[autumn hedge]

@slow gazelle if you type pip --version in whatever console. it will tell you which python version is in use

[slow gazelle]

i found the error now, I'm starting the app the wrong way

[autumn hedge]

for me its this

[native tide]

hey, im trying to host a flask webapp on docker is there a hosting provider yall recommend that isnt expensive?

[slow gazelle]

i'm using this one to start my app, for some reason, even i activate the pipenv shell in the terminal, that start button is not working

but when i type py app.py then it works

[grand harbor]

uninstall that code runner its annoying

[twin rampart]

im using python and selenium. My problem is that this for loop isnt running, he comes through the if loop but not continues the for loop...

      for multiple_tasks in driver.find_elements_by_xpath("//div[@color='" + listed + "']"):

the weird thing is, that this is working perfectly on other loops, but not here

[ivory bolt]

AWS maybe?

Digitalocean is good too

[ivory bolt]

are you sure you've selected the right element?

security is BIG in django

mainly the fact that it creates so much stuff for you is insane in itself

[dusk portal]

@ivory bolt oh

Hmm

Kinda complex but not hard

1% more complex then flask

[twin rampart]

Yeah, its weird, my code gives the hex ouput „#ff4002“ but the website wants the hex „FF4002“, it took me way to much time

[native tide]

i dont have a creditcard, i tried AWS, but i needed to add a creditcard

[native tide]

gonna check that one out thanks!

[amber harbor]

pythonanywhere.com is easy if u r a beginner.. vultr is good

[native tide]

pythonanywhere doesnt support docker right?

[amber harbor]

right

[ivory bolt]

isn't that a good thing?

[dusk portal]

@ivory bolt good but
Can u guide me sometimes i have done docs that 8 parts

[chilly falcon]

anyone interested to learn django together ??

[ocean notch]

i'm down

how does it work? lol

[ocean notch]

im transitioning from frontend lets do it

[chilly falcon]

Ok bro

Check dm

[runic sparrow]

small insignificant question, but does anyone know PyCharm gave this .py file a "dj" icon?

I'm assuming it has something to do with django

but I'm working on Flask...

[languid beacon]

where can i ask js questions

[runic sparrow]

in one of the off-topic channels, or in a server that has JavaScript help

[calm plume]

Here is fine

Assuming it's related to web dev

[runic sparrow]

What is the purpose of a wsgi.py file for Gunicorn? Can you not just use the app.py file itself?

[ionic idol]

can someone help me with drf-yasg - Yet another Swagger generator?

[stoic lark]

guys can anyone tell me how to clone 1 website if i like theme ?

[ivory bolt]

python apps decide which protocol to use depending on the file names, either as wsgi or asgi applications

asgi would be your async related stuff, while wsgi is sync, standard http

[ivory bolt]

i can help

[ivory bolt]

how do you need me to guide you

what all have you done

[chilly falcon]

Yep

[dusk portal]

@ivory bolt i will tell what i have done from where
U tell me what to do next
How
From where and help me if i have doubt or any error plz

[ivory bolt]

alright

I'm not overly experienced with django, but I generally have a knack for the

'what to do next' thing

[chilly falcon]

I have learn function base view now i want to learn class base but i can't understand it

[runic sparrow]

wait, so the file name is actually important? I just hand it over to Gunicorn...

[ivory bolt]

alright

[chilly falcon]

Super() ... Is confusing 🤣🤣 dont know about mixin ... Which should i learn first

[ivory bolt]

so class based views are really good when it comes to inheritance, and there are two ways to go about them:

1. Using the generic CBVs offered by django
2. Creating your own

[ivory bolt]

ah I feel you

there are things that you can freely write in function based views that you just can't in class based views

[chilly falcon]

I realy dont get this mixin ... There are lot of stuff going on and dont know where to start..

[karmic flare]

Is it even possible to use websockets for refreshing the content of an iframe?

[languid beacon]

no I just wanted to if anyone can show how to build todo app

[calm plume]

You can ask in off-topic

[ivory bolt]

very much so

for example, you can check out my barebones site that uses a discord widget -- that itself uses async

https://learnencode.herokuapp.com/

[ivory bolt]

it's mandatory to specify, at least for django in that aspect

[ivory bolt]

Mixins basically let you reuse the class via inheritance

[chilly falcon]

Thank bro still confuse i will try to do some stuff with it and if i get stuck i will ask you

[runic sparrow]

I'm not using Django

That's why I'm confused

[stoic lark]

hey guys

can anyone clone this website -? www.faceit.com or can do same with python ?

[dreamy talon]

Why

I hope you’re not trying to phish steam accounts @stoic lark 🙂

[stoic lark]

no no

i will create my own database

i need just running script like this website

people register to my website

and they find match

[dreamy talon]

I gotcha

[stoic lark]

they play on my country gameservers

[dreamy talon]

Cloning faceit would probably be very hard. Maybe something like popflash would be easier

[stoic lark]

yeah

popflash also well

i dont nee tournament etc

[frosty gale]

Why is the color property scratched off under the a.home selector?

[ivory bolt]

yep, noticed that use of decorators!!

[ivory bolt]

Are you familiar with synchronous and asynchronous code?

basically, synchronous code has to make an http request every time a resource is updated -- it will not update on it's own.

Asynchronous code keeps a TCP connection open, where the server could be constantly sending information via some pipeline of sorts -- those are your websockets.

That's why in a messaging app, or an app like discord, you don't need to refresh the page every time the app has new information for you: a message, a server invite, ANYTHING

wsgi is a standard file name that deals with synchronous code

and asgi, async

[runic sparrow]

I still don't understand why it's being labelled as"Django" though.

[ivory bolt]

oh. that's simple

you must have installed an extension for python web development or some icons pack

since django is more recognised

and it is MANDATORY in django to define the wsgi.py file (though that is made for you every time the project is made)

[runic sparrow]

Oh... If I knew that, I probably would've started with Django 😅

[ivory bolt]

No I mean you don't need to

[quasi monolith]

Hi , I want to ask how can I pass the ValidationError messages from my custom validation functions to the template

[ivory bolt]

look there's no such thing as one framework being superior to the other (everything > php)

[runic sparrow]

Is there any point whatsoever in having a wsgi.py file for Flask and Gunicorn? Could I not just use app:app instead of wsgi:app or something?

[quasi monolith]

I want to use the same design for my messages as the design from django forms validation

[ivory bolt]

Well, python app packs are basically designed to see the protocol separately

[ivory bolt]

could you elaborate

[quasi monolith]

I want to use the same design for my custom ValidationErrors as the design which is given from django

Just to pass the message from my validation error to the frontend and to show at the same way as the django error

I can't specify more

[ivory bolt]

just pass it along as context or via an api

[quasi monolith]

Yes but it doesn't look at the same way as the django showing error

doesn't matter I will use HTTP message

thanks anyways

[ivory bolt]

Oh!! That's just a whole lot of javascript on your end

[smoky shore]

im new to coding and want to know how to make a website

[autumn hedge]

@smoky shore
step 1: make an html file named index.html and open in notepad.
step2: type hello world and save the file
step3: double click to open the file in your browser and wallah! you have a local static website

to make it more exciting, follow the django or flask install guide

then take your hello world index.html file and place it inside flask or django template directory.
From there you can configure flask or django to serve that static index.html file.

To make even more exciting you can then start adding css the actual HTML markup. Try using bootstrap css as a starting point.

[smoky shore]

@autumn hedge would u prefer django or flask

[calm plume]

Ehhhhhh

That's not exactly best practice

You should put a tag around "hello world"

[autumn hedge]

@smoky shore Flask!

[calm plume]

Django if you want the full power of a database and many other tools, Flask for a smaller project

[smoky shore]

ok thank you

[calm plume]

Django is a full on web framework, Flask is a microframework

[smoky shore]

i would like to do flask cause im new and want a smaller project

[autumn hedge]

@calm plume the question is for a beginner and I later referred to using HTML markup in a later step

[calm plume]

Ehh, you should still teach good practice from the start

[autumn hedge]

@smoky shore Start with Flask

[calm plume]

That's a wonderful idea

[autumn hedge]

good practice is developed ... not taught

[calm plume]

For the basics of HTML and CSS, Codecademy's courses are rather good

[calm plume]

It's not just good practice, tags are the essence of HTML

[smoky shore]

do i install it in python?

[autumn hedge]

@calm plume yes, but that doesn't help answer the question

[calm plume]

No, HTML is a whole other language that comes with your computer

However, you would install Flask or Django

[autumn hedge]

@smoky shore what are you asking to install?

[smoky shore]

how do i install

[autumn hedge]

yes, Flask and Django are python packages that you will install to your local machine

[calm plume]

@smoky shore I recommend you learn the basics of HTML and CSS first

Otherwise you'll be completely lost

[smoky shore]

ok

do i just watch a video on that

[calm plume]

I learned them from Codecademy's courses, those were good

[autumn hedge]

@smoky shore you can watch videos, pay for online courses, or learn by reading and following docs..its entirely up to you

I learned by reading the docs

[smoky shore]

i would rather take the free rout

can u send some docs in dms if thats possible?

also thanks for all the help

[cursive hazel]

Thanks for the info , I was just about to ask the same question, lol 😂. I will definitely use Flask for a smaller project .

[tall steppe]

Hello, I have a question there is a way to do a "contol S" in a python script? Other than with urllib.request... to save an image on a web browser

[devout coral]

Anyone here pretty familiar with the Django ORM? I need some help.

[vestal hound]

what happened to “don’t ask to ask” 😉

[scenic vapor]

Hey friends, i'm launching my MVP soon. We are testing with 1000 users. Im hosting the front and backend separately on digitial ocean. Will the 5$ droplet for both front and back end be sufficient? It's an ecommerce app

[devout coral]

After getting a model object I want to disconnect it's connection to the db but still be able to use that objects static information from the time it queried the db. Any ideas?

[vestal hound]

HUH.

that's interesting

why do you want to do that

what do you mean by "disconnect"?

by default if everything has been loaded it won't hit the DB any more

if I understand what you mean

[devout coral]

I want have a long running celery task

[vestal hound]

like you need to explicitly call .refresh_from_db()

[devout coral]

But I get max connections when I run a few of those

[vestal hound]

ah

okay

[devout coral]

Yeah, I do this now.

Changing to updating with redis

Pushing updates to redis then having one thing that reads from redis and updates everything as needed.

[vestal hound]

hm I'm not sure if Django will support this easily

[devout coral]

However, I want to access everything like normal as their objects.

When does django "disconnect" an object? I do not seem to find anywhere where that is stated.

[vestal hound]

honestly

I have no idea offhand

I would have to look through the source code

but having a long-lived model instance

is probably not something that is contemplated

and...I don't think each instance holds on to one connection...?

the connection pooling should be handled by the driver

AFAIK

[devout coral]

Like, the idea is get everything from the database and make it static and disconnected from the db. Then when I need to update the database I put something in redis and have another celery task that reads from redis to update the database.

The second part I got figured out

[devout coral]

Well wjem I run 100 of the celery tasks the 101 gets that max connections issue.

[vestal hound]

hm.

I'm actually not sure about this

sorry

[devout coral]

Alright

[mild bridge]

Maybe you could just use the builtin JSON serializer on the model, store that, and immediately do a del instance?

I'm not sure what Django does on model __del__s but I'm fairly sure the DB connection will close once it's garbage collected

[primal thorn]

how do i fix this heroku error, ive tried everything and it dosent work, at=error code=H10 desc="App crashed" method=GET path="/

[opal leaf]

hiiiiiiii

I am pretty good in python and still learning django but I need to training on my skills there's a group or smth can help me?

[devout coral]

You can ask here

So if I have that model object unless I do a refresh_from_db it is not connected to the db?

[vestal hound]

it shouldn’t

[celest sinew]

i need help

[devout coral]

Ok, cool. I need to find exactly when it disconnects and I should be golden.

[devout coral]

What do you need help with?

[celest sinew]

this thing keeps saying:
Ignoring exception in on_message
Traceback (most recent call last):

[devout coral]

Looks like db["envouragements"] is an ObservedList. You need to turn it into a regular list to concatenate.

[dusk portal]

How can i master Django
I have readed those 8 parts but cant so something' like post req and fetching stuff

Can't get that logic

def index(request ,question_id)
    n1=get_object_or_404(pk=question_id)```

[primal thorn]

im using the python auth_views.LoginView.as_view in my projects urls.py for a login, how do i make a custom view where i can pass custom variables to it

[mild bridge]

Assuming you're referring to template vars, you can subclass LoginView and override the get_context_data method to add variables to the template's context

[ivory bolt]

wait then how did you create a polling app?

can I see the project you've worked on

[dusk portal]

@ivory bolt sure

I have done that on project but can't do it on my own project

😭😭

[primal thorn]

i made a custom user model but when i try to make a superuser with my cli it does not hash it
so i cant login to my superuser account
but normally registering works

[primal thorn]

got it, thanks

[grand harbor]

Hey guys, I want to make a lucky draw in my website, First I thought that I should use random to show one random item in the list

but then I thought I should make it like after rolling this many times a probability of getting a good item should be higher

so then i thought that after rolling 9 times the tenth item should be that good item and I make it fixed

but It will become odd that every 10 times you roll the 10th item will be that item

so is there a way to add probability on items like every 10 times you draw you will get that item one time. I hope You are understanding what I am trying to say

[primal thorn]

how do i fix this error, im getting this after i created a custom user model (1146, "Table 'app.auth_user' doesn't exist")

[dusk portal]

<a class="nav-link active" aria-current="page" href="{% url /'app1:index' %}">Home</a>```

def index(request):
    return render(request,'app1/index.html')```

app_name = 'app1'
urlpatterns =[
    path('',views.index,name='index')```

[foggy fiber]

maybe I don't know what I'm talking about but url /'app1:index' probably thinks you're trying to divide

[cloud bone]

anybody can help me for making dynamic database in using django

[dusk portal]

fixed

this was not issue

but tq

[hollow apex]

Hey so

@app.route('/logs')
def view_logs():
    contents = []
    with open('logs.txt','r') as logs:
        for line in logs:
            contents.append([])
            for item in line.split(' | '):
                contents[-1].append(item)


    titles = ('Entered Value','Result','IP','Browser')
    return render_template('viewlog.html',
                            the_title = 'Logs',
                            the_column_titles = titles,
                            the_data = contents)
``` this is the piece of the code

and this is the txt file it reads from

but the problem is

{% extends 'base.html' %}
{% block body %}
<h2>{{ the_title }}</h2>
<table>
    <tr>
        {% for column_title in the_column_titles %}
            <th>{{ column_title }}</th>
        {% endfor %}
    </tr>
    {% for log_row in the_data %}
        <tr>
            {% for item in log_row %}
                <td>{{ item }}</td>
            {% endfor %}
        </tr>
    {% endfor %}
</table>
{% endblock %}
``` with this html code, it does not show any table or any column

see, it is supposed to form a table, im quite sure I have passed all the variables correctly but got 0 idea why it would not work

[cloud bone]

anybody can help me for making dynamic database in using django

[gray falcon]

how can i use variables in python in a html code?

[rugged charm]

i work on django not flask, but i guess u'll have to pass
the_title = 'Logs',
the_column_titles = titles,
the_data = contents
the above variables as a dict

[hollow apex]

nvm I figured it out

programming is so tricky

one little mistype and you have to figure the whole thing out

[hollow apex]

Flask users, is there a way to make an exception and hide an html object from displaying from the main html file from which we extend our templates?

[grand harbor]

use if else and try except thats it

jinja template if else that is

[hollow apex]

so

[hollow apex]

in here, this object ('smallest divisor of a number') and its background are in the main html file

I want to hide it in a specific html file

can you be more specific

[primal thorn]

how do i change the name of the tables so it dosent become like this in my db

[opal canyon]

Hello friends, I am building a website with Django, I decided to create a filter for my items, you can filter items like this: Item.objects.filter(type=item_type), so basically I created an url which takes a slug:item_type, and returns a JsonResponse with the items parsed as JSON.
Then I created an Ajax call in my js file and when I wanted to call the url I keep getting an error:
function filterItemType(type) {
$.ajax({
type: "GET",
data: $(this).serialize(),
url: "{% url 'boring:filter_items' type%}"
The Error:
Not Found: /boring/{% url 'boring:filter_items' type%}
[21/Jun/2021 11:32:54] "GET /boring/%7B%%20url%20'boring:filter_items'%20type%%7D HTTP/1.1" 404 6103

So basically JS is not parsing the Django {% url .... %} 😦 I have no idea how to do it in order for JS to build the route...
PS: I also tried to build the route with the type separated as -> url: "{% url 'boring:filter_items' %}" + "/"+ type;
But it's not working either, same error.

[dusk aspen]

does anyone know why this produces a index out of range error?
return cursor.fetchall()[0][0]
If i were to just print the cursor.fetchall() i would get this: [('admin',)]

[surreal portal]

Do you believe it's possible to make a Colab clone?

Using Jupyter's docker stack?

[solar epoch]

Yeah that's not really possible because the template is rendered on the server side, while the JS is happening on the client side. If you want to do it you would need to hardcode the URL and add the type at the end, depending what the url should be exactly.

[solar epoch]

It might be to do with you calling fetchall() twice rather than the code itself. I think once you run fetchall() the first time, the results aren't available anymore.

[surreal portal]

I suppose models.ImageField doesn't deal with bytearrays of pngs immediately does it?

[solar epoch]

I'm not exactly sure what you mean. ImageField just stores a string with the path to the file, but it does validate that it's an image.

[surreal portal]

After experimenting I decided to put the image directly in a BYTEA field. They show up in DBeaver but if I use ImageField I can extract them like that?

When I use models in the shell, it shows a memory object

<memory at 0x7f5067ca0e80> like so

[solar epoch]

oh do you mean forms.ImageField? For validation?

[surreal portal]

No, I'm trying to show them through DRF

[solar epoch]

Well, what do you plan to display?

some encoded version of the image?

[surreal portal]

"creation_date": "somedate",
                "img": null,

This is what happens when I use a simple serializer.

[surreal portal]

Yeah

[solar epoch]

Ah ok, I'd suggest you use BinaryField then

for your API you could have some explicit conversion function in your serializer to handle the encoding

[surreal portal]

I generated the bytearray using PIL

When I inserted records in the db

[solar epoch]

ok but you're still using Django's models, right?

[surreal portal]

Yeah, for reception

[solar epoch]

well it should be a BinaryField.

For DRF the best thing is probably to write your own serializer field to do whatever encoding you need.

[surreal portal]

So it's a custom field just like vanilla Django?

[solar epoch]

a little different but nothing complex: https://www.django-rest-framework.org/api-guide/fields/#a-basic-custom-field

you should override to_representation() and do your encoding there.

[surreal portal]

Looks quite similar indeed.

Also I've seen a guy implementing methods within the models that takes the image and creates it through PIL.Image. He imported them as a field.

class ProductSerializer(serializers.ModelSerializer):
    class Meta:
        model = Product
        fields = (
            "id",
            "name",
            "get_absolute_url",
            "description",
            "price",
            "get_image",
            "get_thumbnail"
        )

class Product(models.Model):
    category = models.ForeignKey(Category, related_name='products', on_delete=models.CASCADE)
    name = models.CharField(max_length=255)
    slug = models.SlugField()
    description = models.TextField(blank=True, null=True)
    price = models.DecimalField(max_digits=6, decimal_places=2)
    image = models.ImageField(upload_to='uploads/', blank=True, null=True)
    thumbnail = models.ImageField(upload_to='uploads/', blank=True, null=True)
    date_added = models.DateTimeField(auto_now_add=True)

    class Meta:
        ordering = ('-date_added',)
    
    def __str__(self):
        return self.name
    
    def get_absolute_url(self):
        return f'/{self.category.slug}/{self.slug}/'
    
    def get_image(self):
        if self.image:
            return 'http://127.0.0.1:8000' + self.image.url
        return ''
    
    def get_thumbnail(self):
        if self.thumbnail:
            return 'http://127.0.0.1:8000' + self.thumbnail.url
        else:
            if self.image:
                self.thumbnail = self.make_thumbnail(self.image)
                self.save()

                return 'http://127.0.0.1:8000' + self.thumbnail.url
            else:
                return ''
    
    def make_thumbnail(self, image, size=(300, 200)):
        img = Image.open(image)
        img.convert('RGB')
        img.thumbnail(size)

        thumb_io = BytesIO()
        img.save(thumb_io, 'JPEG', quality=85)

        thumbnail = File(thumb_io, name=image.name)

        return thumbnail

[solar epoch]

so what's happening here is that the image isn't saved as a bytearray, it's uploaded through django's file upload system... so the image is generated, converted to an in-memory file and then added to the image field

so the field here isn't byte array or anything, just the path to the file.

and the API is just showing the URLs, not the whole encoded image.

[surreal portal]

Ok I see. Probably because the author wants to get them with axios through his Vue frontend

[solar epoch]

Well, probably they will just be served by the webserver directly I think.

That's much more efficient that storing binary blobs in the database and streaming them out to the server, then to the user

generally you should avoid storing binary data in a database

[violet dock]

anyone?

[desert estuary]

im following this guy and while he does this it feels like something is off like why he does it in terminal instead of the flaskblog module also shouldn't he extract that data from the template

[desert estuary]

idk

[surreal portal]

It's because the database isn't created yet.

With Flask-SQLAlchemy you have to create it manually

He didn't cover an important section from server-db interactions called migrations. You have a separate module handling each change done to your models called alembic.

[opaque rivet]

In data['name'], what is data?

[surreal portal]

data is a dictionnary. jsonify interprets the JSON response as a dictionnary.

[opaque rivet]

well, the issue is that data = jsonify(pricer(sku)) is a Response object which isn't subscriptable, so data['name'] is invalid.
also - pretty sure jsonify serializes the dictionary into a JSON-string instead of the other way around.

Instead of using jsonify(pricer(sku)) just use json.loads(pricer(sku))

can u teahch me webcoding

[gray falcon]

how do i get the value of a textbox using a button in html?

im working with python and html

[surreal portal]

TypeError: 'DefaultAdminSite' object is not callable

Got this while adding the models to django's admin part

oh nvm I forgot register

[violet dock]

it doesnt works

[opaque rivet]

what specifically?

[quick cargo]

ObjectId types are BSON

you gotta either remove the id key from the data

or you use pymongo's helper converter

[violet dock]

del data['_id'] with this?

[opal canyon]

YEah, I realized that, although I founded a solution!!!! 😄 I basically passed the {% url '...:etc' type %} as an argument to the JS function! 🙂

[quick cargo]

that would delete the key which mongo inserts as a object id by default yes

[obtuse sedge]

Hi guys,
Does django provide integration with aws??

[violet dock]

mhm seems like it's not

[quick cargo]

what is your actual code

better than making a guess

[opal canyon]

https://aws.amazon.com/getting-started/hands-on/deploy-python-application/
you mean this?

[violet dock]

i did remove _id everywhere but im still getting it

[opal canyon]

Or you mean an aws bucket and such to storage files only?

[quick cargo]

show your code

and an example mongodb document

[violet dock]

is somewhere wrong here?

return json.dumps(sku_listing) or return x == data

[quick cargo]

and is that where the error arises from

[violet dock]

not exactly

[quick cargo]

what is the pricer function

[quick cargo]

and is sku when you send that post request 5021;6

[violet dock]

yes

i did remove all the _id right?

[quick cargo]

from what i can see

[violet dock]

mhm what is causing it?

[quick cargo]

same error?

can you do print(repr(sku_listings))

[violet dock]

where?

oh nvm

[opal canyon]

Django question: Why, if I render a view from another view, the path does NOT change!?

Im under this path, then I make a "transaction"

[violet dock]

oh found it

but i removed_id in x = mycol...

[quick cargo]

out of curiousity

do "_id": 0 instead of "_id": False

[opal canyon]

When the transaction finished and returns "profile_page_view" which is the view of the SAME page where Im at. the path does not changes...

I end up with this path

Shouldn't the return to "profile_page_view" reset the path?

[violet dock]

isnt it the same thing? lol

[quick cargo]

well mongo only accepts ints for that

so it may be a behavioural thing

[opal canyon]

Why this happens?

[violet dock]

it is still happening on certain sku

[violet dock]

@quick cargo is something wrong here?

[quick cargo]

mmm nothing massively sticks out

[violet dock]

how to add a if statement to check if _id exist or not?

find sku_listing['_id'] and del sku_listing['_id']

does the find works like that?

del sku_listing['_id]``` or this @quick cargo

[quick cargo]

well you could just use dict.pop("key", None) so it removes the key if it exists otherwise does nothing

[violet dock]

so in my case it should be sku_listing.pop('_id') right?

[quick cargo]

you'll need to explicitly add the explicit None in that pop because it key errors without a default

[violet dock]

still getting it but lesser

[dusk portal]

Pycharm
My old love

[quick cargo]

data is apparently a string

[violet dock]

what should i do?

[quick cargo]

I mean that will require a bit more debugging on your behalf

[violet dock]

wdym?

[mystic wyvern]

Do you want to return the path of (profile page view)??

Do you guys know how to serve static files with django using cyber panel?

I used the guide provided https://cyberpanel.net/blog/2019/01/10/how-to-setup-django-application-on-cyberpanel-openlitespeed/

I know when I hosted it with IIS I would need to add a virtual host and put my static files there to be served, but I don't see that option here, and the static files aren't being served

[ocean notch]

Why even when using django rest framework do most companies embed the frontend into django instead of being standalone back and front ends?

[obtuse sedge]

How to integrate my discord to my website??

[inland oak]

probably less effort to know just Django than Django+Frontend framework

a small addition of javascript into django template looks less thing to learn than alternative

[ocean notch]

So if I already know a front end framework it should be fine to have them be standalone

I’m new to django so it’s weird seeing several tutorials use embedding

Almost all of the ones I’ve seen

[inland oak]

👍 it sounds about right.
the only consideration to take when it is appropriate using SSR and CSR frontend perhaps

Django makes SSR by default

regular front end frameworks are usually CSR only

Next.js combines both types at the same time

[ocean notch]

Ahh yes I’d probably use next for Ssr

[inland oak]

it depends on the context of the project

[ocean notch]

Thanks sir

[inland oak]

I will prefer using CSR when possible

because it is faster and easier scalable in my opinion

but SSR sometimes is a must to have

[ocean notch]

Maybe for SEO right

[inland oak]

yup

[ocean notch]

You sound like a full stack?

[inland oak]

when we have a lot of dynamic data, extracted from database

nah, just learning

or more like... I am only responsible for backend
but at the moment partially responsible for front end decisions too, due to imcompetence of our front end person%

[ocean notch]

You were saying

[inland oak]

I am wishing to learn being full stack as soon as possible though

planned already learning materials

to dive into front end)

[ocean notch]

Nice react is fun but I feel easier than backend?

[inland oak]

for example we have web site full of tutorials
which are stored in our database

in order for search engines to index them, they should be pre rendered on the server side

with Django or with SSR front end frameworks like Next.js

and we are having like Dynamic hundreds amount of tutorials

which are made by users all the time

If those tutorials would be made only by our developers, as often as we produce commits to front end

we could manage with pre-rendering them, instead of going full SSR

it would allow us remaining in CSR way, while having server side builds only during project building into bunch of those static files

[supple vault]

anyway to make a websocket server in python without using the async lib / an alternative lib

[inland oak]

so... if tutorials are written by users = we should use Django or Next.js
if tutorials are written only as often as commits to front go with our developers, we can use React(with React-snap?), or Gatsbi

just recently researched this topic

Next.js is universal frontend framework though

[ocean notch]

That sort of makes sense :x though i don’t fully comprehend the part about doing CSR when commits to front by developers

[inland oak]

Next.js can be used as SSR, as CSR with prerender or as purely CSR
in any way mixing all those three paths

universal thing to use

[quick cargo]

Next is nice

but its definitely orientated for vercel to host

not saying vercel does a bad job as a host

[inland oak]

yeah I noticed that too

[quick cargo]

but it made geo deploying with other cloud systems more awkward than say a regular react app

its not a big issue, but it can cause issues

[inland oak]

for example we are using react, with pre render with react-snap
we keep updated three tutorials about A,B,C stuff.

due to pre-render, when we would write 'npm run build` command
those tutorials would be compiled into bunch of html/css/js files

which will not be changed until we next time re deploy our web site
that makes updating those tutorials for search-engines not more often than we make commit in essence

[ocean notch]

Ah I understand you explain really well

Kinda killed my existing questions about CSR vs SSR with regards to SEO

[quick cargo]

generally the fact it complies to 'static' assets makes life much easier with deployment in terms of latency

things like github, cloudflare etc... all offer geodeployed static content serving

which is a bigggggg plus for user experience

[inland oak]

yeah. that's why I would prefer always CSR over SSR

when I can

[quick cargo]

SSR has it's place, if you have a page which changes often but is easy to cache e.g. it's rendered once then served hundreds / thousands of times before rendering again, it makes more sense to SSR it and stick it on a edge worker or just let cloudflare cache 90%+ of the requests

[worn shale]

Not sure if this is relevant to the conversation but are the .xyz domains free?

[quick cargo]

no

[worn shale]

Ahh ok

[ocean notch]

Yo dark if I know JS and react pretty well would it be hard to transition to django? I’m asking this knowing everyone learns at different pace but in general wondering about what you think transitioning to backend would be like if I already know a language and can pick up python decently fast

I know backend is trickier and there’s a ton to it

I have a year and a half in job exp only

In front end lol

Like I’m sure basic CRUD stuff and basic relationships can be learned easily and there’s even an ORM for queries

But there’s much more to backend

So ya..idk

[inland oak]

uh. hard to say.
I mean... I am sort of in your foots on the backside of the coin at the moment.

I can say that experience in backend would be much smoother, if you are friendly with Linux

[ocean notch]

Ahah you can pick up front end easy as long as you dive into JavaScript deep

[inland oak]

like a lot of back end things require easy navigation in Linux%

[ocean notch]

I use zsh same cli as Linux not sure if that’s what you mean

[inland oak]

in my opinion back end person should be able doing small stuff like
installing database for himself, setting webserver like nginx, able to attach ssl certificates, or getting domain for web site on his own
later goes stuff with caching through redis/memcached, celery which goes into redis database too, ci/cd with github/gitlab/jenkins piplines
docker with its many variations, docker-compose and e.t.c

all this stuff is easier when you are in linux

[ocean notch]

I’ve done a bit of node so I know how to do simple stuff other than like redis haven’t look into that yet

But some of those sound like dev ops stuff

[inland oak]

oh you worked with Node?

[ocean notch]

I’ve worked with micro services

[inland oak]

that would make transition to Django much easier

[ocean notch]

But not too In depth

[inland oak]

Node is basically backend like Django

[ocean notch]

Yeah but just the basics

[inland oak]

anyway
i like this map
https://github.com/kamranahmedse/developer-roadmap
it makes nice goals to learn in any path

[ocean notch]

I can build api end points am familiar with some lingo

Ahh ok

I have it book marked hah

[inland oak]

yeah, it is.
but backend skill is really highly improved with a touch of devops skill, those two skills are highly adding to each other

like frontend person could be improvied with design ui/ux

[ocean notch]

Ohh

I see

Yeah I’m not too into uiux stuff that’s why I wanna get into backend now that I’m in between jobs

That makes sense

Can I add you? Maybe we can exchange two different sides of the coin sometimes

[inland oak]

sure 😉

[ocean notch]

I’m no expert but I know js and react

Thanks

[ocean notch]

So I take it your company does embedded react

[inland oak]

embedded as in?

we are using standalone react with django rest framework, both are completely separated

react, we are using Create React App verison

[ocean notch]

Oh sweet I was starting to feel like seldom any company does standalone

With django

[inland oak]

perhaps if I'll be knowing both things together

I'll consider going with embedded too ;b

may be

[ocean notch]

Ahaha I know there’s some benefit to embedded

But I prefer standalone

Easier to separate the logic

Like being able to use react router instead of relying on backend

For the URL’s

[inland oak]

well, I would go as first step for learning standalone front anyway

because it would make better dive into frontend

once I'll learn standalone, I'll consider using other ways

[ocean notch]

Nice that’s probably good to know both

[inland oak]

I am going to start on learning frontend on the next weekends probably

on thursday going to arrive book which I plan to use getting started

Head First O'Reilly Html + CSS

• Head First O'Reilly Javascript

[ocean notch]

Haha nice dude like I said I’m in between jobs so hit me up anytime

For JS

Or React

[inland oak]

heh, it would be probably not the super fast learning

like I am having a big queue to learn of backend + devops things%

[ocean notch]

I’m reading effective python and doing some tutorials on django

[inland oak]

plus working at the same time

[ocean notch]

Ahh

That sounds like a load

I’m doing full on backend right now

[slow gazelle]

is flask being used in production?

[inland oak]

nope, Django.

[slow gazelle]

or should i go straight in django

oh ok

[inland oak]

flask is nice to learn and getting started though ;b

[slow gazelle]

yeah i got bored thou xD

[inland oak]

Django is full battery included framework

a lot of things pre setup for you

a little bit... easy to get used to it%

[slow gazelle]

when do you think is good for using flask? in my observation i think its good to used for simple services like firebase

[ocean notch]

Ya also a lot more magic to understand and gotta dive in the source or docs a lot haha

[slow gazelle]

or still django

[inland oak]

well, there appeared major new Flask verison, perhaps it will start going on the same pair as other async frameworks... one day

shrugs
I am not sure what for flask is useful. I did not get it tbh.

before its major upgrade it was not useful in my opinion

because any framework had some feature that made it better than flask in every way

with last major flask upgrade, perhaps it will stop being this way

[slow gazelle]

yes , i'm only concern is the job market

so django it is

[inland oak]

then go for django 😉

I heard Fast API is useful too though

noticed often enough in job positions
quite popular to be used in commercial too

[warm igloo]

I use Flask a lot. I really like FastAPI as well. Django often is just way more magic than I want to deal with.

[manic frost]

Yes, for example, the authors of the Cosmic Python book (https://www.cosmicpython.com/book/preface.html) say that they're using Flask at https://made.com.

but it seems that Django is more popular.

you can check the robots.txt file, or read the TOS of that website

website.com/robots.txt

if you see "are blocked/disallowed" next to "User-agents" then it's illegal

how to run a function once my api server is started in flask?

[ionic raft]

Anyone here have experience using PyCharm and bootstrap grid?

Because while I can get grid to work in Codeply....even with copy/pasted html I simply CANNOT get columns to stack properly...

<div class="row">
    <div class="col-lg-6">Col</div>
    <div class="col-lg-6">Col</div>
</div>```

prints
col
col

no matter how wide the browser...and it's breaking my brain. Like I said, this works in Codeply...but Pycharm? Not a sign of it working. I also have```html
head>
<meta charset="UTF-8">
<title>Title</title>
<link rel="stylesheet" href="../static/css/bootstrap-grid.css" type="text/css">
<link rel="stylesheet" href="../static/css/bootstrap.css" type="text/css">

</head>```

So I know I'm calling the stylesheets. I've been following a video tutorial and even copy/pasting this isn't working! I'm getting to the point of ditching PyCharm to be quite frank

I really need Grid to work, and Pycharm refusing to render is driving me nuts

[cerulean vapor]

what do yuo mean by getting this to work in PyCharm? are you using some kind of HTML previewer?

[ionic raft]

Well, Flask...but while I'm building out the page and learning Grid in Bootstrap Pycharm has a browser function

[cerulean vapor]

also what version of bootstrap

[ionic raft]

4.6.

[cerulean vapor]

I would just open the flask app in whatever browser your nomally use

I have no idea how PyCharm does web rendering

[ionic raft]

I've got the right version of css file. And I know I do because I copy/pasted css from codeply...where GRID works!

Doesn't work in Flask either!

But codeply...perfect. Copy pasted html and css files...works on Codeply. Pycharm, no dice! GRRR

[cerulean vapor]

open your inspector and make sure the css files are loading

[ionic raft]

Good idea...

[cerulean vapor]

you might want to use nonrelative URLs for them

e.g., href="/static/css/...."

[ionic raft]

Yes....loading

Showing css in "Styles"

Hm....bootstrip-grid.css isn't showing tho

OMG!

So, yeah....you have to make sure that bootstrap-grid is in the header

Thank you @cerulean vapor
I'd already checked for the loading css file, but missed that they separated out grid as it's own css file!

[cerulean vapor]

Hello ppl, I'm pushing django website on Heroku, only one of my webpages - 'dashboard' throws Server Error 500. I checked the templates correctly according to WhiteNoise configs, set debug=False, migrated the db. Can anyone help me with this?

I suspect line 13 is probably the cause of 500 error

[surreal portal]

This tutorial is from 2016. I hope nothing much has changed

Although it must use Django v2

[ivory bolt]

I think your url should look something like this:
/int:id/ right?

[obtuse trout]

it is yeah in urls.py

[obtuse trout]

can you please help?

is there something I'm possibly missing out..?

[ivory bolt]

I'm not entirely sure, though I guess it is
return redirect('dashboard/<int:{}>/'.format(request.user.id))

check this out

I'll get back to you with a better answer

[grand harbor]

if it was flask i would use it like this @app.route("/post/<string:slug>"

[obtuse trout]

I'll just check it out, thanks a lot mate

[obtuse trout]

never used flask before 😅

url is like this now, it doesn't take <int:> / reads it as a string

[ivory bolt]

can I see your views.py

check out the url parameters for django in their documentation

[obtuse trout]

why not.
but Django admin panel would save a lot of time btw

Does anyone know how to get this working with A SAMACCOUNTNAME?

https://soshace.com/integrate-ldap-authentication-with-flask/

[ivory bolt]

why don't you replace pk with just *args, **kwargs

and is there a way to change the url to uuid or something

I'll check it out and let you know in a bit

[obtuse trout]

like we use in password-reset-confirm?

path('reset/<uidb64>/<token>/'

[native tide]

is this flask or django?

[obtuse trout]

django

[native tide]

thats why

i felt stupid

[obtuse trout]

doesn't work - I use pk user_id=pk

@ivory bolt can we use HttpResponseRedirect instead of redirect ?

[surreal portal]

Has anybody else manipulated django-filter with DRF? Because I'm kinda lost at a filter's creation

All i want is to have options to filter on the date

[primal thorn]

i followed the docs for the phonenumbers field and imported it like this ```python
from phonenumber_field.modelfields import PhoneNumberField

but it still says ```ModuleNotFoundError: No module named 'phonenumbers'```

i installed it like this pip install django-phonenumber-field

[obtuse trout]

just write - pip install phonenumbers

[scarlet kiln]

does anyone know how flask's url_for() works? My understanding is that it supplies the route in the function decorator after searching for a function with the name you supply to url_for() but flask/jinja keeps insisting it can't find it

[surreal portal]

You have to import it from flask first

[scarlet kiln]

I did

and I believe I don't actually have to

since it's supplied automatically by flask when reading templates

or something like that

[surreal portal]

Yeah you can use it in Jinja2 templates without importing it

[obtuse trout]

Anyone - what would you write @ here in url(r'^dashboard/<here>') so that it accepts all positive numbers?

[scarlet kiln]

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>test</title>
    <link href="{{url_for(send_stylesheet)}}" rel="stylesheet"/>
</head>
<body>



waow
</body>
</html>```

gives me jinja2.exceptions.UndefinedError: 'send_stylesheet' is undefined

wait

from flask import Flask, abort, redirect, render_template, request, send_file, jsonify, url_for

app = Flask(__name__)


@app.route("/")
def index():
    return render_template("test.html")


@app.route("/static/styles.css")
def send_stylesheet():
    return send_file("static/styles.css")


if __name__ == '__main__':
    app.run(debug=True)

this is the correct py file

how can jinja not find the send_stylesheet?

[opaque rivet]

url_for('send_stylesheet') the argument should be a string

[scarlet kiln]

oh so even within django I need to denote it as a string

doesn't help

wait

mb it didn't reload because

I didn't add the auto reload parameters

[opaque rivet]

same error?

[scarlet kiln]

nono it worked

now I need to figure out

why it didn't work in the main project even after making that adjustment

never mind you just solved my problem

I was chasing my tail on this for so long

because I transferred this from a google colab to my local environment

and was sure I'd gotten some esoteric configuration wrong

that I didn't consider the obvious

thank you <3

can I ask a follow up question?

[opaque rivet]

sure

[opaque rivet]

(?:dashboard)/(\d+) should work

I highly recommend https://regexr.com/ for making regex patterns

[scarlet kiln]

I am not trying to regex

[obtuse trout]

is it correct? @opaque rivet

[scarlet kiln]

I am having trouble getting something from request.form

[opaque rivet]

I think it's right - write some unit tests to make sure!

[scarlet kiln]

oh you weren't answering me

mb

[opaque rivet]

what's the issue?

[scarlet kiln]

function onDomLoaded() {
                    document.getElementById("filterbutton").addEventListener("click", function() {
                      var weekdays = [];
                      $("#dayfilter input:checked").each(function() {weekdays.push($(this).val())});
                      $.post("{{url_for('filter_map')}}" , JSON.stringify({"weekdays": weekdays}), onAjaxResponse, "html" );
                    });
                  }```

I use this code to post the values of checked checkboxes in an array

and used jquery post to send it

but it somehow seems to be the incorrect format for flask

it sends the request with the form data

but when I try to use request.form["weekdays"] I get a KeyError

is stringifying it wrong?

it sends a different error if I don't stringify it

but it has an error in either case

[opaque rivet]

hmm, seems that request.form is empty because flask doesn't recognize that you submitted a form.
I'm pretty sure you could access request.data and your data will be there. Looks more like an API call than a form submit to me

[scarlet kiln]

so am I doing something stylistically wrong?

[opaque rivet]

not sure. Have you checked if request.form is actually empty? It could be that Flask is detecting a form, but the payload is a string because you did JSON.stringify({"weekdays": weekdays}) so there are no keys to be accessed

[obtuse sedge]

Oh my gosh today all the channels are full

[primal thorn]

its still giving me the same error

[scarlet kiln]

@opaque rivet the thing is there is something in request.form

and I figured it would be empty if it wasn't recognized

lemme trying it now

[obtuse trout]

are you using venv?

[primal thorn]

yes

[opaque rivet]

check the type of its contents, it might be a string since you're doing JSON.stringify({"weekdays": weekdays}) @scarlet kiln

[obtuse trout]

make sure its activated when you install

[primal thorn]

it is activated

[opaque rivet]

do pip list in the terminal, does phonenumbers show up in the list?

[primal thorn]

yes it shows up as phonenumbers 8.12.25

maybe im importing it wrong in my models.py?

[obtuse trout]

probably

[primal thorn]

i tried using the command pip install django-phonenumber-field[phonenumberslite] but it says the package does not exist

[scarlet kiln]

this is what's in request.form

I am not sure how to work with it

and I feel like I'm doing something wrong in terms of style

I removed stringify

let's see what happens if I put it back

[primal thorn]

i fixed it, i had to install phonenumer and django-phonenumbers

[scarlet kiln]

this is with stringify

[opaque rivet]

yeah, my guess was right. Your request.form payload is a string

your error lies here JSON.stringify({"weekdays": weekdays})

[scarlet kiln]

so you're saying I should remove stringify?

either way it doesn't seem to enter request.form correctly

or do I need to modify the js object I'm sending as the payload?

[opaque rivet]

that's up to you. You can do: json.loads(request.form)['weekdays'] to convert the str into a dict

[scarlet kiln]

so I was sending valid json

but flask doesn't know what to do with it

because as far as it knows it's just a string

the issue is

request.form is a ImmutableMultiDict

not a string

and I'm not sure how to access what's inside the object

and I get keyerror if I try to do request.form['weekdays']

so I think I have to supply something different in the jquery post

can I index into a dict?

keyerror

[opaque rivet]

yeah, supply something else in the jquery post. request.form is a ImmutableMultiDict but its contents is a string...

maybe you could do something like:

mutable_arr = [data for data in request.form]
json_string = mutable_arr[0]
data = json.loads(json_string)

if request.form is an iterable

I don't work with flask so I don't know too well

[obtuse trout]

great

[primal thorn]

how do i remove the first name, lastname, and email fields from the user model

but i want to keep all the other fields like email, password and permissions

[surreal portal]

https://testdriven.io/blog/django-custom-user-model/

does anyone know about any android app development course

[subtle frost]

this is a web dev group on a python discord 😂

[autumn yoke]

yeah ikk
i just thought if by anychance anyone knew

[glacial sky]

aoba

someone?

[subtle frost]

don't think you can do that 😄

what's the error?

[glacial sky]

idk

[subtle frost]

mouse over it

[glacial sky]

look

[subtle frost]

yea you can't do it

maybe try python self.botao1.place = (2.0, 2.0)

[glacial sky]

nice

work, but wheres my button??

[subtle frost]

maybe check the docs for Button. Dunno how tkinter works.

[ripe lodge]

did anyone do corey schafers django series, and if yes did you like it?

[glacial sky]

ok, ill see

[subtle frost]

@ripe lodge you tried the Django docs and getting started tutorial? There's enough info on there to be a pro 💪

[glacial sky]

whats the difference of tkinter of django?

[ionic condor]

self.botao1.place(relx=2, rely=2.0)```

[subtle frost]

tkinter is a gui (like desktop apps)

django for making websites with a backend

[subtle frost]

haha that makes way more sense. was confused about that 😂

[ripe lodge]

im gonna look into it more, i feel like it's kind of overwhelming for a noob like me, i just dont understand a lot of the vocab yet xd

[glacial sky]

like html?

[subtle frost]

Yea that makes sense. I got a job using Django before I'd ever used it. I just keep re-reading the docs all the time. The Django discord really helpfull!

[subtle frost]

yea for the frontend

django/python for the backend

[glacial sky]

i just wanted my button ):

[subtle frost]

You tried this: #web-development message ?

[ripe lodge]

that's awesome man! yea once you understand the basics i imagine the docs are really useful. thanks for the tip!

[glacial sky]

yes

[calm plume]

No, it works alongside html. You use html, css, and maybe js for the frontend, and you could use django for the backend

[subtle frost]

loads of the videos are crap. Feels like they never used Django, reading the docs and making a video based on that tutorial 😂

[glacial sky]

its working but my button it disappeared

[glacial sky]

whats is "backend" ?

[subtle frost]

it was visible but then went away?

[glacial sky]

no

[calm plume]

The part of the website that interacts with the database, does calculations, things like that

I'm not really sure how to explain it

[ripe lodge]

yea ive been through a lot already, you're so right! also did the python crash course webapp project but i feel like after just following along all the steps i still dont really get the basics, i made an app but i dont actually understand what im doing.. it's always a process i guess

but i hear the corey schafer series is supposed to be good

[subtle frost]

@glacial sky https://www.tutorialspoint.com/python/tk_place.htm

[glacial sky]

u.u

[ionic condor]

are you sure you want relx & rely and not just x & y

[calm plume]

That one is really good

He's a wonderful teacher

[ripe lodge]

ah that's good to hear, i'll start rn. ty!

[glacial sky]

I need relx because the application will scale for the user

[ionic condor]

relx & rely are floats between 0.0 and 1.0, but you might be better to use pack or grid then placing widgets.

[glacial sky]

work, tks

[ivory bolt]

honestly redirect is just so much cleaner

wouldn't recommend that

[glacial sky]

i was using (1.5 and 3.0)

[viral ember]

Hi
i don't know if this is the right chanel, but anyways:
I have 2 apache webserver and want to redirect from the first to the second server everytime someone gets on the website. Also show some basic text so that a user can see that is was redirected to another site.

(it's nothing serious, just for fun 😄 )

f.e like this one: https://heeeeeeeey.com

but within a network and ip's (like i said, just for fun)

[inland oak]

As super easy solution... just host in apache regular web site, which according to apache tutorials, always in www folder. Serve its any index.html

Then add simple html syntax to this index.html for delayed redirect, I think there should be one

https://stackoverflow.com/questions/3292038/redirect-website-after-specified-amount-of-time

[viral ember]

thx 🙂 i'll try it out

[upbeat umbra]

Thanks

[viral ember]

uhm one problem 😄

it works, but when it tries to reidrect, it just puts the text infront of the other which leads to a wrong adress... 😄

[upbeat umbra]

Is there a way around that?

[upbeat umbra]

I see for example flashes arou put to the wrong pages too.

[viral ember]

oh sorry, it works now 😄

btw do you know how i can add some text (sorry i'm a complete noob at this 😄 )

Sorry I was not keen, I am replying to the wrong message

@inland oak hello bro , i feel like i'm stuck not learning anything new or just learning same thing's im different framework's as u and many suggested me when i was Doing Flask if u wanted to go to advaned get to Django is it structured and stuff like that now i have done , 1 yt video 8:30 hrs and 8 docs and made 1 that docs project and 1 todo app from yt and what should i do , i wanted to learn how can i use react with django that api i want to learn i want to learn postgresmysql and to use it on django how can i use phpmyadmin on django stuck bruh feeling like i cant make progress

plz help

[dusk portal]

https://docs.djangoproject.com/en/3.2/intro/ this docs

[ivory bolt]

well, if you really feel like you're not making any progress, I suggest you try to build a social media app

You can try building a simplified twitter clone

[dusk portal]

how can i dont have that much knowledge

[ivory bolt]

I mean, yeah you don't, but you also kind of do

You already know how to handle authentication, create models and fields

linked tables

and managing requests and urls right?

Do you know how to create an API?

See -- here it is! Try to look at the things you know and those you DON'T. In your case, I assume it's:

1. Creating an API
2. Writing asyncrhonous code -- using websockets or updating data real time
3. Creating a frontend

I can hook you up with all the resources needed to do just that -- I also have a tutorial SPECIFICALLY for just that (react and Django twitter clone app)

I'll send it to you separately if you want @dusk portal

I suggest you try to do something you've always wanted to and RESEARCH how to do it -- it's how I learnt and I honestly think it's the best approach

[dusk portal]

yes plz @ivory bolt

idk api and stuff

yes ik databases urls and stuff

[ivory bolt]

see, there you go!

I'll send you whatever you need to get started tomorrow morning, so stay tuned on the server!!

[misty goblet]

Using the Django rest frameworks's serialisers is there a way to call a nested objects update and create methods?

that would let me do something like this:

class GuildSerialiser(ModelSerializer):
    snowflake = IntegerField()
    channels = ChannelSerialiser(many=True)
    roles = RoleSerialiser(many=True)

    class Meta:
        model = DiscordGuild
        fields = ['snowflake', 'channels', 'roles']
        list_serializer_class = CreateUpdateDeleteListSerialiser

    def update(self, instance, validated_data):

        self.channels.update(instance.channels, validated_data["channels"])
        self.roles.update(instance.roles, validated_data["roles"])```

it seems that the serialiser fields get removed when they are created

and there you can access them through self.fields.channels that doesn't work properly

[inland oak]

um yeah

it is possible

but I cheated

[misty goblet]

I have 'cheated' as well now

[misty goblet]

I have this horrid function ```python
def create_update_deleteList_serialiser_update_substituation(model, instance, validated_data):
# Maps for 'snowflake->guild instance' and 'snowflake->guild data' item.
instance_mapping = {item.snowflake: item for item in instance.all()}
data_mapping = {item['snowflake']: item for item in validated_data}

# Perform creations and updates.
output = []
for snowflake, data in data_mapping.items():
    item = instance_mapping.get(snowflake, None)
    if item is None:
        output.append(model.objects.create(**data))
    else:
        output.append(item)

# Perform deletions.
for snowflake, item in instance_mapping.items():
    if snowflake not in data_mapping:
        item.delete()
return output```

[inland oak]

https://www.django-rest-framework.org/api-guide/relations/#writable-nested-serializers
here how to not cheat

Writables Nested Serializers section

[misty goblet]

that isn't using the nested serialiser though

it is creating the nested object in the parent

[inland oak]

link surely uses nested serializer

[misty goblet]

    def create(self, validated_data):
        tracks_data = validated_data.pop('tracks')
        album = Album.objects.create(**validated_data)
        for track_data in tracks_data:
            Track.objects.create(album=album, **track_data)
        return album```

where is the link?

it doesn't call the nested create

it is only using the nested serialiser for validation

because this is horrid: ```python
def create_update_delete_listserialiser_update_substituation(model, instance, validated_data):
# Maps for 'snowflake->guild instance' and 'snowflake->guild data' item.
instance_mapping = {item.snowflake: item for item in instance.all()}
data_mapping = {item['snowflake']: item for item in validated_data}

# Perform creations and updates.
output = []
for snowflake, data in data_mapping.items():
    item = instance_mapping.get(snowflake, None)
    if item is None:
        output.append(model.objects.create(**data))
    else:
        for i, value in data.items():
            if i == "snowflake":
                continue
            setattr(item, i, value)
        item.save()
        output.append(item)

# Perform deletions.
for snowflake, item in instance_mapping.items():
    if snowflake not in data_mapping:
        item.delete()
return output```

especially when this functionality is already implemented in the nested serialiser

now it is saving correctly

but I cannot access the serialiser's .data

AttributeError: Got AttributeError when attempting to get a value for field `snowflake` on serializer `GuildSerialiser`.
The serializer field might be named incorrectly and not match any attribute or key on the `NoneType` instance.
Original exception text was: 'NoneType' object has no attribute 'snowflake'.```

I failed to return the instance in a .update() function

done!! working now

[ivory bolt]

oh k

did you change your url? Curious to see how you solved it

[dusk portal]

simple , when u see views.py i wrote return render in iteration so it was not catching it is the end then later i removed that from iteration and it got fixed

[ivory bolt]

I don't see an iteration…do you mean the if statement?

ohh yea

wow k yea you didn't specify anything for a GET request so

[nimble radish]

is there any way to interact with a django database model outside the app

ex. i'd like to add some entries to the database from a separate python script

[dusk portal]

my first question is why u wanted to do that @nimble radish

cez it doesn't make any sense ;-;

[nimble radish]

Well, I'm figuring out the structure of my project right now.

I know I'll be using Django for the web app, but I'll have another part of the project (a separate Python script) that takes data from elsewhere and I need to add that to the database to be used by Django. I'm just trying to see what my options are.

I'm trying to figure out if for the separate part if I need to use actual SQL queries, and if I do, then maybe I shouldn't use the Django models at all. I'm not too sure, it's my first time using Django.

[dusk portal]

I shouldn't use the Django models at all. why

[nimble radish]

Are you reading my posts? I said I don't know what I'm doing, I'm using Django for the first time, and I'm just trying to get ideas on whats possible.

[native tide]

By an API, like GraphQL is a nice and simple,
or just import the models and use the django functionality

[dusk portal]

any django exp. dev?

show code and error

i was pretty good in flask

post.description= updateoriginfo.description.data #after this line where db.session.add line where is var u passing all the items

are u sure u r doing right?

[glacial sky]

tks @subtle frost I managed to finish my mini project for today , if you can give a star please

https://github.com/Gusztavo/calculadora_simples

[native tide]

its like the db didnt receive an email value because the null value not allowed by default

[dusk portal]

so what should i do

[native tide]

if u dont want the email to be required
u need to provide default value for email field, like default=''
or allow the the db to store it as null, by doing null=True

also to tell the html its allowed to be blank, put blank=True

[dusk portal]

ohk

[obtuse trout]

yes you can, identify your database -> create connection -> using pandas, you can read data and add to your database

[supple vault]

is there a library for websockets that isnt async

server not client ^

[ivory bolt]

you can't leave email empty OR you are using an email field right now

You should be able to get more traceback info there

[spare dragon]

weird question just having trouble finding an answer

anyone know Kotlin in here?

[naive rock]

So I have an async routine, that sometimes works and other times fails.
Couple of time when it failed it returned 500 status code, which means the server is temporarily down?

This async routine worked fine when it made around 600 async api requests. But now it's making around 800 async api requests. Could the increase in async calls be a problem?

[gritty cloud]

probably

you may have unintentionally overloaded the server

or the service the api runs on may be overloaded bc of ur requests

also a 500 means the server went and did something weird

[naive rock]

I can try to catch the error, put the program to sleep for 3 seconds and then retry again. Thanks!

It's moments like these I just think to myself programming is more about hacks then programming.

I felt more so this way about Frontend. Python and backend for the most part is well thought out logic with fewer "hacks".

[vestal hound]

can you elaborate on that

[vestal hound]

500 is a general "something went wrong on the server" code

some servers will return 503 in case of overload

[vestal hound]

why not make that script a Django management command?

then you can interact with the database using the ORM

ultimately it's just SQL tables so you can write raw SQL if you want, but I don't see why you'd want to

[nimble radish]

first time working with django, i've read through some documentation but im mostly learning through cs50's django lectures. i'm not sure of the full capabilities of django

[vestal hound]

okay so

[nimble radish]

i'll look into that though, thank you.

[vestal hound]

you know how you can run, for example

./manage.py makemigrations?

that's a management command

defined in Python code

that just does stuff with the Django framework loaded

you can do the same thing in your own code

so you have access to all of Django's capabilities

including the ORM, so you can work with model instances and save them etc. and it'll take care of writing to the database for you

[nimble radish]

https://docs.djangoproject.com/en/3.2/howto/custom-management-commands/ is this what you're talking about?

[naive rock]

Response that I get is an XML in bytes so to capture the error, I did this fast, but dumb thing:

Hey I have a question, if I know that I can create a whole website using Django, I have no experience in this library, but what I know about it that we can create websites on it, my question is, so when we inspect the web page of it we will get a python code ? Or how ?

[wooden ruin]

function addStar() {
    const geometry = new THREE.SphereGeometry(0.25, 24, 24)
    const material = new THREE.MeshStandardMaterial({ color: 0xffffff})
    const star = new THREE.Mesh(geometry, material)
    const [x, y, z] = Array(3).fill().map(() => rand(50)) // random float from -n/2 -> n/2
    star.position.set(x, y, z)
    scene.add(star)
}
Array(200).fill().forEach(addStar)

currently messing around with three.js, but there's some weird array stuff that I'm seeing when I follow a tutorial. what does Array(200).fill() do, and how does map work?

[primal thorn]

Python can be used for web dev ??

If yes How ?

And in what

Yes

Do the flask, django or fast-api tutorial depending on your needs.

You still need to use html, css and js for the front end . Or is that what you want to avoid

this is probably new enough

from django import forms

from .models import Player


class PlayerForm(forms.Form):
    name = forms.CharField(widget=forms.HiddenInput())

Actually scratch it

hidden fields probably will not work for this case

better or may be it will

if it will not work, store previous values in query params or cookies or smth

storing in cookie sounds actually the easiest way

cookie can be well managed with backend

i plan to manage it from views

and send messages for error is it good??

[edgy sable]

can someone help me and tell me how to get my flask app to work with my domain?

[inland oak]

depends on what you have as your domain

is it just domain and nothing else?

a regular solution... would be getting vps server

getting ssl certificates for your domain

and deploying on the vps server, your app with attached ssl certificates

while setting in your domain provider, things to point to your VPS ip address
