Disable whitespace trimming in password related serializers

[parth-verma]

Disabled password whitespace trimming as that interferes when password ends with a space, which although should be allowed results in a mutated password. Same way, if a user enters 8 black spaces, the password is rejected stating that it is blank.

Thanks for submitting this PR!

I'm in favor of merging this in. That said, would it make sense to have this as a configurable toggle (with a default to True)?

It would make less sense to add a configurable toggle (since this issue is a bug and not a feature) as mutating the password entered by the user at any point in the lifecycle of the code will have ill effects.

Hey, any update on this?

Hi, as a user of rest-auth, thanks for the contribution! This repo is not maintained anymore, so the development moved to dj-rest-auth. (reference: https://github.com/Tivix/django-rest-auth/issues/568) It may be best, if you move this PR there. (and upgrade to using dj_rest_auth)

new repo link: https://github.com/jazzband/dj-rest-auth (I'm not the upkeeper of that repo, it just makes sense for me to help you merge your PR)

Many Thanks, Barney
