why does my flex containers never work?

viral oyster
#

Its kinda silly question i know but just wanna know that-
When we press ctrl + shift + c in any webapp it shows that web code.. If anybody make that change, would it be run on that particular user???
Won't it be?

wicked elbow
#

if they modify anything in the rendered html, itll only affect their display. but its really not highly important.

Oh got it tnx..

Hey, i'm not too sure if this is the right place but i'm wanting to use electron with python to build an app for a game what is the best way to communicate between electron and python?

#

or is there a better way in general to make a desktop app with python?

halcyon lion
#

if its some simple app you can use tkinter

#

if you aim to make it a bit more fancier i'm not too sure tkinter is the right tool 😄

candid peak
#

I'm kinda already running into trouble lol

#

my flask app works perfectly fine in browser

#

but when i import it into electron

#

none of the CSS or images work

Hey @timid spruce!

It looks like you tried to attach file type(s) that we do not allow (.zip). We currently allow the following file types: .3gp, .3g2, .avi, .bmp, .gif, .h264, .jpg, .jpeg, .mkv, .mov, .mp4, .mpeg, .mpg, .png, .tiff, .wmv, .svg, .psd, .ai, .aep, .xcf, .mp3, .wav, .ogg, .webm, .webp, .flac, .afdesign, .m4a, .csv.

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

does anyone here have experience with Heroku and django?

Using DRF your request needs the Authorization header with value Token <your_token> (Token authentication)

why are you using python 2 😩

Hello

#

did anyone used ever AXIOS to get data from Rest API

halcyon lion
#

nope 😄

#

i have 1 stupid question

#

i have a base view that i load header and footer

#

i pass a form on the footer

#

but when i extend the page i have to pass the form again every time i extend the page

#

which seems not very pythonic

#

how do i fix that

#

nvm i am dumb 😄

pearl tulip
#

When I go to the page this is on it says "Method Not Allowed"
How do I use a POST request properly
(Python Flask)

def tools():
    if request.method == "POST":
        return "<h1> Submited </h1>"

    return """<form method="POST">
    Language <input type="text" name="language">
    <input type="submit">
    </form>"""```
quick cargo
#

your browser sends a GET request

#

your endpoint only allows POST

I have problem with cors headers in Django Rest
have followed https://pypi.org/project/django-cors-headers/
but still when i send get request using AXIOS i have issue with cors

i have resolved this... my installation and configuration was correct.. however due fact that I'm using anaconda as Venv manager

django-allauth is confusing the shit out of me
i'm trying to get it working with discord oauth, but i have no idea how to get any data from the response
i just want the list of user guilds and the username, nothing else

toxic flame
#

Hey guys, so I basically have a list of inputs with the same id and name, is there a way using django's request.POST['id'] getting all it's values and looping through them?

dim wyvern
#

Would anyone be able to help me with a Flask issue?

#

I'm trying to use build a search tool but keep running into a Method Not Allowed on submit request

toxic flame
#

on django there are needs of csrf token on post requests, not sure about flask.

dim wyvern
#

yeah I got that part at least I think

#

just initalized a secret key, no more csrf token error

cold portal
#

I ran into an issue where I had to put the token within the table

dim wyvern
#

I'm practically using something I built a year ago, so not sure why an error keeps happening

cold portal
#

Rather, doing so fixed my issue

dim wyvern
#

hmm not sure what you mean by token in the table

@app.route('/search')
def search():
    global data
    form = SearchForm()
    if form.validate_on_submit():
        form.search.data = form.search.data.lower()
        if form.search.data in sorted_words:
            data = form.search.data
            return redirect(url_for('search_r'))
    return render_template('search.html', title='Word Search', words=sorted_words, form=form)
cold portal
#

I meant form, not table. Sorry about that.

dim wyvern
#

ah ok gotcha, thanks i'll try it

cold portal
dim wyvern
#

ok that didn't seem to work. what I tried was

class SearchForm(FlaskForm):
    app.config['SECRET_KEY'] = '62c04aebd965c494be687413770b91cc'
    search = StringField('Search', validators=[DataRequired(), Length(min=2, max=20)])
    submit = SubmitField('Search')

but the app var doesn't exist here, so still unsure what you meant lol

cold portal
#

For index in request.POST[‘id’]:
Do something

#

My issue resulted in an error related to post method because csrf token wasn’t within the form submitting/posting

#

Basically it was a variable on the page but not in the form if that makes sense

toxic flame
#

It only shows the first value, the others aren't showing up

#

This is the last problem I have then I can get paid 😭

toxic flame
cold portal
#

can you show me an example of the data structure?

#

print out request.post['id]

#

I'm trying to figure out why datatables column titles are misaligned with the row data until i click on the page somewhere.

i need help getting flask to shut up

#

i thought flask was the lighter easier one

#

i mean django is heavy obv

#

but i though flask was much easier than django

toxic flame
#

Yea tbh they are all the same just that django is alot heavier even if you want to build small stuff

#

I prefer django over flask though

                msg.html = render_template('email.html', postID='reset password', first_name = email_data[1],token = totp.now())
                mail.send(msg)
                print('Sent successful!')
                break```

for the last 4th line, token = totp.now() is there a way to call the one time password instead of the function?

well Im using flask, thus, need set token = 'something' for me to retrieve out

@rose field it depends on what you’re building

#

is more that Django comes with batteries included (templating engine and ORM, for example)

#

so if you wanna make something that needs these you’ll need equivalents for Flask anyway

weary bough
#

can someone tell how to make this kind of a user system?

#

I m confused whether to use proxy model or AbstractBaseUser.

cold portal
#

Seems you can use what's included and dont need additional models

#

For custom user flags i used AbstractUser

#

from django.db import models
from django.contrib.auth.models import AbstractUser

class CustomUser(AbstractUser):
is_a_special_user = models.BooleanField(default=False)

what is wrong? what?

result array prints a value btw, it's not empty. and it is a url of the images. I checked

but it just shows nothing.

result = []

if images:
    result = map(lambda x: upload_url + x, images)

    print(list(result))

return render_template("index.html", form=form, result=result)

html:

<form method="POST" enctype="multipart/form-data">
    {{ form.hidden_tag() }}
    {{ form.photo }}
    {% for error in form.photo.errors %}
    <span style="color: red;">{{ error }}</span>
    {% endfor %}
    {{ form.submit }}
</form>

<br>
{% for image_url in result %}
<img src="{{ image_url }}" />
{% endfor %}

#

map will return a map object and that is an iterator. In this case, you'll exhaust it when you iterate over it.

#

So, by creating a list for your print, you'll take all items from the map object and it's exhausted after that. It won't return any more elements.

#

!e

my_map = map(lambda x: x + 1, [1, 2, 3])
print(list(my_map))  # the results
print(list(my_map))  # empty list

Can u do a single detailed message? lemon_sweat

echo mesa

and it doesn't work, I used del to delete it but when I create the the form again usingdata=data it loads the old data for some reason

pearl tulip
#

"internal server error " happened

urban whale
#

So I think it's an error of the minecraft server

pearl tulip
#

or failing to run the batch file

#

that starts the server

#

there is a pause in the batch script

#

i could remove that

echo mesa
#

I'm having trouble using WTForms with Flask, I'm trying to edit the data of a form, after a LOT of trying I found something that works when loading the page, but when I "refresh" it it doesn't work, I'm pulling a schedule from a database,
when loading the site, I set to load specific schedule of someone but I have buttons that reload the site and try to load different schedule, but the problem is it for some reason not updating the page when I'm trying to load a different one

data = {'TwoDTable': template_previousSchedule['TwoDTable'], 'changed': None, 'submitToDB': False}
    print('data' + str(data))
    template_form['schedule'] = forms.scheduleTableForm(data=data, meta={'csrf' : False})
    print("before")
    print(f"template_form['schedule'] is:\n{template_form['schedule'].data}")

This returns

data{'TwoDTable': [{'Lesson': 'אנגלית'}, {'Lesson': 'אנגלית'},.......]}
before
template_form['schedule'] is:
{'TwoDTable': [{'Lesson': 'אנגלית'}, {'Lesson': 'ספורט'},.........]}

The problem is data is the correct thing to load but the thing printed after before is incorrect and I don't get why

This is my site: https://prnt.sc/wepfau
the top selects and the first red button is used to refresh the page and try to load the new schedule

Hey @echo mesa!

Uh-oh! It looks like your message got zapped by our spam filter. We currently don't allow .txt attachments, so here are some tips to help you travel safely:

• If you attempted to send a message longer than 2000 characters, try shortening your message to fit within the character limit or use a pasting service (see below)

• If you tried to show someone your code, you can use codeblocks
(run !code-blocks in #bot-commands for more information) or use a pasting service like:

Hello everyone, i am facing a problem with django and i don't know how to solve it, i will explain the best i can my problem :
i have two classes : tag and media.
I need to define a media with a tag attribute, i defined a foreignkey in the class media to collect the tag value, but since i would like to have different tags, i am asking you if there is a way to give in the admin panel the choice to add as much tags as he wants...
Thank you so much for your help!

So here is the image i talked about
What do you think? The api is a HTTP api server, ws = websockets. And all the clients are connected to a websocket, but it can be on a diff port/host

📎 architecture.png
quick cargo
#

DB is completely i relevant in this case

sudden grail
# quick cargo

And what is the gateway? It's the websocket server with some http routes?
So you hit the API with a message it performs an other http request to the gateway which performs socket emitting?

quick cargo
#

litterally can just be another http request

sudden grail
#

But then you have to authenticate twice

#

or?

quick cargo
#

hmm?

sudden grail
#

what if someone sends request to gateway directly?

#

a "hacker" or somehing

quick cargo
#

they cant

#

just stick it behind a private ep

#

what we do lol

sudden grail
#

ohhh

quick cargo
#

for us our api for comms is done on the same system as the gateway

sudden grail
#

and only the API sees this gateway

quick cargo
#

yeah

#

the magic of localhost

sudden grail
#

yeah got it

quick cargo
#

or litterally any virtual netowork

sudden grail
#

nice

#

and why is that better than redis?

#

you said redis is slow

#

but, is that faster?

sudden grail
quick cargo
#

well we ditched all of our redis called and saved about 200ms of latency per request

#

dont use redis where it isnt needed

#

its just adding another layer of calls and processes that you dont necessarily need

sudden grail
sudden grail
quick cargo
#

fine?

#

postgres is fast, asyncpg is fast not really and issue

just use PIL or smth to handle the metadata

I'm trying to figure out why datatables column titles are misaligned with the row data until i click on the page somewhere. Any ideas? I’ll try just about anything at this point.

native tide
#

@cold portal Have you set their width to match in the CSS

cold portal
#

Actually, no, I haven’t touched CSS. Using bootstrap4

#

Interesting that it would correct itself on click

#

Thanks for the tip. I’ll look into it

native tide
#

I'd just say give the columns an extra class which has a set width

#

Or have the labels (device info) and the value below it (NSA2600) in the same row & column as eachother

#

Then give the value column a class of w-100 so it expands to the width of Device Info

#

@cold portal

cold portal
#

What do you mean in the same row & column as each other? I think they are. Both defined in datatables.columns[]

#

Each column defined has the title in it. I had the title labels set in html but had the same problem.

#

I’ll see about trying to apply another class with a set width. Setting the width in the column definition didn’t help

Im trying to show the user picture in Django but not working. already added static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) and i checked the src and its correct but its still not working.

gaunt marlin
nimble epoch
# 
MEDIA_URL = '/profile_pictures/'```
nimble epoch
#

and actually in the src of img tag its correct but i dont know the problem.

#

and funny thing that this is the first time

gaunt marlin
#

BASE_URL / 'profile_picture' is not how you concat a string O_O

nimble epoch
#

maybe this is my chance this time

nimble epoch
gaunt marlin
#

check developer console by pressing f12 go to console and what error it's returning

nimble epoch
#

in its own docs this is written that use it like this

nimble epoch
gaunt marlin
#

then the path is correct

nimble epoch
#

yep

gaunt marlin
#

are you using FileField in model for it?

nimble epoch
#

and wait wait of course it returns a 404 error

gaunt marlin
#

why you said no error earlier...

nimble epoch
gaunt marlin
#

show the error?

nimble epoch
#

404 error. it cant find the image from the path

#

but already i said its correct

gaunt marlin
#

can't you just copy paste the red line in here?

nimble epoch
#

its orange lol

gaunt marlin
#

404 errors have red warning

#

how it's orange?

nimble epoch
#

it is i dont know

gaunt marlin
#

try to go the url, does it show the image?

nimble epoch
#

nope 404

#

i already done all the solutions

gaunt marlin
#

you need to post what you have done in your code

#

first by showing the folder path of MEDIA_ROOT

#

or paste the url in here to see

nimble epoch
#

ok wait

nimble epoch
#

emmm @gaunt marlin thanks bro and appreciate your time. its working now.

proud kiln
#

Okay so I'll put my conceptual question here

#

Regarding Django.

What's preventing me of using ajax request to get fully rendered html back from Django and inserting it in a div?

This feels much more versatile to me over using include tags...

But feels "hacky" to me...

vestal hound
#

but the whole point of Django is that it returns fully rendered pages in the response

#

if you want to have dynamic content, might as well just write a web API

zinc hill
#

Question: what do you call a web application that basically manage databases
like a front-end that can send api request to delete, create and edit users?

toxic flame

#

I guess so lol

for such a simple application it took way longer than it should

I need help. I want to insert a swf file from my computer and go into the game, but the server loads its swf file. Give advice what

vestal hound
proud kiln
#

I understand the point. But after using some other frameworks, namely vue

#

This seems so much more powerful to be used this way

#

I can re-render a piece of html with dynamic content

toxic flame
#

well ajax can be really bad for people with bad internet idk

proud kiln
#

Well... Who has bad internet these days? I dont want you using my website

#

😂

#

How is ajax any different from a rest api internet wise?

copper storm
#

What is Computational Thinking? can someone explain this to me where I can understand it.

proud kiln
#

@vestal hound but i can render just a snippet of html, like a form and then send it over to the page

#

And update a div with it

#

But this feels so "hacky" xD

gusty sphinx
#

dm me if you have high html knowledge

zinc hill
#

@gusty sphinx bruh just ask the question

Hello, everyone. Is picking a font even an issue these days? Can I just pick what I want? Last time I was doing web stuff was in the mid 2000s.

Which web-development framework would you recommend for a beginner, Flask or Django. Also for the web framework you recommend, where would you say is the best place to learn how to use it. Lastly, for web-development do I have to learn any additional languages like javascript, css, or html for front-end, if so which should I start with.

twilit needle
#

1.django
2.django docs or programming with mosh's tutorial chapter on it in his 6 hour long course, I learnt from it, and of course, the well written docs

  1. First master the backend with Django, if python is the only language you know. Then I would say you learn javascript. CSS and HTML aren't "programming languages", they are just tools for presentation and can be learnt comparatively quickly. You'd need practice to improve your presentation though
#

@plain haven

plain haven
#

@twilit needle Thank you lots! After practicing python for a while I wanted to go into web development and didn't know where to start. This helped point me in the right direction

wicked elbow
#

how do you call this and set the value like you do in python?

function something(a=false, b=false) {
}

something(b=True)

cause im just getting errors, ive googled it, but it never mentions the calls to set the variables separately

gaunt marlin
wicked elbow
gaunt marlin
#

so something like this will work

function something(**kwargs) {
    b = kwargs["b"]
}

something(b=True)
#

you didn't say js in your question

wicked elbow
#

ah my bad, copyied it from another discord that is js specific

gaunt marlin
#

(){} can be anything from C to javascript

wicked elbow
#

i know in python, if you set kwargs in the define then you can set them in the call by doing function(b=true). so didnt know how to do it in js

gaunt marlin
wicked elbow
#

yea, i knew about spreads too. thank you

fierce sphinx
#

What is recommended for a site's backend in python? Can i use simple http server or i should use something else?

gaunt marlin
fierce sphinx
#

Oh

fierce sphinx
#

We can do it with these framworks or sth else?

quick cargo
#

sql server as in MS sql server?

fierce sphinx
#

I dont know probably mysql or sth.

quick cargo
#

Django Supports pretty much only SQL with its orm (SQlite, MySQL or Postgres), FastAPI or any async framework i would recommend using postgres only and asyncpg

gaunt marlin
quick cargo
#

Flask can support pretty much anything cuz its what ever you implement

fierce sphinx
quick cargo
#

same with async frameworks for that matter but their drivers are very limited and asyncpg is about the only decent one as of right now

fierce sphinx
#

So flask is a good one?

quick cargo
#

depends what you're doing but its a pretty solid choice

cloud gulch
#

Flask will give you a lot of freedom and therefore is really powerfull. Django is more constrained but it makes it harder to make errors.

gaunt marlin
#

flask is flexible, django if you want to make something fast, fastapi mostly use to make api(figure)

fierce sphinx
#

So Django is easier to use but flask i can do more

quick cargo
#

Ehh its mixed

fierce sphinx
#

I understand now

quick cargo
#

they are bascially the same

#

Django just has stuff already added

fierce sphinx
#

Maybe we try django first

gaunt marlin
#

Django faster to build a website but it's hell to customize and understand all of it

cloud gulch
#

Yea in the end the code you write it what makes the difference.

fierce sphinx
#

And what do you think about making my own http server? Is it hard to connect to db?

quick cargo
#

i wouldnt make your own http server unless your seriously know what you're doing if its for production

cloud gulch
#

That would mean writing a lot of very interesting, critical and hard code. which is a good idea to learn stuff and bad idea to make things that works

gaunt marlin
#

security a big thing if you doing production

quick cargo
#

Been re-writing my http server in Rust for python 😔 Just takes freaking ages to test though

#

need to add http/2

fierce sphinx
gaunt marlin
#

you are free to reinvent the wheel if you want 🙂

fierce sphinx
#

I never used db neither so i dont know how hard is it to connect a db to my http server

gaunt marlin
#

if you connect to db from http you have to handle each transaction, re-authenticating,... and a lot more

quick cargo
#

DB handlers are about 100x harder than writing a http server

#

i would just use a pre-made driver

gaunt marlin
#

handle transaction without it blocking each other will take ages

quick cargo
#

python has a pretty good selection of drivers for your flavour of db

cloud gulch
gaunt marlin
#

yes like how i described above writing https server is like reinvent the wheel, it's good but not needed 😄

cloud gulch
#

In the mean time, for study, build you own http server, db driver, language, OS, all of it is really interssing and will allow you to use the premade ones better.

gaunt marlin
#

yes better understanding of the framework you will be using

fierce sphinx
#

But i think we will use django or flask first

#

Btw i have one more question

#

we will need an sql database i considering mysql prostgresql, mongodb but idk

quick cargo
#

postgres 100% if you're going with sql

fierce sphinx
#

Ok thanks

quick cargo
#

mongodb is fine if you wanna just go simple and easy

#

just depends

fierce sphinx
#

Basicly just for local things

#

Just a simple project a simple page etc

fierce sphinx
quick cargo
#

if you want really simple just use SQLite

#

its pre-installed with python

#

so no external server needs setting up etc...

fierce sphinx
#

Oh thanks then

fierce sphinx
quick cargo
#

Thats a bad idea security wise

#

you can

#

but you shouldnt

fierce sphinx
#

WE dont want to host the server

#

Just in localhost

#

But we wont then

cloud gulch
#

What's the purpore of your project ?

fierce sphinx
#

Then how could we work with the same content?

#

Just to make a site with backend and sql

quick cargo
#

you dont really need to have the same data per say

fierce sphinx
#

I dont know if he will want to host it so i wont share anythinglike the databsae

cloud gulch
#

sharing the content via the sqlite file over github can work but it's ugly and will become a hassle when you have a lot of data

quick cargo
#

its just a test site n localhost so not a maisssive issue to just replicate data

fierce sphinx
fierce sphinx
#

thanks guys

cloud gulch
#

You can always just dump the db and share it via mega/whatever

fierce sphinx
#

Thanks btw if i use sqlite now later i can swap to other sql server if i want to host? or i can use sqlite for a real site?

cloud gulch
#

You can mostly swap sqlite with other sql databases. You can also host sqlite if needed but i'd recommend postgresql if you want something online.

fierce sphinx
#

Thanks

ValueError: View function did not return a response

this one?

gaunt marlin
#

yeah that

#

you need to return a response in your view

#

what happen if it doesn't go into if statement?

passw = request.form.get("pass")
        if passw == "1234abc":
            if request.form["arduinocontroller_left"] == "left":
                subprocess.call(["C:/Users/mrxbo/Desktop/Controller/ayylmao.bat"], shell=True)
                return render_template("controller.html")
            return render_template("authent.html")
#

it will return None

pearl tulip
#

what is not going into an if statement?

analog arch
#

when pass != "123abc" and does this ever reach the controller page?

gaunt marlin
pearl tulip
#

I was thinking of loading the html file "controller.html"

#

in the return

gaunt marlin
#

yeah probably it ran into that

#

try printing out those compare variable and see if it satisfied the if condition

pearl tulip
#

so instead i write
for testing?

return"<h1>Test</h1>"```
gaunt marlin
#

that not a response object

#

that is just a string

pearl tulip
#

how about

return redirect("controller.html")

?

#

or is that still a str

gaunt marlin
#

i haven't touch flask in a long time so i don't know redirect() is a reponse object

#

redirect supposed to accept url as argument

analog arch
#

if request.method == "POST": But what happens when it receives a GET request. It has no response to return

pearl tulip
#

how can I solve this? do I replace "POST" with "GET"?

#

or ["POST", "GET"]

gaunt marlin
#

if you sending data, use POST

#

if you getting a page or info, use GET

analog arch
#

just place a return render_template("authent.html") on the same indentation with the if statement

if request.method == POST: ... ... return render_template("authent.html")

I am getting this error in reactjs:

Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

Check the render method of `NavigationBar`.

My all exports and imports are all correct, I dont know why this error is coming i have tried putting export default in from of defining the components but still no luck. Please help.
The imports in NavigationBar:

import React, { Component } from 'react';
import './NavBar.css'
import {Container, Navbar, Nav, NavItem, NavbarBrand,} from 'react-bootstrap'

@native tide I'm using Django as Backend but only for the users and data, in the other hand, Django isn't good for livestreaming and what I need to do is to capture the video and applying a Machine Learning algorithm for detection, all that in real time

I was looking for some information and everyone I read said Django isn't good for that

django has websocket support through channels. I haven't used it so I can't help much with it

Quick Django question, I created a "firstapp" and so I added it to the settings.py in the INSTALLED_APPS section, however when I save it it tell me that there are no module named "firstappdjango"... any idea why the name changed? I checked a few places and I can't figure out what I'm doing wrong.

vestal hound
safe sorrel
# 
# Application definition

INSTALLED_APPS = [
    'firstapp'
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
vestal hound
#

@safe sorrel you're missing a , after firstapp

safe sorrel
# 
ModuleNotFoundError: No module named 'firstappdjango'
vestal hound
#

so when you have two strings next to each other Python concatenates them

#

i.e. 'left' 'right' is the same as 'leftright'

safe sorrel

-_- yup I see it now

can anyone help me learn about foreign keys, how to set them, im seriously confused about them... for example

class Messages:
  from = models.CharField(max_length=200)
  message = Models.TextField()

class User:
  ...
  messages = models.ForeignKey(Messages, on_delete=models.cascade)
``` how are they linked? i dont understand the relationship... one user, can have multiple messages, but how is it known which message belongs to which user?
#

and the documentation sucks

#

or is the link backwards, Messages needs an owner and linked the the User table

#

not the right place to ask that question, this is development, not scraping

calm light
#

my bad

wicked elbow
# calm light my bad

from what i can tell scraping from flickr is against ToS so most people arent gonna be able to help you in here anyways

gaunt marlin
calm light
gaunt marlin
#

the only way i can think of is reverse relation but that easily cause conflict

wicked elbow
gaunt marlin
#

yes

#

when you declare foreign key you have to think in reverse with ORM

#

it's the concept of foreign key

#

one-to-many is only on graph

wicked elbow
#

but how do i set that in create? i just pass the owner id to the messages? which links it the proflie based on that id?

gaunt marlin
#

yes you have to set id of the user

#

if you look at most message data it has a column user_id

#

usually in a request you can get request.user

wicked elbow
#

yea, but it if person b was sending a message to person a then b wouldnt have access to user a other then from the form being filled out. thats what confuses me

#

technically, the message writer and the recipient would both need to be linked

gaunt marlin

ya, but i can post a value to it just like any other query right? nothing fancy on the back-end i have to do right?

i dont know anything about flask or discord.py, but someone might know there as well. if your running both from the same server and not communicate it shouldnt be an issue, just run them in separate cmd lines. if you want them to communicate, discord.py would know more about that then anyone that only knows flask. just offering you help

maybe look into discord.py code to see which function you need to import into flask

yeah

it's an url function right?

#

Nope

gaunt marlin
#

@app.route("/webhook", methods=["POST"]) <-

native tide
#

wait what?

tulip kite
#

I'm not sure but maybe you need a return statement for the webhook function, because you're only checking the request method without doing any response

#

172.18.0.1 - - [07/Jan/2021 09:13:49] "GET /webhook HTTP/1.1" 405 -

#

this part of the error is normal because you are only checking for post requests, you look like yout tried typing in a url so you get a get request error, your code only checks for post requests

Took more than a MONTH WTF

wicked elbow

lmao that is a while, i dont think ever seen the post

gaunt marlin
wicked elbow
# gaunt marlin are you talking about the admin or others?

no, i set a to and from field in my model, i want to filter the results when the to or from filed contain the user, so for instance, me and you are talking, the would make you user 1 and me user 2. i want to see both sides of the message, so i need to see both to you from me and from me to you. if you understand what im saying. when i query 2 it should look for 2 in both to and from not just to and not just from.

gaunt marlin
#

i don't understand what you just typed

#

please shorten the description without too much repeating words

#

are you making like a chat application?

#

or an invoice system?

wicked elbow
#

how do i search in multiple fields for the same result. filter only accepts one query. i need SELECT * FROM table WHERE sender or recipient = userid

#

messages system similar to email, but much simpler

gaunt marlin
wicked elbow
#

ah ok, funny thing i actually looked at the page, just looked like a lot to take in at once

#

it worked, thank you

#

alright, now we are getting somewhere, ive linked tables using ForeignKey and then serialized them with the usernames from profile. and it worked correctly

wicked elbow
#

this project looks huge, ive built 7 complete back ends for it to run, 7 actions, 7 reducers, and like 30 components. so much code.

I was trying again

but only 1 of them runs

#

idk what to do 😭

wicked elbow
#

do them in seperate programs. and just have them communicate via ports.

native tide
#

communicate via ports?

wicked elbow
#

well ports isnt the correct term, but for instance, i communicate to my server by making post or get requests. imagine a website pulling items from a database. id call a get request to http://localhost:8000/api to pull the data. then to create a new message to a database id send a put request to http://localhost:8000/api/add. thats what youd do if you needed your discord bot to save stuff to a database on your server. id assume youd use request in python. but i dont know specifics for your case

Hi there! 🙂
Anyone with GraphQL experience.... Why do some articles recommend that instead of throwing application errors, you return them as a response?
Ariadne recommends that: https://ariadnegraphql.org/docs/error-messaging
I find it highly inconvenient: many unions, extra code, and importantly, API users will be able to ignore errors.
so.. .why?

Would like to get data from a csv file one row at a time every time getCSVData() is called through the JS file. Unfortunately I only get the first value on repeat.

<script>
        const xtab = [];
        const ytab = [];
        function getData() {

            //const time = {{csvtable_time}};
            const price = {{csvtable_price}};
            return price;
        }
        Plotly.plot('chart',[{
            y:[getData()],
            type:'line'
        }]);

        var cnt = 0;
        setInterval(function(){
            Plotly.extendTraces('chart',{ y:[[getData()]]}, [0]);
            cnt++;
            if(cnt > 500) {
                Plotly.relayout('chart',{
                    xaxis: {
                        range: [cnt-500,cnt]
                    }
                });
            }
        },1000);

Does someone know how I can solve this?

python file:

@app.route('/dashboard/<string:currency>', methods=['GET','POST'])
def show_plot(currency):
    time, price = getCSVData()
    return render_template('chart.html', title=namescurrencies[currency], csvtable_time=time, csvtable_price=price)


def getCSVData():
    with open('ltc.csv','r') as f:
        csvdata = [row.strip('\n').split(',') for row in f][len(xtab)+1]
        time, price = str(csvdata[0]), float(csvdata[4])
        xtab.append(time)
        ytab.append(price)
    return time, price

# native tide Would like to get data from a csv file one row at a time every time getCSVData()...

I'm not the best at Javascript, but from what I can see, your getCSVData() won't remember where it left off the second time you call it. It'll always start from the beginning.
I'm also not the best programmer, but one of the things you can do is keep track of the offset in the Javascript. So your javascript calls getCSVData(1), getCSVData(2), etc.
But that gets REALLY expensive REALLY fast, because now getCSVData() has to read everything and jump to the line you want.
Are you able to read the entire CSV, return it as a JSON object and let Javascript handle the rows one by one?

Very new to Django here and having issues with creating an app:
1- python3 manage.py startapp firstapp - ok
2- add app in INSTALLED_APPS in settings.py - ok
3- add app in urls.py:

from django.contrib import admin
from django.urls import include, path

urlpatterns = [
    path('firstapp/', include('firstapp.urls')),
    path('admin/', admin.site.urls),
]

Gives me the following error: ModuleNotFoundError: No module named 'firstapp.urls'

#

I believe that normally I should get that error and even be able to run python3 manage.py migrate

#

**normally I shouldn't get that error

@safe sorrel go into your firstapp folder and create a file named urls.py

hey im curious
do you guys know how flask sqlalchemy handles the boolean values
because in my actual db, it's stored as tiny int
and i know tiny int is either a 0 or 1 value
so does the orm actually know to use 0 or 1 values?
and I guess if I'm doing conditionals based on this boolean value I need to use 0 and 1s as the constraint
instead of True or False?

    return render_template('/admin/products.html', user=User().query.first())

Does anyone know an easier way to pass through user to all admin routes? Tryna clean up some code, and wondering if I an make this easier

#

There is about 12 different routes inside Admin

swift sky
#

im not sure i understand your question

#

are you looking to find out how to restrict views based on position title?

#

oh I see you're using blueprints, I'm unfamiliar with those and how they work, though I do know their purpose

#

i do stuff like this

# 
    @login_required
    @require_title(['Supervisor', 'Trainer', 'CEO'])```
#

using the login_required

#

flask login module

past cipher
#

Basically, I have around 12 @ admin routes. Each time, I have to pass through user=User().query.first(). I wanted to know if there is a way I can write one line of code, and pass through User to every Admin route

past cipher
#

in alchemy

swift sky
#

what that does is basically restrict routes based on user title

#

so you just make your view and restricted based on titles

past cipher
#

I understand that

#

But that is not what I need

#

I need access to the user variable in Jinja

Hello! I have some problem with my flask application, when i use gunicorn with meinheld worker. I have tried to do the job with eventlet worker, and it works, but does anyone knows, that will this change cause any significant performance downgrade? And are they actually do the same thing?

quick cargo
#

eventlet will be more performant than a standard threaded worker

thorn oxide

and I have read, that "gevent is inspired by eventlet but features a more consistent API, simpler implementation and better performance." (on it's pypi site). So wich one should I use?

Javascript is making me cry

# native tide Javascript is making me cry

Personally, I think file operations (opening/closing files) for x number of lines is going to be more expensive. The more lines you have, the more times you'll have to open/close that file. Opening/reading it once and manipulating it in memory would be faster in comparison as the number of lines increase.

native tide
#

Thanks for the tip! Really appreciate it 🙂

#

It's just that I cannot figure out whether it's expensive or not yet because it isn't working 😛

pearl quiver
#

File operations are traditionally expensive.

native tide
#

I mean, it almost works. I only have one value in my plot now

native tide
pearl quiver
#

@native tide have you considered using a database rather than using a CSV? The only reason i suggest that is because if you can keep track of what your javascript already has loaded, you can query for additional info

#

example: if your data has an incremental primary key (a number that keeps going up), then your javascript can have a loop that will load everything after x

native tide
#

Yeah, I considered that but the storage space was a limiting factor. Didn't want to upgrade as it's just for a school project. Currently working on data analytics but showing a nice plot on a local website has definitely been the most time consuming part as I'm basically javascript illiterate

pearl quiver
#

or if you track the time of your entries and the time of your query

#

@native tide i think a sqlite3 shouldn't take up too much space

#

but i mean, lol, yeah, there are lots of ways to optomize it, but if you need your chart to update every 20 minutes, then maybe you can make a new CSV every 20 minutes

native tide
#

I mean, I have CSV files of 50MB... so I doubt whether sqlite3 can handle that

pearl quiver
#

i think you would be surprised at what sqlite3 can do 😄

#

it's not a pushover

#

it's not the greatest if you have a million hits at a time

#

but if it's a local thing and you have like, maybe 100 people at a time just reading, it's not too bad

native tide
#

Hahaha it's ok, I tried postgresql before but it had a storage limit of 10k rows so that was quite a bummer

#

Nah it's literally just one person or two reading it

#

It should be really basic

pearl quiver
#

are you sure? because i don't know any known row limits in postgresql

native tide
#

I used the Heroku plugin

pearl quiver
#

if heroku has a limit, that's a different problem

#

if you're reading it locally, maybe you can host it locally?

native tide
#

ahh I see, thanks for explaining that. Yeah so is it easy to host it locally if you're working on the same database with multiple people?

pearl quiver
#

only if they're on your local network 😄 i don't know if your project constraints are

native tide
#

There are no constraints really. It just sounds like a fuss as your computer has to stay on the entire time. Hence I tried hosting it by Heroku

pearl quiver
#

if it's for a local project, i don't even configure a httpd. if you're using something like django or flask, you can just boot up a development server

native tide
#

But I do like your way of thinking. I might actually consider refactoring this. But my main focus now is to get more than one point in a chart at this point 😛

#

I'm using flask! A beginner, didn't know that feature existed! The more you I know 🙂

#

I'm sorry to ask but do you happen to have any experience with charts in javascript?

pearl quiver
#

not me, sorry. Javascript isn't my strength either.

native tide
#

Ahh it's ok. I really appreciate the help 🙂

#

Thanks a lot 😄

pearl quiver
#

@native tide but if you are interested in data visualization, you might consider looking at python libraries like panda

native tide
#

Yeah so the thing is, I'm using pandas for data analytics. I just save the x and y values in a CSV which I want to plot in a chart on a local website/user interface

#

Hence I need to know Javascript as well as the data comes in in real-time

pearl quiver
#

wait

#

if you already have the data from pandas, wouldn't it be easier to just pass it along?

#

instead of saving it as a CSV, save it as a JSON

#

instead of reading the CSV line by line, just pass the entire JSON

native tide
#

But JSON is significantly larger than a CSV right?

pearl quiver
#

no, that's true

#

but what i'm saying is, rather than getting python to cough up the CSV

#

just leave the file and let the httpd server the CSV directly

#

it looks like you don't even need all the fields in the CSV

native tide
#

I have no experience with that. Is it easy to use?

pearl quiver
#

you can save a nice, complete CSV, but consider also saving a shortened one with just 2 fields

#

because you only need two fields

native tide
pearl quiver
#

no, i mean, your file from before, was 50mb you said?

#

does that contain all the columns or only the two columns?

native tide
#

Yeah but that's with a lot of other data given by an API as well. Hmmm I get what you're trying to say, I just don't know how to go about it rn

#

I just want to make it work and then refactor haha
Nothing except the data scraping and data analytics works (just the user interface is not working)

pearl quiver
#
  1. flask should be able to just serve the contents of a file.
  2. the smaller that file is, the less you have to send over to the javascript, the less the javascript has to load
#

rather than processing your "big" CSV every time you need to load, make a pre-processed one saved somewhere that we can reference whenever we want. 🤔

#

that should get your file size a lot smaller

native tide
#

Exactly, so from these big CSVs, I'll make small ones with just two columns

pearl quiver
#

yes 🙂 just a couple more processing lines underneath where you save the big CSV
