I am trying to use the call_command
method to call the dumpdata command
. Manually, I use it as follows to save the data to a file.
python manage.py dumpdata appname_one appname_two > /path/to/save/file.json
and it saves the json file. Now, I am in a situation where I need to call this command using the call_command
method.
I am able to print out the json from the command using the following:
from django.core.management import call_command
call_command('dumpdata', 'appname_one', 'appname_two')
Is there a way I can save the given data to a file like we do it from the command line?
had to redirect sys.stdout
to the file in order to achieve the above. Something like.
import sys
from django.core.management import call_command
sysout = sys.stdout
sys.stdout = open('filename.json', 'w')
call_command('dumpdata', 'appname_one', 'appname_two')
sys.stdout = sysout
