[dusk portal]

it provides default image (works fine /as expected)

but when i add it from a form connected to the API (backend)

it doesn't sends

default value

idk whyy

man idk why

[native tide]

Like constraints of a variable would conventionally be set with a method

[rigid laurel]

the way it works is called type hinting - it's just a feature that's supported by Python. In general when you type hint something, it is only a hint and you it could technically be any type

but pydantic does some introspection and checks the types and it will then change it's behaviour based on those

!e

a_variable : int = "not an integer"
print(a_variable)

[lavish prism]

@rigid laurel :white_check_mark: Your eval job has completed with return code 0.

not an integer

[real root]

Anyone know how to start a production server for flask?

[native tide]

So colon hinting updates annotations attibute of the object? annotations would not throw an error when the return value is of another type?

[rigid laurel]

I'm honestly not entirely sure, but in my experience I've never had to manually set __annotations__ for anything

[native tide]

Ok thanks

anyone know what this is? if the error doesnt make sense i had to remove a bit of it in order to fit it in

[thorny lake]

starts here - "DeprecationWarning: executable_path has been deprecated, please pass in a Service object"

[stiff plume]

yeah i fixed that

but now it is saying this

TypeError: expected str, bytes or os.PathLike object, not WebDriver

idk how to fix that

oh wait

from selenium import webdriver

new code

idk if i fixed it

[thorny lake]

1 sec, I have something like it

[stiff plume]

ok

do i remove

wd = webdriver.Chrome(executable_path=driver)

[thorny lake]

Also doesn't look like you changed the original error for executable path - you have to use Service() class - https://stackoverflow.com/a/70099102

[stiff plume]

yeah i saw that do you just add .service() to that line i was trying to delete

[stiff plume]

this one?

yeah ok i added it

[thorny lake]

Yeah try -

wd= webdriver.Chrome(service=Service(ChromeDriverManager().install()))

[stiff plume]

it still gives me that error

do I even need this line?

can i just delete it when i do i dont get any errors

[thorny lake]

Make sure you have the imports

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager

[stiff plume]

ok

well now I got

ModuleNotFoundError: No module named 'webdriver_manager'

ok

im putting pip install webdriver-manager

ok no more errors

[thorny lake]

nice

[stiff plume]

thx

yeah im just trying to webscrape a page for a specific image

i just need to find the image rn

[thorny lake]

are you using bs4

[stiff plume]

no selenium the website has javascript so i need to use selenium

and for some reason i cannot find the image

from selenium import webdriver
from selenium.webdriver.common.by import By

Hey does anyone know how to get a static file imported from JavaScript using a fetch request (with Django)?
I have some images I want to load as textures for this WebGL project I'm working on, and I'm trying to figure out the best way to get those images loaded.
I currently put a script tag/element in one of my HTML templates and then load the textures there so I can use the Django template syntax to dynamically load the static files, but I would like to get away from putting JavaScript directly into the HTML. I'm not sure how I can properly reference static files from another static file (JS file in this case) while having the path dynamically generated by Django on the back end.

[thorny lake]

https://stackoverflow.com/a/36355581

[topaz widget]

If it were JSON data, I was downloading, I would know how to do this, but an image seems like it would be a bit different.

[stiff plume]

Ok thx I'll take a look at it

[hollow dragon]

guys what is this? should i worry about it?

im just trying to upload my flask app to github

i read somewhere that i should ignore this but im not sure

or maybe i should use: git config core.autocrlf true

[hollow dragon]

im having issues with venv

should i convert it to 'requirements' or what?

so all I have to do is just put the requirements.txt in my github and stop worrying about the venv folder?

[inland oak]

Yes. it is useless to commit venv

it is big and will be broken once its absolute path is changed

plus it is silly to commit such bit depepdencies

have you checked its size? it takes hundreds of megabytes!

[hollow dragon]

Alright mate, thank you. I just did the pip freeze and pushed my requirements.txt to my github.

👍

[dense cedar]

Use static root inside your JS file e.g:

My STATIC_ROOT = 'static/'
so I would use it: src="static/path/to/other-static-file.js"

I'm new to using FastAPI and I'm quite impressed so far. I have a basic JWT authentication scheme kind of working. However, I have a Depends for a route where I would like it to fail if the dependency returns None.

@app.post("/highscores", tags=["highscores"])
async def add_high_score(score: int, db: Session = Depends(get_db), current_user: User = Depends(get_current_user)):
    ...

The function get_current_user checks the JWT token for validity, extracts a user id and loads the user from the database. However if the user has been deleted then the token is valid but there is no such user, so the function returns None. Is there a way to force the dependency to fail in that case?

Or should get_current_user raise an exception if no user could be found?

[frank shoal]

Use a different dependency called require_user which raises a HTTPException

i.e. ```py
def require_user(current_user: User | None = Depends(get_current_user)):
if current_user is None:
raise HTTPException(401)
return current_user

[frank shoal]

@iron magnet ?

[iron magnet]

@frank shoal Ah, that’s a great idea!

[hard whale]

Probably not quite python question but... I have a big table from sqlite bd on a home page and i want to add sorting and filtering. What is the best way to implement it provided I have no JS experience?

I use fastapi to interact with the db and a little jQuery

[frank shoal]

I suggest using datatables.

[hard whale]

Tell me more please

[frank shoal]

https://datatables.net/

[hard whale]

I used Semantic UI to add tables to the page, but there is no pre-added sorting

[frank shoal]

If you have a lot of data, you could use ajax and the pip library sqlalchemy-datatables to handle it.

!pip sqlalchemy-datatables

[lavish prism]

sqlalchemy-datatables v2.0.1

SQLAlchemy integration of jQuery DataTables

[hard whale]

Hm ok, so its not in vanilla sqlalchemy?

[frank shoal]

It's not a plugin, just a layer on top.

[hard whale]

I.e. I have full sqlalchemy installed

[frank shoal]

You just give it a list of columns, your url search params, and your initial database query, and it handles the rest.

[lilac grotto]

When I have a input field for example and when the field get changed I want to make a popup to save the Changes. How could I detect the change of the input field?

[frank shoal]

Oh, you want a live view of the data that you can change?

like a spreadsheet?

[lilac grotto]

Yea

If any data in given fields gets changed then a action should be performed

[whole drift]

for images <img> use get_attirbute("src")
this will give you the link, for a href use "href"

[frank shoal]

try jQuery.sheet?

https://spreadsheets.github.io/WickedGrid/

[lilac grotto]

Is there maybe any way to do it with Flask?

You can take Discord Roles as a example. If any Text/Permissions gets changed you get a prompt to save it

Thats what I need

[abstract birch]

that would probably be a javascript thing and not python

[frank shoal]

Well it wouldn't be too hard to make a CRUD endpoint in flask.

It would just be detecting when a input is changed and setting a flag.

It's a bit simpler in a framework like vue

[abstract birch]

I got a small question, I got a db on mongo and using flask.
Do you guys know anyway I can show the database on the website in interactive way? so the users can filter through stuff, search and export the results ?

[frank shoal]

datatables!

https://datatables.net

[abstract birch]

hmm looks pretty neat but I can't see export feature

[lilac grotto]

Would it just loop a GET request or how would that work

[frank shoal]

https://datatables.net/reference/button/csv

[abstract birch]

thanks i'll dig in

[frank shoal]

single requests containing all the data via a PUT request. or some of the data with a PATCH request

put is replace. patch is edit

[inland oak]

two options
a) Building frontend on your own (Full customization to any desires, longer development)
b) using some already prebuilt tool (Nearly instant development, limitations in features which are nearly impossible to add)

[lilac grotto]

But is that even possible with a simple <input>?

[abstract birch]

datatables seems to have everything I need

[frank shoal]

You would need to use the onchange event and mark a variable named something like dirty

[lilac grotto]

I tried with the onchange event and jinja context proccessor but it called the onchange function already when the page was loaded

[winter sinew]

Hello ladies and gentlemen! Got a quick question regarding managing classes. I finally worked out a working webshop with a "Item" class. The "Item" class has many functions on it and is referenced in other classes to make the cart and checkout process running. Now i want to specify the products by creating new classes like "Shoe" or "Tshirt" which each has own attributes additional to the "Item" class attributes. What are my options to do that or what is recommended to do? I came around Abstract Base Model but i can not reference to abstract models. I read about PolymorphicModel, but is it really the way to go?

[frank shoal]

with sqlalchemy or django?

[abstract birch]

you ever tried to work with it on flask?

The table isn't loading at all, tried with hard coded data and its good

[frank shoal]

use serverSide: true, ajax: "/some-url"

You do need a <table> tag somewhere too

[abstract birch]

yea I got <table>

never worked with ajax 🥲

[frank shoal]

ajax is just a old version of fetch

make an endpoint in flask, and you should be fine.

[abstract birch]

like it should be a GET that returns the array ?

[frank shoal]

<table id="table">
    <thead>
    <tr>
        <th>Field 1</th>
        <th>Field 2</th>
        <th>Field 3</th>
    </tr>
    </thead>
</table>

<script>
    $(document).ready(function() {
        $("#table").DataTable({
            processing: true,
            serverSide: true,
            ajax: "{{ url_for('datatable_ajax') }}",
        });
    });
</script>

[wicked comet]

Guys have you heared about pyscript ??

[frank shoal]

from datatables import ColumnDT, DataTables
from flask import Flask, request

from .models import db, Table

app = Flask(__name__)

@app.route("/datatable_ajax.json")
def datatable_ajax():

        ColumnDT(Table.field_1),
        ColumnDT(Table.field_2),
        ColumnDT(Table.field_3),
    ]

    query = db.session.query().select_from(Table)
    params = request.args.to_dict()
    row_table = DataTables(params, query, columns)

    return jsonify(row_table.output_result())

libraries: flask, sqlalchemy, sqlalchemy-datatables

[abstract birch]

the Table and db is sqlite?

[frank shoal]

it's your sqlalchemy models

someone can help with my problem? https://stackoverflow.com/questions/72211918/the-view-budget-views-budget-didnt-return-an-httpresponse-object-it-returned-n

You probably returned None there

[short flax]

Hmm but where is the none? Everything on b_form is copy/paste from a_form that is working

[serene prawn]

You don't return anything explicitly at the end

Oh, right, sorry 😅

Didn't see the render call

[short flax]

the render call was on else: statement

and i was getting that error

i removed the else and reverted the indentation on render and i dont get error nor income value is adding

a_form still working

no idea what is wrong :/

[serene prawn]

I'm not sure what's wrong there too, all i can suggest is debug it and see what you actually return from the function 🤔

[native tide]

Won't the post request get resent to the same view if u use redirect

@short flax

Won't it become infinite post loop

🤔

[short flax]

Well maybe.. but still b_form somehow is not valid

[native tide]

if u have primary keys

then it will throw an error while saving

[native tide]

can u send b_form model?

or form validator

[short flax]

`class BudgetData(models.Model):
SPOZYWCZE = "Spożywcze"

guys, i cant understand this: if i create templates in django, am i doing some kind of frontend development? so if i create just an api in django, can i then make the frontend in, for example, react and take the information from the django api i made? or am i confusing a lot of concepts?

[dense slate]

Yes you can do font-end dev and just connect to your django backend.

Templates are for FE dev for those that don't want a full FE framework like React/Vue

You'll look into Django REST or Graphene / GraphQL for that.

[dusk sonnet]

Hey, im planning to build a Chat Room Web App using Django and for the past day or two iv just been researching and watching videos on it because its a whole new realm for me. But one thing i havent been able to understand is how Redis is used? so to my understanding Redis makes queries to the database way faster because everything is stored in "memory". And you cant use "inMemory" for your CHANNEL_LAYERS unless its for testing purposes, which is to my understanding why Redis needs to be used for production and deployment. However i dont actually know how the process works. Like once you write channel_redis.core.RedisChannelLayer in settings.py to like initiate it, is that it? or do you have to start configuring and managing your code to suit it or something? I havent found any material that has helped me understand this part of it. Mostly i just see people use 1 line and thats it or something.

if anyone knows any good material that helps understand Redis i would really appreciate it.

[dense slate]

I haven't used it much but my understanding is that Redis is a cache, so I would think that you wouldn't want that for a real-time implementation.

It would be better suited for something where you don't want to have to hit the server a lot, so maybe some queries that won't change often.

[dusk sonnet]

oh sorry i meant Asynchronously im an idiot i thought Real Time and Asynchronous are the same but they not

[inland oak]

redis is a simple key-value database. imagine it as a dictionary that can stores as keys and values only strings, and all of them are stored in RAM ;b

plus the record has a time to expire property (which can be inifinity), once it is expired, it becomes not valid

so you can tinker with how long is valid the record there

[dusk sonnet]

tinker?

[inland oak]

you can set something like redis.set("abc", "123", TimeDelta(minutes=5))

your record 123 will be valid for 5 minutes

after that something happens

[dusk sonnet]

ohh i see

[inland oak]

redis.get("abc") to get the value of 123

[dusk sonnet]

so sort of like Snapchatish

for example sending a message and then you can set a time until that message is removed?

[dusk sonnet]

oh right

[inland oak]

anyway. The point of Redis is that it is just the same dictionary, but its data is shared across instances of your application

accross multiple backend instances (we usually ran several django app instances in parallel to handle traffic of multiple users at once)

or even across several different backend apps

but it is basically still same dictionary with a bit different functionality, which just ensures having dictionary with shared memory across app instances

[dusk sonnet]

right but do i need to specifically mention it to store things in it? so for example (exclude django channels) if i wanted to save something to the database i would usually use the .save() command, do i need to do these types of things when using redis?

[inland oak]

If u a pervert, you could reinvent the wheel and make the same with multithreading stuff btw 😉 but it will be complex and not needed of course

[inland oak]

redis default library just gives redis_conn.set and redis_conn.get, that's it

at maximum it can give you saving and getting objects in bulks in addition

the rest is something invented on top of it

[dusk sonnet]

oh so when you declare it using something like this is that all that needs to be done?

CHANNEL_LAYERS = {
  "default" : {
    "BACKEND": "channels_redis.core.RedisChannelLayer",
    "CONFIG": # etc
  }
}

[inland oak]

sigh. details of the channels implementation is details of the channel implementation. If it uses it that way, ok.

those are already details under the hood of the django channels library

any library can use under the hood any other library/stuff

the difference is only channel library requiring to have raised infrastructure object of redis

same when Django requires instance of postgresql if u wish to work with it (it utilizes Sqlite3 as default alternative though)

[dusk sonnet]

Ah right. Thank you this was very helpful and informative, i appreciate it.

[tiny ermine]

Hi guys, I have a website project powered by Flask. This website presents a visualisation of some common sorting algorithms. The sorting algorithms themselves are written in python, but the implementation of getting the data is written in Javascript atm. Is this a valid approach? Because, when I click on a "sort" button, Javascript sends many requests to Flask using requestAnimationFrame

[midnight tundra]

docker-compose

[inland oak]

it does not sound like valid approach. Too many requests

as a fix, consider sending frames in bulk, all at once or just more frames per request

or implementing sorting at client side in js (the most performance wise approach to this problem)

[tiny ermine]

ahhh so do the sorting algorithms in javasccript itself right

[inland oak]

yeah. Preferably consider using frontend framework like Vue.js

it will make your job way way easier

[tiny ermine]

wdym

why

[inland oak]

because Vue.js will bind your data from its Model to be directly shown as in its View, in a MVVM scheme as far as I remember
You will be able just to have the data changed in Vue (sorting it when doing smth), and it will automatically rerender to user screen

everything at clientside, without any requests

this is the easiest approach to Client side javascript

[tiny ermine]

oh really?

so i don't have to use any python?

or can i still use flask

cuz i really like the templating

[inland oak]

Vue.js has 10 times more powerful templating

giving you also access to stuff like SCSS

[tiny ermine]

so don't even use flask?

[inland oak]

technically u don't need Flask at all in this task

pure frontend job

[frank shoal]

Using vue.js, I miss jinja's pipe syntax

[inland oak]

attempt to write js in jinja, and the piping problem will be seen like a minor 😆

[tiny ermine]

ok 1 more thing

i want to make like a debugger sort of screen

so basically the data of the sorting algorithm is passed into a linked list

which can display the variable names of the current "step" or "pass" of the algorithm in a table

or some sort of display type

[inland oak]

xD, i did literally stuff like that once. I made debug shown from Ansible running playbooks 🙂

[tiny ermine]

and the user can go forwards and backwards

to see how the code is working

[tiny ermine]

and this will also happen alongside the visualisation

so u saying all this is still a frontend task

[inland oak]

it sounds to me like a still just frontend

[tiny ermine]

how hard is it to pickup vue.js

[inland oak]

I got a hang and started doing my projects within a matter of 1 and half of a week in vue.js

with learning frontend literally from zero

html, css, js, i knew nothing

[tiny ermine]

are there any good tutorials that get u up to speed

[inland oak]

at the website is written that you can learn vue.js from 2 hours to within a week. Vue.js is easiest to learn out of frontend frameworks

[inland oak]

I got started from

Then went through

then made a stop at

plus went through one less worthy to mention book
and then started learning vue.js docs

[tiny ermine]

how does vue do this

[inland oak]

it is magic under its hood

a matter of using Patterns of Programming and having Clean Architecture in itself

just cool designed code and the data flow of data

which becomes a bit complicated if we remember that it works that well while being in browser and its ecosystem, DOM and browser APIs

amazing framework.

basically it is using as far as I know virtual DOM, which is reviewed to the user

[frank shoal]

How vue (and most other frontends) works: When state changes, it destroys the node and rerenders it instead of editing it inplace like you would do with jQuery and DOM traversal.

[inland oak]

and probably uses all those javascript listening stuff in order to get feedback back

[inland oak]

in React people can control rerendering at a lower level apperently

more complicated framework to use

[frank shoal]

vue has v-once

https://vuejs.org/api/built-in-directives.html#v-once

[inland oak]

curious

what if in higher component happens the change?

and we froze with v-once child components of this component

[tiny ermine]

hmm ok

[frank shoal]

If you need to manually rerender a node for whatever reason, (you're probably doing wrong reactivity, computed, watcher, key with v-for) you can use $forceUpdate()

if the element is in the child component, you can use emits to update the parent. There's also inject and provide for similar, global functionality

https://vuejs.org/guide/components/provide-inject.html

[tiny ermine]

any good guides to use vue.js quickly

[frank shoal]

emits is essentially making your own events, like @change="onChange"

I enjoy this channel. https://www.youtube.com/c/ProgramWithErik

Ben Awad for general javascript and react.js

There's also this to play around. https://sfc.vuejs.org/

[tiny ermine]

okay thanks!

[tiny ermine]

btw are there some youtube tutorials on vue.js?

[frank shoal]

see the channel I posted.

Here's a whole playlist
https://www.youtube.com/watch?v=YrxBCBibVo0&list=PL4cUxeGkcC9hYYGbV60Vq3IXYNfDk8At1

[tiny ermine]

thank you so much

[hollow dragon]

been working on my first Flask project for a while, i love Flask, so good.

[frank shoal]

That's a good looking frontend.

[hollow dragon]

thank you, I was learning / doing frontend before switched to python / flask

but I'd say it's 50% completed

[frank shoal]

Good luck on your way to full-stack

maybe soon, you can switch to fastapi as a rest backend for your react or vue app

[hollow dragon]

sure, I'm just working on Flask and building this project for my upcoming internship (company uses flask)

[stoic lark]

what about pyscript ? 🙂

[hollow dragon]

wdym?

[inland oak]

is it a weird attempt to make frontend python scripting?

not valid for real world production

[hollow dragon]

https://tenor.com/view/monkey-bruh-weak-sick-gif-16818912

[stoic lark]

still we have to know good javascriot right

:S

[hollow dragon]

i hate javascript

[inland oak]

There is a choice in javascript, javascript and javascript for frontend
Have I mentioned javascript? xD

[hollow dragon]

i used vanilla JS for like 9 months without a framework, it was a pain

[stoic lark]

😄 😄

[inland oak]

well technically there is typescript in addition. But you know, it is still javascript under the hood.

[hollow dragon]

for this, or for flask / api projects, apps you don't really need js. but you could easily integrate js / react or any frontend framework into it

i might do it later

[inland oak]

yes it is. Frontend framework javascript is different and much better

[hollow dragon]

but i feel like that would be an overkill for an internship

also i want to deploy this to heroku with docker lmao

[stoic lark]

flask

is more little projects right ?

[hollow dragon]

yeah

microframework

but u can use blueprints for larger apps

[stoic lark]

i use django

used*

there is lots different techs this development things going more complex always..

[hollow dragon]

yeah I'd like to learn django down the road long-term

[covert yew]

any good frontend tutorial?, I have my flask project and I want to stop using bootstrap and write my own styling.

[serene matrix]

Does it make sense to automatically create a new table for every use when they sign up? To keep record about that particular users activities

[covert yew]

wdym?

table for every user?

[proper knoll]

Hello there.
I'm working at a small company that already have a fully implemented java backend, but wants to start migrating to python, starting with some more costly endpoints.
Is there a more a more recommended framework ? A guy in another channel recommended me FastAPI, since my objective is exactly to go fast

But is it recommended for big and scalable servers ?

[frank shoal]

I've found fastapi to be similar to spring in some aspects.

[serene matrix]

Yes. To store stuff like "people interacted with", notifications,etc

Just user specific stuff

[hollow dragon]

if im planning to interview for an internship, should I just improve, tweak this app or try to build as many as possible?

[serene matrix]

Wouldn't it make sense since pulling that data from a per user based table would be faster than using one general table?

[next widget]

anyone here familiar with selenium, also django, running locally?

[serene matrix]

Django here but not selenium

[next widget]

well my app is trying to execute a chromium.exe file, but I get an error that it has the wrong permissions. I'm able to run it in heroku, and locally elsewhere, but not here locally through the procfile

I'm sure its a windows 10 permissions thing, chmod 777 apparently is not a thing here

I tried cacls myfile.txt /g everyone:f

on the exe, but I get the same error

[thorny lake]

Selenium but not django

[next widget]

well here is the error I'm seeing "selenium.common.exceptions.WebDriverException: Message: 'Home-Finance-App' executable may have wrong permissions. Please see https://chromedriver.chromium.org/home"

[short flax]

someone can help me with my problem in django? https://stackoverflow.com/questions/72211918/the-view-budget-views-budget-didnt-return-an-httpresponse-object-it-returned-n

[thorny lake]

most likely wrong .exe path to your chromedriver

[next widget]

that makes sense to me. I've added the full path to the .env file to the exe

(I am new to django)

[thorny lake]

If the .exe is for the chromedriver it just means you have to have it on your local machine - how are you calling it?

[next widget]

chrome_options.binary_location = os.environ.get("GOOGLE_CHROME_BIN")
chrome_options.add_argument("--headless")
chrome_options.add_argument("--disable-dev-shm-usage")
chrome_options.add_argument("--no-sandbox")
driver = webdriver.Chrome(executable_path = os.environ.get("CHROMEDRIVER_PATH"), chrome_options = chrome_options) 

my workaround is to comment that code out and to use this code when I run locally and it works fine.

options.add_argument('--headless')
options.add_argument('--disable-gpu')  # Last I checked this was necessary.
driver = webdriver.Chrome(chrome_options=options)```

though the latter doesnt work when I push to heroku

Actually I havnt tried, but I'm sure it wouldnt.

[thorny lake]

and in your .env for the app the driver is stored in "GOOGLE_CHROME_BIN", correct?

[next widget]

yeah right

[thorny lake]

Scratch that, it's actually referencing where it is on your local machine - what is the "CHROMEDRIVER_PATH"?

[next widget]

GOOGLE_CHROME_BIN = "C:\Users\aa\Home-Finance-App"```

I set both to the same 🤷‍♂️

I might be spending too much time on it already... the work around isnt horrible for me.

[thorny lake]

Lol, ok well is that where it is ?

[next widget]

yes, ha I did put the chromium.exe file where the enviornment variable is pointing to, above

and changed its permission using some windows ca function

[dense slate]

@inland oak I updated my production server and I can still access the django admin but I'm getting an nginx gateway error when accessing the site. There were no nginx changes. Anything stick out as a possible reason I'm getting the gateway error?

[silver horizon]

how will you make the models for that/

?

Create a REST API for cars. It should contain accounts, CarBrand, UserCar, and CarModels. Each user has to be extended by default Django abstract class and should contain a few more columns (for your choice). Each car object contains relations to the user and CarBrand. Each CarModel contains relation to CarBrand. It is all your decision how you will distribute models to different apps. Please make the API URLs with filters (custom typed). All models should be with soft delete.

Models fields:
CarBrand [name, created_at, deleted_at]
CarModel [car_brand, name, created_at, update_at]
UserCar [user, car_brand, car_model, first_reg, odometer, created_at, deleted_at]

Auth:
Please extend the default Django user class and add some custom fields. Create login, and register functionality. User default Django permission classes.

[thorny lake]

It doesn't look like it's referencing the ChromeDriver itself though, try extending the path with the actual chromedriver variable

[inland oak]

there can be multiple reasons
Do u use cloudflare? They restrict traffic to 80 443 ports
Same questions goes if you use AWS for example

[dense slate]

Using DO

But nginx was working fine before, no changes to it.

[inland oak]

then we can ask questions in how you deploy your stuff, docker-compose, kubernetes or whatever system

[dense slate]

pulling directly from github

[inland oak]

manually?

[dense slate]

Yea

[inland oak]

that's already a reason in itself.

[next widget]

ok I'm not sure what that means, when I have run selenium in the past, I just download the exe, put it in the scripts directory, and it runs fine. There is no other 'chromedriver' directory, as far as I'm aware

[inland oak]

it already means that you can't rely on that you did not change nginx / code of deployment

because your deployment is not automated / not a code

[dense slate]

But nginx is only on the prod server.

[inland oak]

u a supposed to have staging environment to test your deployment

even it is homelab, we still having staging / testing env

[inland oak]

that's another problem, that nginx is present only on the prod.

your staging environment to test your stuff should be as close and similar to prod as possible

i see no reason why you have nginx only in prod

[dense slate]

You're suggesting to run it also locally?

[inland oak]

i am suggesting to raise temporal infrastructure in DO that exactly matches prod one, but just uses cheaper resources

if you do it for work

[dense slate]

Yea I'm actually going to set that up now, but I'm going to have the same problem in the staging server.

[inland oak]

that's exactly the point

to discover it in staging before making deployment to prod

[inland oak]

if you made mistake and something like that appeared in prod, you are supposed to have a way to rollback yourself to previous prod version, and then calmly debugging in staging/dev env

[dense slate]

Yea, I'm not disagreeing with that. 😄

[thorny lake]

Ok this could be a django/windows thing, I've never ran selenium that way - strictly python/mac, most of the current errors since the update have to do with calling the executable path which has since been replaced with the Service() object, but doesn't seem to be the error you're encountering right now - if chromedriver is somehow enabled within the heroku app through the application source path solely that could also point to Heroku implementation taking care of the issue you're seeing locally. Have you ran it on this machine before?

[next widget]

no I have not run into issues (like this) with selenium before. I think youre right its a django/windows thing. I know when I put this on heroku, there were two heroku specific github build packs that had to be added. But like I said, in my experience running locally, I've never had to get more than just the exe.

anyway I have a workaround, its messy and annoying lol, but it works for what I'm doing just fine.

[thorny lake]

If it works and there's no dire need to have it be ran the exact same way, Heroku has it's own way of doing things sometimes - but also be careful with it, they had a security issue running GitHub pipelines a few weeks ago.

Just curious, when you launch the app locally are you running it in a virtual environment?

[next widget]

thats interesting, I didn't know that. My plan right now is using the heroku app only to make already public data more easily accessible to me (for now), so I'm not too worried about that. But it is good to know, thank you.

[next widget]

I am yeah

[thorny lake]

I still don't think GitHub is allowing connection to Heroku via pipelines - I had a couple minimal apps deployed that way that have since been disconnected by GitHub while Heroku has been prompting a force change of passwords - https://github.blog/2022-04-15-security-alert-stolen-oauth-user-tokens/

[next widget]

I guess I don't understand the heroku buildpacks, from the desription on heroku, they are scripts that are run when the app is deployed. is that considered a pipeline?

hi @native tide

[wheat verge]

Is there any documentation to lear about follow notation in django

[thorny lake]

Heroku buildpack is basically a compiler service - different from the pipeline implementation I'm referring to, the buildpack can be a seen as a step in the pipeline towards deployment. When you upload your app to Heroku directly that transfer can be seen as part of the "pipeline process" independent on whether that step is automated or not. If you host your app in a GitHub repository and make updates to the codebase by pushing changes etc. you could set up a pipeline that connects to Heroku, any changes you make to the codebase and push to GitHub will be automatically processed by Heroku to update your application.

[next widget]

oh, I remember the github linked deployment options. This is great, thanks.

[next widget]

for me these 15 steps were a great intro: https://devcenter.heroku.com/articles/getting-started-with-python

oh you asked about django... well that is django on heroku

[hard whale]

Hello guys, I'm using semantic ui to make my page look better but I faced some weird stuff... I have 2 tables and I want them to go one under another when browser window is narrow and they cant fit together. But what i get is they overlap before actually going one under another

<table class="ui black selectable collapsing table">

here is the table class i use

Both tables are in

 <div class="column">

[thorny lake]

That's if they ever work together again, this is a major breach of trust when it comes to security, GitHub has standards to protect their users which was compromised by the Heroku (Salesforce) partnership.

[hard whale]

I want tables to keep their size ie no scaling to browser size

[thorny lake]

This is probably more applicable to #user-interfaces

[hard whale]

And when the window is too narrow one should go under another

Its web page tho

Not sone offline gui

[strange wing]

only offline guis being classified as uis is an interesting take

[hard whale]

🤷‍♂️

[strange wing]

try explicitly stating their height in css

should work

[hard whale]

If u r sure that channel fits better i can move np

[strange wing]

If I've got a button in Django that is chained to both trigger a submit/post request and a JS script, is there any way I can make the JS execute first?
Right now I've got a view that takes a really long time to render, so I want to trigger a loading screen to pop up with a JS script before the next page starts loading.

[hard whale]

I didnt write a single css line of code in this project , i hope there is some way to just use semantic ui classes

[strange wing]

I think the point is that this is a Python server, you can check out the Devcord discord for more specialized help with html/css/js and online ui frameworks

[hard whale]

I'm fine thanks

[strange wing]

Okidoke, I'm not gonna judge you when you realize this is a python server, and this channel is mainly for web hosted python backends rather than UI.
Take it as a friendly server recommendation, not me telling you to go somewhere. They are a lot more general UI than you are going to find in this server.

[hard whale]

I got your point, i'll ask elswhere

[hollow dragon]

im trying to deploy to heroku but this is what i get:

ERROR: Could not find a version that satisfies the requirement dataclasses==0.8
ERROR: No matching distribution found for dataclasses==0.8

why?

[next widget]

do you have a link handy on this? this is interesting to me. Is there an obvious and better alternative to heroku?

[thorny lake]

link to what?

[thorny lake]

If you're referring to the breach all you have to do is google "github heroku security breach" and it comes up. I'm surprised it's not being talked about more, although it seemed to affect organizational accounts more - (including npm).

The more comparable alternatives in terms of popularity and use-case to Heroku App integration would be AWS services, although I will say there's a higher learning curve dependent on chosen deployment option when it comes to networking and devops. Heroku is a pretty decent service as it's simplified some of the processes you'd have to configure manually via AWS, so it's a good option for production minimal applications. And there's always the perspective of looking at the glass half full, in this case, Heroku tightening up security on their end.. Heroku of which hadn't even recognized the breach until Github informed them. - https://thestack.technology/github-hacked-npm-data-downloaded-in-an-evolving-supply-chain-attack/
There's also GitHub pages which can act as a pipeline service similar to Heroku (i.e. pushing changes to the codebase configures the deployment app automatically) and is relatively easy to set up. - https://pages.github.com

[hollow dragon]

yeah, i officialy hate heroku

[ionic raft]

By the way, bruh, Digital Ocean is working out VERY well. Really enjoying the alpha deployment with pipeline to git for changes. Their offering is very solid experience.

[ionic raft]

Interesting. I tried to use Heroku for my Flask deployment. That went...ok.
Then I tried to use Heroku to test out a cron redis server for some Django Async. Went poorly.
Gotta say, Heroku gets left in the dust next to my Digital Ocean experience.

[ionic raft]

I got an email about that breach. Was that the public repo brute force attack? Or something else?

[inland oak]

👍

[native tide]

heyy I need some guide for starting programming... any professional who can help me.. pleasee dm me it's important😭

[hollow dragon]

holy shit

i just deployed my first docker app on heroku

spent like 10 hours straight bugfixing but now it works

cant believe itttttt

[eternal blade]

I'm serializing models and sending it through the websocket, for the serialization I'm using django-rest-framework
the models also contain images but when the images are being serialized the absolute url of the image isnt being shown (only the relative url of the image)
looks like to get the absolute url of the image i need to pass in the request object into the serializer context but I dont have access to a request object (since im using consumers)
one person suggested that to override to_representation and return the image url there but that doesnt seem like a very good way since the host of the backend can change which will lead to a lot of bugs

[hard whale]

Can anyone recommend some easy plot framework to draw plots in real-time from sqlite table

I use FastAPI + SQLite + website with semantic ui elements

I would like to implement a visualisation of 5 variables changing their value overtime

[thorny lake]

private repo attack via compromised Heroku Oauth tokens.

[hollow dragon]

is there anyone i can ask for Flask help?

[eternal blade]

maybe i can use the socket library?
im not sure how exactly though

[hollow dragon]

I have a flask app and I want to give different results for different users.

How is this possible?

I use flask-login ofc

[dusk sonnet]

im gonna ask a very stupid question here so just bare with me. I wanna build a Chat App with Django Channels + Redis right. And iv been watching alot of tutorials in the past few days and reading the docs however im so confused as to when i should stop watching the videos that makes a chat app and start implementing everything myself. Because right now all iv done is pretty much just copy paste from the Django Channels docs...and i, myself have not implemented anything. So should i just stop watching these videos and start thinking what i want in my app and start researching specific things i want instead of watching someone make the whole project? idek why im asking this lol

[native tide]

wat the heil do u want imo

Ultimately, what is considered enough hand-holding will fall down to you as the learner. You might find that stopping watching now, and working things out yourself is helpful to you learning, or you might find that building the entire project while someone is holding your hand is more helpful

Over time, you'll find that you've developed skills, and picked up a few techniques that help you start working on your own

[dusk sonnet]

ye i think i might just start myself and see how it goes because ultimately if i keep on watching the vids, in the end i will just get all the answers when i havent even started yet and then there's no point to doing the project if iv literally seen how you implement it.

[native tide]

I wouldn't necessarily say there is no point

It can help you pick up skills and tools that are used in the video, you've just gotta find what works for you

[dusk sonnet]

ye true

[unreal snow]

what kind of code can i use to read the data in my database and show it in this page (m using flask)

[hollow dragon]

anyone?

[dusk sonnet]

You use Jinja syntax in your template. So in your apps.py i think it is, put whatever data from the database you want in a variable and then pass that variable to your template. Then in your template use Jinja syntax to loop over that data and grab the things you need.

So for example, in apps.py if i select all the fields from the database and pass it to a variable called data, and then do something like data=data to pass that variable to ur template. Then in your template, you loop over data by doing something like:

{% for d in data %}
   {{ d.fieldname }} 
{% endfor %}

[hollow dragon]

damn i love using https://sqlitebrowser.org/ with my databases

[dusk sonnet]

ye its so good

[hollow dragon]

Also real time updating is so useful

Making working with databases an easy job

[unreal snow]

i already use this but still it didn't show the data in the home page

[dusk sonnet]

show me your code

[dusk sonnet]

ur using User instead of user

change all of them to user all lowercase letters because thats the variable looping through the User variable that has all the database data

[unreal snow]

even the class is named User ?

[dusk sonnet]

no no

so in ur template ur using for example {{ User.fullName }}, change that to {{ user.fullName }}

remove that capital letter from all of them that are in the <td> tags

[unreal snow]

{% for user in User %} i should chage that too ?

change *

[dense cedar]

no

just change it inside

td

e.g:
for i in fruitsList:
print(i)

it will print that fruitsList array element which is on that index

[whole sierra]

anyone used htmx?

[unreal snow]

should i change something here ?

[dusk sonnet]

all u need to do is just change User to user in every <td>

[dense cedar]

Yes. You should use dictionary

[dense cedar]

it's django

right?

[unreal snow]

nah it's flask

[dusk sonnet]

its flask

[dense cedar]

okay ignore dictionary part

[unreal snow]

yet , nothing changed

[dusk sonnet]

show the code

[unreal snow]

the html ?

[dusk sonnet]

ye

[dusk sonnet]

can you show the code where you pass the User variable to this template

[dusk sonnet]

this is for signup.html

[dusk sonnet]

idk what current_user is but the variable u passed is called user not User

[dense cedar]

user = current_user?

can he iterate?

[dusk sonnet]

and ur looping through User which doesnt exist

[dense cedar]

the current user?

which is a single object?

[dusk sonnet]

idek what current_user is

[dense cedar]

request.user

[dusk sonnet]

but this is flask

[dense cedar]

it's similar as request.user

I meant

[dusk sonnet]

oh right

[dusk sonnet]

dont you want to pass the data in your database?

[unreal snow]

the probleme that i wanna show the data

[dusk sonnet]

in your home function create a variable call it like data or something and in that variable select all the fields from the database you want

right now what ur doing doesnt make sense. u are looping through current_user which from what it looks like just gets the current user thats logged in

but how does current_user have the data you want form the database

[dense cedar]

yes

It's not an array like this :
Food = [

// FRUITS LIST
{
"orange":"good",
"Banana":"tasty",
"Pineapple":"nice"
},

// Vegetables List
{
"Carrot":"red",
"Raddish":"super"
}
]

It's only single object like this:

{
"orange":"tasty",
"pineapple":"fresh",
"apple":"red"
}

[zealous oar]

Hey, I have a model like this

class Task(models.Model):
    name = models.CharField(max_length=120)
    hours = models.SmallIntegerField()
    mins = models.SmallIntegerField()
    created_at = models.DateTimeField(db_index=True, default=timezone.now)

I wanna make a filter that returns every object created in the current year and month
I tried something like that, but this is not what I want

Task.objects.filter(created_at__date=timezone.now())

any thoughts?

[whole sierra]

Task.objects.filter(created_at__range=["2011-01-01", "2011-01-31"])

Task.objects.filter(created_at__year='2011', created_at__year='2011')

[zealous oar]

Are you sure about this?

[whole sierra]

pretty sure it should work, try it out

[zealous oar]

raise FieldError(django.core.exceptions.FieldError: Cannot resolve keyword 'created_atyear' into field. Choices are: created_at, hours, id, mins, name)

[dense cedar]

created_at__year

[whole sierra]

show me your new code

ah my bad

the format didnt come out

[dense cedar]

it was ur typo

[whole sierra]

i assumed you'd realise'

created_at__year

change it to this^

discord wouldnt let me add another _

[dense cedar]

can I ask u a q?

[whole sierra]

yh

[dense cedar]

Ive been asked what is best cbv or fbv

what should I answer?

[whole sierra]

depends what you want to do

[dense cedar]

ok

[whole sierra]

what are you creating your framework for?

maybe give this a read

https://medium.com/@ksarthak4ever/django-class-based-views-vs-function-based-view-e74b47b2e41b#:~:text=Django has two types of,code over and over again.

[dense cedar]

Thanks

[whole sierra]

its the same a oop

@zealous oar did it work?

[zealous oar]

Works fine, appreciate ur help, thank you.

[digital hinge]

Also interested in your approach, I want to display my database and filter the results with a search box

[zealous oar]

If you have a time, I need your help with another issue, I wanna return the highest month in which objects were created,
let's say we created three objects,
object_1 in month 2
object_2 in month 5
object_3 in month 5

so we have to return 5 with is the highest month
I did something like this and it works fine

mx, highest_month, dic = 0, 0, defaultdict(lambda: 0)
for object in Task.objects.all():
    month = object.created_at.month
    dic[month] += 1
    if dic[month] > mx:
        mx = dic[month]
        highest_month = month    

but my question is how can I optimize it using something like the aggregate method?

[whole sierra]

sorted_dates = sorted(chain(query var1, query var2, query var3), key=attrgetter('datetime')) @zealous oar

[zealous oar]

can you explain your thought?
I wanna return the highest month where objects created, not the biggest

[whole sierra]

what do you mean

[zealous oar]

Let's say the user created 2 objects from Task model in May and 5 objects in January

Then January is the highest month

[whole sierra]

you mean you need it sorted in reverse order?

that will sort it in ascending order

sorted_dates = sorted(chain(query var1, query var2, query var3), key=attrgetter('datetime'))

this will sort from January to December @zealous oar

[zealous oar]

yeah, thank you

[winter sinew]

Hello ladies and gentlemen! Got a quick question regarding managing classes. I finally worked out a working webshop with a Item class. The Item class has many functions on it and is referenced in other classes to make the cart and checkout process running. Now i want to specify the products by creating new classes like "Shoe" or "Tshirt" which each has own attributes additional to the "Item" class attributes. What are my options to do that or what is recommended to do? I came around Abstract Base Model but i can not reference to abstract models. I read about PolymorphicModel, but is it really the way to go?

[dusk sonnet]

Hey theres something i have been wondering about django channels and its not really something i can specifically search about. So channels uses consumers.py which is their version of views.py. My question is that when i create an authentication system where user can register, login and logout, do i have to do this in consumers.py with new syntax that come with channels module since im using async and await or can i just do it normally in views.py?

[fickle basin]

Hello, any one using Django with vuejs !

[inland oak]

xD i did. I have already made project with this combo

read the https://pythondiscord.com/pages/resources/guides/asking-good-questions/ though

don't ask to ask, just ask (google it)

[fickle basin]

@inland oak I did google that found, axios, Django rest react , Django vuejs nothing really straight forward but thx 🙏

[indigo kettle]

I think they were just saying that you don't need to preface your question with an intro. Not that you should google it instead.

[native tide]

Hey, why would someone use django REST or Flask, instead of FastAPI + SQLalchemy?

[indigo kettle]

I haven't used flask or fastapi very much. But the reason I wouldn't want to change from django is because there are some features it has that I really like and don't know how they are in those other frameworks. Like django's orm, migrations, drf

[frank shoal]

flask uses sqlalchemy and alembic for orm and migrations

I have no idea what drf is

drf: django rest framework?

fastapi does that by default. Return a dict in your view, and it will output as json

there's also pydantic which helps with the schema

[inland oak]

no no, i mean literally, google "dont ask to ask, just ask"

[inland oak]

and yeah, Django as Django Rest Framework and Vue.js with Axios for requests library, that's how usually stuff happens

[inland oak]

Django is really nice of course but it has one major minus which other devs could say...

...it forces u to marry the framework (with all of its out of the box solutions)

to accept its architecture and build on top of it

polluting your business layer of code logic

that could be seen as a literally a nightmare

and once u marry the framework, changing it to some other framework for the project becomes nearly impossible task

So... against of Clean Architecture stuff

we can also say that it also introduces the problem of upgrading the project

imagine upgrading the project to newer version, when Django stuff goes across entire your project in each code section?

once u upgrade django... since the dependency is not really in one place localized behind proper code layer separation, it becomes a bit of a nightmare when everything breaks everywhere

I did not check at the depth FastAPI, I wonder if it is different in this regard, it should be in theory since it said to be microframework like Flask

Flask is certainly not forcing anything.

for its downsides, Django gives in exchange blazingly fast development speed, and quite high familiarity of other Django devs with structure of the project. It is always essentially remains the same everywhere, regadless of the project

[native tide]

I have a Jinja template:

{% extends "boards/board.html" %}
{% import "macros.html" as macros %}
{% block title %}Threads • {{ super() }}{% endblock %}
{% block main %}
{% for thread in board.threads %}
{{ macros.post(thread, "article", url_for(".thread", slug=board.slug, token=thread.token)) }}
{% endfor %}
{% endblock %}

When I try to render it, I get jinja2.exceptions.UndefinedError: 'thread' is undefined. It looks like the thread variable defined in the for loop isn't accessible in the macro call. How can I pass thread to the macro?

[native tide]

Never mind it was a problem with the macro

[visual bear]

So im trying to have this collapsible information be auto un-collapsed when a link is pressed

<details>
  <summary>Click to show summary one</summary>

## Title One
...

## Title Two
...

</details>

This issue is that if someone was to click a link to my GitHub repo with a link in the following format:

1. github.com/Username/Repo#title-one
2. github.com/Username/Repo#title-two

The link would take them to the page but the section would still be collapsed, and it would not take them to the proper section/header. Is there a way so that when someone clicks the link it's automatically un-collapsed so they can see the information in the header instead of having to manually un-collapse it first?

Please ping when responding if you have the answer, thx

[wind lotus]

What's the relationship between a post and a comment? I know a post can have many comments, but can a comment have many posts? Should I use a foreign key?

[indigo kettle]

I understand they have an orm and migrations, but django's are quite good

[dusk sonnet]

hey, Im tryna use datbase queries with Django Channels however im not getting it right. Iv looked up that i need to use database_sync_to_sync but i cant find much examples online of how to use it properly. The only way i get it to work without error is something like the following code however all it prints out is <coroutine object SynctoAsync...>

    async def connect(self):
        self.room_name = self.scope['url_route']['kwargs']['room_name']
        self.user = await database_sync_to_async(self.get_users)()
        print(self.user)

        self.room_group_name = 'chat_%s' % self.room_name

        await self.channel_layer.group_add(
            self.room_group_name,
            self.channel_name
        )
        await self.accept()

    @database_sync_to_async
    def get_users(self):
        return User.objects.all()

[serene prawn]

You already decorated your function with database_sync_to_async, no need to wrap it second time in your connect function

[dusk sonnet]

ye but if i do this i get django.core.exceptions.SynchronousOnlyOperation: You cannot call this from an async context - use a thread or sync_to_async

  self.user = await self.get_users()

[serene prawn]

That's weird, where is it raised from?

[dusk sonnet]

wdym?

[serene prawn]

The exception

[dusk sonnet]

doing this raises it:

  self.user = await self.get_users()

[serene prawn]

try converting it to list?

return list(User.objects.all())

[dusk sonnet]

oh that workd

why did it work like that and not what i done before?

because i got it from the docs

[serene prawn]

.all() still returns queryset and then tries to do some database opreration in async context

Which is raising synchronous operation error

Example in docs is different

return User.objects.all()[0].name
This is example from the documentation

[dusk sonnet]

ye but isnt it similar i just didnt hard code it

i mean i did try it before exactly as teh docs and it didnt work

[serene prawn]

Now you know

I want to create a model, which lets you select break times for specific weekday. I don't know what is
the best way to link those two models together. I think manytomany field gets messy and confusing
really fast. I want to be able to keep it clean and organized.

Models.py

WEEKDAYS = (
        (1, 'Monday'),
        (2, 'Tuesday'),
        (3, 'Wednesday'),
        (4, 'Thursday'),
        (5, 'Friday'),
        (6, 'Saturday'),
        (7, 'Sunday'),
)
class Breaktime(models.Model):
    weekday = models.IntegerField(choices=WEEKDAYS, unique=False)
    break_starts = models.TimeField()
    break_ends = models.TimeField()

class Breaktimes(models.Model):
    
    weekday = models.IntegerField(choices=WEEKDAYS, unique=True)
    breaktimes = ??

I think many to many relationships are the only choice, but is there a way to filter out the weekdays?

Hello

How to secure a Flask app against CSRF ?

[inland oak]

using non GET request for important actions will increase a bit level of security. (making necessary for hacks to use JS injection at least)
Then we could CSP protection in order to protect us from unauthorized JS files, that will be a first level protection.

for 100% solution, any super important action should be verified by something like getting number from SMS sent to user / email sent to user (preferably email, it looks less bothersome)

plus i heard about CSRF tokens, perhaps they can improve situation a bit too

[nimble berry]

i would agree with @inland oak, make sure you don't accept GET requests for those endpoints, and then i would recommend CSRF tokens as the primary measure after that

[timber jungle]

I kind of understand with the GET and POST end points

This means, on this line <form id="derogationsform" action="{{ url_for("form_area")}}" method="POST">
I should create another function which accepts only POST?
This means what i should have 2 functions ( 1 for GET - rendering the form page, 1 for POST - handling the post request ) ?

[inland oak]

u already have it as endpoint it seems

Form works by submitting as post by default

[timber jungle]

@app.route("/form_area", methods =["GET", "POST"], endpoint="form_area")

The website might not be https

[frank locust]

It is, also it works most of the time, this error happens 10% of the time

[frank shoal]

maybe you go too fast

[frank locust]

Possibly, at what point would I try to slow it down do you think? the initial get or iterating through the orders? Somewhere else?

[frank shoal]

¯_(ツ)_/¯

robots.txt specifies a crawl delay of 600

so just time.sleep(.6) after each request

[frank locust]

ok i'll give that a try

[lime jolt]

Should I use help channels for django questions?

[serene prawn]

It's a web dev channel after all, it's find to ask django questions here

[lime jolt]

I asked it in a help channel a minute ago. In #help-burrito

[native tide]

Hey, how would you call a file that initialize a connection with a db? Like by convention

[lime jolt]

dbconnect, connectiondb, dbconn, dbconnection I guess. Everyone would understand these.

ConnectionBuilder is my preference.

[lime jolt]

Help channel is closed, damn. Let me ask again. Submitting form doesn't do anything. Not even redirecting the url. But if I manually open the html file without server, it redirects.

[frank shoal]

use /createuser instead of createuser/ for the form action

[lime jolt]

didn't work, and normally it should be createuser/

[frank shoal]

Also, I think you're passing xedni to the redirect response

[lime jolt]

method is not called, nevermind the redirects.

[frank shoal]

form action path is relative if it doesn't start with /, meaning if the current path ends with /, it will be appended. If it doesn't, the last path item will be replaced

[frank shoal]

so clicking submit would take you to surveyville/createuser/

that's intended?

[lime jolt]

yes, it should. Btw, I can manually call the function with link.

But submit button does nothing

[frank shoal]

Anything in the console or network inspector?

[lime jolt]

I used jquery to test the button, it can give an alert(""). And directly writing the link activates the function. I can see print("") codes in console.

[frank shoal]

How are you submitting normally? pressing the submit button, or pressing enter on the password field?

Also, you should make the input type="password"

[lime jolt]

pressing button. password can wait 😄

[frank shoal]

But does anything show up in the network inspector when you press the button?

Ctrl+Shift+I, press network

[lime jolt]

looks like nothing happens.

[frank shoal]

Nothing in console either?

[lime jolt]

nope.

[frank shoal]

Did you register an onsubmit event and call preventDefault()

[lime jolt]

if you mean front end stuff, they work. I opened the html file directly and it redirects.

[frank shoal]

Can you share the entire html file?

[lime jolt]

sure

[lavish prism]

Hey @lime jolt!

It looks like you tried to attach file type(s) that we do not allow (.html). We currently allow the following file types: .gif, .jpg, .jpeg, .mov, .mp4, .mpg, .png, .mp3, .wav, .ogg, .webm, .webp, .flac, .m4a, .csv, .json.

Feel free to ask in #community-meta if you think this is a mistake.

[lime jolt]

oppsie

[frank shoal]

!paste

[lavish prism]

Pasting large amounts of code

If your code is too long to fit in a codeblock in discord, you can paste your code here:
https://paste.pythondiscord.com/

After pasting your code, save it by clicking the floppy disk icon in the top right, or by typing ctrl + S. After doing that, the URL should change. Copy the URL and post it here so others can see it.

[frank shoal]

And /js/modal.js?

[lime jolt]

whats wrong with it?

[frank shoal]

idk, you didn't post it.

[lime jolt]

it does this, nothing else

[frank shoal]

Post the modal.js too please

[lime jolt]

https://paste.pythondiscord.com/rinaninoge

[frank shoal]

You disabled the click event in all children in the modal.

[lime jolt]

holy....

i stole the code, that's why 😄

[frank shoal]

just use bootstrap's builtin features to dismiss the modal.

you're not using bootstrap, though....

[lime jolt]

not worth using bootstrap, idk

i created modal 3-4 times but forget how to do it 😄

it works, there are other problems but that's the only part i needed help

thank you

[lime jolt]

So, CSRF is important and @csrf_exempt doesn't disturb it?

should i use @csrf_exempt everywhere?

Hi guys, I was looking for a Flask-React monorepo for my project and surprisingly I couldn't find any, so I made one instead. Check it out here and feel free to use it on your projects :)

Hi, i have a webpage with 4 div's acting as buttons, and using ajax i want to send which button was clicked, and then update my <p> tag which uses class=text1 to show that direction. (I also want to create a MySQL database and then send that data to that database, so if anyone can help with that it would be much appreciated)

At the moment clicking on the buttons work, and the value is shown because im using the 'get' method, but i dont want to get that data, i want to 'post' the button click to the server, and on success: change my <p> to the value of the button clicked. Havent really understood online resources about each of those things, so any input/changes you guys can give me would be much appreciated ❤️
#main.py

from flask import Flask
from flask import render_template
from flask import request
from time import time
from flask import jsonify
app = Flask(__name__)

@app.route('/')
def index():
    direc = request.args.get('direction')
    print()
    print('Direction:', direc)
    print()
    return render_template('index.html')

if __name__ == '__main__':
    app.run()   

#Javascript

$(document).ready(function() {
    $( "div[name='button']" ).on('click', function() {
      $.ajax({
        url: '',
        type: 'get',
        data: {
          direction: $(this).attr("id")
        },
        success: function(response){
          $(".text1").text(direction);
        }
      
      
      })
    })
  })

[obtuse robin]

i do this without using ajax if you would like to know

[hearty estuary]

Please

How

[obtuse robin]

var xml = new XMLHttpRequest();
xml.open("POST","{{url_for('new_data')}}", true);
xml.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
dataSend = JSON.stringify([new_data, type]);
xml.send(dataSend);

make a http request on the javascript

then for the python

[hearty estuary]

but then the content isnt dynamic

its static

like

page reload

[obtuse robin]

nope

it isnt

[hearty estuary]

how?

[obtuse robin]

here

let me show you the python

[hearty estuary]

oh wait

XMLHttpRequest

ajax uses that

Ajax is XMLHttpRequest

[obtuse robin]

oh lol oops

then it is ajax

[hearty estuary]

well

ajax is XMLHttpRequest + extra stuff

but same thing i guess

[obtuse robin]

oh wait heres the video i followed

https://www.youtube.com/watch?v=-XchxUQTcfQ

found it

[hearty estuary]

He doesnt show the end result tho

Only code devolopmenet

[obtuse robin]

wym, like he doesnt show it in action?

[hearty estuary]

Ye

[obtuse robin]

well you gotta experiment with it

[hearty estuary]

So not sure if its same functionallity as what i need

[obtuse robin]

its a good baseline

you just gotta change a few things around

[hearty estuary]

I dont see how he gets the button onclick

theres no function bound to it

No check of onclick

[obtuse robin]

you said you wanted to send a value to the db with a click then also put that value in an html element right

[hearty estuary]

Yes

This is how the webpage looks

[obtuse robin]

just put an onclick for a function that has the httprequest in it?

function send_data(new_data, type){
        var xml = new XMLHttpRequest();
        xml.open("POST","{{url_for('new_data')}}", true);
        xml.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        dataSend = JSON.stringify([new_data, type]);
        xml.send(dataSend);

        if (type[1]){
            if (type[0] == "song"){
            window.location = "{{url_for('song_page')}}";
            }
        }
    }

i mean this is what i have

[hearty estuary]

What is urs sending?

[obtuse robin]

im sending a song's spotify id

[hearty estuary]

Can you show ur html so i can see how you bind the send_data function to it

[obtuse robin]

sure

[rigid laurel]

This is very much not the modern way to do requests in js. I would highly recommend looking at the fetch API which is much more standards. This method hasn't been popular for probably a decade or more.

[obtuse robin]

oh damn rly

[hearty estuary]

why not modern?

[rigid laurel]

https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch

This is the standard way to do it

[hearty estuary]

okay

gotcha

thanks

[hearty estuary]

okay so u did add an onclick attribute to the div

[obtuse robin]

yes

[iron magnet]

Tested SQLModel for FastAPI. It’s a really good extension over “plain” SQLAlchemy and Pydantic.

i made a game with js, css, html, but i want to save the player's score into the django database automatically after each game. How would I be able to do that?

[obtuse robin]

what framework

[wind lotus]

django

[hearty estuary]

django is horrible i regret even trying it

i finally understood not to touch it unless your creating a huge ass project

wasted 4 days learning that shite

"learning" kek

[native tide]

hello to all, I just wanted to ask a small question I want to make a bot to do research on the txid of the bscchain for example someone has a track to help me start I am a beginner

welp, i think it's too late to turn back, i just spent 3 months trying to learn it and i just started getting the hang of it

[hearty estuary]

how fun

[hollow dragon]

is there anyone who could help me with connecting two tables in one database in Flask and SQLite?

[stable coral]

i want to make a webapp that uses the spotify api in python, is it better to download a library like spotipy or just use the web api directly in python?

[hollow dragon]

omg i just did it

I've been wondering: is there any particular single best order of these three in Django? Or something that should not be done?

    "whitenoise.middleware.WhiteNoiseMiddleware",
    [...]

ButtonClick.query.first()) prints <ButtonClick 1> always(first id)
ButtonClick(content=request.form.get('direction')) returns <ButtonClick lastID>

I dont want ID, i want to get the last item(direction) that was just added to db, what i would get if i were to post directly in SQL (SELECT content FROM button_click ORDER BY id DESC LIMIT 1;)

The reason i want this is because the response gets sent to a <p> and i want it to update according to the value(unnecessary i know but i want to anyways), how can i go about doing this using sqlalchemy?

class ButtonClick(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    content = db.Column(db.String(5))


@app.route('/')
def index():
    return render_template('index.html')

@app.route('/clicks', methods=['POST', 'GET'])
def clicks():
    if request.method == 'POST':
        direc = ButtonClick(content=request.form.get('direction'))
        db.session.add(direc)
        db.session.commit()
        print('To DB', direc)
        print('direc.query.first():', ButtonClick.query.first())
        return jsonify(direc)

$(document).ready(function() {
    $( "div[name='button']" ).on('click', function() {
      $.ajax({
        url: '/clicks',
        type: 'post',
        data: {
          direction: $(this).attr("id")
        },
        success: function(response){
          $(".text1").text(response);
        }
      
      
      })
    })
  })

Hey! i'm building a search and i'm querying for 'plugins'
I want to match my query with the most relevant plugins but I don't know how I should get started with that.
Here is what I have:

#app.py
@app.route('/dashboard/search/', methods=['GET', 'POST'])
def search():
    if 'username' in session:
        user = mongo.db.users.find_one({'name': session['username']})
        if user:
            if user['account_active'] == False:
                print("Account is not active.")
                return redirect(url_for('index'))
            else:
                pass

        print(request, request.args)
        if request.args['search']:
            query = request.args['search']
            l=os.listdir('plugin_base/plugins')
            plugins_D = [x for x in l]
            try:
                plugin_file = importlib.import_module(f"plugin_base.plugins.{query}", f"exec")
                plugin_conf = importlib.import_module(f"plugin_base.plugins.{query}", f"config")
                pfc = plugin_conf.config
            except:
                plugin_file = "None"
                plugin_conf = "None"
                pfc = "None"
            print(pfc)
            if query[0] in plugins_D:
                pass
        
        return render_template('dashboard/search.html', search=plugins_D)

I want to add the plugins that are most relevant to some sort of list so I can do something like this:

<!-- search html -->
 {% for result in search %}
 <h2>Plugin Result</h2>
    <div class="card">
       <div class="card-body">
       <h5 class="card-title">{{ search['name'] }}</h5>
       <a href="/dashboard/plugin/{{ search['name'] }}" class="btn btn-primary">Use this Plugin</a>
    </div>
</div>
{% endfor %}

I think it's pretty easy to understand what I'm trying to do.
Thanks in advanced! :)

Is there any visible problem here? Or should I check somewhere else? I am trying to make a login system, the user exist but it leads to fail. I tested, it can get the username and password for x and y.

I'm using django rest framework. In the comments, you can see how I want to design my API

https://dpaste.org/wdivE

this are my models and views.py

I don't get how I can have my routes set up so it's /api/decks/<int:pk>/cards <-- lists all cards within that deck

how does that work with API

[opal verge]

Hello @native tide
You need to create an urls.py into your app and list your views into that field. Later, list on urls.py of your project your urls.py of the app

[obtuse robin]

you sure youre supposed to use request.post

because youre not posting anything, youre getting the information from 'username' and 'password'

the request method is still post though

probably can just do request.form['name']

[native tide]

do u know what i am saying?

  class RecipeSerializer(serializers.ModelSerializer):
    rt = serializers.SerializerMethodField(source="ingridents",read_only=True)


    def get_rt(self, instance):
        try:
            return json.loads(instance.ingridents)
        except:
            print("Error")
    
    class Meta: 
        model = RecipeModel
        fields = '__all__' 

Can someone help me i'm trying to convert json into list but it returns null

    "rt": null,

though there are data in ingridents

    "ingridents": "2 cups cooked chicken chopped\r\n½ cup mayonnaise\r\n1 stalk celery chopped\r\n1 green onion diced (or chives or red onion)\r\n1 teaspoon dijon mustard\r\n½ teaspoon seasoned salt\r\npepper to taste\r\n1 teaspoon fresh dill optional",

I'm trying to convert this ingridents to something like this

  "ingridents": [
                        {
                           "2 cups cooked chicken chopped"
                        },
                        {
                          " stalk celery chopped"
                        },
                        {
                            " teaspoon fresh dill"
                        },
                        {
                            "  green onion diced "
                        },...
                    ]

that's ingridents in models.py
ingridents = models.TextField(default="")

Hey 👋 , is anyone working with Django channels in real-life projects?

How to use python for website backend?

[opal verge]

You can use Fask or Django. They're free Frameworks

[covert yew]

flask, Django or fastapi

[copper juniper]

Thanks

[copper juniper]

Thanks

[rigid laurel]

you need to use something like Pillow to generate the jpeg. Another option would be Jinja+Markdown+Pandoc to make a pdf, then convert the pdf to a jpg

[agile pier]

i m trying to create a chatbot using django as the backend, but i m having trouble showing the responses

when giving the result for a query, how do I also show the previous chat history?

[dusk portal]

I can generate image by pillow that's not the issue but I want image to give dynamic data and only some data to be changed (see the above ss) I want other things (i.e instructions or qr) to remain untouched

[rigid laurel]

then write some code to do that?

def make_image(dynamic_data):
    static_data = load_your_static_data_here()
    <pil code that munges the static and dynamic>
    return img

[hidden kettle]

hello

Any Django dev here who has worked with both Django & React?

[serene prawn]

I've worked with django for some time but we're trying to migrate our codebase to fastapi

Didn't work with react specifically but it's similar to other frameworks

[hidden kettle]

Can I ask you some questions related to Django & DRF?

[serene prawn]

Yeah

It's better to ask your question right away so people could see if they can help you or not

[hidden kettle]

I'm getting stuck when trying to build a feature for my Saas that allows users to log out of respective sessions or all sessions.How can I implement such a thing? Here's the overview of what I'm trying to build. I took this inspiration from Khalti which is a payment gateway of my country. It's built with Django & React. I will also create a mobile app.

How should I keep track of mobile logins with my app version and mobile device name? This is the API response of sessions. How can I implement this in an exact way?

What auth mechanism should I use here?

sessions?

[serene prawn]

You can use pretty much anything as underlying implementation - sessions, tokens, jwt's, with any of them you would have to keep track of active tokens so people could invalidate them

It might be simpler if you choose to just invalidate all tokens before a specific date, since it won't require you to keep track of all active sessions

[hidden kettle]

Should I use DRF token auth/

?

[serene prawn]

I'm not familiar with django packages really

[hidden kettle]

I got the general idea. Thank you

[serene prawn]

I think we can discuss the specifics, other people might help you too

Invalidating user sessions should be a solved problem at this point

[hidden kettle]

I would be happy If someone joins the discussion

hi, how can i localize the datetime form fields in my django app?

my server is 4 hours behind my actual timezone, and when i pass a time of 8pm in my local time to the form it appears as 8pm in server time in the database. But ideally it should appear as 4pm in server time.

how can i fix this?

i've set the USE_TZ = True setting in settings.py too
