Django Tagging Autocomplete Tag-It

9th February 2012 in Coding

I wanted to implement this functionality in my django projects for some time now and I finally had the chance to work on a project that has this requirement in the specification.

This is an attempt to a django reusable app that aims to be functional but flexible. It's based on django-tagging-autocomplete and depends on django-tagging.

Features:

  • Tag editing
  • Autocompletition
  • Customizable maximum tags number
  • Costomizable max length of each tag
  • Customizable minimum amount of letters before the autocompletition starts
  • Aims to be flexible (help me if you want)

27th October 2010 in Coding

If you are using Django 1.2 and you tried installing Django Tagging Autocomplete you will have noticed that the autocompletition won't work unless you oad a second copy of jQuery. Since I find that a very crappy solution I found a solution that works better for me and I want to share it with you.

How to get comments working with Django StaticGenerator

25th October 2010 in Coding

If like me you are using Django StaticGenerator to speed up your blog you should have noticed that your comments won't work anymore, since StaticGenerator will cache also the fields used by the django comment app to block spam and CSRF attacks.

In this post I'll share with you a quick and easy solution with jQuery.

Django: How to Retrieve Query String Parameters

3rd October 2010 in Coding

If you use Django you will surely know that its url routing is quite strict regarding the prettiness of its URLS but there are still cases in we need to handle query string parameters, like when dealing with external services that return a URL like: callback?verification_code=088145235648fs689sa56h&userid=854 . What to do in this case?

Django: Private File Upload and Serving

30th September 2010 in Coding

The standard Django FileFields assume you want to upload a file in a subdirectory of MEDIA_ROOT, what if you want to upload the file in a private directory above the web root, not accessible via http?
How can you serve the files then?

Django: FileField with ContentType and File Size Validation

24th September 2010 in Coding

Immagine that you need to add the possibility to upload a PDF or Zip file in the django admin, but you want to be sure your client will upload only these two filetypes and not other ones.
You might also need the same functionality in the frontend, so why not use "ModelForm" and have just one validation for both applications (admin and frontend)?

In this short post I'll share with you my simple solution.

IE8 doesn't like 1x1px semi-transparent backgrounds

8th May 2010 in Coding

While developing this web-site I encountered one of those little tipical annoying bugs that characterize Internet Explorer. Even if version 8 is a much better browser than versions 6 and 7, it still sucks under many points of view if compared to other modern browsers like Firefox, Safari, Chrome and Opera.

The issue I want to talk about in this post is the use of a repeated 1x1 pixel semi-transparent background. While this works just fine in all the other modern browsers, IE8 has a little issue that drove me mad.

How to setup StaticGenerator with Apache + mod_wsgi

3rd May 2010 in Coding

I noticed StaticGenerator while I was looking for some cache invalidation solution and I understood that would have been just perfect for my web-site, but the instructions on its web-site show only how to make it work with Nginx configured as frontend server. What if you want to stick on Apache? Read the rest to know...
