rails devise jwt auth tutorial for rails api only mode

Do you have a guide on password reset with devise jwt?

[@cherukukishore3568]

When i give wrong credentials it's sending plain text like "Invalid email or password". How we can get the JSON formatted message? because react throwing error. How can we handle this? Can you please help me on this?

[@user-sy2zn3zc9t]

Im having an issue where anytime I try and login with postman it just succeeds every time. Even if the email and password are wrong. You got an error saying email and password are invalid

[@dakotamartinez9152]

hey there! Have you tried comparing your code to the finished repository linked in the video description?

[@ken7562]

I also had the same issue even when I cloned the template and tested. Then I realized i was doing a GET request to /login instead of a POST request. Not sure why but a GET request to /login with the same body returns a successful login every time with any credentials (invalid or not).

[@HaliljonJuraboev]

It was great video. However, in the end when I try to check with postman, it is keeping on returning {"status":{"code":422,"message":"User couldn't be created successfully. Email can't be blank and Password can't be blank"}}. I even cloned your repo it is still returning the same error. Do you have any solution for this? Is it may be my PC setting or the gems are no longer functioning as they were?

[@kefahngwei8101]

Setup params in the registration controller. That's how I solved my issue. also define the create method.

[@user-lg2vk6zv7v]

Great video. I am able to signup a new user. However on attempting login via Postman, I get a 401 error with the message "Signature verification failed". Is there a known fix?

[@dakotamartinez9152]

Do you have a repo anywhere I could take a look at? I think this is your Stackoverflow post: stackoverflow.com/questions/77293693/rails-7-api-ony-devise-jwt-signature-verification-failed-on-login. Feel free to add some more information there if you'd like to troubleshoot.

[@dakotamartinez9152]

one thing that occurs to me is that if you did use the GitHub template, you'll need to make sure to generate new credentials so the secret key base exists when the config/initializers/devise.rb attempts to use it to configure signature verification. Not sure if that's the issue, but feel free to keep me posted 🙏

[@user-lg2vk6zv7v]

@@dakotamartinez9152 I think this is actually working. I was just used to seeing the token in the response. It is returned here in the response header. So I will just figure out how to access it. Thanks!

[@Teagou]

I tried this and like others articles of how do JWT with rails, my current_user keeps empty everytime, and always responds unauthorized, i don't know what is wrong 😭😭

[@dakotamartinez9152]

feel free to share your repo if you'd like me to take a look 🙏 I know this stuff can be a headache, happy to help if I can!

[@jmarenas8035]

Hi! great tutorial. this was a huge help on guiding me to build api only app but I noticed i cannot do password confirmation. I added password_confirmation on the database, allowed it to be accepted and added validates_confirmation_of :password, message: "Passwords does not match." but it wont validate. how do I do this?

[@dakotamartinez9152]

Awesome! Glad it was helpful :) Can you clarify what you mean by "it won't validate"? Do you mean that it allows creating of the record even if passwords don't match? The password_confirmation isn't a column in your database, it's a validation feature that's built into devise when you include the :validatable module. You don't need to do anything to enable this validation. I just tested out my GitHub template and sent a request via postman where the password and password_confirmation fields don't match. I get this back: { "status": { "code": 422, "message": "User couldn't be created successfully. Password confirmation doesn't match Password" } }
