So I'm attempting to write a Django reusable app that provides a method for displaying your Twitter feed on your page. I know well that it already exists 20 times. It's an academic exercise. :) Directory structure is pretty simple: myproject |__ __init__.py |__ manage.py |__ settings.py |__ myapp |__ __init__.py |__ adm...
I have some html (in this case created via TinyMCE) that I would like to add to a page. However, for security reason, I don't want to just print everything the user has entered. Does anyone know of a templatetag (a filter, preferably) that will allow only a safe subset of html to be rendered? I realize that markdown and others do this....
I have a template filter that performs a very simple task and works well, but I would like to use a decorator on it. Unfortunately the decorator causes a nasty django error that doesn't make any sense... Code that works: @register.filter(name="has_network") def has_network(profile, network): hasnetworkfunc = getattr(profile, "has_%...
I need to do something like {{ article.product.images.first.image.url }} In my template, but there is no "first" (images is a RelatedManager for which I found very little documentation). Is there another way to do this? I can get the first model with {{ article.product.images.get_query_set|first }} But then I need to dig a few pro...

The problem is that if I call a templatetag into a block and it fills me a variiable with the usual context[varname]=something, then if I need that variable into another block, I have to call the templatetag again. This for me means extra db queries, which is really something I'm trying to avoid. This templatetag is called in a base tem...
Is it possible to load a django template tag/filter to use as a function in one of my template tags? I'm trying to load up some of the django.contrib.humanize filters so I can apply them to the results of some of my custom template tags. I can't seem to import them at all, and I don't want to have to rewrite any of that code. ...
I am applying the 'url' template tag to all links in my current Django project. I have my urls named like so... url(r'^login/$', 'login', name='site_login'), This allows me to access /login at my site's root.

I would like to write a Django template tag to which I can pass a variable. I would like the template tag to behave differently depending on what type of model field the variable was derived from (CharField, BooleanField, IntegerField, etc.) as well as other information used in the field's definition (max_length, etc.) I can pass the v...
I'm using a ModelForm class to generate a bunch of checkboxes for a ManyToManyField but I've run into one problem: while the default behaviour automatically checks the appropriate boxes (when I'm editing an object), I can't figure out how to get that information in my own custom templatetag. Here's what I've got in my model: from mypro...

I tried to implement the solution proposed by T. Stone on my question "how-do-i-pass-a-lot-of-parameters-to-views-in-django" ([link text][1]). I can't manage to get any result. It's difficult to find information about the compile_filter(), but as far as I understand cls(queryset=parser.compile_filter(tokens[2]), template=template) should...
