Question: 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?

Answer: 
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

```
This one help for multiple dump data into json file

```
from django.core.management import call_command
import sys

sys.stdout = open('app_one/fixtures/apple.json', 'w')
call_command('dumpdata', 'app_one.apple')

sys.stdout = open('app_two/fixtures/banana.json', 'w')
call_command('dumpdata', 'app_two.banana')

```
