[native tide]

any solution for extends ?

or humanize?

[devout coral]

@native tide There is no real built-in way to do this unless you want to write your own template loader function. With that said however I do not see any benefit in doing something like this. Other django developers are used to this convention will be expecting it and will make things easier for the next person reading it since it is explicit.

@native tide Did you have a question?

I personally have not used it so I cannot have a very good opinion. Maybe someone else here can.

[late gale]

I asked a question here and all questions have been answered except mine can someone help me please

[devout coral]

@late gale Lets give it a try.

[late gale]

?

[devout coral]

You are using crispy forms correct?

[late gale]

yes

[devout coral]

using the |as_crispy_field filter right?

[late gale]

yes

[devout coral]

Cool, are you passing it the entire form?

Or a specific field?

[late gale]

entire form

each input has |as_crispy_field| so i can organize them

[devout coral]

Yeah that is the problem. If you want crispy forms to render your entire form for you then use the crispy tag. If you want to have your individual fields to organize them yourself then you need to use |as_crispy_field and pass it each field you want to display with the crispy forms css/js

[late gale]

yes i want that to display with each field

srry

so i can add css and javasript yes

[devout coral]

Cool, no need to be sorry. Do you understand how to sort of do it now?

Yes, you could add css and js to if you want.

[late gale]

yea i sorted just between an open div tag and close i add the field with the crispy field with it

[devout coral]

Yep, and ensuring you pass a field as opposed to the entire form will get rid of that pesky error you were getting.

[late gale]

still i dont know what i do wrong

did u look at the html ?

there

[lavish prism]

Hey @late gale!

[devout coral]

No, did you post the HTML?

[late gale]

there

yes i did

https://paste.pythondiscord.com/aculaqelen.xml

[devout coral]

Where is it?

[late gale]

there

[devout coral]

Thanks

You are receiving the same error?

[late gale]

yes

although it was working very perfectly and i didnt even touch it

[devout coral]

Could I see the error again?

[late gale]

sure

[devout coral]

Alright, so let the debugging begin.

Go ahead an comment out every single field but the first one please

[late gale]

you mean i comment every field and run the server and see if thats working ?

[gaunt marlin]

i think boundfield is in django.forms, not in django.forms.forms

[late gale]

i cant find find boundfield

there is no bound field in my models or forms.py in all apps lol

[gaunt marlin]

oh ok then forget what i said

[late gale]

programming is hilarious

[devout coral]

Have you tried commenting all the fields but one?

[late gale]

i am trying now

wait

[devout coral]

Ok

[late gale]

ok i commented the whole form

and the error didnt remove

so i believe the error doesnt come from the template

wait

yea no change

so the error is not in the template file

[devout coral]

Ok cool

[stable kite]

@late gale your error is in your form not in template

[native tide]

Yea but django.forms.forms doesnt have that

Rught

[devout coral]

So put it back to normal. and lets go look at your views really quick (granted the issue is probably in forms but better safe than sorry)

[native tide]

Shouldn't it be django.forms

[late gale]

@native tide ik i swear but i dont even have boundfield

look my forms.py

from django import forms
from django.contrib.auth.models import User 
from django.contrib.auth.forms import UserCreationForm
from .models import Profile

class UserRegisterForm(UserCreationForm):
    email = forms.EmailField()
    class Meta:
        model = User
        fields = ['username', 'email','password1', 'password2']


# USER UPDATE FORM!!
class UserUpdateForm(forms.ModelForm):
    email = forms.EmailField()
    class Meta:
        model = User
        fields = ['username', 'email']

#PROFILE UPDATE FORM
class ProfileUpdateForm(forms.ModelForm):
    Committees = (
        ('IT','IT'),
        ('Design','Design'),
        ('ER','ER'),
        ('Design','Design'),
        ('Marketing','Marketing'),
        ('Coaching','Coaching'),
        ('Media','Media'),
        ('Branding','Branding'),
    )
    committee = forms.ChoiceField(choices=Committees, required=False)    


    class Meta:
        model = Profile
        fields = ['bio', 'image', 'position' ,'committee', 'achievement','awards', 'experience']

ok gonna show u my views

@login_required
def update_profile(request):
    for userp in User.objects.all():
        try:
            u = userp.profile
        except ObjectDoesNotExist:
            u = Profile.objects.create(user=userp)


    if request.method == 'POST':
        user_form = UserUpdateForm(request.POST, instance=request.user)
        profile_form = ProfileUpdateForm(
            request.POST, 
            request.FILES,
            instance=request.user.profile,
            )
        if user_form.is_valid() and profile_form.is_valid():
            user_form.save()
            profile_form.save()
            return redirect('/profile')

        
    else:
        user_form = UserUpdateForm(instance=request.user)
        profile_form = ProfileUpdateForm(instance=request.user.profile)

    context = {
        'user_form': user_form,
        'profile_form': profile_form,
        'title' : 'Editting Profile'
        }

    return render(request, 'users/update_profile.html', context)

Views

there

thats the part where django refers to the url

and thats all the import things

from django.shortcuts import render , redirect
from django.contrib import messages
from .forms import UserRegisterForm , UserUpdateForm, ProfileUpdateForm
from django.contrib.auth.decorators import login_required
from django.core.exceptions import ObjectDoesNotExist

from django.contrib.auth import login, authenticate

[native tide]

@late gale you're using crispy forms?

[late gale]

yes

i hope we can fix this error

idk why this error refers to a thing that doesnt exist in my code

its like my computer wants to make an error without even know why

lol

[stable kite]

@late gale the error is not in your code it is in crispy forms i think so

[late gale]

maybe it needs an update

let me see

[devout coral]

Well you would not get the error unless you used the filter tag. So I am not sure why you are still receiving the error. Try commenting out the include for the crispy filter.

[late gale]

ok

[gaunt marlin]

you case seems to be the same as this one https://stackoverflow.com/questions/64499993/why-is-django-crispy-forms-throwing-module-django-forms-forms-has-no-attribut

they fixed it by updating crispy form

[late gale]

as i said

let me try now

[gaunt marlin]

are you using conda to manage your package ?

[late gale]

nope

i am using pip

[gaunt marlin]

oh ok

[late gale]

pip install django-crispy-forms should i update it by this?

[gaunt marlin]

pip show django-crispy-forms to show which version you have first

[devout coral]

do a quick pip show django and pip show django-crispy-forms

[late gale]

k

django version 3.1.3

the latest cool

the cirspy forms

version is

1.8.1

[gaunt marlin]

from crispy form django
django-crispy-forms supports Django 2.2, 3.0 and 3.1 with Python 3.5+. Note: Django 3.1 requires `django-crispy-forms` version 1.9 or higher.

[devout coral]

Yeah update to 1.9.2

[gaunt marlin]

yeah you need to update

[late gale]

using this pip install django-crispy-forms

?

right?

[devout coral]

That should install the latest but just to be sure do pip install django-crispy-forms==1.9.2

[late gale]

ok

[gaunt marlin]

``` will update your package to latest version too btw

[late gale]

cool let me try now

omg

it worked

xDDDDDD

Thank you all of you

so it was that thing

stupid packages

[devout coral]

How long have you been working on this project

Did you upgrade Django recently or something? Just seems odd this happens out of the blue.

[late gale]

like 5 months i believe and even more

yea i just upgraded recently

didnt believe that packages need to be updated too

lol

silly me

[gaunt marlin]

for development i recommend not using the latest version of your django, as latest version would sometime required other packages to update their package to support latest django version too

[late gale]

how to know if a package need to be updated

without getting into errors

and yea thank you as well

[gaunt marlin]

you could use a package manager

[late gale]

you too @devout coral

[gaunt marlin]

like pipfile

in pipenv

because everytime you update pipfile other package get updated too

[late gale]

can conda update them as wel

[gaunt marlin]

i don't used conda, i used it once and stop using it XD

i just use pipenv or poetry for packages managers XD

[late gale]

but most ppl seems to say

DOWNLOAD ANACONDAA

its perfect for python

and it seems its not

[gaunt marlin]

nothing is perfect, based on people opinions

[late gale]

how to use pipenv or poetry then

i download them and ?

thats it

?

[gaunt marlin]

those should have documents on how to use

https://pipenv-fork.readthedocs.io/en/latest/

https://python-poetry.org/docs/

[late gale]

oh thank you

what do u recommend and easier to use

poetry or pipenv

[gaunt marlin]

poetry is newer, but i'm not familiar with. Pipenv is easier to use for me

just install pip env and go into a folder type pipenv shell in terminal

it will auto create virtual env for you

[late gale]

great let me try it now

[gaunt marlin]

but still better to follow pipenv document

[late gale]

i will

i installed it now

let me try to use it

[devout coral]

Which version of django changes the admin page to have this side bar like this?

[late gale]

the latest

3.1.3

mine

it looks cool

[devout coral]

That is so weird. I just updated too, not used to it.

[late gale]

yea same

u can customize ur admin page

[gaunt marlin]

3.1 @devout coral

[devout coral]

Granted I am going to replace my admin page soonish so I will just leave it.

[late gale]

i had 3.1.2 and didnt see that change

[devout coral]

Well I have 3.1.1

[late gale]

so it is 3.1 +

then

and wait

u can change ur admin page ?

[devout coral]

Yes

[gaunt marlin]

https://docs.djangoproject.com/en/3.1/releases/3.1/#django-contrib-admin

@devout coral

[devout coral]

You can overwrite the admin templates.

[late gale]

how so

i just saw a youtube link of that

but believed that was fake

[gaunt marlin]

you can override it

django document has a section about overriding admin templates

[late gale]

let me see

[devout coral]

Yeah, so just go into the venv to find all the template names and pick which one's you want to override. From there in the django projects template directory you can make a folder called admin and put whatever templates you decide to override.

[gaunt marlin]

you can even do sick stuffs with override like creating a package like this https://github.com/otto-torino/django-baton

[late gale]

if my admin page is like this

i will die proud

xDD

[devout coral]

Yeah there is a few packages out there to do that. However, you probably want to just have it styled to what your page normally looks like so users do not feel a disconnection when going to the admin page.

[late gale]

baton package has a tour

lol

and also seeing google analytics is super helpful

in admin page

[gaunt marlin]

it's all javascript

[late gale]

instead of having it on another link

yea @gaunt marlin

[devout coral]

Also, to not violate the django license I believe you need to at minimun remove/replace the text that says Django administration.

[gaunt marlin]

@devout coral really? where does it mention D: ?

[late gale]

I renamed it

to my website name

are all these charts working or just javascript

like if a user viewed my website will these charts changes

or just a look

[stable kite]

@devout coral do you use any cryptography for storing data in databse with django?

[devout coral]

@gaunt marlin It does not explicitly mention it anywhere but by reading their license I get that.

@stable kite Nope

[stable kite]

@devout coral ok because i created one

[devout coral]

@stable kite Created a what?

[gaunt marlin]

you mean this ? https://pypi.org/project/django-cryptography/

[stable kite]

@devout coral a django app that uses cryptography to store & retrive data

you mean this ? https://pypi.org/project/django-cryptography/
@gaunt marlin i have my own

@gaunt marlin https://pypi.org/project/Django-CryptographicFields

[gaunt marlin]

oh i also made a hash data system before, but it's for a project so i didn't make it a package

[stable kite]

@gaunt marlin i did'nt use django-cryptography because it does'nt allow us to filter data

[gaunt marlin]

yeah crypting data have trouble with searching for it in database

because hash data are randomly hashed

[stable kite]

yes but in my one you can do that also

[gaunt marlin]

you use key pair crypting way ?

like 1 key to 1 data

[stable kite]

you use key pair crypting way ?
@gaunt marlin no

[gaunt marlin]

or just 1 key for all data ?

[stable kite]

or just 1 key for all data ?
@gaunt marlin yes

[gaunt marlin]

oh cool i would check it out

[stable kite]

@gaunt marlin https://github.com/Shahprogrammer/Django-CryptographicFields

[gaunt marlin]

my previous system don't have the search system because i can't filter on it

[stable kite]

my previous system don't have the search system because i can't filter on it
@gaunt marlin that's why i created my own

[gaunt marlin]

nice

i gave it a star

[stable kite]

@gaunt marlin thanks

@gaunt marlin do you think i should make JSON &CSV field also?

because i don't think many people use it

[gaunt marlin]

json field i think maybe, but it's only if people use postgresql

[stable kite]

ok

[devout coral]

@stable kite Very cool.

[stable kite]

@devout coral what?

[devout coral]

The package. I responded late because I stepped away from my computer. I am at work so yeah.

[stable kite]

ok

[gaunt marlin]

@stable kite suggestion maybe add a function to decrypt and encrypt data too

[stable kite]

@gaunt marlin which string?

[gaunt marlin]

mistype i mean data

[stable kite]

what data?

[gaunt marlin]

any type like string, integer

take arg of those

and can encrypt it

[stable kite]

ok but i think you mean not to store it in database

[gaunt marlin]

yeah

just return the encrypted string or decrypted string

[stable kite]

ok but you can do that easily

with lot's of packages

[gaunt marlin]

it's just a suggestion

[vernal furnace]

yo

I have some concerns

[stable kite]

it's just a suggestion
@gaunt marlin ok i will think on it

[vernal furnace]

So I'm making a website with Django, but later on I want to turn the same website to an app on Android

Is it possible to use the same code or..?

[stable kite]

@vernal furnace you can use react as frontend if you want to do so

[vernal furnace]

What is that

react.js?

[stable kite]

@vernal furnace because django is backend & do stuff related to server

yes react.js or react native

[vernal furnace]

lol I suck at java

wait so I have to redo everything from scratch

?

ohh

So I can turn my website to an application but that will cost me performance

[modest shale]

guys

i need help

I wanna learn python authentication

can u help me

[stable kite]

guys
@modest shale what type of authentication?

[modest shale]

umm

web application

signup

[modest shale]

which one ?

sorry i'm new for web development

[stable kite]

i don't know about flask as i use django sorry

[modest shale]

oh...

thank you :3

[stable kite]

@modest shale check this out
https://www.digitalocean.com/community/tutorials/how-to-add-authentication-to-your-app-with-flask-login

[modest shale]

Ou thank you again

dudddd

im looking this btw

but i get the

internal server error

hell...

[stable kite]

paste your error and code someone who know flask will help you

[modest shale]

i cant paste

[stable kite]

[modest shale]

internal server error not showing my error

just shows 'internal server error'

i must do debug

[devout coral]

@modest shale You deployed using apache2?

[modest shale]

what is that

[devout coral]

How did you deploy your application?

@stable kite i writed this code

I- I dont know the error

cuz im new at the web programming

and i wanna learn authentication

[nimble epoch]

@modest shale what framework youre using? or you want to choose?

[modest shale]

Flask framework

[nimble epoch]

still need help with auth?

@modest shale?

[modest shale]

still need help with auth?
@nimble epoch yes

im stucked

cant fixing error

[nimble epoch]

so you need some extensions like flask_sqlalchemy(for storing the data in the database) and flaask_login(to login the user)

whats the error?

[modest shale]

so you need some extensions like flask_sqlalchemy(for storing the data in the database) and flaask_login(to login the user)
@nimble epoch i did that

[nimble epoch]

ok i got it whats the error?

[modest shale]

my error at the signup page

im entering email, name, password

and clicking enter

[nimble epoch]

ok...

[modest shale]

getting Internal server error

:c

and i cant create any table at the database

maybe this is the problem

?

[nimble epoch]

you using sqlalchemy?

for database right?

[modest shale]

yes

yes !

sorry for late answer

[nimble epoch]

no problem, did you do something like db.create_all() command because maybe it couldnt find the database

[modest shale]

hm

you maybe right

cuz i have'nt any table

[proper owl]

include code please, it is guessing game

[nimble epoch]

ok to make sure do a query on the use table

[modest shale]

listen guys

hold on

[nimble epoch]

ok to make sure do a query on the use table
Sorry i meant User table

[modest shale]

from project import db, create_app

[nimble epoch]

just db

then db.create_all()

[modest shale]

db.create_all(app=create_app()) (pass the create_app result so Flask-SQLAlchemy gets the configuration.)

look at this

i writed this = db.create_all(app=create_app())

[nimble epoch]

no passing nesaccery

just create_all()

[modest shale]

oookay -,+

[nimble epoch]

👍

[proper owl]

I am trying to save session variables from being deleted on server reboot or session close. Can I use pickle to serialize it and save to database? Bad/good idea?

[nimble epoch]

@proper owl sorry havent used pickle

[proper owl]

@nimble epoch have you ever tried to save session like that?

i just have that pickle idea, not sure what else is possible

[nimble epoch]

somethin like session['username']????

[proper owl]

more complex

[nimble epoch]

what you mean cause i dont use session myself i do it using flask_login

[modest shale]

guys !

[nimble epoch]

yep?

[modest shale]

i get new error

haha...

sorry

:(

but i want to fix my problems

[nimble epoch]

its ok

just whats that?

[modest shale]

i wrote 'flask run' to cmd

and i get this

hold on

Error: Could not locate a Flask application. You did not provide the "FLASK_APP" environment variable, and a "wsgi.py" or "app.py" module was not found in the current directory.

[proper owl]

why cant you just paste code?

[nimble epoch]

@modest shale ok now in the cli type FLASK_APP=flaskappname.py

[modest shale]

i writed

(venv) C:\Users\Cireael\Desktop\code\blog>set FLASK_APP =project

(venv) C:\Users\Cireael\Desktop\code\blog>set FLASK_DEBUG = 1

[nimble epoch]

no probably not because the error occures when you havent

ok ok wait

[modest shale]

?

[nimble epoch]

instead of doing this...

[modest shale]

w-what ?

[nimble epoch]

in your file where you have the app veriable type if name == 'main': app.run()

[modest shale]

im curious

[spare marsh]

0-o

[mental prawn]

is there any free and easy use website to learn and code a website?

[modest shale]

but im using lot of file

...

[nimble epoch]

so find it where you have the flask app var @modest shale

[modest shale]

ohoh, okay

[nimble epoch]

is there any free and easy use website to learn and code a website?
@mental prawn like what html css javascript??

[mental prawn]

python

[modest shale]

is there any free and easy use website to learn and code a website?
@mental prawn i was do the learn at youtube

[nimble epoch]

flask or django @mental prawn ?

[modest shale]

my advice watch youtube first

:3

[mental prawn]

cuz i know the basics of python so i want to use my knowledge to do a website

flask or django @mental prawn ?
@nimble epoch not sure

[nimble epoch]

flask is for beginners mostly but you can do a lot of thing with that and django is another popular one

[mental prawn]

which one is easy, free to use?

[nimble epoch]

both are free

and flask is easier

[mental prawn]

i heard that django is difficult to use

but flask is a bit easy for begginers

thank you for your help

[nimble epoch]

thanks #_#

[narrow jasper]

guyz i have question regarding django forms

can anyone help me with it

i have template with form

with two submit buttons for different purposes

both requires post data for calculation

so how do i differentiate it

[stable kite]

@devout coral what's your opinion about this
#web-development message

[devout coral]

I would say yes for JSON and hold out on csv until someone requests it unless you have spare time. Won't hurt to have but I do not think it is essential.

[near bison]

guyz i have question regarding django forms
@narrow jasper a way is to have different values for each submit button and check what the value of button is in the view.

<input type="submit" name="calc" value="add">
<input type="submit" name="calc'" value="sub">

do this and check what the value of calc is in the view @narrow jasper

but that doesn't work

so idk

[tardy heron]

me neither :]

[native tide]

Guys

Can I get help from here?

Please someone say yes

@native tide I can try to help maybe

[warm igloo]

@native tide Instead of asking for help or asking to ask, just like .. ask

state the problem, we'll see if we can help

[native tide]

Okay it's just because this

do you know what's ngrok?

[warm igloo]

yes

[native tide]

https://webdevdesigner.com/q/ngrok-errors-502-bad-gateway-308720/

[warm igloo]

I don't use it anymore but yes

[native tide]

I'm having same problem as the link I sent

error 502 bad getway

[warm igloo]

do you know your service is running

[native tide]

What do you mean

I'm new to it

Please don't be angry

Just try and understand

[warm igloo]

not angry, did I come off like that?

So, you wrote a python app running on a port of some sort (let's say 5000).

Flask? Django? Let's start there so I can help more.

Here's how ngrok works with one of those:

1. I make a Flask app that listens on port 5000
2. I use ngrok to do their port forwarding magic so that http://blahblahblah.ngrok.io forward internet traffic to my localhost:5000

If you don't know #1, #2 isn't forwarding anything.

[native tide]

Look,

I use ngrok

[warm igloo]

sure

[native tide]

I'm making a collaborative note taking app. But I just want to know which would be a better idea...

On the dashboard, there is a sidebar which lists the notebooks linked with a user's account. Once they select a notebook, it will show the notes associated with that notebook.

Should these notes be rendered in the same sidebar? Or should they be rendered in an adjacent div?

I'm thinking of rendering the notes in the same sidebar, and removing the notepads once something is selected.

[onyx crane]

I think you're more concerned about design decisions. As far as im concerned this is more about technical questions

[swift sky]

yes make seperate applications and merge them
@toxic flame was this in response to me

[onyx crane]

Django Channels:
All tutorials and blogposts always put Django with Docker and Redis. Is there a particular reason for that or is it possible to use django channels without it ?

[civic kiln]

hi guys need some help here

Briefly select two transaction handling criteria that they may want to evaluate in selecting the appropriate RDBMS, and provide a comparison of how Oracle and PostgreSQL support these features

i found some answers but not sure, the first one is ACID
A- Atomicity
C - Consistency
I - Isolation
D - Durability

the second answer is from my notes
Backup, checkpoint and recovery facilities
–Database log facilities
–Concurrency methods and granularity
–Deadlock resolution strategies
–Advanced transaction management
–Parallel/distributed query processing

thats the question 👆 but dont know how to compare, im not getting the answers

anyone willing to help

[nova shadow]

Is it possible to update a flask blueprint without restating the whole application?

[native tide]

Hi, so i am using this to make animation on button click. However the button can only be clicked once. The second time the animation doesn't appear.
Its because the clicked class is added to the button, if this is removed then it can be clicked again? How could i change it so i can achieve this?
https://codepen.io/MinzCode/pen/pogqVVX

[mint folio]

You can always remove a class, from an element, which would fix that.

[native tide]

yo

is it a way to see how much percentage an action in django has taken?

and send it back to frontend?

example this is started with a put request

---->Last visit for 195506055044 remain at 2019-12-13 00:00:00+01:12, with 9.328641413095976% done

how can i get the 9.3

alright thanks

@native tide is your output like this each time?

like same format?

@native tide DRF and return JSON I guess

[wanton tulip]

Hello #web-development , I got a question relating to "cursor.execute()". I think I am a little stuck over here: cur.execute("SELECT id FROM persons WHERE id LIKE (?)", (id)) I've seen a lot of examples online, where they show something with the question mark and with the percentages like: (%id) although I can't get my head around it.. Can someone please give me the right directions on what I do wrong? Thanks in advance.

[mellow granite]

(id,) ?

[wanton tulip]

Hello, @mellow granite I am sorry, I don't understand your answer.

[mint folio]

@wanton tulip It's known as a parameterised query. It's a way of pre compiling the SQL statement so that all you need to supply is the parameters. It protects from things like SQL injection too. So the ? is just a placeholder for the parameter that you will pass there. There's more to it that this but that's the basic for this channel.

[mellow granite]

Hey I think you should put a comma after the id in parantheses

[wanton tulip]

Oh yes, thats what I read, because of injections and stuff. @mint folio Thanks for your wide answer.

@mellow granite But If I dont add any more, why would I need a comma? If id is the only value?

[mint folio]

And try your query like this:
cur.execute("SELECT id FROM persons where id like ?", ('%'+id+'%',))

You add the comma because the function expects you to pass a tuple

[mellow granite]

I don't really remember the reason, sorry

Oh yeah !

[mint folio]

(123) is an integer whereas (123,) is a tuple of 1 element.

This way the placeholder ? can be replaced with the first element of this tuple

[wanton tulip]

aahh! Thank you very much for your example code and answer. So this would be the most secure way of using it, right?

[mint folio]

Secure from SQL injections yes

[native tide]

Can you guys please let me know in what situations you would use raw SQL (like that), rather than an ORM?

[wanton tulip]

I don't know why, but the ('%'+id+'%',) part looks a bit cumbersome.. Am I right? Or are there other solutions for?

[mint folio]

@native tide If you use a mixture of Orms and raw SQL, then generally the raw SQL will be used for when you want better performance from certain queries.

[native tide]

Ah okay

Does working with raw SQL help you learn specific DBs, like postgres?

[mint folio]

SQL is just query language, to be used with databases

Will it help? It will definitely make you understand more on how they work.

[native tide]

Yea I guess that was what I was going for. Alright, thanks for that. I'll do some internal debating...

[quick cargo]

Tbf most orms now can write faster sql than most devs who don't actively work in it

Sure you can write raw sql to apply indexes and the likes but equally you can set that up on le orm as well if you're a orm user

[native tide]

I need help

Someone understand in port?

and ngrok

[wanton tulip]

@mint folio Hello, by using your example it's returning this example cur.execute("SELECT id FROM persons where id like ?", ('%'+id+'%',)) TypeError: can only concatenate str (not "int") to str What does he see as an int here?

[mint folio]

Then your id is an integer so you must convert it to a string

[wanton tulip]

Oh.. ofcourse! haha sorry..

[mint folio]

Cast it to string

str(id)

[wanton tulip]

Thank you! 🙂

[torpid pecan]

What is the best way to deploy a Django server?

Can u use something like blue host?

[devout coral]

@torpid pecan Yes, blue host should work.

[native tide]

Am I the only one that people dont answer my questions..

[acoustic oyster]

I do not see your question

@native tide feel free to ask your question. It looks like you asked if someone knows a specific tech, if you have a question about web dev, feel free to ask it here.

[native tide]

ngrok

Do you understand on it

I mean I made a localhost link using a port, but now the link is stuck on that port forever

I want to change the link from that port

Like for example

http://localhost:4444

This port contains a link, but this link is stuck on port 4444 forever

I want to change that link from the port

[acoustic oyster]

Hmm, I am not familiar with Ngrok, but I did find this https://stackoverflow.com/questions/36018375/how-to-change-ngroks-web-interface-port-address-not-4040

You will likely need to restart the service though.

[native tide]

What do you mean?

[acoustic oyster]

If you are already running ngrok on one port, you need to restart and change the port.

[native tide]

Yes, how to change it is the question

[acoustic oyster]

The article i sent shows how to set up a config file

Or the command is ngrok http <your port here> to run it using http on a specified port. https://ngrok.com/docs

[native tide]

Yes I'm following it

Or the command is ngrok http <your port here> to run it using http on a specified port. https://ngrok.com/docs
@acoustic oyster This is not my problem, my problem is that I want to make a HTML file listen to the port

[acoustic oyster]

I am not familiar with ngrok, to make your html listen to a port and accept events, I would use some sort of backend, such as Express.JS or django/flask

[native tide]

flask

yes

But how exactly..?

[acoustic oyster]

Are you using flask?

[native tide]

It's actually coded in bash

[acoustic oyster]

I am confused. Are you trying to change the port ngrok is running on? Or you are trying to point it towards a web app you have?

[native tide]

I'm trying to change the port that the code port

[acoustic oyster]

Well, if you programmed your webserver, you should have specified what port it is listening on. Then you would run ngrok with whatever port your webserver is listening on. From what I can see from the docs.

[native tide]

So it's specified inside the script?

[acoustic oyster]

Your webapp/webserver should be listening on a specific port that you probably would have to specify, depending on what framework you may be using, that port may be automatic and may vary

[native tide]

Can I change the port?

[acoustic oyster]

You should be able to. It should depend on your webserver/app. I am not sure what stack you are using though.

[native tide]

Inside the script?

[acoustic oyster]

I am not sure.

Typically you would use environment variables and specify the port when you run your webserver.

The default ports are 80 for http and 443 for https

What are you using as a webserver?

[native tide]

can I type netstat

to check what port its listening?

[acoustic oyster]

Hmmm, I think netstat may show that. You should really be specifying in your server.

What webserver are you using?

I.e nginx, apache, gunicorn?

[native tide]

ngnix i think

no listening

[acoustic oyster]

Well, you need to configure nginx to listen to ports 80 and 443. As well as setting up your firewall to give permissions.

It sounds like you just want to host static html, so you need to tell nginx where to find those static files and you probably need a config for them.

You would be better off following a tutorial for this.

[native tide]

Look, it's already listening to the port

but i need more HTML links to listen to the port too

[acoustic oyster]

Well, html does not "listen to a port"

Servers listen on a port to redirect traffic to html.

So in order to add html, you just need to add more html files whereever you need them

[native tide]

I already have them

[acoustic oyster]

If you already have the webserver setup and serving html where you expect it, then you just need to use "hrefs" to link to other html, or manually enter the path into the browser to see a complete website.

[native tide]

If you already have the webserver setup and serving html where you expect it, then you just need to use "hrefs" to link to other html, or manually enter the path into the browser to see a complete website.
@acoustic oyster But HTML Doesn't load pictures..

And stuff like that

How can I make HTML load pictures?

How I can make a localhost public?

[vestal hound]

How can I make HTML load pictures?
@native tide what do you mean HTML doesn't load pictures

[native tide]

@native tide what do you mean HTML doesn't load pictures
@vestal hound That's what I mean.

[vestal hound]

@native tide well, most websites use HTML to display images, so...

how are you trying to do that?

[native tide]

I saved the website as .index file

And it didn't load the pictures..

[vestal hound]

I...am not sure what you're saying

like you saved the HTML of another website?

one that exists on the Internet?

[native tide]

I noticed Facebook is the only website that doesn't load the pictures when you save it as .index

[gaunt marlin]

you said you used nghix right? did you served your static files with it ?

https://docs.nginx.com/nginx/admin-guide/web-server/serving-static-content/

[narrow jasper]

@narrow jasper a way is to have different values for each submit button and check what the value of button is in the view.
@near bison can you explain me that .. ping me whenever you r free

[jade salmon]

After python what should i learn for web dev? ping me wid reply

[mint folio]

@jade salmon Web development consists of front end and back end. Python is only for backend so you will need to be familiar with front end technologies (the bare minimum is HTML and CSS), and some JavaScript would also help.

[jade salmon]

Oh

So, should I pick up JS next?

[gaunt marlin]

yes JS is also used alot in frontend and backend too @jade salmon

[jade salmon]

Oh, that's nice!

[sweet yarrow]

How can i send variable from a flutter app to python?

[bronze oak]

Just a general question, any of you django developers ever used any JS frameworks/libraries like React or Vue as front end with django?

[dapper tusk]

I used alpine.js, but generally with the frameworks that require compilation you just make an API in django and serve the react/vue website as static files

[bronze oak]

So you mean, front end frameworks make api calls for any backend stuff and the api itself is written in Django

[dapper tusk]

yes

[bronze oak]

Actually, I am new to Django, have been thinking of some project ideas to work on using django and had this thought if we could do, what i just asked you.

[gaunt marlin]

i tried to serve React spa with my django server once, the url paths of those 2 really conflicting with each other. I would just use django as an api for React SPA

[buoyant shuttle]

hey guys, for some reason my static css file is not rendering it?

even when i loaded static

[gaunt marlin]

@buoyant shuttle which framework are you using ?

[buoyant shuttle]

django

My css worked in one of my templates

[gaunt marlin]

did you set debug=False ?

[buoyant shuttle]

and in the other it didnt

i dont think so, lemme check

[gaunt marlin]

just check what it's currently being set right now, don't change it

[buoyant shuttle]

CommandError: You must set settings.ALLOWED_HOSTS if DEBUG is False.

this what happened

when i set it to false,

it was true before

for some reason the css rendered, once i set it back to True

[gaunt marlin]

oh then you was on development environment

don't change it to False

[buoyant shuttle]

ok

thanks alot @gaunt marlin

[gaunt marlin]

i just want to know

can you post the static related settings in your settings.py ?

[buoyant shuttle]

yeah

[gaunt marlin]

ok i see, can you post the html templates code where the css is not applied ?

just the lines with {% static '' %}

if you wrote it correct in your template it should be like this

{% load static %}
<img src="{% static 'my_app/example.jpg' %}" alt="My image">

make sure that all your css is in a folder name static

in the root of your project

[buoyant shuttle]

This is my base template, my css worked but i changed the color to black no effect

[gaunt marlin]

oh then try to restart your server

[buoyant shuttle]

ok

[gaunt marlin]

you running with python manage.py runserver right ?

ctrl + c on the running terminal to stop the server

and run it again

[nova nacelle]

@buoyant shuttle Also use ctrl f5 to reload the page

[buoyant shuttle]

it worked when i used ctrel f5

@buoyant shuttle Also use ctrl f5 to reload the page
@nova nacelle Thanks

by bg color is back to black, just testing to see if it will render.

[nova nacelle]

Yeah, it clears the browser's cache on reload.

[buoyant shuttle]

ah ok

learned something new today 🙂

[gaunt marlin]

yeah browser save previous css loaded so ctrl+f5 clear the cache

[nova nacelle]

@nova nacelle Thanks
@buoyant shuttle Np

[vernal furnace]

yo guys, https://gyazo.com/421f63150c6267355fedd820d561fe5f

[wanton tulip]

wadddupp

[vernal furnace]

so this my post creating form

what I want to do is to add a submit buttons with integers to the field list

class PostCreateView(CreateView):
    model = post
    fields = ['title', 'content']

for example a submit buttons with the number 3 - 4 - 5 just under the content

[wanton tulip]

Why would you want that?

[nova nacelle]

@vernal furnace What would that do?

[wanton tulip]

^^ haha

[vernal furnace]

I want these to be the number of bedrooms,bathrooms etc

so when I create a search bar later on the search engine will search for these variables

I'm not sure if i'm doing it right tho

:c

[nova nacelle]

Forget that method for now, and explain me what you exactly wanna do.

[vernal furnace]

Lemme send you a picture

[nova nacelle]

you can simply add a field that says no. of bedrooms in your model

[vernal furnace]

can u show me how to do it

[nova nacelle]

wait

[vernal furnace]

All I want to do now is the beds(just one field)

[nova nacelle]

bedrooms=models.CharField(max_length=2, choices=(("2","2"),("3","3"),("4","4")), null=True, blank=True)

add this to your model

and then add the field bedrooms in your view

@vernal furnace

[vernal furnace]

 bedrooms=models.CharField(max_length=2, choices=("2","2"),("3","3"),("4","4"), null=True, blank=True)
                                                                                                        ^
SyntaxError: positional argument follows keyword argument```

[nova nacelle]

blank's in the same line

wait

@vernal furnace you missed brackets for choices

[vernal furnace]

Bruh

lof

❤️

[nova nacelle]

bedrooms=models.CharField(max_length=2, choices=(("2","2"),("3","3"),("4","4")), null=True, blank=True)

@vernal furnace read it properly

[vernal furnace]

https://gyazo.com/662da107f449f094a97f8e4e71c037c0

Dude this is so cool

Wait can I make it more user friendly?

like just buttons

[nova nacelle]

This is for posting a post. It's fine... on the user's side you can add buttons as filters

[vernal furnace]

oh nice

Thanks again, lemme go finish the tutorial

[nova nacelle]

Alright, bye.

Thanks again, lemme go finish the tutorial
@vernal furnace Np.

[red perch]

Hi, im working on a project what can compare TechProducts using webscraping. I created the website using just plain html and css but i wanted to do the webscraping using bs4 because i did not know how to do this with javascript. After i did this i tried Flask for the first time so i can render my html template using render_template but when i do this the localhost "server" keeps loading, if i remove the render_template and just return text it loads instandly. ```py
from flask import Flask, redirect, url_for, render_template

app = Flask(name)

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

if name == "main":
app.run(debug=False)```This is my simple Flask code. And yes index.html is in the folder templates

[proper owl]

Try creating your app like:

app = Flask(name, template_folder='templates')

[verbal linden]

I have a function that gets every filename from a directory, reads it, converts it to base64 and then returns it into an <img> tag that is served to the user, but it only returns 1 image, and not all of them, but if I have the function print every filepath, that works fine.

def getPosts():
    for filename in os.listdir(image_dir):
        if filename.endswith(".DS_Store"):
            continue
    else:
        with open(os.path.join(image_dir + filename), "rb") as img_file:
            image_data=(base64.b64encode(img_file.read()).decode(charmap))
            image_element=("""<img src="data:image/png;base64, {}">""".format(image_data))
            image_container=("""<div class="image">{}<br><p>filename: {}</p></div>""".format(image_element, filename))
            return image_container```

```python
image_list=("""<div class="images">{}</div>""".format(getPosts()))```

yes I'm aware it's horribly inefficient, but for the purpose it's serving and the http.server module I used, it's what I'll have to put up with

[near bison]

How are svgs made ?

[native tide]

Hey guys I need help in Django project
I thought to develop a chat application with Django
So What front-end I can use for it
Pls help me it is my first project

[verbal linden]

How are svgs made ?
@near bison complex math

[near bison]

Damn

@verbal linden Are you sure ? You mean all those symbols and logos in svg out there are made with code. i don't think so

[verbal linden]

math, not code

[near bison]

You can't just draw ?

[verbal linden]

that's why you can rescale them without losing quality

and why you can't convert a png to an svg(?)

[near bison]

Because it's vector

[verbal linden]

yes

[near bison]

I made some simple svgs in figma. so i don't think it's just math. there must be way's to draw it or something

[balmy stag]

@native tide You need to make your chat interactive so you'll need JS. You can go old school and use plain JS or jQuery, but it's highly recommended to use a JS Framework. The most famous are Angular, Vue and React (React is the most popular).
There are 2 main solution to use Django with a JS framework : Django serves as an Restful API and the front is independant, or you can integrate the compiled JS in your Django template with the help of webpack

[native tide]

@balmy stag Thank you

so it will take couple of months to complete

[near bison]

What are some apps (open source) to work with SVGs ?

Create , Edit etc

[native tide]

are you in windows

or linux

[dapper tusk]

inkscape is the most popular one

[balmy stag]

Yeah it's a common projet but not the easier

[native tide]

I agree

for @dapper tusk and @balmy stag

[near bison]

linux

[native tide]

ok

then Inkspace

or check this out

https://colorlib.com/wp/free-svg-editor-tools/

[near bison]

what is that device you use to draw called ?

[native tide]

I don't touch that part

because learning backend

[mortal mango]

does anyone know if you can put asp.net files on GitHub Pages?

[near bison]

I don't think you can. it's just for static documents as far as i know

[native tide]

yeah
@buoyant shuttle your python file should prolly be called main.py, but also the main html file is index.html not main.html

[jolly bone]

does anyone know if you can put asp.net files on GitHub Pages?
@mortal mango are you asking about blazor, or the db connection and alll?

[cold haven]

hi

[nimble epoch]

@cold haven hi

@limber edge im using flask_sqlalchemy but i have no idea about your question but in the same site that youve posted there was a solutionmaybe thatll help

[mortal mango]

@mortal mango are you asking about blazor, or the db connection and alll?
@jolly bone just a static .aspx website

[jolly bone]

Static sites are possible, but any dynamic content is not hosted by Pages

I'll suggest you see this guide

[swift sky]

hello

im trying to figure out how to pull multiple fragments into my html

basically, i have a webpage that gets updated by using mysql queries

currently i had only one section that needed to be updated

I was going to now add another section, using a different query

I thought that I could just duplicate the code, this didn't seem to work

@app.route("/")
    @login_required
    def staffdashboard():
        connection = db_connection_content()
        cursor = connection.cursor(pymysql.cursors.DictCursor)
        sql_query1 = "SELECT date_format(load_date, '%m-%d-%Y') as the_date, content from notification_content order by load_date desc limit 5"
        sql_query2 = "SELECT date_format(load_date, '%m-%d-%Y') as the_date, content from roll_call order by load_date desc limit 5"
        cursor.execute(sql_query1)
        cursor.execute(sql_query2)

        data1 = cursor.fetchall()
        data2 = cursor.fetchall()




        try:

            fragment1 = render_template_string('''
            
            {% for item in data %}
                <p class = "notification">{{ line }} </p>
                <p class = "load_date">{{ item[ 'the_date' ] }} </p>
                <p class = "content">{{ item[ 'content' ] }}</p>
            {% endfor %}
            ''', data=data1)

            fragment2 = render_template_string('''
            
            {% for item in data %}
                <p class = "roll_call">{{ line }} </p>
                <p class = "load_date">{{ item[ 'the_date' ] }}</p>
                <p class = "conent">{{ item[ 'content' ] }}</p>
                
            {% endfor %}
            ''', data=data2)

            return render_template("staffdashboard.xhtml", dict_to_be_passed=parse_311_sitemap(load_articles()),
                                   fragment=[fragment1, fragment2])```

how do i refference multiple fragments in my code

fragment=[fragment1, fragment2] is this viable?

because it seems to be placing the same fragment into both divs

<section class="hero is-info welcome is-small" style="height:200px; ">
                    <div class="hero-body">
                        <div class="container">

umm

so just the order

testing now

so

that didnt help, but basically it's placing query 1 in both divs

maybe i need to close the cursor

the content of this cursor.execute(sql_query1) data1 = cursor.fetchall()

<section class="hero is-info welcome is-small" style="height:200px; ">
                    <div class="hero-body">

here

the goal is to have query 1 go to the first div and query 2 go to the 2nd

yea

but idk much about fragments, idk what to even google

so idk if i can just change the name

how would you refactor it

i need to redo the whole thing tbh

i need to learn about blueprints

and {{fragment[1] | safe}} where you want fragment2
@limber edge this worked

blueprints is nice, but really only practical for larger sites imo
@limber edge this is the direction im headed

for your database stuff
@limber edge yes i have to do a major refactor, right now im not using the orm

thank you for your help

Is it stupid for me to be running two backends for my website? I am using Node.JS to run the API and Flask to fetch and process data from the API

[quick cargo]

yes thats a pretty dumb idea

[granite mirage]

@reef rover your question was inactive, what happen if you run rq worker high default low ?

[reef rover]

@granite mirage it just says listening on those queues

[granite mirage]

and you visit that path on browser, and no task got sent?

[reef rover]

The task gets queued but the worker does not start it

[granite mirage]

hmm idk...this one is the closet to your https://github.com/rq/rq/issues/758. the last comment on there is to dequeue and enqueue again.

[reef rover]

Seems like a bug

[silk gorge]

Does anyone have any ideas on how I could make the image on the left inherit the height of its sibling on the right using CSS grid?

[native tide]

stackoverflow is your best friend for those type of Qs

[kindred schooner]

Just use px

like img {height:20px} and p {height: 20px} you can just use some Javascript (or Python) to change a variable.

[devout coral]

@silk gorge Show me the snippet of how you have your html set up?

Just the parent and everything inside.

[cold haven]

Set it in a parent div container and set children at relative height is what I would do.

[kindred schooner]

That would work.

Why is there a web-development channel in a python server?

[cold haven]

Django probably

[kindred schooner]

Oh.

[cold haven]

It's a python framework

[kindred schooner]

Ik,

I just think it would probably be more supported, if it's a Python framework.

[devout coral]

What would be more supported?

[quick cargo]

there are loads of Python web frameworks

FastAPI
Sanic
Starllette
AioHTTP
Japronto
Tornado
Flask
Django
apidora

thats just a small list :P

[swift sky]

how do you guys handle wtforms validators and inherittence

like

class PhoneSurvey(FlaskForm):

    email = StringField("Email", validators=[Optional()])

    terminal_number = IntegerField('Terminal number', validators=[Optional()])

    #pandemic?
    was_this_a_pandemic_related_call = SelectField('Was this a Pandemic related call',
                                                   choices=[('yes', 'Yes'),
                                                            ('no', 'No')],
                                                   validators=[Optional()])
    #pandemic topic?
    what_was_the_call = SelectField('What category was this call', choices=[('',''),('get_food', 'NYC Get Food'),
                                                           ('covid_test', 'COVID-19 Testing'),
                                                           ('remote_learning', 'Remote Learning'),
                                                           ('other', 'Other')], validators=[Optional()])

    #did you resolve this call [APPLIES TO: PANDEMIC AND NON PANDEMIC]
    was_the_inquiry_resolved = SelectField('Was the inquiry resolved', choices=[('yes', 'Yes'), ('no', 'No'),
                                                                          ('other', 'Other')], validators=[Optional()])

    #were you able to
    submit = SubmitField('Submit')

class PhoneResults(PhoneSurvey):
    start_date = DateTimeField(label='Start Time (mm-dd-yyyy)', format='%m-%d-%Y %H:%M:%S', validators=[DataRequired()])
    end_date = DateTimeField(label='End Time (mm-ddd-yyyy)', format='%m-%d-%Y %H:%M:%S', validators=[DataRequired()])```

basically i have my survey, and i have my results (which is a class i use to pull data into xls and send to user)

and as u see my results inherit from my survey

but if i put in some DataRequired() validators in my survey, i am not able to actually download the report, because well i guess PhoneResults is expecting required data that is not being input by the reports users/since in my view function this is not a field that I actually use (in the reports page)

i believe there might be some OOP principles to help with this

but i was curious if anyone had suggestions

[native tide]

So if you have the DataRequired validator, and even if you provide data in that field, it doesn't submit?

[swift sky]

no so for example

the phone results class, the variables in there, those are the only things i ask from my user to input

so if i put a data required under some variables in PhoneSurvey i can't download the PhoneResults report, because I've inherited DataRequired() validators

and my end user who is trying to use PhoneResults to pull the xls report, does not actually need to input values for the PhoneSurvey, but because there are DataRequired() validators which are inherited from PhoneSurvey the xls file wont load.

i hope that makes sense

Django: I have a user logged in, they want to enter personal info about themselves into a table in the database, they should only create and submit a max of 1 time, is that a one-to one relationship? That is not with a foreign key correct? The other tables I could use a foreign key because they can enter posts multiple times?

[quiet comet]

use a boolean field, if he create one then true, if not false

@plucky tapir onetoone field

[finite flame]

is python a good option for backend dev?

[plucky tapir]

@vestal hound thanks. Would a one-to-one prevent the user from making another post to that table or I have to check that some other way? Through views possibly

[shut marten]

?poll

[indigo kettle]

@plucky tapir onetoone field ensures that there is only one related object

another one will not be allowed to be created

[cold socket]

Anyone know how to get around circular import errors?

ImportError: cannot import name 'Hospital' from partially initialized module 'app' (most likely due to a circular import) (/root/Tactical/app.py)```

[chrome onyx]

If you import a module that imports the main file, it will cause a circular import error

[cold socket]

Hmm why can't I import 2 files to each other?

[chrome onyx]

Like if you have import hi in one file and in hi.py you have import main, then it will import hi, which will import main, which will import hi, and so on and this causes an error

That's why you usually have one main file with all the variables and separate files for classes

And those class files usually don't import anything from the main file

[cold socket]

Oh I see the problem

[chrome onyx]

This has happened to me a lot, so I would just say combine both files

Unless you can somehow make Hospital.py work without importing from app.py

Good Luck!

[cold socket]

So Hospital is a class (table in SQLite) in app.py

And im trying to access it in another file

So I imported it from app. But I also use functions from the other file in app.py

[chrome onyx]

Is app.py importing that "other file"?

Oh yeah

[cold socket]

So yeah I import them in each other

yep

So I should just take everything in the second file and put it into app.py

[chrome onyx]

That happens to me a lot when I try to create a new file for my db.Model class when using SQL... you just have to move the other file to app.py, I can't think of another way

[cold socket]

Yeah I agree, ill merge it into app.py

Hopefully this resolves my problems

[chrome onyx]

Good Luck with the rest of your project!

[cold socket]

Thank you kind sir!

[still kite]

Hey guys what is a better framework django or flaskl?

[chrome onyx]

Depends on what you want to do

If you want to code a simple website

Use Flask

[still kite]

Full Stack Web Development

[chrome onyx]

If you want an industrial-scale website with great organization and multiple features...

Use Django

[still kite]

I want to become a full stack web developer that's why

[chrome onyx]

I would recommend starting off with Flask then... if you haven't done web dev before

[still kite]

and is there any other framework to make a rest api

[chrome onyx]

I don't know much about Rest APIs, so someone else can help you with that

But if you haven't done web dev before, I would recommend you get started with Flask

It has some cool features and works really well even though it's very simple

[still kite]

I know that is why i like rest api's

[warm igloo]

FastAPI is great to try too. We’ve been using that instead of Flask lately.

{% if object.auther == user %}

yoo why its not working

😦

The server is working just fine, everything is working but the buttons for update and delete doesn't show

[vernal furnace]

what do u mean

intendation looks fine in ide

[late gale]

oh ok let me look again

do u have any errors ?

[vernal furnace]

nope

[late gale]

so the problem should be in the {% url % }

let me see

[vernal furnace]

it looked like {& url &} at first but I fixed it

[late gale]

isnt it corey's tutorial ?

it looks very familiar to me

corey schafer

[vernal furnace]

yea

well its not working

[tardy heron]

Why can't I send mail using gmail? I already sent mail using sendgrid, but my email is on a blacklist, so i made a gmail account to send, but it hangs. Same with my other account.

my mailbox doesn't get any mail from them 😉

[vernal furnace]

OHHH

FINALLY

[late gale]

=,=

haha

yea happens

[vernal furnace]

but why the ide didn't tell me about it

[tardy heron]

When I added gmail to thunderbird it asked me about it on my phone. Now it doesn't ask. Is there some thing about this I dont know about. Like having to authorize an app using my credentials

Hi Again,
I added another field for my requirements to post here it is:

bedrooms = models.CharField(max_length=2, choices=(("2","2"),("3","3"),("4","4")), null=True, blank=True)

and that one is in my views.py

class PostCreateView(LoginRequiredMixin, CreateView):
    model = post
    fields = ['title', 'content', 'bedrooms']

it gives me this error

[agile wedge]

Hello guys. Im making simple website in flask. When i enter name and classroom in POST method and click submit i get error: return render_template("elo.html", ucenik=ucenik)
NameError: name 'ucenik' is not defined.

Here is main piece of code. I reckon solution is simple i just cant find it.

[meager pecan]

hi guys i am beginner i need a friends or a team that have the time and the ability to help and share mme to expand #I-need-help 🙂

[tribal python]

@agile wedge you have a scope error, ucenik is only defined in the home function

not the elo function

[agile wedge]

How do i make elo function "see" ucenik from home function?

[tribal python]

define it outside of the function.

use a database or some basic store for the objects

@meager pecan if you have a question, feel free to ask in the appropriate channel, or see #❓｜how-to-get-help if you need some targeted help with something

[meager pecan]

can i ask a question? how old are you @agile wedge & @tribal python

since you are very pro!

i am 16 years old and learning python ana java in school but i need to expand more

[agile wedge]

@tribal python Ok ill try to implement basic database. tyvm

[meager pecan]

i am beginner!

[tribal python]

23 here

How can I use JS to get data from django backend? or a way to pass data from template to a view in django so that the view can update it and send back

[late gale]

@empty saffron use sterilizers

https://stackoverflow.com/questions/10358803/is-it-possible-to-use-javascript-to-get-data-from-django-models-db

that might help i was going for the same problem and that helped me

[empty saffron]

I don't want data from db

I want it from a function

I want to pass data from user to a function in the backend and get the result and display it

Basically, the user will enter 2 fields in a form and press "Run" then it should feed that data to a function in the backend and get the results and add a row in a table

is there a difference if i code on pycharm or python app it self?

[late gale]

and i have this error

@mental prawn nope

Pycharm will let you do a virtualenv for your project which is something cool for your package management

[tardy heron]

@mental prawn you don't mean the interactive interpreter?

[mental prawn]

what i mean is that for example if i want to make a website there is no difference if i use pycharm or some other editing apps

[late gale]

nope there is no difference

but in web developement i highly recommend vs code

[mental prawn]

visual studio

[tardy heron]

no theres a lot of choises. Some have more features than others

[late gale]

vscode = Visual Studio Code not Visual Studio

because it's very fast and doesnt consume much ram

unlike Pycharm

though pycharm has amazing features

that vscode doesnt has

[tardy heron]

vscode has plugins, but i found pycharm easier to use. Don't know how others feel

[late gale]

it depends on everyone's perspective

[placid vale]

heared pycharm first time o.o

[late gale]

If u are working on a big projects i would recommend pycharm

[mental prawn]

well when am coding on pycharm when i right some letters or words it pop ups some other words for example if i right pr it will show me different stuff to use

[late gale]

I only use vscode for websites

[placid vale]

lol firstly i used notepad

[tardy heron]

eww

[mental prawn]

notepad ++?

[placid vale]

nah simple 😛

[mental prawn]

idk how to use that cuz am used to pycharm

[placid vale]

[late gale]

[placid vale]
