But what you said makes sense, a single string probably won't convert to JSON well..

I'm thinking it's an issue with post
rigid laurel
hmmmm - I don't know enough jquery to be of any help I think. The last thing I can think to suggest is $.post( "/", { name: "John", time: "2pm" }, dataType="json" );. My only other suggestion would be ditching jquery and using the default JS fetch API
const data = { username: 'example' };
fetch('https://example.com/profile', {
method: 'POST', // or 'PUT'
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify(data),
})
.then(response => response.json())
.then(data => {
console.log('Success:', data);
})
.catch((error) => {
console.error('Error:', error);
});
There's an example of posting some data with the fetch API
fossil bay
I'll give fetch a go! I've been trying this method for three days and can't for the life of me figure it out, haha. Thanks for the help, though!
rigid laurel
If you're having trouble with the fetch stuff. Ping me and I'll set up a minimum example to show the two parts working together

Hello, everybody,
I recently finished a book on "Flask Web Development", it was very enriching. So I was able to familiarize myself with Flask and SQLAlchemy to build a small REST API.
I would now like to do a more consistent project, so I turned to OpenAPI to do the specification of my future API. So I generated the backend code in Flask with Swagger Editor but I'm having difficulties to make the link with SQLAlchemy. The generated models should not be touched in case of code regeneration, which is logical, but how can I define my columns for my database? I was thinking of inheriting this model or maybe creating a model only for the database, but in this case I don't see the interest of this code generator.
I have difficulties to define an interesting workflow. Has anyone ever built an API from the code generated with Swagger Editor and implemented persistence with SQLAlchemy?
I hope my question isn't too general...Thanks for the help
fossil bay
I FIGURED IT OUT!
So the route needed to be '/extract'
$.post( "/extract", { name: "John", time: "2pm" }, dataType="json" );
Which makes a ton of sense lol
rigid laurel
oh - haha. It's always a simpler problem than it seems to be
fossil bay
Honestly. I'll tell you what though, never gonna make that mistake again haha

Hi, so I have the following function:
def get_user():
data = get_cookie_data()
if not data:
return None
else:
discord_id = data['discord_id']
print(discord_id)
current_user = User.get(int(discord_id))
print(current_user.username)
return current_user
get_cookie_data() is this:
def get_cookie_data():
try:
token = request.cookies.get('user')
return jwt.decode(token, read_file('./assets/public.pem'))
except Exception as e:
print(str(e))
return None
I am using Stripe with sessions api, which basically lets you pay and redirects you back to the main website along with a code. When I am trying to register the user to the database I am calling the get_user() function, which occasionally returns None, meaning that there is not user logged in. In order for the user to pay it is obligatory for them to be logged in.
This is the route in which the error is being generated:
@app.route('/success')
def payment_success():
session_id = request.args['session_id']
customer_session = stripe.checkout.Session.retrieve(session_id)
customer = stripe.Customer.retrieve(customer_session['customer'])
stripe_response = requests.get(url=f'https://api.stripe.com{customer["subscriptions"]["url"]}',
headers={'Authorization': f'Bearer {stripe_keys["secret_key"]}'}).json()
resp = make_response(redirect('/dashboard'))
if 'data' in stripe_response.keys():
if customer['id'] == stripe_response['data'][0]['customer']:
user = get_user()
user.stripe_id = customer['id']
user.cancelled = 0
db.session.add(user)
db.session.commit()
user_to_guild_handler(BOT_TOKEN, GUILD_ID)
requests.post(f'http://{DISCORD_SERVER_URL}/new_member_alert',
data=json.dumps({'user_id': user.discord_id, 'email': user.email}))
try:
coupon_key = request.cookies.get('coupon')
coupon = Coupon.get(key=coupon_key)
coupon.uses -= 1
coupon.update()
resp.set_cookie('coupon', 'USED', expires=0)
except Exception as e:
pass
return resp
Does anyone have any idea on why that thing could happen"
Exception details:
AttributeError: 'NoneType' object has no attribute 'stripe_id'
File "flask/app.py", line 2447, in wsgi_app
response = self.full_dispatch_request()
File "flask/app.py", line 1952, in full_dispatch_request

return self.view_functions[rule.endpoint](**req.view_args)
File "app.py", line 251, in payment_success
user.stripe_id = customer['id']
NoneType is referring to the None user object
Basically my question is: How can I solve this issue? What is causing it? Cookie expiration is set to one week
One possible answer I have is that they use incognito mode
But they wouldn't be able to login in the first place
plain zealot
Anybody familiar with node.js?

@plain zealot I can help with syntax and discord.js, idk about anything else
upbeat forge
For the user accounts database, do you want make a different table explicitly for users only or do you create a custom User Model?
Using django
I dont want to use the default login/signup form of django so what should i do?
balmy shard
Does django let you use html?
upbeat forge
yes
balmy shard
Idk how good it is
I went with the first thing I found
Swap out the background with whatever, shouldn't be too hard
upbeat forge
Actually django has a inbuilt way of dealing with forms, and i want to create a custom form but to do that should i use the default Users model or create a new one?
plain zealot
It is not about syntax though
upbeat forge
backend stuffs
balmy shard
@upbeat forge
Make a database with table called logins (or whatever you wanna call it) with an id, username, and password column
Definitely not the most secure, but it works for development
It is not about syntax though
@plain zealot wait til someones online I guess
lone galleon
hi, it's possible to start http.server (SimpleHTTPRequestHandler) and close him after one request? or after N request?

If I want to let the user upload a thumbnail image for a post and I want to be able to use it in different sizes, how should I do that?
I can save it in a small size like 125px by 125px but then quality will be super low when I need to enlarge it
So do I just save it as the original file and scale it down in the HTML as needed?

Hi, for DRF, is it okay if I only have JWT Authentication under DEFAULT_AUTHENTICATION_CLASSES or will I not work with sessions?
The problem I'm facing right now with sessions enabled is whenever the server restarts, it deletes all sessions and it doesn't seem to check if there's an existing JWT token so it just throws an Unauthorized error.

who knows how to use django
native tide
not me, I'm also trying to learn it
I want to make a comment web app, where you can select a user and give them a suggestion
native tide
is it a bad idea to host web server on localhost? I'm thinking of getting some of the new raspberry pi 4gb ram and making a cluster server
granite loom
would be better
wind walrus
I'm a high schooler just making a blog with Flask for fun
In that case is it possible to use Google Drive instead of S3 to store my images?
vague ibex
would NodeJS be better than django or flask?
@native tide Both are powerfull when used properly . The one you know how to use properly, can be a great asset for you.
rigid laurel
In that case is it possible to use Google Drive instead of S3 to store my images?
@wind walrus
You don't have to use s3, but Google drive won't work
wind walrus
Are there any free alternatives?
rigid laurel
Well. S3 gives you 5gb for free
So
S3
I'm not sure on what, but there probably are free ways to host or
vague ibex
is S3 free?
wind walrus
5GB is permanently free? Or like just 1 year or sth?
That's nice cos I won't be using that much GB anyway
wind walrus
As part of the AWS Free Tier, you can get started with Amazon S3 for free. Upon sign-up, new AWS customers receive 5GB of Amazon S3 storage in the S3 Standard storage class; 20,000 GET Requests; 2,000 PUT, COPY, POST, or LIST Requests; and 15GB of Data Transfer Out each month for one year.
Sorry my English is not my first language does that mean it's "for one year" only?
vague ibex
There is not any limit i suppose
I mean you can use those requests and 15gb data each month for one year
rigid laurel
Oh. Apparently so. It's very cheap though, every after that one year
vague ibex
so yeah, its for one year
wind walrus
True, would've been great if it was permanent but
vague ibex
Everyone company tries its best to provide the service but there's always a catch lol
Technically, I mean there won't actually be any company that will provide you unlimited cool features forever.
late fjord
what is the difference between react and django
vague ibex
React is a Javascript Framework whereas Django is a Python framework
late fjord
I know that
late fjord
that is what I don't understand
vague ibex
You don't understand front-end and back-end?
late fjord
yeah
vague ibex
React is a Javascript framework which proves to be a powerful alternative
late fjord
we can not do like django, i mean templates and urls ...
vague ibex
Django is a back-end framework and React is a front-end framework.
That's why you cannot use React like Django
late fjord
Imagine I wanna build an instagram clone what do I use?
if react what is it's job
django
or both
late fjord
yeah
vague ibex
For instagram clone, you need a client and a server.
late fjord
yeah
vague ibex
I hope you understand what they mean?
good.
For the Client side, You would use React
vague ibex
Client side == Front end
late fjord
got it
late fjord
yes please
vague ibex
alright.
Now after you have designed the client side, you will require it to send requests to the server side for retrieving data
For that, you will require a server to process the requests and send back reports
late fjord
for the client side do I use react to bring data from the server and display it
vague ibex
For a server to work, you need to do server-side scripting using any backend language
@late fjord , the front-end part is a large concept.
Let me explain to you what the front-end actually is.
late fjord
please
late fjord
yeah
vague ibex
you've visited spotify right?
late fjord
no, but I know how it works
late fjord
yes
vague ibex
Like the new releases, the new songs , etc. etc.
This is the front - end
Now, whenever I click on any of the song
late fjord
you send a request to the server
vague ibex
it will shift to the back end
The front end requests the server aka back-end
the server sends back the required code and the front end runs it.
That's it.
late fjord
got it
vague ibex
Now, the backend consists of server and a database too
For a database included server, the server , after receiving the request from client will check into the database(ofc through a piece of code) and then retrieve the data and send it to the client.
That's how it works ๐
I hope you understand, do you?
vague ibex
No doubt?
late fjord
but I have seen some people building react clone with react and firebase
vague ibex
react clone of what?
late fjord
I mean facebook spotify instagram ...
vague ibex
React is capable of making API calls (send request to backend), which deals with the data. React cannot deal with database or any datasource itself.
btw React is a library and not a framework.
vague ibex
I would suggest you to check it out.
It has a good explaination about firebase.
If you do not understand , just ping me ๐
vague ibex
Firebase is a mobile-backend-as-a-service that provides powerful features for building mobile apps. Firebase has three core services: a realtime database, user authentication and hosting.
^ there.
It is the first line the webpage says.
late fjord
thank you
vague ibex
basically, firebase is a mobile-based-backend
no problem!
It's my pleasure to help you :D.. If you need further help, feel free to ping me up! ๐
vague ibex
We surely can.
If the website has a client and a server that works, then we cannot.
React is only a front-end library.
got it? @late fjord
wind walrus
Btw a quick question - why would something like Imgur or Google Drive not work to store images? You can upload/retrieve files with Python right?
Imgur or Google Drive as opposed to S3 that is
late fjord
yes, but can u give me an example of a website without server
vague ibex
sure
@late fjord btw do not use the words - "without a server"
Every website is hosted on a server which keeps it alive
wind walrus
Lol my first website was just HTML and CSS no backend at all
late fjord
yeah got it, so, can a website exist without backend
wind walrus
Like a simple <h1> Hello world </h1>
vague ibex
Let me grab a link asap.
yeah got it, so, can a website exist without backend
@late fjord yup!
It is a gaming blog.
It only has a front-end and a CMS by blogger (if that really counts lol)
late fjord
thank you so much you helped me a lot I'll check it, btw, can I send you a friend request
vague ibex
sure ๐
It's my pleasure to help people clear their doubts.
I do myself have a lot of doubts in general.
A quick tip: "Always try to clear your basic concepts when progressing further"
wind walrus
can I ask a quick question as well
wind walrus
why would something like Imgur or Google Drive not work to store images? You can upload/retrieve files with Python right?
vague ibex
I've accepted it.
wind walrus
I'm just a high schooler coding for fun, so this website won't be important or anything
Imgur or Google Drive as opposed to S3 that is
vague ibex
why would something like Imgur or Google Drive not work to store images? You can upload/retrieve files with Python right?
@wind walrus Google drive stores images?
wind walrus
Yeah you can upload any file to Google Drive
vague ibex
yea?
wind walrus
can't we just use Google drive or Imgur instead of paying for S3?
It's just a website for fun so it's not serious or important or anything just a blog
merry geode
For simply displaying images, you can use Imgur probably. I have not tried. Google drive might be difficult though, it may not allow embedding the image in another site. Worth a try though,
wind walrus
So what can S3 do that Imgur wont be able to do?

Does anybody know how to use file feilds in django
late fjord
just ping brunckek he know a lot of stuffs he might help you @unique hill
unique hill
@flint breach i have a doubt regarding file feilds in django
can you help me
@late fjord thanks
late fjord
you are welcome
I am trying to make a form to ask a question, I set initial to the asker to the request.user but it is not saving to the database, I don't know why @unique hill can you help me with this
this is my forms.py:
from django import forms
from .models import *
class AskQuestion(forms.ModelForm):
class Meta:
fields = "__all__"
model = Question
and this is my views.py:
@login_required(login_url='/user/register/')
def ask_question(request):
form = AskQuestion(request.POST, initial={'asker':request.user})
if form.is_valid():
form.save()
return redirect('/questions/')
return render(request, 'questions/askquestion.html', {'form':form, })
yes it does
@unique hill
unique hill
then checkout if the form has the appropriate action
and also if the button is of the type submit
late fjord
I didn't set the action
unique hill
that's why i believe its reloading
late fjord
<form method="POST">
{% csrf_token %}
{{form.title.label}}
{{form.title}}
{{form.text.label}}
{{form.text}}
{{form.tags.label}}
{{form.tags}}
<input type="submit" value="Ask">
</form>```put a action
late fjord
what is the role of the action
unique hill
to check whether that is the problem
late fjord
do I set it to ""
unique hill
action means your form knows where to go when this form is submitted
if there is no action than it will keep on reloading the current page
late fjord
so what do I do
unique hill
what do you want to do after the ask button is pressed
late fjord
I want them to be redirected the page of the question
unique hill
try using action for this ask_question function
what is the name in urls.py for ask_question function
unique hill
action={% url 'askquestion' %}
late fjord
just {% url 'askquestion' %}
unique hill
show what changes you made
late fjord
maybe because the form is not valid
unique hill
in the html file
late fjord
<form method="POST" action="{% url 'askquestion' %}">
{% csrf_token %}
{{form.title.label}}
{{form.title}}
{{form.text.label}}
{{form.text}}
{{form.tags.label}}
{{form.tags}}
<input type="submit" value="Ask">
</form>
this looks fine
put a breakpoint at form
wait a sec
what is the name of your table in models
where you want to save this data
late fjord
and my urls.py:
urlpatterns = [
path('', questions, name='questions'),
path('ask_question/', ask_question, name='askquestion'),
]```where breakpoint
late fjord
I don't get you
unique hill
do you know how to debug
late fjord
no
unique hill
very good
so search on youtube
how to debug a django code
do u use vs code or pycharm
late fjord
I use vs code
I actually removed the instance and it is saving
do you know how to the instance correctly
please tell me that you do
@unique hill
unique hill
your code is working now??
late fjord
after changing python form = AskQuestion(request.POST, instance={'asker':request.user})
to:
form = AskQuestion(request.POST)```but overhere it says initial
i am actually not familiar with this instance thing
this might help

Hey, hope I'm in the right channel. I'm looking to build some API for an ELO system (specifically using Docker, but that shouldn't change much from the python side). I've been looking at Flask to build the API. What I'm not sure about is how to build that API. I want some private routes for registering that a match has happened and should update the ELO. But I also want some public API at some point for other services to be able to read the data. Is there a way to do this in Flask, or would it be better to separate the two into two different apps?

Guys what is the point of name in url definition in my urls.py?
Like :
path("".views.function,name="something") #What does the name do?
You can easily refer to that view in your template
dapper tusk
when in a template, you can link that url with {% url 'something' %}
and I think redirect can also use those
glass sandal
Oh
So I can do a href like :
<a href="{% url 'something' %}">Goto something</a>
And this will point to the main page right?
Since something's url is "" in this case

Hello people,
Does someone have a good tutorial to help me setup a Flask app with Apache WSGI without using virtualenvs?
I tried it myself but I keep having a ImportError: No module named flask in the Apache logs (of course the Flask app works fine if I run the standalone server, and I already tried making sys.path.appends in the wsgi file)

Maybe print out sys.executable to see what python Apache is running from

I am having an issue using djangos LoginRequiredMixin, I get a circular imports error if I set login_url to reverse('test') for example, also even if I hardcode the url, it redirects me to some iwerd non existing url, could anyone help me with this?

Is there someone who know about MYSQL and displaying data in a table with flask?

sudden grail
Hey guys, i really need your helps.
Im making a project and im confused about design
so,
what i got:
the layout matters
as you can see, there are threads on the right
what you say, where should they open up?
if you click on a thread then it should move into the middle
upon the base chat
or stay in the right panel?
which is more comfortable?
this is it if you click on a thread
the right side changes
but is it okay to see the chat there? or would it be more intuitive to see just one chat in the middle,
base or a threaded chat
What do you say? Any response would be helpful :/
glass sandal
I'm not a UI designer but I'd rather the text input to be in the chat's div
Or the chat should be centered on the screen
sudden grail
@glass sandal yees-yes, this is just the layout. On the right side there will be a chat panel like in the middle if i choose this way.
But should it be there?
or open in the middle
glass sandal
I mean , I am not a UI designer as I said :(
sudden grail
yeah, i know ๐ but thanks
I am not as well, just thinking about best approaches. If it'd open in the middle, then you cant make mistakes and send messages to the wrong chat(because you might send if you see two chat opened)
but if you need to search for some infos, then you have to go back, search in the base chat or wherever
and open up the thread again
both has pros and cons
but which one's pros are bigger and cons are smaller? thats the question
personally you, @glass sandal , what would you use with more "passion", which one?
glass sandal
Uhhhh...Ummmm... I would say remove the div that is on the right side , and move the chat to the center
And you can do another chat in the dashboard
Like the left side
sudden grail
and then on the right u can see the list of threads, and if you open one, then it shows up in the middle. Otherwise you see the base/"main" chat of the channel in the middle
glass sandal
Oh I see
sudden grail
Threads are meant to organize the main chat into topics
you know
and organizing infos
around topics
to catch up later if you go on holiday or something
glass sandal
I mean , it's 00:21 here and I'm being a lil dumb . I may not be able to answer rn

Simple Flask question: do users see any print('something') commands that are run in the code?
I have quite a few print() commands for development and bug fixing purposes, but I don't want my users to see those, even when they go looking
twilit zenith
by users do you mean other developers? or webapp users? @nova crest
mellow tide
@nova crest prints go to the console, so unless you are doing something strange, generally, your user won't see print statements (unless they are running said server)
nova crest
I was talking about Web App users
I figured the prints would only go to the server console, and not reach client side
thanks for the confirmation!
mellow tide
@nova crest fwiw, generally, when running a server, you don't want a bunch of prints to console though because daemons typically don't run in an active console (they are usually background jobs) so you usually want to do logging to a file rather than to a console... but for dev purposes, that is fine
not to mention, administrators typically have a set number of places to go hunting for logs
nova crest
@mellow tide Fair point. I will eliminate the prints when I'm ready for prodution

Hey guys. Is there any datastructure in js to implement a queue with O(1) time operations?
List's shift() operation has O(n) time complexity
vestal hound
which operations?
digital kayak
enqueue and dequeue
rigid laurel
An array
Popping and insertion are o(1)
Oh wait
That's a stack
No. An array will work
vestal hound
I'm sure there're tons of implementations, but it's trivial to roll your own
vestal hound
You just need to use shift instead of pop
@rigid laurel p sure that's O(n)
rigid laurel
Reading about it, it's engine dependant
vestal hound
I think common implementations would leave it O(n)
it is possible to have constant time shifting but I don't think that's what most common use cases require
rigid laurel
Yeah. You can't rely on it. I'm surprised js doesn't set out these requirements the way python does
rigid laurel
I can't find a decent source for time complexity of operations in JS anywhere. Shift/Unshift seem to be pretty much always O(N), but I'd like to see a reasonable place have done the research
cold anchor
JS is just a spec, so the time complexity will depend on the underlying implementation of the JS engine, which varies between browsers
rigid laurel
Sure. But python specifies time complexities
And is also just a spec
Although it does have one main implementation

cold anchor
here's the v8 engine for example, it looks like they have a "fast" version of array shift as well as a slow ( O(n) ) version depending on if they can use the fast one https://github.com/v8/v8/blob/4b9b23521e6fd42373ebbcb20ebe03bf445494f9/src/builtins/builtins-array.cc#L563-L592

Hi y'all, I'm not quite familiar with JavaScript and the legacy code of the Flask App that i have here, but maybe you can help me to figure this one out:
I have a Slider with control buttons that lets you cycle through a few pictures. I want to automate this slider so that it executes the function for the next image on click or does it automatically if no click is received within 3 seconds. I think I identified the relevant function:
$(".hero-wrap-text-slider-holder a.next-slide").on("click", function() {
$(this).closest(".hero-wrap-text-slider-holder").find(sync2).trigger("next.owl.carousel");
return false;
});
$(".hero-wrap-text-slider-holder a.prev-slide").on("click", function() {
$(this).closest(".hero-wrap-text-slider-holder").find(sync2).trigger("prev.owl.carousel");
return false;
});
How can I add something like an OR Operator to wait three seconds before triggering the next slide?
I guess this is some sort of Boostrap Carousel deviant if that helps
if this is the wrong place to ask, since this is a python place, please just ignore the above

(refreshing doesnt work, but closing and opening the tab again works..., but i wanna update the audio without refreshing nor closing the tab) any solutions?

Stick that in the Javascript and see if it works

is it another file location problem

Hmm let me clarify my words
If you wanna run a Script
You should be in the same folder where the script is
Or run python3 'the absolute Path of the script ' run server
That can be a little hard to understand ^^
Do you know the path where your script 'manage.py' is?

Can you copy paste the whole path of your project folder?

C:\Users\blufl\Desktop\dexbotx\pyshop/manage.py

Use python3 C:\Users\blufl\Desktop\dexbotx\pyshop\manage.py runserver

i legit just did that
but like nothing happened
tho lemme try it again
it shdu give me a webadress to go to right @hollow linden ?

Anyone who know React, how to solve this:
Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.
Check the render method of `Header`.
Here is header
import React from 'react';
import { Navbar } from 'react-bootstrap';
export class Header extends React.Component {
render() {
return (
<Navbar>
<Navbar.Header>

@modest scaffold Something is missing! are you using Jinja?
@modest scaffold is you website https?
@valid cypress https://stackoverflow.com/questions/31852933/why-es6-react-component-works-only-with-export-default
That will help

@hollow linden its not https i dont think so anyway
@hollow linden what is missing

I don't know ^^

no django

okay Django
modest scaffold
missing crsf token for some reason
even though i have it in the html and im returning a render object
quick cargo
You seem to need to get the template object then pass it the context first then the request
valid cypress
This is still not working when I changed this to default
modest scaffold
@quick cargo cant i use a render() function though
In the corresponding view functions, ensure that RequestContext is used to render the response so that {% csrf_token %} will work properly. If youโre using the render() function, generic views, or contrib apps, you are covered already since these all use RequestContext.```nvm its working now
i think it was somthing to do with broswer cache
hollow linden
All fine ^^

in django can you have variables inside template tags like this {% if apples|slice:"{{x}}" %} where x would be a variable
bleak bobcat
Yes you can but you'd remove the " and {{}}. However don't put logic inside templates

HEy guys
I have an issue
@app.route("/") #Homepage
@app.route("/home")
def home():
return render_template("home.html", posts=posts) #Use render_template to return html files containing the code for the pages.
@app.route("/about") #About Page.
def about():
return render_template("about.html", title='About')
@app.route("/register", methods=['GET', 'POST'])
def register():
form = RegistrationForm()
if form.validate_on_submit():
flash(f'Account created for {form.username.data}!', 'success')
return redirect(url_for('home'))
return render_template('register.html', title='Register', form=form)
@app.route("/login")
def login():
form = LoginForm()
return render_template('login.html', title='Login', form=form)
if __name__ == "__main__": #__name__ is __main__ if we run this directly.
app.run(debug=True) ```so this is a small snippet of code
but when it should redirect it doesn't it just reloads the page

redirections do not always work on all browsers afaik
so you have the fallback link
if the redirection does not redirect, the user can still click the link

I have an Instagram account and I may change its username in the future
But I want to link it to my websites
Is it possible to get a link to the account with the account ID or something instead of the username so that I wonโt have to go change the code for my website every time I change my username?
wind walrus
But wouldnโt that still need to have a link that points somewhere?
And in the link will be the account username so...
native tide
The best I could do would be to have a clickable instagram logo
but I am still new to this web dev stuff so yeah.

Yeah, I canโt find a better solution, thanks for your time

Flask btw
strong oriole
which one is easier to learn
django or flask?
void leaf
Flask
Does anyone know if thereโs a way to import a variable defined outside of the webpage function into the html template in flask?
native tide
With the delimiter {{ }} or am I misunderstanding
void leaf
So Iโm making a function that web scrapes and grabs a value, I want to show that value on the flask webpage.
@native tide doesnโt using the delimiter {{}} require the variable to be defined in the page function
mellow tide
you could assing the scaped value to a global variable and then use that variable in your page function @void leaf
but now you are taking the risk of blocking on a scrape
void leaf
Thatโs what I did. The scraped value is x . Do I need to put x in the page function arguments
mellow tide
@strong oriole flask by a long shot lol ... but that is because django includes EVERYTHING you need. Flask you have to lego it together
Thatโs what I did. The scraped value is x . Do I need to put x in the page function arguments
@void leaf either as an argument, or defined as a global variable
strong oriole
wdym lego it together
void leaf
Thanks Iโll let you know if it works @mellow tide
mellow tide
puzzle-piece it, you have to find and build functionality outside of the original intent of flask
native tide
Sorry bro I'm not that experienced to answer
mellow tide
flask is great for hosting sites, but doesn't include user auth, a database, it's not really that great for APIs unless you use another plugin
basically, you have to find the plugins you want with flask, whereas, Django is "batteries included" and they all exist, but you have to learn all the parts
it's ultimately more work to use flask, but you get to break it up a bit
native tide
Guys if you have a DataRequired() validator, if the form is empty, it will show you a box saying 'Field empty' right?
Is that the same for other validators such as Length()?
mellow tide
i would assume, but without looking at it, i don't know lol
strong oriole
soo django is more noob friendly as it has everything but flask is just some bits i need to use to create something big did i get you guys right?
native tide
I think flask is more user friendly but there are plugins for stuff such as authenticating users instead of it being included in django
strong oriole
so final decision flask or django is easier to learn while being good enough to do something useful
xD
dark agate
flask is more friendly for beginners
native tide
Yea I'm a beginner I'm having a good time with flask
Except for the validators :(( still unsolved

hey so rn i have this view where i post a message in a forum:
class NewMessage(LoginRequiredMixin, CreateView):
model = Message
fields = ['content']
def form_valid(self, form):
form.instance.author = self.request.user
thread_path = self.request.path.replace('/new', '')
form.instance.thread = Thread.objects.filter(pk=int(thread_path[thread_path.rfind('/') + 1:])).first()
return super().form_valid(form)
```and i have the middle two lines in `form_valid` to get the current forum
the thing is, would there be a more efficient way to do this? (ping plz)If I give some flask code can you guys try to run it and see if it works? Because I'm getting no errors the code matches documentation and it's not working for me

So, the issue I am having is that EqualTo() is not showing errors when the password fields do not match. Can you possibly see if it is showing you anything, if the password fields are different?

guys, what is the best way to schedule tasks in flask?
cold anchor
I've had success with flask crontab in the past https://github.com/frostming/flask-crontab
rustic pebble
@cold anchor what are the disadvantages of using crontab?
cold anchor
the most granular time is 1 minute
you need to make sure the user running the command has permissions to do so
and you're limited to the health of the server it runs on
native tide
I have a question involving security with Django. A project I'm working on with it is going to be using React components in some places, for instance a private message window commonly seen in a lot of forums. For the inbox for example, the component will simply make an API call to the server of the user's ID, and get back a paginated list of messages. The necessary data for JS is fed in through the template as context, simple enough right?
This is the part that loses me though... can't this functionality be easily manipulated, or if not, what is preventing it? For example, someone locally changing their html data, running it, and then getting someone else's inbox messages (provided they have another person's primary key), or doing the same with a POST request, changing data that isn't theirs. Any nudge in the right direction would be much appreciated.
cold anchor
only give load the messages of the currently authenticated user, then the security will be as good as your authentication system

I want to run a background task where it refreshes the state of membership for my members, I have around 1300 members connected through Stripe
I need a way to refresh their data every 12 hours

Instead of installing something like celery
wind walrus
If I already use flask-SQLAlchemy for my databases should I try making a nested comment thread system with SQLAlchemy too?
Or would Postgres or MySQL be better
crystal quartz
@rustic pebble celery is a pain and overpowered for what you need. Crontab is the right answer here. You can either set it up locally to run on your server, or set up an endpoint through flask/django and have a service like setcronjob senda request to that endpoint when you specify.
rustic pebble
Yup
