Anyone has experience building small real-time web apps and has suggestions for libraries to use when async operations are needed + with a mix of API's ? Am I good to go with FastAPI + python-socketio + asyncio ?

Got a Selenium project I'm working on but after a while the webpage decides to hang and needs the driver resetting. What's the best way of handling it, just a try except catching a TimeoutException and calling a method from there to reset the driver?

#

hey y'all if someone of you knows a little bit about APIs, could maybe have a quick look at #help-grapes ?

#

I do not understand why my code enters the if statement even though the response code is 200?

Have a issues with celery+flask
I have celery work fine on its own but when I add it to a flask app. it does not parse the url correctly and tries to connect to localhost.
The only way I was able to get it working was to call Connection directly.

from flask import Flask
from celery import Celery, shared_task
import ssl

app = Flask(__name__)

url = 'amqps://user:pass@host:5671'

app.config.update(
    CELERY_BROKER_URL=url,
    CELERY_RESULT_BACKEND='rpc://',
    BROKER_USE_SSL={'cert_reqs': ssl.CERT_NONE},
    CELERY_TIMEZONE='UTC',
    CELERY_DEFAULT_QUEUE='TEST'
)

    celery = Celery(
        app.import_name,
        backend=app.config['CELERY_RESULT_BACKEND'],
        broker=app.config['CELERY_BROKER_URL']
    )
    celery.conf.update(app.config)

    class ContextTask(celery.Task):
        def __call__(self, *args, **kwargs):
            with app.app_context():
                return self.run(*args, **kwargs)

    celery.Task = ContextTask
    return celery

celery = make_celery(app)

    with Connection(hostname=url,
                    ssl={'cert_reqs': ssl.CERT_NONE}, default_channel='test_ext') as conn:

        result = addCall.apply_async((a, b), queue='TEST', connection=conn)

Also change the port at the top to 5672

to run rabbit in docker:
docker run -d -p 5672:5672

or if you don't have docker installed then:
sudo systemctl start rabbitmq.service

hmm

#

could my_ext_caller not be collecting the promise and so you don't see it's error?

#

I'm not 100% on the behavior of apply_async in kombu

#

but that implies it's returning a promise. and then you immediately close without collecting it

#

whereas the decorated task is actually getting the result?

#

so they're both failing but you only see one of them failing?

#

o nvm I missed task_ignore_result=True in that decorator

hmm

#

does task.delay() ignore the ignore_result=True setting?

#

the documentation I linked up there implies that task.delay does not allow extra execution options

#

possibly including ignore_result=True

#

if you change delay to apply_async do you still see the error?

#

and/or the other way around

#

that's the only difference b/w the endpoints I can see

#

they're calling the task with different methods

fervent jungle
#

it never get to that part. It was throwing this before
WARNING: No hostname was supplied. Reverting to default 'localhost'

with the .delay

idk. perhaps your CELERY_BROKER_URL is malformed

#

I'm not familiar with amqps

fervent jungle
#

it works out side of flask

I've always used something like CELERY_BROKER_URL = "pyamqp://user@host"

Django messages multiple tags
I was trying to pass multiple extra tags in the messages.add_message() as a list. It seemed to work fine while using render, but when I'm trying to use redirect, it passes the extra_tags as a string and I can't get my objects by indexing as it considers the whole list as a string. Is there a way to solve this or pass multiple extra tags? Here is the code-

def handleSignup(request):
    if request.method == 'POST':
        username = request.POST['signup_username']
        name = request.POST['name']
        password = request.POST['signup_password']
        email = request.POST['email']

        if User.objects.filter(username=username).exists():
            messages.add_message(request, messages.INFO,
                                 'Please try another username.', extra_tags=['danger', 'Username already taken!'])
        elif User.objects.filter(email=email).exists():
            messages.add_message(request, messages.INFO,
                                 'An account with the email already exists.', extra_tags=['danger', 'Email already in use!'])
        else:
            user = User.objects.create_user(
                username=username, email=email, password=password)
            user.name = name
            user.save()
            messages.add_message(request, messages.INFO,
                                 'Account created.', extra_tags='success')
    else:
        return HttpResponse('404 -  Not Found')

I had an issue with my django form coming up as unbound after passing request.POST to populate its fields. my init contained an argument list, and I appear to have resolved the issue by removing the argument list and setting it to just (self, *args, **kwargs) then calling super().init(*args, **kwargs). Does anyone know why that is?

Hey guys, I'm not a web developer at all, so I apologize if this seems pretty basic but, in a website if I see:

#A bunch of code then:
    </div>
<script type="text/javascript">
#a function
</script>
</div> 
#end of the greater block I'm referring to in my question

Does that mean that that function only applies to the information within that greater <div> </div> block?

        {% for row in json_data["data"] %}
          <tr>
            <td>{{ row['col1'] }}</td>

# cerulean thicket when i remove try catch then it works

(o_O) okay. then try:

        json = ({
            "status": "failed",

                })
                # in the below try catch we are accepting values from request 
        try:
            country = data["country"].upper()  
            print('country=', country)
            batch_size_val = (data["batch_size_val"])
            epoch = data["epoch"]
            epoch_val = epoch
        except KeyError as error:
            print(error)
            print(json)
            logger.debug(json)
            return(json)

cyan valley
# cerulean thicket on postman i am getting this

it's hard to debug the code in it's current state because it's failed somewhere in function.

you are using data keyword even after extracting data from it. gotta replace the use use of data variable after the first try catch and use they variables you created in the try catch.

            batch_size_val = (data["batch_size"])
            epoch = data["epoch"]
            epoch_val = epoch
        except KeyError:
            print(json)
            logger.debug(json)
            return(json)


        # in the below try catch we are validating country name with country code
        try:
            country = pycountry.countries.get(alpha_3 = data["country_code"].upper()).name.lower()
            logger.debug(f'country1 : {country}')
            country = country.split()
            country =("_".join(country))
            logger.debug(f"country : {country}")
            alpha_2 = pycountry.countries.get(alpha_3 = data["country_code"].upper()).alpha_2
            logger.debug(f"alpha_2 : {alpha_2}")
        except AttributeError:                
            jsonify1 = {
                        "status": "invalid",
                        "message" : "Invalid country_code"
                        }
            print("invalid country_code")            
            logger.debug(jsonify1)
            return jsonify1        
        
        try:

            batch_size_val = int(data["batch_size"])
        except ValueError:
            jsonify1 = {
                "status": "invalid",
                "message" : "Invalid batch_size"
                }
            logger.debug(jsonify1)
            return jsonify1

you see you're getting data from the data variable in first try catch so use those variables from first try catch in following try catch instead of using data variable again. it will make the code easier to work with and easier to debug.

i am using pycountry library to to get country name , in that i need country code

cyan valley
#

you can do country = pycountry.countries.get(alpha_3 = country).name.lower() because you already created a country variable in first try catch which has that data.

#

i mean you don't need to do like this. this just makes the code easier to debug

Wait nevermind. Yeah

I have a html page with multiple input images like this:

<form method="POST">

  <input type="image" src="{{ card_path }}" name="{{card_name}}" alt="{{ card_name}}" style="width:100%">
{% endfor %}
</form>

But in my flask app i cannot see which one of the image inputs were pressed. Normally with an input type submit you can specify the value of the button, then see what the value of the pressed button is. But it seems you can't set a value for an input type image.

How can i figure out which one of the images has been clicked?

eternal kestrel
#

but what doesnt make sense is

#

there other item in my json is there

#

there is json["data"]

#

but thjeres also

#

json["count"] which is an int

#

it works

cyan valley
#

Check if you are sending data to the template

eternal kestrel
#

data is an array of dictionaries

cyan valley
eternal kestrel
#

json_data["data"] is the array in the json that contains the items im iterating over

#

I guess I'm not accessing the json properly?

#

or my loop

#

{% for row in json_data["data"] %}

# 
{
    "count": 1,
    "data": [
        {
            "col1": "sample1",
            "col2": "sample2",
        }
    ]
}



          {% for row in json_data["data"] %}
          <tr>
            <td>{{ row['col1'] }}</td>
            <td>{{ row['col2'] }}</td>
          </tr>
        {% endfor %}

How can I modify this to work

Hi I’m curious why are there classes created in the views.py file of a Django project?

unique shore
#

They are functions that take and return web requests

native tide
#

Thanks. I’m trying to figure this first step. What does it mean and what am I doing?

IMG_1118.jpg
#

This is from tutorial

unique shore
#

must be new

native tide
#

What does the context part mean?

unique shore
#

It should work the same way

#

Prolly has to do with the current thing you are editing

#

You can add your own implementation of get_context_data

#

But by default it adds the object being displayed

native tide
#

So I’m calling the function out when I mention m “RED” in the base.HTML file in the case mentioned above.

unique shore
#

Well look at the comment to the side

native tide
#

I wrote those look

#

Lool

#

Oh yea it does so RED is a variable name to call the function

Is there a way I could have 2 options for adding data to django models? one is manually enter the data in the fields or another option is to upload the csv file
Like a OR option type of thing?

var randomNumber1 = Math.round(Math.random()*5+1)
var randomNumber2 = Math.round(Math.random()*5+1)

var dice1RandomImages = listOfItems[randomNumber1 - 1]
var dice2RandomImages = listOfItems[randomNumber2 - 1]

function winner() {
  document.querySelectorAll(".img1").setAttribute("src", dice1RandomImages)
  document.querySelectorAll(".img2").setAttribute("src", dice2RandomImages)

  if ((randomNumber1 > randomNumber2) == True) {
    document.querySelectorAll("h1").innerHTML = "Player One Wins!"
  }
  else if ((randomNumber1 < randomNumber2) == True) {
    document.querySelectorAll("h1").innerHTML = "Player Two Wins!"
  }
  else {
    document.querySelectorAll("h1").innerHTML = "Draw, Roll again"
  }
}

And in my html code i put the js script code link near the bottom of body like

<head>

I’m getting a 404 error. Django tried to use URL patterns admin/ and Calc/ and didn’t match any of these. What could be the reason?

#

What is the main reason for 404 error?

unique shore
#

404 not found means that the page wasn’t found

dim rover
#

what page are you trying to get to?

native tide
#

Interesting I looked at urls and doesn’t seem to find no error in what I type

#

To a page calcs.html

#

Surely admin.html will work. That’s standard?

unique shore

native tide
#

Saved and retried.. same response

do you have a view for calcs/

Star / Wildcard imports

Wildcard imports are import statements in the form from <module_name> import *. What imports like these do is that they import everything [1] from the module into the current module's namespace [2]. This allows you to use names defined in the imported module without prefixing the module's name.

Example:

>>> from math import *
>>> sin(pi / 2)
1.0

This is discouraged, for various reasons:

Example:

>>> from custom_sin import sin
>>> from math import *
>>> sin(pi / 2)  # uses sin from math rather than your custom sin

• Potential namespace collision. Names defined from a previous import might get shadowed by a wildcard import.
• Causes ambiguity. From the example, it is unclear which sin function is actually being used. From the Zen of Python [3]: Explicit is better than implicit.
• Makes import order significant, which they shouldn't. Certain IDE's sort import functionality may end up breaking code due to namespace collision.

How should you import?

• Import the module under the module's namespace (Only import the name of the module, and names defined in the module can be used by prefixing the module's name)

>>> import math
>>> math.sin(math.pi / 2)

• Explicitly import certain names from the module

>>> from math import sin, pi
>>> sin(pi / 2)

Conclusion: Namespaces are one honking great idea -- let's do more of those! [3]

[1] If the module defines the variable __all__, the names defined in __all__ will get imported by the wildcard import, otherwise all the names in the module get imported (except for names with a leading underscore)
[2] Namespaces and scopes
[3] Zen of Python

dim rover
#

so calcs/* is supposed to go to this one thing ?

unique shore
#

import the specific view

#

the urls.py for calc should be something like:

urlpatterns = [
    path(‘calcs/something/‘, views.your_view).
]
#

you can change the import to from . import views and prefix your views in the path with views.

native tide
#

Surely import * will just import everything

#

I don’t have to specific

dim rover
#

oh dont you need a default route

unique shore
#

^

#

there is no default

#

so maybe do /calcs/ in the url

native tide
unique shore
#

Because it seems like you are on what would be the index

#

And there is no index route from what it seems like

dim rover
# native tide

seems like empty string
path("", CalcView.as_view ... might have been right, there

native tide
#

The tutorial made it empty

#

I followed it and I have done it while empty before

unique shore
#

put a / in the quotes

native tide
#

Ah might be that

#

Let’s see

#

Nope

unique shore
#

something must be fucked up with your routes then

native tide
#

Within command line?

#

unique shore
#

#

native tide
#

Sure thanks moai 🙂 and greyblue

native tide
#

I changed some of it like static ended with / shown in video.

#

I still get the ‘/‘ error

native tide
#

At the bottom of the page, it tells you how to do it. I think you have to change your settings file

unique shore
#

anchor tag in html?

#

oh proper error web page

#

didn’t see the error thing

#

that’s only there because you are in debug mode

#

you can specify the error and render html templates for it in views file for the app where you wanna do that

# 
def error_404(request, exception):
    data = {}
    return render(request, ‘path_to_html_file’, data)
#

And you have to specify them in the projects urls

#

You’d have to change DEBUG to false also

#

in urls.py: handler404 = 'myappname.views.error_404'

My format is f-strings:

f"3 + 2 = {3 + 2}"

In f-strings, you can insert any expression that does not contain the same type of quotes as your enclosing string (here ") between curly braces to have it evaluated, then turned into a string via str.

The other format is using str.format():

"{:d} {:s}".format(20, "test")

In this way of using format, the letters after the colons specify how it will be displayed. Some options:
:d Number
:s String
:x Hexadecimal
:n Number, but with localized digit separators
:b Binary
:o Octal

#

!d str.format

lavish prismBOT
#
str.format 

str.format(*args, **kwargs)```
Perform a string formatting operation. The string on which this method is called can contain literal text or replacement fields delimited by braces `{}`. Each replacement field contains either the numeric index of a positional argument, or the name of a keyword argument. Returns a copy of the string where each replacement field is replaced with the string value of the corresponding argument.

```py
>>> "The sum of 1 + 2 is {0}".format(1+2)
'The sum of 1 + 2 is 3'
```  See [Format String Syntax](https://docs.python.org/3/library/string.html#formatstrings) for a description of the various formatting options that can be specified in format strings.

Help!!

#

Pls

mortal grotto
#

can i know why we need django or other framewark to create web applications if we can do this with javascipt and why some people use both instead of one and what's the different between them

unique shore
#

mostly because people hate working with JavaScript afaik

#

and WebAssembly exists too

mortal grotto
#

so it means we can use javascript in backend

unique shore
#

you can, with node.js

#

javascript is both frontend and backend'

mortal grotto
#

and why pepole prefer python over java at backend

unique shore
#

python is mainly backend

#

java or javascript?

mortal grotto
#

and can i know why we can not use python in front end

#

is there any way creating dynamic website using only python

unique shore
#

well, web browsers can only read JavaScript. But, WebAssembly exists now so I guess you can create the frontend in languages other than JS

mortal grotto
#

what is webAssembly

#

i have heard about it

unique shore
#

you cna probably use a preprocessor to convert python to js and back

mortal grotto
#

and should we?

unique shore
#

its a binary instruction format that allows you to create web apps in languages other than JS

#

ehh idk

#

i would still learn and use JS if you are doing any web dev'

mortal grotto
#

ohh

#

thnx for clearing

#

my doubts

unique shore
#

once you learn JS though, use TypeScript instead

#

its a superset of JS

#

with type system

mortal grotto
#

ok i will see

unique shore
mortal grotto
#

but i'm confuse right now if i should go for web development

#

i am beginner and know python and tkinter

unique shore
#

also WASM supports:

  • C/C++
  • Rust
  • AssemblyScript
  • C#
  • F#
  • Go
  • Kotlin
  • Swift
  • D
  • Pascal
  • Zig
  • Grain
#

@mortal grotto well think about why you want to program. what do you want to make?

#

don't just do web dev because everyone else does it

mortal grotto
#

idk but i want to go into ML

#

but not confident enough right now

unique shore
#

well then do ML

mortal grotto
#

so i 'm thinking first i should clear some concepts of math and get grasp at programming logic

unique shore
#

yeah prolly

mortal grotto
#

then should jump into ML and stuff

stuck trout
#

@mortal grotto Confidence comes after action, not beofre

unique shore
#

#

if that's helpful...

#

You maybe can try out SimpleTestCase or TransactionTestCase? If you’re careful using them your tests will run much faster since it won’t recreate the entire test database between tests. However this means you have to be more careful not to introduce contamination of state between tests

is rhere anything similar to this for django

i want to build a leetcode clone of sorts but im not sure how i can go aboit running submissions

steel night
#

Uhhh do you care if the result is secure

forest sonnet
#

no

#

i just wanna see it work

steel night
#

Because if no, you can just use ‘eval’ on strings your users submit. If yes, then you’re in for a large amount of complicated engineering effort

forest sonnet
#

not gna be using this for anything other than tht

#

oh wtf

#

i can eval

#

a whole python script?

steel night
#

As long as it’s valid in the current namespace

forest sonnet
#

so if i just ran

#

eval("def solve(i):
return i+1")

steel night
#

Or you could write the script a user submits to a temp file, then run via subprocess ‘Python temp file.py’ and capture the output

forest sonnet
#

itd actually work?

#

ohhhh

#

alr i'll put that into thought

#

that seems like an idea

#

alr tyty

#

can eval run functions or is thst not a thing

#

i dont have my editor with me rn :(((

steel night
#

See the section on “nested locals”. Executing a tempfile may be a more general solution

forest sonnet
#

hmmm i see

#

maybe the tempfile is the way to go

#

is it difficult to run a subprocess

im new w django and i honestly have no idea what im doing

Hi. I have beginner experience in html/css + javascript. wanted to learn python and unfortunately have to make a website + a mobile app - what language would you guys recommend for the front-end?
I'm going into ML hence needing to use Python, but I've heard linking Python to html is not a good idea. I'm also not sure what the best lang would be for mobile dev w/ Python
I'm also going to incorporate NLP and an ML algorithm I don't know yet if that influences the recommendation at all

I'm making an api using drf and using session authentication for the endpoints. While testing the PUT request I noticed that the url was making 5 queries. 1 of them was duplicate.

i have a slightly dumb question -- I am just getting started with django and have built a basic blog with a login, registration, password reset, etc. I'm really enjoying the django interface and would like to use it as my back-end for a web app. I will likely be using React for the front-end design.

However, when someone goes to my website, I want it to first have a typical marketing approach: homepage, about us, FAQ, about us, etc. Then the subscribe/login/get started attached.

For those who have built web apps, but also have a project site built like a regular website -- do you still use django for the whole thing? Or do you, for example, build the site separately and then have it link to the web app django project when users register and login?

For either option: What would you recommend?

Like this? @inland oak Roadmap:

Create project using Django + Django React API ▶️ Build web app inside django project

Using the same back-end, build the company site within the project under its own separate folder directory to hold css templates, pages, etc

Try this.

  1. use a custom hook to handle input
    const [value, setValue] = useState(initialState)

    function handleChange(e) {
        setValue(e.target.value)
    }

    return [value, handleChange]
}```
#
  1. Use the custom hook like this
const [name, setName] = useInput('')
  1. In the form fields
onChange={setName}
#

just make sure you have your button as type="submit in the form

#

I don't think you need to handle onClick directly for submit buttons

#

I could be wrong though

#

in your onSubmit

const dispatch = useDispatch()
const onSubmit = (e) => {
        e.preventDefault()
        const obj = { name, ... } //  Your states
        dispatch(yourFunc()) // if you're using redux you'll need to use useDispatch
    }

I am writing a custom migration in Django. In my operations, I first have an AlterField and second a RunPython which also has a function for reverse_code. When Django reverses this migration, does it run the RunPython operation first?

#

The AlterField is adding a unique constraint. When I revert the migration, I get a unique constraint violation from my RunPython. Thus, it seems RunPython goes first, but it relies on the unique constraint being removed before running.

#

I may try to split AlterField into two operations - one that allows nulls and another that removes the constraint. Then my RunPython should be able to go between I think. Not sure if there is a better way.

steel night
#

What does the the RunPython command do? nvm actually read the snippet

#

But anyway in my experience Django does run the migration operations in the order listed, and in reverse order when running a reverse migration. So I think what you proposed makes sense.

proper hinge
#

Thanks. It turns out I would have had to split it up anyway for other reasons.

#

I needed to implement this as well https://stackoverflow.com/a/1934764 and as per the comment, I need to set null=True and change the field type separately. So I can just apply the null constraint when I change the field type. This has worked for me.

I am kinda good at flask I know how to use it but I want to know about backend web dev and indepht

what should I learn?

inland oak

So, it begins from
System analysis and design to plan your backend

And continues with
OOP, Design patterns, clean code, TDD, DDD and different Robert Martin books

Optionally getting to know Infrastructure as a code at least at minimal level or higher

#

Because backend is quite merged with DevOps/infrastructure
CI CD is included into it

CI/CD

#

you should also know how to make APIs, use cloud services, mess with databases, linux proficiency, etc

#

Be lazy, steal it from bootstrap

#

And? Bootstrap can be still used

#

If u need range spider

#

Or I did not understand what do u mean by range slider

#

Looks like regular slider
Which u can implement
With any frontend means.
On your own
Or by taking from bootstrap

#

It would be easier to implement custom slider in frontend framework

#

But bootstrap should work in backend as alternative

#

Or any other CSS framework

#

Mine too

#

So what is the problem then

#

And

inland oak
#

I have a feeling like u a just missing html/CSS/js basics

#

Perhaps to read it first

#

Then learn js

#

I am lazy to read your code.

I can just say that general idea what u need to do in

Making slider custom or bootstrap.
Attaching yourself with JavaScript event to listen to value of slider changes or drop down mouse thing to finish.

When necessary event happens, u fetch/Axios whatever js request to your API.
Using data u update DOM values.
Client side in backend is painful, u should consider making just post request with full rerender of page (instead of js requests)

Or it can be done in a nice way with frontend framework, which should be needed here to scale the code

#

U have an option to make it almost without js by just making post request for full rerender, but this solution is bad because requires full page rerender

#

And it will be just bad to scale

#

In reality you need frontend framework here, like react/Vue to make it beautifully easy

#

It will be brain dead simple to implement there

#

U can implement what u wish with just vanilla js/jQuery but in my opinion those tools should not be used in 2022 year unless absolutely necessary

#

U will need to learn vanilla js anyway, in order to understand what u a doing in frontend framework

#

At limited level sufficient to use frontend framework for small projects

ok so I'm working on a website that allows for users to share images to people in their friends list, the functionality to share images, is that you have a form that takes in an image and you have an element where you select all the friends you want to share it with.

#

how would I store this in the database so for any given user, I can query all the posts that they have created and all the posts that have been shared to them

inland oak
#

Feel free to create any other alternative schemes, that's just as first suggestion

native tide
#

so if I created a post and shared it with 3 friends, we would have to create three sharing_links "objects" if you will

inland oak
#

Feel free to send Queries in Bulk method, so you could send it in one request to database instead of multiple ones

Hey guys! I'm working on a simple API to learn how to work and develop it. This is a no-name restaurant order and I'm not sure how to build the json array correctly:

    "products": {
        "product":{
            "_id": "asdf1",
            "name": "Burger menu",
            "addons": "",
            "price": 12.99,
            "currency": "EUR"
        },
        "product":{
            "_id": "asdf1",
            "name": "Chicken burger",
            "addons": "Spicy sauce",
            "price": 6.99,
            "currency": "EUR"
        }
    }
}```

For sure I have duplicate `product` key in here + how could I get all prices from here to sum it up?
#

I have idea for products

{
    "products": {
            "ids": 
                {
                  "asdf1",
                  "asdf2",
                  "asdf3"
                 },
        }
}

But I'm not sure how to add here the rest of the details like name, price etc in here

Hi! I'm trying to learn Flask so I've been playing with it and reading about the last couple of days. Now I'm doing a personal project to get my hands dirty. My ideas is to make something similar to smallpdf.com. A site that lets you upload stuff, process it, and then serves it back.

I can already let the user upload the files and I know how to serve them, but I’m wondering if I’m building it in the correct way.

My idea was to give the user a session id so I can serve them back their own processed file and not mix them up (if someone else is using the webapp at the same time) then deleting both files so as to not run out of space.

I wonder if anyone has a video or a guide that builds a site kinda like that so I can compare. I feel I would build it in a way that’s not flask-y

#

I don't know if I can link to a pastebin to give a better idea of how I've been building it so far

hi guys, quick question: how do files get uploaded to s3? Im using django storages and facing problems uploading large files. do the files go to the server first them s3? or directly from client to s3?

inland oak
#

So obvious thing to do would be, uploading to server first and from it to S3 bucket

#

But at the same time, this creates doubled traffic and the biggest concern about it is TRAFFIC LIMITS which are charged for you

#

I know that DigitalOcean is not charging for transfers to S3 bucket from servers located in the same LOCATION as S3 bucket

#

which eliminates the problem

hello
not sure this is the best channel for this question, but:

I'm trying to retrieve the url to an image from the COCO dataset (for instance, https://cocodataset.org/#explore?id=216739)
the issue is that this image is loaded dynamically/takes a while to load (javascript? dunno!);

I've tried using urllib and requests, but cannot get the HTML with the full content (or, at least, the url of the image, http://farm3.staticflickr.com/2794/4190008256_fb66764971_z.jpg)
I've checked for solutions online, nothing worked; I don't want to use selenium
suggestions?

# topaz widget Why don't you want to use selenium? This is the tool for the job.

unnecessarily complicated for what I need
I'm able to use the cocoapi that has been written in Python, but for that I need to download a 240MB ZIP file with the image annotations
unfortunately they didn't write an API where I can simply input 'image ID' (an integer like 216739) and get the image back
I also saw that the package 'requests-html' exists... but not for Windows

#

hi

#

ok question

#

if I pass a multiform data to a python backend

#

(like this react example)

# 
  const createUploadForm = () => {

    console.log('value of uploadFile: ', uploadfile)

    var formData = new FormData();
    formData.append("image", uploadfile)
    const obj = {title: postcomment.title, content: postcomment.content}
    const json = JSON.stringify(obj);
    const blob = new Blob([json], {
      type: 'application/json'
    });
    formData.append("document", blob);
    return formData
  }

  useEffect(()=>{
    var formdata = createUploadForm()
    if(postcomment.submit){
      // axios.post(
      //   "http://localhost:8000/lightone/comment/1/", 
      //   {title: postcomment.title, content: postcomment.content}
      // )
      axios({
        method: 'post', 
        url: "http://localhost:8000/lightone/comment/1/", 
        data: formdata
      })
#

how would I decode this on a python backend?

#

there are a bunch of mediocre solutions I found on the net that might work, but there should be a straightforward solution

#

is there anybody here?

A REST API doesnt necessarily have to return a response in json?
A REST API could also return response in XML?

native tide
rigid laurel
#

Technically yes, but at this point rest is pretty synonymous with JSON over http

naive rock
#

Yeah that's what I thought too that JSON is synonymous with REST.

We utilize a third party API and they said they were changing API from SOAP to REST and I was relieved that I wont have to deal with XML anymore. I can directly with json. I made request to their new API and it still returns XML lol.

But I understand a lot of people have XML in their codebase, so they likely didnt want that to get effected.

rigid laurel
#

If someone said they were moving from soap to rest but still had most everyone returning xml I would feel thoroughly cheated

native tide
naive rock
#

I dont know why I never thought of this before, but XML looks a lot like HTML.

I'm new to python web development. How would I make a input, so they can input a string, send it to my server, and I return the string, after processing it with my already written code to modify the string?

If you only need to process one string at a time, a single GET endpoint should do

Is it possible to write code for a dynamic website in 5 days?

#

Only front-end code

inland oak
#

Is it going to be one page of content, with something like 4-5 blocks of unique stuff? All right, possible.

#

Is it going to be 2 pages, out of 2-3 blocks? All right still possible

stoic marsh
storm stag
#

no

#

use your own web framework, nah

inland oak
storm stag
#

use others web framework, hell yeah

#

😎

inland oak
#

if blocks are reusing same CSS, then they can be considered as the same

#

we count only UNIQUE CSS blocks

#

blocks with same applied CSS, can be not counted

#

if you have 6 pages with 2 blocks out of ALL of them UNIQUE. You are highly likely will not be able to do it in 5 days. At least 3 times more better to ask time

native tide
#

which front end framework would you recommend to use with django as back end and how do the two interact with each other ?

inland oak
#

if you are ready to jump to TypeScript and wishing Google ecosystem, with hard learning curve: Choose Angular

#

if you are ready for Facebook ecosystem, the most popular frontend framework in the world, starting from just Javascript, choose React

#

if you are wishing the most simple to learn frontend framework, with ecosystem more or less rich as Angular, but not afraid that it came from China. Choose Vue.js

#

I tried Vue.js so far pithink

#

I would not mind trying React in the future

#

And at the same time keep in mind that scaling code is a bit difficult thing to do. If you are in Vue.js, make sure your project is relatively small. Or otherwise you could out grow your State management system

#

for bigger in code projects perhaps React or Angular could make a better choice

#

Vue.js is nice and simple choice for small projects

native tide
#

So all of these are usable with django without an issue ?

#

Sorry if this is a dumb question

#

but the way we are being taught is basically, they give us computers and a project and tell us : Do it, you have 6 months

inland oak
inland oak
#

so it is not for serious production?

native tide
#

yes basically but it is actually a serious production

inland oak
#

erm. okay. Then React or Vue.js if it is intended for serious production. Angular is an option too, but I would exclude due to harder learning curve.

native tide
#

I think we'll use react then, seems straightforward enough for our current level

inland oak
#

i would look first at getting Router and State management
And thinking, do I need Internationalization tool?

#

Oh, and how to have Unit Testing

#

Since i am newbie to it, I would have checked those tools that make initial setup to add all tools for me (Create React App? pithink )

#

of course I could not live without SCSS, CSS without SCSS is plainly horrible

#

I would learn as first thing, how to DRY/split/reuse my code into smaller components of course

#

Due to me being a book person, I would be tempted to get a book pithink

hi

#

Hi

delicate ore
#

do you want to give data?

#

or receive it

eternal kestrel
#

im posting it with requests library and receive with flask.request

#

two python apps

delicate ore
#

so an API?

eternal kestrel
#

yes

#

forwarding the request

delicate ore
#

ok what do u want

eternal kestrel
#

from user to site to api

# 
r = requests.post(API_URL + route, data=data, files=files, headers = {'Content-type': 'multipart/form-data'})
#

I have this

#

data is a dict

#

json

#

files is a dict of the file upload

#

so { filename : file }

#

theres 2 in it

#

it works fine i think

delicate ore
#

is it working?

eternal kestrel
#

the issue is data

#

heres the problem

#

on the API side when receiving

#

if I use

#

request.get_data()

#

it says

delicate ore
#

maybe try request.data, and print it to see what happens

eternal kestrel
#

same as get_data but

#

json.loads(get_data()) returns: UnicodeDecodeError: 'utf-8' codec can't decode byte 0x89 in position 1108: invalid start byte

#

well request.get_data()

#

and

#

request.get_data() without json.loads gives this error:

#

TypeError: byte indices must be integers or slices, not str

#

when I try to access an item in the json

#

with data["item"[

#

]*

#

when I do

data = request.get_data()
print(data)
#

its a massive byte array

#

OH

#

I see

#

my json is there at the top

#

after the json its the file data as bytes

#

i thought flask seperated that

#

the problem here is request.files is in request.data after my specified data

#

how can i get around this

delicate ore
#

request.data.data

eternal kestrel
#

no way

#

let me try

agile pier
eternal kestrel
delicate ore
eternal kestrel
#

hmm, youre right

delicate ore
#

decode(request.data, "utf-8")
Then to str

eternal kestrel
#

Right, the problem with decoding

#

same problem as get_json

#

it decodes as utf8

#

invalid bytes

#

on the file data

#

its not a string

#

its filestroage

#

not json

#

darkrex

eternal kestrel
#

its not pretty though

delicate ore
#

also ping me when u reply

#

use request.files

eternal kestrel
#

@delicate ore hello

#

        'photo2': ('photo2', photo1.stream(), 'application/octet'),
    }

or the exact same without .stream()

#

photo1 and photo2 are the user uploaded files from flask request of type FileStorage

Hello, I am currently working on an API using Flask, flask-resplus, Werkzeug, and a couple other less relevant packages. So flask-restplus is a little outdated and the newest version of Werkzeug breaks it: https://github.com/noirbizarre/flask-restplus/issues/777 so I downgrade it to what it should be, 0.16.0 or something like that right. And now the program gets broken again because Flask wants the current version of werkzeug: https://github.com/pallets/werkzeug/issues/2324. What is the work around for this? I've never had dependent dependency issues such as this one lol

django, flask, fastapi are the big 3 web frameworks

#

django is a jumbo-framework. It has pretty much everything.

#

flask is slimmed down without as many features, but still useable.

#

fastapi is the minimal required for making a REST api, but also supports other features if additional libraries are installed. Templates are supported if jinja2 is installed. Static files can be used if aiofile is installed. etc

#

flask uses werkzeug, while fastapi uses starlette as a wsgi/asgi implementation
