#

lemon_thinking Thanks it worked but in documentation is mentioned as one of the way to enable token authentication REST_FRAMEWORK = {}

inland oak
#

why this thing is superrior to standard debug?

rocky ferry
#

i don't know

inland oak
#

I thought there is no better debug than unit testing

i'm watching his tutorial

#

erm, ok. probably something I don't know then

sick glacier
#

@inland oak :in settings disable auth
REST_FRAMEWORK = {} disabling works but what if i want to test it using the authentication token enabled

inland oak
#

which uses django rest framework test api client

#

or you could even test with request library, if test api client will be bypassing authentication

#

testing in postman is highly unefficient, unproductive and slow method 😉

#

it has its uses from time to time though

Ok I am working with django-admin and have a situation where I want to create Model A and Model B (which has a OtO relationship with Model A) using the same django-admin page. So I have a ModelAdmin for ModelA that has an inline for ModelB. But when I hit save Nothing is created for ModelB...

#

I dug around a bit, and it looks like I might have to overwrite save_formset but I am having trouble getting the data from the inline form from formset so I can actually use it.

Hello guys, i kinda need a little help, i'm working on a tool with flask, and i splited my webpage into 2:
-nav bar and form
-datatable and search bar which i load via a javascript function
The probleme is i dont know how to send datafrom the form to flask without reloading the page, then i load the datatable ?
Or how can i also get data into my js script from the form before the page reload or redirect ?

naive blaze
#

Thanks i'll check it out !

dapper lichen
#

@naive blaze something like this:

<form id="the_form">....</form>
<button onclick="update_view()">Update View</button>;``` ```js
function update_view(e){
  e.preventDefault();
  const form = new FormData(document.getElementById("the_form"));
  fetch("/update_view", { method: "POST", body: form })
    .then((response) => response.json())
    .then((data) => update_the_page_with(data));
}``` ```py
from flask import jsonify
@app.route("/update_view", methods=["POST"])
def update_view():
    new_data = do_something_with(request.form['param1'])
    return jsonify(new_data)```
naive blaze
#

@dapper lichen in your case the update_view() does not reload the page ?

#

or it will just show an empty page with the new data ?

dapper lichen
#

no, it just returns some json data (assuming new_data is a dict)

#

you update only what you want with some "update_the_page_with" JS function

naive blaze
#

Thats great ! i think i start getting it, i'm a need to try

#

Thank you !!

dapper lichen
#

@naive blaze updated above

naive blaze
#

The page i need to update the data in is loaded via javascript

# 
function load_home() {
     document.getElementById("table_div").innerHTML='<object type="text/html" data="compact-table.html" style="width: 1810px;height: 1500px;" ></object>';
}```

def index():
    if request.method == 'POST':
        files = ...
        transferable_files = map(lambda file: base64.b64encode(file.read()).decode(), files)
        return render_template('index.html', files=transferable_files)

HTML Code

{% for file in files %}
    <img src="data:image/png;base64, {{ file }}">

Does anyone know how to make a token without accessing a route
For example in my application of two types of user. Client user and admin user. both the client token and the ADM token are able to access all end-points
How do I make the client's token not be authorized in the user's route

inland oak
#

JWT tokens allow storing dicts jsons in it

# 
{
  "admin": true
}
#

just store in it

#

and make a decorator that extracts this information and forbids non admins

@admin_only

I'm using Flask
I'm doing it like this: create_access_token(identity=cli.cli_id,fresh=False, expires_delta=timedelta(days=90))

Hi @humble vortex I just found your message I noticed that sergeyklay has made his own release, please let me know when you see this message. I'd like to prevent having too many "same packages". One of the options I can think of right now is to move your project under https://jazzband.co/

make in python API web framework exposed API end point

which you can request with GET or POST request (whatever you need, the difference is little)

you will call it with javascript, while inputing necessary variables

i'd need to set-up a python API endpoint first

it will activate python script to call your sql for server query

and as result, saving it into image

and give link to it in API answer ;b

that's actually quite simple. it just sounds hard.

I'm going through a secondary Django tutorial and I've been using Django to create a new app so I can follow a tutorial where the author is creating drop-down menus for a site.

However, I'm having trouble with a simple import statement

#

This is my directory structure

unknown.png
#

I created an app called testing within the project dropsite

#

within urls.py I'm trying to import the contents of dropsite.testing.views but I get errors when I try the python manage.py migrate command

#

My error is ModuleNotFoundError: No module named 'dropsite.testing'

#

This is how I'm trying to import my views, but I've clearly bungled it

unknown.png
#

This may not be web-development specific, but i'm using Django to create the app and I'm new to it. How would you guys recommend I fix my import command to get the classes within views

opaque rivet
sly adder
#

That was another issue

#

I have since figured it out, thankfully 😄

#

Sorry I didn't post here

#

I'm very new to web including Django and HTML

opaque rivet
#

nice, keep it up 🙂

sly adder
#

My goal in the near-term (this week) is to create a very very basic site that I can run locally

#

all it will have is drop-down menus with selections, and then a button that says "run" so I can do some work behind the scenes and then display a graph

opaque rivet
#

sounds good

sly adder
#

But I also know zero HTML

#

Is there a resource that allows you to modularly build HTML?

#

For instance just stacking input forms or am I thinking down the wrong path with regard to creating the Django app?

opaque rivet
#

well, HTML modular-ly builds your page. I'd recommend you just learn it, it's quite simple and compared to python doesn't take long to learn.

sly adder
#

Gotcha

#

Aside from "Google: how to create input forms with HTML" is there a decent place to start?

#

I guess I also need to look more into Django forms to understand how they fit in with everything

#

Like if I can splice Django forms with other elements

opaque rivet
#

its different for everyone, but I prefer courses where you do projects and learn by doing... I recommend codecademy's html course and iirc it's free

sly adder
#

That sounds good

opaque rivet
#

and yeah you can also use django forms, it's just a way to produce HTML forms with python

sly adder
#

Ah

#

That would probably be easier to pick up

#

I was just looking at this example form


from django import forms
from .models import Person, City


class PersonForm(forms.ModelForm):
    class Meta:
        model = Person
        fields = ('name', 'birthdate', 'country', 'city')

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.fields['city'].queryset = City.objects.none()

        if 'country' in self.data:
            try:
                country_id = int(self.data.get('country'))
                self.fields['city'].queryset = City.objects.filter(country_id=country_id).order_by('name')

            except (ValueError, TypeError):
                pass  # invalid input from the client; ignore and fallback to empty City queryset

        elif self.instance.pk:
            self.fields['city'].queryset = self.instance.country.city_set.order_by('name')
#

It seems relatively intuitive, but it has some database terminology that Django utilizes which is a little new to me

tough lintel
#

@sly adder netninja always has a great tutorial

sly adder
#

Awesome, I'll check it out

#

I think I kind of missed the point of Django forms though

tough lintel
#

Doesn't use any css framework IIRC

sly adder
#

I think I can do most of what I want with Django forms then I'll have to figure out a way to generate and display a graph based on data

tough lintel
#

I'm new to django too.

sly adder
#

Seems awesome tbh

#

Just a big learning curve

glossy arrow
#

yeah, Django has somewhat of a learning curve

sly adder
#

Well I've used sqlite databases in projects before

#

But I've done everything so manually that this just sort of blows my mind

#

@glossy arrow how long have you been using Django?

glossy arrow
#

I haven't done much Django really, I read through the tutorial, and I did a few stuff with it, but I prefer frameworks like FastAPI or Starlette

sly adder

Ah gotcha

I got this error relate to Base64 on my crud

This is my core\users\login.py :

    return {"message": "User found"}

and api\crud.py :

def get_Login(db: Session, username: str, password: str):
    db_user = db.query(models.UserInfo).filter(
        models.UserInfo.username == username).first()
    print(username, password)
    pwd = bcrypt.checkpw(password.encode('utf-8'),
                         db_user.password.encode('utf-8'))

For displaying graphical data?

#

showing post request but not the data

sly adder
#

Good to know

vestal hound
#

I mean

#

it's doable with HTML

#

so if you want it to be static

#

that's fine too

sly adder
#

I still have other issues pre-graphical data display

#

Like right now I can't get my model choices to populate in a drop down menu

#

😢

vestal hound
#

and verify that there actually is data in the body

vestal hound
sly adder
#

Yeah

vestal hound
#

are you using ModelForm

sly adder
#

I have all the choices defined in models

#

Yes

#

But quite honestly I don't understand the structure of ModelForm

vestal hound
#

you want a ChoiceField

sly adder
#

I'm trying to modify a tutorial for dynamic drop-down

#

Oh not forms.Select() ?

vestal hound
#

well

#

it depends

#

what are you trying to do exactly?

sly adder
#

Honestly just input some very basic personal data

#

Right now it's simply Name / Age / Race

#

Building off this HR input form example

vestal hound
#

then Select should be fine

sly adder
#

So I will say that I don't understand the structure and I'm not very knowledgeable on super().__init__() calls like this example used

#

So I tried something as simple as this

from django import forms
from .models import Person, Race, Age

class PersonForm(forms.ModelForm):
    model = Person
    fields = ('name', 'race', 'age')
    name = forms.CharField(max_length=100)
    race = forms.Select(choices=Age.AGE_RANGES)
    age = forms.ChoiceField(choices=Race.RACE_CHOICES)
#

Sorry, one moment.

#

This was my forms definition, but it didn't create anything because it says I have no model class defined

#

Then I converted it to this structure, though I can't say I know 100% what the def __init__() and accompanying super() call are accomplishing here.

from django import forms
from .models import Person, Race, Age


class PersonForm(forms.ModelForm):

    class Meta:
        model = Person
        fields = ('name', 'race', 'age')
        name = forms.CharField(max_length=100)
        race = forms.Select(choices=Age.AGE_RANGES)
        age = forms.Select(choices=Race.RACE_CHOICES)

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
vestal hound
sly adder
#

nope, but this is my first foray into anything remotely web

vestal hound
#

what do you do normally

native tide
sly adder
#

#

native tide
#

i printed the buffer before sending andit sends

vestal hound
# 
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)

this does nothing

opaque rivet
sly adder
#

Sorry I thought I had that commented out

#

That was from the example

# 

from django import forms
from .models import Person, Race, Age


class PersonForm(forms.ModelForm):

    class Meta:
        model = Person
        fields = ('name', 'race', 'age')
        name = forms.CharField(max_length=100)
        race = forms.Select(choices=Age.AGE_RANGES)
        age = forms.Select(choices=Race.RACE_CHOICES)
#

This is what I had

#

I selected too much

#

And yes I deal with defining classes, class inheritance, and utilizing class structures to create separate modules, etc.

I'm certainly not an expert, most of my class definitions and program structures are probably relatively simple.

#

So this is what I get with this selected,

unknown.png
#

But my choices aren't being populated

#

It's just the initial placeholder value of "--------"

opaque rivet
sly adder
#

Sure

#

I'll just show you my models definitions

# 

from django.db import models


# class for defining the race model as an input form with beginning set of limited choices
class Race(models.Model):
    RACE_CHOICES = (
        ("B", "Black"),
        ("H", "Hispanic"),
        ("W", "White"),
        ("O", "Other")
    )
    name = models.CharField(max_length=20)
    race = models.CharField(max_length=1, choices=RACE_CHOICES)

    def __str__(self):
        return self.name


# class for defining the age model as an input form with comprehensive age list
class Age(models.Model):
    AGE_RANGES = (
        ("1", 'Less than 21'),
        ("2", '21, 25'),
        ("3", '26-30'),
        ("4", '31-35'),
        ("5", '36-40'),
        ("6", '41-50'),
        ("7", 'Greater than 50')
    )
    name = models.CharField(max_length=20)
    age_range = models.CharField(max_length=1, choices=AGE_RANGES)

    def __str__(self):
        return self.name


# Person class defining a model comprised of the other models for the database relationship using
# Foreign Keys for Age and Race
# --> This section will be expanded as new variables are progressively added.
class Person(models.Model):
    name = models.CharField(max_length=100)
    race = models.ForeignKey(Race, on_delete=models.SET_NULL, null=True)
    age = models.ForeignKey(Age, on_delete=models.SET_NULL, null=True)

    def __str__(self):
        return self.name
opaque rivet
#

Try this field:

sly adder
#

I don't quite understand the queryset " A QuerySet of model objects from which the choices for the field are derived and which is used to validate the user’s selection. It’s evaluated when the form is rendered.
"

#

Or is that just the choices?

opaque rivet
#

Oh actually might be the wrong field, queryset is just a list of your database entries. I don't think that's what you want

#

hmm, everything looks right to me

sly adder
#

Yeah I also don't understand why ChoiceField isn't applicable here

#

Do you need to see my views at all?

#

or the HTML templates ?

opaque rivet
#

ChoiceField is applicable

sly adder
#

Right

#

But it still doesn't change the output of the dropdown

#

Which must mean that something else is incorrect with how I've defined views or templates, right?

opaque rivet
#

hmm, the only thing I'd say is that the fields you specify shouldn't be in the Meta class, not sure if that makes a difference though... Apart from that I don't know what could be the issue, I also don't know how django forms represents foreignkeys.

sly adder
#

Should it matter if they are foreignkeys though?

#

I can try to move my field definition elsewhere

opaque rivet
#

I may be wrong but yeah I think it would be an issue... the foreignkey just represents a relationship to another table, it doesn't really give any information about which column you want to mimic as a form field

#

maybe it would be easier scrapping the ModelForm and just building a normal form.

sly adder
#

This was the functional form in the example


from django import forms
from .models import Person, City

class PersonForm(forms.ModelForm):
    class Meta:
        model = Person
        fields = ('name', 'birthdate', 'country', 'city')

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.fields['city'].queryset = City.objects.none()

        if 'country' in self.data:
            try:
                country_id = int(self.data.get('country'))
                self.fields['city'].queryset = City.objects.filter(country_id=country_id).order_by('name')
            except (ValueError, TypeError):
                pass  # invalid input from the client; ignore and fallback to empty City queryset
        elif self.instance.pk:
            self.fields['city'].queryset = self.instance.country.city_set.order_by('name')

Of course this accomplishes more on the city and country fields

#

And this gave functional dropdowns

#

But I've tried to modify the variables that I'm attempting to collect from the user and progressively redefine the models, views, forms, etc.

opaque rivet
#

do you have the source code for the Person model?

sly adder
#

The original?

#

Or mine?

opaque rivet
#

the one from that example

sly adder
# 
class Person(models.Model):
    name = models.CharField(max_length=100)
    birthdate = models.DateField(null=True, blank=True)
    country = models.ForeignKey(Country, on_delete=models.SET_NULL, null=True)
    city = models.ForeignKey(City, on_delete=models.SET_NULL, null=True)

    def __str__(self):
        return self.name
#

So their dropdown selections were city and country which were both ForeignKey's

opaque rivet
#

Ok, so turns out Foreignkeys are represented by django.forms.ModelChoiceField so you can give them a queryset (a list of database entries) for the user to pick

#

but in your case you just want the user to pick a choice, right?

sly adder
#

Yes

#

I just wanted all selections to be available

#

And to select. I know it's dumb that I choice a more involved drop-down menu Django example and tried to manipulate it to suit my purposes

opaque rivet
#

if you're using a ModelForm you can also hop into the python terminal, initialize it and repr(form_object) to see its fields

#

Ok, so have you saved any db entries into your other models?

sly adder
#

Yes

#

two

#

Just have dummy names right now because after migrations I have not been able to get my fields displayed correctly and I stripped all of the existing fields that the example utilized

opaque rivet
#

hmm, so I don't think the ModelForm will suit you then. Person has Foreignkey fields which are django.forms.ModelChoiceField and you'll have to pass a queryset attribute to give it choices to pick from (but these are queryset - the user picks entries in the db which isn't your use-case)

#

Honestly I would just build a normal form with choicefields

sly adder
#

Ok

opaque rivet
#

nice and simple

sly adder
#

So scrap ModelForm all-together?

opaque rivet
#

yeah, I think the form should be simple enough to just use forms.Form

#

with a few choicefields

sly adder
#

Getting some errors after I redefined my forms to this

# 
from django import forms
from .models import Person, Race, Age


class PersonForm(forms.Form):
    model = Person
    fields = ('name', 'race', 'age')
    name = forms.CharField(max_length=100)
    race = forms.ChoiceField(choices=Age.AGE_RANGES)
    age = forms.ChoiceField(choices=Race.RACE_CHOICES)
#

return form_class(**self.get_form_kwargs()) TypeError: __init__() got an unexpected keyword argument 'instance'

#

now I think it's my views

opaque rivet
#

yeah forms.Form doesn't take model or fields

#

you just define the fields

sly adder
# 
from django.views.generic import ListView, CreateView, UpdateView
from django.urls import reverse_lazy

from .models import Person
from .forms import PersonForm


class PersonListView(ListView):
    model = Person
    context_object_name = 'people'


class PersonCreateView(CreateView):
    model = Person
    form_class = PersonForm
    success_url = reverse_lazy('person_changelist')


class PersonUpdateView(UpdateView):
    model = Person
    form_class = PersonForm
    success_url = reverse_lazy('person_changelist')
#

So you're saying remove model and form_class in each view class here?

opaque rivet
#

just remove:

model = Person
fields = ('name', 'race', 'age')

from the form

sly adder
#

oh nevermind

#

yeah

the program send data to register and receive response and then quickly send to /tasks

opaque rivet

#

but when i remove print(request.data.decode('UTF-8')) in web_task_beacon()

the first function doesn't print anything

sly adder
native tide
#

but when i dont remove it is printing perfectly

#

why so?

sly adder
native tide
#

i removed the print from second function and first function is not printing anyting, same happen with second function

#

if i remove print from first function, 2nd function doesn't print anything

#

because it is single-threaded?

#

it is printing when i add this line: jdata = request.get_json(force = True)

Does anyone know what is a good way to host a flask server? I was interested in hostinger shared hosting, but their shared hosting doesnt support python. Does anyone know if their cloud hosting (https://www.hostinger.com/cloud-hosting) does? Or should I use something like digital ocean?

#

Im fine with using vps' I just want something powerful and scalable, with a nice UI (preferably)

#

I recently deployed a Flask app using AWS App Runner. It's a pretty stripped down version, so it's easier to use. It can deploy a container or create one for you from a GitHub repository. You can manage it from the AWS website. Probably also works through CLI but I never bothered setting that up.

A similar service would be Google Cloud Run. These work well if you only have one app you need to deploy and you don't need a lot of detailed configuration.

cerulean badge
#

a silly question but would you prefer mdbootstrap templates or from colorlib?
if you don't want to spend money.

grim elk
grim elk
#

What does CLI mean

#

Sorry like I said im new to web development

#

I know how flask and WSGI works but other then that I don't know much to do with deployment

proper hinge
#

CLI = command-line interface i.e. a tool you interact with through your terminal/command prompt as opposed to a GUI (graphical user interface, such as the AWS website)

#

Yes, AWS App Runner is managed. You just give it a container and it takes care of pretty much everything else. It can automatically deploy for you when your code changes. It performs health checks. It can automatically scale up the number of instances running. It load balances for you. There's probably more stuff I am missing.

#

If you didn't know, by container I mean like a Docker container.

#

And if you're daunted by Docker containers, they have an alternative where you just give them a GitHub repository and it will create a container for you.

It also gives you a domain (though not a pretty one)

Has anybody encountered issues with JWTs?

The title of link "Is anyone here good at Flask / Pygame / PyCharm?"

the text

There are two problems with this question:

This kind of question does not manage to pique anyone's interest, so you're less likely to get an answer overall. On the other hand, a question like "Is it possible to get PyCharm to automatically compile SCSS into CSS files" is much more likely to be interesting to someone. Sometimes, the best answers come from someone who does not already know the answer, but who finds the question interesting enough to go search for the answer on your behalf.
When you qualify your question by first asking if someone is good at something, you are filtering out potential answerers. Not only are people bad at judging their own skill at something, but the truth is that even someone who has zero experience with the framework you're having trouble with might still be of excellent help to you.
So instead of asking if someone is good at something, simply ask your question right away.

The point is that asking 1. Can I get help or Is someone good at X? is pointless. it takes time and attention. Like now I had to explain to you why you got the reply you got.

I havent used it yet, but definitely can see how it would be beneficial. Because I'm working with some api, that returns a lot more than what I need.

So is there a way to tell if something is REST or GraphQL?

sonic crater
#

Anyone use flask?

bright mason
#

Yeah

sonic crater
#

I'm not even sure how to ask my question so I'm just going to delete everything and try again haha sorry for bothering you. I may be back when I have a better idea

#

literally that

#

I mean

#

generally a /graphql endpoint is a sign

#

also, most APIs have some kind of documentation

#

e.g. OpenAPI spec

#

which you can consult

is it possible to manually configure the value of sid from client side instead of it randomly getting generated with socket.io Python ?

vernal valve
#

ahh i am newto python from where i should start

grim elk
#

If ur new to python I would start by learning it using someone like TechwithTim's beginner guide

#

If ur new to python web development then I would start by watching a basic flask guide

can you share some code so I can see what's happening?

half patrol
# 
clients=[]

@socketio.on('connect')
def handleclient():
    print("connection")
    clients.append(request.sid) ``` so I did this to store the client's sid when he connects
#

socketio.emit('output',{'data':"hello world".encode("utf-8")},to=clients[-1]) then this to send this client a message using the sid

# 
var socket = io().connect('http://127.0.0.1:5000/stockcurve/{{ id | safe }}/50d/1d');
            
            
            socket.on('output', function bruhhha(msg) {
               console.log('Received message');
            }); ``` and this for the client side
#

the connection is working, but the message is not being recieved by the client

Trying to understand how Steamlit works

#

Looking at the source code, Python calls JS, right?

#

Here's an example

# 
        text_proto = TextProto()
        text_proto.body = clean_text(body)
        return self.dg._enqueue("text", text_proto)

And TextProto is a component:

export default function Text({ width, element }: TextProps): ReactElement {
  const styleProp = { width }

  return (
    <StyledText data-testid="stText" style={styleProp}>
      {element.body}
    </StyledText>
  )
}
#

It's imported like that:

# 
from streamlit.proto.Text_pb2 import Text as TextProto

Hi

#

So I am using an api to get stock prices in python

#

Now I want to use socket.io to use a web socket client

#

So how do I send my json file that I received to my JavaScript server

limpid nacelle
#

can i ask a css question in here too?

#

if yes

#

This should animate it so that the text changes every 10 seconds


#home .content h1::after{
    content: "cool";
    animation: textanim 10s infinite linear;
}

@keyframes textanim{
    25%{
        content: "A developer";
    }
    50%{
        content: "A programmer";
    }
    75%{
        content: "A student";
    }
}

altho it doesn't do that it just stays static at the "cool", any fix on this?

#

this doesn't work

#

it doesn't animate anything

#

Not really a web dev question but if I have a lot of different routes in a flask-app and I want to move them to a different script, what's the best approch? Import them to my main script and then use app.add_url_rule Or maybe first create the app=Flask() and then import so the app.route can be used accordingly. Both just seem very messy to me and keeping it all in one script isn't any better either

hi

#

how are you i´m new programmmer

sly adder
#

any django people online?

#

I'm having some difficulties with forms

split steeple
sly adder
#

Linking functions to buttons

#

Right now I have a very simple app

unknown.png
#

I have race / age / name entry

#

I have code behind the scenes that will calculate a prediction when it receives the race / age values supplied through this form based on statistical data, etc.

#

I would ideally like the "Predict" button to retrieve the current values input into the form and then execute my code for calculating the prediction and then update the form "Prediction" as shown in the picture above

#

@split steeple

split steeple
#

Can I see some of the code you're using?

sly adder
#

Sure, what would you like to see?

split steeple
#

Also if I may ask, what sort of predictions is this app meant to make?

sly adder
#

It's applying a machine learning model based on statistics

#

The prediction isn't relevant to the problem I'm experiencing

#

I can already successfully generate the predictions based on the ML model

#

I just can't tie it all together

#

It's based on publicly available data

#

What code you do want to see?

#

Forms ? Models? HTML templates?

#

Views?

split steeple
#

Views

#

Please

sly adder
#

So this is where I tried to define my function

lavish prismBOT
sly adder
split steeple
#

Alright the views look fine

sly adder
#

Ok

split steeple
#

When you say "can't tie it all together", do you mean it won't display what a user inputs?

sly adder
#

I'm trying to attach that gather_data function

#

to the "Predict" button

#

And then generate the value

#

Based on the current form input

sly adder
#

So I want to press "Predict", then I want to execute the gather_data function, then I will complete my calcs and subsequently send the result back to update the prediction field of the form

#

If it's easier to create another simplistic HTML template to display the result that's also fine for the time being

split steeple
#

Could I see the form?

sly adder
#

the HTML template responsible for the form or the forms.py content?

# 
from django import forms
from .models import Person


class PersonForm(forms.ModelForm):
    class Meta:
        model = Person
        fields = ['name', 'race', 'age', 'prediction']

        name = forms.CharField(max_length=100)
        prediction = forms.CharField(max_length=50, required=False)
#

Here's what I have defined as my PersonForm

split steeple
#

HTML form

sly adder
# 
{% extends 'base.html' %}

{% block content %}

<h2>Personal Information Form</h2>

<form method="post" id="personForm">
    {% csrf_token %}
    <table>
        {{ form.as_table }}
    </table>
        <button name="predict" type="submit">Predict</button>
        <button name="save" type="submit">Save</button>
        <button name="reset" type="reset">Reset</button>
        <a href="{% url 'person_changelist' %}">Return to Previous Page</a>
</form>

{% endblock %}
#

So

#

Based on the help from another user, I believe I need to have some action="" definition within the <form method="post" id="personForm"> opening to the form

#

I just don't know how to define the action specifically to the button

#

And if I need to redefine this form template in order to improve the quality of things I have no issue with that

split steeple
#

Yeah, I'm trying to figure it out myself and I'm coming up a bit short

sly adder
#

no worries

#

I think the easiest route is to direct everything to a new URL

#

something called results.html

#

That just displays a number which is the value

#

But I still don't fully understand the form action

split steeple
#

Yeah, go ahead and try that

#

although

sly adder
#

Yeah I'm just confused lol

split steeple
#

as far as the HTML you posted goes, only thing I notice wrong is that "post" isn't in all caps, unless that doesn't matter(never did it without using all caps)

sly adder
#

Idk if I would need to update urlpattersn

split steeple
#

if you're going ahead and adding the results.html template then yes

sly adder
# split steeple if you're going ahead and adding the results.html template then yes

So don't know if you're still interested, but I achieved the functionality imperfectly.

(1) I had to define the action attribute for the form and direct that to a URL
(2) I had to create the simple results.html template to display the value
(3) I had to update the url patterns for the new add/results/ page
(4) had to fix a lot of my data gathering from the forms within my gather_data function

and probably a few more things lol

position: fixed always in the same place; even if the page is moved
position: absolute positioned to its ancestor; moves along with page movement
position: sticky stays on top, or the same place even when scrolled
width: x changes the width of an element

is flask good enough for large-scale chat apps or do I need something heavily async like express (nodejs) or phoenix (elixir)

quick cargo
# violet briar is flask good enough for large-scale chat apps or do I need something heavily as...

Well Discord's api is built on Flask so the answer is yes, its fine.

Virtually all modern frameworks will give you more performance than you will ever need / never be the bottle neck.
Yes some frameworks are faster than others but generally this is completely overruled by things like waiting on IO, databases etc... as soon as you get to any sort of large scale or ever small scale the framework is generally never the bottleneck

violet briar
quick cargo
#

no lol

#

The only NodeJS stuff iirc is just the electron runtime the app uses

violet briar
#

oh, okay

#

wait, apparently, they use a modified version of flask, not a normal version

#

I wonder what they modified exactly

#

also, do they use flask for the websockets part as well?

quick cargo
#

no websockets are mix of elixer / erlang and rust i imagine.

#

the 'modified' is using the gevent monkey patching iirc

#

basically monkey patches the existing python setup to act asynchronously without having to really change anything

#

generally very popular in flask setups because it works so well

#

although the recent Flask 2 changes are probably gonna end that

violet briar
violet briar
quick cargo
# 
from gevent import monkey
monkey.patch_all()```
#

thats about all it takes to patch it and make it async

quick cargo
#

Large systems generally dont use one framework or language

#

tends to be alot of micro services

#

websockets are a bitch to scale really so something like erlang or rust with work stealing schedulers make it much easier to scale

violet briar
#

ok, so where do they use flask exactly? do they use it for only some stuff like requesting server info?

quick cargo
#

all of the REST API

#

aka everything you use to make changes to the api, the websocket is generally only receive other than presence so all of the things like messages, reactions, etc.... are all done via the REST api with flask

violet briar
#

oh, so the messages served to me when I visit a channel are requested through the flask API, when the websocket is using elixir?

quick cargo
#

generally the setups are you send stuff to the server via REST

#

and receive stuff via ws

# quick cargo and receive stuff via ws

hmmm, I don't really understand what's happening here
does the websocket notify the client and send the new message info to it, or does it notify the client to just make a new request to the API to refresh messages?

quick cargo
#

it sends the messages to the client via the websocket

#

you -> discord = REST
discord -> you = WS

violet briar
quick cargo
#

no

#

well

#

you can think of it like that yeah

violet briar
quick cargo
#

its pretty reliable yeah, keeps it pretty simple as well

violet briar
#

can't find the page in the api docs that documents how the chat works exactly

quick cargo

its complicated

but you can summarise it like that

also, does the discord client listen on one websocket for every task (e.g private messages, notifications) or does it listen on one websocket that sends it everything?

quick cargo
#

the one connection sends everything

violet briar
#

and, would it be better to use a graphql API for the chat app?

quick cargo
#

you can use it, but probably a little overkill

violet briar
#

I mean, discord didn't adopt graphql because they don't want to maintain 2 APIs, but here I am just starting out so I can choose graphql without any issues, the question is, does it scale better with chat apps

quick cargo
#

discord dont use graphql

violet briar
quick cargo
#

and graphql is just alot of extra work

#

for something that doesnt need it

#

the REST api overall is very simple, there isnt a large amount of dynamic things you can change as part of the query

#

Graphql is great for large complicated apis where you can change and filter many many things

#

but using it on a simple structure tends to be overkill / needlessly add the requirement for clients to use it

violet briar
quick cargo
#

I dont see how graphql helps that at all

#

other than use unnecessary bandwidth

violet briar
#

I think it'd help with that as the client will be able to get everything it wants in one request instead of making many requests to many endpoints

quick cargo
#

sure but then what you're doing is increasing the time it takes to send one request massively

#

rather than having several smaller requests which can be done asynchronously of each other

violet briar
#

hmmm, so graphQL won't really help that much, but, can I also use it just for the sake of gaining experience with it?

quick cargo
#

sure

violet briar
#

I think I've never built a real graphQL api before

#

hm, okay, I think I got the tech stack for the project laid out
flask with graphene for the API
nodejs with socket.io for the websockets
react for the front end with relay
mongodb for the database

How can I just make a thing where it redirects you to a website.

thorn igloo
#

can't you do that where you bought the domain?

native tide

idk

Hello! What's the point of Redis, Celery and Flower altogether in a Python web app?

#

Allow better services?

opaque rivet
#

@native tide you can return a 301 response and include the Location header with the url to redirect to

#

@surreal portal
Redis - noSQL db in memory, fast reads/writes
Celery - async scheduled tasks, replacement to cronjobs

surreal portal
#

Interesting

hey everyone hope you're doing fine

make sure the folder also exists

in django how do i make it so some pages can't be accessed once the user has logged in

desert estuary
#

fileupload is in thee

versed lotus
#

the one it mentions in the error message: C:/Flaskiproject/fileupload\CV.pdf

desert estuary
#

idk how to do it ahahah im following the tutorial form the flask docs and still a pain in ass

versed lotus
#

make sure C:/Flaskiproject/fileupload exists, and is written exactly like that

desert estuary
#

C:\Users\Hamza\Desktop\PFA\Flaskiproject\fileupload
actually that's the absolutepath but i don't wanna do it that way since if i gave it the absolute path how it would do in a server

#

since in a server C:/Users/Hamza doesn't exist

versed lotus
#

well that doesn't work then of course

#

you can figure out where the path is, or what's more common: have different configuration files for local testing and on the server

#

usually you wouldn't even have uploads be stored in the project folder, but somewhere outside. perhaps, depending on if it should be downloadable later, in a directory the webserver is going to have access to

desert estuary

wait i kinda get it idk if this will work on the server as well

Hello guys, working on simple django project, but have a trouble.

Im parsing data from API, then store it to DB, and from DB i must send it to template.

But i must send 50 objects so even in JSON it sends as LIST of DICTs, and im really confused by it.

def read_db(offset):
    conn = None
    try:
        conn = psycopg2.connect(host="localhost", database="crypto", user="postgres", password="admin")
        cur = conn.cursor(cursor_factory=psycopg2.extras.RealDictCursor)

        cur.execute(f'SELECT * FROM main_block OFFSET {offset} LIMIT 50;')
        fetch = cur.fetchall()
        dic = {}
        data = []
        for i in fetch:
            dic['hash'] = i['hash']
            dic['height'] = i['height']
            dic['timestamp'] = i['timestamp']
            dic['miner'] = i['miner']
            dic['transactioncount'] = i['transactioncount']
            data.append(dic.copy())

        return json.dumps(data, separators=(',', ':'))

    except (Exception, psycopg2.DatabaseError) as error:
        print(error)
    finally:
        if conn is not None:
            conn.close()```
#

thats how i get data from DB

example of Data that i got:

[{"hash":"384f3e42b8e26443bc1087a0387827146a41f9d3ef663a7d7eda82c927e78bf2","height":"315012","timestamp":"1624372128","miner":"BTJi34JG4dmL5GbTYgDdp8Nyb7Mhpsd1az","tr

15008","timestamp":"1624371648","miner":"BTJi34JG4dmL5GbTYgDdp8Nyb7Mhpsd1az","transactioncount":"2"}]```

and strange thing that it type is STR
```<class 'str'>```
#

some ideas how to send it to Template?

rotund harness
#

Is the data type string?

opaque rivet
#

you can just deserialize your data:

data_array = json.loads(json_string)

Then you can loop through data_array in your template

#

also, what's your project about? data is interesting.

Transcrypt (https://www.transcrypt.org/) translates Python to Javascript for use in the browser

Transcrypt - Python in the browser - Lean, fast, open!

The Transcrypt Python to JavaScript compiler makes it possible to program lean and fast browser applications in Python. Transcrypt applications can use any JavaScript library and can also run on top of Node.js or be used in combination with Django.
