Use TAB key complete feature in Linux Bash console
One of the best features of Django CMS is to have a wide set of commands to manage your web application from console.
One of the things that Linux users miss when working with a clean instance of Django is the ability of pressing the TAB key while writing a command to autocomplete them or presing TAB key twice to see all the available options.
In this tutorial we will enable such feature.
Bash completion feature works by having a special script that uses the three builtin commands that are available to manipulate the programmable completion facilities, they are:
For each program, there should be a script that uses them to properly enable the autocompletion feature, in Django this file is located in a special directory in main repository, not included in the delivered project by default, it is located at: https://github.com/django/django/master/extras/django_bash_completion
We first start by downloading this file into
~/local/share/django/extras directory, so in this case
~/local/share/django/extras would create the needed path.
Then downloading it and posting in the above directory wget -O ~/local/share/django/extras/django_bash_completion.sh https://raw.github.com/django/django/master/extras/django_bash_completion.

2. Sourcing the file
Now we need to source the downloaded script, so the autocompletion is loaded into our console.
To make it available in our console we just run source ~/local/share/django/extras/django_bash_completion.sh.
But there is a good chance that there is a virtual environment for each project, so depending in what type of virtual environment you are using you can load it at different places:
If you load your virtual environment manually, e.g.:
~/.virtualenvs/MY-PROJECT/bin/activate, with a simple script in you
project root like
#!/bin/bash source ~/.virtualenvs/MY-PROJECT/bin/activate source ~/local/share/django/extras/django_bash_completion.sh
And then load your virtual environment by executing source activate.sh
2.2. Using virtualenvwrapper
For virtualenvwrapper, add
~/local/share/django/extras/django_bash_completion.sh in the
After doing this simple installation, each type we press the TAB key while executing a command with python manage.py TAB it will load the list of available commands or autocomplete accordingly.
