Extended rails flash implementation

This is an extendend version of the Rails Flash implementation by Sean Patrick Hogan that supports different message types. **Setting a flash message:** request.flash.error = 'Item could not be saved' request.flash['error'] = 'Item could not be saved' request.flash['foo'] = 'bar' **Displaying a flash in the view:** <!-- show the error message --> {% if flash.error %}An error occured:{{ flash.error }}{% endif %} <!-- just show the first message found --> {% if flash %}An error occured:{{ flash }}{% endif %} <!-- show all messages --> {% for msg in flash %}{{ msg.type }}: {{ msg.msg }}{% endfor %} Note that it still works with simple strings as well. Feel free to just use it like this: request.flash = "Message" And: {% if flash %}{{ flash }}{% endif %} However, be aware that once you did this, you destroyed the Flash() dict and thus lost the extended functionality. You can use request.flash.clear() to remove all messages.

sort_by_id_sequence

I needed to sort a set of objects (a QuerySet for example) by an externally provided list of IDs - for example: >>> writers = Writer.objects.all() >>> sort_by_id_sequence(writers, [3, 1, 2]) [<Writer id: 3>, <Writer id: 1>, <Writer id: 2>]

To use, drop in to a file called 'debug_middleware.py' on your Python path and add 'debug_middleware.DebugFooter' to your MIDDLEWARE_CLASSES setting.

Date/time util template filters

**Explanations:** - the series "is_*_of" was created 'cos it's easier write: `{% if 10|is_day_of:date and user %}` than write: `{% ifequal date.day 10 %}{% if user %}...` - the series "inc/dec" is not complete, but can the extended to day, hour, minute, etc as you needs. It's util to inc 10 months since 05/31/2006 by example and get a 2007's date :) **Setup:** Insert the snippet into an_app/templatetags/datetimeutils.py. **Use in template:** `{% load datetimeutils %}` and use filters as following: - `{{ 30|is_day_of:a_date_time_variable }}` - `{{ 11|is_month_of:a_date_time_variable }}` - `{{ 2006|is_year_of:a_date_time_variable }}` - `{{ 58|is_minute_of:a_date_time_variable }}` - `{{ 23|is_hour_of:a_date_time_variable }}` - `{{ a_date_time_variable|dec_year:2 }}` - `{{ a_date_time_variable|dec_month:2 }}` - `{{ a_date_time_variable|inc_year:2 }}` - `{{ a_date_time_variable|inc_month:2 }}`
