I need some help with django.
Basically, I want to create a form with one field.
The field of that form is going to be some valid ID of a page, for example: /customer/7/, if the user enters 7, it will post a message in that page (/customer/7/), the issue is, I'm not quite sure how to do it, would anyone mind to give a hand?
lethal orbit
Why would the user enter an ID manually? Normally, you get the ID from the URL. If you want to display a form already at that URL (/customer/7/), you can get the ID from the route, and pass it in the form using <input type="hidden" name="customerId" value="7"> (or in your template, <input type="hidden" name="customerId" value="{{ customer_id }}"> or similar).

How can I do an if statement to see if an object already exists without getting a Application matching query does not exist? ```python
if Application.objects.get(owner=request.user) is not None:
basically I am trying to make sure the user can only submit once
lethal orbit
.get raises an error if it doesn't exist, so you need to try/except it.
wise cipher
ahh that makes sense, thanks patryk!
lethal orbit
try:
app = Application.objects.get(owner=request.user)
# app returned exactly one object, so work with it
except DoesNotExist:
# app doesn't exist. You can create it or something
Though I am not a fan of doing things that can raise exceptions in an except clause...
Not sure what you are doing exactly, but probably better to do something like:
does_not_exist = False
try:
app = Application.objects.get(owner=request.user)
# app returned exactly one object, so work with it
return
except DoesNotExist:
# app doesn't exist. You can create it or something
does_not_exist = True
if does_not_exist:
try:
# more stuff
what is the downside of using the 1st method?
lethal orbit
You can also nest:
try:
...
except DoesNotExist:
try:
...
except OtherError:
...
Can you recommend some front-end videos
lethal orbit
what is the downside of using the 1st method?
Don't do something like:
try:
app = Application.objects.get(owner=request.user)
# app returned exactly one object, so work with it
except DoesNotExist:
# app doesn't exist. You can create it or something
app = Application.objects.create(...)
Because then you can get unhandled exceptions.

I mean if you can legitimately watch a 3 hour video and take in everything and put it into practice immediately with No need for practicing or looking up anyway then you're probably the first person in the world todo that
you're gonna spend well over 10 hours messing around even after watching the videos lol

No one says you have to watch all 3 hours in a row... Just learn, practice, and keep watching.
You can easily spread it over a week, and you can watch sections multiple times.
If you're not learning from the video, then look for another source ๐
earnest trail
Does anyone know of a Python library / framework that can do similar things as huginn (which is written in ruby)? Hereโs a link to the huginn repo if you are not familiar with them: https://github.com/huginn/huginn
I really love the system but as I donโt write ruby, it makes it hard for me to extend / debug it. What huginn is: a system that allows you to create โagentsโ and listen to events and then do something with them. Kindda like rolling your own IFTTT but self hosted.
I have looked into commercial services e.g. Zapier but they quickly became expensive when I am having too many events. Then I looked into writing my own but I feel that something like this must exist already and donโt want to repeat the effort, and at least it would be easier if I could simply write the custom parts on top of it.
Any help would be appreciated. Please tag me if you reply (or tell me if this doesnโt belong on this channel). Thanks!

fast basin
for large django projects templates folder should be separate for each app?
sly canyon
@fast basin I don't use Django, but I'd certainly recommend you to do so.
If some template is used by more than one app you can leave them in the templates folder root or just put it where it mainly belongs and access it on the other app by constructing the path to it. If your project is growing fast, sooner or later you'll have so many templates in one dir that it'll be hard to maintain and find the one you're trying to access
native tide
Is there an easy way to send form data to a specific page (by using the field the user has entered, for example, the user enters 123, the form data will be sent to /users/123)?
(Django)
sly canyon
the templates folders of the app I'm mainly working in looks like this, helps me a lot to keep track of my changes
@native tide which framework are you using?
native tide
Django
fast basin
the templates folders of the app I'm mainly working in looks like this, helps me a lot to keep track of my changes
@sly canyon
you got it nicely maintained I'll follow the same approach.
sly canyon
I'm not sure how to handle that in Django, but most likely you'd just need to set the action atrribute in your form tag, specifying the URL that will receive that POST request
Maybe something like
<form action="/users" method="post" novalidate>
You'd still have to work on your /users POST handler to capture the form data and redirect the user somewhere, displaying something.
surreal thicket
in django i think you need to associate the URL with a View that renders the Form in urls.py
i'm not 100% how it works though
there is a lot of indirection w/ views in django @sly canyon
the <form> itself is generated by an instance of a sublcass of django's Form base class
you just slot a placeholder for said generated form into an html template
sly canyon
Might be similar to Flask-WTF's FlaskForm
But you'd still have to render that using Jinja2 right? The template might be the key to accomplish what he wants
sly canyon
Yup, very similar to Flask
templates/_formhelpers.html
{% macro render_field(field) %}
<div class="{{ field.name }}-wrapper">
{% if field.type == "BooleanField" %}
{{ field(**kwargs)|safe }}
{{ field.label }}
{% else %}
{{ field.label }}
{{ field(**kwargs)|safe }}
{% endif %}
</div>
{% if field.errors %}
<ul class=errors>
{% for error in field.errors %}
<li>{{ error }}</li>
{% endfor %}
</ul>
{% endif %}
{% endmacro %}
templates/some_blueprint/my_form.html
{% from "_formhelpers.html" import render_field %}
<form method="POST" action="" novalidate>
{{ form.hidden_tag() }}
<!-- Name -->
{{ render_field(form.name) }}
<!-- Email -->
{{ render_field(form.email) }}
<!-- Phone -->
{{ render_field(form.phone) }}
{{ form.submit }}
</form>
(Kind-of custom made, 'cause there are easier ways to render fields)
surreal thicket
at which point then yes, you need /users/<int:user_id> in your URL spec, which handles the form data with some kind of View
yeah the flask community sure has done a great job of emulating all the batteries that django includes ๐
(nb: i prefer the modularity of flask)
sly canyon
I feel like flask is more customizable (not that I have ever tried Django), it also seems like it only includes things as we need them to be included (that's the lightweight aspect of it)
fast basin
@sly canyon In an image compression django web app. The user will upload an image that will be stored in my DB first? or I have to use the image compression algorithm before inserting inserting the image to DB then return that image to user as a compressed image?
acoustic oyster
I feel like flask is more customizable (not that I have ever tried Django), it also seems like it only includes things as we need them to be included (that's the lightweight aspect of it)
I have found django fairly resistant to customization. While the options are there, django becomes much more difficult when you start going against the assumptions django makes about how it should be used. I have not used flask, haha, but I assume this to be true
In an image compression django web app. The user will upload an image that will be stored in my DB first? or I have to use the image compression algorithm before inserting inserting the image to DB then return that image to user as a compressed image?
I would save the image url to a DB, then save the image to a local file, then perform compression, then send the image back if it needs to be.
fast basin
@acoustic oyster You mean saving the image like the static files? for short perioed of time
acoustic oyster
yes
sly canyon
@fast basin again, I have no knowledge of how Django works whatsoever. But if I was in your shoes, I'd store the images in an temporary user_uploads folder, compress it, validate it, then I'd store it in the DB.
acoustic oyster
in django I save images to "media"
as per standard
very similar to how static works
native tide
I used a postgres database and saved it directly to the database
acoustic oyster
you could then delete it if you needed to
I used a postgres database and saved it directly to the database
while this certainly works fine, it is not optimal for performance
--to have a DB serving images directly
native tide
No, sending a file would be better
But managing the files can be difficult
And I have never attempted to save binary data to a database before so I went this route
fast basin
well thanks as more of you guys suggesting to store it in server disk rather then DB. I will go with this approach
native tide
I would recommend using an integer identifier used as primary key in your database
Or any other value you use as primary key
prisma jackal
What does <span> do?
acoustic oyster
it creates an inline text element
sly canyon
https://docs.python.org/3/library/imghdr.html might help you to validate img data
native tide
As fileName could overlap and instead of modifying the file name, saving it using the key as name and then keeping the original name in the table in the database
acoustic oyster
it is like <p> but the default style is inline, iirc
sly canyon
https://github.com/GoogleChromeLabs/squoosh might help you compressing img data
not sure if Squoosh is supported as a back-end solution
native tide
Also, unless someone uploads a uncompressed image, itโs probably already gonna be as compressed as can get unless you change the format
fast basin
Or any other value you use as primary key
@native tide could be useful. if i store them in db.
prisma jackal
it creates an inline text element
@acoustic oyster that is true, but I don't know how it works and when to use it.
native tide
Are you going to use a database to maintain image meta data?
Like ownership, upload time, etc
fast basin
https://github.com/GoogleChromeLabs/squoosh might help you compressing img data
@sly canyon I was thinking of implenting the algorithm on my own but if there's a library why not to use that ๐
native tide
and prevent overwriting existing images who share same file format and name
acoustic oyster
@prisma jackal you would use it wherever you need inline text.
This means it mostly ends up being used for small areas of text, perhaps embedded in a block tag. i.e if you want some different style for some part of a paragraph, you could do something like
<p>words go here, but <span style="color: red;">this</span> is special</p>
Thx
fast basin
Are you going to use a database to maintain image meta data?
@native tide No anyone can upload as guest.
sly canyon
@fast basin now that I'm thinking it straight I don't think Squoosh will help you to automate that task, but PIL along with numpy might do the trick for you, maybe scikit-image or something. You can also rely on third-party APIs to POST the image and get them resized/compressed.

i want to hide icon from 992px to 768px
BUT after 767px i want to unhide icon
acoustic oyster
you should just make multiple queries then.
like:
min-width 768px{display: none;}
min-width 992{display: block}
something like that, but that actually is code and does what you want, haha
and it would be visible in the base css (without media query)

@royal radish there's a flask-sendgrid module. But ofc, it is for send grid. Flask-user has mail capabilities as well. Also, you could just use python's inbuilt email package i guess. You don't really need something flask specific

We are building a DB/model for API routing to React frontend, the person working on the front end asked for information to be keyed as follows, as an example:
"ttop": {"full": 'Text Topical', "description": 'description text'}
but I'm not sure how to accomplish that in models, the "ttop" field is also a model, there will be others e.g atop, tbat, abat, free etc as shorthands for "text battle", "audio topical" etc, and that is what this dictionary is intended to define -
I currently have
battle_short = models.CharField(max_length=5)
battle_full = models.CharField(max_length=50)
description = models.CharField(max_length=500)
@strange briar oh yeah, that's cause you have to change the UserChangeForm cause you changed to custom user. Look at the
accounts/admin.pyin the repo i sent, and use that. It should work.
@versed python Hi again Ignis and sorry to disturb you, I followed your instruction and could implement the hash on my passwords so thank you ๐ however, this code is quite blurred for me, if you have a bit of time, can you explain it to me ? there are several files i had to implement like forms.py, modify admin.py..
versed python
yeah sure, dm me with what you need @strange briar

Hello, I got issue deploying a django app on wsgi server. When i run django app with runserver 8080 it works as expected, but when i tried to host django on cherryPy server, i got issue with django that he can not find module name settings. I looked up on stackoverflow but, the solutions over there did not work correctly. I can post some pictures of my project structure.
versed python
@hidden trout runserver is not supposed to be used in the actual production server, instead you need to use wsgi.py
hidden trout
@versed python i know that, this server is only used for testing purposes or debuging. I tried to deploy my app on cherryPy server, with wsgi.py. But when i tried to start django on cherryPy i got this error ModuleNotFoundError: No module named 'mysite.settings'.
dapper tusk
you need to manually need to insert the package into path
hidden trout
@dapper tusk you mean with sys ?
dapper tusk
ye, sys,path
versed python
you need to manually need to insert to package into path
@dapper tusk are you sure? I never had to do that
versed python
doesn't django do that itself?
dapper tusk
no
import os
from django.core.wsgi import get_wsgi_application
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'politika.settings')
application = get_wsgi_application()
```is all the default wsgi.py doesdepending on how your wsgi server works, it can sometimes not be needed
versed python
yep and assuming the project root has an init.py, it should get inserted into path automatically
dapper tusk
but sometimes you have to modify sys.path
no
the containing folder does not become a package
unless you do -m folder.file
hidden trout
i got the same, but before setdefault , I tried to append path to settings module. I will send you my project structure if thats okey?
dapper tusk
I suggest inserting at 0, and use the path containing the mysite directory
versed python
the containing folder does not become a package
@dapper tusk is this a shortcoming of python or the server in question then?
dapper tusk
it is just not how python works
hidden trout
I'm so confused about this...
dapper tusk
if you have a.py and b.py in mydir, then the import is import b, not import mydir.b if you run python a.py
if you instead do python -m mydir.a, then you would do import mydir.b
personally, I dislike this system

Can't wrap my head around this. Lets say I have this project structure

Hello guys, using Django how would you add validation constraints to a modelform?
For a first name, will you use widgets = { 'first_name': forms.TextInput(attrs = {'placeholder': 'Alicia','minlength':2,'maxlength':30} for example or is there a better/other way to do it?
versed python
@umbral echo it's much easier to use validators
first_name = forms.CharField(validators=[first_name_validator], widget=forms.TextInput())
something like this
look into the django docs, they explain this is detail
umbral echo
Ok thanks a bunch! I tried to make one, one day, such a fail ! I'll try again today, because I always block on this

@little furnace did you find it?

You gotta have an static folder in your project then put the css file in it.

How can i do that

like that?
hidden trout
Do you think that i got issues with path because of the naming of my project. If you look closely I got ResourceManager as project, then in the same directory I have Resource manager... which was created with django admin. @dapper tusk
dapper tusk
it makes it somewhat annoying to debug, but I have gotten similar structures to work

Yeah thats right

I'm really out of ideas, what should I do next. Do you have some pointers to what had gone wrong? @dapper tusk

Hey guys I am using Flask as a back end for my project on the front end I am using Javascript to send the following request
fetch('http://127.0.0.1:5000/updatetask', {
method: 'POST',
mode: 'no-cors',
headers: {
'Content-Type': 'application/json',

body: JSON.stringify({
'TEST': 'test',

and on the backend I am accepting the request with
@app.route('/updatetask', methods=['POST'])
def update_task():
if request.method == 'POST':
print(request.json)
print(request.form)
return 'Testing'
and for some reason neither json or form gets any data

no point having that check because flask will return METHOD NOT ALLOWED if its not already a POST request

Reposting because I still need help :/
@native tide You will probably need to override__init__method for your form class to make dynamic forms (that what you need right?)
native tide
I'll give you a better example, say there's a form page, there's a field called 'ID' or something, now, I want to display the form data only on that specific page ID (user/ID/ or user/5/), and if I go to another URL (user/9/), it won't show that form data on that page.
versed python
oh that's pretty easy, you don't need to mess with forms for that.
look into setting permissions on a per-view basis @native tide

Why isn't "ID" being generated for new entries in a model?
from the MongoDB, it is recording them with ObjectID, it is breaking the Django
_id
:
5f565ebd9351425d2c8a516d
battle_short
:
"ttop"
battle_full
:
"Text Topical"
description
:
"Text Topical Battle, an epic clash of literary might"
then gives the following error:
rather, when I try to access the data from admin panel it says "Battle type with ID โNoneโ doesnโt exist. Perhaps it was deleted?"
from json:
[
{
"id": null,
"battle_short": "ttop",
"battle_full": "Text Topical",
"description": "Text Topical Battle, an epic clash of literary might"
},
id there is read as null

@maiden kraken set thetemplate_nameattribute inside your view. Or you can override theget template_namemethod if you want more fine-grained control.
maiden kraken
@versed python
I have it like this, I think this is what you are talking about
path('login/', auth_views.LoginView.as_view(), name='login'),
path('logout/', auth_views.LogoutView.as_view(), name='logout'),
but with like this I have keep my templates in registration folder
versed python
path('login/', auth_views.LoginView.as_view(template_name='your_filder/login.html'), name='login'),

I suggest you actually Subclass the django login view and then use it though. This will enable you to extend that view in future easily @maiden kraken

I am not really sure if it is within my reach for now

# accounts/urls.py

Flask-WTF question.
I have this script in in the conversion.html:
<head>
<!-- [...] -->
<script async src="https://www.googletagmanager.com/gtag/js?id={{ gtag_id }}"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
gtag('config', '{{ gtag_id }}'), {
'send_page_view': false
};
gtag('event', 'generate_lead');
</script>
<!-- [...] -->
</head>
But I don't think Google would track the source of that conversion as the "conversion" page serves several different products and their generate_lead event doesn't support any parameters that references the source of the event.
So, I want to trigger that script only after the form validation as such:
@bp.route('/some-route', methods=['GET','POST'])
def some_route():
# [...]
form = ConversionForm()
if form.validate_on_submit():
# Here it should trigget that JS script
# [...]
return redirect(url_for("conversion"))
return render_template('some_route.html', form=form)
@bp.route('/thank-you')
def conversion():
# [...]
return render_template('conversion.html')
Is that even possible?

Is Django good tool to make discussion forum or is it usually made in PHPbb (this is what i remember was used long time ago)?

My question: does anyone have a good resource on implementing external authorization with Django. I have a no-fun setup of CAS for authn and authz based on LDAP attributes I'm porting from another application.
frozen spear
so i;ve searched online but no topics on that
i wanna make a function that when a submit button is pressed its checks a form's input
and if its contains a word from a tuple (bad_words tuple) its gonna reload the page or pop up a message
acoustic oyster
One sec, lemme switch to pc
I believe you can do something like this:
class MyForm(forms.ModelForm):
model = User
fields = ["username"]
if request.method == "POST":
if form.is_valid():
for content in form.cleaned_data.values():
content = content.split()
if any(True for x in content if x in bad_words):
return render(request, the view)
else:
form.save()
dont you dare answer this now! this took time!
haha
lethal orbit
and if its contains a word from a tuple (bad_words tuple) its gonna reload the page or pop up a message
No!
Bad!
frozen spear
NOOOOO
frozen spear
ok brb lemme try linuxpro suggestion
lethal orbit
x in set is much quicker than x in list|tuple as those need a sequential scan.
acoustic oyster
this is somewhat pseudo code. But I think this does what you want.
I would personally add this check to the "is_valid" method of the form itself to make things easy
frozen spear
how so
acoustic oyster
I should probably have tested this solution, but I just woke up and dont feel like messing with django xD
acoustic oyster
hooray
frozen spear
so its a win win
lethal orbit
If you have 10,000 words to check in a 10,000 word tuple, it's 100,000,000 operations. 10,000 words in a set of 10,000 words takes around 10,000 operations.

hey, not sure where else to ask this, but this channel seems to be the best match since I'll be using the following for web design mostly:
im making an http server from scratch with sockets and i got the basics down and am able to render html files in the browser through the server but i want to take it to the next level and make some sort of browser sync system, when a file changes in the working directory, make the browser refresh automatically. im not looking for a full on tutorial just some pointers so i know in which direction to take this.
Any help is much appreciated!!
acoustic oyster
also: I did not know about that, this will change how I program forever
Well, if you are using websockets, then you can use JS for the front end and then your browser does not need to refresh
twin tapir
hm ok thats one option
acoustic oyster
wait, do you mean like a development server where when you change the backend/python it automatically refreshes?
If you just need the front end to be a live stream of data from the DB/API/data on the backend, then I think websockets with JS on the front end is the way to go.
yes, good. Because my code was from memory and I was not sure if it would work haha
frozen spear
lets try now
acoustic oyster
test it out and let me know what errors you get xD
oh, you know what, I got fancy with the generator, but this would actually be more efficient as a loop where you break/return if a match is found. Since there is no need to check the rest of content if a bad word is already found. This should work fine though
acoustic oyster
oh, you need to return your redirect at the end of the view (if they are successful)
frozen spear
did that
acoustic oyster
lie return redirect()
acoustic oyster
but that also means that the form was valid in that test
frozen spear
when i went to signup
its popped up that
is possible to do the opposite
so like
if form is valid its done
else its detects a bad word its redirect or pop up an error
acoustic oyster
show your code, it is basically saying your function is not returning anything
frozen spear
acoustic oyster
your form is not valid, you need a return at the bottom, for the case that the method is not "POST" which it will always be "GET" the first time you load the page
hallow jacinth
Does anyone have any idea how I use bootstrap class tags with flask? I tried just creating a div and adding the class, but that doesnt seem to work

if any(True for x in content if x in bad_words):
return render(request, the view)
else:
form.save()
return render(request, your_signup_form)
like this
haha, happy you worked it out xD
hallow jacinth
I used .className and not just className
acoustic oyster
in your code, you ONLY return anything if the method was "POST" which means a user pressed the button to make a "POST" request, but when you type a url in a browser, or click a navbar link or whatever, you will be making a "GET" request.
So in your code: the first load is NOT a "POST" request, so it ignores what is in your if statement and goes on to not return anything
frozen spear
@acoustic oyster btw what does 'request, the view' means like the function?
cuz like the code is in views
and im using uh UserCreationsForm
twin tapir
@acoustic oyster no all im doing is something like the http.server module but with my own preferences
acoustic oyster
sorry, that is supposed to be the same as return render(request, your_signup_form)
twin tapir
ill be using it for normal html/css/js

Do NOT use the inbuilt http server for production systems
frozen spear
heres the code

i dont really like viewing html files via file:// protocol haha
acoustic oyster
yeah, that looks good, this should not error immediately now xD
so we can see if my form magic works
frozen spear
hmmmmm the magic code is fine but the form got noobed
acoustic oyster
you need to pass the form in context with the same name you were using before
you need to pass the form in context with the same name you were using before
context = {'my_form": form}
return render(request, your_signup_form, context)
context = {'my_form": form}
return render(request, your_signup_form, context)
lel, you need to pass the form in both returns
the way you have it, it will load the form the first time, but if you submit it with a bad word, it will render the template without a form
frozen spear
acoustic oyster
define context right below your form, now context is not defined in the last return
acoustic oyster
lemme do some hardcore typing, uno momento
frozen spear

acoustic oyster
can you paste your code in instead of snippet?
frozen spear

def signup(request):
if request.method == "POST":

context = {"form": form}
bad_words = ("shit")
for content in form.cleaned_data.values():
content = content.split()
if any(True for x in content if x in bad_words):
return render(request, 'registration/signup.html', context)
else:
form.save()
return render(request, 'registration/signup.html', context)
it looks good, lemme just make some tweaks to your code.
from django.contrib import messages
def signup(request):
if request.method == "POST":
form = UserCreationForm(request.POST)
if form.is_valid():
bad_words = ("shit")
for content in form.cleaned_data.values():

form.save()
messages.success(request, "Account successfully created")
else:
form = UserCreationForm()
context = {"form": form}
return render(request, 'registration/signup.html', context)
I made the conditional a little more confusing, but this works better without doing any more confusing refactoring. I added a success message, so the user will be notified that their account was successfully created. I forget if you need to add something to the template for the message though

Instantiating a set also has a bit of overhead, so you can do that in settings.py once and import it in your script.
acoustic oyster
no problem
lethal orbit
For a small set, it's negligible though
(and for a really small set, a tuple can do the job too)
frozen spear
i will use google banned words which is hella big

haha

and load it in settings at startup.... then you save the with open("badwords.txt") overhead too

You can also read the file, instead of copy/pasting them in.

any recommendations for async server frameworks?
preferably something lightweight like flask

aiohttp
basically the lightest of them all
Starlette or Sanic are slightly heavier but will probably be more performant

@fair tide what framework are you using
fair tide
flask at the moment
fair tide
I was thinking I would render the page under an ID and then have a JS script grab data from another route to get some progress information
something like....
task_json = {}
# it'll be like {taskID:{'stage':"","percent":0}}
@flask_app.route('/generate/<id>`)
def generate(id):
# start background task to generate the thing, itll update task_json while its doing it
return render_template()
@flask_app.route('/info/<id>`)
def info(id):
return task_json[id]
and the javascript will get the json from the /info route and change the page accordingly

I am using sorl-thumbnail to generate thumbnails in django. what does this @@property decorator do?
I know it creates thumbnail when image exists, but I dont understand how generator works... why not normal function? does it works automatically when image exists?

I am using sorl-thumbnail to generate thumbnails in django. what does this @@property decorator do?
I know it creates thumbnail when image exists, but I dont understand how generator works... why not normal function? does it works automatically when image exists?
@maiden kraken@propertyis essentially agetter. It's a special type of function that allows you to doad.thumbnailas opposed toad.thumbnail()(which isn't a very good method name).
It checks that self has an image attribute that is not NoneType.
Honestly, I feel like this should be done differently... generate the thumbnail once instead of calling return get_thumbnail(), but maybe the get_thumbnail function caches those
If not, it should
maiden kraken
thanks for explanation. is property custom name or you can call it anyhow or are generators predefined? And do you know when the thumnail is created? Is it during object creation or is it during request for thumbnail?
lethal orbit
You'd have to look into the get_thumbnail method to know that...
maiden kraken
okay, get_thumbnail is a method from sorl_thumbnail I will not look that deep, that's not my level ๐
lethal orbit
Generators in python are a different thing... functions that return an iterable, in simple terms.
maiden kraken
okay thanks for help I will try to find more information about this topic on youtube

The property decorator is built-in. It's especially handy if you give a class an attribute, then decide to override it with a method down the line.
class Dog:
def __init__(self):
self.legs = 4
doggo = Dog()
print (doggo.legs) # prints 4
Then you decide to change the implementation....
class Dog:
def __init__(self):
self.amputee = False
@property
def legs(self):
if self.amputee:
return 3 # poor doggo
return 4
doggo = Dog()
print(doggo.legs) # still works as an attribute, even though it's a method

Just a quick question... Not sure if there's a better place to ask this but I want to write a Vue app using Python in the back-end, and I need websocket functionality in addition to my REST API. Originally I had thought I'd use the websocket module for the server, and Flask for the API, and just return a SPA with Flask, but now I'm seeing that Flask has the SocketIO package and that there's aiohttp web API functionality and I'm kind of torn between what I should use. Any idea on the best combination? I'd like to leverage async for the websocket portion of the app as I'm running subprocesses with asyncio and polling their system resource usage.

Yes, but you'd have to set the ALLOWED_HOSTS setting. https://docs.djangoproject.com/en/3.1/ref/settings/#allowed-hosts

@prisma jackal I never tried Django but I think you should do that validation in your back-end.
If you have aclass Voteassociated with aclass Userall you have to do is query if there are any Votes associated with a certain user, if it is, you would not allow them to access the cast vote page. Theuniqueattribute may help you, but I'm really not sure it will

What kind of things you can do with async in a web app?
sly canyon
@weary dragon you mean asyncio?
weary dragon
yes
sly canyon
Your just asynchronous requests as a general concept
sly canyon
Never used it, I use threads to make asynchronous requests, everytime I encouter a asyncio snippets of code I leave it understanding less then previously
weary dragon
yes, but i want to know what kind of stuff you can do with it
like, until now i didn't need to use it

do you guys get someone else to do the front-end ? I love working with Flask/Python, but when it comes to doing the front-end I give up. I do not like working with CSS at all
I have so many cool projects, yet don't finish them because of the front-end
sly canyon
@weary dragon Assume you have 500 users/minute on your web app and they have to fill a contact form. As soon as a post request occurs it will trigger send_email() to your contact@ajxshero.com mail.
I think that would be a good moment to implement async requests
but I don't know, my understanding of async is pretty much mixed with threads
weary dragon
thanks, i think it's a good exemple
sly canyon
I just feel like using threads whenever my app triggers something that is irrelevant to the user, but if that routine is not done, it would mess up the user experience
weary dragon
and that's a must know for a web dev?
sly canyon
another example I use threads...Whenever a User POST a Form demonstrating interest on a product, I send their data to a CRM platform and then show them a thank-you page.
If for some reason I don't use threads and the process of integrating with the CRM fails, the user will never see the thank-you page
So I just make the process of pushing that data to the CRM a thread and redirect the user to the thank you page.

Hi guys, after submitting a form w/ flask, how can I refresh the page?
versed python
@prisma jackal I'm assuming you're using django
prisma jackal
@versed python exactly
versed python
if you look at setting.py, there will be a dictionary, one of whose keys will be called template_dirs
it will have app Dirs in it
I am not sure about the names but I will try to explain what happens under the hood.
Basically when django is running on the server, it collects all the template folders (which can be configured via settings.py, i dont remember the setting name though) into a single folder from which it serves all your html files
for example you have two different apps called posts and registration and have two different html files in these under posts/templates/posts/home.html and registration/templates/registration/login.html. when django servers these html files it "collects" them into a virtual templates directory and which has a files structure like this
-- django-virtual-templates-directory/
-- posts/
- home.html
-- registration/
- login.html
So when you write something like return render(request, 'posts/home.html', context) then you get the correct html file that you requested for.
hope i was clear
@prisma jackal
prisma jackal
@versed python yeah, thx
versed python
here's the settings i was talking about

'django.template.context_processors.debug',
'django.template.context_processors.media',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
],
},
},
]
notice APP_DIRS: True. that does the trick
prisma jackal
@versed python so, the folder my_app\template (this should be named template) \base.htm?
versed python
if you write return render(request, 'my_app/base.html'),the django virtual template directory will be like this
django-virtual-template/
base.html
- posts/
- home.html
[..etc..]

and it should be named templates not template
