[misty dune]

Is there a way that I can pass the java script variable to the html or no?

[native root]

Is there a way? Yes. Is there a reasonably easy way? No

[misty dune]

So could you share with me an example of a fix

[native root]

{{ url_for('buy') }}${fit.name}

You cannot mix jinja and javascript templating without making connections back to your server

What you should do is have url_for return a prefix that would apply to all the stocks, and then simply append to it with javascript

[misty dune]

I don’t understand how to do that

I get what you’re saying that the jinja and ja script won’t work together

But I don’t get how to do what you are proposing

[native root]

You can't pass data from javascript to jinja, but you can pass data from jinja to javascript

Since, at least to me, it appears your urls are like this: http://mysite.com/stock/things/11111

You could request from jinja a url that is not 100% complete, but you could add data on to in your jjavascript code

So, if you do url_for('buy') with no parameters (and that works on your script side), you could expect output of http://mysite.com/stock/things/, and then you could immediately have javascript drop in the ID/name, to make the original url again

[misty dune]

Ooh I see

That’s smart

I’ll try and do that when I get home

I’ll let you know how it goes 🙂

How would I take the last word(JavaScript) as a parameter in the app.py file though

[bleak bobcat]

<a href="{{ url_for('buy') }}${fit.name}">

[misty dune]

@bleak bobcat so how would you be able to access the {fit.name} part in the app.py

Like that code snippet will send the url_for buy with that js var at the end

[bleak bobcat]

You don't. You remove stock_id from your 'buy' url

[misty dune]

And how would I do that?

[bleak bobcat]

Well...I don't know enough about flask, I'm more django oriented, but there must be somewhere you defined a route named 'buy' and also defined that route needs a 'stock_id' parameter ?

[misty dune]

Yep

But I thought to pass a parameter using url_for

You had to give the function url

Followed by a , and then something like stock_id=VALUE

[bleak bobcat]

In jinja yea, but we've already established you can't pass your js variable back to jinja

I don't understand where you're stuck actually because after Bast's explanation you said "I see" ?

[misty dune]

So if i do they code snippet that will do the url for (let’s just say) localhost/buy/stock_id value

That’s what I thought

Is that a wrong assumption?

[bleak bobcat]

Yes

Can you copy/paste your url_for function ?

[misty dune]

What do you mean?

The url_for is just built in

Or do you mean something different

[bleak bobcat]

Ok, show me your routes/urls then

[pale pecan]

@bleak bobcat

ignore the title part

[bleak bobcat]

Why is it another person answering x)

And do you already have a route with only "/buy/" somewhere ?

(if not, create one, it doesn't need to do anything and can even return an empty resonse, or a 404, or whatever you want, you only need it to so you can generate a http://www.domain.com/buy/ url using url_for)

[elder nebula]

Anyone here have experience with google SEO?

[lofty matrix]

If I make a json rest endpoint that does not need to return anything upon success, should I still return an empty dict, or is it fine if it's blank

[distant bobcat]

Anyone recommend a good django video or reading tutorial for beginners?

[wild thunder]

people

please

before i destruct all my home office

i'm like 3 days

trying to END THE FUCKING SCROOLING

in this shit

@distant bobcat Corey is good

https://www.youtube.com/channel/UCCezIgC97PvUuR4_gbFUs5g

[distant bobcat]

Thanks

[wild thunder]

HOW TO stop scrolling

[distant bobcat]

close discord

[wild thunder]

no man, in html + css

[distant bobcat]

ohh

[wild thunder]

my page does be static

always the fucking scroll bars

i tried 100%, 100vw

i'm really pissed

anybody can give me a tip?

i have a div (called #full) this contains the whole page

THIS SHIT IS ALWAYS getting scrollbars

there is any way i can make it stop w

?

shit, i hate this

[echo dawn]

are you trying to hide the scroll bars? or just get rid of them altogether

@wild thunder

[wild thunder]

get rid of them

for life

i'm really pissed

this fucked my afternoon

i'm fully stressed

[echo dawn]

you're fine

did you try the overflow command with css?

[wild thunder]

yes

but not in the entire page

just in inside elements

i made some styles that makes that shit not visible

it just scrolls

but i dont want my "fullscreen" to scroll

elements can scroll

not header nor footer

just body elements

[echo dawn]

like, is everything scrolling on its own? or am i just massively misunderstanding...

[wild thunder]

imagine you are on a page

[echo dawn]

ok

[wild thunder]

it's static right?

my page was supposed to be static too

the full page

like "width 100% and height 100%"

fullscreen - no scrolling

i can do this one time

when i start modeling inside elements

this shit began to appear again

my page start to have horizontal scrools

[echo dawn]

are you using inline styling or a separate stylesheet

[wild thunder]

an separated .css file

importing it via normal ways

[cerulean vapor]

Start with the outermost element and reintroduce the others one by one

when you get your scrollbars, that's a sign which element is the issue

[wild thunder]

yes, i got that, but i'm using % for all my inside elements

it should not behave that way, right w

?

i re-read my code at least 20 times

this shit is ok

[bleak bobcat]

Be careful of margins and paddings if you don't have border-box on your elements

(Also default browser's margins)

[cerulean vapor]

@bleak bobcat beat me to it

[wild thunder]

idk if the problem is my tv

i'm using my Sony 40" as monitor

[frosty nymph]

did you do this?

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

[cerulean vapor]

That shouldn't matter

[bleak bobcat]

Doesn't matter

can you https://ngrok.com/ your code ?

[wild thunder]

@frosty nymph i'll add that "box-sizing"

well, i think it's getting somewhere now

it worked

[frosty nymph]

cool

[bleak bobcat]

So it was a padding on one of your elements

[wild thunder]

i had made this interface already, it was ok

then i'm using flask

idk why, but some stuff got out of align

[bleak bobcat]

Has nothing to do with flask, we're only talking html & css here

[wild thunder]

and when i tried to fix, got worse

i'm re-doing

the page

and got this problem

i almost throw my tv at the wall

3 hours for a shitty problem

damn scrolling, i hate this

sorry for all this hate

i really lost my temper

thanks for helping guys

this channel rocks

[bleak bobcat]

It's fine, people who don't understand how css works usually hate css :p

[wild thunder]

yes

i'm 4 months programming

started with python

for django

but it needs html and css

then i went to it

i made a homepage + login scren + user interface

[bleak bobcat]

Are you using any css framework ?

[wild thunder]

now, left django, started flask

@bleak bobcat no, which kind of frameworks are out there?

idk it has frameworks lol

[bleak bobcat]

The most famous and used one is https://getbootstrap.com/

[wild thunder]

and sorry my mispelling/word order, english is not my native language

[cerulean vapor]

I heart Bootstrap

[wild thunder]

can you list the 3 main reasons bootstrap is useful? i'm new to all of this

[cerulean vapor]

It saves you from having to reinvent the wheel when creating many common interfaces

I'm working on a personal wiki app that uses BS templates

it's a massive timesvaer

[bleak bobcat]

Basically you could build a whole, nice looking website, without writing a single line of css

IT gives you lots of classes to style/layout your elements

[cerulean vapor]

You can modify the results later with your own custom CSS, as you get experienced

but you can just drop it in as-is and go

[wild thunder]

shit, this is cool

it would spare me at least 15 days

i'm looking at templates

[cerulean vapor]

THis is what the UI looks right now

BS4 saved me tons of trouble

(that page is for a book I'm working on; the wiki is mainly to let me organize my writing projects)

[echo dawn]

@wild thunder don't get the wrong version. the first time i tried bootstrap, i almost broke my computer. it made me write about 30 <div> tags with separate id attributes and i wanted to scream. apparently theres other spoof versions of bootstrap?

[wild thunder]

man you give all this roundabout to be working on a book at the same time

you are my hero now

[bleak bobcat]

There's also https://foundation.zurb.com/ https://materializecss.com/ and https://bulma.io/ which are pretty nice (only use one though, there's no point combining those)

[wild thunder]

@echo dawn i'm fully stressed, i guess i'll continue tomorrow

[cerulean vapor]

@wild thunder I was using another wiki app but it wasn't very good, so I decided to write my own

[wild thunder]

guys, let's make it simple, if i pass what i want to make, can you tell me whats best choice?

i don't want to be a front-end specialist, i preffer back end stuff

if i can make my interfaces cool enough i'm happy

@cerulean vapor definetely you are my hero

[cerulean vapor]

BS4 is easy enough to get going with - they have tons of examples you can just boost as-is for many common applications

GTG, BBL

[distant bobcat]

can I jump into django with very little html experience?

[bleak bobcat]

@wild thunder I know a ton of back-end developers who don't know much about html & css but still manage to build ok looking website just because they took the time to learn how to use bootstrap

[wild thunder]

i read the word "bootstrap" many times while studying css

but never looked for

all this problem started when i tried to "centralize" my text vertically

it was aligned to top (default) but my text did not align

[last bobcat]

I have a small web app I wanna make. Typically a C# dev but I’m wanting to use python. What frameworks should I be looking into it? I’ve seen flask and Django mentioned. Is flask only server side api? Meaning no front end component?

[quasi ridge]

I guess you'd call it server side ...

I mean you can use it to serve js

I don't know what frameworks do include a front-end component

[last bobcat]

Everything I’ve read says Django supports front end

It’s a full stack framework apparently

I don’t need much of a front end. Just a few text boxes. Super simple

[cobalt atlas]

ok so i am making a app that will take a spotify playlist and do some stuff with it(already made this python script), but i want to combine this script with a nodejs server. What is the best way I could do that?(I already tried python shell and i spent like 3 hours trying to get it to work then i gave up) Thank you for the responses

[vagrant adder]

@last bobcat you can make full-on websites with both django and flask

They both have templating engine integrated

[blazing compass]

hey i know how to make django blog but i want to implement google maps in to find nearby shelter for night if possible pls tell me how to proceed ahead?

[meager barn]

is this normal? chrome renders colors very differently

on chrome

on ff

like miles away different

rgb(24,24,255)

should look like on the ff

[native root]

No, that is not normal

also that rgba() call is wrong, rgba requires four values: r, g, b, and alpha (which goes from 0-1 unlike alll the others)

[meager barn]

srry, its only rgb

ill just try to reinstall chrome see if that works

[winter flint]

I have a flask app (a discussion forum) that is dockerized and hosted on digital ocean. Users can upload avatars and stuff that currently get placed in the 'static' folder in the app. The problem is, since it's a docker image, if I update the app on my local machine and want to replace the old docker image with a new one, that static folder is overwritten. What's the best way to solve this? Store user uploads outside of the docker image? Download the contents of the folder to my local machine before re-imaging?

[vagrant adder]

you might take look at amazon s3 bucket or dropbox

and you can save your avatars there

there are apis for accessing both dropbox and amazon s3 instances

[winter flint]

that's a good idea

[gilded monolith]

Does docker volumes could also be something to consider here ? (I do not know, i ask to see if i understand it)

[winter flint]

I think that would work as well, yes

[vagrant adder]

yes it could

[native tide]

hi

i want to add a functionality

when i click a certain button an area of my webpage translates to the language i want

i've tried it with JS

here

    var briefAbout = getElementById('brief-about');
    function translate_to_english(){
        return briefAbout.innerHTML = `This website was created by me(Kenny Hoft).
        I am a middle school student who creates website just for fun.
        So it's my Hobby. But this website was created to put my summary on it from the books i read for school.
        And i created it so i can hone my web development skills.
        I also put the names of the people of my group here so they can write their summaries too.
        This website was possible because my teacher allowed it that i made a website to put my summary on it for her to read, so thanks to her.
        Enjoy reading!`;
    }
    function translate_to_dutch(){
        briefAbout.innerHTML = `Deze website is gemaakt door mij (Kenny Hoft).
        Ik ben een middelbare scholier die een website maakt voor de lol.
        Dus het is mijn hobby. Maar deze website is gemaakt om mijn samenvatting erop te zetten uit de boeken die ik voor school heb gelezen.
        En ik heb het gemaakt zodat ik mijn vaardigheden voor webontwikkeling kan verbeteren.
        Ik heb hier ook de namen van de mensen van mijn groep geplaatst, zodat zij ook hun samenvattingen kunnen schrijven.

        Veel plezier met lezen!`;
    }
    
</script>```

i added an onclick event

                                <button onclick="translate_to_english()">English</button>
                                <button onclick="translate_to_dutch()">Dutch</button>
                            </div>```

i don't know what i am doing wrong here

i am a beginner at JavaScript so yeah

need some help here

[jovial portal]

I have a question

how would I get all the links that a website has

Example:

• https://example.com/login.php

• https://example.com/logout.php

etc..

nvm think I've figured it out

[dense hound]

@native tide make sure your Javscript file is imported at the very end of body, see: https://www.w3schools.com/js/tryit.asp?filename=tryjs_whereto_external

@jovial portal Sitemaps / Custom scrapers.

[high garnet]

https://milddev.com/flask/create-a-simple-rest-api-in-python-using-flask/

[native tide]

@dense hound it still doesn't work

[vagrant adder]

@native tide you have to link your js file in your html

[native tide]

But it doesn't matter if i do it internal right?

[native tide]

i put the script tag in the same file where the page template is @vagrant adder

[vagrant adder]

Put it in static folder so you can link it properly

Then link it in html via script tag and url_for in src attribute

I can help you when i get home

[native tide]

I'm trying to remove borders from my input boxes with CSS. I've applied the border: none;, everything gets removed but this top part

What the hell do I do

[rigid laurel]

box-shadow: none;?

[native tide]

Wow ok i hate myself

thanks

[rigid laurel]

I'm guessing its a framework that added the shadow - thats why I find using bootstrap or similar very frustrating

[native tide]

It's a project that got literally tossed to me and I have to do the frontend for it

[native tide]

how would i implement a webserver in python the dynamically adds data to the webpage without having to reload the whole page? i am getting the data from a client via sockets. can someone link me a project where i can learn it from? any ideas?

[rigid laurel]

You would need JavaScript to do that

[hoary spruce]

Kind of on the same topic, i'm trying to accomplish something similar. With refreshing the page automaticly with new records from a DB. And I found this example: https://stackoverflow.com/a/46719768

but I'm using a Mysql DB, how would I do the same with those records I pull then?

[native tide]

i already can update the entire html document with javascript every x second by inserting window.location.reload(true); into the html but i liked to reload when my python scripts decides to reload

@rigid laurel

[native tide]

Ok saki

[rigid laurel]

First of all, thats quite a bad way of updating the page. Second of all, in that case you could poll a python endpoint until the endpoint tells you the page has updated, then reload the whole page

so you'd need to make a small python api in something like Flask

[vagrant adder]

@native tide oof i'm not home anymore

[native tide]

Oh

Ok

[iron sinew]

I'm using the glitch webserver (glitch.com) and for some reason this is returning an error

Is this because of python 2? Anyone know how to update it?

[quasi ridge]

that's python3 code, and you're using python2 to run it

see if you can run it with python3

[iron sinew]

that's what I don't get

I don't see anywhere where it says python2

actually, the source demo I copied this from says it's python 3 lol

it uses gunicorn whatever that means

[quasi ridge]

why would it say "python2" if it's python3?

How are you running it?

"gunicorn" is a decent web server written in python

[iron sinew]

there's a start.sh

[quasi ridge]

look inside it.

[iron sinew]

with python server.py

[quasi ridge]

there's your problem.

[iron sinew]

🤔

[quasi ridge]

your system's "python" is almost certainly python2

that's odd, though, that they did that; since the code clearly requires python3, I'd have expected start.sh to say python3

was the start.sh written by the same person who wrote the rest of the stuff?

[iron sinew]

Yeah

Well, I just copied an example

[quasi ridge]

odder still

oh.

[iron sinew]

and put my own stuff in

so yeah

[quasi ridge]

there ya go

[iron sinew]

The code is mine

[quasi ridge]

so fix it

[iron sinew]

oh hey

its working now

but its still not printing to the console

even im using file=sys.stderr

[quasi ridge]

the output might have wound up in a log file

that often happens with web servers

[iron sinew]

I dont see a log file

[quasi ridge]

it could be anywhere

[iron sinew]

I'm looking in the files right here

assets is just a bunch of random pictures

oh wait

for some reason you have to visit the page for it to start logging

why is that?

[quasi ridge]

probably "laziness" -- it doesn't have anything to say until you visit a page

[iron sinew]

is there a way to bypass this

[quasi ridge]

you can "raise" the "logging level", that might help.

You'll get a few messages as soon as you start up, saying stuff like "Hi, gunicorn here; I'm running three threads and my process ID is 12345" and stuff

there's probably a gunicorn.conf somewhere that defines the logging level(s)

[iron sinew]

I don't see one

all the files I have are the ones shown above

[quasi ridge]

five files total?

that's not many files for a whole web server

I'd be surprised if gunicorn can even run without some sort of conf file

[iron sinew]

idk what im doing here lol

[quasi ridge]

you're learning how to run a little web server

[iron sinew]

oh

neat

[iron sinew]

I'm trying to get the server.py file to write to a log.txt

logMsg = "On program load at " + formattedTime + ", " + setCommas(list(newAddition)) + " were online"
with open("log.txt", "a") as logFile:
    logFile.write(logMsg + "\n")```

This isn't doing it

[iron sinew]

Please ping me

[quasi ridge]

@iron sinew why do you say it's not doing it? What are you observing that differs from what you expected to observe?

[iron sinew]

It's not writing it to the file

But it should be

[quasi ridge]

how do you know it's not?

(Btw, what you've got there looks reasonable)

[iron sinew]

The file has nothing in it

[quasi ridge]

is that code that you pasted above complete?

'cuz I'm running that code, and it works for me

[iron sinew]

Yeah

it's still on the glitch.com webserver btw

but it's in the same dir

[quasi ridge]

my guesses:

• you have two files named log.txt, and you're looking in the wrong one
• you have a bunch more code inside that with, and the file isn't getting closed before you look in it

[iron sinew]

That's all that is in the with block

[quasi ridge]

ok, what's the working directory of the python process?

ooh another guess:

• the open or the write are failing with an exception, but for some reason, you don't see that exception

[iron sinew]

Oh

I didn't set one

[quasi ridge]

well you don't need to set it, but it'd be good to know what it is, so you can, for example, figure out where your log files go 🙂

perhaps print it out!

perhaps use an absolute file name instead of log.txt

[iron sinew]

How do I get the current working OS?

I imagine I'll need the os module

[quasi ridge]

os.getcwd yeah

[iron sinew]

and now it's not printing

reeee

[quasi ridge]

your stdout and/or stderr are probaby going to other log files.

we talked about that earlier

[iron sinew]

that works fine

when I put it before the app.run

but afterwards it just doesnt run

[quasi ridge]

sorry I don't know what app.run is

[iron sinew]

it runs the main() method

[quasi ridge]

if you think some code isn't being executed, stick 5/0 in there -- if that does get executed, you're pretty likely to notice the divide-by-zero error

[iron sinew]

no error

🤔

[quasi ridge]

ok that should tell you something

[iron sinew]

idk what im doing wrong tho

no syntax errors

it worked before

[quasi ridge]

another option, if you think the code is being executed, but it's too hard to find the files to which stdout is being redirected -- have your prints go to some file whose location you know. For example: ```py
logMsg = "On program load at " + ", " + " were online"
with open("log.txt", "a") as logFile:
with open("/tmp/another-log-file", "w") as damn_it:
logFile.write(logMsg + "\n")
print(f"Wrote that log message to {logFile}", file=damn_it)

[iron sinew]

Should I put a /log.txt

to start in the root directory

this server is confusing

[quasi ridge]

you probably don't have write access to that directory

[iron sinew]

because it shouldnt support python

but it supports html

[quasi ridge]

/tmp is better

[iron sinew]

k

it should create the file if it isnt real too, yeah?

[quasi ridge]

no idea what you mean by "this server ... shouldn't support python, but it supports html".

yes, open as I wrote it will create the file if it doesn't exist (and will overwrite it if it does). Note that I removed one of the two / in the file name

[iron sinew]

cwd is /app

so /app/log.txt

[quasi ridge]

do you have permission to create files there?

I know you had an empty log.txt there once, but I don't know how it got there

[iron sinew]

I created it

I could invite you to the codebase if u want

so u can see it live

[quasi ridge]

I'll take a look, but there's only maybe a 30% chance I'll be able to get it running

[iron sinew]

dmed

dmed

[quasi ridge]

wow that is a small project! 🙂

ok gimme a while

[iron sinew]

xd

[quasi ridge]

OK I hit the 5/0 as soon as I pointed my browser at http://127.0.0.1:5000/

you say you didn't see that?

[iron sinew]

I thought it means projecturl:5000

cuz thats how I started it before

i didnt know it hosted it on my machine

oh did u copy the code onto ur machine

[quasi ridge]

I don't know what you mean by "I thought it means ..."

yes, I copied the code onto my machine

[iron sinew]

Ah

So to turn it on

[quasi ridge]

I don't know how to use glitch

[iron sinew]

I'd need to access https://mc-player-logger.glitch.me:5000

[quasi ridge]

so you're running this code on someone else's server (namely: the "glitch" people). It's possible that that server does crazy stuff, like throw away anything you write to a file; I don't know

[iron sinew]

dang

If I could figure out how to save the console output

that'd work too

[quasi ridge]

I don't think that's likely, but it's possible

[iron sinew]

ill ask the support ppl

[quasi ridge]

well you could shove all that output into the response

[iron sinew]

what it returns?

[quasi ridge]

yeah

pretty sure you don't want your / route to loop forever

that means the person hitting your server will have to wait literally forever for the page to load

web servers need to return responses quickly

[iron sinew]

It wasn't designed to be accessable

I'm literally only using flask because it doesn't support python, but it does support html, and you can run flask on the html basis?

idk how the whole thing works

[quasi ridge]

also I don't see you generating a response anywhere

OK I gotta admit: "I'm literally only using flask because it doesn't support python, but it does support html, and you can run flask on the html basis?" makes exactly zero sense

flask is for writing webservers, and only for writing web servers.

If you don't want to write a web server, don't use flask. Simple.

Do you want to write a web server? I literally can't tell.

[iron sinew]

I just want to host this python project online

so it can run when my PC isn't on

[quasi ridge]

so this is something that runs all the time, and does ... something?

[iron sinew]

Yeah

[quasi ridge]

What is it supposed to do?

[iron sinew]

Log players on a minecraft server

[quasi ridge]

Like, if it were to suddenly stop working, who would notice, and how would they notice?

it looks like it's collecting a little bit of data about Minecraft, and then ... not doing anything with it

[iron sinew]

I want it to store it in the file

[quasi ridge]

what does "Log" mean here?

[iron sinew]

but it's not

and idk why

[quasi ridge]

ok, so you want it to write stuff into a file. Who will read this file? When? How?

[iron sinew]

Me

Every day-ish

but going into the project files and clicking on the log.txt

[quasi ridge]

ok, so hosting it on glitch might make sense. Using flask, however, doesn't

unless you already know how to write a web server (or are happy to learn)

this is something I would probably do with an EC2 instance, but that's just me

(or linode or whatever)

[iron sinew]

EC2?

[quasi ridge]

EC2, yes.

do you not know what that is? It's basically "rent a Linux computer in the cloud"

[iron sinew]

I have no way to pay for any of that tho

I don't have a credit card

Do they have a free tier or something?

[quasi ridge]

they do; I don't know how many zorkmids you get for free, though

[iron sinew]

zorkmids

huh

[quasi ridge]

I'd have said "mojo" but that doesn't come in discrete units 🙂

anyway you certainly can make a web app to do this. But you should check that files on glitch work the way you'd expect; as I said, it's possible they're doing something odd

bugbounty?

@storm schooner

[storm schooner]

google it

[marble pulsar]

and what's the purpose of posting that here?

[native tide]

i can't post my website online

[marble pulsar]

and what does "Hacking Twitter for $$" has to do with that. Why did he post that

[native tide]

don't know

can you help me?

please

[marble pulsar]

idk the question. Ask

[native tide]

ok

how can i set the html code i have online so that people can see the website

if they know the url

@marble pulsar

[marble pulsar]

so

you have html website and you want to host it or?

[native tide]

yes

@marble pulsar

[marble pulsar]

use any free webhost and just rename the html file to index.html and upload to webhost

you can even use github for that

look up https://pages.github.com/

or you can use other hosts

[native tide]

is it as www.###.com

?

[marble pulsar]

no you have to buy your own domain and set it up

they just provide the hosting

[native tide]

ok

is www.###.github.com possible?

@marble pulsar

[shadow hornet]

it's your_username.github.io

[marble pulsar]

you will get github.io I think

[shadow hornet]

you don't get www.

example: https://den4200.github.io/

[native tide]

ok

will that be as i want to the code?

ok thank you

will github set it online for me?

[shadow hornet]

all you need to do is push your code to your repo and it'll be up in a few minutes

[native tide]

ok thank you

now?

@shadow hornet

[shadow hornet]

that's not how it works

[native tide]

how to do it then?

[shadow hornet]

you have to use your github username

[native tide]

in the url or?

or where?

[shadow hornet]

so in your case, Dart2004.github.io

[native tide]

ok thank you

[shadow hornet]

example ^

np

[native tide]

oh so

so?

@shadow hornet

[shadow hornet]

yes except you don't have an index.html

[native tide]

it is on .github/workflows

isn't that working?

@shadow hornet

not working i tried no website

[shadow hornet]

you'll have to wait a few minutes as i said earlier

[native tide]

ok

[shadow hornet]

it doesn't come up instantly

[native tide]

can you look at it then too?

[shadow hornet]

ah i think the repo name has to be all lowercase

not 100% on that though

nvm it doesn't

just wait a few minutes

[native tide]

ok thank you

[shadow hornet]

i just realized

you have that repository private

that's not going to work, unless you upgrade to pro

@native tide

[native tide]

to public?

[shadow hornet]

yeah

[native tide]

ok

thank you

how to add a new folder?

@shadow hornet

[shadow hornet]

wdym?

[native tide]

a new folder to the repository

[shadow hornet]

ah make a folderlike you normally would, commit, and push?

[native tide]

yes

i must go off see you later ok?

[shadow hornet]

alright

[native tide]

i will tell you per ping ok?

[shadow hornet]

sure i'll respond if i'm around

[native tide]

ok thank you

I know I'm targeting the right class since if I try changing the font, it changes. I want to make it when you hover over the text the colour changes to red. I have the exact same class, just on the different side of the navbar and it works

Um what. If I press the button the colour changes to red?

[lucid night]

Hey guys, I have architecture related question
I would like to ask you about following scenario: I have bunch of Scrapy scrappers which after scraping also processes data and eventually saves it to database.
The second logical component is simple django application for displaying data.
The problem I see is that scrappers uses models from django which doesnt follow separation of concerns in my opinion.
The other pain with current solution is those crawling things are executed on webserver - I know it should be using Celery tasks.
But if I would separate scrapy logic from django then I could run it serverless and pay even less?
I know that drawback would be to set up the same model for scrapy and each change in it would require to adjust code in second component.
What do you think about that, how would you solve it? Is it ok for you to have scrappers inside django application?

[vagrant adder]

you can make an api

so when scrapers do the job, they don't interact with the database through models

they can make a post request to the api and api deals with the models and database

[lucid night]

Yeah, this is some idea but with hundreds of such requests I could make self harakiri to it 😅

[vagrant adder]

i think it could be the only way

[bleak osprey]

You are most likely running forms.py in a different environment. Close the terminal and restart with the correct environment.

If you are using Visual Studio, just delete the venv and start afresh with a new one,

and use the requirements.txt to make installation faster

mm i'm using it in this

it's the same of the windows shell

but if i write py -3 -m venv venv it tells me this

I've set the header as Accept-Encoding with values as gzip and deflate

But it's still showing the weird encryption

Any ideas? 😄

[vagrant adder]

because its gzipped

you need to unzip the download file

here there is no problem

probably, in the others I have to remove them, even if it is strange, since the tutorial shows it as I did

Hello

can anyone tell me how to delete a file that is held in a WTF filefield ()

Can you explain more

[tranquil robin]

Hey there,
I am currently working on CS50W project1 where I am supposed to create a website using (Python, FLask, SQLAlchemy) but I am not allowed to use ORM (so all SQL queries should be performed using SQL commands "using .execute(" SQL COMMAND HERE ")" )

so i am trying to make classes that will have methods that perform the commands i need
in the search method I am getting a None result and I dont understand why.
see code below

from libreria import db


class User():

    def __init__(self, username, password):
        self.username = username
        self.password = password
        self.id = id

    def create(self):
        username = self.username
        password = self.password
        db.session.execute("INSERT INTO users (username, password) VALUES (:username, :password)", {"username": self.username, "password": self.password})
        db.session.commit()

    def search(self):
        temp = db.session.execute("SELECT username,password FROM users WHERE username = :username", {"username":self.username, "password":self.password}).fetchone()
        db.session.commit()
        print(temp)

tempuser = User("username1","password1")
print(tempuser.search())

the result is of the print is:

('username1', 'password1')
None

why is there None there?

[vagrant adder]

So this is the function thing

So see, there is a print function in the search function

But the function isn't returning anything, there is no return statement

[tranquil robin]

aah

so if i return "temp" then i will get the info without the None?

[vagrant adder]

So when you do print(user.search()), print() within gets triggered and return value of the function gets printed

Yes, return temp

[tranquil robin]

and i do not need to use db.session.commit() when executing a SELECT query right?

[vagrant adder]

I don't know about that

I think you need

Never used db.session.execute() myself

[tranquil robin]

oki

thanks a lot m8 🙂

[vagrant adder]

Quick tip: remove print statement in function when going to production

[tranquil robin]

yeah already did, was just to know what the contents where, thanks 😄

not being allowed to use ORM was such a pain 😛

been at it for 2 days now

but its finally working 😄 😄

For some reason my ```css
@media screen and (max-width: 768px){
.header{
display: flex;
justify-content: flex-end;
width: 100%;
}
.container{
position: fixed;
width: 25%;
background-color: blue;
}

}

is being overridden by 
```css
  .container{
        display:flex;
        list-style: none;
        width: 75%;
        height: 100%;
        justify-content: space-around;
        align-items: center;
    }
    .header{
        width: 75%;
        display: flex;
        justify-content: flex-end;
    }

when the screen is below the given width. But only some parts. The background does set itself to blue, but the width does not apply

i'm writing aiohttp app behind nginx, I want to be able to generate temporary urls to files, but don't want aiohttp to send them, nginx should do this.
How could I do it? Here's the algo:

• user: requests file real_file.txt from HTML page
• frontend: sends request to server to generate temp access token
• aiohttp backend: generates and returns temp access token 1234
• user: makes request to /real_file.txt?access_token=1234 url
• aiohttp backend: validates access_token and returns 302 redirect to X/real_file.txt if valid
• nginx: catches 302 and returns file from X/real_file.txt

I found this SO answer about catching 302 redirect internally: https://stackoverflow.com/questions/20254456/intercepting-backend-301-302-redirects-proxy-pass-and-rewriting-to-another-loc

I'm not sure what X url from this algo should be, could it be just

location /random_path {
  root /media;
}``` ?
In this case this path can be bruteforced and I would need to change `X` in both backend and nginx

Is this an optimal solution overall?

two different sites that are in the same VPS can operate on the same database?

[vagrant adder]

yes

i don't know how are you having 2 websites running on same vps, but yes databases usually allow for more connections

[cloud path]

mm ok ok well, and can each use a different type of database manager? for example, the one Mysql and the other sqlite, for the same database?

[vagrant adder]

well, mysql and sqlite are 2 different databases, not dbms-es

your database can be sqlite and mysql

it's the orm/library that allows for db interacting that can be different

[cloud path]

ah ok, thanks for the support man

i understand

hey there,
I am currently trying to use flask-login with a custom user class to login my users.
but I am getting an error.
this is the user class and login decorator part

from libreria import db, login_manager
from flask_login import UserMixin


@login_manager.user_loader
def load_user(user_id):
    return User.searchwo(id=user_id)

class User(UserMixin):

    def __init__(self, username, password=None, id=None):
        self.username = username
        self.password = password
        self.id = id

    def create(self):
        db.session.execute("INSERT INTO users (username, password) VALUES (:username, :password)", {"username": self.username, "password": self.password})
        db.session.commit()

    def search(self):
        response = db.session.execute("SELECT id,username,password FROM users WHERE username = :username", {"username":self.username}).fetchone()
        if response != None:
            self.id = response[0]
            self.password = response[2]
        return response

    @staticmethod
    def searchwo(id=None, username=None):
        if id is not None:
            response = db.session.execute("SELECT id,username,password FROM users WHERE id = :id", {"id":id}).fetchone()
        elif username is not None:
            response = db.session.execute("SELECT id,username,password FROM users WHERE username = :username", {"username":username}).fetchone()
        return response

when I try to login on my website I get the following error

sqlalchemy.exc.DataError: (psycopg2.errors.InvalidTextRepresentation) invalid input syntax for integer: "None"
LINE 1: SELECT id,username,password FROM users WHERE id = 'None'
                                                          ^

[SQL: SELECT id,username,password FROM users WHERE id = %(id)s]
[parameters: {'id': 'None'}]
(Background on this error at: http://sqlalche.me/e/9h9h)

any ideas?

so there is probably something wrong with the user_id being set to None, but I don't really understand the when and where the load_user() is being called so I dont know if the id is defined at the time and place

[bleak bobcat]

Are you sure it's set to None and not 'None' (string) ?

[tranquil robin]

yeah

i changed it from id to username, and now the website works

but i dont understand why, and I dont understand when this "user_loader" is being called

because in my login route i set the ID of the user, that i get from the DB

hey guys just a lil question with flask

in the paramters of app.route(), is it possible to add a second paramter after that /<name>

[vagrant adder]

of course

[inner stump]

wait really

[vagrant adder]

yes

[inner stump]

how

[vagrant adder]

can you paste your code from the screenshot?

[inner stump]

`@app.route("/<name>")
def home(name):
return render_template("index.html", content = name, title = "Hello")

if name == "main":
app.run()
`

[vagrant adder]

@app.route("/<name>/<surname>")
def home(name, surname):
    return render_template("index.html", full_name=(name, surname), title="Hello")

if __name__ == "__main__":
    app.run()

this should work

[inner stump]

i think i just broke it

@app.route("/home") @app.route("/<name>/<lastname>") def home(name, lastname): return render_template("index.html", full_name(name, lastname), title = "Hello")

am I allowed to put 2 of @native vessel.route

saki can you pls help

[vagrant adder]

you can add more route pointers if they have same arguments

you can't do

@app.route("/")
@app.route("/name/<name>")

but you can do

@app.route("/<name>")
@app.route("/name/<name>")

what you are trying to acomplish is simply not possible

[inner stump]

what is tis

would this fix like the Url not found issue

[vagrant adder]

you mean 404 error?

[inner stump]

it changed to this

[vagrant adder]

now that's on you

html issue

anyhow, gonna sleep

[inner stump]

I dont think there's a mistake here

ah ok thank you for helping gn

[vagrant adder]

[tranquil robin]

@inner stump there is a space after the % in {% endblock% } dont know if that will cause an error or not though

omg it worked

I don't wanna complain but this thing is a bit extra

but thank you bro

[lean birch]

idk if this is the right spot for this, but im trying to send a POST request to a certain website, and the response is either 403 or 406. ive been messing with the headers for about an hour and I have no idea what to do. any pointers anybody?

[quasi ridge]

do you know what those responses mean? I don't, without looking them up

[lean birch]

403 is forbidden, 406 is non acceptable

I get 406 more

I read it has to do with the “Accept” header, which ive played with over and over, no progress

ive done a lot with these types of projects, and ive never seen 406 this much. the site doesnt require proxies or anything either.

[quasi ridge]

well I can't tell without knowing a lot about the web site, unfortunately. They're free to return any response they want for any reason they want.

[lean birch]

what would you suggest i do to become more knowledgeable about the site then?

maybe im missing something about it, seemed pretty simple going into it

[native root]

this is a good example/method as well:

@app.route('/users/', defaults={'page': 1})
@app.route('/users/page/<int:page>')
def show_users(page):
    pass

@inner stump

[quasi ridge]

@lean birch I can't suggest anything you wouldn't think of on your own -- read their API docs, if they have any; use the "developer tools" in your browser to see what a successful request looks like ...

[dusk bane]

Does anyone have experience with redis queue?

[quasi ridge]

don't ask in a zillion channels

[lean birch]

they block dev tools on a successful submission

[quasi ridge]

maybe you need to spoof the User-Agent header

i.e., lie to them and say you're using Chrome instead of requests

[lean birch]

ive been using a chrome User-Agent

Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.117 Safari/537.36 to be exact

requests would show python-requests or something with no header user agent selected, and no site likes to accept anything from that

[quasi ridge]

well, some sites reject that

[lean birch]

stupid sites

but also, when i sign up through chrome with that User-Agent, it succeeds

im so lost LMAO

[quasi ridge]

use the browser's developer tools to examine the requests, so that you can duplicate them

[vagrant adder]

@inner stump its really bad practise to do two functions on one route

[tranquil robin]

@vagrant adder why is it a bad practice to have two functions on one route?

[vagrant adder]

Because the code will get dirty very quickly

[tranquil robin]

dirty as in complex?

[vagrant adder]

Yes

[tranquil robin]

oki great,
Another quick question, is there a way using (python, flask and html - no JS or anything else) to get the following:
click a button, send me to a route, and after a couple of seconds, send me to another route
so (I am in home.html, i click logout, i go to logout.html, the after lets say 5 seconds, I go to login.html)

[vagrant adder]

Nope

You'd need some js for waiting and redirecting

[tranquil robin]

aha, well too bad I guess 😄 , the user will have to just logout without any eye candy 😛

[vagrant adder]

You aren't allowed to do any js?

[tranquil robin]

nah, I don't know any JS, its the next chapter in the course

so I am expecting that applying it will take time as I know nothing about it

if its easy and you could guide me, then great. If not then no user eye candy 🤣

[vagrant adder]

I know some basics like creating stuff onclick, redirecting and shit

I can show you what i knoe

[tranquil robin]

what I want is something very simple, it goes like this

I am on any of my routes (main, books, reviews...etc) and the user clicks "Logout"

I then want to go to (Logout.html) which has a fancy goodbye message, the he gets redirected to (/login) again

he stays in logout.html for like 3 to 5 seconds

[vagrant adder]

I am not home rn, i can show you a when i get

[tranquil robin]

sure nps, will hopefully get the rest of the site ready by then 😄

surely you don't need to know PHP if you know python and django.

HTML and CSS would be useful

[polar flume]

@quasi ridge what about js?

[quasi ridge]

quite useful

so you know: PHP is an alternative to python and django. (And it's a really terrible one, too; I wouldn't work for a company that proudly uses PHP)

[polar flume]

Thanks

guys how can one make PWA on django ?? i learnt about service workers and web manifest but since django is MVC framework, how can one structure the projects so that it can be used as PWA. ??

[quasi ridge]

no idea what PWA is, sorry

[rancid rose]

Progressive Web App

[quasi ridge]

well, now I know what the letters stand for; but I don't know what those words mean. You probably want someone else to help you

[balmy forge]

You can do it with something like django-progressive-web-app - like this one https://github.com/svvitale/django-progressive-web-app

Basically you will need a serviceworker.js

And then you can inject it

I found a medium post that's very informative about it as well, you can read about it here - https://medium.com/beginners-guide-to-mobile-web-development/convert-django-website-to-a-progressive-web-app-3536bc4f2862

I'm making REST HTTP json API, I have a /nicknames/check endpoint used to check if nickname is used or not, what status codes should it return?
Possible cases are:

1. nickname aready taken - 200?
2. nickname is not taken - 404?
3. nickname has invalid format - 400?

[brittle cradle]

OK cool @tranquil robin , I've got this code which works for filtering the Total_Scheduled values I want:

for (var i = 0; i < source.get_length(); i++){
    if (source.data['Total_Scheduled'][i] >= SchedSlider.value[0]
        &&
       source.data['Total_Scheduled'][i] <= SchedSlider.value[1]
    ){
        indices.push(true);
    } else {indices.push(false);}}return indices;
''')```

But the thing is that I want to expand this to also include filtering for another variable, but of a category (not a number)

Hello. I just started out with Django a few days ago and I'm struggling with implementing the login page properly. I'm using the default LoginView (from django.contrib.auth import views as auth_views). How can I customize this view so that it will accept a 'title' variable for the page?This page is an extension of a base.html page, where I've added the proper conditions to accept a title passed in the view. Thank you!

[brittle cradle]

I found this JS code from a stackoverflow response, which worked well by itself, but I don't know how to adapt and integrate it into the code above. Pycharm doesn't show what might be wrong as it's all in quotes... :

let selected = checkbox_group.active.map(i=>checkbox_group.labels[i]);
let indices = [];
let column = source.data.species;
for(let i=0; i<column.length; i++){
    if(selected.includes(column[i])){
        indices.push(i);
    }
}
return indices;
""",```

[vagrant adder]

@maiden bay don't return statuses, return message in a body

[brittle cradle]

Could someone please help me figure out how I can merge these codes together? I could paste what I've drafted but it's a complete nonsensical mess lol

[vagrant adder]

That way users can differentiate if request went badly or name is taken

[maiden bay]

is this how REST supposed to work though?

[vagrant adder]

Yes it is

Status codes are to desribe request as a way to send/retrieve data from an api and request body is a message that is from/to server

[maiden bay]

I would need to invent my own error codes then and include in response to let frontend display localized error message

[vagrant adder]

I don't understand what you just said

[maiden bay]

frontend can't show user raw error message from json response, it would need to translate it first

[vagrant adder]

what do you mean can't show user raw error message from json response

yes you can

request.body

in flask

[cloud path]

anyone can help me with this?

this is the init

this is the code that gives the errors

[tranquil robin]

ur welcome

[native tide]

hey.. ive decided to learn Flask and am following Corey Schafer.. any good text sites or resources ? like amazon books ?

best place for an intermediate pythonner

[marsh canyon]

id say watch all the tutorials and then start working on projects.
Start with simple projects like a todo app, dictonary, etc and then do some complex ones (like twitter clone website, etc).
As you increase the complexity of the projects, you will start learning new stuff, like finding things on the docs, so (my opinion) is to do more projects and learn as you go along

[native tide]

its a good idea.. i need to get the basics of flask first tho

prob cant watch all the tuts

soo many

😉

but thanks

[elfin lance]

with quart and it's websockets, how can I change the session values from a totally unrelated async function

I am trying to make the user send a random generated code to a discord bot and have it set the session values when that matches

[marsh canyon]

@native tide if you dont wanna watch all the tuts but want to get the hang of basics, then freecodecamp on youtube has some flask tutorials too! some of them are under 1 hour

https://www.youtube.com/results?search_query=freecodecamp+flask

[native tide]

@marsh canyon NICE! thanks

i did also find this: https://www.udemy.com/course/the-build-a-saas-app-with-flask-course/?LSNPUBID=jU79Zysihs4&ranEAID=jU79Zysihs4&ranMID=39197&ranSiteID=jU79Zysihs4-kx6mBsk1Jvyp3He3qD7CHQ

[marsh canyon]

cool cool 🙂

[native tide]

but your is more affordable

[marsh canyon]

lol

[native tide]

heh.. tho the saas app course also has some vids on docker

which i also need to learn

my company uses docker in a major way

and im totally blank on that

[marsh canyon]

oki

[native tide]

i like how flask apparently has ready made extensions ?

thats awesome

like if i need a map for stuff, its there for the taking ?

[marsh canyon]

not very experienced with flask, cant comment on that 😅

[native tide]

oh

ok

omg

https://github.com/flask-extensions/Flask-GoogleMaps

[tranquil robin]

@native tide just a note I figured out while watching Corey Schafer, his whole Flask series is based on the book "Flask Web Development by Miguel Grinberg"

Miguel Grinberg also has a website with tutorials called Mega tutorial or so

[native tide]

AHA... son of a gun.. i almost bought grinbergs book..

i actually bought the udemy flask course.. seemed so smooth

[tranquil robin]

this was the website i was talking about

https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world

[native tide]

its very nice

[tranquil robin]

GL 🙂

[native tide]

thank you

am also gonna read the grinberg blog

[vagrant adder]

@native tide i have a cheatsheet that i use for reminder

[native tide]

ohhh

fancy

[vagrant adder]

https://s3.us-east-2.amazonaws.com/prettyprinted/flask_cheatsheet.pdf

[native tide]

@vagrant adder thank you very much.. i am not flask smart enough yet to see its full potential but thank you

[vagrant adder]

If you get into some troubles feel free to jump in here

[native tide]

oh you bet.. thank you..

[vagrant adder]

🤘

[native tide]

im prob gonna start with greenberg and then do the kinda scary udemy flask/docker tut

lots of stuff im unfamiliar with

[vagrant adder]

I started from corey's tutorial series

[native tide]

soo.. maybe start there

i like corey

[vagrant adder]

He goes over a lot of flask's features in that

And i found myself going to that tutorial more times than not

[native tide]

the udemy course is based on building an actual money making app but mentions modules i have never heard of, like celery, redis and gunicorn

[vagrant adder]

Gunicorn is webserver

[native tide]

ah

[vagrant adder]

Really easy to start, one line

Celery and redis are 90% of times not needed

[native tide]

its like background workers ?

[vagrant adder]

They are task schedulers and cache managers

Yes exactly

[native tide]

ah

a lot of the stuff used if not all of it, is based on using docker.. bc its allready set up

[vagrant adder]

And most of the times scheduled tasks are some kind of database interaction which be done with cron

Yes, dockered setups often use redis but i recommend starting before docker

So you can actually get to know your os

[native tide]

yeah im gonna start with corey

[vagrant adder]

👍

[native tide]

stick with that for a while

prob gonna take months to get to a decent level

thanks

🙂

[vagrant adder]

👍

[amber harbor]

hello .. uwsgi .. how do i get all the workers to share the same mysql connection pool?

[vagrant adder]

i don't think that's possible

can your database accept multiple connections?

[amber harbor]

yes

and each workers has a connection pool to the database

and each wokrer has only one connection per pool

[trail thunder]

other than having a single connection act as a proxy, i don't see it being possible either

[sturdy marlin]

My problem:
I'm trying to add a Submission to an Idea. An Idea can have many submissions, a Submission can have only one Idea. I want to validate my form (which is working, with no valid) by checking if the author of the new submission has already created one against an Idea.

Hi guys, I need some help with django and graphQL

Basically I'm given shopify link with access token, I need to build api to get get my products with graphql

[native tide]

i just want to know if you have the pay if you build a website which includes payment methods

i want to know if i have to pay for the hosting server

[native tide]

i want to build a webstore for someone

[rigid laurel]

Payment processing is usually best done through Paypal's or Stripe's API, so you just access those like normal APId

I'm not really sure what your question actually is though

[native tide]

Bokeh is about DataScience

My gamer name is Beerykenny .lol

@rigid laurel i want to create a website

A webstore

Something like Amazon but not that that advanced

I want to put products on it so people can buy them via online

But how?

[rigid laurel]

The same way you'd create a normal website. You'd then interface with PayPal to handle payment

Through a rest api

[native tide]

what is a rest api

[rigid laurel]

you make http requests to them and they return json information

[native tide]

so that is backend

what programmin lan do you use for that

[rigid laurel]

You'd just use your Django/Python to talk to the Paypal API

e.g using requests to send a request to Paypal's servers

Oh - actually, it might need some JS. I haven't touched paypal in a long time

[native tide]

can you maybe

point me in the right direction

where to start

tutorial or something

[rigid laurel]

https://www.youtube.com/watch?v=qKS87S0Imsk

https://overiq.com/django-paypal-integration-with-django-paypal/

https://django-paypal.readthedocs.io/en/stable/

I can't say how good/bad those are. But they seem like they should let you get started.

[native tide]

ok

thx

[tranquil robin]

@native tide edx harvard cs50w has one of its projects (i think the third one) about creating a pizza webstore

u can check the lectures and content needed for that

[native tide]

ok

this course you mean

CS50's Web Programming with Python and JavaScript

[weary arrow]

I've a flask app and I want a button to start/stop a python script that runs indefinitely without refreshing the page. is the best way to go about this ajax and having the start button launch a process and the stop kill it?

[rigid laurel]

Setup an endpoint that starts off your process, and an endpoint that kills your process. Its probably best to make them return json. If starting/stopping the script requires information, then you can take that as a url param, or change the endpoint to be a post and take it as a json paramater

[weary arrow]

any examples? Not sure where to start with that. I was thinking starting a subprocess in a function and then killing it in another one, and tying those to buttons with some javascript

[rigid laurel]

@app.route('/start-script')
def start_script():
    # Some code here that starts your script. 
    # I don't know how this works, but its the same as in a normal function
    return jsonify({"status": "script started"})

then from the js side, you'd set the button that starts the script to make a request as part of the onclick

[weary arrow]

hmm and I could probably set a variable somewhere in the script that checks whether or not it should be running. and in stop_script just modify it

no need for subprocess then

[cloud path]

why this issue guys?

[quasi ridge]

the issue is: please paste text, not images

[cloud path]

1 moment

from app.models import User, Post

@app.shell_context_processor
def make_shell_context():
    return {'db': db, 'User': User, 'Post': Post}```

[quasi ridge]

I suspect the issue is: after you ran flask shell, you forgot to import your code

you probably need to type import my_stuff, and then you can type my_stuff.db and it might work

or maybe you need to type from app import db

[cloud path]

the function should be to avoid having to import things into the shell, or so the tutorial says this

https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-iv-database this tutorial at the last paragraph

[quasi ridge]

oic

The only thing I can think of is: you somehow put your make_shell_context in the wrong file

[cloud path]

mm now i check better, this mistake is strange, i will do in the old way if i can't solve it

thank you for the support anyway!

Solved! I accidentally called the name of a dictionary entity with the same name as the tutorial, and not with what I gave it, lol

indeed db command still does not work, oh well lol

[tranquil robin]

<body>
  <nav></nav>
  <div></div>
</body>

Is there a way I can let the div take an automatic height size that is equal to the remaining screen size not used by the navbar?

[cerulean vapor]

@tranquil robin I think the only way to do that is with JS

get the height of the navbar, subtract the screen size, set the div to that height, and trigger all that in an onresize event for the window

I don't think there's any pure CSS solution

[tranquil robin]

got it

give the navbar for example 10vh height and the 90vh to the div 🙂

but for some reason the pc is bugging out, I cant click the navbar buttons -,-

[cerulean vapor]

If you use fixed heights for each it would work, just not if you want dynamic resizing

like, if you hard-assigned 10vh and 90vh, that's fine, but if you wanted to change based on the contents of each, that's another story

[tranquil robin]

nah its just a search page with a navbar and searchbar div

[cerulean vapor]

OK, then you could use fixed sizes

vh is a wonderful invention
