Thanks for ur clear demo. Pls elaborate on the purposes of the try-except codes, when they are to apply. Thanks
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?
SUBSCRRIBED!!! Great work , but After i follow what you said show me in register button intenal issue again i dont know why
pls help
Can someone help with with this error:
exception raised in application: TemplateSyntaxError: unexpected char '&' at 614
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!
you didnt check the database for the addition of a user.
It's not working out when ever I am reloding that register page it's shows error in application and it happened twice to me
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)
Very clear and easy to follow, thanks!
despite the video being so detailed, i love how you keep your codes simple.
Thankyou so much for your vedios
Hello thank you for your explanation but still i have some problems about understanding code.Could you share your code with us please? If you couldn't you can send code to my email. Dont worry i have already finished my CS50 course im not gonna share your code.Thanks 🙂
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
