Category: Django,Pythonvbmendes @ 23:25

I released today the version 0.3 of django-meio-easytags. Now it supports template tags that accepts positional arguments (*args) and keyword arguments (**kwargs). If you don’t know how to use this, take a look at Python FAQ. In this release I included some documentation and created a page for the project.

Any doubts, suggestions, feature requests, feel free to mail me, open an issue at Github or leave a comment.

django-meio-easytags released!

Category: Django,Pythonvbmendes @ 01:41

I just released a project I have been working today. A long time ago, I was tired of parsing my template tags by hand, then I created a BaseNode to do this work for me and all I had to do was subclass it and define the method to render the context.

Last friday, my friend Diego Fleury asked me for some help developing a template tag and I talked to him about my old BaseNode. When I showed the code to him, he didn’t understand it so did I. So I wanted to make it cleaner and developed the project django-meio-easytags. It’s hosted at Github (

It’s very easy to create your own template tags with it. Take a look:

Any comments and contributions are welcome.

Domain redirect keeping the URL path with .htaccess

Category: HTTPvbmendes @ 17:07

I had a site hosted at a domain and the client asked me to change the domain. But it’s a very bad idea to simply change a site’s address without thinking about all the users who have bookmarked the old site. It means losing all of them. So I thought that i could do a redirect from the old domain to the new one. This redirect should be using HTTP status code 301 to identify that the site has moved permanently. There are many ways to do such a thing. But one took my attention. Why not use Apache .htaccess file associated with mod_rewrite? Most of the hosting services supports this. Firstly I tried this:

1.RewriteEngine On
2.RewriteBase /
3.Redirect 301 /

This way, all requests to the root of my old domain get redirected to the root of my new domain. But what if I try yo access some path inside my old domain? It would raise a 404 error because it does not have the content anymore. I want that if the user access it redirects him to So I ended up with this:

1.RewriteEngine On
2.RewriteBase /
3.RedirectMatch 301 (.*)$$1

get_first_object_or_none shortcut for Django

Category: Django,Pythonvbmendes @ 10:48

I will talk about a shortcut I developed for the Django framework and always use in my apps. This code is aimed in making a quik shortcut to obtain the first object of a queryset if it exists or None otherwise.

It’s very useful when you want to display the last news in the first page of your website, but don’t want it to break if there isn’t one to show. It’s just a use case for such a code, but there are many more.

In the past I used to write something like this:

2.    first_user = User.objects.all()[:1][0]
3.except IndexError:
4.    first_user = None

This is four lines to do a very simple task and I wanted to evolve this to use only one line of code. So I developed a function that do this to me. It’s inspired in the django.shortcuts.get_object_or_404. Let’s take a look at the code:

1.def get_first_object_or_none(queryset):
2.    try:
3.        return queryset[:1][0]
4.    except IndexError:
5.        return None

I’ve put this code in a module called shortcuts inside my project and now everytime I want to use it I can write this code:

1.from shortcuts import get_first_object_or_none
2.first_user = get_first_object_or_none(User.objects.all())

I think it’s a very good result and helps a lot in my coding. It also made my code more legible and easy to understand. It increased my productivity and I am publishing to increase others productivity also. Any doubts, questions os suggestions, please leave a comment.

Meio.Autocomplete, Mootools Autocomplete plugin

Category: Ajax,Javascript,Mootoolsfabiomcosta @ 23:15

Meio.Autocomplete Docs and Demos

Yeah, we haven’t posted for a while, but it’s time to show you some great code I’ve been working on these days.

I’ve been searching for a good auto-complete plugin for a while. Found some good ones but none of them is perfect and I sometimes had to change their codes to get what I wanted on my projects. So I got tired and decided that I should do my own. My “perfect” one.

Basically I wanted an auto-complete plugin that would act as a select DOM element, which means, when I select a value on the auto-complete list the id of this option is setted somewhere (a hidden field for example) and I needed to have access to the “select” and “deselect” events, that would be fired when I select and deselect an option, respectively.

Meio.Autocomplete does all these simple tasks and more. It’s full of options and I made it in a way that it would be easy to set it up. I really recommend you to take a look at its documentation and see the demos to understand how it works. You can change the demos code too if you wish and run the resulting code, thanks to Mooshell.

I’m open to new ideas, bug fixes, new options etc… Feel free to comment and ask anything (help included) on the documentations page.
