Importing file from shell

I didn’t find anything on that nor in the documentation neither in the source, so I’m currently trying with this code:

from import_export.admin import ImportMixin
from yourapp.models import SomeModelResource

filename='/home/user/filename.csv'
format_number = 0  # CSV
resource = SomeModelResource()

mixin = ImportMixin()
input_format = mixin.get_import_formats()[format_number]()
tmp_storage = mixin.get_tmp_storage_class()(name=filename)
dataset = input_format.create_dataset(tmp_storage.read(input_format.get_read_mode()))

resource.import_data(dataset, dry_run=False, raise_errors=True, file_name=filename)

tmp_storage.remove()

Is there a preferred way to do this? Did I miss it somewhere? Because I’m losing all my RAM + 1G of swap to the confirmation page on a big import. And I don’t think that splitting the file and feeding chunks one by one is an adequate workaround.

A PR with tests would be good

A management command would be great.
