Simple Flatpage Navigation Items

Flatpages are great for simple html content. However, I wanted some way to associate a navigation menu (just a snippet of HTML) with one or more FlatPage objects. Additionally, I wanted to be able to edit these throught the Admin. This was my solution.

Custom nose runner

This method is replacement for django test runner. It uses nose test runner, which will discover all tests in the application (not even in tests module of applications). For installing put in settings.py: `TEST_RUNNER = 'nose_runner.run_tests'` where *nose_runner* is module containing the code

Captcha without Freetype or the Python Imaging Library (PIL)

If, like me, you've had trouble installing the [Python Imaging Library](http://www.pythonware.com/products/pil/) or [FreeType](http://freetype.sourceforge.org), you may have also had trouble getting a captcha to work. Here's my quick and dirty workaround — be warned, this is _very_ low level security, and shouldn't be used on high-profile sites. Originally published at <http://gregbrown.co.nz/code/django-captcha-without-freetype-or-pil/> Credit to the author of [django-simple-captcha](http://code.google.com/p/django-simple-captcha/), from whom I borrowed most of this code. ### Usage from django import forms from ABOVE-FILE import CaptchaField class CaptchaTestForm(forms.Form): myfield = forms.TextField() security_check = CaptchaField()

EditingMiddleware (quickly open views and templates in your text editor!)

Heavily based on [Snippet 1033](http://www.djangosnippets.org/snippets/1033/) and [Snippet 766](http://www.djangosnippets.org/snippets/766/). This snippet tracks what view and templates are used to render HTML responses and inserts a small dialog in the top right corner of the output with links to all the files. If your text editor support opening files from a browser protocol you can click the links to open the files right up! For example TextMate supports the `txmt://` protocol. Really saves some time if you find yourself editing a lot of templates. ![txt](http://img.skitch.com/20090602-11df2tfg273p99i95nfx6a74qe.png) **Usage** 1. Save this snippet in a file called `middleware.py` on your Python Path. 2. Add `middleware.EditingMiddleware` to your `MIDDLEWARE_CLASSES`. 3. Browse to any HTML page on your site!

partial tag

This is another partial tag, taken from a previous partial tag. The previous one assumed template locations by hardcoding in "partials/%s", etc. I took all that out, and made it work. And I took out the not needed third parameter for passing in your own data So now you call like this: {% partial "partials/mypartial.html" %} It passes the template context var into the partial, so anything you do in the main template, will work in the partial Just make sure you've got all the right imports.

split_contents2 for template tags

Is an updated way of splitting contents for a token, it does the split, but fixes the list.. EX: From a tag call like this: {% partial "partials/template.html" %} usually you get: ['partial','"partials/template.html"'] notice the " double quotes fixes it with: ['partial','partials/template.html'] takes out the " quotes

Cleanup dirty HTML from a WYSIWYG editor

My admin allows editing of some html fields using TinyMCE, so I end up with horrible code that contains lots of nested `<p>`, `<div>`, `<span>` tags, and style properties which destroy my layout and consistence. This tag based on lxml tries to kill as much unneeded tags as possible, and style properties. These properties can be customized by adapting the regex to your needs.

StaticField for non-changing text data in forms

This Field, Widget and the three lines of code in the form's clean method allow an easy (and hopefully general) way to add simple, unchangable text to a form. Example use: class OnlyTextForm(forms.ModelForm): points = StaticField(label=_('Points')) reviewer = StaticField(label=_('Reviewer')) def clean(self): for name, field in self.fields.items(): if isinstance(field, StaticField): self.cleaned_data.update({name: self.initial[name]}) return self.cleaned_data

pavement file for deploying django projects

This is the pavement file I use to deploy a django site. It's in early stages. Right now it copies everything up to the desired server over scp. But I think I'll change it to rsync in the future. It requires pavement, and pexpect. The pavement file takes slight instruction from your settings.py file. For server information, and "lib_apps" to copy into the lib directory. An example of a settings file that I use with this pavement file: http://gitweb.codeendeavor.com/?p=django_empty.git;a=blob_plain;f=settings.py;h=23bda7d2a1eb2a52ca0859004ecccd206dade4ec;hb=5d672178dab282caeed5ff0de7ed807c72e44f74 Specifically, check out the bottom for two vars: "LIB_APPS" and "DEPLOYMENTS" A good example of my empty django project is here: http://gitweb.codeendeavor.com/?p=django_empty.git;a=tree;h=5d672178dab282caeed5ff0de7ed807c72e44f74;hb=5d672178dab282caeed5ff0de7ed807c72e44f74 I think the one thing that's missing is a way to re-spawn fcgi processes. Which I'll hopefully get around to adding sometime soon. Also, I need to do a little work at making sure source control files don't get pushed through scp.

Extend simplejson to understand closures, functors, generators and iterators

For most applications, simplejson.dumps() is enough. But I’m especially fond of iterators, generators, functors (objects with a `__call__()` method) and closures, dense components that express one thought well: the structure of a tree, or the rows of a database, to be sent to the browser. The routine dumps() doesn’t understand any of those things, but with a simple addition, you can plug them into your code and be on your way without headache. Dumps() just calls JSONEncoder(), and JSONEncoder has a routine for extending its functionality. The routine is to override a method named default() (why “default?” I have no idea) and add the object types and signatures you want to send to the browser. Normally, this exists for you to provide custom “object to JSON” handlers for your objects, but there’s nothing custom about iterators, generators, functors and closures. They are native Python objects. This snippet provides the functionality needed by JSONEncoder to correctly dereference these useful Python objects and render their contents.
