Here is a snippet provided by @tiangolo to store the users jwt inside of a session cookie in fatapi. This was written in feb 12, 2020 and admits that this is not a well documented part of fastapi [2].
It’s already in place. More or less like the rest of the security tools. And it’s compatible with the rest of the parts, integrated with OpenAPI (as possible), but probably most importantly, with dependencies.
It’s just not properly documented yet. 😞
But still, it works 🚀 e.g.
from fastapi import FastAPI, Form, HTTPException, Depends
from fastapi.security import APIKeyCookie
from starlette.responses import Response, HTMLResponse
from starlette import status
from jose import jwt
app = FastAPI()
cookie_sec = APIKeyCookie(name="session")
secret_key = "someactualsecret"
users = {"dmontagu": {"password": "secret1"}, "tiangolo": {"password": "secret2"}}

To persist data in duckdb you need to first make a connection to a duck db database.
con = duckdb.connect('file.db')
Then work off of the connection con rather than duckdb.
con.sql('CREATE TABLE test(i INTEGER)')
con.sql('INSERT INTO test VALUES (42)')
# query the table
con.table('test').show()
# explicitly close the connection
con.close()

duckdb can just query any pandas dataframe that is in memory.
I tried running it against a list of objects and got this error. Great error message that gives me supported types right in the message.
Make sure that "posts" is either a pandas.DataFrame, duckdb.DuckDBPyRelation, pyarrow Table, Dataset, RecordBatchReader, Scanner, or NumPy ndarrays with supported format

When setting up a new machine, vm, docker image you might be installing command line tools from places like pip. They will often put executables in your ~/.local/bin directory, but by default your shell is not looking in that directory for commands.
WARNING: The script dotenv is installed in '/home/falcon/.local/bin' which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.
To solve this you need to add that directory to your $PATH.
export PATH=$PATH:~/.local/bin
To make this change permanant add this line to your shell’s init script, which is likely something like ~/.bashrc or ~/.zshrc.

Filter Data - WHERE - SQLModel
SQLModel, SQL databases in Python, designed for simplicity, compatibility, and robustness.
sqlmodel.tiangolo.com [1]
When fetching pydantic models from the database with sqlmodel, and you cannot select your item by id, you probably need to use a where clause. This is the sqlmodel way of doing it.
Here is a snippet of how I am using sqlmodel select and where to find a post by link in my thoughts database.
@post_router.get("/link/")
async def get_post_by_link(
*,
session: Session = Depends(get_session),
link: str,
) -> PostRead:
"get one post by link"
link = urllib.parse.unquote(link)
print(f'link: {link}')
post = session.exec(select(Post).where(Post.link==link)).first()
if not post:
raise HTTPException(status_code=404, detail=f"Post not found for link: {link}")
return post

urldecoder.io [1]
In order to turn url encoded links back into links that I would find in the database of my thoughts project I need to urldecode them when they hit the api. When anything hits the api it must urlencode the links in order for them to be sent correctly as data and not get parsed as part of the url.
Here is a snippet of how I am using urlib.parse.unquote to un-encode encoded urls so that I can fetch posts from the database.
@post_router.get("/link/")
async def get_post_by_link(
*,
session: Session = Depends(get_session),
link: str,
) -> PostRead:
"get one post by link"
link = urllib.parse.unquote(link)
print(f'link: {link}')
post = session.exec(select(Post).where(Post.link==link)).first()
if not post:
raise HTTPException(status_code=404, detail=f"Post not found for link: {link}")
return post

MDN Web Docs · developer.mozilla.org [1]
In order to send data that includes special characters such as / in a url you need to url encode it. You have probably seen these many times in urls with things like %20 for spaces.
I’m working on a chrome extension to make quick blog posts, like thoughts or a persistent bookmark tool with comments. The backend is written in fastapi [2] and when I check to see if I have a post for a page I need to url encode it.
curl -X 'GET' \

Here is how I used javascript’s encodeURIComponent to turn my chrome extension into a notification when I already have a post for the current page.
