hello I ran into an error when working on the sqlalchemy engine, created the database_url with the correct password but it gives me this error -sqlalchemy.exc.OperationalError: (psycopg2.OperationalError) connection to server at -localhost- (::1), port 5432 failed: FATAL: password authentication failed for user -postgres- -I am using the correct password because that's what I use to connect to the DB anytime I log in. thank you, anyone, in advance

for those having the problem in 10:25:39 with the PostOut model, he didn't realize but what he changed at the end was including the BaseModel on the PostOut class instead of the PostBase which is what got you a bunch of errors beacause you're passing to the class the atributes of the PostBase Model and you're passing the same thing to the Post object. I hope it helped

Random question, maybe my brain is fuzzy from too much watching, but in the Docker section, did I miss where the docker postgres image gets tables and schema structure? How do you do that as the main -hello world- works fine, but any other requests fail because there is no table structure.

Hey Guys,
I have run into an error when running heroku run -alembic upgrade head-, -> password authentication failed for user.... I dont understand how this can be happening when i didnt get this error to run the server previously. Has anyone seen this or be able to help me out?

Thank you so much for this awesome course! I'm a junior developer working on my first API (FastAPI) at work, this gives me the necessary foundation. Everything fits together and that the chosen tools and methods are relevant in the industry... This is highly valuable!

I have a small problem, at 43:43 timestamp, we can see that the terminal has colors like INFO is green, then there is Cyan coloured number : 5480 but I can't see the colors, instead i see random code like '?[32m' or '?[36m'. Please help if you find a solution

A List wasn't the best choice to store that type of data, a dictionary would have been more suitable where Mapping was done as so all that was necessary is -dict.get(id)- to see if the key exists, this would also be convenient to solve the dupe id issue

4:26:27 Why do you return a dictionary to tell the front end information rather than simply returning a simple print statement/message? Im not through the whole course yet but i cant seem to understand the logic behind this...
