DebugFooter middleware with textmate links

a minor remix of simon's debug footer: <http://www.djangosnippets.org/snippets/766/> > Adds a hidden footer to the bottom of every text/html page containing a list of SQL queries executed and templates that were loaded (including their full filesystem path to help debug complex template loading scenarios). This version adds TextMate links : if you are working on your local machine and using TextMate you can click on the template paths and they will be opened in TextMate. This speeds up development time considerably ! also, this works with django 1.0 (simon's version got broke by the 'connect' refactor) update: the view function is now linked > 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.

Model inheritance with content type

Contact is a parent class. Subclasses might be Company, Person, Artist, Label etc. Basic address, email etc. fields can be added to the parent class and all subclasses will have those. Having searched your database for contacts (undifferentiated by class) you then want to reload the chosen object as the subclass that it really is : ``thing.as_leaf_class``

Moving items up/down from the admin interface

Move Items up and down from the admin interface. Like phpBB does it with its forums. An additional select field is added to the admin form. After the model has been saved, a model method is called (with the value of the new field), which handles the reordering. A more detailed description and a screenshot can be found [here](http://blog.vicox.net/2008/09/04/ordering-in-django-10/).

SOAP views with on-demand WSDL generation

Optio's [soaplib](http://trac.optio.webfactional.com/wiki/soaplib) makes it really straightforward to write SOAP web service views by using a decorator to specify types. Plus it's the only Python library, as of today, which is able to generate WSDL documents for your web service. You can test it with a soaplib client: >>> from soaplib.client import make_service_client >>> from foo.views import HelloWorldService >>> client = make_service_client('http://localhost:8000/hello_world/', HelloWorldService()) >>> client.say_hello('John', 2) ['Hello, John', 'Hello, John'] And get an WSDL document: >>> client.server.wsdl('') '<?xml version=\'1.0\' encoding=\'utf-8\' ?><definitions name="HelloWorldService" ... </definitions>'

Automatic stripping textual form fields

Here is a class decorator that allows not to bother with stripping leading and trailing white space from user input provided via forms. This could be a temporary solution for an issue addressed in the ticket [#6362](http://code.djangoproject.com/ticket/6362). The documentation is provided in the form of doctest. The decorator works with `ModelForm`'s just as well as with ordinary forms. Note however that this is not a 100% panacea. Your models still could become malformed if theirs data is obtained from another source, not forms.

syncdata command

A django admin command that takes a fixture and makes the target database the same as that fixture, deleting objects that in the database but not in the fixture, updating objects that are different in the database, and inserting missing ones. Place this code in your_app/management/commands/syncdata.py You will need to use manage.py (not django-admin.py) for Django to recognise custom commands (see http://www.djangoproject.com/documentation/django-admin/#customized-actions). This snippet is the 'loaddata' command with this patch applied: http://code.djangoproject.com/ticket/7159 (with minor tweaks). The intention is that 'dumpdata' on system A followed by 'syncdata' on system B is equivalent to a database copy from A to B. The database structure in A and B must match.

Authentication Against Active Directory (LDAP) over SSL

I had some trouble getting other peoples code to work for AD support, so I wrote my own which authenticates against LDAP and will also use SSL and cert if required. It will also verify that an autheticated user has specific group membership before authorizing. This will also debug to a file, which is really helpful when trying to figure out problems. One thing that really got me when getting python-ldap to work was that you must have "ldap.set_option(ldap.OPT_REFERRALS,0)" set or any ldap search will not work. Also, this will add group permissions to a user.

WithTag Tag

Set a context variable with the returned value by any templatetag. Useful for example in order to use url templatetag inside blocktrans: ` {% withtag url my_app.views.my_view as my_view_url %}` ` {% blocktrans %}` ` Click <a href="{{ my_view_url }}">here</a>` ` {% endblocktrans %}` ` {% endwithtab %}` Or with include templatetag: ` {% withtag include "js_template.js" as js_template %}` ` {{ js_template }}` ` {% endwithtab %}` It works properly with your own custom templatetags.

Modify query string on a url

Modify a query string on a url. The comments in the code should explain sufficiently. String_to_dict, and string_to_list are also useful for templatetags that require variable arguments.

Model manager with row caching

RowCacheManager is a model manager that will try to fetch any 'get' (i.e., single-row) requests from the cache. ModelWithCaching is an abstract base model that does some extra work that you'll probably want if you're using the RowCacheManager. So to use this code, you just need to do two things: First, set objects=RowCacheManager() in your model definition, then inherit from ModelWithCaching if you want the invalidation for free. If you are unusually brave, use the metaclass for ModelWithCaching and you won't even need the "objects=RowCacheManager()" line.

Scan uploaded file for viruses with clamav

A clean_&lt;fieldname&gt;() method in a form subclass as described [here](http://www.djangoproject.com/documentation/newforms/#custom-form-and-field-validation). Scans the field named *file* for viruses. My version of python-clamav does not support scanning of buffers. That is why I go through the hassle of saving the file to a temporary one.

DisplayModelForm

Subclass of the ModelForm which allows to make fields 'display_only'. This means no formfield will be displayed, but a suitable representation. You can make all fields display_only or just a few (or you can use the form as a normal modelform). There are also some extra's to easily set attrs on fields or set help_texts on widgets when using this form. Why ? I made my own set of generic crud views based on newforms, but added a 'display' view to simply display objects, in the same table layout as the editing is done, but without the fields. I wanted to avoid having to redefine my forms twice and I wanted to reuse some generic templates as much as possible. Obviously this is not good for performance, but I use it for an intranet app with a lot of objects, but not that big a load. Their is definitely still a lot of room for improvement, and maybe all this could have been done much easier. How to use? See the docstring.

Block IP addresses

I needed a quick and dirty way to block a user from my site. Just include this middleware class under the 'MIDDLEWARE_CLASSES' variable in your settings.py file. Also include the variable BLOCKED_IPS = ('123.123.123.123',) variable, where the value is a tuple of IP addresses you want blocked from your site.
