@vary_on_user doesn't work properly if your site uses third-party cookies, since the cache key is created from *all* of the cookies in the request header. This decorator caches pages based on the user ID, so it works reliably.
Yet another authentication by email address. This one is quick and dirty as we are saving email address in both Username and Email fields. For proper way how to deal with it see https://docs.djangoproject.com/en/1.6/topics/auth/customizing/#auth-custom-user
Use this class to authenticate against Usercake (http://usercake.com/) password strings. When importing passwords from Usercake, the database values should be prefixed with "usercake$".
This validator works well with FileField form fields and can validate that an uploaded file has an acceptable mimetype. Place this snippet in your app's `validators.py`. Requirements: This snippet uses [python-magic](https://github.com/ahupp/python-magic). To install: pip install python-magic Usage (in forms.py): from validators import MimetypeValidator class MyForm(forms.Form): file = forms.FileField( allow_empty_file=False, validators=[MimetypeValidator('application/pdf')], help_text="Upload a PDF file" )
Copy this file into `your_app/serializer.py`, and add this to your settings: SERIALIZATION_MODULES = { 'json': 'your_app.serializer', } Now you can dump your models with the classical `dumpdata -n` command and load it with `loaddata` and get support for natural primary keys and not only with foreign keys and many to many fields.
Because {% now "Y"|add:"-2005" %} - etc. doesn't work, you can use the above in your template like: We have {{ 2000|since }} years of experience. or: Serving our customers with passion for more than {% years_since 2005 %} years.
Function that takes a bound form (submitted form) and returns a list of pairs of field label and user chosen value. It takes care of: 1. fields that are not filled out 2. if you want to exclude some fields from the final list 3. ChoiceField (select or radio button) 4. MultipleChoiceField (multi-select or checkboxes) Usage: if form.is_valid(): form_data = get_form_display_data(form, exclude=['captcha']) It's trivial to display the list of pairs in a template: {% for key, value in form_data %} {{ key }}: {{ value }}{% endfor %}
Fixed-point model field based on `IntegerField` and `DecimalField`. Represented as `Decimal` in Python for accurate calculations, stored as integer in the database. Configurable decimal places, defaults to 2.
Provides UUIDField for your models. This version creates very short UUID represenation (21 chars) when the record is added eg. in admin. Generated ids are safe to be used in URLs. You can put represent it in admin as 'readonly_fields=("uuid",)'
This widget is based on django foreign key form field, but its completely dynamic.
This is a class I use instead of the default PayPalPaymentsForm in django-paypal. I wanted to use the Paypal sandbox on my development site and the real Paypal site on my production site. Currently, if you want to output the Paypal form with the sandbox you have to call the sandbox() method on the form, rather than the render() method. Using this class instead of the default PayPalPaymentsForm, you can just set PAYPAL_DEBUG to True in the settings file and the form will take you through to the sandbox instead. Don't forget to set the sandbox merchant account's business email address as PAYPAL_RECEIVER_EMAIL too.
Use this class to authenticate against Drupal 7 password strings. When importing passwords from Drupal, the database values should be prefixed with "drupal$". In contrast to the two present solutions, this class also works with passwords which were imported to Drupal 7 (e.g. from Drupal 6 or phpBB) and with passwords with variable iteration numbers. It is possible to use this class for encoding passwords, but due to questionable design decisions in Drupal (like truncating the non-standard base64 encoded hash at 43 characters) I'd recommend to do this this only if you really need to be able to migrate back to Drupal.
Geocode lookup formats using Nominatim queries.
It's haystack whoosh backend code which involves stemming for specific language in time of indexing. 2 lines was changed comparing to original whoosh backend (StemmingAnalyzer replaced with LanguageAnalyzer for russian language, list of supported languages: [here](https://bitbucket.org/mchaput/whoosh/raw/default/src/whoosh/lang/snowball/__init__.py) )
