#

Fyi, I'm using Jsonify, do I need to craft some stuff to get this working fully?

elder nest
#

how would I run a form when a page is loaded

#

I tried this but it didn't work ```{% extends 'layout.html' %}
<form action="/selectserver" method="post" id="foo">
<input type="hidden" id="code" name="code" value={{ code }}>
</form>

print session to see its keys / data structure

#

the issue is that 'email' is not a valid key

opaque rivet
elder nest
#

I am changing it to a post

#

so yeah

opaque rivet
#

yeah, so tell me again why you need that in the template?

#

you can send requests from the view

elder nest
#

how would I do that?

opaque rivet
# 
import requests
requests.post("your_url", data=your_data)
elder nest
#

@opaque rivet it says cannot use method @app.route('/codetopost', methods=['get']) async def codetopost(): code = request.args.get('code') code = str(code) return await requests.post("/selectserver", code=code)

opaque rivet
# elder nest <@!812098613450506351> it says cannot use method ```@app.route('/codetopost', me...

that just sends a HTTP request, you don't want to return it.
read a tutorial on it:
https://realpython.com/python-requests/

Python’s Requests Library (Guide) – Real Python

In this tutorial on Python's "requests" library, you'll see some of the most useful features that requests has to offer as well as how to customize and optimize those features. You'll learn how to use requests efficiently and stop requests to external services from slowing down your application.

elder nest
#

@opaque rivet this is what I see @app.route('/codetopost', methods=['get']) async def codetopost(): code = request.args.get('code') code = str(code) requests.post("/selectserver", data={"code":code})

#

it still doesnt work

opaque rivet
elder nest
# 
async def selectserver():```
zinc marten
#

define "will not work"

I'm smelling "forgot to set a secret key" in the answer.

#

does your template read the flashes?

#

yes. Flash just adds a tuple to a set that is retrievable

elder nest
#

ok now it accepts it what should I put for this

# 
    code = form["code"]```
#

to accept the data @opaque rivet

zinc marten
opaque rivet
# 
{% for flashed_message in get_flashed_messages() %}
  {{flashed_message}}
{% endfor %}

It's something like this

#

do people still use templates in industry? or is it all moving to JS libraries?

zinc marten
#

In industry? Yes, absolutely.

opaque rivet
#

I wouldn't lean on templates so much though, I'd learn it make a project, and then move on to a frontend framework

#

You'd put that wherever you want your flashed messages to show, that's up to you

distant charm
#

@opaque rivet sorry for the ping but would using a try and except for the above issue would be a normal thing right? or would it cause any issues

elder nest
#

@opaque rivet what would I put to accpept the data, also its saying its a get thing

zinc marten
native tide
#

hi, sorry for interupting but how can I send data from a bootstrap dropdown with the form so I can read it with flask in python

zinc marten
#

I know a surprising amount of folks who use templates to generate the frontend.

elder nest
#

im just going to make a is this you page or some crap

zinc marten
opaque rivet
opaque rivet
zinc marten
#

My work blocks NPM and we have to vet every library version through.

elder nest
zinc marten
#

Templates reign supreme.

native tide
#

thanks

opaque rivet
#

No but really, you get nowhere the amount of features using templates as you do with a separate framework

#

Any DOM change without JS and your page refreshes... that isn't the standard for sure 🙂

zinc marten
#

Half our frontend tools are just perl/java with Bootstrap thrown on top

#

Fun fact: did you know that Amazon's entire shopping experience works without JS?

#

From what I've been told, it's 100% SSR with some light stuff on top for things like lightboxes and such

opaque rivet
#

Yeah that makes sense

#

I really like developing w/ React, and I've been getting into Next.js recently which supports SSR

#

There's a lot of hype with those technologies

zinc marten
#

oh, what's old is new again with SSR. it cracks me up.

opaque rivet
#

Yeah I've had no idea how to serve it from Django though

#

its pretty niche

#

need it for SEO which SSR is good for

real hare
#

If anyone is familiar with Flask routing, can they look in #help-falafel thanks

opaque rivet
#

server side rendering, as opposed to client side rendering

hey, how would i make 'from_user' and 'to_user' different from each other? So that a user wont make a comment on its own profile.

if user is owner of the post:
raise error

#

Can you show us the Profile model and the method that handles the comment ?

Are u using django?

#

If u are

#

Tou can use validators for model column

signal bronze
#

im still very new to flask so go easy on me. How can i distinguish between sign up and sign in?

<div class="NotSingedInBox">
    <input type="submit" value="Sign in" class="SignInBTN">
    <input type="submit" value="Sign up" class="SignInBTN">
</div>
heavy roost
#

Hey, is it possible to display django validation errors like the default ones? For example like this:

unknown.png
#

My current validation errors just return the debug page

#

how i handle validations currently: ```
class Comment(models.Model):
content = models.CharField(max_length=500)
date = models.DateTimeField(auto_now_add=True)
rating = models.PositiveSmallIntegerField(default=1,validators=[MinValueValidator(1,message="Rating value is too low."),MaxValueValidator(5,message="Rating value is too high.")])
from_user = models.ForeignKey(User,on_delete=models.CASCADE, related_name='from_user')
to_user = models.ForeignKey(User,on_delete=models.CASCADE, related_name='to_user')

def validate_different(self):
    if self.from_user == self.to_user:
        raise ValidationError(_('Both users are the same.'),code='invalid')

def __str__(self):
    return self.content

def save(self, *args, **kwargs):
    self.validate_different()
    return super().save(*args, **kwargs)

class Meta:
    unique_together = (('from_user', 'to_user'),

I'm dont have much exp with Django

But I will see the docs

I will take that is guide also.

#

I'm sorta new to django, what do you guys thing think is the best part?

#

The most useful part.

valid girder
#

I think a built-in ORM and robust API framework (DjangoRestFramework). Also a good html template engine built in, but then people use APIs now and render html in React frontend. Also Django has a long-running and great community (as is evident here) :p

I'm not a developer by trade but an accountant who enjoys coding and dev in my spare time and automating the boring stuff. Anyways, I am trying to showcase some of my coding work in the hopes of landing a job with a big accounting firm in the data analytics department. Was thinking of writing a django/react site that I can use for a blog post, showcase some work that I have done regarding automating accounting functions, resume page and so on. I would like the posts and articles to have have different components inline ['text', 'code snippet', 'text', 'image', 'text'], like how articles are written on real python. How do you define an object that can have these different types of output inline? Would markdown be the best route to go?

wispy quail
#

like with whatever python you are using to run your file

#

running pip bare wire leads to tons of simple confusions

@wispy quail Hi, sorry about that, I would like to select numeric value in my selection and return back , but unfortunately, it prompt me this error TypeError: ‘list’ object cannot be interpreted as an integer

wispy quail
#

o gives you {'name':1} the first time. so o['name'] gives you 1

cedar pasture
#

Hmmm nope it dint even return any value

wispy quail
#

using . notation works for dictionary?

wispy quail
cedar pasture
#

can show me the example @wispy quail ?

wispy quail
#

I just copy pasted your code and ran it

cedar pasture
#

I see

#

can you return numeric ?

wispy quail
#

well you asked for a list, you got a list

#

request.form['comp_select'] gives you the answer

wait a moment, actually I use this to another source code

maybe different scenario happen in my code

You can, but it's not standalone. There are other things you need to do. You can self-host and use an IP directly instead of a domain-name, but again, the internet will probably have more in-depth information

Hello
I'm new to flask and I was wondering, is it possible to shard an app ? For example if I make a big app, how would it be possible to divide my app to host it on multiple servers ? so the load would be lighter

#

I mean, are there ressources out there where I could learn about this ?

@twilit needle maybe you can make a seperate view/path for each functionality? Such as uploading files, or retrieve files/folders individually

Also, how is that recursive?

If you want to create a chain of DB entries you can use django signals

wind walrus
#

So in Flask SQLAlchemy I want to store a list of members in a group in a column

#

Would I use PickleType?

#

Or would I create a new table and do a one to many relationship?

worn mural
#

one to Many

#

This is the way you should go to when using SQL db's

#

You could give it a try to NON-SQL like Mongo ifyou would like to have a list

wind walrus
#

so when is pickle used?

worn mural
#

I would not use

#

Only for specif cases

#

when I would want to store some object

#

That woundt get to big or need to filter inside it

#

But I prefer not to use

#

In your case you really shoud build a new table

#

and do a one to many relationship

worn mural
wind walrus
#

Oh I see, thank you!

worn mural
#

I'm glad I could help 🙂

#

I will give one example that has nothing to do with Python when I would serialize an object inside an sql db

#

So in Minecraft servers you could write a plugin that would spawn some random items in a given location. Locations in Minecraft is an object with an X, Y, Z cordinate, so I would serialize this locations in a json: {'x':30, 'y':15, 'z':20} and save it inside an String column called location.

red umbra
#

hi guyz

worn mural
wind walrus
#

Ahhh I see

#

So you wouldnt even use pickle for that

#

you woud just jsonise it and put it as a String i see

bold hound
#

guys im trying to make a chrome extension (or anything that can work parallel in multible tabs) that clicks 2 coords on the screen. the site is made in unity, so no html tags for buttons. Is this possible in any way?

wind walrus
#

why wouldnt you use Pickle?

red umbra
#

i just really badly want speaking perms

worn mural
#

And is not safe

bold hound
#

i can click elements, but having issues with coord clicking

worn mural
#

You could overwrite by a mistake

#

all your users in the group

wind walrus
#

oh interesting okay

worn mural
#

And JSON is lighter then PickeType

#

But remember serializing list and putting inside an sql row is not a good practice

#

If you could create a new table, create it

#

Its easier, fast and safer

wind walrus
#

Yaeh i didnt know that

hallow yacht
#

got some question regarding json dictonary response

#

its 4 levels deep. And i got towards the last level.. but cant seem to get my data out of the next level 😦

worn mural
#

What is happening ?

hallow yacht
# worn mural What is happening ?

i get to the last level. and i checked for the type just to be sure. And it still is a dict.
{
"2160":{
"key1": value
},
but when i do for x in dict:
print(x)
i get 2160 back as value

worn mural
#

Are you parsing the json?

hallow yacht
worn mural
#

Try numbers[“2160”]

#

I think interating will return the key value

hallow yacht
#

its like that

worn mural
#

And you still need to decode it

hallow yacht
#

and goes on like 2162 , 2163 etc

worn mural
#

If you want to access data inside

#

Just acces via the key

#

For example

#

For x in numbers:
Print(numbers[x]

#

You wont get the values

hallow yacht
#

i need to loop over everything. and get values of a key inside 2160. Maybe i need to decode again ?

worn mural
#

Because you are interating over the keys

hallow yacht
#

aha

#

so i need to put in another dict ? And loop over that one or ?

#

im lost

worn mural
#

Noo

#

Ok so, tell me

#

what is the data of this value

#

How does it look like?

#

You could do something like

#

for x in numbers.items():

#

print(x)

#

it would return the dictionary inside

#

the key

#

So keys are a list ?

hallow yacht
#

could i dm you with the values ?

worn mural
#

sure

opaque rivet
reef oasis
#

No need to use list too. You can simply:

for key, value in your_dict.items()
  # 1st run: key = 2160, value = keys (dict)
  # 2nd run: key = 2161, value = keys (dict)

or

for item in your_dict.items()
  # 1st run: (2160, your_dict[2160])
  # 2nd run: (2161, your_dict[2161])

If your_dict[key] is a dict and you need to iterate over it, I suggest you create a function that iterates a dict recursively. Something like this:

def dictIterator(my_dict):
  whatIwantToSava = []
  for key, value in my_dict.items():
    if type(value) == dict:
      whatIwantToSave.append(dictIterator(value))
    else:
      whatIwantToSave.append(...)
  return whatIwantToSave

#

Who Can Help Me This Topic?

worn mural
#

Would be with websockets

#

You can listen to when the user connected

#

And when disconnected

#

Orr

wind walrus
#

how do i do it with tokens?

#

like auth tokens

#

also just to clarify, i only want a single tab to have access

worn mural
wind walrus
#

so even on the same user, different tabs shouldnt have access

#

oh django 😦

worn mural
#

Ohh

wind walrus
#

anything with flask?

worn mural
#

what are u usingw

#

?

#

An easier aproach

#

would be to get a timer

#

So maybe u think the user will spent 30 seconds do edit the profile

wind walrus
#

oh

#

timer is not ideal for this

worn mural
#

Okk

#

so websockets

#

is your way

wind walrus
#

somebody suggested using tokens

#

how would that work?

worn mural
#

I can't imagine a way of doing with tokens

wind walrus
#
  1. user A starts editing
  2. token is generated for user A and saved in user A browser
  3. user B tries to edit
  4. here, how would they check if user B can edit or not?
#

yeah

#

i couldnt either

worn mural
#

It would only work

#

if timer

#

for example

wind walrus
#

so just to explain my situation further

I have like a group project sort of thing where any group member can access and edit the form
i have a db to record the details of the form

i want to prevent conflicts, so i was thinking of storing a Boolean column in the db to keep track of whether someone is currently editing the page or not

so i would update it every time they access and leave the page

#

this was my first approach

#

(i copy pasted this message from another server so it kinda falls out of place but just to clarify)

worn mural
#

okk

#

so you will use websockets

#

The things you need to know

#
  1. User try to access the form
    -> You will verify if someone is using
  2. User access it, you create a connection via websockets and create one dict that stores the user that are editing and what form they are editing.
  3. If user quits the form, the connection will be shut then you remove them from the DICT
#

To verify just check if user acessing == user modifing in the dict

#

This is the aproach I would take

wind walrus
#

how about if same user starts accessing from a different device?

worn mural
#

It would owkr

#

work

#

but would be a problem, would ?

wind walrus
#

user acessing == user modifing in the dict

here do i compare the account?
if so then different device same login will double right

#

just gotta make sure the form is being edited and submitted only once so there is no conflict

#

even if same person is editing, i want to prevent them from accessing on another tab

worn mural
#

yess

#

So you need to create a token

# mortal mango how would I make a query in django to an external database that I have specified...

U can either use a db manager and let him decide which db to use and u do normal db queries like: users = User.objects.all() or you use the "using" parameter/function like so: User.objects.using("users").all() or for saving my_object.save(using="objects")

well literely none of those commands would work on windows... so

just go to your antivirus settings and see if theres any issues detected if youre worried but it shouldnt have done anything

dapper tusk
#

this really shouldn't have done anything, django isn't vulnerable to that

#

ok

tacit brook
#

the only way that would do anything is if you #1 ran linux server and #2 had a program that did shell execution for some god unknown reason

if you put something on the internet, there are a bunch of places which will just run malicious requests for various buggy frameworks

its probably an endpoint in some php framework that is meant to be private, but easy to misconfigure

Configuring Flask-SQLAlchemy to use multiple databases with Flask-R...

I have a Flask app that uses Flask-SQLAlchemy and I'm trying to configure it to use multiple databases with the Flask-Restless package.

According to the docs, configuring your models to use multiple

whats manager?

#

i'm not using restless

#

and it doesn't actually show the import

so...

sry idk either

but mby this helps

from a yt vid i found about multiple databases in flask with SQL-Alchemy

tacit brook

I know how to do that. I just can't figure it out spread out over blueprints

ah

I think I can load it in the main.py file then store the db in config and access with

but I think websockets would be more reliable in this case.

wind walrus

Somebody said I’d need to combine web sockets and token, but is that so?

open tinsel
wind walrus
#

The “model” you speak of is like a flask SQLAlchemy database right? db .column

tacit brook
#

me?

native tide
tacit brook
#

everything on the page is going to be there lmao

#

its the page source code

open tinsel
#

Yes, it's the source code but not the chart data

tacit brook
#

... if the chart is one the page its going to be in the source code. well actually I guess they could do some weird iframe thing but then I don't think it would be saved anyway

wind walrus
tacit brook
#

I can try to get it later. RN its too much of a pita to switch venvs

wind walrus
#

This is the pseudocode they gave me

#

How would this work? I didn’t understand his explanation :/

#

He said that I could do it that way - using a column in the model - but that I could do it using only tokens

native tide
#

you give the user who edits a token for example 1 hour if he doenst refreshes he gets kicked and someone else can edit and if someone already edits then the doc is not editable so the requesting user doesnt get a token to edit. Its basically checking who got a token to edit and who not and when the doc is editable and when not

open tinsel
wind walrus
#

And this wouldn’t involve web sockets at all?

#

Oh needs sockets?

#

Lol some ppl are saying I need sockets others are saying I don’t idk

opaque rivet
opaque rivet
open tinsel
#

Do you have an example?

wind walrus
#

Yeah I understood that

native tide
#

not rlly it just takes an api and some javascript who makes request to see who has a token and who not and which file is editable and which isnt

wind walrus
#

Ummm so omega you are saying that web sockets are not necessary?

opaque rivet
wind walrus
#

I want to make sure that the tab isn’t duplicated anywhere - different tab on same browser, different browser, different device, etc...

opaque rivet
wind walrus
#

I mean a rea time collaboration system like google docs is ideal but I think that’s too hard

native tide
wind walrus
#

Ah okay, thank you for the conclusion, I now understand why web sockets is better than just tokens

#

I’ll try to implement it

wind walrus
native tide
opaque rivet
wind walrus
#

So I combine web sockets with the data “editable” thing with tokens

wind walrus
wind walrus
#

Wait the token to force the user out if they have been editing for like 2 hours, is that python or JavaScript?

native tide
#

I dont know flask but in django which is similiar i would do it in pyhton but its probably also in javascript possible

opaque rivet
# wind walrus this

Oh I see, I don't really see the point of tokens here - use tokens just for the authentication of users. It would go something like this:

  • User requests websocket connection to server

Conditionals:

  • You check if they can edit the document (I assume you have a Document model with a relationship to its users who can edit it)

  • You check if the document is editable (e.g. from a boolean field in the Document model) (editable=True) turns to (editable=False)

  • If so, accept websocket connection and continue.

  • Else, deny the websocket connection.

If the user times out, closes the window, stops editing etc, you'll have a function closing the websocket and then turning editable back to true.

Also after an arbitrary amount of time you can disconnect the websocket connection (threading will be needed here) but you'll need to inform the user on the frontend that it was disconnected (so python + JS)

#

and if you're learning JS, getting into a framework would make stuff like this easier and more manageable. e.g. with React you could've avoided websockets all together (that's not a bad/good thing) - websockets are great to know

wind walrus
#

Wow, thank you for such a detailed walkthrough

#

I’ll definitely give it a try when school ends

#

Yeah, I do indeed have a Document model

#

“If the user times out, closes the window, stops editing, etc”

Does python check this? Or JavaScript? Cos timing out is python, but closing the window is JavaScript right?

opaque rivet
wind walrus
#

Ah

#

So just check if web socket connection is broken

opaque rivet
#

you'll have a function which is fired when your websocket disconnects (in python) which will do your cleanups, like settings editable to true

wind walrus
#

Okay, understood, thank you very much

opaque rivet
#

at least from my experience with django & websockets, I doubt flask would be much different conceptually

open tinsel
#

hey, I got clobbered looking at my scraping

#

and missing data

tacit brook
#

is their anything bad that can be obtained from a database object class?

#

a db.Model

#

I'm making an API that returns values from it

# 
def getFields(msg, fields):
    #ex: ?fields="author_id,content,created_at"
    fields = fields.strip('"')
    fields = fields.split(',')
    

    allowed_fields = ['']
    
    res = []
    for field in fields:
        field=field.strip()
        if field in []
        field = getattr(msg, field)
#

and wondering if I should have an allowed_fields check

#

is their any private data in a db.Model object assuming that the data stored in the database isn't private?

#

I.E. login info

# 
query = current_app.config["DiscordDB"].query.order_by(desc('message_id')).filter_by(author_id=author_id).limit(10)
    
    result = []
    for msg in query:
        result.append(getFields(msg, fields))
#

eh I will just add it. The overhead from a check will be fairly trivial

#

heh if I cared I guess I wouldn't be using python

#

save a try,except block anyway

#

... how tf do you return a json list?

#

x = [1,2,3]

#

return jsonify(x) doesn't work

#

return jsonify({x}) doesn't work

astral dove
#

Why doesn't it work?

tacit brook
#

lemme re run

#

not serializable I think

astral dove
#

And is x definitely just a list of integers?

tacit brook
#

I know i can do return {"data":x} but I don't wanna

#

no its a lit of a lot of stuff

#

*list

#

integers and strings

astral dove

There must be another data type in there that doesn't map to JSON

its a little hard since vs code won't let me set breakpoints in the blueprint files

where q is a query string

its all js

open tinsel

so, why can't I scrape it?

tacit brook
#

because its not being sent to you as a html webpage

#

but as a js application

#

your browser turns that into html

open tinsel
#

so that explains why I can get it from the saved file

tacit brook
#

yea

#

you could use selenium

open tinsel
#

ok, I'll look at selenium

tacit brook
#

or you could scrape the js

open tinsel
#

how to scrape the js

tacit brook
#

nvm you cant

#

its not there at all its fetched from server

#

yea selenium your only option i know of

#

lemme see if I can get the request browser makes

open tinsel
#

hey thanks mate. Everyone else just says it's easy, just do this.

#

I'll learn selenium

tacit brook
#

Yea no dice I think on browser requests. It does send a lot of data as a response to a cuple requests but I can't find the values in there

open tinsel
#

Anything particular I should look for in a selenium tute?

tacit brook
#

sorry idk a ton about selenium as far as this goes

#

I kinda just know how to click buttons and enter text lol

open tinsel
#

no worries. really appreciated

tacit brook
#

do you strictly need THAT data?

#

I don't really get how the y-axis labels are that useful

#

because theirs a good chance you can get the same data from other sites

#

which may be more scraping friendly

open tinsel
#

Yes y-axis, it's essential to use regression to reconstruct the data from sgv Link to full app above code

tacit brook
#

ah

#

yea I don't think their in the request

#

the points on the graph are but their also not great for scraping

#

the points are all numbered and it kinda looks like its delibritly made hard to fetch

open tinsel
#

no, I take the svg shape line and use the y-axis to recreate the data to the cent

#

using chart coordinates

tacit brook
#

ah neat

open tinsel
#

some joker told me I couldn't do it without a heap of js bs

#

lol

tacit brook
#

they may have been right lol

open tinsel
#

if you run my app you get the data to the cent

tacit brook
#

this seems like the worst possible way to get that data lol

open tinsel
#

I agree

tacit brook
#

but sounds like a fun challenge

open tinsel

maybe it is time I learned js

It's more about the journey

What's your project?

if you can't remember what you are looking for

#

oh yea lol

open tinsel

some good scraping would be handy

what are you going to do with your code?

tacit brook
#

idk

#

nothing if I cant get my damn query to work

open tinsel
#

have a good day

tacit brook
#

you too

how would I do this

# 
  query = current_app.config["DiscordDB"].query.order_by(desc('message_id')).filter_by(author_id=author_id).filter_by(content=f"&{q}&").limit(size)```
#

everything works except the content

#

oh... I put & instead of %

#

lol I don't think it works anyway but let me see

#

yea it doesnt

#

you can do
User.query.filter(User.email.endswith('@example.com'))

#

but I have the database object stored in the app.config

solved it needed filter not filter_by

oh, so a framework just manages the functionality of things like buttons that do stuff?

no buttons are frontend thats in your html/js file. frameworks are specialised for a use e.g web development and then they manage some things like how to add 3rd party packages,how to set up urls and so on

if thats wrong sry but i dont know flask rlly i just googled it up

native tide
# dusty moon oh, ok.

i would suggest to watch some yt tutorials of making a django site and then u understand it better. I learned it that way myself too
For example DennisIvy,CoreySchafer, justdjango
But u gotta watch out bc of the syntax. the tutorials are kinda old and it changed a bit

dusty moon

should i learn html first or not? for me, html is easy. my problem is understanding how all the web stuff works

native tide
#

i learned it before but i dont think its rlly necessary bc u learn a lot of html with django or flask as well

dusty moon

i mean, i wanna learn clean html/css but, if its not the correct way of learning web stuff then what should i start with?

Hi everyone
How do you create a filter for a DRF serializer field?
For example I want my serializer to serializer only those objects that have name = "Product" from the queryset

native tide
#

u can learn it but i learned it myself before django too and now i just use some prebuild design and change it a little bit or use bootstrap or a css framework which provide css style which you simple appy in html

dusty moon
#

oh, i actually wanna make my own designs. im really good with gui design and stuff.

native tide
lime lava
#

So the queryset isnt actually a queryset

native tide
dusty moon
#

i am

lime lava
#

So I cannot apply SQL type filters

#

directly

dusty moon
#

btw, in a kind unrelated (but a bit related) note, can i use html/css in normal gui libraries in python? like tkinter and pyqt.

native tide
# dusty moon i am

great for ya but mby try bootstrap for the start or after some time when u focus on backend stuff bc it provides a lot with no css basically and simple html classes to apply

native tide
dusty moon
#

i heard that with some "computer magic" you can use some css. but i heard its possible in pyqt, idk about tkinter

dusty moon
native tide
lime lava
#

Yes true, but their model does not inherit from Django Models

#

Or else I would have directly used ModelSerializer

lime lava

Very purpose specific

dusty moon
#

lol seems like the dude in the comments got downvotes, i didnt look at that... so maybe tkinter dont have a workaround

native tide
# lime lava quartic_sdk

ok but u can still filter it just without the models filter. there are other filter possibilities e.g with Q or django-filters

native tide
dusty moon
#

im tryna learn pyqt anyway so idc lmao

lime lava
#

@native tide I just want to know if we can do something like this

#

(value)

#

Here value='product' is only for explanation

#

It will give an error

native tide
#

yeah u have to make the queryset in the views.py and pass it as the queryset with the get_queryset method

#

thats the only way i can now think of it

lime lava
#

Yes that is possible

#

Just found out that seriailzers cannot filter anything

native tide
lime lava
#

Yes, will try this

I'm using Django. When creating an new instance of model A, how can I get the some value from an instance of FK1 linked to the current logged in user and assign them to the newly created instance of model A ?

native tide
#

if you want to do it as soon as the instance is created i would suggest signals. thats like 2 lines of code with it

opal portal
native tide
#

basically some code thats runs before a instance saves/deletes or after it.
for example: ```
from django.db.models.signals import post_save
@receiver(post_save, sender=User)
def create_profile(sender, instance, created, **kwargs):
if created:
Profile.objects.create(user=instance)
Contact.objects.create(user=instance)

#

and just replace it with your models and you should be good to go

opal portal
#

what method should i override in the modelviewset then ?

native tide
#

not in the modelviewset in a seperate file called signals.py

i think i just have found it. My javasrcipt is so rusty hehe thanks anyway !

native tide

Ok 👌

versed python
#

I have

struct A {
  attr: i32
}
struct B {
  attr_other: i32
}
let a = A { attr: 12 };
let b = B { attr_other: 12 };

Now, I know that a.attr == b.attr_other will yield true. However, I want that a == b should yield true. In python, I would override the __eq__ method on the class to achieve this. How would I do this in Rust?

alert("Could not send data to Django. Error: " + xhr.status + ": " + xhr.responseText);
}
});
});
but my "info" is filled at the start (after var info with an alert i get my info objects) ) but the ajax request does not seem to pass it with the POST any help ?

hi i have question

#

so something is writen in a console (log)

#

and

#

i want it to be in a variable

#

variable = the console log

#

how can i do it

native tide
slim maple
#

you know when you inspect

#

you have the elements

#

and console

#

this console

unknown.png
native tide
#

thats the developer browser console and you want to get the value a user writes inside of it and save it, right?

slim maple
#

now

#

no*

#

just

#

what is writen in there

#

to be in a variable

native tide
#

so no user input? just the error message or the console.log u did in your js file?

slim maple
#

no

#

just console.log

#

it needs to get into a python variable

native tide
#

ok but why dont you try to render the text you would console.log in a p tag with the name = "console.log" and then query it within the django views and save it in a variable?

slim maple
native tide
#

so you are web scraping?

slim maple
#

i was looking for tutorials on youtube

#

but you had to get the id

but console log doesn't have an id

I'm working with flask and getting this error on all my pages:

The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.```

I think it may have to do with the below line in my routes.py file:

app = Flask(__name__)

Because when I comment it out, my pages render but they don't get the packages from __init__.py

Any help would be great

        x = int(float(request.form["x"]))
        y = int(float(request.form["y"]))

        location = "images/" + file.filename

        with open(location, "wb") as target:
            file.save(target)

        resistance = Detector.create().detect(location, x, y)

        bands = resistance.bands

        return render_template("Resistor.html", data=bands)

    return render_template("Resistor.html", data=data)


if __name__ == "__main__":
    WebServer.run()```
#

dont mind the comment its just a reference for my write up lol

stable hemlock
#

Your problem is that the render template inside the if only renders when there is a post request. As soon as there is a get request the other template will render.

ahhh i see

what would be the best way to go about this

sorry im not the best at this...

Hey how to scrape a javascript based site

or a site which loads data after taking some seconds

#models.py
class A(models.Model):
    ...
    fk1 = models.ForeginKey(FK1, on_delete=models.CASCADE)
    fk2 = models,ForeignKey(FK2, on_delete=models.CASCADE)
    ...

class User(AbstractBaseUser):
    ...
    fk1 = models.ForeignKey(FK1, on_delete=models.CASCADE)

opal portal
#

couldnt figure out how to do so, signals seem like an overkill

native tide
#

u need 2 to 3 lines and got what you want

opal portal
#

i tried

@receiver(post_save, Sender=A)
def save_A(sender, instace, created, **kwargs):
  if created:
  A.fk1 =
  ...
#

but i dont know how to access the current logged in user within this signals.py

versed python
#

You're probably doing something wrong if you need to access the user in a signal

opal portal
#

i guess directly access from the view with request.user.fk1.fk2 is better ?

native tide
opal portal
native tide
#

just replace the user with the model u want there.it was an example.

opal portal
#

what i want is when a logged in user create the A, i can get some of this user's value to assign to the new instance A

#

i changed sender to A already but couldnt figure out how to retrieve value from current logged in user or its linked model

native tide
#

mby I'm miss understanding you

opal portal
#

im sorry my bad for stating the problem. contribution is the A in my actual code

#

@receiver(post_save, Sender=A)
def save_A(sender, instace, created, **kwargs):
if created:
A.fk1 =
...

#

i did this but i need to assign a.fk1 = user.fk1

native tide
#

ok i get it now. You want it way easier than I thought

#

u can make that in your views.py like you said by

  A.fk1 = request.user.fk1

bc request.user is always the logged in user or (null or false not sure) if hes not

opal portal
#

yeah thank you

#

also when i have a Profile model linked to user, is it better to use onetoonefield or foreignkey with unique=true ?

native tide
#

sry for getting you on a wrong path but i thought u know the request.user thing

opal portal
#

but it look kinda clumpsy to do request.user.fk1.fk2

#

i know but i thought there is an elegant way to do so xD

native tide
#

I even think that there are almost they same. OneToOneField and Foreignkey with unique=True

opal portal
#

is there any difference if i put the onetoonefield in User model and in Profile model ?

#

beside the backward relation

native tide
#

no but I think for a profile model its good to have a backwards relation

quasi inlet
#

i guess this is web development, i have an html string from an website for example youtube.com and want all image objects or better the src url of those image objects, how to filter those?

#

i can get the html code in string format from a website with requests from python, this is what i already have. i wanna know how to filter all image urls and output them / store them in a database
