I guess it's possible, but i still didn't find any solution. I'm looking for a way to use Django URL pattern matcher for another data processing

For example:
I have following pattern
"MySpecific-(?P<my_parameter>)-(?P<my_second_parameter>)"
and following regular string
"MySpecific-test-123"

so what i want is to extract parameters by pattern form regular string in a dict shape

{
  "my_parameter": "test",
  "my_second_parameter: "123"
}



Pseudo code:

import matcher from django_matcher_package

my_pattern = "MySpecific-(?P<my_parameter>)-(?P<my_second_parameter>)"
my_string = "MySpecific-test-123"

extracted_values = matcher.match(my_pattern, my_string)

    Django simply uses regex... – Stargazer Jun 12 at 13:01
  • Yes i know, but there is something else. This pattern seems to be regex non friendly test/url/<int:count> but it works fine – dorintufar Jun 12 at 13:15
  • @dorintufar: yes that's the new way of doing them, that is completely distinct from the regex-based ones. – RemcoGerlich Jun 12 at 13:20

That's just Python's regular expression support:

>>> pattern="MySpecific-(?P<my_parameter>.+)-(?P<my_second_parameter>.+)"
>>> s="MySpecific-test-123"
>>> import re
>>> match = re.match(pattern, s)
>>> match.groupdict()
{'my_parameter': 'test', 'my_second_parameter': '123'}

Note I added '.+' to your pattern twice, otherwise there wouldn't be anything to match in those groups.

  • This way will work 100%, but it will take too long to explain to system operators that after each parameter there should be additional .+ characters xD – dorintufar Jun 12 at 13:17
  • @dorintufar: they aren't extra, you also need them in your Django URLs. The one you had wouldn't match on your string in Django either. – RemcoGerlich Jun 12 at 13:19
  • Yep, i see. Thank you – dorintufar Jun 12 at 13:36
