Trying to deploy Flask app to render.com

Hi there! Flask newbie here.

I am trying to deploy a simple Flask app (just a hello world route for now) to render.com. I know that I'll need PyAudio for this project. So I already included it in the dependencies. Now when I deploy to render.com I get the following error message:

src/pyaudio/device_api.c:9:10: fatal error: portaudio.h: No such file or directory

If I understand it correctly portaudio is a C library that is needed by PyAudio. Which means I have to rely on portaudio being installed on the system I want to deploy to? Or alternatively use Docker (very limited knowledge)?

Any pointers into the right direction would be much appreciated!

EDIT:

Another thing that really confuses me is that, when I a generate a requirements.txt it adds Flask==2.3.1 as a dependency, which is current version. But the in the render.com logs I get

ERROR: Could not find a version that satisfies the requirement Flask==2.3.1 (from -r requirements.txt (line 9)) (from versions: 0.1, 0.2, 0.3, 0.3.1, 0.4, 0.5, 0.5.1, 0.5.2, 0.6, 0.6.1, 0.7, 0.7.1, 0.7.2, 0.8, 0.8.1, 0.9, 0.10, 0.10.1, 0.11, 0.11.1, 0.12, 0.12.1, 0.12.2, 0.12.3, 0.12.4, 0.12.5, 1.0, 1.0.1, 1.0.2, 1.0.3, 1.0.4, 1.1.0, 1.1.1, 1.1.2, 1.1.3, 1.1.4, 2.0.0rc1, 2.0.0rc2, 2.0.0, 2.0.1,

Flask API - CSRF and JWT implementation with frontend

Hello,

I am creating an SPA using Flask for the API endpoints. I want to secure the app using CSRF tokens and JWT tokens to prevent all types of XSS and CSRF attacks.
The front end is Vue. I am using axios to perform the requests.
I am a bit lost on how to do this implementation. When should the CSRF token be sent and how will it be stored on the frontend? What about the JWT and how to implement it with the csrf ? Too many questions and I can't seem to find anything complete online.
Does anyone have any implementation examples or knows how to do it correctly? I would appreciate any help on this matter.

Thank you.

I have a username_or_email_form is there any way to query flask-sqlalchemy query for username or email at the same query?

I could query both separately but it would make my life easier if I could query 2 possible columns and return 1 query.

Flask app with Javascript front end

I am getting status code of 200 on the server side but status code of 405 on the client side. Looking for some help here. I know that 405 means the method isnt supported but as you see in the flask app it is supported. Any help would be appreciated.

Here is my flask app:

from flask import Flask, request, jsonify
import os

app = Flask(__name__)

@app.route('/upload', methods=['POST', 'GET'])
def upload_files():
uploaded_files = request.files.getlist('files')
date = request.form.get('date')

for file in uploaded_files:
# Save the uploaded file to a folder on your server
print(file.filename)
save_path = os.path.join(os.getcwd(), file.filename)
file.save(save_path)

newbie question - df.method() vs method(df)

Hi All,

I'm not new to stats, but I am new to python. Something I'm struggling with is when to use the syntax df.method() versus the syntax method(df).

For example, I see I can get the length of a dataframe with len(df) but not df.len() . I'm sure there's a reason, but I haven't come across it yet! In contrast, I can see the first five lines of a dataframe with df.head() but not head(df) .

What am I missing? I'm using Codecademy, and they totally glossed over this. I've searched for similar posts and didn't see any.

Thanks for your help!

except youtubetranscriptapi.errors.TranscriptsDisabled:
return rendertemplate('index.html', urlfieldtext="Wrong URL")
{stuff}
return rendertemplate('index success.html')
else:
return rendertemplate('index.html', urlfieldtext="Enter Video url")

The relevant code for index.html page:

<form action="/" method="post" id="details-form">

Api vs Django views

Hey guys I’m a beginner in Django and I’m wondering is DRF api development an alternative to using default django views or are they completely different concepts? If they are different, when do I use DRF exactly?
