[uneven plume]

I thought the token would be found in /show_token endpoint

[native tide]

what should i do after htmland css for web development

[junior wraith]

fastapi is working with pydantic very closely, I recommend using it when working with fastapi

[uneven plume]

when I get redirected from callback the token should appear?

[junior wraith]

I changed the value of a token to None

async def show_token(
        request: Request,
        token: str = None
):

just to test the code

change it to the original value - idk what it was

[uneven plume]

oh

it worked!

thx alot 😄 now I can move to next step on my chatapp!

[junior wraith]

cool, have a good one 🙂

[uneven plume]

.bm Nice module to work with fastAPI

[fallow cairn]

In the future, don't do that.

@uneven plume, please enable your DMs to receive the bookmark.

[junior wraith]

yeah, Pydantic is awesome

[uneven plume]

.bm Nice module to work with fastAPI

[serene prawn]

FastAPI uses pydantic internally afaik

[uneven plume]

Interesting, that's good to keep in mind

thx a lot!

[junior wraith]

Oh ya, just wasn't 100% sure

[serene prawn]

Yep, just checked, it requires starlette and pydantic

It uses pydantic for schema generation and data validation

How can I debug mod_wsgi? I think I have it configured correctly, but my Flask app keeps giving 404

The apache error.log file says "file does not exist" for me, and gives /var/www/html/myapp which makes me figure that mod_wsgi isn't mapping the requested URL to my app.

But I can't se anything wrong in my WSGI configuration.

Hi guys, I'm trying to deploy a website using Heroku. Heroku is connected to github and any pushes I make to github will update the website. I am a bit confused how to make my environmental variables private?

These are the variables that I get using os.getenv()

and make private on my own computer

[frank shoal]

don't share your computer and they become private.

Though you shouldn't be using prod instances locally.

[tender moat]

i see but i guess I don't quite understand how the website can use them if I'm not hosting the website on my computer but on the cloud

using heroku

[frank shoal]

you would configure them using the heroku command or via the web interface

[tender moat]

ohhhhh that makes sense

thank you!

[dark night]

Ive noticed the PokeAPI serializes their response to make it easier to read, how can I learn to do that? Is that a result of how they query their database or is it down through your own code?

[frank shoal]

What do you mean by serialize?

pretty printing?

[quick cargo]

generally you dont want to pretty print the responses themselves

most browsers and api clients for testing will pretty print it automatically

[dark night]

I guess so. Ive been trying to find out what it is referred to as and "serialize" was the closest I could find

[quick cargo]

but also the user's responsibility to pretty print if they want.

otherwise you're just gonna be needlessly increasing the response size

[dark night]

I dont think thats what I meant actually. https://pokeapi.co/ In this example, their API returns a lot of data on ditto, but its further grouped by abilities, game indices, held_items, etc

[serene prawn]

You can return related entities if you're talking about that

[bitter spindle]

Have anyone ever tried to access external APIs from django migration file? And did it work as well?

[dark night]

Ill just share a link so I dont flood the chat. https://codeshare.io/LwZM37 currently, the response from the API i'm creating is the top example, but I would like to make it look like the bottom example. How can I learn to do this?

[serene prawn]

Migrations shouldn't depend on an external api, it's pretty bad idea

What if api changes? What if it's unavailable?

Migrations should run and rollback regardless

[bitter spindle]

yes that's right

[simple phoenix]

Serialize means to put in a stream in memory or a file.. the contents of an object or data type.. serialized content tend to be read in sequence from start to end like a file stream

It has a pointer typically to the current node or location in the stream

Nowadays we serialize to JSON too

Much more typical in a Web context although XML, CSV, TSV, Word, Excel i have seen too in prod web code

[simple phoenix]

You can write your own serializer methods or classes to formats if you need to but you need an in depth knowledge of the formats to ensure it works.

Have you set up the domain with your provider?

[mental summit]

I’m pretty sure that you’d need to make #panels a flex container in order to use align-items

[crude stirrup]

Flex container?

Btw I'm kida new to html css

[mental summit]

So like add display: flex;

https://www.w3schools.com/css/css3_flexbox.asp

[crude stirrup]

In #panels or .panel?

Ey it kinda worked

[mental summit]

#panels

[crude stirrup]

But it's kinda weird

I only want 2 boxes in normal view

[mental summit]

Maybe just add margin: auto; to the #panels element and remove the display: flex and align-items: center

[crude stirrup]

welp it came back to the original state

[crude stirrup]

this

[brazen ravine]

is this the right channel to ask about aiohttp? or is there a better one

maybe #async-and-concurrency ? But it's not really a question about async and concurrency, it's about the library itself

[mental summit]

Maybe add display: grid; and align-content: center; to #panels and remove the margin

[mental summit]

Bruh

[crude stirrup]

this kinda works but I want it two by two

css is peyn

[mental summit]

What is #panels parent?

[crude stirrup]

nothing

[mental summit]

So.. the body tag?

[crude stirrup]

https://github.com/m0nk3ybraindead/hata-docs/blob/main/src/static/main.css

basically this

but add the few lines I added above

[mental summit]

Maybe add width: fit-content; and margin: auto; to #panels and remove the existing css declarations there

[crude stirrup]

I have that on plus display: grid; now it's in the center

pog

[mental summit]

Remove the display grid and align-content center

[crude stirrup]

done it's still the same

never mind

but now it's like this

[mental summit]

-_- bruh

Maybe add

display: grid;
grid-template-columns:  auto auto;
align-content: center;

[crude stirrup]

it worked !

but

@mental summit how do I fix that one above

[mental summit]

You’d need to change the size of the content

Wait

was there horizontal scrolling

[crude stirrup]

no?

[mental summit]

What I meant is that did you zoom out and take the screenshot

[crude stirrup]

Nope

[mental summit]

Maybe you need to set the navbar width to 100vw

[crude stirrup]

Navbar?

[mental summit]

Idk it looked like the navbar was smaller

And you said that you didn’t zoom out

Hey guys, can anyone tell me how do I return two variables using HTTPResponse in Django? The below is working:

return HttpResponse("Secret Key: %s" %secret_key)

But, this is not working:

return HttpResponse("Secret Key: %s" %secret_key, "ABC: %s" %sc)

[crude stirrup]

@mental summit oh actually

it is

I actually zzoomed

[mental summit]

In that case you’d need to change the size of the content in some way

[dim plume]

Hello

Is there any services where i can host my fastapi server?

[inland oak]

I would recommend https://hetzner.cloud/ , quite nice prices, quality and easy to use for beginners

[dim plume]

Is there any free ones?

[inland oak]

I don't remember there free ones 🤔

if u wish free ones... there are options too

[dim plume]

i need a free one

[inland oak]

Digital Ocean, Vultr, Linode, AWS, Google, Azure
all provide free servers during first try-period time

all for different time limits though

Digital Ocean 100$ for 60 days

Google 300$ for 3 months / + some servers for 6+ months

[dim plume]

won't it require a cc?

[wild cedar]

#help-candy I sent everything there

[inland oak]

yes it will

[inland oak]

it will cost nothing

[dim plume]

i don't have a cc

[inland oak]

some providers accept PayPal

[dim plume]

Anything else except heroku?

[inland oak]

For free and without security check by cc... I don't know.

raise your own server then 😉

as long as u can have public IP from your ISP

[dim plume]

oh

[hazy bone]

I am testing a simple python socket server where i need to pass files content to the client, and the client can request a file by entering it in the url such as : localhost:8080/nicefile.txt and then i would send that file to them so they can view it in the browser. However how can i parse the url (localhost:8080/nicefile.txt) that they entered so i know which file to send?

[quick cargo]

my advise is use a HTTP server and framework like Gunicorn + Flask

doing it with your own raw socket server is a bad idea

[keen nimbus]

umm.....what?

[hazy bone]

id have to use raw socket programming

[hazy bone]

a client can go onto the localhost server and enter a file such a nicefile.txt in the parameters then i would like to know how to retrieve/print the filename they entered

[quick cargo]

you're going to be writing your own HTTP web server

which I dont advise doing

[hazy bone]

its for my own knowledge learning curve...

[quick cargo]

alr, well for starters forget about serving the file

first step is writing the HTTP server itself

[hazy bone]

host = ''
port = 8080
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind((host, port))
sock.listen(5) 


while True:
    csock, caddr = sock.accept()
    print("Connection from: " + str(caddr))
    req = csock.recv(1024) 

    csock.close()

This simple web server, how would i get the incoming data such as the parameters?

[quick cargo]

thats not a simple web server

that is a basic socket,

[hazy bone]

web socket then

[quick cargo]

you'll need to implement the following for it to be a web server and compatible with browsers

• Flow control
• HTTP/1 Spec parsing
• Body streaming and request parsing / feedback

[quick cargo]

websockets are completely different and are even more ontop of the HTTP spec.

https://github.com/python-hyper/h11 is probably your friend for the HTTP parsing

Uvicorn implements -probably the simplest to understand handling of H11 https://github.com/encode/uvicorn/blob/master/uvicorn/protocols/http/h11_impl.py

[hazy bone]

I think ur overcomplicating this

[quick cargo]

you want to serve a file to the browser right?

[hazy bone]

I  must implement a web server that is capable of serving files from a lo- cal folder. This means that you are only required to implement the HTTP GET method, but you may want to implement the HEAD method as well, as it may be useful for testing. The server should be able to run indefinately, by which it is meant that it should not just process a given number of response and then stop.
The server should work as a plain file server and should accept a path to a folder and a port number. The server may also take an address to listen on, but if this is not implemented, the server should listen on all addresses on the port specified. Files and folders in specified path should be served up by the webserver. If a folder on the server is accessed (with a URL ending in a /) then you should serve up the contents of file named index.html, if one exists, or a listing of the files and folders, if index.html does not exist.

[quick cargo]

h11 is your friend

[hazy bone]

i cant use other libraries or external modules but your saying i should look at the code of h11?

[quick cargo]

you could do an incredibly basic / incorrect web server by just hard coding values and making some broad assumptions about the data you're receiving

[hazy bone]

i think thats fine

[quick cargo]

which, yes, is a bit more simple just reading like 1KB and just hoping it contains everything

however if it's gotta to actually be a correct web server then you're looking at a few thousand LOC

[warped aurora]

Is it a problem to have different ajax requests in the same script file?

[inland oak]

The code is code (At least in programming languages with standard logic). Separation to different files is purely for your own code organizations. So answer, no, there should be no problems from that.

[warped aurora]

ok cool. I've got two different ajax calls that should execute on different button clicks but I'm having a problem handling them in flask. Both calls post to the same route and I thought I could handle it by doing this

def process():
    if request.method == 'POST' and request.form['call1']:
        do something

   if request.method == 'POST' and request.form['call2']:
        do something```
But I'm getting a bad key error 'call1' when I click the button that should post call 2

[inland oak]

btw u have wrong indentation

secondly, checking in python key existence by boollean request.form['call1'] should be not correct

[warped aurora]

ah should be something like 'call2' in request.form right?

[inland oak]

def process():
    if request.method == 'POST' and 'call1' in request.form:
        do something

    if request.method == 'POST' and 'call2' in request.form:
        do something

[inland oak]

yes

request.form['call1'] will just raise an KeyError i think, if call1 is not existing

request.form.get("call1") can extract without raising errors (it should return "" if not existing)

request.form.get("call1", Your_default_value) or you can point explicitely what whouls be returned if not found

[warped aurora]

Ok will give that a try

Hey, does someone know a python library for web push notifications? Creating the vapid keys (private & public) & sending the notification to a browser using the keys? Tag me if you know

[frank shoal]

Yes

[royal musk]

okay, I try it

>>> str(Product.objects.get(id=1)) 
'Product object (1)'

I wanted to get this form:

>>> str(Product.objects.get(id=1)) 
<Product: python_keychain>

I l think you should use str in your model

Does anyone know if django's loaddata command wipes the database before loading the fixtures?

Oh sorry

Yeah it works now

django.db.utils.IntegrityError: The row in table 'blog_comment' with primary key '15' has an invalid foreign key: blog_comment.author_id contains a value 'Ayman' that does not have a corresponding value in auth_user.id.

I get this error while I'm trying to migrate

    author = models.ForeignKey(User,on_delete=models.CASCADE)
    content = models.TextField()

[odd belfry]

which column you are altering?

[fathom mist]

the author, it was set to this py author = models.CharField(max_length=32,default='Unknown')

[odd belfry]

you are changing char field to foreign key field, right?

[fathom mist]

yeah

[odd belfry]

there are several ways

before migrate, need to replace author name with author.id with update query

if author_id not found with current author name, then need to set a valid user id (cause your filed is non nullable)

[fathom mist]

But I don't have author name anywhere

so do I just replace author to author.id

[odd belfry]

yes

[fathom mist]

Cannot assign "'Ayman'": "Comment.author" must be a "User" instance.

I'm getting this error now

hi everyone. I tried to build a flask simple website but it gave me a 404 so I tried on another website I created which was working and it gave me a 404 for all of my websites which are working!

please help me

[normal nova]

Share code

[misty bough]

which one?

[normal nova]

Script that is giving 404

[misty bough]

this is a test I did that didn't work also

all of them are not working

anymore

from flask import Flask

app = Flask(__name__)

@app.route('/')
def hello_world():
    return 'Hello, World!'

[normal nova]

from flask import Flask

I was trying to replicate this flask code in fastapi

[normal nova]

The terminal text

[misty bough]

everything is ok there

[normal nova]

You are using pycharm?

[misty bough]

[normal nova]

I think you are not running the script properly.

Ctrl + s to save file

Run the file through terminal

python filename

And make sure url is using '/' route on browser

[misty bough]

didn't work

[normal nova]

Visit that url and share browser screenshot with url.

[normal nova]

Add '/'

In url

[misty bough]

it removes the / when I press enter

[normal nova]

Route is fine. Code is fine.

Where is the debug status?

It prints 404 in terminal?

After visiting browser

[misty bough]

didn't add anything

[granite solar]

You can close and restart the server

[misty bough]

the number of times I did that is infinite

[granite solar]

okok

i have no more solutions:(

[normal nova]

Update flask to the latest version

Which version you are running?

[wild cedar]

Why does it make it so when the window resizes it moves with it but when I scroll down in the page the background stops? And there is a white part there?

Hello

Is it possible to build an array in a for loop and use it in another loop?

Currently it's being duplicated

In PHP I would normally assign it to a key(based on the index) and display that

[normal nova]

Array1 = []
For I in range(0,5):
   Array1.append(I)

For j in Array1:
     Print(j)

Create empty list before for loop and append that list in for loop.

[misty bough]

didn't work

this is so annoying

it worked yesterday

but not anymore

[normal nova]

Did you moved it's directory?

Create a new environment

[misty bough]

it works

I restarted my laptop

now it's working

[cedar imp]

try to change your port

You don't have a Comment with a pk of 4 in your database

It matches the expected URL but the query to fetch the comment is returning nothing

[thin lance]

just put methd

post or get

[fathom mist]

In which model

[thin lance]

i say this to Ophir

[fathom mist]

Oh sorry

[fathom mist]

But It should be a post with pk of 4 and a comment on that post and that comment needs to be updated

Bruh I just realized I'm using post.id instead of comment.id

[indigo kettle]

UpdateView by default looks for the path parameter called pk. Since you are telling it that the model for PostCommentUpdateView is Comment it is looking for a Comment with pk=4

path('post/<int:post_pk>/comment-update/<int:pk>/', PostCommentUpdateView.as_view(), name='post-comment-update'),

class PostCommentUpdateView(LoginRequiredMixin, UserPassesTestMixin, UpdateView):

[mystic cobalt]

I was wondering how I could create a html button that executes a python flask file in my directory, or if that's even possible.

[visual cedar]

I'm looking to switch between databases depending on how I run Django. For example, it's a huge pain to get mssql server up and running for github actions ci/cd, so I want to use sqlite3 for that portion, but I want to stick with mssql server when I run python manage.py runserver. How do I create this split?

[frank shoal]

Using sqlalchemy?

You can conditionally set an environment variable containing a database url

I.e. dialect://user:pass@host:port/db

https://docs.sqlalchemy.org/en/14/core/engines.html

[frank shoal]

!pypi dj-database-url

[lavish prism]

dj-database-url v0.5.0

Use Database URLs in your Django Application.

[frank shoal]

<@&831776746206265384> here too

[visual cedar]

Thank you. this is exactly what I needed!

[visual cedar]

Oh one question though, it looks as though I should be able to specify which database to run? because the way settings.py DATABASES is written

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': 'mydatabase',
    }
}

Can't I just add the ability to set the DB by adding an argument like python manage.py test --use-db default? somehow? this is probably way more complex but might use less dependencies.. or maybe I have no idea what I am saying

[frank shoal]

Don't see why not

[visual cedar]

Ah my question was a little half baked, what I meant to actually ask is

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': 'mydatabase',
    }
    'db2': { ...
    }
}

How would I tell django to seek out db2 when running python manage.py test or manage.py runserver?

The documentation simply says that "its possible to specify more" https://docs.djangoproject.com/en/4.0/ref/settings/

[frank shoal]

Set a value when runserver is used

[visual cedar]

Do you mean like

if sys.argv[1] == 'runserver':
  DATABASES = { 'db2': {...} }

ah I dont think I can do that since it will tell me that default is required or something

[indigo kettle]

doesn't test create an entirely different database to test on?

I'm not sure this is necessary

it is common to use many settings files, one for each environment you might need like settings_local.py, settings_dev.py, settings_prod.py. You can define different DATABASES in each. Maybe that's what you want?

[visual cedar]

so I thought this was the case too, but when I test using sqlite3 it seems okay, but when I test with mssql configured it throws an error saying pk=1 doesnt exist, but that shouldnt be possible if its a new db being created

[indigo kettle]

https://docs.djangoproject.com/en/4.0/topics/testing/overview/#the-test-database

this seems to describe how new databases are created when testing

[visual cedar]

Upon doing a little bit of debugging, print(Snippet.objects.all()) within my test returns a queryset with pks not starting at 1

Thanks I'll give that a read and see if it gives me hints

[indigo kettle]

do you have many tests which set up and create snippets?

you have a set_up method in your test class I believe that gets run once per test

so you could be creating and deleting many snippets

[visual cedar]

I have two tests, and yeah indeed I have a setup that only initializes an object and creates two snippets

but in my first test case I am not creating further snippets, only this:

        snippet1 = Snippet.objects.get(pk=1)
        snippet2 = Snippet.objects.get(pk=2)

[indigo kettle]

it may be illuminating to print something out during your setup

to see if it is running multiple times

[visual cedar]

Good idea, I'll try that

You're a genius, that was the easiest debugging trick ever

I found out that this whole test thing is being called twice, which generates two sets of snippets

[visual cedar]

The problem is this! Well, not a problem, but I didnt realize that the data is not destroyed at the end of each test, so I am making snippet instances per test

[indigo kettle]

yeah, I had a feeling!

[visual cedar]

is the solution to have a init(self): constructor that establishes my objects?

[indigo kettle]

is it important these primary keys be 1 and 2?

it seems weird to test on that

using set_up should be good

[visual cedar]

Not exactly, I'm new to testing though so I have no idea what I'm supposed to test 😉

My first instinct was to test to make sure models actually get made and they can be accessed

Second instinct was to test that saving them to the db is possible at all

[indigo kettle]

It seems like you are trying to test things which django already tests for thoroughly

you need to test the things you have written

not django's code

[visual cedar]

fair enough, I suppose yeah django does check that I wrote my models and serializers correctly

[indigo kettle]

if you had a custom save method which updates a modified_at field or something, you could create a model and check that the modified_at field changes after re-saving

if you really want to check that objects are being saved you can check the Snippet.objects.count() before. Then save x new snippets and check that the new count is x more than it was originally

[visual cedar]

Ah yes that was my intention, but I wrote spaghetti instead

[indigo kettle]

it's hard to know what to do when you're just starting

I still don't know

so

[visual cedar]

but from what you said, I suppose I should just trust that methods do what I expect them to do if I didnt write them

so maybe checking objects being created and saved is redundant

[indigo kettle]

yeah that's a fairly common idea in testing

I would say it is

[visual cedar]

Ok great, thanks a lot. I learned so much just now

[indigo kettle]

🙂

[fathom mist]

how do I make it use the pk of the post and not of the comment in success url

[indigo kettle]

you changed the url like i posted before?

you could just use self.kwargs['post_pk']

[visual cedar]

Another Django question, but when I run python manage.py runserver, I think the code inside of it gets executed twice. Is this normal? For example if I put a print statement print("print statement inside settings.py") in there, I get this in my console

$ python manage.py runserver
print statement inside settings.py
print statement inside settings.py
Watching for file changes with StatReloader
Performing system checks...

System check identified no issues (0 silenced).

Aha, found the solution. For those wondering, Django does indeed read settings.py twice! This is because Django wraps settings.py and does things at a lower level with it, so print statements will appear twice.

It is not a bug though apparently!

More reading revealed to me that

Django uses two process for the reloading feature (ie. restart on code change), if you run ./manage.py runserver --noreload you get only one process.

Sorry for answering my own question. I figure this will help those who try to use search in discord

[fathom mist]

Yeah, but I forgot to do post_pk and just did pk

[fathom mist]

But then I get errors and my urls in my post_detail file are not working

How to serialize a response containing nested list, inner list are list of objects.
something like this, [[obj 1, obj 2, obj 3], [obj 4, obj 5, obj 6]]

I'm able to serialize, [obj 1, obj 2, obj 3] by passing many=True in schema object for the model, but in the previous response the same schema is returning empty responses.

see the logs, it's printing correctly but when returning the list getting empty response in the list

[heavy dagger]

why doesnt this button work?

[tiny snow]

I think it's because the paragraph is not loaded before the script tag, because it's after the script tag

[heavy dagger]

oh so the script should be inside body?

[karmic spoke]

yeah

[heavy dagger]

alright i got it

thanks

[karmic spoke]

or just make a .js file

[tiny snow]

Usually, scripts are put at the end of the body tag

[heavy dagger]

yeah and?

[karmic spoke]

and add the <script tag on the end of body tag

[tiny snow]

But, yeah, a file is good too

[heavy dagger]

script sclrc

src*

okay

[karmic spoke]

with src='yourfile.js'

[tiny snow]

yeah

<script src="yourfile.js"></script>

[heavy dagger]

ayt tysm

Yep. I couldn't see an explicit API section and most companies won't allow scraping by default

[karmic spoke]

Wtf why

It's just bundling info which is available for everyone

[heavy dagger]

even after the script is at the end of body tag, the button continues not to work :(

[karmic spoke]

you have to add the id='demo' to the button

[heavy dagger]

to the button aswell?

change your function name to something else, for example "onClick"

What if you put the script tag between the paragraph element and the button element?

[heavy dagger]

No heres the problem what i found

the script inside onclick should be put in double quotes

like onclick = "script"

and i used java script double quotes aswell

so like if i used single quotes there wouldnt be a problem

Hello folks,
I'm trying to register a blue print in flask that will handle custom exceptions,

when I do app.register_blueprint(config_error_handler_bp), the exceptions isn't caught
why is that ?
but if the blueprint that's raising the exception is the one that's decorated with the error_handler decorator, it does catch it

im making a web application in angular that will need a REST API and websockets (for messages) and authentication, and have trouble deciding my back end framework, it's between flask and django

I've used neither (only spring / spring boot, asp.net / .net), i do have experience in python tho

I've done some research on the frameworks and know that flask is more barebones and django includes a lot more functionality, but I'm not quite sure if django would be overkill for my needs or not

[inland oak]

Django is more product ready solution IMO

there is project to resolve your websockets: Django Channels

there is project to have everything out of the box for REST API: Django Rest Framework

Flask should be having its own analogs though, but I never tried them, just heard about Flask Restful

[serene prawn]

FastAPI could be a better choice than flask

[broken oar]

I was just deciding on learning a back-end framework

[native tide]

why ?

[serene prawn]

It offers the same set of features but is more performant, has built-in DI system and is integrated with pydantic providing data validation and openapi spec

[native tide]

Nice

And what are the options when it comes to deployment ?

[serene prawn]

wdym?

[native tide]

Where can you deploy it ?

[serene prawn]

It's not different from deploying any other python web app

[native tide]

I know, i'm talking about support

because for example

I've just read that pythonanywhere doesn't support asgi

Because I have 2 apps deployed on pythonanywhere

and i thought about switching to FastAPI for better performane

but i think it'll be better to move from pythonanywhere, because it's very limite

d

[serene prawn]

Why not use any vds provider instead?

[native tide]

Idk what that is

[tepid lark]

FastAPI is great... if you're building an API.

[mental summit]

https://fastapi.tiangolo.com/deployment/deta/

[serene prawn]

You mostly see SPA frontends these days

[tepid lark]

I like using SPAs... hate having to build them.

Also, it's easy to package FastAPI in a Docker container with uvicorn and a reverse proxy of your choice.

[serene prawn]

Same applies to any other framework - django or flask as popular examples

It's really more about developer experience

[tepid lark]

Yeah, just run docker on a cheap vps with *docker compose and you're set.

Ooh, DO has a container registry product now.

Anyways, I wanted to brainstorm some architecture.

I have an API backend (Django because we known Django) and SPA frontend. Both the frontend and backend are behind a CloudFront distribution. The backend is ECS and we pass traffic with a certain path back to it. Frontend is served from S3 with CloudFront acting as a CDN.

I'm thinking I could replicate this locally with Nginx as a reverse proxy serving the SPA statically and passing traffic through to the backend container.

[late dock]

cool, thanks :)

[inland oak]

Just using Https will already make stuff encrypted.

Plus u can make VPN tunnels between your servers

[inland oak]

Html form created button to call URL in POST form

Div object can be made looking as custom looking button. Wrapping to a tag will make it calling GET request to specified url

And finally attaching JavaScript event listening to click, can make any object to call any type of request

How to connect celery with flask and Redis as message broker and do machine learning predictions

# flask rest API code for inference

[warped aurora]

ive got a form that looks like that, each row represent a record in the database and I want to submit this through ajax, what would be the best way to pass the data? Should I put each row in it's on form and then try to submit multiple forms at once through ajax? or maybe build a list of some sort and submit the list as a single form?

[rigid laurel]

if you want to do it via AJAX, then there's no trivially easy solution. You'll have to get the values from the form in JS, then send that as a JSON post request to your app, and make any visual updates you want to show to the user in JS

[warped aurora]

It doesn't have to be ajax, but I was more wondering how to handle the individual rows since each row is basically an identical form

I need to create the following flow in django ,. how is this possible?

1. User sends a request to the web server. A direct access to the database is forbidden.

2. The request is sent to the authentication server to be validated.

3. Authentication server provides an access token that can be expired after a short period.

4. Web-server verifies an access token and responds with decrypted data.

i dont understand why you would want to run this in development on digitalocean

currently the way it is, this thing is only available on localhost, on wherever your droplet is being hosted

it's not being exposed to the public

much similar to how a local server works on your pc

just use gunicorn or so

How do I make a subdomain?

[inland oak]

Same A(or AAA for ipv6) record as for main domain

Just instead of @ or www, we write subdomain. Example:

A dev 35.65.56.55 600

[lyric parrot]

hi im trying to run my web in vscode but it wouldn't run it says (Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Manage App Execution Aliases.) so anyone could help me to run it ?

[glacial portal]

Oh wait

How do I connect my website as a subdomain using flask? (In one hosting)

[lyric parrot]

or tell me what should i do

?

[inland oak]

Flask is not the tool to make subdomain.
U just point DNS records to ip server with flask

[glacial portal]

How do I do that then?

[inland oak]

👆

[glacial portal]

Code wise

[inland oak]

U setup DNS settings for your domain

Using GUI in Domain provider
Or terraform / pulumi any other infra tool to do the same as code

[glacial portal]

Oh it's not easy then

[inland oak]

Pulumi has Python support ;)

[glacial portal]

https://www.geeksforgeeks.org/subdomain-in-flask-python/amp/

[glacial portal]

@inland oak

[inland oak]

I explained how to set subdomain for real server.

The guide explained two things

1. how to test domain restricted applications at developer machine (useful)

2. how to have routing at flask application level to handle two domains from same application.(in my opinion that is useless information, because usually we want second domain for second application. I never encountered the need to handle two domains from one application. That is silly and against microservices approach)

Monolith is not the way.

[lyric parrot]

im sure that its not form the pc its form vscode cause i wrote in the cmd and it was all right

[inland oak]

Create venv for your project (from console) at root folder where u open it

And in corner of vscode, select venv path to it, if it was not autselected

In 99.999% cases we don't need vscode access to global python anyway

[lyric parrot]

it tells me the same when i try to make a venv

[inland oak]

The whole purpose of subdomains is to have different application from different IP to it.

If it is the same app. Just use different sub path.

The only case when it is acceptable to direct two domains to one ip... In k8s ingress. And in nginx reverse proxy. Because they both fastly making internal redirects to different apps

[lyric parrot]

i wrote (python -m venv work_env) in the terminal

[inland oak]

Select it at the corner of vscode

Bottom left of right

[serene prawn]

You could do the same using any reverse proxy really, it doesn't have to be hosted in k8s

[inland oak]

I mentioned reverse proxy

[serene prawn]

I thought it was exactly nginx + k8s

😅

[inland oak]

I would have added k8s prefix then ;b

[glacial portal]

I see thanks! But I don't know much about nginx or the other one I'll learn it later!

[inland oak]

I didn't ever use ingress outside of k8s, I wonder if it is possible or it is purely kubernetes native app

[inland oak]

Learn nginx, that would be easier. There is free book about it

[inland oak]

https://www.nginx.com/resources/library/complete-nginx-cookbook/

[serene prawn]

There are other solutions, like traefik 🤔

[inland oak]

They serve different purposes, don't they?

[serene prawn]

If you use nginx solely as a reverse-proxy then not really

[inland oak]

Ingress is for routing
Traffic reverse proxy + advanced caching

Nginx can do caching too though

[serene prawn]

Traefik can do simple load balancing, and caching is only available in enterprise version 🤔

[inland oak]

Nginx gives most of access to caching (part is only in enterprise)

And load balancing is almost fully only in enterprise

Haproxy could work as a free load balancer

Or just to use cloud providers lbs

[sacred crane]

I am doing prediction on a machine learning model using PyTorch and in Django rest framework. while loading I am getting TypeError: 'method' object is not subscriptable error. How to rectify this error. My views.py file

response = {}
@api_view(['GET'])
def result(request):
    solute = request.POST.get['solute']
    solvent = request.POST.get['solvent']
    results = predictions(solute, solvent)
    response["predictions"] = results[0].item()
    response["interaction_map"] = (results[1].detach().numpy()).tolist()
    return Response({'result': response}, status=200)                                                 

class ApiConfig(AppConfig):
    name = 'api'
    MODEL_FILE = os.path.join(settings.MODELS)
    model = joblib.load(MODEL_FILE)  
``` my `apps.py` file

[serene prawn]

You're using dict.get wrong

[inland oak]

.get is function, requires (), not []

[sacred crane]

Then how to change it?

[serene prawn]

Either do request.POST["key"] or request.POST.get("key")

[sacred crane]

do i need to use {}

[serene prawn]

request.POST is a simple dictionary object

the same as {} or dict()

https://docs.python.org/3/library/stdtypes.html#typesmapping

[sacred crane]

  File "C:\Users\MAHESH\Desktop\iiit hyderabad\django rest api\api\views.py", line 384, in result
    solute = request.POST['solute']
  File "C:\Users\MAHESH\anaconda3\lib\site-packages\django\utils\datastructures.py", line 78, in __getitem__
    raise MultiValueDictKeyError(key)
django.utils.datastructures.MultiValueDictKeyError: 'solute' 
```  after changing i got this error

[inland oak]

There is no value with this key I guess

Use get to be not having errors if there is no strict need to have it, optionally provide default value
Or try catch error and do what needs to be done in case it is missing

[inland oak]

Although u know, I am quite sure it is wrong way to address post data in Django

[serene prawn]

Yep, you should be using forms

[inland oak]

I remember they were in dictionary ending with .data

[sacred crane]

I am taking two strings from the user and doing a prediction and sending the results as json using rest api. Is this login justify my code? Do i need to use models?

[serene prawn]

https://docs.djangoproject.com/en/4.0/topics/forms/

[sacred crane]

But it is a django rest api and the frontend side is react.

[serene prawn]

Then use drf

Or other framework like FastAPI, i personally don't really to write api's using django

[inland oak]

request.POST.data ?

[serene prawn]

https://www.django-rest-framework.org/api-guide/serializers/

[inland oak]

Or request.data I don't remember

[sacred crane]

i am trying to integrate celery and redis. I have already written it using flask but unable to integrate with celery so i was shifting to drf.

@app.route('/predict', methods=["POST", "GET"])
def predict():
    if request.method=='POST':
        solute = request.form["solute"]
        solvent = request.form["solvent"]

    else:
        solute = request.args.get("solute")
        solvent = request.args.get("solvent")

    results = predictions(solute, solvent)
    
    response["predictions"] = results[0].item()
    response["interaction_map"] = (results[1].detach().numpy()).tolist()
    return flask.jsonify({'result': response})
``` flask code

[inland oak]

Huh. Celery is agnostic to framework

[serene prawn]

If you're using drf at this moment then you should use serializers to validate and clean your data

[sacred crane]

ok

[sacred crane]

i have problem finding tutorials using flask and celery

[inland oak]

Use official celery docs

They have valid enough getting started instructions

There are no attachments to specific framework

In its original version at least

[sacred crane]

ok

[inland oak]

Even if there is no database interactions?

[serene prawn]

Yep

Serializers != Models

You would still use pydantic models(serializers) in fastapi app, right?

Even if there's no db interactions

[inland oak]

I guess it makes sense. Getting nice inbuilt JSON errors from validators work

[inland oak]

Haven't used FastAPI yet. Going to fix it later

[serene prawn]

Just as an example:

class UserCreateSerializer(serializers.Serializer):
    username = serializers.CharField(min_length=3)

It's guaranteed to be a string, otherwise when doing any operation on something that you expect to be a string you'd just 500:

username = None
username.lower()

[inland oak]

For now all the different DevOps tools consume my time ;)
Going to setup monitoring/logging/autoalerts in k8s next

[inland oak]

Cool. Validator without database usage

I wonder if DRF can catch it

Or without db in drf it would not give error

[serene prawn]

Catch what? 🤔

[inland oak]

That it is a string or not

[serene prawn]

It would, you should just create your serializer and validate it

from rest_framework import serializers

class CommentSerializer(serializers.Serializer):
    email = serializers.EmailField()
    content = serializers.CharField(max_length=200)
    created = serializers.DateTimeField()

serializer = CommentSerializer(data={"some": "data"})
serializer.is_valid(raise_exception=True)

[inland oak]

Let's assume that while not tested it is not guaranteed in drf ;)

[serene prawn]

Wdym it's not guaranteed?

[inland oak]

Okay, I did not see it ;)

Thanks

I can see now

[serene prawn]

I meant that if you're not using drf serializers and just accessing request.POST["something"] it's not guaranteed to be of the type you expect or be cleaned (e.g. trailing/leading whitespaces)

[inland oak]

I did not see before usage of serialisers alone without model

That is why was doubtful

[serene prawn]

Yep, there's ModelSerializer but if you expect some data to be in your query for example you could create a serializer for it

[inland oak]

I see no problems here.
Query URL data can be accessed in same dictionary way as post data

[serene prawn]

I know that drf has built-in pagination, but it's just an example:

class Query(serializers.Serializer):
    page = serializers.IntegerField(min_value=1, default=1)
    page_size = serializers.IntegerField(min_value=1, max_value=1000, default=100)

def some_view(request):
    query_serializer = Query(request.params)
    query_serializer.is_valid(raise_exception=True)
    query_data = query_serializer.validated_data

Not all of your data would come from db, you might call other services, so using something like django-filter is really meaningless here

[sacred crane]

class Prediction(serializers.Serializer):
    solute = serializers.CharField()
    solvent = serializers.CharField()
``` I have created serializer now i want to use this serializer inside views how can i use it?

response = {}
@api_view(['GET'])

[serene prawn]

You probably have to use an APIView
https://www.django-rest-framework.org/api-guide/views/

[sacred crane]

but i am already using @api_view(['GET]) ??

[serene prawn]

Yep, you just need to use your serializer then, usually they're stored in separate module (e.g. serializers.py),

@api_view(['GET'])
def result(request):
    serializer_in = serializers.Prediction(data=request.data)
    serializer_in.is_valid(raise_exception=True)
    data = serialzier_in.validated_data
    
    response = {}
    results = predictions(data["solute"], data["solvent"])
    response["predictions"] = results[0].item()
    response["interaction_map"] = (results[1].detach().numpy()).tolist()
    return Response({'result': response}, status=200)

I just always used class-based views 😅

<div class="owo">
<div class="uwu">

is owo the parent and uwu is child?

Or this isn't a relationship?

[inland oak]

it depends on closing elements

<div class="owo">
  <div class="uwu">
  </div>
</div>

in this situation uwu is child of owo. and owo is parent of uwu.
uwu is content of owo

<div class="owo"></div>
<div class="uwu"></div>

in this situation they are both elements of the same level. childs of smth.
and both empty in content

I am struggling with my Flask SQAlchemy query. I have categorized articles. I can query the articles easily enough and get their associated categories. My problem is doing the reverse -- query the category and retrieve associated articles.

The following is from my models

`class Category(db.Model):

__tablename__ = "category"

id = db.Column(db.Integer, primary_key=True)
slug = db.Column(db.String(64), index=True, unique=True, nullable=False)
name = db.Column(db.String(128), nullable=False, index=True)

categories = db.relationship(
"Category",
secondary=article_categories,
lazy="subquery",
cascade="all,delete",
backref=db.backref("articles", lazy=True),

class Articles(db.Model):

`
and from my view

@artitcle.route("/category/<category_slug>", methods=["GET"]) def by_category(category_slug): category = Category.query.filter_by(slug=category_slug).first_or_404()

I can retrieve the category but I cannot retrieve the associated articles. Is there something missing from my model?

[serene prawn]

Could you send code of both of your models again?

[fickle mantle]

`class Category(db.Model):

__tablename__ = "category"

id = db.Column(db.Integer, primary_key=True)
slug = db.Column(db.String(64), index=True, unique=True, nullable=False)
name = db.Column(db.String(128), nullable=False, index=True)

article_categories = db.Table(
"article_categories",
db.Column("article_id", db.Integer, ForeignKey("articles.id")),
db.Column("category_id", db.Integer, ForeignKey("category.id")),
)
class Articles(db.Model):
categories = db.relationship(
"Category",
secondary=article_categories,
lazy="subquery",
cascade="all,delete",
backref=db.backref("articles", lazy=True),

__tablename__ = "articles"

id = db.Column(db.Integer, primary_key=True)
user_id = db.Column(db.Integer, ForeignKey("users.id"), nullable=False)
uuid = db.Column(db.String(36), index=True, unique=True, nullable=False)
title = db.Column(db.String(180), index=True, unique=False, nullable=False)
released_at = db.Column(db.DateTime, nullable=True, index=True)

categories = db.relationship(
    "Category",
    secondary=article_categories,
    lazy="subquery",
    cascade="all,delete",
    backref=db.backref("articles", lazy=True),
)`

[serene prawn]

Use a codeblock

[fickle mantle]

I have been trying to figure out how to do that i discord.

[serene prawn]

@fickle mantle Why your categories relationship is in Category class though?

[fickle mantle]

It actually is not. That was pasted by accident. I updated the models here

I have checked my models, everything looks fine.

I am using Django rest framework to do prediction on two strings and using celery to run inference. But I was unable to make use of celery workers even though I have done everything perfectly. I am getting predictions from drf only

I am using redis as a broker.

My tasks.py

@shared_task(bind=True)
def predictions(self,solute, solvent):

    mol = Chem.MolFromSmiles(solute)
    mol = Chem.AddHs(mol)
    solute = Chem.MolToSmiles(mol)
    solute_graph = get_graph_from_smile(solute)

    mol = Chem.MolFromSmiles(solvent)
    mol = Chem.AddHs(mol)
    solvent = Chem.MolToSmiles(mol)
    solvent_graph = get_graph_from_smile(solvent)
    delta_g, interaction_map = model([solute_graph.to(device), solvent_graph.to(device)])
    return delta_g, torch.trunc(interaction_map)

#My `views.py`  
@api_view(['GET'])
def result(request):
    response = {}
    solute = request.GET.get('solute')
    solvent = request.GET.get('solvent')
    results = predictions(solute,solvent)
    response["interaction_map"] = (results[1].detach().numpy()).tolist()

    response["predictions"] = results[0].item()

    return Response({'result': response}, status=200)

I guess the problem is not adding .delay() to results = predictions(solute,solvent) but if I add results = predictions(solute,solvent).delay() I am getting error.

Even though I am getting my prediction perfectly without any error their is no celery task is running please help me where I am doing wrong

[native tide]

idk bro vsc sucks

undefined doesnt matter

if works

[whole garnet]

from flask import Flask

[native tide]

ignore undefined

doesnt matter if works

[lyric parrot]

yeah there isnt any error in the code but i can see the result

cant

[hollow minnow]

what npm package do you need? is there a python alternative?

[whole garnet]

remove

I was curious if whether having cloud serve act as my database for the iot system can affect the system's performance?

because I was using mongodb, but only realized that it can only store the images in a string type unlike cloud server which you can see the images taken from the iot directly from the server.

[robust folio]

i wann a know how it works

and what is it

which tool to use

everything

[manic garnet]

there is no tool for that

[robust folio]

phishing sitE?

[manic garnet]

u gotta know ethical hacking and cybersec stuff to setup your own tools

[robust folio]

ik preety much abt it

[manic garnet]

and this is not the channel to talk bout that

[manic garnet]

what do u know bout it

[robust folio]

no dont need to explain every thing

jst important points

[manic garnet]

it ain't working that way

u have to learn it in detail

[robust folio]

jst tell me surfacely

[manic garnet]

as far as I think u r trying to phish someone and kid this ain't the place to talk hacking stuff

don't send me reqs

[robust folio]

this ain't the place to talk hacking stuff so i send u req

[manic garnet]

no i don't accept strangers reqs

[robust folio]

ok

[manic garnet]

u gotta search on the topic

[robust folio]

anyways its web development

[manic garnet]

and learn with a structure

[robust folio]

did a lot reacearch bwt not satisfied

so i came here

to get some knowledge abt it

[manic garnet]

tell me what u did

and maybe u wanna know more bout it so talk in #cybersecurity

[robust folio]

i searched but, what I found was there is like the victim(who is going to be hacked ) should also provide
authentication to get hacked

and i wanna know can some one get hacked by just clickng a link

[manic garnet]

yes they can btw

[wheat verge]

how to deploy django app the easiest way?

[manic garnet]

use heroku

[wheat verge]

and why cant we deploy it in netlify?

[manic garnet]

or the best is pythonanywhere.com

[robust folio]

bwt what?

[manic garnet]

sorry man never heard of it

[wheat verge]

ok thanks

[manic garnet]

u can use pre built Kali Linux tools

idk if they are available on github or not

[robust folio]

such as

[manic garnet]

I don't remember the name I'm not a cybersec guy

but u can use it to clone webpages and host it

just like make a fake LinkedIn page and host it

And send it to someone and if someone enters their credentials to login u get what they entered which is the their credentials

[robust folio]

this has been sick nowadays

everyone is aware of it

and i was taking abt hacking systems not linkden acc

[manic garnet]

it's hacking bruh

it was an example man

[robust folio]

ik it

[manic garnet]

it's kind of not easy to hack into systems

u have to either setup a malware or a backdoor u developed physically in a system and get access

[robust folio]

i jst wanna know is how is it possible to get hacked by jst clicking to link and not doing any thing else

[manic garnet]

it ain't possible

it is never possible

unless ur very trained and can code tools that can make this possible

[robust folio]

no i read an article at morning

it was about RAT link

[manic garnet]

if yes then do what it says

u still will have to get the malware in the victim's phone somehow

and if it is successful u have the access to the system

[robust folio]

it was like getting a malware in browser and if victim closes the browser then u will be no longer getting information

[manic garnet]

idk bout that bruh

[robust folio]

its form quora

[manic garnet]

u read the edit part

[robust folio]

but it is possible he said
