Fuzzy Time of Day

This filter will display the time as word(s) indicating roughly the time of day ("Morning", "Afternoon", "Evening", etc). For example, the following template snippet: Posted in the {{ post.date|fuzzy_time }} of {{ post.date|date:"F j, Y"} }}. will result in the following (assuming `post.date == datetime.datetime(2007, 6, 13, 20, 57, 55, 765000)`): Posted in the evening of June 13, 2007. The terms used and breakpoints (hours only) can be rather arbitrary so you may want to adjust them to your liking. See the docs for [bisect][] for help in understanding the code. Just remember you should have one less breakpoint than periods and the first breakpoint falls at the end of the first period. The idea was inspired by [Dunstan Orchard][1], although the code is *very* different (php case statement). He uses quite a bit more periods in a day, so you might want to take a look.

Send information mails to related staff members.

You can use this method to send information mails to the related staff members about section specific site activity. All users which explicitly permitted to 'change' given object will be informed about activity. If you defined get_absolute_url in your model then you can simply use it like this; ` obj=form.save() mail2perm(obj) ` Or you can define your custom urls ; ` from util.mail2perm import mail2perm,domain reply=get_object_or_404(Reply,user=request.user,pk=id) mail2perm(reply,url='http://%s/admin/support/show/?id=%s'%(domain,reply.id)) `

Simple solution for model schema evolution / database changelog

This is a very simple approach to "schema evolution" (Not sure if you can even call it so) - I use it for my project: [SCT](http://sct.sphene.net) and it seems to work quite nicely. The idea is, that if you add or change your models, you add a 'changelog' attribute to your class which defines the SQL queries required to update your models. Of course this only works for one database type... An example 'syncdb' call if a new changelog entry was detected: kahless@localhost ~/dev/python-new/sphenecommunity/sphenecommunity $ ./manage.py syncdb Executing module body. 2007-06-16 00: SQL Statement: ALTER TABLE "sphboard_post" ADD markup varchar(250) NULL Detected changes - Do you want to execute SQL Statements ? (yes,no): So if the SQL statement won't work with the database the user is currently running, he at least knows exactly what he is expected to change in his models. and he can stop automatic execution by simply entering 'no' here.

linebreaksli template filter

This template filter will split a string of text on newlines and return a string of <li></li>s with a newline before every line. This is handy for taking a paragraph of text and making an <ol> or <ul> from its lines. Don't forget to register your filter with the template library first or the filter won't work.

Table

This is rough code that will allow you to create a table using a sequence. It is based on the for loop tag in django template. It works basically the same except that certain variables are set based on what cell is being rendered. The tag itself does not output any html at all. This allows for simple code and very flexible creation of nice tables/grids. Enjoy

Integrating Django with ToofPy

[ToofPy](http://pyds.muensterland.org/wiki/toolserver.html) is a python server that supports WSGI so you can integrate Django with it via the WSGI handler. There is already some default Django integration in the source, but it looked really hacked up with many `if hasdjango:` lines all over the place and hardcoded URLs. A really simple solution is to create a Tool for wrapping around Django. That is what the above file does. So I removed most of the hardcoded django lines and created the tool above. ToofPy dynamically loads tools based on paths on the filesystem, so you'll need to put the file above in the WSGI folder path. Or, if you want to pre-integrate, import the file in the _initops function of WSGIMainTool just after the code to scan the directory.

autocompleter with database query

This is an improvement of snippet 253 in that it supports database queries. Implementing autocompletion for foreign keys takes a few steps: 1) Put the snippet above into <app>/widgets/autocomplete.py. 2) Create a view of your foreign key model (here: Donator) in <app>/donator/views.py: from models import Donator from widgets.autocomplete import autocomplete_response def autocomplete(request): return autocomplete_response( request.REQUEST['text'], Donator, ( 'line_1', 'line_2', 'line_3', 'line_4', 'line_5', 'line_6', 'line_7', 'line_8', '^zip_code', 'location' ) ) This view returns the autocompletion result by searching the fields in the tuple. Each word from the form field must appear at least in one database field. 3) Create a URLconf that points to this new view. 4) In the form where you need the autocompletion, define the widget of the foreign key field as an instance of AutoCompleteField: from widget.autocomplete import AutoCompleteField field.widget = AutoCompleteField( url='/donator/autocomplete/'), options={'minChars': 3} ) The url parameter is the URL connected to the view in step 3), the options dict is passed on to the Ajax.Autocompleter JavaScript object.
