36060	"IntegrityError: null value in column ""_order"" when bulk_create()"	Nikolay Fedorov	myoungjinGo	"I have model with {{{order_with_respect_to}}} Meta's option targeted to ForeignKey. If I try to run {{{bulk_create()}}} I catch next error:
{{{django.db.utils.IntegrityError: null value in column ""_order"" of relation ""appname_modelname"" violates not-null constraint}}}
To fix this, I directly set the {{{_order}}} value for each instance in the list to {{{bulk_create()}}}. This is not convenient and adds additional code.
