I am trying to send mail using flask but i keep getting this error

Overriding JSON encoder in Flask 3.0, jsonencoder deprecated?

According to the Flask 3.0 release notes:

> jsonencoder and jsondecoder attributes on app and blueprint, and the corresponding json.JSONEncoder and JSONDecoder classes, are removed.


I need to serialize an ObjectID into str within my app, which i used to do via:

class JSONEncoder(json.JSONEncoder):
def default(self, o):
# objectID
if isinstance(o, ObjectId):
return str(o)
# datetime
if isinstance(o, datetime.datetime):
return str(o)

return json.JSONEncoder.default(self, o)

and

app.jsonencoder = JSONEncoder

how are people doing it now?

Chunks or save()?

I'm a little confused. When saving an uploaded file should I save it using FileSystemStorage( fs.save() ) or should I use chunks? I just want to ensure that I use chunking to save files that are large so that they don't impact performance. But I'm also reading here that files over 2.5MB are streamed to memory by default so does that make chunking obsolete?

Need suggestions to start earning with python

I have been a technology fanatic from a long time. I have a lot of technical skills under my belt. But the sad part is I never knew how to monetize my skills. I have tried using freelancing platforms like fiverr and Upwork. But couldn't find a client. I think I am missing something but I don't know what it is.
I can code confidently and also solve problems. Be it with web technologies or data related. Can you give me suggestions on what I should do?

stripping variable rule in URL after request

hi, I've got a route called /shops/<shopId>/thumbnail, which obviously returns a image/png thumbnail of a certain shop. atop of that there is an after request handler, which adds some caching to the response. is there a way to strip the shopId from the route URL in the after request handler? (so it becomes /shops/<shopId>/thumbnail, instead of e.g. /shops/114/thumbnail)

Need ideas Licencing/api key management

Basically I have developed an DL model,
I will be hosting it in client environment

I want to keep a track that client uses it on only 10k images(hypothetical number), if client process more than 10k than they have to pay extra charge ..


So I need to build an web api app..
Whenever my model gets executed it will connect to my web app server, will check allowed quota and if allowed will process 100 images(because we cannot keep waiting for request every image inference will go very slow), after 100 images it will again check for allowed quota..

Requirements..
1) keep track of usage
2) manually updatable quota and client management
3) api key management, I should be able to provide api keys to client


Is there any open source library which can help?
Will be hosting on GCP but didn't find any service on gcp

RMount allows you to create a file-system like connection to a cloud storage i.e. S3 or SSH server

RMount is a lot more robust than existing libraries and methods to create a remote connection to a cloud server. For example you would want to use Python to connect to a cloud storage such as S3 or a remote server via SSH and treat it like a local file-system.

Note

It has been a pain to write this library given how many things can go wrong when treating a cloud storage as a local file-system. For example, connection drops, or writing of large files can make the system unresponsive and lead to loss of data. The library is supposed to take care of such cases but it is always subject to unforeseen failures.

Feel free to try it out

or pip install rmount

Flask App Stopped Routing! Help!

So this was working not more than an hour ago and now every time I try to route to anything in my routes.py file I am getting a Not Found (404) error. However, a manual route in my __init__.py file works just fine. I've done everything I can think of to correct and undid any changes in the last hour but nothing seems to be working. Please help, I'm about to scrap all of this and just build again, which I really really don't want to do.

Why use the ORM over standard SQL?

I am learning Django and have an intermediate understanding of SQL. I had previously set up scripts with a cursor in Python to just run SQL queries. I'm wondering why Django has you use the ORM to run SQL statements as opposed to just letting you write them in as is?

For example when creating columns:

name = models.CharField(max_length = 50)

instead of the simpler:name VARCHAR(50)

I am fine learning the ORM, but it seems pointless if I already know SQL. Considering that some of my scripts and views in SQL are 100+ lines long, I am anticipating that this is going to be a needless complication trying to rewrite this in the ORM.

So what is the rationale for using the ORM and why does it make you use it if it's literally just going to convert it to SQL before passing it to the SQL server?

Python module that would operate computer like self operating computer using computer vision

So we have multiple modules like selenium etc that automate the computer / web page interaction. Now, self operating computer script that was just released tries to explain to gpt4 what it is looking at on computer screen with gpt 4 vision and allows it to use the computer according to a prompt.

It seems to me that there should be a module that does the same. Explains to llm what it can do with prompts using mouse / keyboard. Customized to different os's.

So then all we would have to do is load the module and be able to do something similar for our own special needs.

Is anyone working on something like this?

Great examples of multi-language flask apps? looking for inspiration

Greetings! I'm thinking to add multi-language support to https://github.com/dgtlmoon/changedetection.io

What's the typical "best practice" workflow here? Something supporting gettext/.po files, which can be edited in another app, and use those strings in the app itself?

(My dream/idea is to have the language flag available in the app, just like any ordinary website)

Whats some flask based webapps that do this really well, that I could check out for inspiration?


Thanks for your time all!

SSHaMan: A TUI for Managing SSH connections using Python & Textual

Good evening everyone. I just wrapped up my first open source project. It's functional at the moment, but definitely still alpha. It's a tool that you can use to manage SSH connections from inside the terminal.

I'm a pretty avid self-hoster with... a lot... of self-hosted services and keeping track of all my VMs is kind of painful with a .bashrc file. So I thought I'd feed two birds with one scone here and make an application to help that and also learn the Textual framework. This application presently doesn't do much that their demos don't do (I was able to repurpose their FileTree and just extend a few buttons), but I plan on digging in and learning Textual in subsequent versions to make this even more useful.

I would welcome any feedback! If anyone would like to contribute, I am absolutely open to PRs as well!

EDIT: D'oh! Forgot the link!

map-nl: Quickly create PC4 maps of the Netherlands

I just released a new small hobby project: map-nl

[Github](https://github.com/fpgmaas/map-nl)

It is a Python package that helps users quickly create maps of the Netherlands at the Postal Code 4 level. Nothing groundbreaking, but fun to develop and hopefully useful to some nonetheless. For example, creating a choropleth map of the Netherlands becomes as simple as:

import pandas as pd
from map_nl import ChoroplethMapNL

df = pd.read_csv("https://raw.githubusercontent.com/fpgmaas/map-nl/main/data/woz-pc4.csv")

m = ChoroplethMapNL(geojson_simplify_tolerance=0.0001).plot(
df,
pc4_column_name="pc4",
value_column_name="WOZ",
legend_name="Average WOZ Value"
)
m.save("map.html")

Curious for your thoughts, please let me know if you have any feedback!
