I still did not understand how you solved redundancy of username usinging "try , except" . Does it look through the database if the username is already taken?

Hey, OMG the "try except" thing worked! I was stuck here for hours trying other methods to check for duplicate username. It always returned an internal server error. Thank you!

Thanks for the video it was really helpful. However, I get the following error after running the code with check50: 🙁 logging in as registered user succeeds excepted status code 200, but got 400. I not know what causes this error since I could log into the registered user while I was testing the code myself. I have written the same code that you have shown in this video after trying to solve this issue on my code. I would be really glad if you could look into this issue. Thanks. (16:32 contains the same error message)

Great explanation. I actually do alittle bit different to what you do in the process of checking for username but your code is much more better. Thanks

Thank you for all your videos, they have been super helpful. I have been working on finance for a month now and I cannot figure it out. I keep getting this error and I am not even sure what part of the code is off 🙁 any suggestions would be greatly appreciated!

🙁 logging in as registered user succceeds

Cause

application raised an exception (see the log for more details)

Log

sending POST request to /login

exception raised in application: RuntimeError: near "transaction": syntax error
