How to validate the fields in the json body in DRF?

I'm using in my project Django and DRF. I'm trying to validate the json body of the request data is the exact that I'm expecting:

correct json:

{
"name": "john"
}

incorrect json

{
"name": "john"
"lastname": "doe"
}

If I send the second one (incorrect) is still working and creating objects in the DB.

I want to avoid this behavoir.

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!

Flask app rendering only base page without extending/dynamic content in all cases.

Please bear with me as I'm a complete beginner in Web Development and recently started Flask.

@app.route('/', methods='POST','GET')
def index():
if request.method == 'POST':
{stuff}
try:
{stuff}
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?

Do any of you have interesting talks you can recommend?

Adding Virtual Environments to Git Repo

At work, the engineer in charge of writing python automation tests includes venvs (both linux and windows) in the git repo. His reasoning is that people will have to download the specific python version we are using to the write code anyways; this way when we select the interpreter (which should already be symlinked to the default global python interpreter) all the packages we use will already be available (and auto-updated if necessary when rebasing).


This rubs me the wrong way, I still assume the best and most pythonic way of working is to create your own local environment and installing the packages using a requirements.txt file, possibly adding a git hook to automatically call pip install every time you rebase.

What do you guys think?

Made a Free Proxy Rotator library

Hello there,
I made a free proxy rotator library that scrapes and validates proxies from freely available sources and rotates them. Integrates well with requests library. Should be helpful for web scraping. Check it out at https://github.com/sachin-sankar/swiftshadow.

Monitor flask app for HTTP status codes and access

What are some open sources tools available to monitor my flask app?

Goal is to monitor access, HTTP status codes, etc.

Better if it can be integrated with Grafana or some observability tools out there.

How can we use the MVC pattern in flask?

I am interested in improving my programming in flask and I would appreciate some advice about how to conform to a model-view-controller (MVC) pattern in flask. I am unclear about which of the MVC components map to those that we commonly see in flask (views/routes, models, templates, etc.) and could use some feedback.

I was thinking of creating:

routes.py: where the `@bp.route` decorated functions go
controllers.py: functions that get called by the decorated route functions and bring together the views.py and models.py functionality to return a view to the front-end
views.py: for returning JSON representations and rendering HTML templates ready to hand back to the front end
models.py: for managing database models.

The following is an example - it isn't from a real app and probably won't work as it is. I am just using it to illustrate my thinking:

routes.py:

@peoplebp.route('/api/people')
def getpeople():
return controllers.getpeople()

controllers.py:

def getpeople():
people = models.Person.query.all()
return views.renderpeople(people)

views.py:

def renderpeople(people):
people = p.name for p in people

Flask-Session not working with 2.3 removing sessioncookiename

Like the title says sessioncookiename was removed from 2.3 and Flask-Session uses that, Flask-Session hasn't seen any updates in years so I don't think their gonna fix it on their end. I've seen a fork of it called flask-session2 but don't really know if it's trustworthy. Any ideas?

from flask import Flask
from flaskrestful import Api, Resource

api = Api(app)

class HelloWorld(Resource):

Use AWS Elasticache Redis as Celery Broker?

So we're using AWS to deploy our project, and using Celery for Event Driven Architecture, so celery workers are always up and running.

We wanted to use Redis as a broker, since SQS has no monitoring support from either Celery or Celery Flower. We tried using AWS MemoryDB Redis as broker, but were unsuccessful as Celery at the moment does not support clustered Redis architecture. So now we're using Elasticache Redis as the broker, but the AWS docs says that Elasticache is not persistent, and data loss might occur if the primary node fails, which means that some messages might be lost which would be really hard to recover.

So my question is that is Elasticache is a wise choice for using Redis as a broker, or we should look at something else?

Also, if someone here has used Elasticache Redis as their celery broker, please let me know your experience and if you would recommend it.
