Django：数据库查询写入

写入新的记录：

from movie.models import Movie
...
m = Movie()
m.XXX = XXX
m.save()

查询记录：

m = Movie.objects.get(name=i.name,site=i.site)
m = Movie.objects.get(name=i.name,site=i.site)

条件查询，QuerySet API reference：

items = Movie.objects.filter()
items = Movie.objects.filter().order_by('name')

查询结果排序：

from django.db.models.functions import Coalesce

items = Question.objects.filter(market="sz").order_by(Coalesce('stock_code', 'answer_date').desc())
