External Link stackoverflow.com [1] Today I came across some sqlalchemy models that created some relationships, some used backref some used back_populates. I was stumped why, I had never came accross backref before and I felt skill issues sinking in. backref is considered legacy # [2] https://docs.sqlalchemy.org/en/14/orm/backref.html As stated in the sqlalchemy docs, backref is a legacy feature. Its shorthand to creating relationships between parent and child, but only adding it to the parent. While this is simpler it introduces some invisible magic.

2.5 Admins 180: Email 777 – 2.5 Admins 2.5admins.com [1] How do you pronounce URL, is it U.R.L or Earle? I’m about 50/50, mostly when I am in a hurry I use Earle as it is one syllable and easy to say. I picked this up from MPJ of fun fun function, who took over Dev Tips. In this episide Jim uses Earle and they make fun of him. If it’s good enough for Jim, I am done with my 50/50 and I’m going all in on Earle. Episode also included a fastinating corrdinated attack that used Ars Technica profile photos communicate directions for the next attack via query parameters in the image url.

- This really makes me want to try Dolphin Mixtral with ollama now. It looks very impressive from this video. The ability to keep adding features before becoming confused is though with a lot of these llms. Being chat based, this is not a co pilot replacement. I was really hoping for an in line co pilot like tool that I can run locally. I have not used co pilot yet, but I have had great luck with codeium.

- Thor is just straight up a great Human being! Getting a gaming company to tie power and progression with being nice is an incredible feat.

- Great take on low code. I have definitely felt the pressure of being presented low code options, “look it does almost everything you need, and you can do it without code.” Granted there are tons of great low code environments that serve their markets well (things like zapier). As pointed out here when they fall short rather than being hard, it goes to nearly impossible. As Theo points out here many applications follow an 80/20 rule. 80% of the app is really easy to put together, and takes about 20% of the time, probably less. What no code does is it takes that 80% that is already easy, makes it even easier ( pitches it as faster whether or not that is true ), and makes the last 20% of the project impossibly hard to create and maintain, so you just should have picked a tool that had the capability of doing the whole thing from the start anyways.

- I’ve heard prime say just give it the one eyed fighting kirby so many times, and execute it few times, and there is no way to find it online, so this will be the link that I will come to, when I need to remember what @theprimeagen means when he says Give it the one eyed fighting kirby. :s/\(.*\);/console.log(\1) So what is this? # [1] This is a vim substitute comand to replace text in the buffer. the one eyed fighting kirby is a regex capture group to capture everything between matches, and assign it a value to place back in after the match. substitute in a nutshell, :s/<what you want to replace>/<what you want to replace with> More examples # [2] Here is a contrived example of text. here there from here go there here = some_fuction(there) Now for some reason I want to switch all of the words here and there. I can do that with three capture groups, \1 is here, \2 is everything between, \3 is there. :%s/\(here\)\(.*\)\(there\)/\3\2\1 Just give it the one eyed fighting kirby ~Prime still struggling # [3] I thought this explaination from phind was good and more verbose than mine. --- describe this vim substitute regex :%s/(here)(.)(there)/\3\2\1 ANSWER | PHIND V9 M...

Read a Range of Data - LIMIT and OFFSET - SQLModel SQLModel, SQL databases in Python, designed for simplicity, compatibility, and robustness. sqlmodel.tiangolo.com [1] Today I was running some sqlmodel queries through the sqlalchemy orm. Admittedly I’ve not done enough orm queries before, and I’ve done quite a bit of raw sql. I was trying to get objects from two separate models that had relationships setup. session.query(User, Images).where(User.id == 3).all() It is incredibly slow, and gives me the following warning. SELECT statement has a cartesian product between FROM element(s) What I learned from the SQLModel docs is that you should give it a join to correct this and go much faster. session.query(User, Images).join(Images).where(User.id == 3).all() References: [1]: https://sqlmodel.tiangolo.com/tutorial/limit-and-offset/

Template Designer Documentation — Jinja Documentation (3.1.x) jinja.palletsprojects.com [1] html [2] code generated by my jinja templates generally look half garbage because of indents and whitespace all over the place. I just learned about these pesky Whitespace Control characters that can get rid of the whitespace added from templating. You can also strip whitespace in templates by hand. If you add a minus sign (-) to the start or end of a block (e.g. a For tag), a comment, or a variable expression, the whitespaces before or after that block will be removed: {% for item in seq -%} {{ item }} {%- endfor %} References: [1]: https://jinja.palletsprojects.com/en/3.0.x/templates/#whitespace-control [2]: /html/

Intro - Minecraft Server on Docker (Java Edition) Documentation for Minecraft Server on Docker docker-minecraft-server.readthedocs.io [1] I just learned that if you can exec into the container running minecraft with the itzg/minecraft container you can run rcon-cli to get command access to the server. You need to set the RCON_PASSWORD if you want to access rcon remotely, but if you have not already done this and have access to the server you can just run rcon-cli when you are in.

- Theo’s response puts a lot of my feelings about unit testing into words. It’s crazy how cargo culty it becomes that the echo chamber of twitter can bring in beliefs that we think we believe, but have not experienced enough or put enough thought in to form our own opinion.

External Link stackoverflow.com [1] After struggling to get dependencies inside of middleware I learned that you can make global dependencies at the app level. I used this to set the user on every single route of the application without needing Depend on getting the user on each route. from fastapi import Depends, FastAPI, Request def get_db_session(): print("Calling 'get_db_session(...)'") return "Some Value" def get_current_user(session=Depends(get_db_session)): print("Calling 'get_current_user(...)'") return session def recalculate_resources(request: Request, current_user=Depends(get_current_user)): print("calling 'recalculate_resources(...)'") request.state.foo = current_user app = FastAPI(dependencies=[Depends(recalculate_resources)]) @app.get("/") async def root(request: Request): return {"foo_from_dependency": request.state.foo} References: [1]: https://stackoverflow.com/questions/72243379/fastapi-dependency-inside-middleware#answer-72480781

Handling Errors - FastAPI FastAPI framework, high performance, easy to learn, fast to code, ready for production fastapi.tiangolo.com [1] This page shows how to customize your fastapi [2] errors. I found this very useful to setup common templates so that I can return the same 404’s both programatically and by default, so it all looks the same to the end user. from fastapi import FastAPI, Request from fastapi.responses import JSONResponse class UnicornException(Exception): def __init__(self, name: str): self.name = name app = FastAPI() @app.exception_handler(UnicornException) async def unicorn_exception_handler(request: Request, exc: UnicornException): return JSONResponse( status_code=418, content={"message": f"Oops! {exc.name} did something. There goes a rainbow..."}, ) @app.get("/unicorns/{name}") async def read_unicorn(name: str): if name == "yolo": raise UnicornException(name=name) return {"unicorn_name": name} References: [1]: https://fastapi.tiangolo.com/tutorial/handling-errors/ [2]: /fastapi/

logs with FastAPI and Uvicorn · Issue #1508 · fastapi/fastapi Hello, Thanks for FastAPI, easy to use in my Python projects ! However, I have an issue with logs.

GitHub · github.com [1] Setting an additional log handler to the uvicorn logger for access logs in fastapi [2] was not straightforward, but This post was very helpful. @app.on_event("startup") async def startup_event(): logger = logging.getLogger("uvicorn.access") handler = logging.StreamHandler() handler.setFormatter(logging.Formatter("%(asctime)s - %(levelname)s - %(message)s")) logger.addHandler(handler) References: [1]: https://github.com/tiangolo/fastapi/issues/1508 [2]: /fastapi/
