Bulk create model objects in django

Question

I have a lot of objects to save in database, and so I want to create Model instances with that.

With django, I can create all the models instances, with MyMode

Answer 1

Here is how to bulk-create entities from column-separated file, leaving aside all unquoting and un-escaping routines:

SomeModel(Model):
    @classmethod
    def from_file(model, file_obj, headers, delimiter):
        model.objects.bulk_create([
            model(**dict(zip(headers, line.split(delimiter))))
            for line in file_obj],
            batch_size=None)
