我想在save方法中保存部分URL,例如:
我有来自youtube的链接:
www.youtube.com/watch?v=wMXHHuEGuO8
但我只想保存这部分:wMXHHuEGuO8
我怎么能在Django中做到这一点?

这个答案特定于Python 3,并没有使用任何特定于Django的调用。您可以使用urllib.parse模块将URL解析为其部分:
import urllib.parse
url = 'www.youtube.com/watch?v=wMXHHuEGuO8'
query_string = urllib.parse.urlparse(url).query
print(query_string)
# v=wMXHHuEGuO8
query_dict = urllib.parse.parse_qs(query_string)
print(query_dict)
# {'v': ['wMXHHuEGuO8']}
print(query_dict['v'])
# ['wMXHHuEGuO8']
print(query_dict['v'][0])
# wMXHHuEGuO8

如果它的格式与youtube.com/watch?v=相同,则可以将其拆分为:
your_url = www.youtube.com/watch?v=wMXHHuEGuO8
splited = your_url.split('watch?v=')
# you will have a list of two elements, first one is
# www.youtube.com/ and the other one is wMXHHuEGuO8
