Thanks man , All my doubts regarding the Basemodels and those 2 astrisks and OAuth2 are cleared here.

Thank you Tim for teaching and sharing. To all, study, take breaks, apply knowledge and understanding, keep learning, before you know it your understanding is increasing and becomes comprehensible overtime.

Is possible to create with Oauth a role and permission model similar to RBAC?

from what I previously understand, first user login with username and password from login form and gets jwt token, second user send that jwt token to protected api routes, middleware extract the token from header and check if it is valid or not and decides to continue or stop the request. But the logic in FastAPI is a bit complicated. why do I need to pass again the username and password to access every protected routes?

Thank you Tim for sharing your knowledge although it's fastt paced i could follow pretty good. It would be nice if you'd explain the code more extensively. For example why did you chose to make the functions get_current_user and get_current_active_user async?

This is quite confusing to be honest. But I appreciate its the nature of the topic, not the fault of the video. Will probably need to watch this again.

im getting an error of "'openssl' is not recognized as an internal or external command, operable program or batch file." while creating Secret Key

It could be that 'openssl' is not installed on your system. If you're using a Windows machine, this post comment from GitHub may be useful: github.com/facebook/flipper/issues/3294#issuecomment-1014466972 Alternatively, you can check out this Stack Exchange post for installation instructions on other Operating Systems: stackoverflow.com/questions/9001316/how-to-install-openssl-for-python

Fast but absolutely excellent

@20_1_async Жыл бұрын

For some this may be usefull, if you return an list and wnat to show it in docs response example, use response_model=list[schema] in api decorator. And with python 3.11 you do not need to use response_model var in api decorator but instead use function type hints as: async def my_func(…) -> list[schema]: FastAPI is the best :]

got stuck on the openssl rannd -hex 32 bit. installed pyopenssl. pip list shows its installed. terminal says there is no such module. tried to add it to path but couldnt find the file for it. If i cant even follow a tutorial , should i just give up on programming? i swear to god nothing ever works when i try and do it

@nicofabregues Жыл бұрын

it´s part of the game my friend. I encourage you to keep going, but know that in order to be a programmer the most difficult task it is not how to code a complex method, but to know how to solve a problem. Cause everything its already made, we programmers only copy code from the web and make it work. Search your error, find an alternate path or ask for help, there is no other way than facing the problem and to keep trying for pointless hours until somehow it works, at first you re not going to understand how it happened, but as life keeps going it´s all going to start being easy and making sense

Don't give up Daniel! The odds are that someone else has also had this same issue. This guide has instructions for troubleshooting "No module named 'OpenSSL' in Python": bobbyhadz.com/blog/python-no-module-named-openssl Also, if you need to find the file path for the command, you can use the 'which' command on a Linux system and the 'where' command on a Windows machine. superuser.com/questions/49104/how-do-i-find-the-location-of-an-executable-in-windows linuxize.com/post/linux-which-command/

This is all great but how come there isn’t a library that does most of this work for you ??

@DanielRodriguez-lu3uu 9 күн бұрын

It's kind of the same stuff you will find on FastAPI documentation. Real value would be to show the real flow with a login page, as that part is not that straight forward.

How to test the same on Postman instead of Swagger?

@saif201048 Жыл бұрын

You need to make a request from postman to your API endpoint and pass the token in auth section or in the headers.

This isn't bare metal since there's an OS on top of the hardware. I assume you want docker, but if you know docker then use it, take the knowledge from this video and use containers, should be easy since you imply you're not a new dev.

@supax5073 Күн бұрын

You stolen this from the fastapi official website. This simple means he does never have the experience for, even my 5 years old brother can read a documentations and do as it says. Matter fact, he is not the only one. Most of KZbinrs like him, always stole documentations, and shamelessly coping and posting from the official web. Rather at least, at least, at minimum least have some respect for your viewers and change the official code to alternative code using same approach. Not only that but you also copied it letter pre letter and line be line. Not all whom who have nice desktop setups, is a backend or frontend dev. Rather simple, some guy trying make a living out of youtube. I get it man do your thing, but at least have some respect for your viewers.
