I don't understand how does that relate to what I said

[thorn igloo]

man

it's better to google this stuff

you'll understand better than i can explain

a virtual environment is not really related to heroku

it's just a python thing

if you use pycharm you should realize that each project you make doesn't have the libraries you used in another project for example

it uses virtual environments to separate this

[daring isle]

Yeah in kivy ages ago

I am setting the following as my FLASK_APP environment variable

it throws the error: NameError: name 'app' is not defined

why is this the case?

[daring isle]

app = Flask(name)

[native tide]

where "name" is the name of the file?

[daring isle]

Nope

[thorn igloo]

it's __name__

[native tide]

Thats it? Damn

    const classes = useStyles();
    console.log('23')
    const [data, setData] = useState({ users: [] });
    console.log('25')
    useEffect(() => {

my code is longer but never hits log 20 in the console, anybody see anything wrong with my export?

[thorn igloo]

where are you using the User component

[daring isle]

i dont actually have a user component

this is what im trying to do

go from userlist component to a single user view

[thorn igloo]

youre exporting default User()

what is that?

isn't that a component

yes, it's a function

let me rephrase, where are you using this function

[daring isle]

im going from a tutorial who uses the singlular for their object,
blog posts , is listed as function post there

im trying to return user list instead of posts and user instead of post, im very confused atm

[thorn igloo]

that function returns html right? or jsx etc, whatever you want to call it

[thorn igloo]

.

if so,

if you're not seeing the 20 in your browser console, it basically means that component is not being mounted at all

i.e, it's not being used

[daring isle]

yeah its not, but i dont know how to get my user to show, its showing in my api , but cant figure it out in react

im trying to look online for like 2 days and cant find out the solution lol

[thorn igloo]

can you reexplain if you dont mind, i think i missed something

what are you trying to achieve exactly?

[daring isle]

I have a user model, i have that displayed as a component sucessfully.
it shows a row of cards for my users.

I want to click one and show a screen specific for that user using the pk

i've set the serialiser up in drf and the json is fine, i just have no idea how to render it in react

these are my cards

[thorn igloo]

so backend is returning json?

of the user you want to display etc

[daring isle]

yep , if i type the id into the address bar it gets the correct record

[wise osprey]

nice, seeing if there is any out there I could learn from

[thorn igloo]

right, so are you using axios by chance? or just fetch

[daring isle]

axios i believe, but im frankensteining the code as im trying to learn js

[thorn igloo]

ok, so it has a get method, i'm sure you know that by now

you can use that to fetch the data

so basically, if i understood you correctly, you're fetching a userlist and displaying it

so i see you have a route like /userlist/:id

so you can navigate to this from the /userlist route

since you have your users already, you can specify the /:id part when you navigate

[daring isle]

yeah exactly

[thorn igloo]

then you can use axios to fetch the data from the id property

react router has a useparams constructor or function i believe

[daring isle]

do you have an example? the tutorial i was following used href={'/userlist/' + user.id}>

[thorn igloo]

yeah that works i guess

[daring isle]

my code doesnt reach my useParams()

[thorn igloo]

which react-router version are you using? 5?

[daring isle]

i believe so

[daring isle]

^^^

[native tide]

Guys if I add some code, then I first use git add . git commit -m "commit message" and then push...to add code to heroku all I need is to write git push heroku?

[thorn igloo]

you can check in package.json to verify

[daring isle]

"react-router-dom": "^5.3.0",

[thorn igloo]

ok, gimme a sec

[native tide]

@thorn igloo Could you please comment what I wrote above?

[thorn igloo]

just push to your repo, and link the repo to heroku

it will automatically detect your updates

[native tide]

This worked locally but doesn't work when I upload it to Heroku

[thorn igloo]

https://codesandbox.io/s/agitated-stitch-02lc2?file=/src/App.js

ok, so i just made this showing how to use useParams

so you can apply that to your application i guess

[thorn igloo]

what does your procfile look like

[thorn igloo]

procfile

you're not supposed to invoke app.run

heroku will do the stuff for you

[native tide]

web: gunicorn PhotoMathBackend:PhotoMathBackend

[thorn igloo]

what's the name of this file?

[native tide]

PhotoMathBackend

PhotoMathBackend.py

[daring isle]

so my routes should be in aoo instead of index?

app*

[thorn igloo]

no, they can be anywhere you want

i just like putting them in app

it's just a personal preference

has nothing to do with anything

[native tide]

@thorn igloo Do you know why I get error?

[thorn igloo]

web: gunicorn PhotoMathBackend:app

try that

and again, remove app.run

[native tide]

@thorn igloo Did I connect my GitHub repo and Heroku with this line

[thorn igloo]

idk man

i use the gui on the website to connect

if you're gonna use the cli, i can't help you there

[native tide]

So all you did is use gui on website to connect and any change in your GitHub repo is automatically detected to Heroku?

[thorn igloo]

huh?

i created a repo o. GitHub

went on heroku

[daring isle]

im not sure my app code allows for this , if i try use a to="" it doesnt do anything and i dont really know where to put the params in my userlist.

Ii dont understand javascript enough, and when i try look stuff up its always different ways and layouts .

at least i understand the api side and some of the component stuff, i need to do some more reading

[thorn igloo]

started an application, then chose a GitHub repo

if i push changes heroku will automatically detect them

that simple

i didn't use the cli interface

[thorn igloo]

can't say much about your app since i don't have the source code

you understand how an anchor tag works in html right?

the link component is basically an anchor

but this one just prevents the page from reloading

[native tide]

Actually I think this is last error

[thorn igloo]

it's saying request is not defined

did you import it?

[daring isle]

mate i barely understand how this is working, im not even trying to prevent reloads atm i just want to display my data.

I'll try read up. Do you know of any decent youtube tutorials for the correct way of doing things?

[thorn igloo]

normally I'd recommend ben awad for react tutorials

but I'm not sure if his videos cover react router

just checked, he does have a tutorial

so I'd say check him out

[daring isle]

ok will do!
thanks for the help man

[thorn igloo]

sure

[native tide]

Weird, in my local version it works without importing it

@thorn igloo I imported Flask, so there should bee request

[thorn igloo]

idk man. just check your code

that you're using on heroku

[native tide]

@thorn igloo so does pip freeze detect libraries that I use in virtual envionment, libaries that I imported?

[somber garnet]

how can i display my images in my folder without having to place them in static?

[native tide]

click==8.0.3
colorama==0.4.4
Flask==2.0.2
gunicorn==20.1.0
importlib-metadata==4.10.0
itsdangerous==2.0.1
Jinja2==3.0.3
MarkupSafe==2.0.1
typing-extensions==4.0.1
Werkzeug==2.0.2
zipp==3.6.0
How so that all of that is in requirements.txt but I just installed Flask and gunicorn?

[somber garnet]

those are depencies for flask

and possibly gunicorn

dependencies

it installs those at the same time because flask needs them

[native tide]

ah I see - how so that I didn't have to install them locally?

or it was done in background?

[somber garnet]

it was done when you did pip install flask

[native tide]

I see

@somber garnet Are you familiar with running virtual environment for Python?

[native tide]

I have the following flask application

from gan import EnhanceAgent

I am trying to make a curl post request to this, how do I pass in an image to the curl request?

[inland oak]

https://medium.com/@petehouston/upload-files-with-curl-93064dcccc76

[civic dragon]

I'm new to flask and trying to do a bulk insert (for array of objects from a form) into postgres, but am running into issues. Even though I'm running in debug mode, part of my issue is being able to log the body for the post request in the console, in order to debug and figure out a plan.

[inland oak]

https://linuxize.com/post/curl-post-request/

or actually just write small python script

that uses library requests to do that

and launch it with python3 scrip_name.py

[hazy hedge]

I'm sorry but, why flask? Why not something like aiohttp or starlette?

[hazy hedge]

I also recommend to try httpx instead of cURL.

[daring isle]

In react , basic level . Are we calling api through components and delivering to index to send to root? Or calling through index and delivering to components ?

Where’s the first point of contact for the data ?

[thorn igloo]

you can make an api call wherever you need it. no need to call it in index if you don't need it there

[native tide]

hello everyone

I am developing a python app flask which is called by an another app via URL : https://host name:port/arg1=mdp &arg2=user -->hostname is my iis web server where i deployed the app. I would like to have a log per user --> when the user run the app it should normally create his own log and write in it, but unfortunately the mainthread write in all the logs of all users . I have tried : lock thread, multilogging, semaphore, socketio, calling with start-newthread -->No success 😦 Thanks for help

[raw spade]

hello, does app.route just give you a page(that has been specified)?

[raw spade]

for flask

[native tide]

it run correctlu for all users

but it write in juste one log which is the first user

i initialise the log in the upload fun with the username extrcted from thr url and i try to write in this log

but it juste create the log and write in it for all users

app.run(debug=True)
kwargs = {'host': 'ip adress web server', 'port': port, 'threaded' : True, 'use_reloader': False, 'debug': False}
flaskThread = Thread(target = app.run, kwargs = kwargs)
flaskThread.start()

[blazing dove]

I want to increment a value set in Jinja2

{% counter = 0 %}

how can I do this outside a loop?

[thorn igloo]

increment your values in the backend

[blazing dove]

I can't do that, I need to increment it in the front-end

oh... I figured out why it's not working

[daring isle]

Are you sure ?
I spent a long time trying to work this stuff into jinja , a lot of the time figured it out , but then realised it can be done backend easier most of the time

[blazing dove]

after I figured out why it wasn't working I also realized there's a simpler solution in the backend 🙂

[native tide]

Am I right that when you use flask and react, you have to use authentication tokens instead of flask sessions? This because the client who communicates with the flask API is always react and therefore the session will always be the same?

[thorn igloo]

you can use tokens or sessions

react is just a frontend tool

[inland oak]

React is compiled into pure html/CSS/js and served to each client.
Frontend exists purely at client side in user browser.
If it is not using some SSRing with node.js serving

[native tide]

React connects to my API then react is the one communicating with my server right? How can i send sessions from the client?

[thorn igloo]

if you look into flask sessions (i'm assuming it's what you're using), you'll realize that it basically sets a cookie in the browser that's sent with every request you make to the backend (provided the cookie is already created)

with react, it's still html, css and js etc, but it's a SPA

so for this, if you want to check if a user is authenticated or not using sessions, you basically have to get that info from the backend

you can just set a route in your backend to check if a user is authenticated or not and store this in a state in react

whenever you want to do something that requires authentication, you check in the backend first

that's one way of doing it

Hello, what is Django queues? and what is it used for?

[civic dragon]

I'll look into this, but will it tell me the data hitting the post route? I'm using Postman to send the request. I'm able to save a single dict, so trying to see what's going on to save an array of dicts. I'm assuming I'll have to loop through and manipulate the form data...I just don't know what it looks like / what format in Flask. Data sent from Postman looks like so:

"family": "Plasticos",

[lapis spear]

what this mean?

i have a django project from pycharm and created a django project there but now i am using vscode and just copy pasta that folder to a vscode workspace and then i try to run the project it gives me that error

do i need to reinstall django?

[dense slate]

Isn't tower an object? So tower.tower_id

[native tide]

I don't know that much about JSON but I think [] is a JSON Object and {} JSON Dictionary

[dense slate]

JSON deserializes into a python dict

So it looks like you're creating a python dict from a JSON string

[native tide]

i put in an id and it returns:

which is correct but the issue is i made a file for every single tower/monkey

[dense slate]

It made all those files but you wanted to only create one?

[native tide]

no it didn't make any files i made the files myself and im gonna store data in all of them

so if i send a GET request to the server and it says ?id=dart-monkey i want it to return everything inside the dart_monkey.json

[dense slate]

So is this your error?
TypeError: list indices must be integers or slices, not str

[native tide]

yes

[dense slate]

So how did you get the proper return if that error pops up.

[native tide]

i changed the json into only {}

but that's only for testing right now but im looking for another solution

[dense slate]

The error is saying that you are trying to do list["string"] when you need something like list[0]

so you need a dict if you want to seach by key-value pair

[native tide]

oh ok so i just remove the []

from the json file

[dense slate]

Your json should return something in {}'s

unless it is a list of objects

then it can be [{}, {}, {}, etc.]

[native tide]

im trying to achieve this:

but if i change url

[dense slate]

actually even then I think JSON needs to return {}'s.. but anyways

[rotund perch]

where are pip (Pypi) packages are stored in Django?

[native tide]

Example 1:

Example 2:

[dense slate]

I'm not 100% off the top of my head, but I think you can just import the file if it's a list. If you import it, then json.loads, you convert it into json.

[native tide]

But the problem is i have tons of json files in one directory and how is my code supposed to know which one of them to return

[dense slate]

I would structure it something like {{id: 0, data: "data"}, {id: 1, data: "data"}}, then you can select by id or whatever you want

def tower():
    tower_id = request.args.get("id")
    with open("./data/towers/" + tower_id + ".json", "r") as f:
      towers = json.load(f)
    return towers

Maybe something like that?

[native tide]

oh actually that might work

i'll try that

[dense slate]

That might be kind of insecure, I'm not sure. But if someone can write something into the URL that is m malicious, that might be a problem with this kind of code.

I don't know if that matter for you right now.

[native tide]

no that doesn't matter

right now

[dense slate]

Probably didn't install Django, like it says?

Or you didn't run inside of an active virtualenv if you are using one (which you should be).

[dense slate]

They are stored in the python site-packages folder

[rotund perch]

Thank you

[lapis spear]

do i need to add this to PATH right?

oh man, pycharm added fastAPI boilerplate option when creating a project. Is this a sign to learn it?!

[stable yew]

why does it say this

neeeeeeeeeeeed help

[edgy hinge]

Anyone can suggest me Django best book to learn in depth?

[inland oak]

Willian S. Vincent has three up to date for Django 3.2 books
Django for beginners
Django for professionals
Django for APIs
I did not read them, but I was eyeing them as the best source of going through django
Probably I should ready them already too

[edgy hinge]

So where to start? Is it sorted list of 3?

[inland oak]

The look like this, except 3.2 is written

[inland oak]

Obviously from beginner one. Not sure which one to read as second

the book about APIs tells about REST APIs

[edgy hinge]

Okay, I will decide it let me finish the first one first.

[warped aurora]

https://overiq.com/flask-101/ this is such a good flask tutorial

[edgy hinge]

@warped aurora I want to directly begin with django. Is there any problem if I begin with django ?

[warped aurora]

No that's fine

[tight ocean]

Hey guys!

I'm trying to run my flask website online instead of localhost

I have put my index.py file in the root directory

But it doesn't seem to work online

In localhost it showed the website perfectly

Anyone any idea?

[golden bone]

Show us your code repo? Where and how exactly are you running it?

[tight ocean]

public_html -> index.py

index.py returns a template

from

template/index.html

it all linked perfectly in localhost

so i just uploaded the files

but online i get a 403 error

[golden bone]

If your host is setup for static files, uploading Python there isn't going to work.

[tight ocean]

seriously?

i reserved hosting and a domain

how else do i get my flask application online

[golden bone]

Hosting where?

[tight ocean]

godaddy

[golden bone]

See if this helps: https://kanishkvarshney.medium.com/hosting-your-flask-web-application-on-godaddy-5628a60e7151

[jovial mortar]

Does anyone know the vulnerabilities with running django with the --insecure flag? (to serve static files). I thought it might be something with being able to query "/../.env" and access hidden files but I havent been able to recreate that in any tests.

[stable yew]

whats the difference between

and calling Usres() constructors directly in django

while adding users to the db

[rigid loom]

Please don't advertise here

[golden bone]

Not sure about the implications of that flag specifically, but here's a nice little article about how some vulnerabilities in Flask work: https://blog.nvisium.com/injecting-flask

[warped aurora]

when doing alembic migrations i notice some tutorials import the models to the env.py and some don't and it works fine either way, sup with that?

[strange charm]

Hello everyone, can i use slack for messaging on my website? for group chat?

[proper trench]

Did you set up the worker file for your server?

[south rivet]

Which one will take the lead to dive into (Flask or Django)?

[manic frost]

depends on what you want to dive for 🙂

[jovial mortar]

Flask is typically simpler and nicely suits smaller projects with an easy workload. django scales better if you're looking to become the next discord

But I've used both with no issues

[jovial mortar]

Yeah I was able to inject into the static files on my flask development server for another website, but I was wondering about django

[jovial mortar]

You want to message through your website?

You could always tie it into a discord webhook

[golden bone]

Ah, my bad. Have you seen this? https://stackoverflow.com/questions/31097333/why-is-serving-static-files-insecure

[warped aurora]

{% for field in form %}
{{ field.label }}
{{ field }}
How would make this loop only over the 1st two fields?

[golden bone]

Assuming I understand the question, call form[0] and form[1] directly instead of using a for loop

[wind lotus]

i learned html and css, and now ima learn JS, but should i be learning how JS works with html and css, or does it not matter and I could just flip open a book and solely learn JS (I alrdy know python fyi)

[warped aurora]

What if i wanted to loop over 30 out of 40 fields, instead of calling them directly

[golden bone]

That's a little more complicated but I think I would use enumerate with an if statement

And still use a for loop

[native tide]

Is this Django? try {{ company|slice:'4:7' }}

[golden bone]

^^^ Better idea

[native tide]

Best way I've found for searching these is "django template <thing you'd do in python"

so I did "django template slice"

[warped aurora]

oh shit jinja takes python statements

[warped aurora]

flask

[native tide]

jinja might be similar, I mostly use django

django templates are somewhat python, but often have their own syntax like you can't do form[0:30]

looks like jinja does have a |slice: though

Hi Guys!
I'm currently building my first microservice using flask and thinking about hosting it now.
Need to discuss somethings about best ways to host flask microservices with someone.
Would really appreciate the help.

[inland oak]

Just ask, don't ask to ask

[golden bone]

Not if you're doing it right. I've seen that Instagram and a lot of other major web apps run on Django

[golden bone]

#tools-and-devops is a good place to start

[inner viper]

Peace Be Upon All Of You Guys

[ivory lotus]

can I ask HTML questions here lmao

[tawdry vault]

Merry Xmas everyone. I got idea about more files in flask app like in one i have normal webpages without api sites, and in other file i will have only api sites like add something in database and so on. How should i do that ? Bsc when i use app.route('/add-item', methods=['POST']) I need to define function. But i want to call function from another file. Should I make function that will just call another function from another file ? 😄

[inland oak]

Just ask, don't ask to ask

[inland oak]

short answer yes

long answer: you should have your views (function that is routed) being short enough, handling only really simpliest workflow with input/output data

most of the action should happen in your model, packages and e.t.c. Basically where the domain specific logic is supposed to be

[ivory lotus]

Already asked stack lmao

[pine maple]

how do you suggest I should host the microservice?

I have been looking into lightsail EC2 and other stuff but not entirely sure about either'

[inland oak]

what is your microservice containing

are you working in company or making it as pet project for yourself

what are other components existing in your architecture

[inland oak]

basically, if you wish to answer the questions on your own, it would be not bad to learn a bit of System Analysis and Design

If you wish to have a simple answer...

[inland oak]

Then just get Lightsail VPS for starting

[inland oak]

Or actually I have even better answer...

it could be simpler to use a bit more simple provider

I would recommend to try a hand in Digital Ocean, Vultr, Linode.... or even Hetzner

They are all cheaper and simpler to use

AWS in my opinion is so overbloated in its interface, that without Infrastructure Provisioning (aka Infrastructure as a code) tools it looks a bit nightmare to approach 🤔

[wise osprey]

How can I run a Flask app on a different WSGI server then use Apache as a proxy on port 80?

Werkzeug worked fine but it is not recommended for production.

[native tide]

gunicorn?

Run gunicorn and bind to a port, say 8080, then have apache reverse proxy traffic to the gunicorn worker running on 8080

[wise osprey]

Have not thought about gunicorn, thanks

supports FreeBSD which is good

[native tide]

then set it up as a service and it will restart if the server goes down, that's what I usually do. Little bit of setup, but then it's so easy to deploy, restart, etc

I do it with nginx and django, but same idea

.topic

[fallow cairn]

**What tools do you use for web development?**

Suggest more topics here!

[native tide]

figma for design, flask for backend, css/html for frontend

[wise osprey]

To answer both:
FASP - FreeBSD Apache SQLite Python

FreeBSD SSH, Vim, Flask and SQLite for backend, html/css for frontend. I used Geany on Debian 11 to dev a webapp for a while before returning to using FreeBSD remotely.

[native tide]

For work: Postgres/Python/Django/GraphQL on GCP. Front end is React, but I don't work on it
Personal: Postgres/Python/Django/Flask/FastAPI depending on what I'm doing behind Nginx and usually deploy on Debian on Linode

throwback to when LAMP ruled the web, maybe?

[manic frost]

Node.js + ODBC + BSON + OWASP + DynamoDB + YAML + Erlang + XML + Puppeteer + Ecto + Cassandra + TypeScript + Semver + Teal + Haskell + ElasticSearch + Spring + PureScript + Angular + Nim + Idris + SQLite + Hack + IPC + Nginx + QBASIC + UML + IntelliJ + Scala + IELTS + Torrent + Isort + OpenSSL + NoSQL

[wise osprey]

think LAMP still runs the net, even substituting the PHP for Python

[native tide]

fair point

lot more nginx than apache now, lot more postgres than mysql

[wise osprey]

makes sense, have not used nginx much, kind of discouraging as a noob when you get 5xx errors when trying to use it for the first time

[native tide]

Yea. It takes a bit of getting used to.

[lilac sedge]

I have a question involving flask, and a website im making would that fit in here?

or would that be a different channel

[wise osprey]

yes, this one

[lilac sedge]

ok I just wanted to make sure, basically i'm trying to make a website where at the moment you can just enter something into a text field then it will print on my pycharm run console, but when you hit enter on the text field it just loads a new page saying method not allowed any ideas on how to fix this?

I can post some of the code if that would be helpful

[native tide]

Do you have your route allowing "GET" and "POST"

[lilac sedge]

from flask import Blueprint, render_template, request

auth = Blueprint('auth', name)

@auth.route('/', methods=['GET', 'POST'])
def root():
data= request.form
print(data)
return render_template("index.html", boolean=True)

yeah thats some of the code there

but even with this it's still saying method not allowed

[wise osprey]

Here is an example, if the request is POST, under else: handles it

[lilac sedge]

never mind i think i fixed it lol but thanks

[wise osprey]

np

No venv or proxy yet, would this work?

leaked the app name lol... whoops

[native tide]

That gunicorn command looks right. Might want to try 127.0.0.1 instead of 0.0.0.0 as best practice, but otherwise good.

[wise osprey]

If it binds to 127.0.0.1, it is not accessible but if it is going to be proxied, then I would use 127.0.0.1

as far as I know

[wind lotus]

CSS?

[wind lotus]

yes

[wise osprey]

something like this? https://www.w3schools.com/howto/howto_css_aspect_ratio.asp

[wind lotus]

mm, not quite

it's like this and i want the width of each red square to be equal to the height when width is 100%

nvm, ig there's no way around it, i'll just have to use whatever width the parent is as the height

[distant trout]

how do you guys check for vulnerabilities on ur web apps?

for example i am finishing up implementing my own authentication library for react/nextjs, problem is i have no idea how to test for vulnerabilities. ive checked for obvious security flaws but that's about it...

[lapis spear]

i am planning to create simple website using django
is my erd on the right track?
a user can post and comment on posts

[distant trout]

how do services like auth0 and nextauth check for vulnerabilities?

[distant trout]

this seems fine

[lapis spear]

on the react and likes feat where do i put em? on comments?

[distant trout]

id personally have a independent PostLike model for posts and have a user_id and post_id associated with it

[lapis spear]

do they need own tables? to show who liked or reacted?

[distant trout]

i implemented something like this with flask a couple years ago. this was my like model

class PostLike(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    user_id = db.Column(db.Integer, db.ForeignKey('user.id', ondelete='CASCADE'))
    post_id = db.Column(db.Integer, db.ForeignKey('post.id', ondelete='CASCADE'))

shouldnt be much different from django

my user model for reference;

class User(db.Model, UserMixin):
    id = db.Column(db.Integer, primary_key=True)
    email = db.Column(db.String(120), unique=True, nullable=False)
    username = db.Column(db.String(30), unique=True, nullable=False)
    password = db.Column(db.String(120), nullable=False)
    date_joined = db.Column(db.DateTime, nullable=False, default=datetime.utcnow)
    posts = db.relationship('Post', backref='author', lazy=True, passive_deletes=True)
    comments = db.relationship('Comment', backref='author', lazy=True, passive_deletes=True)
    likes = db.relationship('PostLike', backref='author', foreign_keys='PostLike.user_id', lazy=True, passive_deletes=True)

[lapis spear]

i added 2 tables yeah maybe it will look like this?

[distant trout]

yup seems about right. make sure to associate each of those table in your User model

[lapis spear]

nice nice thank you sir 🥳 👍

[timber pulsar]

yo

I am using Quart (Async Flask), I've set SERVER_NAME to my domain name

in order to use built-in subdomain handling

BUT i've come across an issue

when doing requests without server_name

they are refused...

anyway around this, as I'd like to keep using the fast local requests to 0.0.0.0

[serene prawn]

PostLike doesn't need it's own id though

You could use composite primary key, you wouldn't need an id and it would also provide uniqueness check

[distant trout]

Yup you're right. It was from one of my older projects and didn't really think about it much.

[jovial mortar]

thanks, that's pretty much what i was guessing. I suppose I'll use it temporarily then because i'm on a tight deadline and rewriting code does not sound fun nor quick

[distant trout]

dont think ive worked with many relational data since then

[jovial mortar]

but i'll rewrite it after we release

[unborn oyster]

I have a script that gets values from an api and uses flask to display them on a site

how would I get these to auto "refresh"

not refreshing the page but the values should refresh

[simple phoenix]

Store in json send json to page in client use javasript (arrg) some frameork like rescy

React or i forgot the others i hate client side lol

Much wow such hassle

What ever js framework your site use use it ... remember a sudo shibq has great power and responsibility not to put in too many frameworks of js for much confuse and such suffer

[thorn igloo]

you can use ajax calls to update the data every now and then

ajax calls + a setInterval function

no need to really use a framework for a simple thing

[inland oak]

Set Server name from os environ value

import is
os.environ.get('server_name','domain.com')

U will be able to override the env value for your Dev machine
python dotenv package will make it easy by allowing to write them in .env file

[inland oak]

Or set Dev values as defaults. And override them to necessary values in prod

[timber pulsar]

so I'd be able to still make a local request but with my domain name instead?

I want my bot to be able to locally request to webserver

without going through cloudflare unreasonably

[inland oak]

U will need to run local instance for Dev purposes

While having run prod instance separated

With running them with different env values

One thing should be possible to request by one domain, while other by another domain) like localhost

[timber pulsar]

sadge

[inland oak]

As a different option, just don't restrict server name

I think in some option you could accept requests from any domain

But I would hate it because of sniffers and hackers

Every IP address of any major cloud provider is constantly scanned for vulnerabilities by all sides of people

[timber pulsar]

i need subdomains

was wondering if instead I could route like in windows where you do hosts file

routing a server name to a local ip

but on linux

[inland oak]

What do u mean here

Write example of the desired end result

[inland oak]

Anyway... I think everything u wish to achieve can be achieved at the level of nginx

I think it should be able to listen to multiple domains and having different targets for each one

[golden bone]

I would attach to shell inside the container and see if your files are in the right location. I'm guessing enhance.py is missing or in the wrong place. Share your repo if you're still stuck

[native tide]

do you mind if I private message you the repo?

I did run the shell of the docker image and enhance.py is in the project

nvm i got it

[manic garnet]

hi

just here wanted to ask something

what do you prefer the most

flask vs django

[stable bear]

how do i integrate javascript?

[manic garnet]

pls reply

[haughty isle]

make a <script src="{% static 'app/index.mjs'%}" type="module"></script>

.mjs

and depends on the name of your app

are you using django?

[stable bear]

yes

[haughty isle]

yeah so you put it in app/static/app/index.mjs

or whatever you called your app?

cool

is it working?

[stable bear]

i have a variable 'now' created in views.py, and currently this is what i have in index.html. how do i update this 'now' variable using javascript?

[haughty isle]

so you'd give the element you want to update an id

[stable bear]

this is quite new to me - what is the syntax to do this?

[tiny snow]

Responsiveness (button events and such on the front-end)

[haughty isle]

if you !paste your template I can help

[tiny snow]

Client stuff like changing text according to the current time should be easy to do with JavaScript

[haughty isle]

please don't use screenshots - just use

!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.

[haughty isle]

use

```html
<head></head>

 if you want to paste inline

no space between the ```

and the html

so you'd give the elements you want to update ids:

<h1>Is it New Year?</h1>
<h1 id="is-new-year">{{ newyear|yesno:"YES,NO" }}</h1>
<h1>The date and time today is <span id="now">{{ now }}</span></h1>

@stable bear ^

what do you mean by that?

?

[stable bear]

{% load static %}
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Is it New Year's Day?</title>
    <link href = "{% static 'newyear/style.css' %}" rel = "stylesheet">
    <script src="{% static 'newyear/index.mjs'%}" type="module"></script>
</head>
<body>
<h1>Is it New Year?</h1>
{% if newyear == True %}
    <h1> YES </h1>
{% else %}
    <h1> NO </h1>
{% endif %}
<h1>The date and time today is <span id="now">{{ now }}</span></h1>

</body>
</html>

[haughty isle]

in your .mjs file you can put:

const isNewYear = document.getElementById("is-new-year");
const now = document.getElementById("now");
const sleep = async (delay) => {
  await {
    then(fn) {
      setTimeout(fn, delay);
    },
  };
};
while (true) {
  const currentTime = new Date();
  isNewYear.innerText =
    currentTime.getMonth() === 0 && currentTime.getDate() === 1 ? "YES" : "NO";
  await sleep(1000);
}
export {};

[haughty isle]

I don't see <h1 id="is-new-year">{{ newyear|yesno:"YES,NO" }}</h1> in your code?

you can add the code for updating now.innerText ?

[stable bear]

ill try it

[haughty isle]

Did it work?

[haughty isle]

Show your html?

Why do you have newyear twice?

Just delete it

flask, because it fits my needs, idk havent used django

[inland oak]

some people answer: fastapi, but I chose django. But going to try... later... eventually... fastapi

[violet dock]

Is it possible to get users who connect to the socket on flask?

[versed lotus]

fastapi is nice, all async and stuff. but I also really like sqlalchemy, and sqlalchemies async support, while present, is still kinda meh.

[warped aurora]

Using] wtforms.fields.html5 import DateField..when the form field is empty it displays like this..is there a way to hide it? or make it blank

[versed lotus]

I think that's browser dependent, but try to set a placeholder text?

[warped aurora]

doesn't seem to work

[versed lotus]

then I got no idea. it's probably not possible because browsers

[warped aurora]

Lol

[versed lotus]

the great thing with type=date is, it's different for all browsers

so I usually end up using text with a js datepicker anyway ...

[warped aurora]

hmm

[versed lotus]

maybe you can overlay a text field instead 😄

and have them hook up with each other

not sure that's gonna work in a good way though

[warped aurora]

Gonna try the js datepicker

I am having an issue with channels / django where fast real time data is being sent in intervals instead of when I call the group_send
Instead of sending the data via websocket. It tends to wait and then send ~10 messages together.

layer = get_channel_layer()
  async_to_sync(layer.group_send)("webapp",
     {"type": "dataSend","category": "imu",
      "data":[sess.id, imu_cnt, imu_time, ax, ay, az, wx, wy, wz, batt, rssi]})

async def dataSend(self, event):
     send_json = json.dumps({"type":"dataSend","category":event["category"], 
                             "data": event["data"]
                            })
     await self.send(text_data=send_json)

(the group_send is being called ~every 15ms) but instead of sending that "Data" in a self.send. It waits and sends ~ 10 together to my frontend

[haughty isle]

Don't use threads like that with asyncio, use await asyncio.to_thread(sync_fn)

yeah it is still the same problem (

I use memcached to store whether I am connected to devices or streaming the datato a queue

I need to keep those memcaches alive while the user still has browser open / websocket is open

I can remove that thread for now if you think that is causing my issue

cache.get does blocking IO?

[vast rune]

hmm i don't think so

if I understand your quesion correctly... but I turned all of that off and I still have this delay

same

the websocket keeps sending the group of messages every 1-2 seconds

plus cache.get only occurs on the connection. That all works well.. My issue is with the

Hi Im testing some Scrapy commands for my project and although I've been looking for some contexts in which the command "fetch" can be used I still don't know if I should use this command and selenium (if I can even incorporate it to scrapy) on these approximately two hundred web pages to get all the necessary elements, click buttons and basically interact with JavaScript. I also had some questions, Im willing to listen if anyone knows something which you could consider useful:
Should I create a new Spider for every URL even if it's on the same webpage? Do I have to create a Spider for every webpage? Am I able to incorporate Selenium to my Scrapy project to click buttons? Is it the best option or the only one?

Hey guys, do I need to setup a cookie consent if I didn't set any cookies on my website?

[inland oak]

good question. I would like to have an answer for that too. I am in the same position 😆

[weary spear]

As far I've checked in 2 browsers - Chrome and Firefox, there's no cookies (In the developer options)

[inland oak]

https://www.iubenda.com/en/help/5525-cookies-gdpr-requirements

it says no

but

Do we need to ask for usage of localStorage? 🤔

[weary spear]

Why everything is so complicated right now?

[inland oak]

The cookie law is not actually about cookies (and its not actually called the cookie law). Its about tracking users, storing and sharing the information with third parties. Cookies are just the most popular method to track users.

If you don't want to show the "cookie warning" then just don't track the users beyond the session and don't share traffic data with third parties.

https://softwareengineering.stackexchange.com/questions/290566/is-localstorage-under-the-cookie-law

If you don't use cookies at all then it would be a huge misinformation to warn your visitors about using cookies. It may even be useful to explicitly state that you don't use cookies. Remember that warnings about cookies are for people who want to avoid cookies so they should know when they finally get to a rare website that doesn't use them. But you may still need to warn about other things, like local storage. Just don't call it cookies if those are not cookies because it would be a misinformation that can even be against the law.

According to The EU Cookie Law website:

Is is just cookies?

No - The law also affects anything that acts like a cookie, for example:

Flash Cookies
HTML5 Local Storage
The ICO has said that it isn't good enough to just re-implement the tracking some other way outside of cookie storage.

This is just my interpretation, and could be wrong, but as i understand it, if you use local storage in a way that doesn't allow you to identify individual users, it doesn't apply, so for example using local storage to store user preferences wouldn't require notification, but using it to store a session id that then automatically gets sent back to the server would. – 
Jules
 Sep 2 '15 at 20:00

@Jules: You are correct. You can also use cookies without having to notify the user. It is not a question of any specific tracking method, but rather if you store the traffic data or share it with third parties. – 
JacquesB
 Sep 2 '15 at 20:41

[tawdry chasm]

Anyone know of any https proxy server libraries/examples that are relatively easy to setup, and has the functionality of switching a domain with another?

[inland oak]

I think as long as we don't keep User ID in cookies or local storage, or any other way to idenfity the user machine, we can avoid warning about cookies

or even better we can warn that we don't use cookies!

[weary spear]

Okay, so I will skip that part, will DM you once I will be fined by the GDPR guys 😛

[inland oak]

lets test who would be earlier fined then ;b

[weary spear]

Deal!

[simple phoenix]

Yeah interesting but it is necessary since cookies arent the only means of tracking. Unfortunate thou they should have called it online data privacy law . Lawyers there at least covered all bases but stuck with cookie lol

My hosting provider has a default route domain.com/phpmyadmin - can I overwrite it with flask somehow?

@app.route('/phpmyadmin')
and then redirect to 404 is not working

[manic frost]

What hosting provider is that? It shouldn't be like that. Ideally they should just provide you with a blank VPS and don't touch it, and don't install anything on it

[weary spear]

cyberfolks.pl - technical support told me it's not possible to change that and all I can do is just have a strong password...

[inland oak]

ridiculous. how about to change hosting provider 🙂

or finding if they provide VPSes to host stuff

[inland oak]

i have no idea in which way your applicaiton is hosted

apache web server in python mod perhaps

scan your hosted app to find out

or better host in VPS

using hosting like that is perversion

[weary spear]

a standard cPanel hosting so most likely it's apache, but how can I check it?

find any tool or online service to check headers of your web site

when you populate a wtform with an obj it just does it sequentially?

[haughty isle]

what do you mean by that?

[warped aurora]

if i do form = form(obj=model).. the form fields are just populated in the order the columns for the table are?

[haughty isle]

which table?

why are you re-assigning form?

[warped aurora]

I'm pre populating the form data from a table

form = test_form(obj=table_data)

[haughty isle]

does it work?

[warped aurora]

Ye it does, so my question was the order in which it populates the form fields is simply the order of the table data?

[hard schooner]

Hello guys I am new with cloud flare, I have recently added my domain in cloud flare, problem is with ssl, SLL is working on main domain properly but not with sub-domain www how can i add ssl on "www". My DNS record of www is targeted towards my site.

[haughty isle]

the order of which fields?

[haughty isle]

are you not proxying www through cloudflare?

[hard schooner]

yes

[haughty isle]

right you'll need to get a cert on the machine that's terminating TLS then

or proxy it through cloudflare

[hard schooner]

I have proxied every record using cloud flare

[haughty isle]

why not proxy www then?

[hard schooner]

including www, changed recently to check if it workds

[haughty isle]

does it work?

[hard schooner]

nope

[haughty isle]

how long was the DNS cache time?

[hard schooner]

??

[haughty isle]

there's a number next to every dns record

you have to wait that amount of time each time you change something

[hard schooner]

I think it is 1min because i have changed dns records recently and it only took 1 min to show effects.

[haughty isle]

ok so it works now?

[hard schooner]

nope

does creating a origin ssl certificate and adding in my hosting cpanel and turning off sll from cloud flare will help?

Im using fastAPI for my application's backend but have no experience building frontend user interfaces, What is the industry standard to create a UI that will make the calls to the API backend?

[slender isle]

The industry standard is JavaScript or TypeScript alongside a framework of some kind. The most common frameworks are probably: ReactJS, Angular (a bit outdated at this point), or Vue. Svelte is also growing quite quickly and seems very nice to use

[near ridge]

Did the example ones I found help?

[rigid laurel]

yeah, one of them was pretty helpful

[near ridge]

Awesome

[rigid laurel]

although they also kinda confirmed my suspicion that there's no good way to do this thing that the framework isn't meant to do

[near ridge]

Sounds about right. So why are they binding your hands with this?

[rigid laurel]

so what happened was. My boss said "We need this thing". I said <thing> is easy, I could crack it out in a day. So I made it in literally 20m using Flask and HTMX, but I was too lazy to add any CSS. I showed it to him with no CSS - and his response was "yeah, that's pretty cool, it does what we need, but lets just do it in Dash because it's a lot easier to make things pretty in Dash"

and then <thing> has grown to have a lot more features tacked onto it, including a database and authorization business logic and all sorts that just belongs in Flask/or some other web framework

[near ridge]

Is what you do heavily data science related? I'm trying to figure out why he would insist on Dash

[rigid laurel]

moral of the story: always add styles before showing anything to anyone

[near ridge]

True

[rigid laurel]

yeah - I'm on a data science team, what I'm actually building is a SPARQL query console which makes data scientists lives easier

think like an SQL console in the browser, with things like syntax highlighting and downloading your results as CSV and other things that are helpful

[near ridge]

That's a really solid concept, I like it

NP - there's a lot to front end development. If your interactivity is somewhat limited, then you don't necessarily need a whole framework, you could just stick with some vanilla JS for updating small parts of your website - the whole idea of JS (whether vanilla or in the form of a framework) talking to a backend is called "AJAX", which really just means requests over the web which are JSON instead of HTML

[golden bone]

Did you Google it? Multiple relevant answers on StackExchange come right up for me. Try those and see if you encounter a specific problem

Anyone here have experience with Django / crispy-bootstrap 5.?
I'm trying to upgrade from BS3 (using django-crispy-forms) to BS5. Since crispy-forms only has templates for BS3 and BS4, that second library (crispy-bootstrap5) was created for BS5.
My issue is that even though I setup everything as the Github readme suggests, I still constantly get a template doesn't exist: bootstrap5/whole_uni_form.html error. Its like it is not seeing the crispy-bootstrap5 template pack.

use eslint.

First thing you should do in a new project. npm i eslint

[random oar]

how do you bypass a website that detects and blocks proxy users? mention me when you reply thanks

[frank shoal]

Use a different proxy.

most websites have a denylist of proxy hosts. If the request comes from an IP known to be a proxy provider, it blocks it.

[random oar]

i thought it checks the header

even though my proxy is an elite proxy, it will raise a semaphore timed out error

[frank shoal]

proxies typically pass the headers through.

Unless it's a reverse proxy

[random oar]

ill try using couple new proxies

[frank shoal]

You might need to use your own or get an obscure paid one.

[random oar]

I used another proxy server, it works for other low security websites, but for this website it now shows a different error message='invalid constant string', url=URL('http://119.190.187.194:8060') seems like its working but not completely

with the old proxy it shows the remote computer refused to connect

i am using aiohttp to request btw

[rotund perch]

how do I restrict a URL that no one can access unless paid or checked out (Such as can not access a course except if paid for it)

[serene prawn]

What framework you're using?
You're probably looking for attribute based access control (abac)
As a simple example - imagine you have a User and Post

@dataclasses.dataclass
class User:
    id: int
    username: str

@dataclasses.dataclass
class Post:
    id: int
    user_id: int
    title: str

All users might have read rights to posts, but only user with user.id == post.user_id would be able to modify it.

[rotund perch]

I am using Django, but what I understood from u is I can make for example a boolean of (paid =False) in the user field and whenever its checked out make the boolean True and any one with the (paid = True) can access the URL is that right?

[serene prawn]

You'd need a "secondary" table that would create a many-to-many relationship between users and courses, this can be done using many-to-many relationship
https://docs.djangoproject.com/en/3.2/topics/db/examples/many_to_many/
If you need to store information about paid course e.g. when user paid for the course, price at the time, e t.c. you'd need to create that table yourself

So you probably need a schema like this if you want to have some additional data in your relationship between courses and users:

class User:
    id: int
    username: str

class Course:
    id: int
    title: str

class PaidCourse:
    user_id: int
    course_id: int
    paid_at: datetime

[rotund perch]

oh okay. Thanks!

[serene prawn]

And making simple boolean flag on user model won't work - you need to distinguish between paid and not paid courses for a specific user

[rotund perch]

Yes, I got that

scroll animations are possible with flask ?

:/

[inland oak]

depends on what is your definition of scroll animation

[distant panther]

the fade in and fade out animations

[inland oak]

when they are supposed to start and end

[distant panther]

fade in and out animations are possible with flask?

[inland oak]

when they are supposed to be triggered for start and end.

anyway, lets say yes, they are possible

[distant panther]

how i can make them with python flask ?

[inland oak]

I could recommend this book as an answer

[native tide]

any ideas on how i can make these look better? i've done the 'art' behind them but i just dont know what to do with the cards

wrong channel sorry

[knotty robin]

I am too noob in web development but can someone actually tell me if there's a way I can convert my website to a secured connection on https://nc.me/

[inland oak]

sure. why not. ¯_(ツ)_/¯
https://www.youtube.com/watch?v=c6rP-YP4c5I

1. get domain, (point it at your IP address of the server)
2. setup ssl certificates, (buy them or get for free from https://certbot.eff.org/)
3. attach certificates to web server,
4. ???
5. PROFFIT!

[plucky cape]

I'm using flask and MySQL to make a website where the login page redirects you to a specific page depending on whether you are an admin of the page or not. for this I've made a specific admin field in the table, where if its value is "yes" then the login page should redirect to an admin page which has a few more things compared to a normal users page.

The problem arises with the sessions, and I'm not sure how I'm supposed to go ahead with trying to fix the code so that it redirects to 2 different pages.

this is for the normal login:-

@app.route('/login', methods=['GET', 'POST'])
def login():
    msg = ''
    if request.method == 'POST' and 'username' in request.form and 'password' in request.form:
        username = request.form['username']
        password = request.form['password']
        adm = request.form['adm']
        cursor = mysql.connection.cursor(MySQLdb.cursors.DictCursor)
        cursor.execute('SELECT * FROM accounts WHERE username = %s AND password = %s AND adm= null', (username, password,adm,))
        account = cursor.fetchone()
        if account:
            session['loggedin'] = True
            session['id'] = account['id']
            session['username'] = account['username']
            return redirect(url_for('home'))
        else:
            msg = 'Incorrect username/password!'
    return render_template('login.html', msg=msg)

this is the admin login :```py
@app.route('/admin_login',methods=['GET','POST'])
def admin_login():
msg = ''
if request.method == 'POST' and 'username' in request.form and 'password' in request.form and 'adm' in request.form:
username1 = request.form['username']
password1 = request.form['password']
adm = request.form['adm']
cursor = mysql.connection.cursor(MySQLdb.cursors.DictCursor)
cursor.execute('SELECT * FROM accounts WHERE username = %s AND password = %s AND adm = yes', (username1, password1,adm,))
account2 = cursor.fetchone()
if account2:
if adm=="yes":
session['loggedin2'] = True
session['id'] = account2['id']
session['username'] = account2['username']
return redirect(url_for('adminhome'))
else:
return redirect(url_for('home'))
else:
msg = 'Incorrect username/password!'
return render_template('admin_login.html', msg=msg)

this is the error im getting with this code

what exactly is wrong here and how do i fix it?

[knotty robin]

3rd how??

Plus I wonder if namecheap already gives ssl certificates

[inland oak]

i use namecheap and can say that it offers them for a price
https://www.namecheap.com/security/ssl-certificates/

certificates from namecheap last only one year, so a bit pointless to buy certificates longer than that from namecheap

certbot reapplies itself infinity times for free every 3 months if I remember

[knotty robin]

Uhh I have github student plan if that changed anything

[inland oak]

no idea. I did not use it with student rights

[knotty robin]

How can I check if I got the certificate??

[inland oak]

open your client area and go to SSL Certificates section

read the docs about student program

[knotty robin]

Ah alr lemme see

[inland oak]

check if you can buy certs for free when your student account is opened

[knotty robin]

Guess I have it

[inland oak]

👍

[knotty robin]

But how to use it broo??

[inland oak]

try and see in your client area

[knotty robin]

Nvm what is CSR??

It asked for CSR when I tried to activate the certificate

[inland oak]

I don't remember how it is pronounced
but you generate with openssl tool key and csr

and then submit csr to namecheap to convert it to other certificate parts

then you combine received new certificate parts into proper certificates

and attach them to web server

[vague yacht]

in the normal login, you try to access request.form['adm'] but the 'adm' key doesn't seem to exist in request.form

[knotty robin]

How do I compete the DCV method....

[inland oak]

the process of verificating domain?

[knotty robin]

Yeah....

The domain is clearly linked to my account

But it still asks for it

[plucky cape]

but in the table the adm thing does exist?

[inland oak]

I find the easiest way to verify through hosting the file at web server

it is just easy to check method which is hard to mess up

that works quite fast to verify

I just rent VPS for small time for that, raising in docker nginx there and putting the asked files

and changing my domain to point to ip address of the VPS

[vague yacht]

the db is not relevant here, request is the incoming request from the client and request.form is missing the key

[plucky cape]

how do i fix that?

[knotty robin]

My webpage is hosted at GitHub pages

[inland oak]

then why the hell do you need certificates

[knotty robin]

Idk....

[inland oak]

Github auto gives you domain / https and certificates

[knotty robin]

NameCheap just shows insecure website

[inland oak]

if you wish your other domain to lead to it, just make CNAME record, that leads to your github page

[knotty robin]

My CNAME record already leads to my github page

Idk if I am acting dumb rn cuz I really dk a shit bout this

[inland oak]

https://dd84ai.github.io/darkbot/
I have github pages web site, it works splendidly

everything is secure

[knotty robin]

Same with me

But I wanted my domain to point at my github page

[inland oak]

perhaps certificate should include source domain as well 🤔

in that case you can resolve the issue by...

....hmm

[knotty robin]

By?

[inland oak]

thinking

how well would work reverse proxy in this case

[knotty robin]

What do I think?

[inland oak]

not sure for sure

[knotty robin]

Man I am confused......

[plucky cape]

wait i fixed the error

but now, its not redirecting to anything at all

it just shows the login page

[vague yacht]

depends on what you want it to do
if you dont want it to enter the if at all, you can add and 'adm' in request.form: in the condition like in the admin login

if you want it to enter the if and want to give it a default value like False if 'adm' is missing, you can do request.form.get('adm', False)

[plucky cape]

for the normal login, the adm value is supposed to be null because the adm thing is supposed to let them open the other site

should i put the second thing?

@app.route('/login', methods=['GET', 'POST'])
def login():
    msg = ''
    if request.method == 'POST' and 'username' in request.form and 'password' and 'adm' in request.form:
        username = request.form['username']
        password = request.form['password']
        adm = request.form['adm']
        cursor = mysql.connection.cursor(MySQLdb.cursors.DictCursor)
        cursor.execute('SELECT * FROM accounts WHERE username = %s AND password = %s AND adm= null', (username, password,adm,))
        account = cursor.fetchone()
        if account:
            session['loggedin'] = True
            session['id'] = account['id']
            session['username'] = account['username']
            return redirect(url_for('home'))
        else:
            msg = 'Incorrect username/password!'
    return render_template('login.html', msg=msg)

this is the current code

[vague yacht]

actually, why are you creating the adm variable here at all? you don't use it

[plucky cape]

its not required?

[vague yacht]

adm=null is constant in the query

[plucky cape]

i just wanted to make it null

[vague yacht]

yes, it is null in the query

[plucky cape]

if i dont enter it its null right?

[vague yacht]

('SELECT * FROM accounts WHERE username = %s AND password = %s AND adm=null', (username, password,adm,))

there's only two %s in the query (for the username and password) adm is not a variable, its always null

[plucky cape]

so if i remove it from both the cursor execute and the request form thing it should work as null right?

[vague yacht]

you need to keep the AND adm=null in the query as it is

you do not need the adm variable that you create

[plucky cape]

that i hav kept

[vague yacht]

yeah

you can yeet the variable

[plucky cape]

hmmm

@app.route('/admin_login',methods=['GET','POST'])
def admin_login():
    msg = ''
    if request.method == 'POST' and 'username' in request.form and 'password' in request.form and 'adm' in request.form:
        username1 = request.form['username']
        password1 = request.form['password']
        adm1 = request.form['adm']
        cursor = mysql.connection.cursor(MySQLdb.cursors.DictCursor)
        cursor.execute('SELECT * FROM accounts WHERE username = %s AND password = %s AND adm = yes', (username1, password1,adm1,))
        account2 = cursor.fetchone()
        if account2:
            session['loggedin2'] = True
            session['id'] = account2['id']
            session['username'] = account2['username']
            return redirect(url_for('adminhome'))
        else:
            msg = 'Incorrect username/password!'
    return render_template('admin_login.html', msg=msg)

how do i fix the admin login now?

[vague yacht]

you get an error here?

[plucky cape]

no it just doesnt work 😭

[vague yacht]

i'm confused about what you're trying to do
specifically the adm variable

[plucky cape]

nono see

like in the site im making

there are 2 places you can get redirected to

one normal site, and one admin site

the admin site has access to some stuff that the normal one doesnt have

so when you register you have to manually change the adm value to assign the admin status to a user

what im trying to do with this

is try to make it so that if you login with an account which has the admin status

it redirects to the other site

and not the normal one

[vague yacht]

okay yeah i'm gonna have to step back now; this is beyond my webdev knowledge lol

[plucky cape]

thanks for trying tho lmao

do you know of an effective way to solve this issue?

ok now a new issue, even though i enter the right details into the login page, it doesnt redirect to the other thing and still just stays on the login page itself

adm is the one thats supposed to check that

char

yeah because thats the value ive assigned to it

not really

not anymore

its just redirecting me to the login page now

which im already on?

where would i print it

in the terminal or on the site?

gimme a sec

wait its not printing

wdym?

how do i fix that

this is what i get

still shows the same error

which one?

import mysql.connector

mycon=mysql.connector.connect(host='localhost',user='root',database='project',password='--------')

cur=mycon.cursor()
cur.execute('SELECT * FROM accounts WHERE username = %s AND password = %s AND adm =`yes` ')
data = cur.fetchone()
print(data)

uhuh

OH

so i just have to remove them for now right?

hmm

import mysql.connector

mycon=mysql.connector.connect(host='localhost',user='root',database='project',password='password')

cur=mycon.cursor()
cur.execute('SELECT * FROM accounts WHERE username = `hi` AND password = `hu` AND adm =`yes` ')
data = cur.fetchone()
print(data)

does it have to do with the version of mysql im using?

yeah this is working

instead of single quotes?

lemme test that gimme a sec

this is what i get on the website

and this on terminal

i did

[scenic galleon]

i made a code seperaly and merged (copy pasted) the html js and scripts with the other main file now i get

Uncaught TypeError: Cannot read properties of null (reading 'find')

The code (this is the line console is pointing)

 var confirmBox = $("#confirm"); //this is triggered by a onclient event of a button
 confirmBox.find(".message").text(msg);

#confirm is

<div id="confirm">
      <div class="message"></div>
      <input type="text" id="link_url" class="link_url" readonly/>
      <div class="buttons_popup_share">
        <button class="copy">Copy</button>
        <button class="share">Share!</button>
      </div>
</div>

remember it works separately in another file without the other code for the main site (i have the same jquery for both files (http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js))

ping if you reply

[plucky cape]

should i remove the admin login thing and just try doing it from the login page?

or will that make it more complicated

wdym?

how would i alter the code

something like if adm == 'yes' redirect to admin if not redirect to normal?

it works

yeah that is what i want

wait no

i want it so that the admin can do normal stuff + admin stuff

which is there on my page

gimme a sec

now just try and run it?

wait the form doesnt take any input

for admin

you have to manually change it in the database

hmmmmmm

it still is just making it stay on the log in page

but oh well its printing the thing now

but its still showing incorrect password rn

for some reason

so remove the request form and then in the last line where im taking the adm1 thing?

username1 and password1 arent defined in this one

oh this is the for the admin login thing?

nope, its still saying incorrect

[manic crane]

anyone using DRF know how to fix this ? {
"detail": "Token is expired, login again"
}

[plucky cape]

aaaaaaaa

wait after the request.form thing?

its not being printed

what exactly is wrong with the form?

@app.route('/register', methods=['POST','GET'])
def register():
    # Output message if something goes wrong...
    msg = ''
    # Check if "username", "password" and "email" POST requests exist (user submitted form)
    if request.method == 'POST' and 'username' in request.form and 'password' in request.form and 'email' and 'adm' in request.form:
        # Create variables for easy access
        username = request.form['username']
        password = request.form['password']
        email = request.form['email']
        adm = request.form['adm']
                # Check if account exists using MySQL
        cursor = mysql.connection.cursor(MySQLdb.cursors.DictCursor)
        cursor.execute('SELECT * FROM accounts WHERE username = %s', (username,))
        account = cursor.fetchone()
        # If account exists show error and validation checks
        if account:
            msg = 'Account already exists!'
        elif not re.match(r'[^@]+@[^@]+\.[^@]+', email):
            msg = 'Invalid email address!'
        elif not re.match(r'[A-Za-z0-9]+', username):
            msg = 'Username must contain only characters and numbers!'
        elif not username or not password or not email:
            msg = 'Please fill out the form!'
        else:
            # Account doesnt exists and the form data is valid, now insert new account into accounts table
            cursor.execute('INSERT INTO accounts VALUES (NULL, %s, %s, %s, NULL)', (username, password, email,adm))
            mysql.connection.commit()
            msg = 'You have successfully registered!'
    elif request.method == 'POST':
        # Form is empty... (no POST data)
        msg = 'Please fill out the form!'
    # Show registration form with message (if any)
    return render_template('register.html')

this is my register code

if thats whats causing any problem
