Snippet List
Captcha Middleware
A middleware we are using to stop "spam" on Curse. It makes the user fill in a captcha box whenever they submit a form unless a cookie is set (which expires by default after 6 hours) See also [the template](http://www.djangosnippets.org/snippets/128/) Note: render_template is simply a shortcut function we have for doing render_to_response with a request context

Export models as json
I use this script to export a group of models that I want to import later as initial data. It exports them as serialized json, which is perfect for importing later with the loaddata function in manage.py.

IfValueTag
Don't repeat yourself: when you wish to have a block of html with a variable value, but only if the variable is set, you can do this: {% ifvalue company.contact.email as email %} <h3>Email address</h3> <a href='mailto:{{ email }}'>{{ email }}</a> {% endifvalue %} Instead of this: {% if company.contact.email %} <h3>Email address</h3> <a href='mailto:{{ company.contact.email }}'>{{ company.contact.email }}</a> {% endifvalue %} The tags ifvalue and ifnotvalue are provided by this snippet. If you don't specify `as somename`, then the variable's value will be assigned to the name "value".

BritishDateField
The date field in the newforms module includes American style mm/dd/yyyy , which anyone outside the US will recognise as being complete madness. This date field behaves sensibly.

TemplatedForm
Newforms are made to make any kind of customizations easy. Sometimes standard methods of rendering HTML/XML/other content of the django.newforms is not enough to completely satisfy all web design needs so you may want to present forms in own templates. Using templates to render output as HTML or XML is straighforward, and in many cases easier then using standard approach. Step by step usage guide: 1. Create file in your project yourproject/utils/newforms.py and place Class TemplatedForm there 2. Create newforms subdirectory in templates dir, and post 2 templates there (form.html, field.html) from the documentation code for TemplatedForm class 3. Inherit from TemplatedForm in your form class to use this form.

An XML-RPC Decorator
Drop this package wherever you want, import the decorator, and use it with one argument to decorate any function you want (`@xmlrpc('pingback.ping')`). That function is now available on your XML-RPC interface, available through this view. Make sure to provide the view (`call_xmlrpc`) with a URL so that it's accessible.

Markdown and Syntax Highlighting in Django
This is a [Django template tag](http://www.djangoproject.com/documentation/templates_python/#extending-the-template-system "Extending the template system") that renders an arbitrary block of text with Markdown and [Pygments](http://pygments.org "Syntax highlighter"). Use Markdown as usual, and when you have a code block to insert, put it inside `code` tags, with the language as the class: `<code class='python'>print "Hello, World"</code>` To use it in a template, first `{% load ... %}` the tag library, then `{{ content|render }}` your content. The tag takes one optional argument, to enable safe rendering in markdown. To use it, call `{{ content|render:"safe" }}`.

Django Using Stored Procedure
Here is an clean example of using stored procedure using django. It sounds pretty weird "stored procedures in django" but for legacy database system we still need a clean approach to implement stored procedures using django. In this example, I've implemented logic inside models.py by creating a dummy class, i.e a django table (which is comparable to package in your database) and inside this package/class i added stored procedure wrappers. I tested it with boulder-oracle-sprint branch, there is minor issues with LazyDate in db/backend/oracle/base.py but it still working after minor edits in base.py. It worked absolutely fine with MySQL and MSSQL. View is pretty straight forward. Dont forget to create form.html as template and in body just put {{ form }}

simple text image view
**Credit goes to** [Andrew Gwozdziewycz](http://www.23excuses.com/2006/Jun/30/simple-django-view-for-dynamic-text-replacement/) and [Jacob Kaplan-Moss](http://www.jacobian.org/writing/2006/jun/30/improved-text-image-view/) This is basically their code. Only differences: * orientation can be customized * size can be customized * GIF-Image with transparency is created Note: Because of the minimum palette that's used, the font isn't antialiased/smoothened. My url for this view looks like so: (r'^img/(?P<fontalias>\w+)/(?P<orientation>(normal|left|right))/$', 'view.text_to_image')

Days Since Filter
Very simple filter that returns one of the following by default: 1. \# days ago 2. yesterday 3. today 4. January 01, 2007 Example template code: This thread was started {{ post.date_created|dayssince }}. This thread was started today. E-mail sent: {{ email.date_sent|dayssince|capfirst }} E-mail sent: Yesterday Object created: {{ obj.date_created|dayssince|upper }} Object created: 12 DAYS AGO User's bogus birthday: {{ user.get_profile.bday|dayssince }} User's bogus birthday: April 20, 3030

Newforms customs validators
How to proceed to add a custom validator to a newforms field : you just need to create a new class derivated from forms.YourField with a custom clean method. Do not forget the line super(UserField, self).clean(value) ; in our case, it verifies the field attributes : min_length, max_length or required.

Modelaware json serializer
A serializer that handles dicts with querysets and model instances, nice to use if you have a paginator context. paginate_by = 8 paginator = ObjectPaginator(queryset, paginate_by) page = request.GET.get('page', 1) try: page = int(page) object_list = paginator.get_page(page - 1) except (InvalidPage, ValueError): if page == 1 and allow_empty: object_list = [] else: raise Http404 result = { 'object_list' : object_list, 'is_paginated': paginator.pages > 1, 'results_per_page': paginate_by, 'has_next': paginator.has_next_page(page - 1), 'has_previous': paginator.has_previous_page(page - 1), 'page': page, 'next': page + 1, 'previous': page - 1, 'pages': paginator.pages, 'hits' : paginator.hits, } serialize(result, ensure_ascii=False)
