do any of you have experience with flask? I am working on making a header for my website and I want to be able to click on it and it to take me to other pages (like and "about" page) but I can't figure out how to make buttons embedded links. Do any of you know anything about how to do that? This is the first thing I've done in flask

@glacial tapir I was just gonna send a message about Flask too. I'm curious to know how your website turns out. I have a college project that I have to work on with classmates. We are noobs when it comes to web development.

[glacial tapir]

yeah I've never done web development before so things are going pretty slow

[ocean gull]

There are two YT playlists that do tutorials on Flask. one is codemy.com and the other is by Corey Schafer

[versed python]

yeah I've never done web development before so things are going pretty slow
@glacial tapir I don't have experience with Flask, but I am pretty sure they must have an official documentation. Your specific problem is a common use case, so I'm sure it's mentioned in the Flask documentation.

[ocean gull]

https://flask.palletsprojects.com/en/1.1.x/ this is the documentation i will have to reference

[glacial tapir]

I've been looking through flask documentation and haven't found anything yet

yup @ocean gull that's the official documentation

[strange briar]

hey guys, can anyone explain me how can i use email to authenticate in django ? I created a class of users based on AbstractBaseUser

class Customer(AbstractBaseUser):
    first_name = models.CharField(max_length=100)
    middle_name = models.CharField(max_length=100, blank=True)
    last_name = models.CharField(max_length=100)
    email = models.EmailField(max_length=255, unique=True)
    phone_number = models.CharField(max_length=20)
    date_of_birth = models.DateField()

    def __str__(self):
        return f"{self.first_name} {self.last_name}, {self.email}"

[native tide]

how can i put the box in the middle?

[native tide]

@native tide easy

use flexbox

display flex: Justice-content: center

where do i put it?

<style>?

yeah

ok

css

wut

this?

no

wait

.classname{
display: flex;
justify-content: center;
}

?

sorry i annoy

nvm i got it

[static night]

@native tide but how I can get discord username etc.?

[native tide]

@native tide but how I can get discord username etc.?
@static night well I use flask-discord (flask) which is easier for what I need to do

but with DJango im not sure

[distant trout]

can someone help me fix this? it seems like card itself is moving on hover. I only added in border on hover.. and it still does the same thing without a border

[native tide]

Hello how can i make flask serve the backend of react?
here is my repository https://github.com/happyperson10/flaskreact.
if you want to help me ping me.

[strange briar]

Hello how can i make flask serve the backend of react?
here is my repository https://github.com/happyperson10/flaskreact.
if you want to help me ping me.
@native tide You need to make a REST API or a GraphQL, allow django CORS and fetch the data to your react-app from your flask-app
In other words if you don't know anything about these you have a long road of things to learn

[native tide]

alright what should i start with?

@strange briar

[strange briar]

at first you should learn djangorestframework

[acoustic oyster]

django rest framework

flask

[strange briar]

and then a JS framework of your choice for front end like axios

oh yea indeed

he's using flask

maybe this https://flask-restful.readthedocs.io/en/latest/ ?

[acoustic oyster]

but yes. For my django react app, I allow django to act as ORM and it acts as my api. My React app then receives this data and displays it

here is an example with my api https://vagabondnovel.us/api/

and here is the site that is using the api https://vagabondnovel.us/home/chapters/1

this is how it should be structured. The front end is React and axios

[strange briar]

Hey NativeLinux maybe you can help me with something

[native tide]

ok thanks guys

[strange briar]

do you know how to implement an AbstractBaseUser in django ?

I would like to add more fields to user model

[acoustic oyster]

yeah, what do you need help with?

[strange briar]

and login with email

I've done dis

    first_name = models.CharField(max_length=100)
    middle_name = models.CharField(max_length=100, blank=True)
    last_name = models.CharField(max_length=100)
    email = models.EmailField(max_length=255, unique=True)
    date_of_birth = models.DateField()

    def __str__(self):
        return f"{self.first_name} {self.last_name}, {self.email}"

but i don't know how to setup the login via email

[acoustic oyster]

you can also use AbstractUser instead if you would like all the built in stuff, such as admin, staff, name, email, etc

[strange briar]

Yes but i've seen that it's not good for my case, like adding more fields and stuffs

i don't remember exactly why i worked on it yesterday

but AbstractBaseUser was the one that would fit my needs

AbstractBaseUser also has the authenticate and basic things i would need no ?

i'm trying to build an e-commerce website that's why the class is called Customer

[acoustic oyster]

yeah, abstractbaseuser has auth as well.

I recently implemented an AbstractBaseUser in the code jam, we used the default django.contrib.auth.views.LoginView to manage our logins though

[strange briar]

I see

and so the login was still done via username and password ?

[acoustic oyster]

yes.

you may need to create a totally custom login form/view that will accept an email and check that the password is correct, then authenticate

[strange briar]

I will make the front with react and graphql

[acoustic oyster]

I am also using graphql 😄

[strange briar]

xd

[acoustic oyster]

this is the exact code, but we are using AbstractUser

def resolve_login(_, info, data):
    request = info.context["request"]
    user = authenticate(username=data["username"], password=data["password"])

    if user is None:
        return {
            "status": False,
            "error": "Invalid username or password",
            "user": None,
        }

    # User is valid
    login(request, user)

    auth_token = generate_user_auth_token(user)
    return {
        "status": True,
        "token": auth_token.token,
    }

[strange briar]

i find it more appealing i learned the basics of rest framework and then i learned also about graphql and decided i would learn and implement this instead

[acoustic oyster]

from django.contrib.auth import authenticate

[strange briar]

thank you 🙂

[acoustic oyster]

graphql is way better imo haha

[strange briar]

interesting

yea clearly xd

50 endpoints and useless data when you fetch is really meh

it's also more friendly to learn tbh

[acoustic oyster]

I hope this helps, I imagine you can replace username with email and it will authenticate?

[strange briar]

yes that's what i was thinking about 🙂

[acoustic oyster]

I found REST easier to learn, but I have been using rest apis for some time, I had never used graphql before working on this project

[strange briar]

I see

maybe yes since it's more

we can say restraining

[acoustic oyster]

yeah, haha

[strange briar]

like you know what your endpoint is and which data it's gonna provide

i'm not very experienced tbh but your example definitely give me some clues so i'll do more researches on this, thank you NativeLinuxUser 🙂

[acoustic oyster]

np, I hope this helps

[strange briar]

yea it does thanks 🙂

[hallow jacinth]

Could someone that has used git before help me in #🤡help-banana real quick?

[rare nebula]

yo idk if this is the right channel but if anyone has experience with regex can you tell me why this

print(re.search("correct_response\">Brazil</em>", "correct_response&quot;>Brazil</em>"))

is coming up with None as the result? I'm just trying to find a string using the exact string as the regex (escaping 2 times)

[cobalt cedar]

Can someone suggest a source to learn django like video tutorials?

[dapper tusk]

Corey Shafer has a nice series

[lethal orbit]

Hello how can i make flask serve the backend of react?
if you want to help me ping me.
@native tide I would recommend ariadne tbh. More modern than REST. It also has flask support. https://ariadnegraphql.org/docs/flask-integration

With apollo client on the front-end side.

Anyone with experience implementing Marketing API/Conversions API using Facebook Business SDK for PY?

[native tide]

Hi guys

I'd like to pass in a Jinja2 expression into a WTForms input placeholder.

WTForms input:

{{ form.email(class="formfield", disabled=True) }}```

I want it to have a placeholder="{{email}}". I can't find how to do this. Does anybody know what to do here?

I've found a workaround by just replacing it with a div that has the exact same look as a formfield, but still, I'd love to know how to do this.

[native tide]

@native tide you wanna a placeholder name ="Email"?

[cold socket]

Hey all I have this query in Flask to retrieve data from my database using the id key. @app.route('/api/store/<id>', methods=['GET']) def get_store(id): store = Store.query.get(id) return store_schema.jsonify(store) How can I query it with another parameter instead of id such as a unique string

I have 3 columns: id, name, date.

[native tide]

@native tide I want the placeholder to be a jinja2 variable {{email}} which I pass from the flask route

[cold socket]

I want to query it using name which is unique

[native tide]

@cold socket You can do Store.query.filter_by(name=name) etc

[cold socket]

@native tide Now that I think about it. Does name have to be a primary key?

[native tide]

primary key only can be true

oh id name?

no, your ID should be the primary key.

say you had a user in your database with ID 1, and name 'Jeff'

You can do database.query.filter_by(name='Jeff') and you'll get his object

id shoule be primary key

it's required

then you can manipulate the object to get the info you need

[cold socket]

Ah okay that makes sense. Thank you so much!

[native tide]

No problem! 🙂

No problem

Has anyone had the same issue?

[fierce hare]

Hello all. Today I stumbled upon this https://github.com/robinhood/faust and was wondering if someone could maybe explain a real world example maybe of how this is useful? I read it multiple times and tried to find projects that use this with flask or sanic (which is what I'm using) but failed to do so.

How would this be added to sanic (I use sanic to build a REST API for an note taking app that I'm making) and how would it benefit me?

[noble star]

How does a person make tests for web aplications like flask?

Or web stuff in general?

[valid orbit]

Hey @noble star, That's a pretty broad question. Can you narrow it down at all?

Most web frameworks offer support for testing as part of the framework.

[agile ermine]

Flask seems to use pytest as a base https://flask.palletsprojects.com/en/1.1.x/testing/

[valid orbit]

For example, in Flask you have access to a test client as an attribute of your flask app. app.test_client() gives you this object. You can use it sort of like a web browser to make get/post/put/delete requests

[agile ermine]

Postman can also be used to test responses from an api

[valid orbit]

yep.

Tests that send a request to some endpoint in your web application are a great place to start.

You can test that the expected urls exist, and that the right kinds of HTTP methods are available (and unavailable)

[agile ermine]

Yis. And expect whatever status code and the output for the response as well. And also see the response time

[valid orbit]

You can test logging in and out, and whether a user has to be authenticated to access a particular endpoint too

If you want to go beyond that, most web applications have lots of classes and functions in them as well. And in most cases those can and should be unit tested.

[noble star]

Cool Thanks @valid orbit that is what I needed

[sly canyon]

Hi guys, I have the following environment variables set on .env / .flaskenv meant to use it when I run my web app on localhost

TESTING=True
FLASK_ENV=development

But, I'd like to set

TESTING=False
FLASK_ENV=production

Whenever I commit and deploy changes through git push heroku deploy:master. Meaning that if it's not running local, it would change those variables.
Having to manually change those variables everytime I commit leaves room for an additional human vulnerability (which is me forgetting to change those, which would enable a blueprint with test routes that I wouldn't like to be deployed nor allow those endpoints to be scraped and displayed on SERPs)

[versed python]

you can use environment variables and set them on your heroku server Accordingly. You can also use pre/post commit git hooks. I suggest you try the first one.

[sly canyon]

@versed python I do commit and deploy my .envand .flaskenv files to Heroku and load them using dotenv.load_dotenv when I initialize my app using config.py. That's exactly the issue here, I want to force those changes in case I forget to change these environment variables when I'm testing stuff locally.
P.S: Will read about git hooks, never heard of that.

[agile ermine]

You shouldn’t have to commit the .env files to Heroku

[versed python]

I think you should use environment variables instead of .env files. That way you can have different values for different environments. then you can do something like SECRET_KEY = os.environ.get('SECRET_KEY').

[agile ermine]

If you go on the app’s settings in Heroku, there are environment variables you can easily set. It will work the same way with load dotenv

[versed python]

You shouldn’t have to commit the .env files to Heroku
@agile ermine yep, .env files are supposed to be developer specific. Infact if you look into the default .gitignore file that github provides, you will see .env would be included there.

[agile ermine]

So locally, keep the .env file. But don’t push it to github. You can just adjust the environment variables on Heroku and it will work the same way

Exactly! Especially if you make your repo public too

[sly canyon]

I think you should use environment variables instead of .env files. That way you can have different values for different environments. then you can do something like SECRET_KEY = os.environ.get('SECRET_KEY').
@versed python Yes, I think I have this going on here on my config.py file

[worn rapids]

^ agree

[sly canyon]

If you go on the app’s settings in Heroku, there are environment variables you can easily set. It will work the same way with load dotenv
@agile ermine Will try

[versed python]

If you go on the app’s settings in Heroku, there are environment variables you can easily set. It will work the same way with load dotenv
@agile ermine yep this is the correct way

[sly canyon]

I am sure that I have added .envand .flaskenv to gitignore, but I've stopped to deploying my app to github and I'm commiting changes directly to heroku, not sure if Heroku looks for a different .gitignore file now that you have mentioned it.

Oh, shoot, seems like I have not added .envand .flaskenv files to .gitignore, I'm just checking it right now. I may have deleted it last time I have deployed it to github

[versed python]

Heroku works using the basics of git, so it follows all rules of standard git. So yeah, it looks for .gitignore too.

[sly canyon]

Yes, I'm sure now that I'm commiting those files after seeing the variables

Seems like I have to create a whole lot of variables there

[agile ermine]

Yes, you would just set those variables there but shouldn’t commit your .env file as that might contain sensitive data

[sly canyon]

Indeed, all my integration keys, tokens, etc. are stored there

Thank you guys @agile ermine @versed python @worn rapids , I think I've everything sorted out now. Tomorrow I will deploy to test if everything is working properly

[agile ermine]

👍 happy to help!

[worn rapids]

i didn't do anything haha, but excited for u!

def fetchAllProductStock(self, productID):
    return self.query.filter_by(productID=productID).all()

inside this table is a row called item, how can I do something like:

def fetchAllProductStock(self, productID):
        return self.query.filter_by(productID=productID).all().productName

I want to first all items productNames inside this query

This will work:

def fetchAllProductStock(self, productID):
        query self.query.filter_by(productID=productID).all()
        names = []
        for item in query:
            names.append(item.productName)
        return names

But it seems long. Surely there must be a way to do it in one line with sqlalchemy ?

[vestal hound]

def fetchAllProductStock(self, productID):

inside this table is a row called item, how can I do something like:

        return self.query.filter_by(productID=productID).all().productName

I want to first all items productNames inside this query
@past cipher [item.productName for item in self.query.filter_by(productID=productID).all()]

incidentally, in Python you should use snake_case instead of camelCase

[past cipher]

yeah I always forgot to use snake case, a couple of people have mentioned this to me, when i'm quickly writing code I mix them up and end up eventually fix it

will try your above code now

works great @vestal hound , thanks!

[vestal hound]

np

works great @vestal hound , thanks!
@past cipher actually I think you might want to remove the .all()

it should stll work

[past cipher]

yep you're right, no need for all()

[vestal hound]

yep you're right, no need for all()
@past cipher there's a difference

.all() turns it into a list

so there's an extra list created (less efficient)

[past cipher]

seems to turn it into a list regardless

[vestal hound]

no

.all() makes a list, then the list comprehension makes another list from it

whereas the Query object is an iterator (doesn't produce values until necessary)

so only one list is ever created

(the result)

[frozen python]

[frozen python]

Should pages, be it’s own App in Django?

Or is just adding them to a templates folder good enough?

[versed python]

different parts of your website should be different apps. For example, you'll probably want to separate user handling into a separate app called accounts and blog posts into a separate app called posts. So to answer your questionsl, no, each page will generally not be its own app.

[west jay]

Hello! i'm interested to learn django, and crossed these two tutorials
https://developer.mozilla.org/en-US/docs/Learn/Server-side/Django
and
https://docs.djangoproject.com/en/3.1/intro/tutorial01/
Which one is better to take?

[versed python]

The second one. Actaully both are good but its generally more preferable to learn a framework from its offiial docs @west jay

So yeah go with the second one

[west jay]

thanks!

[wraith prawn]

hey guys - completely new to django (fairly new to python).... anyone able to help with getting a chart to display when i runserver? it shows when i run locally pasting the path into chrome

ive found a few different things on google but couldnt resolve (using window.onload =function ete, also found about some google security issue, but couldnt figure that bit out)

[versed python]

what kind of a chart do you want? @wraith prawn

[wraith prawn]

line / bar charts

from what ive just read its to do with having the location hardcoded ? im watchign some vids now to try understand it a bit more

[versed python]

Do you know how to use some kind of graphing library (eg Matplotlib or Plotly)?

[lethal orbit]

I would recomment something client-side like Chart.js and passing the data as JSON.

https://www.chartjs.org/

[versed python]

I had a lot of success with plotly too, especially if you want to make the graphs using python

[lethal orbit]

Not familiar with Plotly, but matplotlib's API is... special lol

Great project, but hard to configure.

[versed python]

yep

[wraith prawn]

@lethal orbit so I tried using chart.js, I have a separate JS file that has my charts in it with the data. should that instead be passed directly into the HTML ? (ill also look this up, not after someone doing all the work for me ! )

[lethal orbit]

Mostly depends on your project structure. I usually use Quasar/Vue.js as a client, and have a Django REST or GraphQL API.

[versed python]

wait you use vuejs?

[lethal orbit]

I think a JS file would be fine.

Me, yes. Vue.js is love.

[versed python]

Oh god. How do you get it to run? I am having so many issues... Can you tell me where you learned how to integrate django and Vue together?

[lethal orbit]

Easiest/best way I find is docker-compose, nginx, one node image for Vue, one python image for Django, and ariadne for GraphQL (back-end) and apollo-client on the front-end.

[versed python]

Isin't Vuejs supposed to be the front-end?

I already use docker-compose to run a python container, a nodejs and a third one for postgresql @lethal orbit

[lethal orbit]

Yup, its front-end.

if you want, we are working on an open-source project using Docker-compose, Django, Quasar, Vue, Postgres... you can always join, and look at the code.

Here, I made the repo public: https://gitlab.com/djangocities/djangocities

So you can see the code without joining.

[versed python]

docker-compose -f docker-compose.yml -f docker-compose.dev.yml up Why exactly did you use two different docker-compose files here?

But yeah I will try it out, thanks @lethal orbit

[lethal orbit]

NP. If you want to join us in working on it, feel free (though we're kind of busy with pyweek this month) to DM or ping me.

We have a fair bit of experience and you can definitely learn something.

docker-compose -f docker-compose.yml -f docker-compose.dev.yml up Why exactly did you use two different docker-compose files here?
@versed python Maybe not the best / most DRY approach, but I usually split those up into different environments that have different needs.

This one only has a dev stage for now, but it's a nice way to then set up a staging environment, and a production one, etc.

[versed python]

well, I will be looking into the progress every now and then. I am too inexperienced to contribute though.

[lethal orbit]

Nonsense 😄

How do you get experience if not by working on projects?

[high herald]

So uh, I got a pretty weird email and I don't know how to best respond to it

I sell collectible trading cards online, and a customer randomly registered a whole bunch of shady sounding URLs related to the product and wants to "help" us by redirecting them all to my store until he figures out what he wants to do with it.

Is this something I can prevent? This guy sounds like a massive headache based on the rest of the email and I don't know enough about SEO etc to even begin to guess if this is even an issue for me.

[rancid lintel]

Is there a simple way to show a modal in combination with a specific route?

-> show posts list

/post

-> show modal (on top of the posts list)

/post/:id

[native tide]

@high herald Probably a scam. Block them.

No point in wasting your time for an "If"

[high herald]

What do you mean by block them?

Is that a thing I can do? If a random person wants to do a 301 redirect from some random site they purchased to mine, is that something I can block? Or are you referring to just blocking their email so that I don't get more of these messages

@native tide

[native tide]

Block their email

If you think something is suspicious enough that you had to ask other people, i think its safe to assume its too suspicious. If you get an email from a stranger giving you a good deal, whose email has a link, avoid them.

Unfortunately, I don't think this is a scam. I sell trading cards for a popular card game and this is a regular customer.

and customers -constantly- decide they want to start a youtube channel, do a podcast and pull similar things like this all the time

[native tide]

hmmph

[high herald]

That being said, I've never had a customer just decide they want to buy a bunch of urls and 301 them to my website

[native tide]

how long have you been doing this?

[high herald]

It costs them money and as far as I understand, it does nothing.

I don't know, 16 years? I couldn't even tell you when I started

[native tide]

okay then if this is the first time you got such a request in more or less 15 years

[high herald]

This is really straying off course of the question I was intending to ask

If we can just abstract away my situation for a moment

What prevents me from registering www."somethingreallyoffensive".com and redirecting it to apple.com or something

and if that even matters if some random stranger does this

[native tide]

I don't think theres much that prevents you from redirecting a person from www.offensiveword.com to apple.com

[versed python]

Don't quote me on this, but I think django can detect which host is requesting its website (hence the ALLOWED_HOSTS setting in settings.py). Maybe you can use that to redirect users?

@high herald

[jagged lark]

Yes, it is a request header, Host

[versed python]

I think i am majorly incorrect though

[jagged lark]

Nah, you're right actually

[high herald]

Ah, that's helpful. Thank you

I created question and answer website using django I stuck on How I can associate each question or answer to a given comment in django models together with votes.

[versed python]

Link it here so that someone can help you

Ah, that's helpful. Thank you
@high herald even if I am, i dont see how that's gonna help your particular use case?

[high herald]

Perhaps I misunderstood what you were trying to communicate with me. It at least gives me a reasonable thread to start my own research

I was under the impression that there would be an option somewhere so that I could prevent a redirect, somewhat analogous to sites that disable hotlinking. But given your follow up, I guess this is not the case.

[prisma jackal]

How can i implement vote, comment section reletes to a question and answer in django models?

[lethal orbit]

How can i implement vote, comment section reletes to a question and answer in django models?
@prisma jackal Add a vote model with a UniqueConstraint on user, question, with a foreign key to question

and a Comment model with a foreign key.

[prisma jackal]

What is uniqueConstraint @lethal orbit

[versed python]

I feel like you're a beginner. Have you completed any django tutorials? @prisma jackal

[prisma jackal]

@versed python yes

I just started, this is my third project

[lethal orbit]

Google django UniqueConstraint 🙂

'user' is a DB row of 'User'. It has a relationship to another DB through the variable 'profileam'.

By doing user.profileam, it shows a row in the other DB. But it's a list, and I can't access any data in the other DB such as name.

Am I understanding this right? How could I fix it?

You just need to add a UniqueConstraint in class Meta

[lethal orbit]

Is it possible to make async requests with requests library? And if not what is the best library for them
Haven't used it, but have heard good things about httpx: https://www.python-httpx.org/

There's also aiohttp: https://docs.aiohttp.org/en/stable/

I need to get in on that async train.

[limber laurel]

Could anyone help me understand, how does this work?

[lucid vine]

@lethal orbit yeah I am currently making an API and I gotta make multiple requests somewhere to return a result and without async it is taking too long to be acceptable. Will try httpx, just gotta wrap my head around this as well https://docs.authlib.org/en/latest/client/httpx.html

[lethal orbit]

Could anyone help me understand, how does this work?
@limber laurel poorly xD

It creates a WebSocket with a string concatenation.

Could do that with template literals which look better (and is usually more efficient, at least in python, not so sure about JS). Edit: apparently it is faster in some engines, but not all.

const chatSocket = new WebSocket(`ws://${window.location.host}/ws/chat/${roomName}/`);

In Django website static files like css, images and sounds works on my localhost but they are not working on my aws windows server?
@fast basin do you run python manage.py collectstatic and serve them properly? Django only serves static files if DEBUG is True

https://docs.djangoproject.com/en/3.1/howto/static-files/#configuring-static-files

It's not meant to be used in production.

Can someone explain to me the advantage of using websocket? I have this Javascript which works fine:

function runStripePayment(productID, stock){

            }).then(function(responseJson) {
                var clientSecret = responseJson.client_secret;
                var form = document.getElementById('payment-form');
    
                form.addEventListener('submit', function(ev) {

                }).then(function(result) {
                    if (result.error) {
                    console.log(result.error.message);
                    document.getElementById('stripe-error').style.display = 'block';
                    document.getElementById('stripe-specific-error').innerHTML = result.error.message;
                    } else {
                    if (result.paymentIntent.status === 'succeeded') {
                        document.getElementById('s-token').value = clientSecret;
                        document.getElementById('user-delivery-email').value = document.getElementById('delivery-email').value;
                        document.getElementById('form-productID').value = productID;
                        document.getElementById('purchase-check').submit();
                    }

            });
            });
            });
        }

However, I was told I should really be using websockets, as this JS code could be manipulated by a malicious user. I just don't understand how a web socket would work

considering the websocket would should the full paymentIntent data

hi does anyone here know js?

<script type="text/javascript"

can someone help me with what this code means

[past cipher]

its a script tag linking to code.js file

[native tide]

so basically what happens if u type it in smthn like vsc? @past cipher

[past cipher]

vsc ?

[native tide]

yea

what is that

[native tide]

like what is the output?

visual studio code

its a code editor

ohhhh

so if u have a file name code.js

you can import it to ur html file using that code?

@past cipher

not sure if its best option for your needs, but always useful to know when dealing with db

[versed python]

anyone good with heroku apps? I am having db trouble xd
@hallow jacinth yeah?

[maiden kraken]

@past cipher thanks a lot man, really appreciated your help and spending time to help beginners!

[hallow jacinth]

lets go to #help-falafel

[versed python]

guys I need a help in js. What does const { data, id } = payload mean? I mean what does that syntax do?

lets go to #help-falafel
@hallow jacinth sure

[dapper tusk]

@versed python it means that payload is an object with keys data, id (and maybe more), and those 2 keys get set to variables of the same name

[versed python]

SO it is extracting it basically?

[dapper tusk]

Yeah, pretty much

[versed python]

is this vanilla js or is it something like idk es6? @dapper tusk

[dapper tusk]

ES6 is vanilla JS

It is probably an ES6 feature

[vague ibex]

Vanilla JS is just normal JS. That's it.

No need to worry about it lol

[versed python]

So that is normal javascript? const { data, id } = payload

[vague ibex]

I've seen people struggling to understand what is vanilla JS. To make the long definition short, Vanilla JS = normal javascript

yeah

[dapper tusk]

Yep

[versed python]

since i have never seen it in my own js basics courses anywhere

[dapper tusk]

You can do it in a browser console

[vague ibex]

Actually, the name was given to it simply to prove that Javascript is a powerful language even without any plugins

[versed python]

oh yeah, ik it works. I just wasn't sure how

doesn't Vanilla mean default? @vague ibex

[vague ibex]

yeah normal javascript is default

as it does not include any plugins initially

[dapper tusk]

Since ES6, JS is actually useable without external libraries, though they still help

[vague ibex]

^

[versed python]

so for example there is a module called axios. Is that a plugin? or vanilla?

[vague ibex]

Since ES6, JS is actually useable without external libraries, though they still help
@dapper tusk JS is actually believed to be pretty powerful. The name "Vanilla" is just used to make it look cool xD

so for example there is a module called axios. Is that a plugin? or vanilla?
@versed python There's a difference between module and plugins

What is "Vanilla JavaScript"? ... "VanillaJS is a name to refer to using plain JavaScript without any additional libraries like jQuery. People use it as a joke to remind other developers that many things can be done nowadays without the need for additional JavaScript libraries."

^ for clearing ur doubt regarding vanilla js

its a source from google

[versed python]

that makes sense

[dapper tusk]

Vanilla is a common term for things with no extensions

[vague ibex]

vanilla ice cream kek

[versed python]

Vanilla is a common term for things with extensions
@dapper tusk this confused me again

[vague ibex]

https://stackoverflow.com/questions/8519021/what-is-the-difference-between-module-plugin-and-component-in-java#:~:text=A module a quite generic,application to provide new functionality.

check this one.

[versed python]

Vanilla js is batteries included or not?

[vague ibex]

You'll understnad

[dapper tusk]

Oops, no extensions, typod

[vague ibex]

lol lakmatiol

[dapper tusk]

I am terrible at not skipping words when on a phone, sorry

[versed python]

just use text to speech duhh

[dapper tusk]

That would wake the dog up

[versed python]

(actually please don't it's horrible)

[vague ibex]

IgnisDa, did u get ur doubt cleared?

If not, tell me

[versed python]

yeah I did pretty much.

[vague ibex]

Its nothing to worry about lol

Vanilla JS is just plain js

[versed python]

but I still dk why you said plugins and extensions are different

[vague ibex]

o,o

i dint say that

A plugin is, like its name says, a piece of software that you can plug into an application to provide new functionality. Plugins usually implement well defined API's and are reactive (that is, they provide services that the main application can use).

This is what stackoverflow says

[versed python]

oh

[vague ibex]

You can refer to the link I sent earlier

https://stackoverflow.com/questions/8519021/what-is-the-difference-between-module-plugin-and-component-in-java#:~:text=A module a quite generic,application to provide new functionality.
@vague ibex this one

This gives a clear explanation in smooth words

[versed python]

and this "component" referred to here. Is that different from Vuejs components?

[vague ibex]

be it java or javascript, plugins and modules are terms in general

and this "component" referred to here. Is that different from Vuejs components?
@versed python What do you mean by Vuejs components?

A component is any piece of software designed to be reusable.

[versed python]

Oh it is a js framework

[vague ibex]

so, component is just like a software

lol

yea, ik its a framework

A framework may/may not be a software

[versed python]

A component is any piece of software designed to be reusable.
@vague ibex Yeah thats what Vuejs decribe componenets in the docs too

so django and vuejs are frameworks right?

[vague ibex]

yep

[versed python]

thank you

LEGEND

[vague ibex]

No worries ^_^

My objective is to help people clear their doubts lol

[versed python]

how does one get so much knowledge from though?

[vague ibex]

Whenever I have a doubt of my own, I just try my best to get a solution from it

[versed python]

how long have you been doing this stuff?

[vague ibex]

how does one get so much knowledge from though?
@versed python Its like what u acquire

Well, I'm 14 (turning 15 this year)

how long have you been doing this stuff?
@versed python I've started programming casually at 11

[versed python]

that's cool, I am 18

[vague ibex]

I'm more inclined towards web development

[versed python]

what I meant was, how long have you been dabbling in web development and stuff?

[vague ibex]

so its like 14-11 , that gives 3

[versed python]

and what languages do you know other than python and js?

does one need to know anymore for web development?

[vague ibex]

Yea

Web development is a constantly evolving tech ngl

[versed python]

other than HTML CSS

[vague ibex]

Its like you know JS today, and a new cool language comes up tmrw

you need to keep pace with the tech

if u dont, you get beaten in the race by other web devs

It actually depends on the work ur gonna do

Learning more is always better

But you need to learn the things carefully and clearly

there is a wide range of frameworks

[versed python]

what exactly do you mean by learning more? Learn more languages? Frameworks?

[vague ibex]

• langugaes

both languages and frameworkjs

frameworks*

and tips and tricks, you know

[versed python]

whooo I have a lot to learn lol

[vague ibex]

It is better to have a good grasp on the cool techs

suppose your client tells u to make an E-commerce site, you can have an idea of what to use and what to not

I can make a simple website out of html, css and js for e commerce purposy

purpose*

But if i want it to be a legendary website(Exaggerating ) , then i would prefer django, react and such things

[versed python]

but its probably easier to do with Vuejs or something?

[vague ibex]

There r plenty of technologies in the market

anything can be done to make an e commerce website

your sense/idea is what it requires

[versed python]

I heard react is much more difficult than Vue. Thats why i got started with vue

[vague ibex]

if u have already learnt the techs, it will be easy to make a plan

IgnisDa, do you know js or python?

[versed python]

alright anyways thanks for helping me out. Much appreciated! I gtg now

if u have already learnt the techs, it will be easy to make a plan
@vague ibex both

[vague ibex]

ah thanks! cya! o/

[versed python]

i mean ik both py and js

[vague ibex]

happy coding! 😄

[versed python]

thanks and same to you

[vague ibex]

then it would be easier for u to move on to frameworks

yea cya o/

Hi. First of all, very sorry for the probably stupid question. I am very new to coding python.

I have created a machine learning model using python which uses a simple text input string to generate some output.

I am running this using Colab, but also locally.

I now want to deploy this project to a website using a simple HTML field and a submit button. Once the user enters some text, i want to pass this string to my external python (.py) file

Normally I do this with python using e.g. "python input.py --input "Some string".

I've been looking a little at FLASK, but i don't seem to find any good pointers on how to work with separate python files, rather than passing around arguments inline.

Any help would be appreciated, where I should start looking. Again, I am a total noob when it comes to this

good luck!

[native tide]

Can I also receive an output from that file to show on the webpage btw?

so it is kept as a variable

session

i basically want to use my python file as an API of sorts

input > output

[vague ibex]

yea i got you

[native tide]

basic i know

🙂

[vague ibex]

so you wanna take the input, apply a function on it and display an output?

[native tide]

yes indeed. Even make a file available for download

which is generated by the script

[vague ibex]

yea sounds nice

[native tide]

so lets say i input "cat" into an input field, and the function will return an image of a cat

although it is more fun than that 🙂

[vague ibex]

wow thats cool\

[native tide]

lol no

actually it will take a text as input, then generate a text to speech sound file

using a custom voice

that all works already

but the web deployment is tricky for me

[vague ibex]

btw lemme show u something rlly cool and interesting

if im using flask and i have a csv file i wanted to display

should i keep it as a csv file or convert it to SQL

[frozen python]

I’m tutorials with Django.... no one barely talks about “initiated” a class. That’s what’s been wrong with my DB of objects to show

[maiden kraken]

I think startng with csv is okay. You can always switch to sql db later

[lapis spear]

hello umm
how to add form in detailview currently i am displaying the Post model in detailview and what i want is to add a comment feature on the detailview using Comment model now i don't know how to add the comment form on detailview
can anyone help me please 😅

[versed python]

Django DetailView? @lapis spear

[lapis spear]

@versed python yes yes sir

[versed python]

From what I understand from your question, you're trying to get two different forms (since you arr dealing with two different models) into the same view. Now DetailView is a generic view and is meant to deal with only a single form and single model. You'll probably want to rethink your view and convert it to function based. Otherwise you'll have to do a bunch of subclassing and inheritance and modifications to get what you need.

Guys isn't there any way to upload a Django website to an Apache server without mod_wsgi? Cause some hosts don't have command line interface

[lapis spear]

@versed python what im trying to do is using post model to display and comment model for form is it possible in detailview?

[native tide]

ight imma code peace

[versed python]

straightforward answer is no. you will have to do a lot of modifications which will probably not be worth all the time.

[glass sandal]

Oh well

[versed python]

@lapis spear

[lapis spear]

@versed python oh yes yes thank you sir

[glass sandal]

So basically it's possible

[versed python]

use a function based view it will be much easier

So basically it's possible
@glass sandal it is but i dont see why anyone would want to go through all that trouble

[native tide]

i have a quest

this command:

[versed python]

I did it once just for the sake of learning it was useless in an actual project

how to add form in detailview currently i am displaying the Post model in detailview and what i want is to add a comment feature on the detailview using Comment model now i don't know how to add the comment form on detailview
can anyone help me please 😅
@lapis spear they need help with this

[native tide]

<script type ="text/javascript"
src ="Code.js"></ script >

so what this code is doing so if u have two files and one is a html and ur coding in the html and one is called code.js so if u write this script in the html file all of the code from code.js is basically in that script combining with the html code

is this write?

bascailly bringing a .js file inside a .html file?

[versed python]

why do you call me sir @Hello? please don't. As a general rule i use cbvs since most views are generics. when i need to do something special, i have to switch over to function based ones or write a difficult class based one. depends on the use case.

[sharp grotto]

yep

[native tide]

kk

marizuana idk if my discord is lagging but do u have a discord pfp? @sharp grotto

or not

idk if im lagging

[sharp grotto]

I don't

[native tide]

kk

thx

[sharp grotto]

xD

[lapis spear]

@versed python oh nice nice thank you mate 😅 👍

[native tide]

everytime u run a js code after the ()'s do u have to add a ;

just like:

[versed python]

glad to help @lapis spear

[native tide]

document.write("Hello World"); //do u have to add the ; in it? ```

[versed python]

everytime u run a js code after the ()'s do u have to add a ;
@native tide its not required but recommended

[native tide]

ok thx

[versed python]

most IDEs will add one by default when they format your code

[native tide]

okay

[versed python]

yeah np

[native tide]

ngl js is easier than python in my opinion

i quit python cause its too hard ):

and js is perfect

but imma learn py after i finish learning js

[versed python]

it's the other way round for me. I find js hard.

[native tide]

[glass sandal]

Python is eaaaasier than JS

[native tide]

i think js is lmao

[glass sandal]

SO much easier

[versed python]

especially all that Promise and api stuff

[native tide]

js is easier

i just started js today

and i started python a month ago

[glass sandal]

JS is easy in the first glance

[native tide]

and i dont understand while loops lmao

so now im learning js

[versed python]

any language vs language debate is pretty much useless and never gonna be resolved. It's just a developers personal preferences

[glass sandal]

Well the more programming languages you know , the easier it gets to learn new ones

[native tide]

yea

[versed python]

laughs in C++

[glass sandal]

XD

[native tide]

<script>
var price = 55.55;
document.write(price);
</script>

is it optional to add <script> ?

[versed python]

you want difficult, get down on the C bois

[glass sandal]

Yesss

[versed python]

nope

[glass sandal]

C hard

[native tide]

u have to add <script>

[glass sandal]

But

[native tide]

<script>
var price = 55.55;
document.write(price);
</script>

is it alright if i just added:

[glass sandal]

Let's see what you do with brainfuck

[native tide]

var price = 55.55;
document.write(price);

is it the same?

Let's see what you do with brainfuck
@glass sandal lmao

[glass sandal]

@native tide Is that in your .js file or your .html?

[versed python]

C hard
@glass sandal The problem with it is you have to learn stuff like pointers ajd memory addresses as part of the basics. Thats what makes it hard.

[native tide]

none

im on solo learn

lmao

[glass sandal]

@versed python I know C++ , but C is just barebones you know

[native tide]

its talking about data types and was giving an example

@glass sandal

its js

[dapper tusk]

C is nice for simple programs

[versed python]

Let's see what you do with brainfuck
@glass sandal i saw the Wikipedia page once. Needless to say, i didn't venture anymore lol

[glass sandal]

@native tide You don't need <script> in .js files

[native tide]

kk

thx

[glass sandal]

@versed python XDDDD Same

[versed python]

I know C++ too. But i have never really used it for anything major

[glass sandal]

Or like the Cow/Moo language

Me neither

[versed python]

just those small calculator programs they make at school

[glass sandal]

Yeah never used it for my real projects , just done some simple algorithm stuff + Some ncurses

[versed python]

python on the other hand is mmmmmmmmmmmm

[glass sandal]

Python is the best imo

Not by the syntax

[native tide]

how do u make a new line in js

is it also /n?

[glass sandal]

@native tide \n

[native tide]

\n

[quick cargo]

<br>

[native tide]

even for js?

[versed python]

especially coming from C++, i picked up the syntax with a day and made my own hangman with another day

[glass sandal]

Yes

[native tide]

kk

[glass sandal]

For almost any language it's like that

[quick cargo]

\n isnt used in HTML directly

unless its specifically markdown

[native tide]

what are the headings u can use in js

<h1> i only know that one

any more or em?

[glass sandal]

@versed python omg my first lang was C++ and then Python , wow similarities

@native tide You need to document.write them

[versed python]

you Indian? @glass sandal

[glass sandal]

Nope

Iranian

[versed python]

hmm

[native tide]

im muslim

i live in canada born in england my parents are from pakistan

[versed python]

i was taught C++ at school, learnt py myself. wbu?

[glass sandal]

I'm not too much into religious stuff , tho I respect them

@versed python Learned all by myself

[native tide]

i learned myself too

im not like perfect in coding

like im still learning js and py

[glass sandal]

I'm just like 14 tho

[versed python]

I don't think anyone from our generation is really serious about religion

[native tide]

but stopped py yesterdau

im 13

[glass sandal]

Good

[versed python]

im 18

[native tide]

lmao

[glass sandal]

Woah

XD

[versed python]

yep

[native tide]

i like to code cause i wanna make a buisness

i can photoshop so i wanna make a buisness where i create ads

i can video edit too

[versed python]

you should start by learning how to spell business my man @native tide

[glass sandal]

No I loved coding in the first place , cause I LOVED inventing . And inventing needs money . Coding is like inventing from scratch . That's what I loved about it

[native tide]

lmao

business

isnt it buisness ?

wait it isnt

[glass sandal]

business

[native tide]

lmao i thought it was that for my whole life

[glass sandal]

Don't get spell problems please lol

[native tide]

kk

i wont

[versed python]

I love coding since people are annoying. mostly.

[native tide]

lmao

[glass sandal]

Lol?

[native tide]

i have a quest about hacking its a pretty weird quest but was wondering

[versed python]

nah you guys are fine. people are fine when you vibe with them

[glass sandal]

lakmatiol is

gonna

tell

us

to

[versed python]

otherwise m.. mehh

[native tide]

is there a hacking lang ?

[dapper tusk]

I like coding because it is really hard to make an irreversible mistake

[glass sandal]

goto

[dapper tusk]

Though this is getting ot

[glass sandal]

@native tide Python is the best I could think of?

[native tide]

oh

is there a way to make ur own coding language using a coding language

[versed python]

let's take this to #ot0-fear-of-python

[glass sandal]

Yes

[native tide]

like using js to make a coding lang

[glass sandal]

YEsss

[lapis spear]

@versed python yo😅 how can i reference in view the currently displayed data in my detailview?

like accessing the post title in detailview

i want to fill the user and post field by current user and displayed post in detail view in my comment model is this the right solution?
def form_valid(self, form):
form.instance.user = self.request.user
form.instance.post = self.request.post.id
form.save()

this is the comment model

class Comment(models.Model):
post = models.ForeignKey(Post, related_name='comments', on_delete=models.CASCADE)
comment = models.TextField()
user = models.ForeignKey(User, on_delete=models.CASCADE)

@versed python

[versed python]

instance = form.save(commit=False)
instance.user = self.request.user 
#... whatever else you want... 
instance.save()

@lapis spear

[lapis spear]

@versed python i got an error it seems a field in comment is not filled after sent
NOT NULL constraint failed: blog_app_comment.post_id

[versed python]

well yeah you have to associate a post id to it.

form.instance.post = self.request.post.id

wait what

no

instance.post = form.cleaned_data.get('post') use this @lapis spear much easier

[lapis spear]

@versed python alright thank you 😅

[versed python]

WHO DO YOU THINK YOU ARE CALLING SIR?

Seriously tho please don't

[lapis spear]

@versed python oh i edited it sorry😅

@versed python yo this must be a silly question it seems like i don't understand much what im doing but i think its solving the problem does that count? can i proceed and just hope the as time goes i will understand it?

or should i take a rest and understand it?

[versed python]

yep that's how i do stuff. just follow blindly whatever the right way is, i end up getting it later

[lapis spear]

for example what the hell does this do?
def post(self, request, *args, **kwargs):
self.object = self.get_object()
form = self.get_form()
if form.is_valid():
return self.form_valid(form)
else:
return self.form_invalid(form)
😅

@versed python oh i see nice nice i m hoping that the more i repeat those stuff i will understand it

[versed python]

yeah

for example what the hell does this do?
def post(self, request, *args, **kwargs):
self.object = self.get_object()
form = self.get_form()
if form.is_valid():
return self.form_valid(form)
else:
return self.form_invalid(form)
😅
@lapis spear which part?

[lapis spear]

@versed python self.object = self.get_object() this one sir

the others i think i get it like getting form and checking if its valid or not

[versed python]

if you look into the source code of this particular CBV, you will find it implements a def get_object method.

@versed python self.object = self.get_object() this one sir
@lapis spear this particular line is just calling that method and associating it with the object attribute

if you have time, i highly recommend you checkout the django source code. You'll learn a lot, especially since it is well commented.

it's on http://github.com/django/django

[native tide]

can someone help me with js increment and decrement

i dont get what it does

[lapis spear]

@versed python alright thank you again mate 😅

[versed python]

yeah no issues

[frozen python]

should I have “2” URLS.PY files?????

One in my Project and one in my App?

[dapper tusk]

Yes

[frozen python]

Should it be the exact same routing????

[prisma jackal]

Then you include app's urls in project's urls

That is a good design in general, will help during extention of project I can say Same for the template, inside the app folder templates/app

[frozen python]

Shouldn’t the pages “for the app” be only in the app urls? Then the main HTML pages is the actual project?

[prisma jackal]

Yes

[sly canyon]

Has anyone here implemented PageView events using Facebook Business SDK?

[frozen python]

@prisma jackal I only have one “views.py” file and that’s in the app, not the main project

[native tide]

can someone help me?

var x = 3;
switch (x) {
  case 1:
    document.write(x);
    break;
  case 2:
    document.write(x+2);
    break;
  default:
    document.write(x+5);
}```

can someone tell me what this code means pls

[quick cargo]

um

in general

[frosty lion]

its kinda like an if statement?

[quick cargo]

fuck all without context

[native tide]

like whats it doing

[quick cargo]

if you mean the switch statement

[native tide]

i dont get the switch statement

im learning it in solo learn

[quick cargo]

its just doing what a block of if elifs would be doing

[native tide]

i dont get break default and swift

[prisma jackal]

Switch is more fast than if statement

[frosty lion]

its another way to write conditional statements i guess

[native tide]

so how is the output 8?

[frosty lion]

its basically doing

if x = 1:
  write x
elif x = 2:
  write x + 2
else:
  write x + 5

so since x = 3

the first two dong work

[prisma jackal]

@frozen python project urls is for handling all urls from different apps. Each app should each own urls then urls from a given app is imported in project urla

[native tide]

its js

not python

[frosty lion]

so i goes to the default

ik

but thats the python eqivilent

[native tide]

ohhh so thats what it means

what does switch do?

[frosty lion]

its a way to write a bunch of elifs

[native tide]

ohhh

how bout break and default?

[frosty lion]

default is basically the else

[prisma jackal]

Prefer switch to if statement when they are both working equally.

[frosty lion]

the switch executes anything that it matches

break will exit the switch

[prisma jackal]

Break prevents fallthrough

[frozen python]

@young saddle so I need to update 2 files then? urls and views?

[frosty lion]

is that django?

[prisma jackal]

@frosty lion yes

[frozen python]

Yes

[frosty lion]

okay

[frozen python]

Why????

I have one project that I only have one views.py and it’s in my app, not main project

[frosty lion]

u should have a templates folder for ur html

i think its called static

only apps should have views im quite sure

ur folder with settings and stuff doesnt have views?

[frozen python]

@frosty lion no, that’s a picture of it. Why do I need to update 2 view files? Isn’t one good enough?

[frosty lion]

ur templates folder

seems kinda wrong

unless u changed how django will search for static files

[frozen python]

I have a products folder with detail.html in it, then it’s the other files for the pages

“Shop” is my project, then “product” is a app. Is this setup right?

@frosty lion

[frosty lion]

products and shops seems to be at the right level

ur templates should be app sepecific

and should be inside the folder for ur app

[frozen python]

@frosty lion but, that’s not how the default layout is? Should I have the exact same urls for the shop and products?

@frosty lion SHOP is the shop is the project (main) then products is a App

[native tide]

Break prevents fallthrough
@prisma jackal wdym?

[honest dock]

Any experienced django user here?

If yes, I'm used some very complex UI made in HTML and CSS. Checked how Django forms work and it seems like it's a bit tricky to use already made forms in Django. Should I go with the trouble or just use Angular connected to DRF?

[quick cargo]

You can make your own forms you know and just send a Post request

No point using angular just for some forms

[honest dock]

Do you have any guide that shows it? Never done Django beside drf

[quick cargo]

Litterally raw Html and css will work

[honest dock]

Oh okay, and views will do the work?

Oh okay, and views will do the work?

Oh okay, and views will do the work?

Holy crap sorry

[quick cargo]

All you need on django's side is a check to see the request method and get the body if its a Post request

[honest dock]

Great. So forms can be skipped

I mean django forms

I mean django forms

[quick cargo]

I Litterally never touch any of the form generators

Making your own forms are easy enough

[honest dock]

Cool, mind if I add you to show if it's done right when i get my guy to do it?

[quick cargo]

Sure but I'm about to sleep so won't respond for a bit

[honest dock]

All good champ, thanks

[native tide]

so what this code is doing its switching day with case two day 2 is = tuesday (case 2)

switch (expression) {
case n1:
statements
break;
case n2:
statements
break;
default:
statements
}

[wicked tide]

Wrong channel (wrong Discord?). And switch statements normally will fall through (execute) the cases starting from whichever it initially matches.

[native tide]

but this is help with js read channel info

so what this code is doing its switching day with case two day 2 is = tuesday (case 2) am i right about this?

[wicked tide]

but this is help with js
Sure. You also could've just searched that statement up and not pinged a user which clearly stated that he was about to sleep 40 minutes ago.

[native tide]

lmao i never read that tho

so my bad

Sure. You also could've just searched that statement up and not pinged a user which clearly stated that he was about to sleep 40 minutes ago.
@wicked tide alright my bad about that i never read that cause my pc battery died so sorry bout that

[wicked tide]

I have no damn clue what you're asking about, being honest. I cannot decipher what you're asking. Fix your english and example.

[native tide]

do u know js?

[wicked tide]

Sure. But switch statements aren't just Javascript.

[native tide]

well im learning that in solo learn

in javascript course in solo learn lmao

wait i read ur thing wrong @wicked tide

im talking about js

[wicked tide]

Technically the switch statement you provided could go straight into Java, is all I'm saying. It might go into C# too, and a couple other languages. Still, no idea what you're trying to ask.

Does anyone here have an idea as to why this element has a height of 0? It's a Skeleton component in Vue. It might have no content inside, but it refuses to expand the height.

I've tried height: 100%, font size, min-height (as shown) etc. The element above has a height of 24px, so that can't be the problem.

[fossil swift]

PermissionError: [Errno 13] Permission denied: '/flask_session' im getting this and its infuriating, I've been tring to fix it all day.

• www-data has access to flask_session
• python directory is correctly set

[native tide]

can someone tell me whats the diff with

document.write("Hello World") and console.log("Hello World!")

[warped timber]

uh

they are very different

document.write writes html to the DOM

console.log prints text to the console

don't use document.write unless you have a good reason to

console.log is usually used for debugging

@native tide

why my validation is always getting false when I have Free tag ? https://dpaste.org/8pL4

[spark rover]

ok so I have a django rest framework app thats getting fairly big and we've got a repeated problem where we want the serializers to have different fields for normal users, admins and creation, we've ended up with viewset abstractions to make it a little nicer, but it feels like this problem must have come up many times before to other people, is there a better way of doing this?

[versed python]

maybe you can override the get serializer method on the viewset and then add conditionals there, and return an appropriate serializer there? @spark rover

[spark rover]

we already do that with some viewset base classes we defined, maybe its the only way, it just feels really hacky to have this many serializers

[versed python]

don't serializers have a get fields method?

they do https://www.django-rest-framework.org/api-guide/serializers/#dynamically-modifying-fields @spark rover

[spark rover]

I'll have a look at that, thanks

[versed python]

you're welcome

[vestal hound]

@spark rover I too had this problem!

what I ended up doing was creating a subclass of Serializer which, when initialised, takes a keyword argument allowing you to specify what fields you want

(basically)

and in particular, for my usecase there was often nesting (usually only one level, but still)

so there was also the ability to specify whether I wanted to use a child serializer or just the normal PrimaryKeyRelatedSerializer

[versed python]

Guys can anyone tell me what is the equivalent of logging that we do in python but in Javascript?

i am not talking about console.log

i actually want the data/errors to persist

not unless you have a special use case and need to do that. Why complicate things when the easier one gets the job done? import this @glacial night

yep @glacial night

[paper canopy]

So, im making a blog and im working on the profile pic feature rn. I've ran into a problem where the specified picture will show up on the web site but not the default picture I have set to

[native tide]

what module do you use for using google's oauth2?

[vestal hound]

is it a good idea to do /products/id/reviews/ or just show all reviews as a object inside product instance?
@glacial night depends, really.

on what? amount of reviews? @vestal hound
@glacial night not really

more like your workflow

for example

how often will you need

just the product?

how does this align with your conventions

for your other endpoints?

etc.

honestly this is the kind of thing

you can try yourself

and after a while

figure out

I would say both approaches are viable

okay

if you're not in a rush

I'd suggest

you pick one

and try it

experimentation is how you learn

[vestal hound]

what do you mean

[hearty shore]

hey i am very new to web development. i just wanna know where to start.

[vestal hound]

so like

double nesting basically

just

use serializers in your serializers

[sharp wraith]

what are the different coding format which sanitized the user inputs

[past cipher]

how do you show code in discord?
@glacial night

change js to py for python code

same for html, css etc
