开发django过程中遇到的问题

ImportError：

1.cannot define “template_pack”

django——crispy_forms问题：注释掉local/lib/python2.7/site-packages/crispy_forms/utils.py中73行“form, form_style, context, template_pack=template_pack,”的“template_pack=template_pack,”即可

2.auth.User.groups: (fields.E304) Reverse accessor for 'User.groups' clashes with reverse accessor for 'NewUser.groups'.
HINT: Add or change a related_name argument to the definition for 'User.groups' or 'NewUser.groups'.

扩展user的情况下，需要在setting中注明:   AUTH_USER_MODEL =  'path.your new user model_name'
