Template context debugger with (I)Pdb

This allows you to set up a breakpoint anywhere in your template code, by simply writing {% pdb_debug %}. You can then access your context variables using context.get(..) at the pdb prompt. Optionally, install the ipdb package for colors, completion, and more (easy_install ipdb).

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!

Sometimes Tag

Adds a templatetag that works like an if block, but . The one and only argument is a float that reflects the percentage chance. It defaults to .2, %20. {% sometimes %} <img src='spy_behind_sniper.jpg'/> {% else %} <img src='sniper.jpg'/> {% endsometimes %} -- or -- {% sometimes .001 %} You win! {% else %} Sorry, not a winner. Play again! {% endsometimes %} -- or -- {% sometimes .5 %} This shows up half the time. {% endsometimes %}

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

Updated table tag

This table tag helps with render tables, which can be fairly complex. I updated the previous table tag (296). I added support for oddrow,evenrow,lastcellinrow,oddcol,evencol. And made a few minor adjustments to syntax formatting, and some non needed if conditionals These are all of the supported variables available in the context {{table.counter0}} {{table.counter}} {{table.rowcounter0}} {{table.rowcounter}} {{table.startrow}} {{table.endrow}} {{table.oddrow}} {{table.evenrow}} {{table.firstrow}} {{table.lastrow}} {{table.firstcell}} {{table.lastcell}} {{table.lastcellinrow}} {{table.evencol}} {{table.oddcol}} {{table.parenttable}}
