Pydantic does not accept pre-compiled Pattern objects #1237
Description
Bug
Pydantic does not accept pre-compiled regular expression Pattern objects as valid values for Pattern-typed fields. Linked to issue #1211 . I'll create a pull request.
By the way, I've just discovered Pydantic and it blows my mind. Incredible work, thank you!
