Django中合并同一个model的多个QuerySet

【1】相同model
articles1 = Article.objects.order_by("autoid").filter(autoid__lt = 16).values('autoid','title')

articles2 = Article.objects.filter(autoid = 30).values('autoid','title')

articles = articles1 | articles2 #  Model相同，而且没有用切片，并且字段一样时可以这样用

【2】不同model，用chain

from itertools import chain

articles1 = Article.objects.order_by("autoid").filter(autoid__lt = 16).values('autoid','title')

users = UserID.objects.all()

items = chain(articles1, users)
