userbase | Create secure and private web apps | Frontend Framework library

I'm a beginner in FastApi and I'm trying the FastApi tutorial for SQL with OAuth authentication. So far I've managed to create crud for users with password hashing. However now I'm trying the JWT token generation function when user trying to log in but I'm getting confused how to replace actual PostgresSQL database instead the given fake_database example in tutorial. I tried replacing fake_database with db: Session but now I get this error.

sqlalchemy.orm.exc.UnmappedInstanceError: Class 'builtins.str' is not mapped

I want to be redirected to the dashboard page in the website but I'm being redirected to a different url which is not specified in django url and as a result I'm getting page not found error. I don't know why django is not redirecting me to the login_url_redirect that is specified in the settings.py.

I have a little knowledge of Python and was trying to build a simple backend using FastAPI it is a GET REQUEST that returns a user from a PhpMyAdmin MySQL Database. Running the endpoint on Postman returns ERROR 422. What is exactly causing this issue? and what are the possible fixes?

this is my code so far:

here's the

I'm working on a React website and learning about React Hooks. In the project below, header.tsx and home.tsx are both components inside App.tsx. I have a user state object; i.e. const [user, setUser] = useState(); that I load in all 3 files (is this wrong?).

When I log into userbase in home.tsx, the UI reflects the change - the conditional body in home.tsx reflects the fact that user went from undefined to defined and the log out button is shown.

Here's the problem: I want header.tsx to also reflect the change in user; i.e. I expect header.tsx to be "listening" for changes in user and reflecting them on the UI, but it doesn't happen.

Can anyone shed any light? I'm also unsure of the placement of the userbase.init() call.

For some background, this project is based off this tutorial. I modified it to add React Router.

App.tsx

I can use below code to control the authority of menu 15,the role_id's is_edit is 1, the use can change the data in that menu, or user doesn't have access to change/edit data,but the code is ugly, and I only can control one menu.

I want write project using database library (SQLAlchemy). When I use SQLite, all works good, but when I deploy project on server (Heroku with Postgres plugin), It doesn't work. This is code for my database:

I got an error when trying to fetch gRPC API (using C#) to blazor client, at first it worked fine but after adding IdentityServer4 and use CORS for gRPC-Web similar like in the docs. Here's the code relevant to the error.

I need a bit of expert advice. I'm using the firebase cloud function to automate few things ( using this brilliant nodejs package "https://github.com/jdgamble555/adv-firestore-functions".

What happens is, it runs on - onWrite trigger, as I understand when onWrite triggers, it executes the function on each new document or childnode within a document being updated or created or deleted. That package has taken care many of things, but my concern is, executing the functions multiple times does any harm? I'm already making sure than if not required do not hit firestore by using condition checks. So (all) the function executes as I can see it in the log not writing/updating firestore db if not required.

I'm worried if all functions execute all the time will I finish my limits quickly. ( right now I'm testing on Firebase emulator), specially when userbase with increase.

Anything can be done to reduce these calls or its normal?

This program is meant to store a list of usernames, add usernames, and delete them as well. My code works as intended except for the first step. Whenever i enter a name to be stored nothing shows up on the list, and because of this nothing can be deleted. Im not sure where i messed up because i went over it and everything looks fine. I also do not get any error messages so i dont have any direction as to what i should be looking for. Any help would be great, thanks.
