Running an import command with a list of importers
Exporting a streaming CSV response export
Example import:
from django_csv_utils import CSVImportException, ImportCommand, Importer
from users.models import User
class UserImporter(Importer):
"""Imports User objects from a CSV."""
header = [
"first_name",
"last_name",
"email",
]
def import_row(self, row):
errors = []
first_name = row.get("first_name", "")
last_name = row.get("last_name", "")
email = self.get_str_errblank(row, "email", errors).lower()
if User.objects.filter(email=email).exists():
errors.append("The email {} is already in use".format(email))
if errors:
raise CSVImportException(', '.join([str(e) for e in errors]))
new_user = User.objects.create(
email=email, first_name=first_name, last_name=last_name)
return "Imported {0}".format(new_user.get_full_name())
class Command(ImportCommand):
imports = {'users': UserImporter}Example StreamingHTTPResponse:
from django_csv_utils import StreamingCSVView
from users.models import User
class UserCSVView(StreamingCSVView):
"""Give the list of users."""
header = [
'fist_name',
'last_name',
'email',
]
def get_queryset(self):
"""Return the right list of users."""
return User.objects.filter(is_active=True, is_superuser=False)
def get_row(self, item):
return (
item.first_name,
item.last_name,
item.email,
)1 maintainer
