Month / Year dropdown widget

This is an adaption of [django.forms.extras.widgets.SelectDateWidget](http://code.djangoproject.com/browser/django/trunk/django/forms/extras/widgets.py#L16) which has no day dropdown - it still produces a date but with the day set to 1. Example use class myForm(forms.Form): # ... date = forms.DateField( required=False, widget=MonthYearWidget(years=xrange(2004,2010)) )

UserProfileForm

We often need to use a Profile form and we want to be able to modify the first_name, last_name and sometimes the email address. Here is how I do it. In this case I want to check the email so I did a specific form for it. But it is quite easy to add it.

Modeli18n

This is a Model base class used to support internationalization (i18n) for your models. This code extends the Django's Model class so you can use all available options from Model safely. Basicly, it uses introspection to create a sub-model to your model to hold translation. **Features:** 1. Simplicity of use. You simply extend your model with this class and add all the fields that needs to be translated are placed under the `locale` sub-class; 2. The code uses the `django.utils.translation.get_language()` to select the current language; 3. You can use `python ./manage.py syncdb` command safely; 4. Force the user to enter a translation for each language even if the fields can be blank. This makes sure that all objects are returned safely. **Ordering by locale fields:** To sort on translated fields, use the form of "model_i18n__transfieldname" (see code for example). **Limitation:** Do not use localized fields in __unicode__, the admin will throw an exception when you'll add a new item and do "save and continue". Just drop a comment if you need more information. (last update: 06/15/2010)

CollectionFrom (GeometryCollection <-> Geometry Fields!)

Motivation: We can't use GeometryCollections to do filters, etc in GeoDjango due to incomplete underlying libraries. But with this CollectionFrom field we can get all the benefits of working with GeometryCollections but still query based on points, lines, polys. If you're using GeometryCollectionFields and see this error: DatabaseError: Relate Operation called with a LWGEOMCOLLECTION type. This is unsupported. Then this will probably be helpful for you.

HttpMethodsMiddleware

This middleware allows developers to "fake" browser support for HTTP methods. Even though most modern browsers only support GET and POST, the HTTP standard defines others. In the context of REST, PUT and DELETE are used for client interaction with the server. For forms with a PUT or DELETE method, this middleware will change them to go through POST, and will include an invisible field called "method_middleware_transform" that carries the originally intended method. So, `<form method="PUT" ...>...</form>` More or less becomes `<form method="POST" ...><input type=hidden name="method_middleware_transform" value="PUT"></form>` (with a few other minor HTML modifications) The process is completely transparent to the developer... you never have to deal with the fact that browsers don't support the standard methods. **One caveat** is that server interaction via `XMLHttpRequest` (AJAX) requires special attention... this middleware won't properly setup your XMLHttpRequest to take advantage of this functionality. This is a combination of the work of Jesse Lovelace and the Django CSRF middleware.

Updated FileField / ImageField with a delete checkbox

Example model: class MyModel(models.Model): file = RemovableFileField(upload_to='files', \ null=True, blank=True) image = RemovableImageField(upload_to='images', \ null=True, blank=True) A delete checkbox will be automatically rendered when using ModelForm or editing it using form_for_instance. Also, the filename or the image will be displayed below the form field. You can edit the render method of the DeleteCheckboxWidget or add one to RemovableFileFormWidget to customize the rendering. UPDATE: 5. April 2009. Making it work with latest Django (thanks for the comments).
