your forms in an even DRYer way: form = MyForm(**form_kwargs(request)) if form.is_valid(): #...
This snipped removes a specific fields from the fieldsets. This is very useful to leave a field 'out' in the admin, likewise: def get_fieldsets(self, request, obj=None): fieldsets = super(BlaModelAdmin, self).get_fieldsets(request, obj) if not request.user.has_perm('change_blah'): remove_from_fieldsets(fieldsets, ('blah',))
I work a little with [web.py framework](http://webpy.org/) and I like a lot the view definition. For each view you define a class and in that class you can define two method, GET and POST. If the http request is a GET request the GET method will be called and if http request is a POST request the POST method is called. Then you can define common stuff in another method that could be called inside each method, and you have a class for each view.
look ma, no api! a python method for [fabric](fabfile.org) script to send a message to your [campfire](campfirenow.com) chat room. not really a django script but I didn't know where else to put it. I use it to send a deployment messages to campfire when we deploy new revisions. like the comment mentions, put your api key in ~/.fabricrc. the example api key is garbage so don't waste your time.
Use this abstract model if you want to add "order" to a given model. Once you do, you will get automatic "up" and "down" links for each model row. One problem is that if the user sorts by another row, the up and down links are still there, but now don't make a lot of sense.
Put this in an __init__.py somewhere that will be executed on initialization and all errors will be printed out to stderr. Useful for debugging Facebook apps, javascript calls, etc.
For use in templates: {% if object|classname:"entry" %} ... class="{{ object|classname }}" ... I couldn't find simpler solution for checking weather specific object belongs to specific class name, or just to output object's class name.
