Snippet List
MultiRangeField and MultiRangeFormField
**Designed to hold a list of pages and page ranges for a book/magazine index.** A custom model field (and accompanying form field) that saves comma-separated pages and page ranges in human-readable string form. Includes some clean-up code, so that you can add a new page or range at the end of an existing entry, and it will put it in numeric order and combine runs into ranges. So this: 4-33, 43, 45, 60-65, 44, 59 becomes the tidy 4-33, 43-45, 59-65 **NOTE:** If you comment out the raising of the `ValidationError` in the form field's validate() method, it will actually clean up any extraneous characters for you (which could be dangerous, but for me is usually what I want), so even this horrible mess: ;4-33, 46a fads i44 ,p45o gets cleaned to 4-33, 44-46 *This is the first custom field I've ever written for Django, so may be a little rough but seems to work fine.

Add a CSS class to every field indicating what kind of field it is
The admin site uses a CSS class for each kind of field so that they can be styled easily. This snippet gives ModelForms a similar feature. See also: [James Bennett's explanation of formfield_callback](http://stackoverflow.com/questions/660929/how-do-you-change-the-default-widget-for-all-django-date-fields-in-a-modelform/661171#661171)

Automatic Folder FileField
Your MEDIA_ROOT directories are a mess? FileField save on "upload_to" directories with old/strange/temporary names decided "on the fly" and never fixed down? SmartFolderFileField is the solution! "upload_to" directory depends only on: app, model and field names. No mess, no ambiguities Obviously, in case you need a real callable for a dynamic directory name: please use it! and leave apart FixedFolderFileField Sample: from django.db import models from utilities_app.models import SmartFolderFileField class SampleModel(models.Model): sample_char_field = models.CharField(max_length=50) sample_file_field = SmartFolderFileField()
- upload_to
- FileField
Using Textarea
A very common field in forms is the `<textarea>`, but `newforms` has no such field. Instead, you must use a dummy field (such as `newforms.CharField`) and use the `newforms.widgets.Textarea()` widget to render a textarea.

- textarea

Pretty Print Template Tag
This defines a new template tag that lets you print your rendered templates (or partial templates) in html that has been prettified by beautiful soup. It is dependent on the beautiful soup library (bs4). Not recommended for production but it is helpful for development and serving readable html. {% load whatever_template_file %}' <body> {% pretty %} <h1>Hello, world.</h1> {% endpretty %} </body>

A simple way to force SSL on all pages. It's very simple at this point - the only issue I can see right now and I will address this later is if someone sends http:// in another portion of your url.

Load initial form fields from GET parameters
It is often convenient to be able to specify form field defaults via GET parameters, such as /contact-us/?reason=Sales (where "reason" is the name of a form field for which we want a default value of "Sales"). This snippet shows how to set a form's initial field values from matching GET parameters while safely ignoring unexpected parameters.
