Answer 1

尝试从python manage.py shell创建对象

1）从列表、数据框或任何内容创建模型的每个实例（本例中为足球俱乐部），并将其存储在列表中：

from django_app.models import ClubToChoose
# read the data from .csv or .txt file, etc. instead of this list
clubs = ['Flamengo', 'foo', 'bar']
# this list will contain your data in django format - as a model instance
clubs_model_instances = []

for club in clubs:
    model_instance = ClubToChoose(choice_text=club,
                                  votes=0)
    clubs_model_instances.append(model_instance)

2）使用bulk_create()方法将您的选择添加到数据库：

ClubToChoose.objects.bulk_create(clubs_model_instances)

文件：https://docs.djangoproject.com/en/2.0/ref/models/querysets/#bulk-create

这种方法比逐个创建实例快得多，如https://docs.djangoproject.com/en/2.0/ref/models/querysets/#create中所述
