[native tide]

just for reference, my urls.py is configured like this @frank shoal

[dusk portal]

have anyone used lib called
django-private-chat

[frank shoal]

Do you know what a long is?

a long (generally) is a 64 bit integer.

it is not a long string.

[native tide]

no in this case i declared the model myself

the name is kinda confusing lol

[frank shoal]

oh, long is the name

[native tide]

yeah the long version of the url

[frank shoal]

You should still consider using a query parameter instead.

[native tide]

but then how can i retrieve it? i mean how can i pass it to the backend?

sorry if this sounds stupid btw, but i can't find anything online about this

[frank shoal]

query is always passed to the backend. It's usually in a request variable

https://django-ninja.rest-framework.com/tutorial/query-params/

I guess something like this. ```py
def do_something(request):
print(request.GET.get('url', ''))

[native tide]

ok, i'm gonna try to wrap my head around this

thanks a lot

[azure shard]

hello, im trying to learn flask and read this on the documentation

$ export FLASK_APP=flaskr
$ export FLASK_ENV=development
$ flask run

will this command set anything permenent to my system? i don't know much about environment variables and i'll proly be deleting this flask app and creating new ones while learning and don't want it to leave any uneeded things on my pc

[native tide]

Should url encoding be done server or client side?

[surreal portal]

Anybody here using selenium and having a list of options you can pass in ChromeDriver? I've been checking the source code and so far I'm not seeing any enumeration.

[golden bone]

Those changes will be reset on reboot. They also won't impact anything but Flask

[golden bone]

In theory Options can be empty if you want but often you do need --headless and/or --no-sandbox depending on the environment

[surreal portal]

--no-sandbox removes extensions right?

The ones I'm attempted to use are --headless and --incognito

[golden bone]

It's a bit lower level than that I guess https://www.google.com/googlebooks/chrome/med_28.html

[surreal portal]

Ok so iirc it protects from malicious content. I'm using Selenium for webscraping so it's best if I keep both flags on?

[left tangle]

Thank you!

Ayo fellas, wondering if it's possible to unescape html characters? Men&s;s converts to Men's on the website i'm parsing. html.unescape doesn't seem to conver it

I'm trying to merge two django apps into one, I'm setting db_name in Meta to avoid moving tables, how would I merge the migrations from the now deleted app into the combined app?

[nimble thorn]

heyo, short question i want to use python the requests lib to download a csv file from a website, the thing is, the download is triggered if a certain html element is clicked and prompts e.g. firefox dialog popup to save the file on disk, is this possible to automate with this python lib ?

[scenic furnace]

It is, but a lot of people don't seem to know this and I myself did not. I figured it would be useful for people to know.

[native tide]

well its kind of like

having multiple youtube videos

opened

in the same browser

its kind of obvious the browser wont ask you to re-login

for every individual tab

[golden bone]

If it's JavaScript you probably need Selenium but if it's just a simple request then requests should work. You might need to use developer tools to figure it out. Or show us the link if you can

[thin dome]

in django i am passing a list to my template

list = [{'name':...,'url':...}, ...]```
so i wrote {% for i in list %}

can we use this

{{ i['name'] }}

[indigo kettle]

yes but you access it with i.name

[thin dome]

oh ok thanks :)

[thin dome]

do we have to load anything in template to use {% set a = ... %}

Question, I'm not immediately doing web dev yet (I tend to ask questions ahead of time) but what's the difference between Cypress and Selenium

As far as I know, they're used for larger scale website testing in comparison to something like Jest but that's about it

[inland oak]

Jest is for suiting for Unit and Integrations tests

Learn Jest first

Unit and Integration tests are giving more... quality/proffit for time investment into them

Unit tests are the fastest, precise, pointing to exact error location usually

Integration tests are showing how the service works in integration with other services

You can even write in some frameworks End to End tests too in them

with a help of framework additional libraries

Cypress and Selenium implement the most expensive tests that make at the same time the biggest impact, while being the longest to run, but their point that they make THE most identical last testing to production running. They can see what any other tests can't.

But they are a hell of expensive (in terms of time wasted for implementation, time running and maintanance) and not really even written in small projects usually

Unit and Integration tests are the most important and should be done first

[smoky forum]

Is there a way to get an app in a app store without paying?

[harsh helm]

So I should only use Cypress or Selenium for larger scale projects, and even then prefer Jest if possible?

[inland oak]

U should use always Jest type of testing for all types of projects
and in projects that require a special quality / large projects and e.t.c. to add Cypress/Selenium testing in addition

Here is a regular propoprtion of amount of tests in a project to have quality testing

not really the real proportion is shown here, but you get the idea

[harsh helm]

Ah, thanks for giving me advice

[cerulean badge]

how do i generate unique group names for consumers for individual chess games? i could have used pk but i don't want to store the game in db

[cerulean badge]

django

[twilit needle]

That's not entirely true. Jest is a js testing library. You can certainly use it to perform integration tests too, though it's mostly used for unit tests with frontend libraries like react or angular.

The line between using jest and cypress can get a bit blurry when testing- do I unit test my ui component or just let cypress test it?

The difference is libraries like cypress run tests in the browser. So this is a good place to run tests from the perspective of the user- testing entire auth flows and what not

how can I run and monitor a long running background job in flask?

Hi
I want to deploy a flask application with gunicorn on heroku. Should I keep app.run() in the app.py file or is not required because it says do not use run() in production env.

[inland oak]

When u use gunicorn, app.run will be not used

[west skiff]

Oh that means it won't cause problem if I just keep it there?

[sharp dove]

does anyone have any ideas why I am unable to extract data from a simple form I made

The first picture is python file in relation to flask
The Second picture is html file with a form

[west skiff]

I think its because you've written methods in the form tag instead of method

[sharp dove]

oh shit

right

wait let me try change that

im getting this error still:

[west skiff]

which line is this error for? i can't tell if its for those u sent above

[whole garnet]

Why did u put slashes at the end of tags

[sharp dove]

im mac

thats how it is lol

[whole garnet]

Ohh kk

You run npm run build and it would place everything you need into build directory

[cerulean badge]

(django) in a consumer, does it stack the messages sent from client to server and then call recieve method for them? and does sending message in group with self.channel_layer.group_send calls the method of type use the same stack? I am asking cause, if a client sends a move repetedly then this code will just crash, since it will allow both or all the legal move they try to play cause it updates the self.board when the method of type is called after sending a msg with self.channel_layer.group_send?

def move_if_legal(self, san):
        if self.board.turn != self.client_colour:
            return

        try:
            move = board.parse_san(san)
        except ValueError:
            return

        if not move:  # null move
            return

        async_to_sync(self.channel_layer.group_send)(
            f"game_{self.game_uuid}",
            {
                "type": "moved",
                "san": san,
                "colour": self.client_colour,
                "time": timezone.now().isoformat(),
            },
        )

    def moved(self, event):
        if event["colour"]:
            self.update_white_timer(dateparse.parse_datetime(event["time"]))
            deadline = self.get_black_deadline().isoformat()
        else:
            self.update_black_timer(dateparse.parse_datetime(event["time"]))
            deadline = self.get_white_deadline().isoformat()

[cerulean badge]

I have posted it as concise and precise as I can, pls ask what part you did not understand, your reply seems like you do not even try to help, and if that is true then you should just not ask, not trying to be rude if that seems like sorry.

[cerulean badge]

In short should i do it like this instead

        if not move:  # null move
            return
        
        self.board.push(move)
        async_to_sync(self.channel_layer.group_send)(
            f"game_{self.game_uuid}",
            {
                "type": "moved",
                "san": san,

                "time": timezone.now().isoformat(),

        if event["colour"]:
            self.update_white_timer(dateparse.parse_datetime(event["time"]))

        else:
            self.update_black_timer(dateparse.parse_datetime(event["time"]))
            deadline = self.get_white_deadline().isoformat()

        text_data = {
            "command": "moved",
            "san": event["san"],
            "colour": event["colour"],
            "deadline": deadline,
        }
        self.send(text_data=json.dumps(text_data))

        if event["colour"] == self.client_colour:

Well... it is telling you what's wrong. find_elements_by_* commands are deprecated, and you should be usingfind_elements() instead

"deprecated" means that for whatever reason they will be removed in some near future

hey

[languid raptor]

I have an accounting API which I want to access. I have credentials, and made a basic request of an endpoint. All good.

Now I need to learn the syntax for URL requests, how to "link" endpoints, basic query and post activities for APIs.

Anyone care to share recommended resources to get up to speed. Books, video series, Udemy, Edx, etc.
??

[serene prawn]

Hm, you mean you want to just access that API from python?

[golden bone]

The documentation for the specific API is going to be your most important resource. Making simple API calls from Python is pretty simple, just use requests to get or post

[serene prawn]

I'd recommend httpx over requests

[languid raptor]

I'd rather have an ORM

[serene prawn]

Sorry, what it has to do with ORM?

[languid raptor]

Object Relational Mapper. Meaning I'd rather deal with objects than JSON, URLs, etc

[serene prawn]

ORMs usually work with databases, API is not a database

You can convert your json responses to objects

[languid raptor]

Its simple to make the call, but the data I'm querying is a complex POS system. There are interrelated end points. To get the full picture of the data as it's represented in the POS system in store, you're actually "linking" is the term they use, multiple data sources. All very compled and beyond just calling one endpoint

[languid raptor]

Thats all good stuff. So, do you have a recommendation for how you learned this?

[serene prawn]

What do you mean? 🤔

[languid raptor]

Sorry if I was unclear. I;m asking for resources for learning about APIs

[serene prawn]

I don't really remember 😅

[languid raptor]

Fair

[serene prawn]

If you need to query multiple endpoints to get a full object you need you really have two choices:

1. Do it manually
2. Create a proxying api, for example, using a graphql library/framework

It would fetch data from that api for you (you have to code it ofc), but for example:

{
  getUser(id: 42) {  # Could issue call to api/users/42
    username,
    posts  # Could issue call to api/users/42/posts
  }
}

It all depends on api you're working with though

[languid raptor]

Here is the swagger 'docs'
https://api.mobilebytes.com/

sales is composed of tickets which are composed of menu items

[languid raptor]

Also, here is an issue I was struggling with which I hope learning more about APIs from a book or other educational resource would clarify:

"...their JWT endpoint expects username and password as body field instead of basic auth that the python [module request] generates" [my emphasis]

I struggled with that for three days because I didn't recognize the difference.

You probably don't need to delete the models. I would just delete the url path to the admin site if you don't want that to be accessible at all

thx for the reply and sorry for my late reply, um the thing is the firefox download dialog gets triggered if js code is executed (which is happing upon clicking on <a> tag element)

https://app.luis.steiermark.at/luft2/suche.php?station1=139&station2=&komponente1=125&station3=&station4=&komponente2=&von_tag=1&von_monat=1&von_jahr=2022&mittelwert=1&bis_tag=21&bis_monat=1&bis_jahr=2022

this is the website in question

i was thinking that i might need selenium, however i thought maybe python requests lib could handle this aswell

[golden bone]

Given that the link launches JavaScript, yes I do think Selenium is likely needed, unless you can reverse engineer the file request with developer tools and bypass the JavaScript.

The accepted answer here may help: https://stackoverflow.com/questions/12146403/disable-firefox-save-as-dialog-selenium

django rest framework, testing
so I put this before my TestCase class

token = Token.objects.get(user__username='admin')
client = APIClient()
client.credentials(HTTP_AUTHORIZATION='Token ' + token.key)

but when I run tests for some reason i get 401s, while when i do this in terminal with python interpreter i get expected responses (200, 201, etc.). What am I doing wrong?

[undone laurel]

Guys, one very small question

What's the best way to ensure that a dynamic task runs only once in celery beat? I'm passing a date and time to this view from the frontend and assigning everything from the minute to the month to the task, but I can't assign the year so the task will repeat once every year right?

If I just set one_off to True will it run only once?

hello I've never made a website before, but I had this idea:
I want to connect my bluetooth headphones to the pc
I don't have bluetooth on my pc

So:
Let's make a website take takes in all of the sound on my pc
Send it to my phone
And my phone sends it my bluthooth headphones

How do I even begin to make this?

heyo does someone know how to correctly set a firefox profile in python selenium webDriver ?

# create ff profile
profile = FirefoxProfile()
#profile.set_preference('browser.download.folderList', 2)
profile.set_preference("browser.download.dir", targetDir)
profile.set_preference("browser.download.manager.showWhenStarting", False)
profile.set_preference("browser.helperApps.neverAsk.saveToDisk", "application/xls;text/csv")
profile.update_preferences()

options = Options()
#options.headless = True
options.profile = profile


driver = webdriver.Firefox(options=options)

i tried the following however got a DeprecationWarning: firefox_profile has been deprecated, please use an Options object profile = FirefoxProfile()

https://www.selenium.dev/documentation/webdriver/capabilities/firefox/

then tried the suggestions in the docu, also didn't work unfortunately 😕

[lethal junco]

please help, I'm having this error when running the Dockerfile

I want to run it via localhost using manage.py

[visual cedar]

Should I use different endpoint URLs for GET and PUT? For example if I want an endpoint to list all of some model X, but I also want someone to be able to pass in an id that represents a model's ID in a database, and the backend would set some flag, lets say.. isdisplayed, to False

I don't have anyone to really ask for what would constitute best practices so I thought I'd ask the hivemind

My initial instinct is that I should probably use two completely different URLs, for example

GET users
PUT users/hide (and I can pass in id: 1 or something and handle that)

But there's probably a non-zero chance that best practices suggest that GET users and PUT users is better?

[native tide]

<button type="button" class="aAr9nYtPsG7P2LRzciXc">Follow</button>

how do i find this elemant with selenium as there is no id or name

ping me when reply

[visual cedar]

thank you. I will try and follow this. I'm worried that I may want to use PUT users/{id} for more than just setting a flag, but then I recall that PUT allows any attribute to be updated huh

So I am responsible for handling what's allowed in the PUT and whatnot then I suppose

Whoa, that's the first time I heard of this. Thank you

[golden bone]

I think it's telling you setup.py doesn't exist in the working directory. If it does, maybe an issue of file permissions?

[golden bone]

Look into xpaths. You can approach it various ways but //button will get you any buttons in general and then you can use the class and/or text to specify

[native tide]

would it be //button[@class='aAr9nYtPsG7P2LRzciXc']?

[golden bone]

That's one way that should work, yes

If there is more than one button with that class you can either get the first one, or get them all

Or specify based on a parent tag

[native tide]

how can i do this?

[lethal junco]

it's in the root directory, maybe on my configuration? here is the configuration of scripts/ci-runner.Dockerfile:

should I add something on that configuration?

[unborn lion]

Is it possible for python to find out what website is open on your pc?

[inland oak]

everything is possible, but it would PITA (Pain In The Ass) level of task.
Because you are wishing for action that is often performed by virsuses and other mailware

[unborn lion]

oh

but do you know how to do it?

[inland oak]

among ways that aren't PITA

you can track your own web site that is opened

by making some JavaScript hooks

Also as not PITA would be to have it in Chrome Extension functionality, it should be having access to this data with right permissions

[unborn lion]

ohk

[near ravine]

@inland oak isnt it easier to just see which tabs are open

and then if lets say instagram.com is open it will basically play a sound

[wet sparrow]

I was learning about flask API

in my main directory, why did this pop up

Is it safe to delete
.vs and database.db
This is all that I've imported

[mental summit]

You probably shouldn’t delete database.db. That’s the file that acts as the database.

[near ravine]

how to block all websites except 2 in python?

[inner bramble]

you're gonna have to explain a little more in context

[near ravine]

basically im making a program to help me focus

currently i have made it so that if i open some games it airhorns and sends a notification

but.. i also wanna do the same to all websites except for google drive and gmail

it is ok if whenever i open a website other than that, it gets detected then my program acts on it

[inner bramble]

From what I understand, you want your Python program to detect what website you're on and act on it in the background?

[inland oak]

the task can be fulfilled in the nice way only in Javascript

while it is still possible in python, it is by magnitude harder

[near ravine]

ok

[near ravine]

bingo

[near ravine]

how can i do that?

[inland oak]

https://developer.chrome.com/docs/extensions/mv3/getstarted/
Get started with manifest 3 chrome extensions

write in its settings to access the necessary Chrome API that allows to check current urls
https://developer.chrome.com/docs/extensions/reference/

one of next permissions should be containing the access to urls

"permissions": [
    "webRequest",
    "tabs",
    "http://*/",
    "https://*/"
  ],

then do you deed with the acquired data

[near ravine]

ok

[near ravine]

where do i write the settings of the extensions

im not sure i get you

do you have sample code or something?

[inland oak]

https://developer.chrome.com/docs/extensions/mv3/getstarted/ read get started tutorials

or find examples of the code in google

[near ravine]

ok...........

[inland oak]

although official docs are better

[near ravine]

but why do i need to make an extension tho

[inland oak]

because extension has access to browser currently opened urls

extension is in browser application, it has access to do the job you wish

[near ravine]

ok.........

[near ravine]

@inland oak update

i made the extension

[near ravine]

now i gave the chrome api access to check tabs n stuff

now how can i integrate that with python?

@inland oak

[inland oak]

Sorry, can't resist writing meme as a joke-answer

[inland oak]

Chrome extension is just another frontend application, treat it like that, (like already rendered web page)

if you wish its integration with backend python application...

request in it endpoints of your python backend application

that accepts and outputs data in JSON data

So... like, write in JavaScript, request to query your python backend, https://yourpython.com/allowed_urls_to_visit
and get answer like
[
"blabla",
"blabla2": { "tratatata": 123 }
]

to acquire list of allowed-white listed urls or any other data

in similar requests you can input data to python

[near ravine]

as far as I know, Ruby on Rails and Django are more or less the same thing

Django could be more popular/easier to find work with in his region

Popularity wise ruby and rails are declining a bit right now. So you could switch to python for a better ecosystem maybe.

Hello, is it possible to provide auth from another framework and authorize it on Django? I know there is OAuth, but I mean can I do the authentication on another framework like express, laravel, etc... and the tokens get authorized by Django.

[inland oak]

yes

JWT tokens as a choice should work fine

procedure

1. Client AUTHed in your another framework, your framework has SECRET_KEY_1 and sent a sticky cookie with JWT stuff to identify user
2. Your user goes to Django Framework, with same SECRET_KEY_1, you validate sticky JWT token, success

[rotund perch]

it need some configurations on settings.py on the default authentication or similar right?

[hybrid iris]

How do I fix??

[thin marten]

https://iq-inc.com/importerror-attempted-relative-import/
this has 2 solutions, the first is quick and dirty and i dont suggest following, the second solution is much better and involves essentially creating another folder to put the different views, auth, signup, etc in

[hybrid iris]

I have an init

@thin marten

I still need help i TRIED.

[thin marten]

leave init where it is and and add a new folder titled "pages" or something then put auth, models and views in it. youll have to restructure some imports in the code for the new locations but from there you should be able to from pages.models import User

it wont be with these names specifically but the file structure should look like this inside the "website" folder

[hybrid iris]

They are in a folder.

[thin marten]

send a picture of the file structure

[thin marten]

hold on

[thin marten]

foo = "flask web app" in your structure

you may want to rename the folder from views since it will likely cause namespace conflicts (in the example i put)

[thin marten]

i dont know what else to try from here. if your following the video i think you are id double check the file structure and make sure its the same as his and other than that im not sure. sorry

[twilit needle]

Lol jwts are bad😁😂🤔

You should just use simple random tokens for authentication

[inland oak]

woah? They are the best for microsrvices

[twilit needle]

I know this is a hot take

But trust me

https://fly.io/blog/api-tokens-a-tedious-survey/

[inland oak]

I will not 😠
How am I going to verify your random tokens in other microservices
and JWT transmit me additional data with them to tell user rights, i wish to have it

[twilit needle]

I meant using jwts itself as an api token is bad

[inland oak]

sticky cookie

[twilit needle]

??

[inland oak]

once user authes in our auth api
we send in reply Sticky Cookie with flag to forbid javascript access

the cookie is sent automaticlaly back with every request from the user to the same domain

[twilit needle]

Alright, what's in the cookie?

[inland oak]

we just read his side car to the request

[inland oak]

additional payload to every request ;b with expiring feature

capable to carry up to 4k of information

4 kilo bytes

[twilit needle]

I don't understand what you mean tho

How's this related to jwts

🤔🤔

[inland oak]

we send JWTs in Cookies

[twilit needle]

Hmm but why

[inland oak]

we store JWTs in Cookies

[twilit needle]

Is it to be stateless?

[inland oak]

Because it is convinient and better secure! Frontend code has no access to Cookies with javascript forbidden state flag in them

[twilit needle]

Imo statelessness is impossible when you handle authentication

[inland oak]

All auth stuff of backend is obscrured away from frontend 😉

[twilit needle]

No, I meant to ask why send jwts in cookies lol, not why you send sticky cookies

You could send simple random tokens instead

[inland oak]

how do I validate random tokens

and how to i transmit necessary additional info inside of them

that tells me the info of user

how the fuck do I validate it is the same user at all, how do I identify him if he came to me with random token

JWT can tell me exactly which user it is

with adding any additional info about him, email, user id in database or anything i want

[twilit needle]

Store the token in a table??🤔

[inland oak]

WHY!?!?

it is additional request to SQL Database

it is uneffefficient!

and I would need validate every time from database!!!!

[twilit needle]

You will get the current user from the database anyways right? Why not make a join

[inland oak]

JWT token can be validated without database, even in other microservice

JWT token can be used to AUTH ACROSS MULTIPLE MICROSERVICES WITHOUT VERIFICATIONS FROM DATABASE!

no additional requests

we auth once, one request to SQL database at the beginning and that's it

[twilit needle]

Okay, but this involves tradeoffs too

You cannot invalidate tokens at once

You'll need a blacklist

[inland oak]

I can put inside as much invalidating things as I wish

[twilit needle]

Which makes the whole flow stateful

[inland oak]

I can put time expiring into it
I can put into it email and any other user info

anything that I want to invalidate it

time expiring should be enough as it is working across microservices to invalidate them

[twilit needle]

Let's say you have a jwt with an user I'd as payload. It expires in 5mins. When the user is deleted from the database, the jwt has stale payload

[inland oak]

sure, that's a bit of trade off, but usually user requests to delete himself, then I could delete his cookie during the request, or during his next auth operation

or since he was deleted... if he would try to make operation that he is not able to do any longer, he can just encounter 403 forbidden access ;b

the service will work fine

[twilit needle]

This doesn't necessarily need jwts, you could do the same thing without the tradeoffs mentioned above using hmacs

It's in the article I linked above

[twilit needle]

Same principle applies

alright though, this was a fun debate/ discussion lol

[serene prawn]

Tbh they're still vulnerable 🤔 during an xss attack attacker still can send requests to the service and browser would attack cookies to them.
I'd say it's the same level of security as storing jwt in memory and adding a random string in a cookie and it's has in jwt

In both cases attacker could use jwt in client's behalf but it can't be stolen or can't be used outside of user's browser

[wild iron]

in django while registering a new user how do i check if that username/email is already registered or not

[serene prawn]

User.objects.filter(Q(username="Username") | Q(email="YourEmail))
or you could do separate queries for username and email too

[wild iron]

ahh lemme try

[serene prawn]

This query would select all users who's username or email matches

essentially where username = 'Username' or email = 'YourEmail'

this views.py and register.html

[serene prawn]

I don't need the form 🙂

[wild iron]

lol i will just delete it, coz its taking too much space

[serene prawn]

You could just do

if User.objects.filter(username=username)):
    messages.warning(request, "Username already exists.")
    return redirect("/register")

instead of User.objects.filter(Q(username="username"))

[wild iron]

lemme try that out real quick

[wild iron]

this worked

thankss a lot mate

[barren lava]

I am looking for Python Website and application Jobs with Django, Flask, Fast API.

What's the difference between % and %- in Jinja?

[inland oak]

% is the default one for programming actions

%- does same actions, but removes spaces at the left, -% does the same but removing spaces at the right

[serene prawn]

@inland oak You store both access and refresh tokens in cookies?

[inland oak]

Let's assume yes.
(Truthfully so far my access and refresh token were the one token)

[serene prawn]

They're still vulnerable to XSS attack (it's not like you could really do something about it) 🙂
I guess all you can do is minimize the probability of xss

Mainly cleaning everything you're displaying on your page, frameworks usually do that for you

Essentially storing it in cookie prevents attacker from stealing it but it still can be used in client's browser as i mentioned

[inland oak]

my web site is not having user written content, so xss risk is highly minimized I think

it could happen only if user has something like usafe plugins installed

[serene prawn]

Yep

[winter hearth]

Ah okay, makes sense.

[covert trench]

I have one view (ModelViewSet) which is for shop owner and for normal user of shop who wants buy smth. Shop owner has access to all methods, he gets full data about shop on GET request. Normal user has access only to read and he can get only selected data, not all data about shop. What is better solution?

1. One view, 2 serializer for this view (get_serializer_class) + override get_queryset and get_object methods where I will filter it (because when owner of shop want to get all data about shop I filtering it owner=user and when normal user wants some data about shop using same view I don't want to filter it)
2. Two other views with 2 other serializers - one for shop owner and one for normal user
   I have many views with situation like this, so using first idea I would have much code duplicate (bcs of overriding getqueryset i getobject)

[random sand]

django

help needed

cant figure out the problem

[covert trench]

What is your error?

[native tide]

yo guys, can i have some help whit javascript?

why this don't work? js for (key of setup_methods) { var e = document.createElement("button"); div_input.append(e); e.onclick = key["method"]; e.innerHTML = key["nome"]; }this code should add some buttons on a div but nothing happen and i get no errors in the console.

[tropic blaze]

Hey guys I am new django and wanted to ask is it compulsory to have a static folder in your django project?

[frank shoal]

for (const key of setup_methods) {

[frank shoal]

if you have static files, yes

[tropic blaze]

I want to build a simple web page where we can upload any particular Image.

[tropic blaze]

Okay

[stark tartan]

You can use fask or django

[stark tartan]

Come on VC

[stark tartan]

No you need to have media folder

[tropic blaze]

I am using Django

[tropic blaze]

what's a media folder😅

[mental summit]

It holds image uploads

[tropic blaze]

Okay now I get it

[wheat verge]

so i was watching a tutorial and made a project that was there in the tutorial and after hosting i saw this when i was sharing the link to one of my friends how is this possible that dennis ivy (the youtuber btw) name is shown here?

[wheat verge]

what code?

[inland oak]

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

[wheat verge]

copied a code from a youtuber to study and learn deployed it in heroku and its showing this....text ...the name of the youtuber is Denis Ivy

its a django project so i dont know what code do you want

[dense slate]

The page that the link goes to has meta information like author, link, etc. and it is pulled from there when the link is shared.

Look at open graph to setup your page to have meta information like this. It has to do with SEO if that helps.

[wheat verge]

thank you

[flat frigate]

guys my page keep reloading while i am streaming by openCV anyone know any solution to stop this reload?

[buoyant cypress]

Hello, i'm doing an app with django backend and nextjs fronetend, i was able to finish my authentication system using jwt http only cookies. Now my question is, what would be the right approach to obtain and update the user information?
i have a refresh and access token on the browser plus an endpoint /verify in my database to check the token

[dense slate]

What do you mean by update user information?

[buoyant cypress]

I mean that, in addition, they have objects (if it were an application like instagram they would have posts, and comments, etc) and they must be able to upload and update this information

would be information linked to the user

[dense slate]

I mean you just update the info like you normally would, sending a mutation/call to the API to update the user information with whatever data you send, but you use the cookie to authenticate whatever you need to in order to allow for it.

Using django-jwt?

and REST or graphql?

[buoyant cypress]

i'm using rest_framework

with simple_jwt

[dense slate]

So when you signup, you send a request to the api with the information.

[buoyant cypress]

yes

[dense slate]

Same thing when you update information.

Just send the data from the form to your API.

Does that answer your question? I'm not sure if that's what you were asking.

[buoyant cypress]

the thing is that when i send the data

how i know which user update

[dense slate]

I assume the cookie has user data in it.

I use django-jwt and it sort of handles all of that.

[buoyant cypress]

ok thanksss

[quick isle]

hi guys, i have a problem with running multiple django website with apache. first one work fine but second i get wsgi error Timeout when reading response headers from daemon process

[dense slate]

I bet simple-jwt has a function to handle it for you.

In django-jwt/grapehene, I just have the login_required decorator that calls the function to validate the cookie.

And if it's valid, then it uses info.context.user or something to grab the data.

I don't know exactly where it holds that.

[buoyant cypress]

thanks, i will read the documentation to to look for some functions or clarify my doubts

[rare lagoon]

Can you use bootstrap with flask?

[quick isle]

does anyone can help me with apache2?

[dull isle]

hey guys so i have a discord bot and i wanted to make a website that i could tweak different settings for the bot from. I have used flask a bit in the past and i wanted to know if there was a way to asynchronously start the discord bot and the flask app main threads so that they could communicate with each other

i've had some trouble with doing that, so can someone point me in the right direction or tell me if i'm even going about it the right way?

[unique shore]

Like a bot dashboard?

Check out

!pypi quart

[lavish prism]

quart v0.16.2

A Python ASGI web microframework with the same API as Flask

[unique shore]

!pypi quart-discord

[lavish prism]

Quart-Discord v2.1.4

Discord OAuth2 extension for Quart.

[serene prawn]

start the discord bot and the flask app main threads
There's a thing: You don't
Depending on what settings you want to tweak they could just use the same database

[unique shore]

I mean they should use the same database

[dull isle]

okay, that makes sense, can you point me to an article or video?

[unique shore]

Look at the py pi’s

!pypi quart

[lavish prism]

quart v0.16.2

A Python ASGI web microframework with the same API as Flask

[unique shore]

!pypi quart-discord

[lavish prism]

Quart-Discord v2.1.4

Discord OAuth2 extension for Quart.

[serene prawn]

You don't need quart for that 🤨

[unique shore]

yea ik

[serene prawn]

discord.py would work

[dull isle]

yes, im to do that exactly

[unique shore]

discord py doesn’t make websites

[dull isle]

yeah, but how do i make it send data to the backend client?

[serene prawn]

They should be separate applications

[unique shore]

mhmm

[serene prawn]

@dull isle You can connect flask app and discord bot to the same database

[dull isle]

okay, do you have a database reccomendation?

[serene prawn]

Postgres is good

[unique shore]

Postgres

[dull isle]

alright cool!

[serene prawn]

Personally postgres + sqlalchemy as an orm

[dull isle]

ill look into that, thanks, y'all

i dont know enough about backend to understand what you mean 😅

[serene prawn]

It's a popular python orm, you'd probably use it with flask

[dull isle]

okay, cool, ill look that up too

[unique shore]

unrelated question but do you would prisma is better than sql alchemy or could provide better functionality. I think there is a Python version for it

[serene prawn]

They're different things

[unique shore]

mhmm

[serene prawn]

prisma itself is not a relational database

[unique shore]

ik

[serene prawn]

sqlalchemy is working with sql databases (sqlite, postgres, mysql, etc)

[unique shore]

It’s an ORM

ahh so prisma isn’t just for only sql databases basically

[serene prawn]

Yep

[unique shore]

ok

it could still work though in some sense right?

as an orm

[serene prawn]

It won't work with sql databases 😅

it would work with prisma db

[unique shore]

ok

thanks for the info

[serene prawn]

Oh, actually, wait 🤔

[unique shore]

?

[serene prawn]

I actually meant cassandra 😅 It's a db that discord uses

Prisma should support sql databases

[unique shore]

ok

all good

[unique shore]

yeah I was confused because I was watching a video. It said it works with sql databases

[serene prawn]

From the first glance - i don't really like prisma:

posts = await client.post.find_many(
    where={
        'OR': [
            {'title': {'contains': 'prisma'}},
            {'content': {'contains': 'prisma'}},
        ]
    }
)
# vs
select(Post).filter(or_(Post.title.contains("prisma"), Post.content.contains("prisma")))

Just a personal thing i guess

[unique shore]

Understandable

[serene prawn]

sqlalchemy supports a lot of weird cases, you could configure a lot of things

Anyone here experienced with flask? My current file structure is something like this:

app/
 - templates/
   - test.html
 - views/
   - main_view.py
 - __init__.py
main.py```
However when i try to load a template `test.html` from main_view.py it returns a TemplateNotFoundException

[frigid sigil]

I would really appreciate if someone could help me on this, been stuck for a bit haha

[serene prawn]

By convention templates are located directly in templates dir, yours is app/templates, you could pass a template_folder parameter into Flask

e.g. Flask(template_folder="app/templates")

[tawdry chasm]

it dosent load the image in else. Any help?

it dosent load

the image exists tho. U can copy and paste it in ur browser

[dusk portal]

use .url instead of _url dude

It's always use of . When we fetch remember that

N it will work

[snow edge]

that one works fine. the problem is in line 4

[dusk portal]

Kinda impossible dude

See ur if statement

change it to
guild.icon.url

Not guild.icone_url

[snow edge]

icon.url wont work dude

[dusk portal]

Just try

As I said

[snow edge]

i just did

[dusk portal]

It's saying

U don't have any object named icon on the db (or this particular post)

[snow edge]

no

it is saying guild object has no attribute icon

the syntax is icon_url

[dusk portal]

Show me ur models

[snow edge]

I'm using a module called quart_discord

[dusk portal]

Ohh

But it isn't also loading ur if statement

[snow edge]

OH yeah z🤦‍♀️

but no

[dusk portal]

Wait lol

I'm sorry

@snow edge

[snow edge]

yeah

[dusk portal]

Ik solution of this

            {% endif %}

dosent throw error

but it is still the same

[snow edge]

this

[twilit needle]

I dont use jinja2 that much, the last time I did was to do server side template rendering

[snow edge]

i just started learning

[twilit needle]

Alright, so lemme help you here

What's the error you are facing

[snow edge]

not any error but the else statement in my code dosen't work

[twilit needle]

Could you do a quick test

[snow edge]

it dosent load the img

[twilit needle]

print(guild.icon_url)

[snow edge]

sure

[snow edge]

ok just a sec

[twilit needle]

Before you render the template

[snow edge]

@app.route("/dashboard")
async def dashboard():
    if not await discord.authorized:
        return redirect(url_for("login"))

    guild_count = await ipc_client.request("get_guild_count")
    guild_ids = await ipc_client.request("get_guild_ids")

    user_guilds = await discord.fetch_guilds()

    guilds = []

i dont have guild obj in the py file

[twilit needle]

Show me the full route, please

So that I know what variables you pass in

[snow edge]

@app.route("/dashboard")
async def dashboard():
    if not await discord.authorized:
        return redirect(url_for("login"))

    guild_count = await ipc_client.request("get_guild_count")
    guild_ids = await ipc_client.request("get_guild_ids")

    user_guilds = await discord.fetch_guilds()

    guilds = []

    for guild in user_guilds:
        if guild.permissions.administrator:
            guild.class_color = "green-border" if guild.id in guild_ids else "red-border"
            guilds.append(guild)

    guilds.sort(key = lambda x: x.class_color == "red-border")
    name = (await discord.fetch_user()).name
    return await render_template("dashboard.html", guild_count = guild_count, guilds = guilds, username=name)

here it is

i use ipc to connect

with my bot

[twilit needle]

Could you please explain further?

If your else block is not rendering it means that every guild has its icon url

Every discord guild has one, even if you dont set one, discord creates a default icon everytime, if I'm not wrong

[snow edge]

when tehe guild has noicon, it is defaulted to "none"

[snow edge]

if no custom icon is setup, it sets the icon url to none. If it is accessed by api, it is none

but u can see the icon in ur client

[twilit needle]

Could you print the guilds you have to the console and check the icon URLs for each?

[snow edge]

okay just a sec

[twilit needle]

Just do

for guild in user_guilds:
    print(guild.icon_url)

[snow edge]

yeah it prints

[twilit needle]

So every guild has its icon url set

[snow edge]

but dosent count guilds with no icon_url

[twilit needle]

??? What do you mean

[snow edge]

these guilds dont get counted

with default icon_url

[twilit needle]

Well no, they are icons too, right?

[snow edge]

api ignores them

they are none

[twilit needle]

But I dont see any None in the terminal

[snow edge]

it dosent print none idk why

but it dosent count them too

[twilit needle]

How are you sure

[snow edge]

i clicked on each of the icons

to check

none of them are default icon url

i even counted

only them dont get counted

[twilit needle]

Well, maybe in those guilds you dont have administrator permissions

So you dont collect them

[snow edge]

i'm owner in them

[twilit needle]

Hmm, what is rendered in the browser?

[snow edge]

once with default icon r not rendered

[snow edge]

here is the code

[twilit needle]

Could you open devtools

And tell me the icon url for those servers

[snow edge]

ok

https://discordapp.com/assets/322c936a8c8be1b803cd94861bdfa868.png

icon of the guild with no icon_url

but it dosent render

meaning it gets added but not rendered

html problem then ig

[twilit needle]

So.. the else block executes properly?

[snow edge]

yes

[twilit needle]

This might be a css problem too

Your red-border class maybe hiding it

[snow edge]

i tried to remove guild.class_color

it still dosent work

<img src="https://discordapp.com/assets/322c936a8c8be1b803cd94861bdfa868.png"/>

[twilit needle]

<img src="https://discordapp.com/assets/322c936a8c8be1b803cd94861bdfa868.png" />

Try this?

[snow edge]

ok

nope

[twilit needle]

Try pasting in some other url

[snow edge]

ok

i tried adding another img. Dosent wok as well

[twilit needle]

Then it might be an issue with your markup

But as I said I haven't used jinja a lot

So I cannot help you further, maybe someone else will!

[snow edge]

ok thanks for your time :)

[gentle ingot]

So this works when im using python terminal but it wont actaully show the country when i try to put it in my flask_app.py

SyntaxError: invalid syntax

[stark tartan]

What is that

[inland oak]

a joke to your msg with . that you deleted

or I am just too nervous due to my product coming to production launch. That could be too.

[stark tartan]

Why are you nervous

[inland oak]

I am not sure if I anticipated everything. Well, everything is impossible to anticipate.

the product is made out of microservice architecture, in kubernetes cluster, with at least 4 different applications, backend / frontend and e.t.c.
everything is covered with unit and integration testing, everything is automated with gitlab CI pipeline, I made in 5 layers coverage of infrastructure with monitoring / logging systems

But did I consider everything? Is it ready to have reliability 99%+ up time?

will I be able to react in time to scale the infrastructure?

Oh! I remembered. I need to setup auto alerts!!!!!!

[stark tartan]

Ohh my god 🙏

I just learn docker 😅

[inland oak]

I was just responsible for every part of the product alone. And I am a bit nervous if I was able to anticipate everything

[stark tartan]

Is this the company project

[inland oak]

yeah

the thing is. microcompany / startup

So I am reponsible for everything of the tech nature

I have no one to blame except me for any software related fuck ups 😉

[inland oak]

I guess reading SRE book is kind of like reading a book of all possible illnesses by the doctor

I start to see posibility where the service could have complete breakdown in different scenarios

or I just should go to drink beer 🍺 to calm down

surprisingly it is very hard to make sure that web service has 99%+ uptime/reliability

so many things can go wrong

and would you be able to notice them, or it would go wrong and you did not even notice? That's the problem

highly efficient monitoring / logging is required just to see it, the question raises though, will it be enough

[mint folio]

@inland oak Don’t think you should really worry or get too stressed over this. Bugs, issues or unnoticed problems will always be there. In my case every project we take we have dozens of devs, UX, QA testers and still there are bugs. Sure you can do things to avoid issues like this, but it doesn’t matter if your a lone wolf or working in a large team. The system will never be perfect, for everyone.

[inland oak]

Yes, I know that.
But still.... I question myself I did not miss some highly important best practice / possible moment that I should have done?
I guess I am just mentally checking every part of the product if I did not forget something INCREDIBLY simple and stupid

Something like... a hole in security that can be easily exploited 😉

Or if I made sure to enable prod level scaling of the every part of application in every part of the product to handle real workflow

[mint folio]

Seems you are thinking a lot into the future.

[inland oak]

Anyway, the list in the mind I think is fully checked.
The only possible issues I find... I did not setup auto alerts yet, and I did not install higher storage for logging database.
Besides that the only thing is left to choose the server resources to run the production, having it approved and to make performance testing that it works well

and I should be ready to go

[mint folio]

You generally don’t worry about scaling or performance until it becomes an issue. Optimising for what might be needed in the future now is always a bad idea.

[inland oak]

oh believe me, it should be at least dumb checked in the beginning.

Gunicorn by default is locked to run in just one CPU, regardless of available CPUs at server

if something like that would have been missed, it would be disaster 😉

[serene prawn]

Depends on the amount of workers

[inland oak]

yeah, and default is one worker

[serene prawn]

Workers also can handle multiple requests if you use something like gevent worker class

[mint folio]

Like I said worry about performance when it matters. If it’s that critical or important before your app even hits production, then tell your company you need additional resources in order to achieve what you are trying to do. And that would mean consulting or hiring those who know about this.

[inland oak]

I think application should be async in order for that to work one

[serene prawn]

🤔 Not really

[inland oak]

really?

[serene prawn]

Your app should be to handle simultaneous connections despite being sync

[inland oak]

well, if there are at least several gunicorn workers, it would handle

I made sure to have a test with quering endpoint multiple times

including quering some simple endpoint with sleep(1)

[serene prawn]

My app was able to handle simultaneous requests using single gevent worker 🤔

I was sending a request to an api and receiving a callback at the same time

Default worker just fails to handle second request as expected

[inland oak]

I mean... yes gunicorn worker handles multiple requests even if he is one

but if request contains time sleep(1)

it will wait 1 second before going to finish next request

[serene prawn]

sleep is not cpu bound though 🤔

Are you implying that gevent would just put requests into a queue?

[inland oak]

if it is using sync function like time.sleep, highly likely yes

if uses async sleep, then perhaps not

[serene prawn]

It should handle them concurrently though, let me check 😅

[inland oak]

time.sleep is sync, it should prevent concurrency

[serene prawn]

Again, how was i able to receive a callback with gevent then? 🙂

First request won't finish until callback is done

[inland oak]

well, I can't see you code to know what sync stuff you have
regardless if you have it or not, the first request would finish in time, because... the worker would be just locked to process it in sync way for you

the trouble would be for second-third and e.t.c. request made in parallel

[serene prawn]

Not a lot of sync stuff, mainly database and http calls 😉

I mean, i essentially have two requests running at the same time:
User makes call to Django, it makes call to an API
API to process this requests sends a callback to Django, we have 2 simultaneous requests

[inland oak]

import asyncio
import aiohttp  # pip install aiohttp aiodns
import pytest
import time
pytestmark = pytest.mark.asyncio
async def test_django_with_sleeping():

    async def pinging(
        number: int
    ) -> dict:
        start = time.time()
        url = f"https://my_url.com/worker/ping_with_sleeping?format=json"
        print(f"func=install, type=started, number={number}, time={start}, url={url}")
        async with aiohttp.ClientSession() as session:
            resp = await session.post(url=url, data={"password": "password_for_test"})
        data = await resp.json()
        end = time.time()
        print(f"func=install, type=finished, number={number}, time={end}, delta={end - start}, data={data}")
        return data

    results = await asyncio.gather(*[pinging(number=number) for number in range(80)], return_exceptions=True)
    print(f"finished, results={results}")

i like async because it allows me to query same resource in hundred amount of times while using just one CPU

quite efficient to test application 😉

[serene prawn]

Users request can't be done until django is done processing second request(callback)

[serene prawn]

Try locust

[inland oak]

xD, too much for me at the moment

[serene prawn]

from locust import HttpUser, task

class HelloWorldUser(HttpUser):
    @task
    def hello_world(self):
        self.client.get("/hello")
        self.client.get("/world")

I am having a bottleneck in the main... part, which is resolved through Celery to distribute the workload across multiple servers

I tested and knowing for sure the limits of the bottleneck

[serene prawn]

What kind of workload?

what's the difference between flask-login, flask-admin, and flask-security?

[crude badge]

Are any of you folks using remote development? What does your setup look like?

[inland oak]

rarely. vscode has remote ssh plugin

but using it usually a really bad practice for me

[crude badge]

Why?

[inland oak]

so i don't do it

[inland oak]

because code is supposed to be developed locally in my environemnt, submitted to git cloud repository
and with CI/CD pipeline automatically deployed to server

coding in remote environment is bad as bad it is to code in production/staging directly

it means I did not do proper job to setup development environment and development pipeline

[crude badge]

I hear that.
But there are some benefits such as taking advantage of “unlimited” storage and better GPU cards etc

[inland oak]

I mean... I am having dev PC as Linux, it is not different in capabilities to servers in my case

[clear nymph]

Hello when i upload files from form with

fs = FileSystemStorage(location="/media")
fs.save("filename", request.FILES["file"])

It gives Errno 13 Permission denied

i have
MEDIA_URL = os.path.join(BASE_DIR, "media")
MEDIA_ROOT = os.path.join(BASE_DIR, "media")

in settings.py

i wrote

Alias /media /var/www/TheMPDB/media
<Directory /var/www/TheMPDB/media>
Require all granted
</Directory>

to my apache config

[inland oak]

perhaps you have chmod permissions broken

try chmod 777 -r /path/to/linux/folder/with/media/static/files

it permits everything 😉

[clear nymph]

thanks i fixed

[frank shoal]

It's really chown www -r /path/to/static

[autumn veldt]

someone know how can i see if page is doing playing sound in selenium?

[golden bone]

I've never done it and it doesn't look simple, but multiple StackExchange answers come up if you search

[inland oak]

It will not fix all types of related problems to it.

For example your regular user, root or regularuser. After chowing, and launching default nginx, u will still face the related to it errors, because it launches as nginx user by default

[rare lagoon]

Whats the difference between a web framework and a web server?

[golden bone]

A web server is an application that provides the web pages to clients. When you put a URL in a browser, you're pointing your browser to a specific web server. Nginx and Apache are web servers

A web framework is a library that helps developers build web pages. Django and Flask are web frameworks

All web pages run through web servers but not all are built with web frameworks. A web framework needs to run on a webserver to be accessible

[rare lagoon]

So I can run a web framework with a web server if my app needs to?

[golden bone]

Yes, if you have an app with a web framework you must have some form of web server to run it, even if it's just a built in development server like Flask has

[rare lagoon]

Got it, thank you

does someone here got an idea regarding flask restful api with swagger 3.0? im currently encounter an error with null value

how can i replace �� or unicode characters on some websites? or i can copy the text from them but can i put them somewhere and have it replaced?

[hollow ocean]

You're working on a web application for automating ads on Facebook and Instagram. The manager has informed you that following user feedback, you need to add a new section to the app to view your weekly campaign performance. The section should allow a user to select a time period, a campaign, and display metrics for that campaign.

Metrics are: impressions, coverage, clicks, cost-per-click, clickthrough rate.

The user must also download this information as a CSV.

Propose an implementation plan for this new section.

In your reply, mention the following:

• How many new pages would you make for this section?
• What existing pages would you modify (if necessary)?
• How many new endpoints would you implement in BE for this section? What would be the functionality of each proposed endpoint?
• What database would you use (relational vs. others)?
• Other details that you consider relevant

Is anyone able to help me with this?

thanks mate

[tropic blaze]

Can anyone guide me I just want to create a webpage like this with Django -

[unique shore]

That there is just html and css

you can use Django and it’s Jinja template engine, then serve the template to an endpoint

or url

[tropic blaze]

I basically want to take an Image upload save it in a folder and do some stuff with that image. Completely new to Django so I thought I should give it a try using Django

[unique shore]

as I said, what you want to do is just html and css, you don’t need Django

But if you want to add a backend you would use Django

[tropic blaze]

Okay so Django would not be good for this task?

[unique shore]

If you are just wanting to style, no, but if you want to implement a backend and things like that then use Django

Before worrying about Django, I would first learn html and css as you will need it to make a webpage

[tropic blaze]

What do you mean by implementing backend 😅

[unique shore]

Backend is the logic of the application and how it works behind the scene

[lapis basin]

Front end is what the user can see

[unique shore]

You are wanting to do the frontend, or create and style the webpage like you see it in that image

[lapis basin]

The UI

[tropic blaze]

Ohh yes now I got it

[unique shore]

So before doing Django or any major web development, learn HTML, CSS and JavaScript

Html and css are relatively easy (css does get wacky though)

[tropic blaze]

Okay understood

[unique shore]

Django is a framework for making the backend and API’s

but it does have the ability to render html templates and static files as I said

You can use frontend JS frameworks along with it though

[tropic blaze]

Yeah But Js would be overwhelming for me as I haven't done Html Css. I will go with what you suggested in the first place

Shit man now my project will get delayed

[unique shore]

You have to learn before doing projects man

don’t worry about it, I’m sure you will produce a great project when the time comes

What do even want to make?

you*

[tropic blaze]

Actually in my project there's a really small part of creating a web page

[tropic blaze]

Basically my project is if someone uploads a scanned image of ingrediant list of certain product, I will extract words from it and then display some info about all the ingrediants

This way one can know what they are consuming

[unique shore]

ahh ok

Gl with that

[native tide]

is there a way

to add params to url for

in flask

i tried redirect(url_for(f'index?msg={msg}')) but that didn't work

[proven rock]

Hello everyone

I am trying to roll out a small test app to Heroku that includes a front end client (an Angular app) and an API server (written in .Net Core). I am using Docker images to do this. According to the documentation for containers on Heroku, you are able to push multiple containers to a single Heroku app. I have successfully set it up so the webapp is displayed when you navigate to the URL, but I can't seem to find a way to communicate with the server. Is there a specific URL that links to a specific container? If not, then what kinds of systems can you build with multi-container apps on Heroku?

The documentation does not seem to clarify this. The only answer I could possibly come up with for this is to use one container to receive and answer incoming HTTP requests, while the other containers act as workers for background tasks (although the documentation doesn't seem to detail how the two types of containers would communicate in this case).

Init config

app.config.from_object(Config())

Hi. I'm using flask-sqlacodegen to create the models for an already existing MySQL database that I want to connect to a Flask API I'm developing.

When I check the outfile, I see that one table is created as t_aus_postmeta = db.Table() while the rest of them are created with the class constructor I already know, class DatabaseName(db.Model):

What is the reason for that difference? Will this affect the way in which I interact with the database?

[native tide]

do not worry, javascript is not very had for learn :)
