我正在尝试使用key as name和value 创建一个dict 作为相应的User对象.
我从Django shell包装器使用Python shell python manage.py shell:
>>> from django.contrib.auth.models import User
>>> names = ['carl', 'jim', 'jack', 'john', 'mark']
# Now using some dict comprehension
>>> u = {name: User.objects.get(username=name) for name in names}
NameError: global name 'User' is not defined
但是,这对我有用:
u = {}
for name in names:
u[name] = User.objects.get(username=name)
我得到了所需的输出,即:
{
'carl': <User: carl>,
'jack': <User: jack>,
'jim' : <User: jim>,
'john': <User: john>,
'mark': <User: mark>
} …
