尝试从python manage.py shell创建对象

1)从列表,数据框或其他内容创建模型的每个实例(在您的情况下为足球俱乐部)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)

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

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

中所述,此方法比逐个创建实例要快得多。
