I use this snippet when creating newforms with form_for_model and form_for_instance. Both do not have an argument that lets you filter out fields easily so I wrote this instead. Typical use: `form_class = form_for_instance(obj, fields=ignore_fields(model_class, ['field_name1']))`
Use `{% urchin "UA-1234567-1" %}` to insert the Javascript snippet for a Google Analytics site.
Generator to help make newforms classes a bit like inspectdb does for generating rough model code. This is a standalone script to go in your project directory with settings.py and called from the prompt. It looks up the model, and generates code to copy/paste into your app. Hopefully to make a building a custom form with a lot of fields a little easier. Every argument should be a model identifier of form appname.modelname. Usage from the command line: python form_gen myapp.MyModel myapp.MyOtherModel
This snippet allows you to use @mako("templatename.mako") to define a mako template to use. Your python method just has to return a dictionary that will be passed to mako's context, after the addition of the "request" variable to the dictionary. If you return a non-False non dictionary object, it will return that instead of trying to render the template. The **request** variable is automatically added to the template's context. It also searches the current application's mako_templates/ subdirectory first before searching under the current directories mako_templates/, and does not use other application's mako_templates/ subdirectories at all. On Mako exceptions, it will display the Mako error page when debugging is enabled (hoping for extensible exception handling in the future to keep consistency) I got the idea from a [CherryPy tool](http://tools.cherrypy.org/wiki/Mako).
[The Session documentation](http://www.djangoproject.com/documentation/sessions/) rightly warns of the dangers of putting a session ID into a query string. Sometimes, however, you have to do it - perhaps your client has mandated support for browsers with cookies disabled, or perhaps (as in my case) you're just dealing with a slightly broken client browser. This middleware pulls a session ID out of the query string an inserts it into the cookies collection. You'll need to include it in your MIDDLEWARE_CLASSES tuple in settings.py, *before* the SessionMiddleware. *Please* read my [full blog post](http://www.stereoplex.com/two-voices/cookieless-django-sessions-and-authentication-without-cookies) about for the dangers of doing this, and for full instructions and examples.
Provides the method from_related_ids, which lets you select some objects by providing a list of related ids (The huge difference to __in is that the objects have to match al of the ids, not only one) Model Example:: class Article(models.Model): text = models.TextField() tags = ManyToManyField('Tag') objects = AllInManager() Usage:: Article.objects.from_related_ids((1,2,3,4), 'tags')
You have two models, one of which also has an image field. You want to get the data into a form and edit it. This also requires showing the url of the image, if there is one, on the form. This is a complete working example. No big deal, but for newbies, a complete working example could be valuable.
**Attention! This snippet must be ignored**, like [zgoda](http://www.djangosnippets.org/users/zgoda/) pointed with reason: already exists this functionality in `markup` contrib. **Explanations:** This template filter allows you to render easily a reStructuredText to **HTML** or another format it supports. **Setup:** Insert the snippet into an_app/templatetags/restutils.py. **Use in template:** `{% load restutils %}` and use it as following: - `{{ entry.content|rest:"html" }}`
If you want to test a post request to a form, you need to give all input fields, even if you just want to test if one value gets changed. This snippets parses the HTML of a view and gives you a dictionary that you can give to django.test.Client.

This is a simple template tag to create Tag Clouds. Based on the number of Posts (change the model_name according to your schema), Tags are provided different size ( most number of posts => most popular => and hence the largest. We create a property called cloudsize for each tag, which is an integer between minsize and maxsize.

With this middleware in place (add it to the MIDDLEWARE_CLASSES in your settings) you can pass a request to the model via a pre_save method on the model. I'm not sure if it is an improvement over the [threadlocals method] (http://code.djangoproject.com/wiki/CookBookThreadlocalsAndUser) but it may be an alternative that can be improved upon? class MyModel(models.Model): name = models.CharField(max_length=50) created = models.DateTimeField() created_by = models.ForeignKey(User, null=True, blank=True) def pre_save(self, request): if not self.id: self.created_by = request.user
*Usage:* `list|sublist:"a:b"` Returns `list[a:b]` Accepts `":b"` and `"a:"` shortcuts Note that the double quotes are necessary
Working off b23's [recaptcha support](http://www.djangosnippets.org/snippets/433/), I have hacked a way to add recaptcha support using existing comments. I am sure there is a better way, and ultimately I will suggest a patch to add captcha support as an option, but for now I hope this helps. For a more detailed rundown (as well as a working sample), check out my [blog entry](http://nikolajbaer.us/blog/recaptcha-django-free-comments/).
