Hi all

DATETIMES and TIMEZONES. What the hell.

I am building a chat feature into a website and currently all of the users are on one timezone but if it starts getting users from a different timezone will that mess up the time stamps of the message if the time stamps are timezone naive?
Wondering if the solution would be to have timestamp timezone as UTC and then asking the user to give their timezone to do the conversion. Help please 😂

zealous siren Sep 17, 2020, 2:46 PM

#

most systems store time in UTC then convert

tepid stirrup Sep 17, 2020, 3:06 PM

#

@zealous siren Thanks so I will have to get timezones from the user

zealous siren Sep 17, 2020, 3:07 PM

#

I believe you can with Javascript

tepid stirrup Sep 17, 2020, 3:09 PM

#

Aw okay thanks for that. I will look into it.

sly canyon Sep 17, 2020, 3:18 PM

#

@tepid stirrup I'd go with datetime.utcnow() to register everything. you can format times according to the user's location using other tools.

#

moment.js, pendulum, ....

vale orbit Sep 17, 2020, 3:30 PM

#

are there any good python library for manipulating the DOM, or do I have to use javascript for that?

#

I'm trying to figure out just how full-stack I can get with Python

zealous siren Sep 17, 2020, 3:32 PM

#

if you are trying to make a modern site, backend only with python

#

Frontend will be mostly to all JS/TS

vale orbit Sep 17, 2020, 3:32 PM

#

.....well fuck

sly canyon Sep 17, 2020, 3:33 PM

#

@vale orbit I feel the same

vale orbit Sep 17, 2020, 3:33 PM

Guess I cannot put off learning JS any longer then

sly canyon Sep 17, 2020, 3:33 PM

#

Python on web front-end ASAP

#

I almost hate JS

vale orbit Sep 17, 2020, 3:33 PM

#

from what I understand, TS isn't nearly as cancerous as JS, so I guess there's that?

sly canyon Sep 17, 2020, 3:33 PM

#

but it's an evil we have to deal with

vale orbit Sep 17, 2020, 3:34 PM

#

I hate JS, but not nearly as much as I hate Java

sly canyon Sep 17, 2020, 3:34 PM

#

never tried, probably never will.

vale orbit Sep 17, 2020, 3:34 PM

#

remember when Java was all about making OOP faster and more effective?

I remember. It has been a long time since then.

#

but I digress

zealous siren Sep 17, 2020, 3:34 PM

it did when it came out

tepid stirrup Sep 17, 2020, 3:35 PM

#

@sly canyon Thanks! How does that work with dates and times set by the user just for future ref

sly canyon Sep 17, 2020, 3:35 PM

#

JS has nothing to do with Java, thankfully

zealous siren Sep 17, 2020, 3:35 PM

#

but like many legacy stuff, it aged poorly

sly canyon Sep 17, 2020, 3:35 PM

EC6 was just trying to make a name that would catch

vale orbit Sep 17, 2020, 3:35 PM

#

It was rushed.

#

They were like "we need to get this language out now, even if it barely works"

zealous siren Sep 17, 2020, 3:36 PM

#

yea, but getting offtopic, point is, good frontends will be Javascript frontends

#

look into React/Vue/Angular

vale orbit Sep 17, 2020, 3:36 PM

#

Ok, so over-under on Svelte JS?

sly canyon Sep 17, 2020, 3:36 PM

#

@tepid stirrup you can request.remote_addr and do some GeoIP to guess their location/timezone

zealous siren Sep 17, 2020, 3:37 PM

#

edug, that's just delaying doing proper thing

tepid stirrup Sep 17, 2020, 3:37 PM

@sly canyon What I mean is like if they wanted to make a start and end time for a task but it was a planner or something like that.

re: Flask routing - is there anything inherently wrong with combining get and post endpoints in the same entry, or should I create an @app.route() for each?

nothing wrong in my POV, sometimes even necessary for me to avoid argparsing

@sly canyon could I perhaps have you take a look at my example and get your feedback on why it might be causing a 500 error?

both get and post return 500, and nothing of any use is getting logged

sly canyon Sep 17, 2020, 4:24 PM

you don't need if request.method == 'GET': 'cause thats the default behavior

white tree Sep 17, 2020, 4:25 PM

oh. I wasn't sure how to differentiate - guess I should've read the docs more thoroughly, haha.

#

that said - it does work... most of the time.

#

but for reasons I can't quite figure (which is why Im here) after a while, it stops working and just returns 500.

sly canyon Sep 17, 2020, 4:26 PM

#

I'm really not sure why that is

white tree Sep 17, 2020, 4:26 PM

the logs only show WSGI errors with the queries being executed

sly canyon Sep 17, 2020, 4:26 PM

maybe something related to your databse

white tree Sep 17, 2020, 4:27 PM

#

well, I thought the same at first two. its just a standard local only mysql. but when I mysql console, it executes queries just fine.

#

I was however curious about the request object. perhaps Im expecting the wrong behavior from it?

sly canyon Sep 17, 2020, 4:28 PM

#

does the internal error happens on local env or only in production?~~~~

white tree Sep 17, 2020, 4:28 PM

#

its a personal project, so Ive just been tinkering with it on production (I know, bad form)

sly canyon Sep 17, 2020, 4:29 PM

#

thatn that's probably why

#

you're expecting the production server to access stuff that are not there

#

your local db is not in the production server, most probably

when I say local only - I meant - closed off from external connection. it's "local" to the app.

is it possible to create a variable name using javascript based on an user input?

white tree Sep 17, 2020, 5:04 PM

#

no.

proper hinge Sep 17, 2020, 5:04 PM

#

Why would you need to do that?

#

That sounds like an xy problem

white tree Sep 17, 2020, 5:05 PM

#

@proper hinge I get the meaning, but have never heard that expression. care to elaborate?

proper hinge Sep 17, 2020, 5:06 PM

#

x is what they really want to do and y is how they want to do it, but y is not actually a good solution for x

#

So they should be asking how to do x, not how to do y.

#

i.e., the root of the problem

vague ibex Sep 17, 2020, 5:07 PM

#

@proper hinge I have a problem. Can you help solve it?

#

I just the need the idea.. rest I can code

proper hinge Sep 17, 2020, 5:07 PM

#

I'm not sure. What is the problem

vague ibex Sep 17, 2020, 5:08 PM

#

So basically I have 5 setintervals. Now, I want to stop a particular interval and want to keep the rest running as normal. So, what should I do?

lethal orbit Sep 17, 2020, 5:08 PM

#

Assign them to a variable?

#

What are the 5?

proper hinge Sep 17, 2020, 5:09 PM

#

Use clearinterval to stop the one you need.

lethal orbit Sep 17, 2020, 5:09 PM

#

Why does the name need to be user-defined?

vague ibex Sep 17, 2020, 5:10 PM

#

yea that's a pretty cool solution. But the problem I am facing is : suppose 100 users set their setintervals. Now, I wanted to assign them to variables which would be suggested by the users to keep it more comfortable.

proper hinge Sep 17, 2020, 5:10 PM

#

Why? Cause you need to be able to stop a specific user's interval?

vague ibex Sep 17, 2020, 5:10 PM

#

yea!

proper hinge Sep 17, 2020, 5:10 PM

#

If that's the case, store the interval ideas in a dictionary

#

And use the user's ID or something else to identify it

maiden kraken Sep 17, 2020, 5:11 PM

#

Hello. I am having my Django project on github as private repository, but I posted some screen online about ideas for development and some guy askes sincere about checking my github code and giving me more specific advice. Is it safe to share my github code? I have all the files there, including settings.py and my sqlite3 database.

vague ibex Sep 17, 2020, 5:11 PM

#

If that's the case, store the interval ideas in a dictionary
@proper hinge what do you mean by dictionary?

proper hinge Sep 17, 2020, 5:11 PM

#

They're just called "objects" in JS I guess

#

A key-value mapping

#

A hashmap

lethal orbit Sep 17, 2020, 5:12 PM

#

@maiden kraken does your settings.py contain Secret Keys and other private data?

vague ibex Sep 17, 2020, 5:12 PM

#

yea objects are fine but still, is there not any more easy techniques?

proper hinge Sep 17, 2020, 5:12 PM

#

I don't see how it could get any easier

lethal orbit Sep 17, 2020, 5:12 PM

#

it is safe to share code if it is just code....

maiden kraken Sep 17, 2020, 5:12 PM

#

Im afraid it does. What is the meaning of secret code anyway?

lethal orbit Sep 17, 2020, 5:13 PM

#

(unless you have bugs you can exploit lol)

maiden kraken Sep 17, 2020, 5:13 PM

#

Should I input new setting.py without secret code?

lethal orbit Sep 17, 2020, 5:13 PM

#

The proper way is to keep SECRET_KEY and database settings outside of your repo.

#

You should definitely never ever commit your database (unless it's for a test app).

vague ibex Sep 17, 2020, 5:14 PM

#

@proper hinge So, you say that making objects will be better?

proper hinge Sep 17, 2020, 5:14 PM

#

You can technically create variables with dynamic names, but this involves essentially modifying an object anyway, so it's a more hacky way of managing your own object. It's not really advantageous since presumably you'd need to dynamically retrieve those same variables too.

vague ibex Sep 17, 2020, 5:14 PM

#

Can setinterval functions work while being inside an object?

proper hinge Sep 17, 2020, 5:14 PM

#

Yes

#

The functions aren't inside an object

lethal orbit Sep 17, 2020, 5:15 PM

#

Should I input new setting.py without secret code?
@maiden kraken you would have to change the secrets...

proper hinge Sep 17, 2020, 5:15 PM

#

They just return an ID

#

and you're storing the ID in an object

lethal orbit Sep 17, 2020, 5:15 PM

#

Once they are in git, you can easily see past commits.

vague ibex Sep 17, 2020, 5:15 PM

#

so where am I storing the functions?

proper hinge Sep 17, 2020, 5:15 PM

#

Functions don't get stored

#

They get called

lethal orbit Sep 17, 2020, 5:15 PM

#

Just removing it won't scrub it.

vague ibex Sep 17, 2020, 5:15 PM

#

I mean, How do i stop the intervals

#

a specific interval according to an user

proper hinge Sep 17, 2020, 5:15 PM

#

By using the ID they return

#

setinterval returns an ID. If you pass that ID to clearinterval, it will stop it

vague ibex Sep 17, 2020, 5:16 PM

#

oh man, I didn't even know that

maiden kraken Sep 17, 2020, 5:16 PM

#

@lethal orbit yeah I know I messed up. It was hard for me since I learn git as well with this project. Anyway I think since this is just a side project for portfolio I can share it

vague ibex Sep 17, 2020, 5:16 PM

#

How do I get that ID ?

proper hinge Sep 17, 2020, 5:16 PM

#

Like I said, it's what the function returns

maiden kraken Sep 17, 2020, 5:16 PM

#

@lethal orbit thanks for advice

lethal orbit Sep 17, 2020, 5:16 PM

#

Do you have the website running in production @maiden kraken?

maiden kraken Sep 17, 2020, 5:17 PM

#

no, I am still running it from local server, I use git as a private repo basically as a safe copy

vague ibex Sep 17, 2020, 5:17 PM

#

Where do I store the ID and how do I interpret it?

lethal orbit Sep 17, 2020, 5:17 PM

#

Well, if it is not running in production, sharing it ~~won't~~ shouldn't hurt 🙂

maiden kraken Sep 17, 2020, 5:18 PM

#

thanks a lot, you are not helping me the first time, I really appreciate your help 🙂

proper hinge Sep 17, 2020, 5:18 PM

#

Store the ID in an object

vague ibex Sep 17, 2020, 5:18 PM

#

so a setinterval will have a specific ID Right and it wont change?

proper hinge Sep 17, 2020, 5:18 PM

#

Make the user's name/ID the key, and the setinterval ID the value

#

Correct

vague ibex Sep 17, 2020, 5:19 PM

#

how do i add it?

#

i mean

#

how is the value extracted?

proper hinge Sep 17, 2020, 5:19 PM

#

Extracted from the object?

vague ibex Sep 17, 2020, 5:19 PM

#

I mean when do i get the id

#

and where

proper hinge Sep 17, 2020, 5:20 PM

#

It is returned by setinterval

#

I've noticed you have asked that a few times. Are you unfamiliar with how functions return things?

vague ibex Sep 17, 2020, 5:21 PM

#

Yea

#

Haven't worked quite well with these things tbh. I've been focusing on deeper front end stuff (without deeper js)

#

@proper hinge What about I give the user the id to keep it with them? lol

#

Whenevr they want to force close the intrval, they can just enter the id

proper hinge Sep 17, 2020, 5:23 PM

#

let id = window.setInterval(...)
window.clearInterval(id)

lethal orbit Sep 17, 2020, 5:23 PM

#

@maiden kraken the proper way to do things:

# settings.py
SECRET_KEY = os.environ.get("DJANGO_SECRET_KEY")  # and save a key in en environment variable called DJANGO_SECRET_KEY
# do the same thing for Database Settings if you use postgres/mysql which require a username/pw

And add a .gitignore file:

# Database
sqlite.db
# Editor settings
.vscode
.idea
``` etc.

proper hinge Sep 17, 2020, 5:23 PM

#

Basically that, except you need to store each id in an object to associate it with a certain user

vague ibex Sep 17, 2020, 5:23 PM

#

cool

#

btw do all functions return id or only setintervals/settimeouts?

maiden kraken Sep 17, 2020, 5:24 PM

#

@lethal orbit Thank a lot, my laziness is just biting me in the ass, I wanted to push forward with the code as far as I could and ignored... ignoring 🙂 It's a lesson for the future

lethal orbit Sep 17, 2020, 5:25 PM

#

All good. part of the learning process 🙂

proper hinge Sep 17, 2020, 5:25 PM

#

Each function returns something different, as functions are designed to perform different tasks. Some return nothing even. You'd need to read the documentation to know what each function returns.

lethal orbit Sep 17, 2020, 5:25 PM

#

~~My decisions also always bite me in the ass months down the line~~ lol

maiden kraken Sep 17, 2020, 5:26 PM

#

yeah, might as well get use to it 🙂

vague ibex Sep 17, 2020, 5:27 PM

#

aight thanks friends! It really helped me1 😄

lethal orbit Sep 17, 2020, 5:27 PM

#

You can also look for .gitignore files online: https://github.com/github/gitignore ... Python.gitignore is a good starting place.

vague ibex Sep 17, 2020, 5:29 PM

#

let a = setInterval(function(){console.log('a')},2000); let poke = { "o1" : setInterval(function(){console.log('a')},2000) };
clearInterval(poke.o1);

#

why did it not work?

#

the interval kept on repeating

lethal orbit Sep 17, 2020, 5:30 PM

#

Don't you need a scope?

#

window.setInterval();
window.clearInterval();```

vague ibex Sep 17, 2020, 5:31 PM

#

you mean the window?

lethal orbit Sep 17, 2020, 5:32 PM

#

Yeah

#

let a = window.setInterval(...

vague ibex Sep 17, 2020, 5:32 PM

Hi again, I am making a discussion board site. I have now login and logout functionality. How do I get username if the user is logged in and auto input it into a form so when the post is added it is added by this user?

#

This is my views.py but this doesnt work

#

def add_response(request): if request.user.is_authenticated: if request.method == 'POST': new_response_form = CreateResponseForm(data=request.POST) if new_response_form.is_valid(): new_topic = new_response_form.save(commit=False) new_topic.author = request.user.id new_topic.save() new_topic_form = CreateResponseForm() else: new_topic_form = CreateResponseForm()

are u using the default User model?

maiden kraken Sep 17, 2020, 6:28 PM

#

hmm yes, I also am extending default User with 1to1 relation but I think that is not changing much

marsh canyon Sep 17, 2020, 6:30 PM

#

right

#

in ur code, u have got the user id by doing request.user.id, you can get the username in a similar way, request.user.username

maiden kraken Sep 17, 2020, 6:31 PM

#

hmm, I think i don't really care if it is user id or name I think.. Problem is I get this:

#

NOT NULL constraint failed: homepage_forumresponse.author_id

#

and then

#

params

[None, '<p>test</p>', '2020-09-17 18:25:09.355271', 1]

#

first none is the author from what I assume

#

and it's None instead of name/id

#

yeah, from sql query I see that author is empty

maiden kraken Sep 17, 2020, 6:54 PM

Okay, managed to solve it myself thanks

topaz widget Sep 17, 2020, 6:55 PM

Hey does anyone know if there's any danger of SQL injection in simply using request.POST.get(...) to access POST body data from a form with Django?

#

I use the data from request.POST.get(...) in the constructor of an object that will be stored in the database, but I'm pretty sure it utilizes the ORM so I should be safe, right?

#

I don't write any SQL commands, just call the object's save method.

maiden kraken Sep 17, 2020, 7:22 PM

#

@topaz widget im a beginner, but isn't csrf_token protecting you from this in any way?

topaz widget Sep 17, 2020, 7:25 PM

#

@maiden kraken No, CSRF token protects against cross-site request forgeries, not SQL injection.

#

Very different method of attack.

#

@maiden kraken You should definitely read up on SQL injection, CSRF (cross-site request forgeries), and Cross-Site Scripting (XSS). They're probably the most common hacking methods / vulnerabilities for web applications and each require different practices to defend against.

hallow jacinth Sep 17, 2020, 7:37 PM

oh nvm found a link

topaz widget Sep 17, 2020, 7:37 PM

#

@hallow jacinth Why are you not using bootstrap 4? I think that's what version they're on now.

hallow jacinth Sep 17, 2020, 7:38 PM

#

because flask-boostrap doesn't support it, and I am too lazy to go and download and use raw bootstrap 4

topaz widget Sep 17, 2020, 7:40 PM

#

@maiden kraken Sure thing. The basic gist:
CSRF: Exploiting your authentication to make sensitive requests from outside your session.
XSS: Exploiting an insecure web application that allows raw user-generated HTML to inject JavaScript into the application.
SQL injection: Loading SQL (Structured Query Language) commands onto the database, which are not handled property to access or modify information the user shouldn't be able to.

#

Some of these attack methods can be used in tandem.
For instance, XSS can be used to pull credentials (cookies) from another user of the site, which then can be used in a CSRF attack to make privileged requests under the identity of the user whose identity has been stolen.

maiden kraken Sep 17, 2020, 7:43 PM

#

Since you're fairly advanced, I guess using something like tinyMCE and allowing storing html into your models isnt very safe?

topaz widget Sep 17, 2020, 7:43 PM

#

Well, nothing I'm working on requires tinyMCE, but I have messed around with it a bit.

#

But yes, I would use something like that so users can't write their own HTML.

#

You can manually "white-list" certain HTML if you want to let users get more creative, but it's a pain in the ass to implement.

maiden kraken Sep 17, 2020, 7:45 PM

#

it's just scares me since I am using python as a hobby how much stuff you have to know 🙂

topaz widget Sep 17, 2020, 7:46 PM

#

It's good that you're scared. There are a lot of ways things can go wrong that won't even cross your mind as a non-expert.

@coral raven

"Drop a star" lol, sounds like a youtube video.

topaz widget Sep 17, 2020, 7:46 PM

#

Even the expert miss vulnerabilities, too.

#

I don't know if you remember the HEARTBLEED vulnerability, but that was a big deal not too many years ago.

maiden kraken Sep 17, 2020, 7:48 PM

#

I am reading about it, as you said, if you do something there is always a risk

topaz widget Sep 17, 2020, 7:49 PM

#

It really depends on how secure your application needs to be.

near forge Sep 17, 2020, 7:49 PM

#

@topaz widget and to answer your questions, django queries are escaped

topaz widget Sep 17, 2020, 7:49 PM

#

@near forge lol thanks. I'm here for my own security concerns.

#

Anyway, if you're making bank software, that better be airtight.

near forge Sep 17, 2020, 7:50 PM

#

Before you concern yourself about security, you should ask yourself what you are securing.

topaz widget Sep 17, 2020, 7:50 PM

#

If you're making some rant blog, it probably doesn't have to have NSA-level security.

maiden kraken Sep 17, 2020, 7:50 PM

#

thanks for a nice discussion, I g2g

topaz widget Sep 17, 2020, 7:51 PM

#

np, take it easy.

near forge Sep 17, 2020, 7:53 PM

#

@topaz widget hopefully you have colleagues and tests before pushing bank software to production.

topaz widget Sep 17, 2020, 7:53 PM

#

Yes, of course. But even professionals miss things. Kevin Mitnick has entered the chat

#

Better yet: Frank Abagnale has entered the chat

#

Though Abagnale was check fraud.

#

("Catch Me If You Can" was based on his exploits)

near forge Sep 17, 2020, 7:56 PM

#

Anyhow as in any company, security should be on par with the services you provide.

#

There's really no point in making an air tight social app that no one uses.

topaz widget Sep 17, 2020, 7:56 PM

#

Um...

#

Might as well get security right from the start, though.

near forge Sep 17, 2020, 7:57 PM

#

But of course when money is involved. The best thing you can do is implement SOTA protocols for handling it.

#

That's just a waste of time imo.

#

It's an endless task.

topaz widget Sep 17, 2020, 7:58 PM

#

SOTA? State of the art?

near forge Sep 17, 2020, 7:59 PM

#

yes, usually there's is someone out there that's thought about security. As in django things are pretty secure if you just follow the guidelines.

#

My point is it's usually a better and easier to use already existing tools than implementing your own security measures.

topaz widget Sep 17, 2020, 8:01 PM

#

You mean like not writing raw SQL commands, only using the | safe filter when you know you can trust the content, and using csrf_token in all your forms?

near forge Sep 17, 2020, 8:02 PM

#

I guess, you better read the docs. I don't know them all by heart.

topaz widget Sep 17, 2020, 8:03 PM

#

Oh yeah, right, there are a bunch of others on their "checklist" I wasn't thinking of (but use)

weak chasm Sep 17, 2020, 8:18 PM

#

Anyone familiar with httpresponseredirect?
I'm redirecting a user to a google api link, they sign in, authorize access, confirm, etc, then it returns with the "code" necessary in the redirect URL so that I can next fetch a token.
However, it seems that my code might need to pause momentarily until the user finishes all of this stuff. Otherwise, code keeps running and I get errors b/c response not back yet from user's actions.

My question is http response redirect the best tool. or even if it isn't, should i be looking to something like celery to make a task scheduler?

clear fjord Sep 17, 2020, 8:54 PM

#

Hey guys anyone know how I can run a function at a time specified by the user In flask

topaz widget Sep 17, 2020, 9:16 PM

#

@clear fjord cron. Not in flask though, in Linux.

#

Actually, wait, maybe cron isn't so good if the user is specifying the time.

clear fjord Sep 17, 2020, 9:17 PM

#

Yea

#

I was looking for a code solution

#

And since my client is not hosting on his laptop because its a small program just for him

#

if it restarts

#

it also needs to re add the tasks

topaz widget Sep 17, 2020, 9:18 PM

#

I'm not sure how you would do that from within Flask.

clear fjord Sep 17, 2020, 9:18 PM

#

Right now im just saving the entries in database

topaz widget Sep 17, 2020, 9:18 PM

#

Maybe you could use time.sleep() and then just specify the time between when the user made the request and when it's supposed to happen.

clear fjord Sep 17, 2020, 9:19 PM

#

I was thinking run the function from a url

#

and take an id in the url

#

and run the task depending on id and have another program run the url

#

or something

weak chasm Sep 17, 2020, 9:19 PM

#

messaging queue maybe?

topaz widget Sep 17, 2020, 9:19 PM

#

Although, I don't think time.sleep() could be done asynchronously, so maybe that's not such a good idea.

clear fjord Sep 17, 2020, 9:19 PM

#

let me see if it can be used asynchronously

#

maybe some library or something i dont know

topaz widget Sep 17, 2020, 9:20 PM

#

Well, you can write an asynchronous function.

clear fjord Sep 17, 2020, 9:20 PM

#

Yea I can do that

#

and then run the url it runs the function

topaz widget Sep 17, 2020, 9:21 PM

#

I'm just saying I don't think time.sleep() is natively asynchronous like setTimeout in JavaScript is.

clear fjord Sep 17, 2020, 9:21 PM

#

node flask hybrid 😳

topaz widget Sep 17, 2020, 9:21 PM

topaz widget Sep 17, 2020, 9:21 PM

#

How tf are you using node with Flask?

clear fjord Sep 17, 2020, 9:22 PM

#

im not lmao

topaz widget Sep 17, 2020, 9:22 PM

#

or was that a joke?

#

okay lol

clear fjord Sep 17, 2020, 9:22 PM

#

i could use node to run functions

#

"the function"

topaz widget Sep 17, 2020, 9:22 PM

#

It sounds to me like some asynchonous function might be best, but...

clear fjord Sep 17, 2020, 9:22 PM

#

node has alot of library like that

#

yea ill try that

topaz widget Sep 17, 2020, 9:23 PM

#

you might run into problems if a lot of users run asynchronous functions.

clear fjord Sep 17, 2020, 9:23 PM

#

just 1 user

#

its for himself

#

hosting on his laptop

#

he gonna leave running 24/7

topaz widget Sep 17, 2020, 9:23 PM

#

So this is only for him? And he is admin?

clear fjord Sep 17, 2020, 9:24 PM

#

yea

topaz widget Sep 17, 2020, 9:24 PM

#

What OS is he using?

clear fjord Sep 17, 2020, 9:24 PM

#

windows if im not mistake

#

n

topaz widget Sep 17, 2020, 9:24 PM

#

Just use task scheduler then.

clear fjord Sep 17, 2020, 9:24 PM

#

k let me try that

topaz widget Sep 17, 2020, 9:24 PM

#

Are you on Windows?

weak chasm Sep 17, 2020, 9:27 PM

#

@topaz widget task scheduler like celery. I'm wondering though are you able to break a function into 2 tasks. like
def main():
task 1 do something
httpresponseredirect
celery wait until http response is back from user completing action on a different url
task 2 do something else
return

topaz widget Sep 17, 2020, 9:28 PM

#

@weak chasm No, Windows Task Scheduler.

#

This is admin-level stuff. Could just be done right on the system.

#

And it might be better for this guy to use Windows Task Scheduler if he's not a coder himself.

vestal hound Sep 17, 2020, 9:50 PM

#

Although, I don't think time.sleep() could be done asynchronously, so maybe that's not such a good idea.
@topaz widget it's not; you would use asyncio.sleep in that situation

topaz widget Sep 17, 2020, 9:51 PM

#

you should ping omar on that message, too.

@weak chasm what backend

weak chasm Sep 17, 2020, 10:07 PM

#

@vestal hound very new to webdev. Idk what you're talking about. lol
I'm using python django with heroku , but not not really using their built in middleware or whatever else they have.(Turned out I like flask more, but too late to go back)

vestal hound Sep 17, 2020, 10:16 PM

#

@vestal hound very new to webdev. Idk what you're talking about. lol
I'm using python django with heroku , but not not really using their built in middleware or whatever else they have.(Turned out I like flask more, but too late to go back)
@weak chasm so Django is your backend

#

vanilla Django or DRF?

weak chasm Sep 17, 2020, 10:16 PM

#

how do i check?

vestal hound Sep 17, 2020, 10:16 PM

#

if you don't know, it's vanilla Django

#

DRF = Django REST Framework

weak chasm Sep 17, 2020, 10:17 PM

#

oh vanilla

vestal hound Sep 17, 2020, 10:17 PM

#

so basically

#

you have a view where you need to do two things: get some data from somewhere else, and get some data from the user

#

and you only want to proceed after both of these things have been done

#

correct?

weak chasm Sep 17, 2020, 10:19 PM

#

Haven't gotten that far. Was writing helper functions in another file to be called in views.py I guess. will have to figure out if I need to do something with models.py and displaying data to my index.html page

#

so yes

vestal hound Sep 17, 2020, 10:20 PM

#

huh.

#

why do you want to use a redirect then

#

seems a bit complicated

#

async views should work just fine

#

actually, wait, let me think

weak chasm Sep 17, 2020, 10:21 PM

#

I need the user to login to their google account and confirm authorization for my web app so I can get token access in future and play around with that stuff.

vestal hound Sep 17, 2020, 10:21 PM

#

feels like

#

you're trying to solve multiple problems at once

#

maybe you can list out the steps in the intended experience from the user's perspective

weak chasm Sep 17, 2020, 10:25 PM

#

type my webapp url into browser
my web app will redirect you to google api website so you can login and confirm access to my application
user should be taken back to the my webapp.
I will take the code embedded within the redirect url to fetch the token to have future access of the application
list emails or list file in drive for the user
do some magice on emails and files to create some end product for user
user does some stuff

#

? i guess O_o

vestal hound Sep 17, 2020, 10:30 PM

#

hm

#

okay

#

so where is it that you are thinking "what if the user's not done?"

weak chasm Sep 17, 2020, 10:30 PM

#

oh i added 5-7

#

ohhh so if the users not done:

#

the problem is that how does my web app know how fast or slow the user is when loggin into their account and checkboxing the stuff in google api .com website or w/e the url is. my code redirects sure but it keeps going and is thinking it already has the redirect url with the embedded code needed to fetch token. but it doesn't b/c user is slower than a computer executing lines of consecutive code.

vestal hound Sep 17, 2020, 10:33 PM

#

ah, okay

#

because

#

you have redirected

#

so you don't know if the user is done.

#

is that what you mean?

weak chasm Sep 17, 2020, 10:35 PM

#

so
httpresponseredirect(url) --> user goes through the motion of loggin in at google.com
code= request(url).url or something ==> user is not done yet with loggin in&authorizing
code. split("&") --> user is still not done
*here computer throws error variable called 'code' does not have more than 1 element in the list or ssomething like that *

vestal hound Sep 17, 2020, 10:37 PM

#

hm

#

but

#

you are returning a HttpResponseRedirect

#

right?

weak chasm Sep 17, 2020, 10:37 PM

#

correct

vestal hound Sep 17, 2020, 10:37 PM

#

so there shouldn't be code running in your view after that...?

#

because you've already returned

weak chasm Sep 17, 2020, 10:37 PM

#

i didn't return

#

O_O

#

is that function only to be used with views.py

#

O_O

vestal hound Sep 17, 2020, 10:38 PM

#

well, then your redirect won't work, if I understand what you're saying correctly

#

it's not a function, it's a type of Response

#

do you know how HTTP status codes work?

weak chasm Sep 17, 2020, 10:39 PM

#

I know of them. not sure how the codes affect the views.py

#

like 404 not found and 500 you messed up

vestal hound Sep 17, 2020, 10:39 PM

#

yup

#

so basically

#

you know how your views

#

return responses?

#

HttpResponseRedirect is just another kind of response, but with a special status code that tells the browser that receives it "hey go here"

#

it's not a function thaty ou call

weak chasm Sep 17, 2020, 10:40 PM

#

o_o

#

woah

#

my views return responses?

#

return render(request,"index.html")

#

i guess that's a response

#

should i be making a views.py helper function that just redirects

#

and I don't have to worry about the async responses

#

I'm going to try to break up function so I return httpresponseredirect

#

thanks

vestal hound Sep 17, 2020, 10:48 PM

#

yes, render returns a HttpResponse

topaz widget Sep 17, 2020, 11:08 PM

#

@weak chasm Are you trying to render templates to JSON or something? What are you trying to do?

#

If you're using Django, there are some native functions for doing simple redirects.

#

If that's all you're trying to do.

weak chasm Sep 17, 2020, 11:14 PM

#

writing the oauthorization code to ask user to go to google api website(automated not manually) they login and confirm access then it comes back w/ redirect with "code" value within the redirect url. i take that to complete the token fetching process so in the future I dont have to ask the user again. and i'm able to read/write files in say gmail now

I didn't know/ still a bit uncertain how views handles httpresponses, (just know that they do and will be using this fact forward) and then send that to my page index.html. I saw some examples that were deprecated/only for flask that made a class inside models.py.

topaz widget Sep 17, 2020, 11:15 PM

#

I don't think you can do that with gmail.

weak chasm Sep 17, 2020, 11:16 PM

#

you can automate it. you just have to have the user login once at the beginning manually.

topaz widget Sep 17, 2020, 11:16 PM

#

The user would at the very least have to change a setting in their gmail account.

#

I think that would require "allowing insecure apps" to access your gmail via something like SMTP.

#

idk, maybe there is an API, though. I guess there could be.

weak chasm Sep 17, 2020, 11:25 PM

#

there is a google api for server side web applications. even some example code for flask(not django) interestingly enough, after searching for some examples, I found that the google's api authlib i think or something had some sample code for django in git repo. they deleted it. and aren't updating it only maintaining it. even more interesting, the old sample code was for using google plus. so i'm thinking the security fiasco w/ google plus couple years back made them ctrl+f google plus delete all.
change the setting=> yes. was thinking of even automating this one time sign with selenium. but that's too much work not enough reward.
https://developers.google.com/gmail/api/auth/web-server
that one seems more complicated than the one for drive

You can have a basic html web page and then have python scripts to make things happen on the page? Or how can I integrate python to html exactly

topaz widget Sep 17, 2020, 11:42 PM

#

@plucky tapir I think you want to use JavaScript for what you're thinking about. Python is used on the "back-end".

#

Python is used on the server (back-end) to serve up HTML, CSS, and JavaScript (and media) files to the client or browser or front-end.

#

Sounds like you're just getting started on your web development journey.

#

That's why these forums exist, though.

plucky tapir Sep 17, 2020, 11:52 PM

#

Is there a big learning curve for JavaScript? Mainly have to function rather than look nice.
So assuming a basic webpage was built. That had made up user information stored in a database. I’d use python to pull that data, do something to it (add 1.3 % increase for example) and use front end to display it?

topaz widget Sep 17, 2020, 11:52 PM

#

that's pretty much right.

#

It's pretty easy to get started with JavaScript but there is a long path to becoming very good with it. Same with Python.

#

Here's a little more detailed run-down of what each component does in the "web stack":

plucky tapir Sep 17, 2020, 11:54 PM

#

Yeah just c++ for me and some concepts with python. Never implemented any of it to actually create something before though

topaz widget Sep 17, 2020, 11:57 PM

#

HTML: Formats content on a web page. Used for semantic (meaning) and formatting purposes to mark content (called markup)
CSS: Styles HTML content. HTML tags are queried with CSS to apply styling to different HTML elements.
JavaScript: Manipulates the behavior of content on a web page. Can run full programming logic including loops, conditional statements, etc...
Python or Other Backend Language: Serves up content. Accesses database, crunches numbers before sending content to frontend. Processes requests sent from client (frontend)

plucky tapir Sep 18, 2020, 12:03 AM

#

JavaScript can sometimes serve as a backend then if you’re real into it?
What section of python would I want to look into more for this type of backend with python?

C++ isn’t really useful here it looks like

zealous siren Sep 18, 2020, 12:07 AM

#

@plucky tapir it can serve as backend completely

plucky tapir Sep 18, 2020, 12:10 AM

#

@zealous siren with JavaScript?

zealous siren Sep 18, 2020, 12:20 AM

#

yes

#

NodeJS

topaz widget Sep 18, 2020, 12:24 AM

#

@plucky tapir Some people swear by JavaScript (running on a Node.js runtime) for back-end, as it streamlines the development process only needing to use one language for both front and back-end (only JavaScript can run on the front-end).

#

I don't know if it's really comparable to C++, but C# is a popular language for the web back-end using Microsoft's .NET framework.

#

I'm not sure what you mean by "section" of Python, but there are some popular Python web development frameworks, notably Flask and Django.

Well, not necessarily. It's fine if it's related to something you're doing in Python. But, for example, talking about using nodejs to run a webapp or use js to make a chrome extension are not really on topic here

@topaz widget my bad for all of the questions. One last thing I was wondering, a user on a website (made by html) inputs data. Would it need python to get pushed to the database?

topaz widget Sep 18, 2020, 2:28 AM

#

@plucky tapir You've got a lot to learn. First of all, all websites with user interfaces use HTML on the front-end. HTML gives different elements on a webpage their special meaning. One such element that has special meaning is called a <form> element. This form element is how users submit data from a web page to the back-end for something like Flask or Django to enter into the database. In answer to the other question, Python, or more specifically a framework like Flask or Django, would have some protocols for entering that data into the database. So, essentially you're correct, but there is a lot more to it. Anyway, I'm happy to answer questions, but a new episode of "The Boys" just dropped, so I'm going to log off Discord for now. Keep asking questions. That's the right approach.

@versed python I try and batch as much as possible.

topaz widget Sep 18, 2020, 3:26 AM

#

@versed python 20 requests for a page (with all the content) is not too much. I'm not sure this is something to be concerned about unless your application feels laggy.

#

I think you'll know when you're asking too much from your application.

tepid lark Sep 18, 2020, 3:26 AM

#

20 requests for a page isn't bad, unless that number of requests can scale

topaz widget Sep 18, 2020, 3:29 AM

#

There may be ways to combine the page into fewer requests (that's beyond me), which may take out some of the overhead associated with each 'handshake', but I don't think you're anywhere close to having to worry about that.

@topaz widget @tepid lark thanks for your insights. However you mentioned "batching". What is that? Can you explain it a bit or provide some links?

vestal hound Sep 18, 2020, 5:39 AM

#

Django Rest Framework: How many requests is too many?

I have a page on my frontend which shows 10 Posts. Each of them is associated with multiple Tags and Images. And all this data needs to be fetched from multiple different views. So when I load up this page in my browser about 20 requests are made to my backend. Is this normal/okay?

If it isn't, then what can I do to minimize them?

I am using Vuejs as my frontend if that matters.
@versed python are you making one request per instance?

#

why can’t you fetch everything you need together?

topaz widget Sep 18, 2020, 5:40 AM

#

Good point, as it's an API

vestal hound Sep 18, 2020, 5:40 AM

#

20 requests seens to imply at least 20 queries.

topaz widget Sep 18, 2020, 5:40 AM

#

It should all just come as one JSON string.

vestal hound Sep 18, 2020, 5:40 AM

#

and yeah, if that can scale you will probably have a problem down the road

topaz widget Sep 18, 2020, 5:41 AM

#

How so? @vestal hound

vestal hound Sep 18, 2020, 5:41 AM

#

How so? @vestal hound
@topaz widget I mean, that number of queries

#

like N+1

#

not what you said about JSON

topaz widget Sep 18, 2020, 5:42 AM

#

Oh, okay. Yeah, I mean, 20 isn't terrible for an entire page including media, though, is it? @vestal hound

#

Granted, I don't use DRF, but I see the requests using Django in the standard manner, and it can be quite a few if there are a lot of pictures.

vestal hound Sep 18, 2020, 5:44 AM

#

well

#

I took it as 20 on initial load for just data (like models)

#

which would be a huge lot

#

if it’s 20 over time due to scrolling or something + including one per image + fetching other stuff separately

#

then I would say it’s fine

topaz widget Sep 18, 2020, 5:45 AM

#

So you're talking about AJAX calls?

vestal hound Sep 18, 2020, 5:45 AM

#

yup, basically

topaz widget Sep 18, 2020, 5:45 AM

#

I mean, I guess it's all AJAX with an SPA

vestal hound Sep 18, 2020, 5:46 AM

#

although

#

yeah, that

topaz widget Sep 18, 2020, 5:46 AM

#

Wait, you mean, it's all AJAX?
Always has been.

#

lol

versed python Sep 18, 2020, 5:50 AM

#

I don't really know how to do that

#

why can’t you fetch everything you need together?
@vestal hound this I mean

#

I am limited by my serializers and since I am using viewsets a lot, that also means I have to send requests to different paths of drf

#

Is there a better way?

vestal hound Sep 18, 2020, 5:51 AM

#

I am limited by my serializers and since I am using viewsets a lot, that also means I have to send requests to different paths of drf
@versed python oh

well

#

that's why I guess

#

that's probably what you want

versed python Sep 18, 2020, 5:52 AM

#

can I do something about it?

vestal hound Sep 18, 2020, 5:52 AM

yes

#

you need to modify your serializers

@versed python I found it to be horribly hard to read and extend, and recommend ariadne instead.

vestal hound Sep 18, 2020, 5:55 AM

#

so say you have this, right

#

each song has an artist, and each artist has multiple songs

lethal orbit Sep 18, 2020, 5:56 AM

But GraphQL as a whole makes it very easy to fetch all the data in one query.

GraphQL is more foreign but (I would say) more powerful

Which one is better?

there's no "better"

#

But GraphQL as a whole makes it very easy to fetch all the data in one query.
@lethal orbit This does make it seem "better"

vestal hound Sep 18, 2020, 5:58 AM

#

REST as a style

#

is honestly quite foreign

#

to most people

#

so one tends to end up writing RPC code

#

which is fine, but not REST

versed python Sep 18, 2020, 5:58 AM

#

Yeah it is difficult I must say

#

RPC Code?

vestal hound Sep 18, 2020, 5:58 AM

#

so I guess what you got was something like

lethal orbit Sep 18, 2020, 5:58 AM

#

GraphQL is more modern and powerful. REST has been around forever, and many jobs still expect it. I wouldn't use it in a new project, tbh.

vestal hound Sep 18, 2020, 5:59 AM

#

{'name': 'some_artist', 'date_of_birth': '1963-03-05', 'songs': [1, 8, 34, 494, 2395]} from your serialized Artist

@vestal hound Yeah go on

vestal hound Sep 18, 2020, 5:59 AM

#

and quite unintuitive

#

@vestal hound Yeah go on
@versed python and then

lethal orbit Sep 18, 2020, 5:59 AM

#

I have used both, yes 🙂

vestal hound Sep 18, 2020, 5:59 AM

#

you probably loop through those song IDs

lethal orbit Sep 18, 2020, 5:59 AM

#

DRF was an older project haha

versed python Sep 18, 2020, 5:59 AM

#

class Song:
    artist = models.ForeignKey(Artist, related_name='songs', delete=models.CASCADE)
    name = models.TextField()
    lyrics = models.TextField()

class Artist:
    name = models.TextField()
    date_of_birth = models.DateField()

@vestal hound (For reference)

vestal hound Sep 18, 2020, 6:00 AM

#

and get songs one by one and put them into the SongSerializer

#

but you can also do this

#

class ArtistSerializer(serializers.ModelSerializer):
    songs = ...a custom serializer for a queryset of songs...
    ...your other fields...

    class Meta:
        model = Artist
        fields = ['songs', 'name', 'date_of_birth']

#

so that when you serialize your Artist, it becomes a nested JSON

versed python Sep 18, 2020, 6:01 AM

#

oh wow

#

So thats like HyperLinkedModelSerializer but cooler?

vestal hound Sep 18, 2020, 6:02 AM

#

like:

{
  'name': 'some_artist', 
  'date_of_birth': '1963-03-05',
  'songs': [
    {
      'id': 1,
      'name': 'some_song'
      ...
]}

#

yes

versed python Sep 18, 2020, 6:02 AM

#

Great

vestal hound Sep 18, 2020, 6:02 AM

#

HyperLinkedModelSerializer basically returns a URL saying "go here for more details about this resource"

versed python Sep 18, 2020, 6:02 AM

#

that doesn't look too difficult to implement

you will start fighting the framework

vestal hound Sep 18, 2020, 6:05 AM

you don't have to follow it

#

you can just write an RPC API

#

so basically like

#

think of your application as a Python module

#

and each view as a function in it.

#

that is fine.

#

REST is a different way of thinking about APIs

#

in terms of resources

#

and operations on them

#

and it's really a bit technical and after a while you'll start thinking "why must hypermedia be the engine of application state" etc. etc.

@lethal orbit I think one drawback of using GraphQL with Relational Database is that you can't optimize the database queries anymore, unless there is a way that I'm unaware of

lethal orbit Sep 18, 2020, 6:29 AM

#

Optimize how?

marble carbon Sep 18, 2020, 6:30 AM

#

okay let's say in a given serializer, I know that I'll be providing so and so foreign key data, so I'll be using joins to return those values from the View.

#

but in GraphQL, the user can query whatever the fields and data they like

lethal orbit Sep 18, 2020, 6:32 AM

#

If you have data with joins (foreign keys, many to many), you can still use prefetch or select related in your query, and add that field as a resolver...

#

If you have data with joins (foreign keys, many to many), you can still use prefetch or select related in your query, and add that field as a resolver...
@lethal orbit which is equally necessary in all cases, anyway

#

it's not a problem particular to GraphQL

marble carbon Sep 18, 2020, 6:34 AM

#

so I'll be writing cases in my view that'll check whether the given field is present in query sent by the client and create joins in those scenarios only?

Hello, this is useful in django:

meaning i need to go deeper into model, return field that I want, how do I do that?

@maiden kraken That is another method of describing an FK. This way, as you can see in Post.author, i don't have to import the CustomUser model. Django can figure out what model you are referncing to by itself. this is a better way imo.

#

you can reference another model by '<app-name>.<model-name>' or just '<model-name>' if your models are uniquely named (which they should be).

oh this tool

#

is good, but too slow

strange briar Sep 18, 2020, 11:43 AM

#

yes way too slow

marble carbon Sep 18, 2020, 11:43 AM

#

but like you'd usually just use it on the registration form

#

so 5 secs at max?

strange briar Sep 18, 2020, 11:44 AM

#

yea but i can't let a user wait 4-5 secs on registration form

marble carbon Sep 18, 2020, 11:44 AM

#

hmm, use ajax

#

validate the email on blur

strange briar Sep 18, 2020, 11:48 AM

#

so this must be done via front-end in your opinion ?

marble carbon Sep 18, 2020, 11:52 AM

I mean r u using flask?

or django?

there is any easy way about this ? 😄

marsh canyon Sep 18, 2020, 12:58 PM

#

can't think of any

#

its fine to have logic in the navbar section tho

#

https://openfolder.sh/django-keeping-logic-out-of-templates-and-views

Django: Keeping logic out of templates (and views) - Open Folder

When I first started dabbling with Django and web-development, a good friend with a little more experience advised that I should keep

#

but u should try to implement logic in view mostly

#

in ur case, u can't really do that inside the view, hence in the template

anyways to implement a faster verification ? or should i just use regex
@strange briar Do you need to verify the email exists? Then this is your best bet. Otherwise use with check_mx=False it will be pretty okat

#

Oh wait, i just checked. Turns out I don't use this library at all @strange briar I use validate-email. pip install validate-email

strange briar Sep 18, 2020, 1:27 PM

#

yea i checked your implementation too and validate-email is not up to date, it doesn't use py3dns

versed python Sep 18, 2020, 1:27 PM

#

https://pypi.org/project/validate_email/

PyPI

validate_email

Validate_email verify if an email address is valid and really exists.

strange briar Sep 18, 2020, 1:28 PM

#

so the alternative is to use this

#

https://pypi.org/project/py3-validate-email/

PyPI

py3-validate-email

Email validator with regex, blacklisted domains and SMTP checking.

#

pretty much the same as the previous one

#

they all do the same job but the speed remains the same

versed python Sep 18, 2020, 1:28 PM

#

it does implement pydns

strange briar Sep 18, 2020, 1:28 PM

#

it display an error if you use the check_mx

#

you didn't implemented it so you didn't see it but i did

#

it's default to False

versed python Sep 18, 2020, 1:29 PM

#

yes I do remember that

#

@marble carbon i'm using django

marble carbon Sep 18, 2020, 1:31 PM

#

oh well, you can write a custom endpoint that accepts an email and return its validity only 8n json response, and then you can call it from ajax on your page

strange briar Sep 18, 2020, 1:49 PM

i know about asserts

#

the way i implemented it following you is that i create an object

#

i keep this object and then i reference it directly

#

what i want to do is create this user

#

and then directly reference it on test_valid_customers via the db

#

i have to use something like this

#

def test_departures_count(self):
a = Airport.objects.get(code="AAA")
self.assertEqual(a.departures.count(), 3)

#

not repeat self

I have one problem that is failing to be googled out. I have a django website and I'm working on its SEO, so atm I'm doing everything to make the website faster, and my last step is implementing CDN. Cloudflare is strongly recommended but I can't accept it for privacy reasons, as it is a man in the middle, having all user data flow in plain text on their servers. I don't think they really do anything bad with the data, but using it would require GDPR box appearing and user accepting it, which I don't want to force him to do. Is it possible to use some CDN type solution to serve static files only? So basically I only care about the speed-up without any other things like ddos protection while protecting user privacy fully.

#

I see a lot of people finding this issue with cdns on reddit, but there are no possible solutions suggested, are there really no alternatives?

lethal orbit Sep 18, 2020, 3:30 PM

#

You can do that fairly easily....

#

You're using Django templates?

#

I don't, but I think you basically have to set the statics settings to point to something like https://cdn.yourdomain.tld and point that to the CDN.

#

frosty abyss Sep 18, 2020, 3:40 PM

#

Really, that's it? :D

#

So I wouldn't even need to modify references to static files from within templates?

quick question on django

#

i want to somehow make people unable to register usernames with similiar case sensitivity

#

e.g. people cant register as Jake if there already exists JAke

vestal hound Sep 18, 2020, 4:02 PM

#

e.g. people cant register as Jake if there already exists JAke
@bright spindle validator on the username field

bright spindle Sep 18, 2020, 4:02 PM

#

is that the best way

vestal hound Sep 18, 2020, 4:02 PM

#

combined with check constraint at the database level

bright spindle Sep 18, 2020, 4:03 PM

#

would it be the most ideal way

#

i still do want to keep the case sensitive username

#

but i dont want other users to have it

#

e.g. registering Jake allows noone to use JAke and other similiar names

vestal hound Sep 18, 2020, 4:04 PM

#

actually, no, wrong constraint

#

not a check constraint, a unique constraint

bright spindle Sep 18, 2020, 4:04 PM

#

however logging in allows Jake to type in JAke, and it will always be displayed as Jake

frosty abyss Sep 18, 2020, 4:05 PM

#

With validator, as gm wrote, you can write whatever python function

vestal hound Sep 18, 2020, 4:05 PM

#

however logging in allows Jake to type in JAke, and it will always be displayed as Jake
@bright spindle that's a presentation layer concern

bright spindle Sep 18, 2020, 4:05 PM

#

is there any documentation to lead me the way

vestal hound Sep 18, 2020, 4:05 PM

#

not a check constraint, a unique constraint
@vestal hound this is a bit complex though

#

so you should probably go wit hthe validator

#

it's not perfect

#

but it's a lot easier.

#

in general you want to enforce this kind of restriction as deep as possible

bright spindle Sep 18, 2020, 4:06 PM

#

arent unique constraints very strict

vestal hound Sep 18, 2020, 4:06 PM

#

and you can't go deeper than the database

bright spindle Sep 18, 2020, 4:06 PM

#

i know postgresql

vestal hound Sep 18, 2020, 4:06 PM

#

arent unique constraints very strict
@bright spindle yes, a case-insensitive unique constraint on username

frosty abyss Sep 18, 2020, 4:06 PM

#

Google django custom form validation

bright spindle Sep 18, 2020, 4:07 PM

#

also is it more ideal to store a column with the case sensitive username

#

and let the web handle it

#

or have two columns

#

one case sensitive and one case insensitive

vestal hound Sep 18, 2020, 4:07 PM

#

wait, go back

#

so how do you want them to log in?

#

should logging in be case-insensitive?

bright spindle Sep 18, 2020, 4:08 PM

#

case sensitive

#

but the username should never be used no matter the case sensitiveness

vestal hound Sep 18, 2020, 4:08 PM

#

huh

bright spindle Sep 18, 2020, 4:08 PM

#

an username e.g. Jake

vestal hound Sep 18, 2020, 4:08 PM

#

so which is it

#

I'm not talking about

#

tat

#

that

#

I mean

#

solely when logging in

bright spindle Sep 18, 2020, 4:09 PM

#

case insensitive

vestal hound Sep 18, 2020, 4:09 PM

#

then

#

why don't you just store

#

the lowercase version

#

always

#

and have a unique constraint on that

bright spindle Sep 18, 2020, 4:10 PM

I'm creating a test application using Flask on Python3.8.3, and it correctly receives my post request data, and my post request data is correctly being sent, but request.form is always empty, can someone explain why? (I'll link my code below.)

#

CODE: ```py
def WebMain(q):
from flask import Flask, request, make_response
web = Flask(name)

def GetFile(file):
    try:
        with open(file,"rb") as f:
            data = f.read()
            f.close()
            return make_response(data)
    except FileNotFoundError: return make_response("")

@web.route("/")
@web.route("/index.html")
def index(): return GetFile("index.html")

@web.route("/favicon.ico")
def favicon():
    response = GetFile("favicon.ico")
    response.mimetype = "image/x-icon"
    return response

@web.route("/background.png")
def background():
    response = GetFile("background.png")
    response.mimetype = "image/png"
    return response

@web.route("/verify.html", methods=["GET","POST"])
def verify():
    if request.method=="POST":
        print(request.form)
        return "Yes"
    else: return GetFile("verify.html")

print("Website has loaded!")
web.run()```

#

(Also the reason it's wrapped in a function is because I'm using multiprocessing.Process to run it and I'm importing it inside another script)

#

Console Output: ImmutableMultiDict([]) 127.0.0.1 - - [19/Sep/2020 12:53:04] "POST /verify.html HTTP/1.1" 200 -

#

(I'm only using requests.post because it's easier to test that way, in reality it's being sent by a browser)

Hello

fringe osprey Sep 19, 2020, 3:43 AM

#

To whoever asked that unrelated question earlier, here's how I'd do it: py def MassDelete(s, c): if len(c): return MassDelete(s.replace(c.pop(), ""), c) else: return s

>>> MassDelete("ABCDEFGHIJ",["A","C","D","J"])
'BEFGHI'```

warped timber Sep 19, 2020, 4:47 AM

#

@fringe osprey str.translate is much more efficient

#

only needs 1 loop instead of n loops

#

where n== number of chars

lethal orbit Sep 19, 2020, 5:17 AM

#

I'd just do return "".join(_ for _ in s if _ not in c) or similar.

#

If c is a set instead of a list, even better.

I am not sure if this fits under this category its websites and database stuff but I have a wordpress website and I just wanted to know if their is a way to modify documents in mongoDB from my wordpress website through like html code or a button or something?

tepid lark Sep 19, 2020, 6:16 AM

#

Wordpress is bound to mysql

cold socket Sep 19, 2020, 6:17 AM

Hey all I have a Flask app that uses Redis for task queuing and React in the front end. I am running all in a development environment on my macbook. I really want to deploy this to a VPS on like DigitalOcean/Linode. What is the simplest/most efficient way to deploy it?

lethal orbit Sep 19, 2020, 6:17 AM

#

There may be plugins for mongo with WP? I wouldn't know though, I haven't used that in years.

#

@cold socket docker-compose

tepid lark Sep 19, 2020, 6:18 AM

#

Yeah docker is the way to go

native tide Sep 19, 2020, 6:18 AM

#

no I check their are none unfortunately, I just prefer mongoDB as it is non SQL but...

lethal orbit Sep 19, 2020, 6:19 AM

#

Then you can write your own.... or use something in python lol

cold socket Sep 19, 2020, 6:19 AM

#

So I am hosting all my code on GitHub. When I need to push out an update does Docker integrate with Git some how?

outer apex Sep 19, 2020, 6:19 AM

#

@fringe osprey to get JSON data from the request, you'd use request.json

lethal orbit Sep 19, 2020, 6:20 AM

#

So I am hosting all my code on GitHub. When I need to push out an update does Docker integrate with Git some how?
You can use github actions to automatically build your containers, and deploy on push.

cold socket Sep 19, 2020, 6:20 AM

#

So I don't have to build the docker image locally? I can just build it based off my repo?

lethal orbit Sep 19, 2020, 6:21 AM

#

I use gitlab-runner with Gitlab.... it's defined in a yaml file. Github actions will be a bit different, but similar. https://gitlab.com/patryk.tech/patryk.tech/-/blob/master/.gitlab-ci.yml

tepid lark Sep 19, 2020, 6:21 AM

#

No, but you do need somewhere to store it

lethal orbit Sep 19, 2020, 6:22 AM

#

You don't have to build it locally, but I do like a consistent flow, so I use docker for dev and for deployment.

tepid lark Sep 19, 2020, 6:22 AM

#

github action to push to DO container registry and pull from there

lethal orbit Sep 19, 2020, 6:22 AM

#

No, but you do need somewhere to store it
Not necessarily. You can just build it on the VPS and bring it up, no need to push it anywhere.

cold socket Sep 19, 2020, 6:23 AM

#

Interesting, so when you start developing something in dev do you start with a container and develop in there?

tepid lark Sep 19, 2020, 6:23 AM

#

yeah but that's harder to integrate with your CI

lethal orbit Sep 19, 2020, 6:23 AM

#

Yeah, I do.

#

yeah but that's harder to integrate with your CI
What? How?

#

Literally the same except minus the push lol

cold socket Sep 19, 2020, 6:24 AM

#

Ok good to know. I'll need to research some tutorials on containerizing Flask w/ Redis.

#

Thank you guys for the help!

lethal orbit Sep 19, 2020, 6:25 AM

#

#tools-and-devops is a good place to talk about docker and CI/CD 🙂

tepid lark Sep 19, 2020, 6:25 AM

#

I hadn't considered doing actions on your VPS as part of that

#

code goes in, artifact comes out

I am trying to run a flask application on Windows. I keep getting the error

Error: Could not locate a Flask application. You did not provide the "FLASK_APP" environment variable, and a "wsgi.py" or "app.py" module was not found in the current directory.

I have tried both set FLASK_APP=main.py and $env:FLASK_APP=.\main.py, but it just refuses to run. Can anyone help

cold socket Sep 19, 2020, 6:26 AM

#

@lethal orbit Thank you!

#

@merry geode I recommend using python-dotenv

warped timber Sep 19, 2020, 6:26 AM

#

check if the file is actually in your cwd

merry geode Sep 19, 2020, 6:26 AM

#

I am using virtualenv as of now. Does that make a difference?

warped timber Sep 19, 2020, 6:26 AM

#

no

merry geode Sep 19, 2020, 6:26 AM

#

@warped timber yes, it is

cold socket Sep 19, 2020, 6:27 AM

#

@merry geode Nah its different. Install it using pip install python-dotenv and then create a .env file in the root

warped timber Sep 19, 2020, 6:27 AM

#

no

#

You don't need to

cold socket Sep 19, 2020, 6:27 AM

#

It'll make managing your environment variables much easier

@merry geode did you check if the variable is actually set?

#

@fringe osprey to get JSON data from the request, you'd use request.json
@outer apex Thanks

vestal hound Sep 19, 2020, 6:28 AM

#

like, in the first line of your script, import os; print(os.environ['FLASK_APP'])

#

#

idk

merry geode Sep 19, 2020, 6:28 AM

#

@vestal hound doesn't seem to have been set

#

I get a KeyError on running that command

lethal orbit Sep 19, 2020, 6:29 AM

#

Try forward slashes...

#

~~windows is dumb~~

vestal hound Sep 19, 2020, 6:29 AM

#

I don't really remember how to set environment vars on Windows

#

but, yeah, that's why you have a problem

merry geode Sep 19, 2020, 6:30 AM

#

~~windows is dumb~~
@lethal orbit From a development perspective, totally agree

lethal orbit Sep 19, 2020, 6:30 AM

#

Using \ is usually a bad idea.

merry geode Sep 19, 2020, 6:30 AM

#

But then, Flask is also dumb

lethal orbit Sep 19, 2020, 6:30 AM

#

lol, yeah. I have struggled a lot with that same error even on Linux.

outer apex Sep 19, 2020, 6:30 AM

#

@merry geode if main.py is in the root of the directory, you can ignore the .py extension

merry geode Sep 19, 2020, 6:31 AM

#

Nope, forward slash also doesn't make a difference

outer apex Sep 19, 2020, 6:31 AM

#

on Linux, it's export FLASK_APP=main

cold socket Sep 19, 2020, 6:31 AM

#

I'm telling you creating that .env file in the root will help you with your headaches

outer apex Sep 19, 2020, 6:31 AM

#

I can't remember what the export equivalent is for Windows

merry geode Sep 19, 2020, 6:31 AM

#

The windows equivalent is set

#

But it's not working

#

I'll try dotenv

cold socket Sep 19, 2020, 6:32 AM

#

@merry geode https://pypi.org/project/python-dotenv/

PyPI

python-dotenv

Add .env support to your django/flask apps in development and deployments

vestal hound Sep 19, 2020, 6:32 AM

#

The windows equivalent is set
@merry geode probably syntax is wrong

cold socket Sep 19, 2020, 6:32 AM

#

Are you on Windows 10 btw?

merry geode Sep 19, 2020, 6:35 AM

#

@merry geode probably syntax is wrong
@vestal hound not getting any errors on running that command. It runs fine.
Also, I found it on a Flask tutorial itself

#

@cold socket Yes, Windows 10.
So I have .env file and I have put FLASK_APP=main.py in it. Now how to I use it

vestal hound Sep 19, 2020, 6:36 AM

#

@vestal hound not getting any errors on running that command. It runs fine.
Also, I found it on a Flask tutorial itself
@merry geode in the sense that it's not setting the right thing

merry geode Sep 19, 2020, 6:36 AM

#

OK, got it. It ran, thank god. I needed to write python -m flask run instead of just flask run.

#

Thanks!

cold socket Sep 19, 2020, 6:39 AM

#

@merry geode I usually put these two lines in there FLASK_APP=app.py FLASK_ENV=development

#

And flask run always works

merry geode Sep 19, 2020, 6:40 AM

#

BTW, I was trying to use FastAPI at first. But some library called orjson just refused to get installed.
First it threw some error which got resolved by switching to Python 64-bit. Then it threw another error which should have gotten resolved by installing rustup, but got resolved only after selecting the nightly build of cargo or whatever. But then it threw a new error, at which point I just got frustrated and switched to Flask

cold socket Sep 19, 2020, 6:40 AM

#

Also I believe with Windows when you use "set" that only stores the environment variable temporarily. So if you start a new session you have to set it again.

merry geode Sep 19, 2020, 6:41 AM

#

And flask run always works
@cold socket I think there's some issue with my installation where flask run tries to run it with 32-bit Python and hence fails, but when I put python -m flask run, it finds the right interpreter

cold socket Sep 19, 2020, 6:42 AM

#

@merry geode That's unfortunate. I was actually looking to make the transition to FastAPI but ill wait till it matures a bit more.

merry geode Sep 19, 2020, 6:42 AM

#

Oh, no. Actually, after putting the .env file, even flask run is working. That's great. Thanks @cold socket

cold socket Sep 19, 2020, 6:43 AM

#

@merry geode That's interesting. Yeah I stopped using Windows completely since I switched to my mac. But glad to hear its working.

warped timber Sep 19, 2020, 6:43 AM

#

what about the thing its built on?

#

I think starlette?

merry geode Sep 19, 2020, 6:44 AM

#

Actually, I had run FastAPI in the past myself. But at that time (actually, just 4-5 months ago) I was very new to web dev and Django just felt easier to get started with. I was not familiar enough to set up the entire project the way FastAPI and Flask require.
Now that I understand things a lot better, I thought I'll try it out, but for some reason now I'm not able to run FastAPI. Don't know what changed in that time.

#

I think starlette?
@warped timber hadn't heard of it. might give it a try

gleaming thunder Sep 19, 2020, 9:04 AM

#

Right so, what's your current set up right now?

#

Cool, have you set up Gunicorn/uWSGI yet?

#

It is, yes, though you'll have to set up those two things and configure Apache first

#

So basically, you know how like, Flask comes with this development server that basically allows you to check out what you're currently working on locally?

#

Basically you'd want to configure Apache so that domain.com/foo routes into your Flask app instead

#

Unfortunately I've only actually used nginx for my Django app so I'm not really familiar with the configuration

#

DigitalOcean seems to have an article about Flask and Apache, you might want to look around though
https://www.digitalocean.com/community/tutorials/how-to-deploy-a-flask-application-on-an-ubuntu-vps

#

Right, that's as far as I can go in terms of Apache, again, I'm not as familiar with it as I'm familiar with nginx

#

You could try routing

lethal orbit Sep 19, 2020, 9:22 AM

#

You should use mod_wsgi for Apache

@native tide you can just follow that example. Put your flask directory in that Directory directive.

Nope?

That's what Directory directives are for 😄

If your site is at /var/www and your flask app is /var/www/flask, you can just add a Directory /var/www/flask section

Yeah

Django: How do I unlink images that were uploaded to my disk? Suppose I delete an object of PostImage, how do I delete the actual image.png that would be stored in the disk?

#

Do I have to do that manually?

lethal orbit Sep 19, 2020, 9:44 AM

#

Note that when a model is deleted, related files are not deleted. If you need to cleanup orphaned files, you’ll need to handle it yourself (for instance, with a custom management command that can be run manually or scheduled to run periodically via e.g. cron).

#

Maybe handle it in the pre_delete signal?

versed python Sep 19, 2020, 9:45 AM

#

That kinda sucks

#

but I see how that would be useful

#

Maybe I will have to write a py script to recurse over the directories and delete unlinked files

should i design the api first or plan the react front end before that?

lethal orbit Sep 19, 2020, 10:13 AM

#

Iterate and do both at once 😄

#

I usually just add a basic page, with fake data on the front-end. Then add an API call.

rancid lintel Sep 19, 2020, 10:14 AM

#

Iterate and do both at once 😄
@lethal orbit expected easier answer lol

lethal orbit Sep 19, 2020, 10:15 AM

#

Hook up the front-end to the back-end, then work on another feature.

#

You don't need to spend too much time ~~over~~designing an API ahead of time.

#

Sometimes I do it the other way around.

#

You can just call the API using curl for REST, or graphiql for GraphQL. It really doesn't matter.

#

(yes, there are tons of other options I didn't bother listing).

rancid lintel Sep 19, 2020, 10:30 AM

@lethal orbit nice man thanks.

@lethal orbit In my var/www/domain.com/flaskapp what files should I have for example for a hellp world program?
@native tide I don't really use Flask, and never have with apache, but I think you need one file for your app, and one .wsgi file.

lethal orbit Sep 19, 2020, 11:11 AM

#

Are you on the same machine as Flask?

#

127.0.0.1 is localhost

#

Then you can't use Firefox.

#

127.0.0.1 is your machine.

#

You can use curl on the server.

#

curl http://locahost:5000 should work, if you open a new SSH section

#

No, it's not bound to the public IP

#

On the loopback interface 😄

#

* Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

#

flask run --host=0.0.0.0

#

or use app.run(host= '0.0.0.0')

#

You need to bind to the public IP.

#

0.0.0.0 binds to all available interfaces.
