@woeful trellis sir sir its working haha nice nice thank you @woeful trellis @vestal hound 😅 👍
btw why do i need to get the count on the view instead in the template? is it illegal?
or its the difference between model views and def view?

Anyone know how Sanic is failing to parse this requests body? I'm making the request /w aiohttp.
async with session.request(

headers={
"Authorization": ("X+"
"X==")
},
data={
"method": "GET",
"url": "https://partybot.xmistt.repl.co"
}
) as r:
It seems perfectly fine to me.
This is the response I get exactly:
<!DOCTYPE html>
<meta charset=UTF-8>
<title>400 \xe2\x80\x94 Bad Request</title>

<h1>\xe2\x9a\xa0\xef\xb8\x8f 400 \xe2\x80\x94 Bad Request</h1>
<p>Failed when parsing body as json\n</p>
Sending the request from Postman for example works just fine.

Hello guys, I'm building a simple api with Flask with just few routes, I'm using flask-restful and I'm looking for "the best" architecture to build it, I'm currently looking to use Blueprint with flask restful and I wanted to know if it is a "good choice" or if there is something else I should check. The implementation is not a problem just want to know if there is other thing I should be aware of when thinking about architecture an api with flask. thx !

Dumb Q.... how much of Django is based on templates/jinja? I’m switching my pages from just HTML to Base.html/Jinja.
lethal orbit
A good chunk of the Views.
But it is fully optional. I usually use Django only as an API
frozen python
@lethal orbit is it annoying tho that when you have 5 pages... you might have to change the script if something gets updated?
lethal orbit
What do you mean?
If your data is dynamic and you code the templates to handle it, you don't really need to update the scripts.
frozen python
@lethal orbit I know, I thought you meant “optional” as in “no”, but ok! But tho.... how easy could my routes that I already have, get messed up when I switch to Jinja way?
fringe imp
I have a question. I want to make a http request to add a porduct to card. Every time if i send the request i get an error ACCES DENIED to the website. I try it on footloker.de
lethal orbit
@lethal orbit I know, I thought you meant “optional” as in “no”, but ok! But tho.... how easy could my routes that I already have, get messed up when I switch to Jinja way?
@frozen python Are you switching from static HTML or from the Django Template Language? Either way, it shouldn't mess anything up...
quick cargo
Fun fact, Jinja was originally based on Django as a superset of Django's engine

I am using flask. I want to extract an access token from the redirect url from an implicit grant. Information is returned essentially as query strings, but rather than starting with a ?, it starts with a #. request.args.get("access_token") will not work because of that, and when doing request.url or request.full_path, it ignores the # and every after it. How can I get the information?
@ me when responding, please.
As an example:
http://127.0.0.1:5000/discord/#access_token=XXXXXXXXXXXXXXXX&token_type=Bearer
I would want to get the full url at the very least, because then I can extract the token with regex.
frozen python
@lethal orbit I’m just trying to hook up “main.html” as my Django main page for everything to inherit from. I think I’ll do a “test.html” to then see if it hooks up right, then I’ll apply it to my pages I have working. I have the routes and view working, I don’t want to mess them up

how can I make HTTPS requests during development?
quick cargo
https://url.com/here
zealous siren
there is also FastAPI for building pure RESTAPI SmilingDude
quick cargo
if you mean make the server itself SSL and HTTPS then you could use something like Cloudflare's flexible system to stick it behind or just slap the cert files to the server if it supports it
you'll need some sort of SA tho in general for HTTPS and SSL
mellow tide
yeah, I would have suggested that Rabbit, but he specifically asked for Flask+React lol ... i don't agree, but who am I to judge
quick cargo
Cant argue with a good old Flask api tho
mellow tide
well ... i CAN argue it lol
quick cargo
dead simple to setup tho maybe not as powerful as FastAPI
cant get away from just how awesome FastAPI is tho
mellow tide
that is why I liked Falcon for so long. Was flask-ish with none of the UI crap i would never use lol
quick cargo
Never used Falcon much only for 1 or two odd things
mellow tide
fastapi didn't exist when i was using python for these things lol
quick cargo
Sanic seems to be my main goto
tbf i imagine ASGI was either non existant or very new at the same time
mellow tide
when i write an API, I'm always in Go
quick cargo
Im just switching from Go back to Rust now 😩
mellow tide
yeah ... I remember when Asyncio his the scene ... and then aiohttp ... and all of that craziness ... needless to say, none of it was prod ready lol
quick cargo
came along way
mellow tide
it sure has lol
I still find writing APIs too cumbersome with Rust yet, so i've not done a lot there
quick cargo
Hyper or Warp are my main go to's but yeah i personally wouldnt ever go to it for API stuff
So much stuff todo even for a very simple system
equally its the reason why im going back to rust over go
mellow tide
I've considered writing an actual, good, api framework for rust, with a sane server default ... I just haven't yet
quick cargo
I think the thing which will make rust viable will be Rocket
craggy trout
tried Rocket yesterday for Rust, but started having problems
quick cargo
By fat the cleanest Library for Rust imo
craggy trout
with my WSL setup probably
mellow tide
lol @ by fat
quick cargo
tho i gotta say Warp is very clean aswell but a different style
native tide
Rocket will run on stable next release
quick cargo
think warp is alot lighter than Rocket aswell
and async
tho i think rocket was going to async again?
i cant remember
quick cargo
actix is a bloat machine tho overall
mellow tide
my problem with the current ecosystem is the focus on being a full web framework ... i have no interest in any of that lol
quick cargo
200+ deps by default when using the web build + Awkward for windows development + rather confusing middle wear system
@mellow tide Lack of good Database systems aswell
from what ive heard diesel is pretty poor and requires manual migrations
native tide
Haven’t tried rocket in a while, how many deps does it require?
mellow tide
eh, db's i don't have a problem with, i've no issue writing raw SQL statements
quick cargo
same here
native tide
My toy is probably over 300
quick cargo
Raw SQL you know exactly whats going on at any time
mellow tide
Dependencies
atty ^0.2
base64 ^0.12
log ^0.4
memchr ^2
num_cpus ^1.0
pear ^0.1
rocket_codegen ^0.4.5
rocket_http ^0.4.5

Rocket 
craggy trout
so i've mainly been a node/react/aws guy for the past 4 years and have been looking to get out of my comfort zone and add a portfolio project in a language/framework i've never really worked with and had settled on Python/Flask, but now you guys are making me reconsider Rust/Rocket or Go/whatever
mellow tide
@craggy trout Just Go, no framework needed 😄
quick cargo
you loose alot of development speed for the sake of performance
native tide
If you want full control, rust
quick cargo
saying that i found Rust is actually really fun to use
mellow tide
yeah, Rust is a lot of fun, but it's a lot slower than other languages in that space
craggy trout
yeah, rust in general kind of reminded me of more functional languages where the bulk of dev time is front-loaded
quick cargo
I love go for the runtime but i hate it for the runtime errors
mellow tide
development is slower i mean
quick cargo
so easy to slip up with Go's system but its a nice balance of performance and dev speed
craggy trout
rather than back-loaded with fixing bugs that pop up later
native tide
Strongly statically typed languages
quick cargo
I agree with rust's system of show all the errors at once at compile rather than at runtime
mellow tide
Go sits closer to Rust on the frontload/backload deal, but there are backload things if you use interfaces/reflection all over the place
quick cargo
by far the nicest thing about it is you can almost have no chance of runtime issues if it compile in rust
still possible for sure but if done right its rare
mellow tide
I've had issues with generics ... but mostly because i forgot how to use them from using Go for so long lol
quick cargo
another issue i had with Go is switching between it and python
how many lines ive go X := xyz by accident in python
craggy trout
hmm. maybe a Rust backend with Elm front-end ... that would take forever
mellow tide
that sounds no fun lol
quick cargo
i recon Rust's eco system for it will grow, id say its at the a similar stage as asyncio and Aiohttp was with Python a while ago
tho more production ready its certainly rough around the everywhere in places
mellow tide
yeah ... you have to be very careful with prod Rust right now
simply switching out shitty C libraries is a good use case, but there just isn't a lot of productivity outside of that in a prod system yet
I need to take a look at the windows binding though ... if microsoft actually keeps up with that ... it'll take the scene by storm
quick cargo
Im interested to see how Hyper is implementing HTTP3
there is some rough designs for it but that'll be interesting to see
mellow tide
lol ... i just want to see HTTP2 in browsers, i can't even fathom HTTP3 yet lol
quick cargo
yeah
did think that when i saw it, considering 90% of the web is still http/1.1 anyway
tho thats the way the internet is ig
craggy trout
anyone used Python/Go/Rust with DynamoDB?
craggy trout
when i've brought up dynamodb in other discords, i've had rocks thrown at me, so this was just a test
native tide
anyone use jinja with fastapi?
mellow tide
eh, dynamo isn't my favorite ... (given that they flat stole the IP from mongo lol), but it's usable. I tend to steer folks away from AWS if I can though
but that being said ... i've never had a massive data loss using Dynamo, and I have with Mongo ... sooooo
craggy trout
really wanted to use mongodb in my next proj, but i've gotten so used to dynamodb and the "single table" approach that i'm not looking forward to it
mellow tide
in what context @native tide
native tide
for some reason get_flashed_messages() works with flask but converting the exact code to fastapi seems to make it not like to work
not much about it online, wondering if anyones run into the same issue
mellow tide
oy, yeah IDK, again, I'm Go for web these days 😄
native tide
aha, wise choice, need to learn MUX at some point
craggy trout
why steer others away from AWS? vendor lock-in? price? piss poor documentation that'll drive you insane over and over again?
or is it that they're pretty much replacing the old guard of evil corporations, they're becoming the biggest evil megacorp
quick cargo
Scylla or postgre are my mains now
Mongo is great for beginners but pretty slow and holy fuck is so awkward to edit things with
craggy trout
Amazon is basically Shinra now
zealous siren
Sure, but benefit of cloud databases are hard to pass up
mellow tide
why steer others away from AWS? vendor lock-in? price? piss poor documentation that'll drive you insane over and over again?
@craggy trout yes ... yes to all of this ... lol
craggy trout
yeah, my last job was full blown serverless stack: appsync, s3, cloudfront, cognito, lambda, dynamodb, elasticsearch in ec2, transcribe, translate, etc, etc
in many ways, it was beautiful, especially once you got things working
mellow tide
yuck ... $$$$$$
craggy trout
but getting things working was quite difficult a lot of the time
zealous siren
We do alot of serverless on Azure at work, it has it's benefits as well
j4ng5y not really
rapid development can override the cloud run costs
craggy trout
it was actually cheaper than what they had before
zealous siren
yea, containers/VMs have set bottom cost where some of this stuff can be pure consumption cost
craggy trout
all in aws anyway in ec2
mellow tide
i suppose if your stack was designed for it, you can get away with it ... but i've seen time and time again that lambdas that spawn lambdas that spawn lambdas (etc...) end up costing far more than EC2
zealous siren
not sure why you would do that
mellow tide
idk ... architect there was an idiot lol
craggy trout
appsync fixes a lot of problems
zealous siren
but that's not cloud fault
craggy trout
if you use it correctly. i didn't consider AWS serverless viable when you had to rely on just API Gateway + Lambdas
mellow tide
oy ... yeah apigateway is ftl
craggy trout
partially because i just hated API Gateway and refused to learn it :p
craggy trout
only problem with AppSync is kind of a lot of boilerplate ... and the webui would slow down tremendously if you had a decently sized gql schema ... hence almost never using it except for the occasional instance where it was useful for debugging
mellow tide
the reason we had the step functions though ... was because instead of using an actual ETL pipeline, they were using lambdas because serverless ... and it was idiotic
and the runtime limit cased them to spawn lots of sub functions
but i've seen many a company while doing consulting that was trying to shoehorn serverless in places it didn't need to be
thus my beliefs
obviously, aws wasn't going to stop them from giving them a truckload of cash lol
craggy trout
i've seen a small business (less than 20 employees and less than 3m in yearly revenue) paying 5k/month to AWS
which might seem reasonable in certain cases, but in this one it was waaay too much. ms sql and large ec2 instances were the bulk of cost
for a web platform that currently doesn't escape free tier aws limits
well, in some casees
still a couple hundred a month for s3
mellow tide
i did a consulting gig with a startup that couldn't figure out why they were spending 20k/mo with aws (i guess they had never heard of the cost dashboard, but w/e) ... turns out they were running basic workloads on P3s
and also, because the CTO they fired was running crypto miners on all of them
craggy trout
haha
mellow tide
they tried to hire me as CTO afterwards, but i was negative interested lol
craggy trout
man, i should have tried that at last place .. they had a lot of production workstations for video editing with quadro cards that stayed on 24/7.
mellow tide
lolol
craggy trout
not sure if quadros are good for that, know very little about crypto mining
mellow tide
basically it depends on the coin algo lol, but even if it doesn't work that well for bitcoin, it's sure to work well for one of the altcoins
you see a lot of the malicious miners going for monero and stuff like that because it's CPU cycle based, less GPU
craggy trout
i heard kim jong un likes monero
wonder how someone would go about trying to steal all of it
mellow tide
i've heard he is dead/in a coma ... don't believe everything on the internet lol
craggy trout
eh, it was just the idea that monero is harder to trace so NK liked to steal it
mellow tide
yeah ... i like zcash for the non-traceability, but the value is very low lol
anyway ... i've steered this convo WAAAAAY off topic lol
so web development is fun

Is initilizaing a flask app in a init.py file good?
mellow tide
@noble star doing anything in an __init__.py is generally an anti pattern or at least a code smell and should be avoided
noble star
instead of init.py, should I just create a helper.py file where common variables will be stored? @mellow tide
mellow tide
Common variables? Not sure what you mean for sure, but if you mean more like global app variables, those should probably be avoided too lol
noble star
like the app = Flask(name). where I import that in different files
mellow tide
For flask, I generally will have a whatever-i-am-calling-my-app.py to let both myself and others that may work on my code where to start
noble star
So if you had a blog.py (for example), you would do all initialization in that file (question 1) and import what you needed from other files? (question 2)
If you have seen Corey Scafer's Flask tutorial, it basically looks like that (Package Structure Video)

I've not seen that blog, I'm just letting you know how I write greenfield apps at work :)
But yeah, I put all entry point code in the file that looks like it is the root of everything

What information is the form collecting? What is it doing with it? If you're storing it in a DB, what DB?
Databases are pretty good at locking tables, and preventing duplicate entries at the same time.... you don't normally have to deal with queues.
past cipher
token and email, but if the db is locked while it appends new information, then I shouldn't have anything to worry about
i didn't know tables lock, thanks for that
lethal orbit
Well, they usually lock the table, but if you don't have "unique" constraints, it may enter duplicate entries.
And it depends on your actual system...

error = 'Invalid Credentials. Please try again.'
else:
session['logged in'] = True
flash('You were just logged in!')
return redirect(url_for('staffdashboard'))
return render_template('login.xhtml', error=error)```I am pretty sure that what flask promotes
swift sky
#app routes for webpages
@app.route("/")
@login_required
def staffdashboard():
return render_template("staffdashboard.xhtml")```oh u using flask-login

this code is causing me to redirect to the login page after I log in
im actually not @native tide
I should be, but I want an MVP before I refactor

oh ok continue with ur work , gl

Is this an okay spot to ask about a web scraping question? I'm trying to write a very "fragile" web scraper that breaks (intentionally) when changes are made, so that I can be confident it didn't "miss" anything. I am trying to avoid missing fields or boxes that may appear only occasionally, so I want to log any unexpected structures. I'm using lxml.html at the moment, but the API feels a bit ... clunky in places, for certain tasks. Like, it's great for finding things you know are there, but seems shakier for looking at things you don't expect.

I am realizing that if someone else were to get the information in the web cookie, that they could edit the dashboard as the user whom they took the information from. How can I secure this better?
My current idea is to store the data in a database instead, and the cookie/session would just store an custom encrypted session ID, and that session ID would be used to get the info. The database would also store the IP of the user that was logged, so that if the session ID was used in the cookie from a different IP, the application would force them to log in again. Is this a solid method, and are there any issues/improvements I should know of? I am using flask by the way, and would use request.remote_addr for the IP.
@ me when responding please.

@north perch not sure what your question is
if its about logging, create a txt and append errors to it
north perch
Yeah, I'll elaborate a bit, sorry -- Say I'm at some node in the element tree, and I want to make sure that the only further elements are ./ul/lia/a -- precisely only that tree, nothing else, no siblings at any level. The syntax for doing this with lxml.html seems very ... verbose, to say the least.

Hi everyone, I have to improve my solution. I have an sudoku algorithm and I want to be able to type on website, run the algorithm a return it. Is there a way to somto create 81 inputs without typing them each by each or generating the entire html in another code (for loops to generate the table, th, td). How would you do it

I have a web app that connects to the Pet Finder API. It requires an OAUTH token for any requests. I have a Class that gets the token, as well as generates an instance that I can use to handle all requests. Right now I create the instance at the beginning of my Django views.py so that it’s globally available to all of my methods.
The only problem is my token expires after an hour, and the API doesn’t send a refresh token with the initial request. I need to find a way to create a new instance of the class every hour.
I’ve been reading up on threading and think maybe it can be used to solve my issue, but I’m not familiar enough with it to really figure out how. Maybe threading.Timer()?
I tried putting the thread.Timer under the init of my class to see if I could get it to run the init again and get another Token, but that didn’t work.
If I did something like:
def Token:
x = PetFinder(keys here)
threading.Timer(3550, Token())
return x
pf = Token()
Would that work? Or would the method wait for the timer wait to complete before it returned x?
past cipher
why not just create token everything the function is called ?
pearl latch
Because in order for the whole app to function, I have to have a valid token. I guess I could remake a new instance of the class every under every method, but I have a feeling that would sort of abuse the API and I’d get my keys revoked.

how to delete a file on a s3 bucket with boto3
i tried getting the object like this s3 = boto3.resource("s3") obj = s3.Object("bucketname", "path") obj.delete()

modest scaffold
that is what there documenatation says

<blackleitus> https://dpaste.org/uuYn
modest scaffold
but does this mean that it only deletes the objects if it is null? Removes the null version (if there is one) of an object and inserts a delete marker, which becomes the latest version of the object. If there isn't a null version, Amazon S3 does not remove any objects.
@hallow jacinth

I don't think that is how you pull a file from s3. I only looked at the documentation for like 2 mins. I'll look again after classes
ah, I see it now

How do you guys learn TDD and stuff like that? Work experience?
hallow jacinth
try
client = boto3.client("s3")
obj = client.object(bucket="bucketname", filename="filename")
obj.delete()
if that doesn't work then try
client = boto3.client("s3")
obj = client.object(bucket="bucketname", filename="filename")
obj.delete(MFA='string', VersionId='string')
If that doesn't work, then I am not sure if this is the proper way to go about deleting a file. Usually when I have an issue with boto3 I just play around and read their documentation
@modest scaffold
also with boto3 you dont have to put things like bucket= or filename= just make sure things are in correct order, otherwise set the arguements
acoustic oyster
How do you guys learn TDD and stuff like that? Work experience?
@native tide projects! I do not often do test driven development, but I believe the principles behind it can be seen in a simple way from doing code challenges, i.e codewars. The best way to learn imo though is to just do it, think of a project, and develop it using TDD.
native tide
For example, I'm building a website, I just don't see how I can incorporate TDD. What can I write tests on? Maybe I just don't understand it
acoustic oyster
mmm, ive never much used TDD for a website.
For me test driven dev is is more like: I need to format this data this specific way, so I write tests that can compare the actual output of my code to the output I would expect that code to give me with those predetermined inputs.
I do not work professionally doing this, so someone else may be able to contribute more to this topic.
native tide
hmm, thanks! I'll definitely look into it to wider my understanding
vestal hound
For example, I'm building a website, I just don't see how I can incorporate TDD. What can I write tests on? Maybe I just don't understand it
@native tide how are you building it?

native tide
Flask, sqlite, html css frontend
I guess I could incorporate some testing for APIs that I'll make
vestal hound
I guess I could incorporate some testing for APIs that I'll make
@native tide okay, so minimally you should test your endpoints
the key to testing is understanding the specification of your APIs
preconditions and postconditions, minimally
e.g. say you have a simple API that takes two numbers and divides the first by the second
your preconditions: both inputs must be convertible to int, the second input must not be 0, etc.
write one negative test (input is invalid) for each precondition
same for postconditions
native tide
got it, that's a good start, thank you

400 means bad request.
is the server not logging an exception or something?
i guess it wouldn't be an exception for 400
real island
how do i log the exception
i gave you all the code i had
reading up on it there might be something wrong with the way i am requesting the 'userteam' variable
queen sinew
why are these while loops instead of conditionals?
while loggedIn == True:
global userteam
if request.form['btn_logout'] == 'logout':
loggedIn = False
return render_template("ctf.html", username=username, userteam=userteam)
while loggedIn == False:
return redirect('/')
the both return always on the first loop though
real island
and its still giving the same error
queen sinew
yeah, i didn't think that was the error, just thought it was odd
real island
everything that i read about error 400 in flask says it has something to do with the request.form
but it doesnt seem like there is
<form action="" method="POST">
<input type="text" name="userteam" value="{{ userteam }}" required="true">
<input class="btn" type="submit" value="Login">
</form>
oh shoot i forgot about that
ok so i removed that part
@app.route('/ctf', methods=['GET', 'POST'])
def ctf():
global loggedIn
global userteam
if loggedIn == True:
# if request.form['btn_logout'] == 'logout':
# loggedIn = False
return render_template("ctf.html", username=username, userteam=userteam)
if loggedIn == False:
return redirect('/')
you shouldn't need global if you're just reading the globals
you also don't use them consistently
real island
oh yeah good idea
queen sinew
because you don't have username despite it being a global
did it work now after removing that form check?
real island
nope
queen sinew
silly question but you definitely have a ctf.html in the same directory as login.html?
queen sinew
hmm, how does it know to look in downloadables
queen sinew
so that's not the layout of the code you're running?
real island
currently i am just loading ctf and login
queen sinew
yea but i'm saying you're showing those templates in a subdirectory called downloadable so i wouldn't expect render_template to find them by just the name login.html and ctf.html
oh never mind me
i missed the arrow
haha
real island
lol
queen sinew
what happens if you just return "Logged In" instead of the template
real island
something weird is going on
i did that

@sage thistle sqlalchemy is an orm. it gives you a way to work with databases via objects or query builders over writing strings
different people have different preferences

@native tide start with flask
mellow tide
@native tide Django is a steeper learning curve, but generally more all inclusive, flask is easier, but you need to do a lot of things yourself that you get for free in Django
solar pecan
but if you start with flask, moving to django would be a breeze
mellow tide
That being said, I use neither lol

may as well start with Django if thats your long term goal IMO
solar pecan
and most django developers work in teams since django is for larger websites

@mellow tide I know basics of html and css so can I learn django or Flask?

I take it you know Python
mellow tide
@native tide ok, you need python basics first :)
solar pecan
@native tide okay you are familiar with database integration and python syntax?
if so then you could prolly go to django then
but flask is just simpler if you wanna be web developer, your choice though
native tide
Yes I know python basics and I have built many projects but not related to web development
Are django and Flask backend languages or frameworks like node or react?
mellow tide
@native tide frameworks, although Django is the only one that's a real framework, flask is a micro framework
solar pecan
if you have the willpower then go with django, it'll take some time to get use to but yeah

hi
i'm trying to set up flask_cors to only allow specific origins on a POST endpoint
app.py has
CORS(app, support_credentials=True)
...
route has
...
@cross_origin(origins='foo.com')
...
but i can still make requests with header Origin: bar.com. what am i doing wrong?
do i just not understand CORS? i thought that would mean only requests originating from foo.com would work

else if (document.getElementById(elem).style.backgroundColor === color) {

`document.getElementById(elem).style.backgroundColor = color` it works fine but not with the `if` statements

@native tide what are you trying to do?
there's no CSS because the resources are loaded by path name and not the full URL

OOOO MB
misread it
This is what I used: https://flask-monitoringdashboard.readthedocs.io/en/latest/
This monitors endpoints, and u can configure monitoring to find the lines of code causing congestion
From their Readme: "Profile requests and endpoints: The execution path of every request is tracked and stored into the database. This allows you to gain insight over which functions in your code take the most time to execute. Since all requests for an endpoint are also merged together, the Dashboard provides an overview of which functions are used in which endpoint."

Thinking about getting a vps for web development. It’s 30 bucks a month. Any ideas of what I could expect with this set up?
Not planning anything major, just some portfolio type websites for my friends.
versed python
I don't think 30$ is worth it for a simple portfolio website. If it is a static website, you can use github pages for free. If you really need a vps, vultr.com is a good option. And if you want something specific to django and flask, heroku.com is good (but it might get a bit costly if your website suddenly starts getting massive traffic)
native tide
Linode gives you a terabyte of traffic for $5/mo. I use their cheapest service to run an application deployed to the internet and it performs extremely well
versed python
yep these vps services are pretty cheap if you know where to look. the only downside is you have to configure stuff like ngnix and all yourself, which can be a headache for the first time. paas services like Heroku take care of them for you, but at an increased cost.
gentle ingot
Okay thanks. I don’t expect a lot of traffic even when I redo my own website. Just trying to get experience and make it accessible to show off.
versed python
if your website is static (most portfolio websites are), you should just go with github pages
gentle ingot
For my personal website I plan on having a form. My friends probably will be static though so yeah I probably should lol.
versed python
a simple heroku plan is free. look into that
gentle ingot
Will do.
native tide
One point for Linode- corey schafer (popular python teacher on Youtube) has deployment tutorials for both Flask and Django for them. If you follow them word for word they will work perfectly
but yeah, if you don't want to bother with that, Heroku is good

myobj = {

}
x = requests.get(url, data = myobj)
print(x.text)
x = requests.get(url, data = json.dumps(myobj) )
The .php script tells me, that in order to return results, I need to at least pass some params. It don't seem to transfer the params. I checked the correct names of the values to submit in the url.
Maybe the format of myobs is wrong?
http params ?
the params in this form https://www.kvberlin.de/60arztsuche/suchep.php
try this
'https://www.kvberlin.de/60arztsuche/suchep.php/?param1=value1¶m2=value2'
requests.get only with url then?
https://www.kvberlin.de/60arztsuche/suchep.php/?fachgebietep=Psychologischer Psychotherapeut&Stadtteil=Neukölln
try this. GET doesn't take body of request, only headers
how to execute this in maybe a python script so I can have the result in a local file?

@frozen spear you could use a check before it is allowed to be deleted and on the template. So only if like:
if image.user == user:
# run the code to delete here
and the same in the template, you could do like:
{% if this_image.user == user %}
<div class="delte">
<button>delete</delete>
</div>
{% endif %}
^pseudo code btw

So, what exactly are you using the build your site? Does heroku have some sort of framework to help you, or is it just you writing files?
@worn rapids I just write the files
vsc and then transfer it to github
worn rapids
You should use a web framework (I recommend Flask) to build it. I know it's a bit intimidating, but you have a helpful community here, and it will be rewarding. You need some sort of web framework to make handling requests to your website (like, how you would get from discord.com/register to discord.com/login after registering).
TL;DR: Want to easily add + create + maintain webpages? Use a web framework. Tho anyone out there who's reading this, if u have a easier solution for this guy that would be nice
From my head, an easier solution would be to use Github Pages. You wouldn't need heroku on this route, Github would host it for free (no worries about SSL certification or any of the hosting nitty-gritty). You can still write your own HTML, but Github uses an app called Jekyll to use the HTML templates you wrote and fill in the information dynamically.
You would need to learn how to use Jekyll tho. And my example is here: https://tisuela.com/
And if you don't want to learn HTML, I recommend Weebly as a pretty good website builder, without needing to know HTML or CSS

acoustic oyster
well, we can certainly help you make your website come to life. I do not know how much we can help for a very vague issue like that.
As far as sticky navbar, that is just it! you can google things like that. w3 schools is an amazing resource for things like this https://www.w3schools.com/howto/howto_css_fixed_menu.asp
For a sticky navbar, you pretty much just need to use "position: fixed"
mellow fiber
alright i have made a website in past using HTML and CSS in VS Code @acoustic oyster would you mind looking it i can PM you so you can have an idea about how much I know
acoustic oyster
if you do not have a clear picture of what to do, then I recommend just getting started. Add features you know you need/like. Such as the navbar, then things will hopefully come together. Think about the structure, since it is a very specific website, you could have a home/introduction page, a page with all the real data (like all the facts and in-depth descriptions). Or perhaps you would like to make a new page for each topic

Which framework is good for start?
acoustic oyster
I started with django personally. But I got discouraged the first time because it was very intimidating. After learning more about python I came back and loved it.
I cannot speak to Flask because I never used it. From what I understand flask is easier to get a simple website set up, so it is a more friendly start
static night
Django have nice file structure
acoustic oyster
I found django a great learning experience because of the forced structure. It taught me a lot about how to structure a python project.
I recommend starting with django, but I am biased. You also need to know that you are getting yourself into a more complex framework and be prepared to learn anything you do not understand.
The first time I tried django I did not know what a dictionary was or how to use it, so I got very confused and was already overwhelmed haha.
Corey Schafer on youtube makes it incredibly easy to start with
I believe he also has flask tutorials though

yo is it possible to add 2 models in detailview (django framework)?
@acoustic oyster 😅
acoustic oyster
well hello hello
hmmm, I cannot think of a way off the top of my head. You may need to write a custom view for that, you could possibly inherit from detailview though
wait, a detail view refers to a single view of an object, so I would say no
you would probably need fully custom view for that
lapis spear
well i havent learned custom view yet
acoustic oyster
I mean, you would have to write your own. gimme one sec
lapis spear
yes yes sir😅
acoustic oyster
you would pretty much need to create your own view, im not sure if any of the existing ones would help here.
but a simple version could be
def my_view(request):
context = {
"model1" = model1.objects.all(),
"model2" = model2.objects.all(),
}
return render(request, template_path, context)
so i should just not use class base view for this one?
acoustic oyster
although for a detail view, you may wish to use slugs, or the PK to get the models, rather than getting all
you certainly could, in fact I would recommend it, this was just a simpler way to write out the logic
