Capture the Output of a Django Command

The documentation is very slim when it talks about how to call a Django command from code. In order to do this, just use call_command. To solve the trick of capturing the output of this I had to dig a little into the Django source.

The solution to capturing the output of the command being called is passing to call_command an argument called stdout to which you assign where the output is written (a file or any bite stream). Here is an example:

In the above example we call python manage.py dumpdata, which will output all the data from all the models in all the installed apps from the current project in form of a JSON.

Hope it helps 😉
