This is a replacement for Django's built-in ImageField. It uses the Google AppEngine image APIs in order to validate. Notes: 1. Validation of the field counts against your App Engine transformations quota. 2. This code assumes you're only using the in-memory file upload handler. None of the other stock handlers work well on App Engine; you should probably disable them.
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',))
This is a hack to get HTML 5 to work for Firefox 2. It Sends the xhtml content-type to all Gecko based browsers where version is less than 1.9, or "rv:1.9pre" or "rv:1.9a" or "rv:1.9bx" where x is less than 5. I created this hack based on the information I found on this site, http://html5doctor.com/how-to-get-html5-working-in-ie-and-firefox-2/. Just put this code in one of your middleware files (i.e. mysite/middleware.py) and then add it in your MIDDLEWARE_CLASSES in your settings.py. Example: MIDDLEWARE_CLASSES = ( ... 'mysite.middleware.HTML5Firefox2Hack', ... )
Calls a view by request.method value. To use this dispatcher write your urls.py like this: urlpatterns = pattern('', url(r'^foo/$', dispatch(head=callable1, get=callable2, delete=callable3)), ) If `request.method` is equal to head, `callable1` will be called as your usual view function; if it is `get`, `callable2` will be called; et cetera. If the method specified in request.method is not one handled by `dispatch(..)`, `HttpResponseNotAllowed` is returned.
Have you always been annoyed by how you set up this elaborate big database schema and weren't able to have **ON DELETE CASCADE ON UPDATE CASCADE** in dbshell? This solves the problem; create the two files and and empty *__init__.py* and put them somewhere in your path. Then say DATABASE_ENGINE='postgresql_psycopg2_cascade' in settings. Really I'd like this to be in the ForeignKey object, were it upstream Django or an own version of it, but it doesn't seem possible. Ideas on how to make this configurable are more than welcome! Props go out to Ari Flinkman for the inspiration to do this!
This is a really simple snippet , but is not documented well ... Whit this , you can limit the output of one field in 25 characters before you test that is equal or over 30 characters! Note that the snippet cut the text and add three points at the end (...) Enjoy!
I don't understand why the cache is accumulated between the tests. I thought one of the axioms of unit testing is that the tests should not affect each other. Couldn't find anything that explains why it's done this way but it seems a bit strange. Anybody know if there's a reason or is this a reason for me to upload a patch to Django code?
A bit cleaner syntax for method attribute assignment; used in models for 'short_description'. >from mysite.polls.models import Poll >poll = Poll.objects.get(pk=1) >poll.was_published_today.short_description >>>'Published today?'
UPDATE: 'ORDER BY' in de regex is now optional If enabled while coding just keep track of your console output for: <<< WARNING >>> Query execution without ownership clause, called from "process_response" Happy coding Regards, Gerard.
Return a datetime corresponding to date_string, parsed according to format. I had the need for such a thing while working with an API that returned JSON that I fed, via simplejson, directly to a template, and didn't want to change the data structure just for this one piece.
This generic view does the same that 'django.views.generic.simple.redirect_to' does but supports request.GET parameters.
Sometimes you have an uncontrolled amount of text in a horizontally constrained space. The wrappable filter places zero-width breaking spaces into the given text so that it can wrap at any point, as necessary for the containing width. Sometimes better than eliding (chopping long text...) or cropping/scrolling overflow.
application 'someapp' don't have urls.py file, all information about urls placed as decorator for view function PS: Added functools.wraps
It is supposed the aggregation on integer is fast than numeric type in database duo to how they are stored as numeric is represented as string. As money only have 2 decimal place, it can be converted to an Integer despite of its decimal point. The python class decimal.Decimal also has a shortcoming that it is not json serializable(neither cjson nor simplejson). This money field appears as a float number to the front end, so it does not meet the headache as DecimalField. The usage is very simple. In Model: class SomeModel(models.Model): ... income = MoneyField('income') ... Then treat the attribute of the model instance as a normal float type. **Notes** If you try to use aggregation on this field, you have to convert it to float by yourself. Currently I could not find any method to fix this.
This Template Tag computes the font-size of two given arguments and returns a CSS-encoded string like "font-size: XXpx;", which can be used to format the font-size of link. (The minium font-size must be set with CSS.) Requires two arguments: 1. occurrence of the current tag 2. sum of all occurrences It works great for my tag-cloud. [Source of the logarithmic formula](http://www.php.de/php-fortgeschrittene/44928-tag-cloud-algorithmus-fuer-schriftgroessye.html) **Usage** `<a href="http://www.anything.com" {% cloudify variable.occurrence overall. occurrence_sum %} title="anything">any tag</a>`
