python - How to make db dumpfile in django

Question

I want to make a dump in django irrespective of database I am using and can be loaded later. The command 'dumpdata' is perfect for this, but it is printing output on console. More over I am calling it using call_command function so I cannot store its content in any variable as it is printing output on console.

Please let me know how store dump to a file using dumpdata or any other command or api.

Thanks

You just use it like that:

./manage.py dumpdata > data_dump.json

After that action, there will be data_dump.json file in the directory in which you executed that command.

There are multiple options coming with that, but you probably already know it. The thing you need to know is how to redirect output from standard output into some file: you perform that action by putting > before file name.

To append something to the file you would use >>, but since you are dumping the data from Django and the output is most likely JSON, you will not want that (because it will make JSON invalid).
