[rocky ferry]

?

[arctic wraith]

you give a specific name to your function views

and you can just call the view on your html code using {% url %}

oh i forgot , href="{% url 'your_name' %}"

[arctic wraith]

your urls ?

did you add the name

[rocky ferry]

yes

[arctic wraith]

no not here

[rocky ferry]

then

[arctic wraith]

just in urls.py

delete what you've done here in views

don't change your views , put just the attribute name in your urls

[rocky ferry]

yeah it is working

[arctic wraith]

okey

[rocky ferry]

but why still

i get this error bro

[arctic wraith]

try to work with name in both of your apps

[rocky ferry]

do i need to put name in project url.py

also

[arctic wraith]

yeah

work with {% url %} it's better

[rocky ferry]

can u please explain me how in backend it is working

[arctic wraith]

it is a way to add a link to another one of your pages in the template. url tells the template to look in the URLs.py file, and it changes dynamically

[rocky ferry]

wow

i have added but still it shows me this error bro 😦

[arctic wraith]

it tells the template to look for something with name=(name of the url)

[arctic wraith]

no not here , it's not necessary

in your 2 apps

[rocky ferry]

but when i open my server it is throwing me error

how can i overcome it

[arctic wraith]

you added the name at app register ?

[rocky ferry]

yes

[arctic wraith]

remove this one

add your names at the second app

[rocky ferry]

i did still same error

[rocky ferry]

i did brother

[arctic wraith]

show your html

[rocky ferry]

when i click on register it working

but the problem is when i open local host it is throwing me error

[arctic wraith]

did you change all your a href ?

[rocky ferry]

i'm using it only for one bro

currenctly working for one register thing

[arctic wraith]

change it for all

[rocky ferry]

actually i'm using template

[arctic wraith]

it's better to work like this

[rocky ferry]

so i got to use {% static %}

[arctic wraith]

yeah {% load static %}

work with python code in your html

[rocky ferry]

yeah i'm using that to render the static files

it works fine

but when i added register it got messed up

!pastebin

[arctic wraith]

https://www.geeksforgeeks.org/url-django-template-tag/

look at this one , you will understand

[rocky ferry]

yeah i saw it

so basically , since i'm using rendering 2ndapp stuff from 1st app

i need to use this syntax

[arctic wraith]

yeah

[rocky ferry]

i removed other navbars

but still same error

[rocky ferry]

what should i give for empty anchor tag

like <li><a href="#"><i class="fa fa-pinterest" aria-hidden="true"></i></a></li>

[arctic wraith]

yes you can leave this one

[rocky ferry]

then why it is showing me error on local host

😦

[arctic wraith]

it shows error at your fist page ?

for the others no ?

[rocky ferry]

first page bro

[arctic wraith]

what is the first page , i mean url and view

[turbid mirage]

I have a model with a many-to-many relationship. The relationship is between 'User' and 'Movie'. The Movie model contains the many-to-many and has a related name: "users_liked". When I create a movie it should always default to "Liked" by the User. In the template, I will have an if condition to check if it is liked or not liked and return a thumbs up or down. Right now this is what is returned: 'movie_review_app.User.None`. It is the name of the app plus the name of User model and then None. I really do not understand this. When I add a movie it is always False. I can send a couple screen shots of HTML, Model and Views.

[rocky ferry]

localhost

[rocky ferry]

this one

[arctic wraith]

it didn't find the template

probably your url

not the correct one

check your url please

[versed python]

How are you creating the movie object?

I assume youre using Django?

[turbid mirage]

Yes

[rocky ferry]

from django.urls import path,include

urlpatterns = [
    path('admin/', admin.site.urls),
    path("",include('travello.urls')),
    path("",include('register.urls',)),
    #path("hello/",include('calc.urls')),
    
]

this is my url

[versed python]

You have two urls at the same path

[turbid mirage]

This is how I am creating the movie when added within the views.py

[arctic wraith]

did you work with signals ?

[versed python]

You'll have to call save i think after add

[turbid mirage]

I do not think so. Not sure what signals is.

[rocky ferry]

    path('admin/', admin.site.urls),
    path("",include('travello.urls')),
    path("/register",include('register.urls',)),
    #path("hello/",include('calc.urls')),
    
]

i changed url

but still same

[versed python]

Signals would be a better use case here, yes

[versed python]

Could you send the code directly?

[arctic wraith]

yes to automatically saves changes

[versed python]

Show contents of register/urls.py

[arctic wraith]

show me your travello urls

your index is in travello right ?

[rocky ferry]

from django.urls import path,include

urlpatterns = [
    path('admin/', admin.site.urls),
    path("",include('travello.urls')),
    path("/register",include('register.urls',)),
    #path("hello/",include('calc.urls')),
    
]

[turbid mirage]

I can give you GitHub. Would that be better?

[rocky ferry]

yes

[versed python]

Yeah dm it to me. I gtg now

[rocky ferry]

May be I should use static

In href

The WebSocket transport is not available, you must install a websocket server that is compatible with your async mode to enable it```
 I get this error when trying to start a flask server socketio and make a connection from my reactjs frontend

Any clue why?

[elder forge]

say i want to take an upload from the user then do some action on the file and return it to the users
which storage service is the best for it. I don't want to save the file for longer may 15 mins max
which storage service can give me this any idea anyone.

[versed python]

hacky but you can use heroku since its free tier will take care of cleaning up the files for you.

[rocky ferry]

@versed python

can u please help me

[versed python]

whats the problem?

[rocky ferry]

path problem bro 😦

[versed python]

why are you trying to access /home? it clearly does not exist

[rocky ferry]

from django.urls import path,include

urlpatterns = [
    path('admin/', admin.site.urls),
    path("travello",include('travello.urls')),
    path("register/",include('register.urls',)),
    
    
]```

[versed python]

you forgot at the end / in travello

[rocky ferry]

yeah ur right , i have one question bro it is not possible to put empty path

for by default

like a landing page or home page

?

[versed python]

yes it is

path("", view_func, name="landing_page")

[rocky ferry]

i can put it in any template folder of any app

will it work

[versed python]

no only the main urls.py

[versed python]

this one

[rocky ferry]

u mean only in project url

i can write a view and call it there

[turbid mirage]

@near ocean If you are in you project urls you can have empty path

[rocky ferry]

ok

thank u so much guys

@versed python

[rocky ferry]

thank u

🙂

[elder forge]

like really....how does it knows what files to delete or should i say how do i program it delete those files
do you have any docs link

[versed python]

it compresses your project source code and anything outside this compressed file gets deleted i think

and no, you can not configure which files would be deleted

another method to solve would be hosting your app on a custom server and running a cron job every x hours to delete the files that are not needed

this would be the better method if you expect the app to actually get serious

[elder forge]

i want to do this only that's why i was thinking of putting the files on remote storage service
how can i do this if you could tell me
it will be truly helpful
i am struck at this for days and ca't find an efficient solution

[versed python]

what do you want me to tell you?

cron jobs are very easy, look up a tutorial

[elder forge]

i just want a hosting platformthat lets me do this
i am using the flask framework.
like if i can do this with heroku i will do it rightway or do you know any hosting platform

[versed python]

ive personally used AWS and digital ocean so it should work there

but any platform that supports linux systems should be able to do this

[native tide]

Can get some tips to get some real client who will ay

I mean pay

[elder forge]

Thank you so much for your help and telling me that it is called cron job.

[native tide]

Cause I have a good experience but can't find a client

[elder warren]

Hi! How do I start making a website? Any useful sites I should rely on? 🙂

[thorn igloo]

go to youtube and learn the basics

[gritty cloud]

The way not to do it is to take shortcuts with things like Bootstrap CSS, or some weirdo no-code solution

Learn it, and learn it right

[opaque rivet]

Bootstrap/tailwindcss are life savers tho

[gritty cloud]

in some cases when you need something fast

[tacit jewel]

Hi, can anyone tell me what’s this feature called in css or bootstrap..

If I have to auto scroll a text (like the stock prices on a business news channel) if the text is getting wrapped.

[rocky ferry]

i don't understand why user is not adding to my database

i did setting.py and

[stark tartan]

i want to show the recent chats in left section of chats i use Django channels for chating but while chating in one group the new messages from other groups are not coming in left section as a recent chats of chat please can you tell me what to do

[native tide]

I think I know the selector on what to do when the text is to big. But idk what you mean with autoscroll edit: Is not a selector but a property, it's overflow: scroll;

[native tide]

deep text conversation

[tacit jewel]

Have you ever noticed on websites when text overflow it start to run from right to left automatically like a gif so the user can read the full text. I am sure I have seen it somewhere.

[native tide]

I don't recall seeing that. Also I'm not frontend pro 😄

[tacit jewel]

Me neither. Trying to figure out the right keyword to Google. Lol

Thanks anyway

[opaque rivet]

@tacit jewel overflow-x: scroll

[tall plaza]

hi i am trying to deploy django api on heroku
i am facing some error
libGL.so.1: cannot open shared object file: No such file or directory

anyone have any idea

about it

[tacit jewel]

Hi, This just adds a scroll bar which user can use to move around and read the text.
I was referring to no scroll bar and text getting moved automatically like a gif from right to left.

[versed python]

Probably one of your dependencies needs a c library to work. Try to find which dependency is it and then see how to install dependencies in heroku

[opaque rivet]

@tacit jewel ah, thanks for the clarification. I think you refer to a marquee:
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/marquee

[tacit jewel]

Although it seems depreciated but it would really helps me find the solution to my problem. Now at least I can Google with the right keyword. Thank you so much.

I would have to use JQuery to only run it when the text is overflowing.

[gritty cloud]

So when you scroll downward it scrolls sideways?

[tacit jewel]

Actually no it’s just supposed to scroll sideways automatically without any scrollbar if the text overflows.
I got my answer actually, I’m supposed to use something like marquee element (since it’s depreciated now).

[hot sandal]

has anyone heard of fast api?

how do y’all feel with fast api vs flask

[rare oar]

I’m using fast api right now in a small project I just started so far it seems fantastic.

Also along that note: any way to mix best of both worlds? I’m using server side rendering and templates for ease. But itd be great if I could inject a component that will fetch an api and display data and not hold up the response. Is that doable? Was thinking it could be easy as injecting react in a small block, but that seems like a lot of overhead.

[rare oar]

this channel moves too fast for me

[tranquil anchor]

does anyone know how to use these variables in bulma?

[merry lotus]

Hey everyone, so I'm learning django and blogging about it simultaneously, so I want to upload it on GitHub. I won't be using this project for production, only as a portfolio item. So considering I'd like someone to be able to run it on their system, is it okay to commit everything, or do I need to hide certain things?

(I'd just like to confirm that nothing inside the django code contains any information about my computer that might help a potential hacker later down the line - - low probability but I'm still just concerned)

Thanks!

[topaz widget]

_ is it okay to commit everything, or do I need to hide certain things? _

If this is going to be a public repository, I would not commit things like secret keys, etc...
By default, the Django configuration file (settings.py) has a secret key in it unless you are importing this as an environment variable or something like that.

[merry lotus]

Yes, I was wondering what to do about that...
Since I'm not gonna deploy this site online, is it okay if I just removed the line of code containing the secret key?

[topaz widget]

You should move the secret key into another file outside of your project folder or set it as an environment variable and import it from there.

I put the secret key into a JSON file and load the JSON to obtain the secret key for the project.

None of my Django code contains the secret key, only references to it.

You may want to put this site online eventually, so I would just get in the habit of moving the secret key to another file and importing it.

[merry lotus]

Yep I'm gonna do that too, I'm actually working on two django projects: the first is a django version of my blog (which is currently built on WordPress) and the second is a portfolio item, so I'm thinking when I deploy my blog I'm gonna move the secret key to a safe place, among other things

Is there anything else that I need to take care of?
I ran the checks, got quite a few things but I'm not sure they're needed at this point...

[topaz widget]

Everything else is up to you, though. Hackers can take a look at your backend code if you put it all up on github, and if it's poorly written, they can still find exploits.

[merry lotus]

My main concern is not the site getting compromised, I hope I'm making that clear

[topaz widget]

What is your main concern then?

[merry lotus]

It's a learning based project, so I'll be uploading the backend code too, and it'll all be accessible to everyone

My concern is the code containing something about my device that could help a hacker

[topaz widget]

Nothing in your github repo should have any information about your device.

[merry lotus]

When I deploy my blog itself, that's when I want to make sure no one can see the backend code

[topaz widget]

Unless you put information about your device in the directory that the git repo is cataloging.

Django is meant to run on a web server, so if you just put your repo at the top level of your Django project, it shouldn't have any information about your device.

I wouldn't worry too much about that, though.

[merry lotus]

Makes sense, I'm just overly cautious about this kinda stuff haha

[topaz widget]

You send information about your device to websites every time you make an HTTP request.

[merry lotus]

Yeah there's that too

[topaz widget]

Have you ever looked at an access log before?

[merry lotus]

I'm quite new to the world of Web development

Not really

[topaz widget]

Okay, well, if you take a look at an access log, it has something called a user-agent string, parameter, what have you. It has information about the browser and the device.

These log entries also have IP address, HTTP status code, time of request, and a little more.

[merry lotus]

Yeah it's just easy to forget, I mean nothing is really hidden to someone who cares to dig deep enough

[topaz widget]

So I wouldn't worry too much about putting out information about your device because you're doing it all the time when you get on the internet.

What I would worry about is putting private information like secret keys out there for anyone to see.

[topaz widget]

User agent strings are only the tip of the iceberg, not really that deep to be honest.

User agent strings can also be spoofed.

which is one reason they're not a great way to identify someone alone.

[gritty cloud]

you have to use sass and declare these variables in your sass file

then import everything you need to build the full css file

these variables define the navbar

[tranquil anchor]

rn im importing bulma like this

[topaz widget]

I once wrote a script for doing web scraping that spoofed the user agent string so they couldn't see I was using Python to access their website.

[gritty cloud]

ya can't do it like that :./

to customize you need the npm package

or if your using Django

[tranquil anchor]

sob

[merry lotus]

Really interesting stuff, thanks man it's all going into my list of things to check out!

[tranquil anchor]

i am

[gritty cloud]

you can use dcjango simple buloma

!pypi django-simple-bulma

[lavish prism]

django-simple-bulma v2.4.0

Django application to add the Bulma CSS framework and its extensions

[topaz widget]

@merry lotus
Here is a log entry from my website:
114.119.142.112 - - [05/Aug/2021:19:47:42 +0000] "GET /robots.txt HTTP/1.1" 404 7047 "-" "Mozilla/5.0 (compatible;PetalBot;+https://webmaster.petalsearch.com/site/petalbot)"

The first number is the IP address.
The next thing in brackets is the time of the request.
Next is the type of request (GET) , the url they were attempting to access (/robots.txt), and then the protocol that was used (HTTP/1.1)

Next is the return code (404 - I don't have a robots.txt file--I should probably add one but I don't care at the moment)

After that, where it says Mozilla/5.0... is the user-agent string.

So it appears that this was a search engine crawling my website (or someone posing as one).

[merry lotus]

Whoa nice, that's really cool!

[topaz widget]

Yeah, that's typically the kind of thing you can see as the admin of a website.

[merry lotus]

Question: my site hasn't been indexed by Google yet, but cloudfare tells me I had like 500 visitors this month, so could you maybe suggest what's going on?

only a couple friends know about it at the moment, so idk how I'm getting that kinda traffic... Unless something is up with that

[topaz widget]

It's spammers and hackers. I think they're getting your domain name from the registry but I'm not sure about that.

Some of the traffic might be search engines, too.

Cloudfare probably has a way for you to see the access logs, and there are services that tell you the origins of IP addresses.

one such site I've used is db-ip.com

If you run an IP address through that database, it has metadata about that IP address.

But just be aware that IP addresses aren't always the best way to identify because requests can be routed through proxies (like a VPN).

If you can see the access logs, you might be able to infer the intent of the requests.

[merry lotus]

Okay...lots of stuff to learn
Could you give me some very basic tips about securing my site? I'm only learning security rn, and I'm doing the best I can, like yesterday I disabled directory listing...but still got lots to do

[topaz widget]

I get requests that are almost certainly hackers trying to break my website.

[merry lotus]

Also I'm trying not to use many plugins

[topaz widget]

When I get a POST request to a url that doesn't exist at my domain (and is a typical admin login url for a wordpress site), it is almost certainly a hacker attempting to get into my backend.

I'm not too familiar with Cloudfare. Do they just do hosting, or do they also have CMS solutions like Wordpress?

Do you have a portal you log into to make changes to your website's content through cloudfare?

[dapper tusk]

cloudflare barely even does hosting

[merry lotus]

Oh I'm only using cloudfare for caching and security, I've hosted my site on bluehost with WordPress

[topaz widget]

Is it like wordpress then?

[dapper tusk]

their main service is a cache and a firewall

[merry lotus]

That's right

[dapper tusk]

they also have static hosting and "not amazon lambda", but few use that

[topaz widget]

I mean, I'm not super familiar with wordpress, but I'd say change the admin login page url to something unique if you can (don't use the default) and pick a strong password.

I see a lot of requests targeting default wordpress urls in my access logs.

I don't use wordpress, though, so it's kind of funny.

[merry lotus]

They're just throwing stuff at the wall and hoping something sticks, then?

[topaz widget]

Other than that, the fewer plugins the better, as those can also be attack surfaces.

[merry lotus]

True, and they slow you down so much

I'm learning django so I can move away from wordpress and take full control of my site

[topaz widget]

Yeah, and they're crawling the entire internet, so they're bound to find someone who has 1234 or some stupid shit like that as their password.

[dapper tusk]

~40% of websites use wordpress, so it is a pretty good attack vector all things considered.
But yes, make sure you don't have default passwords anywhere, ideally have https, keep things up to date

[topaz widget]

Yeah, https is a must.

[topaz widget]

I use Django on my back end.

[dapper tusk]

cloudflare will generally ban suspicious IPs and block their accesses, but it is not perfect and you should not rely on it

[topaz widget]

The web security rabbit hole goes pretty deep. Unless there is big money or sensitive political information involved in your website, you probably don't have to worry about the more complex forms of attack.

@merry lotus Here is a reference for some of the most common security issues facing websites and web applications:
https://owasp.org/www-project-top-ten/

[merry lotus]

Thanks! I'm gonna bookmark this right away and keep strengthening my protections!
I don't think someone would have a lot of incentive hacking my website, but still, this looks fun

[topaz widget]

The people who cast a wide net and take the lazy approach to hacking are the ones you should protect yourself from because petty internet crime is really easy for people to get away with. Fortunately, it is also the easiest form of hacking to counter.

[merry lotus]

Yep,I reckon they'd mostly do it for hijacking hosting room on servers?

[topaz widget]

I can't claim to know their motivations, but I'd say they're probably trying to get people's credit card numbers or things like that.

That's more likely that getting free hosting.

They're just looking for a quick buck.

[merry lotus]

Totally plausible, thankfully I don't have anything like that on my website currently, but I have plans

Man, this thing looks so overwhelming but so fun

[topaz widget]

That seems too complex to manage.

for someone like that.

[merry lotus]

😅 I don't know about that

[topaz widget]

I'm pretty sure they're just looking for sensitive information.

[merry lotus]

Uh so I regularly test my website on places like pagespeed insights, could the unique visitors possibly be those sites?

[topaz widget]

related to finances

I mean, if they're accessing your website, then they would show up in your logs.

[merry lotus]

Looking at visitor demographics, I only have visitors from the US, UK and India. A few in Ireland, China, France. That's it.

[topaz widget]

I find it hard to believe IP addresses are only originating from those places.

I get requests from all over the world.

[merry lotus]

An awful lot of visitors from the UK, I don't even live there lol. Idk if that's a VPN or something because that'd be more evenly distributed?

[topaz widget]

including even Iran

VPN seems like a likely culprit.

I don't know what UK's privacy laws are, but VPN requests often originate from EU countries because the EU has pretty strict privacy laws which makes it harder to pin down the source of requests.

[mint folio]

If your not expecting traffic from there then it’s probably just spam bots. Just follow best practices for server and you should be fine. Also if you have public facing forms you might want to have a honeypot field or captcha to prevent spam submissions.

Anyone have advice on creating a multi user registration form in django?

[ember adder]

The official documentation has all you need and some great examples https://docs.djangoproject.com/en/3.2/topics/db/aggregation/

[ember adder]

What do you mean by multi user form? Form that contains multiple user objects or form that can be accessed by multiple user??

[ember adder]

I am currently developing a Stripe integration feature in Django. I used Stripe API exclusively to process subscription payments, with webhooks to send email. Today I just finished mocking all my API calls to test my payment flow and my views that use the Stripe API. I know exactly the feeling. Congrats!

Hey everyone I've been working on this spotify api app with Django. Today, after a long struggle with deploying onto heroku (static files), for some bizarre reason my app just doesnt work. Attached is a screenshot of the error message. "spotify" is the name of the app. what I find to be completely baffling is the fact that running the django app on localhost works perfectly. any thoughts on how to troubleshoot this weird error?

I have been working on parsing user agents, and I have done fairly well. The one thing that appears to be messing me up a bit is some of the user agents with silk-accelerated=true in them. What exactly does this mean?
Please ping when answering.

[proper hinge]

Looks like it's this https://developer.amazon.com/blogs/post/TxOMW3RNF3FYRK/amazon-silk-tips-for-site-owners

[topaz finch]

ok thanks, I will read through this

[rocky ferry]

can someone please help i don't understand why user is not adding to my database

[rocky ferry]

finally i got the solution

[dusk portal]

@api_view(['DELETE'])
def taskdelete(request,question_id):
    try:
        task=Task.objects.get(id=question_id).delete()
    except Task.DoesNotExist:
        raise Http404(status.HTTP_404_NOT_FOUND)
    return Response(task.data)```

[rocky ferry]

if we are creating template for each app it's better use {% url ' ' %} or else we can use url/url

[dusk portal]

what's the error sir

[dusk portal]

i can't delete my posts

i have a object ft id 8

[dusk portal]

the code

error : ```py

"detail": "Method \"GET\" not allowed."```

postman look

[crisp crane]

def genPrimes(l=[]):
return l.clear() or (l.append(p) or p for p,_ in enumerate(iter(int,1),2) if all(p%i for i in l))
Can anyone help?

trying to understand this piece of code

[worldly garden]

Hello, who could help with docker ? I have this issue

[inland oak]

which database are you using

[worldly garden]

postgresql

[inland oak]

did you check its config, if you made allowed connections others than from localhost(127.0.0.1)?

you do realize that your dockerized application has basically ip 172.18.0.1(or something like that), which is not localhost

[worldly garden]

yes, I made this in django settings: ALLOWED_HOSTS = ['*']

[inland oak]

no

postgresql config

as in

/etc/postgresql/config.cfg

(or some similar address)

[worldly garden]

where I can find postgres config ?

[inland oak]

i have it at the path /etc/postgresql/12/main/postgresql.conf

[inland oak]

are you in linux?

[worldly garden]

nope

win 10

[inland oak]

do you have postgres installed in windows?

[worldly garden]

yes, ah I need to go to the folder with postres ?

[inland oak]

yes

[worldly garden]

ok, one sec

[inland oak]

you need to switch two settings there

postgresql.conf
listen_addresses = '*'

pg_hba.conf
local replication all peer
host replication all 127.0.0.1/32 md5
host replication all ::1/128 md5
host all all ::/0 md5
host all all 0.0.0.0/0 md5

those two changes in two files are enough to allow unrestricted access from any ip

btw, it is quite unsafe for production, so use it for development only

or make sure to have a long password at least

[worldly garden]

I have postgresql.conf.sample

that it ?

[inland oak]

it is... sample, documentation

of the postgresql.conf file

I don't know how it all works in windows, it should be somehow similar I guess

[worldly garden]

ah I found these files

Q: What happens when using celery itself as the broker instead of rabbitMQ?

[inland oak]

https://tekshinobi.com/django-celery-rabbitmq-redis-broker-results-backend/
I think celery will use redis as result-backend and as broker at the same time then

but I am not 100% sure

[worldly garden]

if this method helps me locally, but you say it's unsafe, how I can fix this problem in production?

and no, I have the same problem 😦

[inland oak]

1. restricting to specified list of allowed ips, which have your backend application
   listen_addresses = '*'
   instead of all ips

2. local replication all peer
   host replication all 127.0.0.1/32 md5
   host replication all ::1/128 md5
   host all all ::/0 md5
   host all all 0.0.0.0/0 md5
   Allowing access not for all users

but for specified only one user?

3. making sure allowed user has long password

[wispy quail]

https://blog.miguelgrinberg.com/post/using-celery-with-flask here broker and backend is redis

[worldly garden]

I copied this

[inland oak]

listen_addresses = '*'
this setting will probably have to remain the same though

I mean it sets listening...

[worldly garden]

I'v already have this in settings

[inland oak]

basically we can set only

1. listen to localhost only, if you have database and app at the same server

2. or listening from all ips addresses your server has

so... really permissions you should set only at the level of

only here
local replication all peer
host replication all 127.0.0.1/32 md5
host replication all ::1/128 md5
host all all ::/0 md5
host all all 0.0.0.0/0 md5

here you can specify which user and from which ip addresses can access your db

[worldly garden]

ok, I got the idea, I'll try to manage this problem

thanks

That's fantastic. I have 3 different subscription tier products so once I got the first one done the next was simple enough. Need to a bit more template work for the third since it's a discounted yearly version over the month sub. I'm circling back to webhooks for failed subs tomorrow. But the idea of offloading the credit card processing and storage to Stripe works for me! And yes, seeing all those views/templates automatically updated based on the membership tier level...really cool! Congrats back at ya!

[mint folio]

Well done 👍

[ionic raft]

I was also REALLY impressed with Stripe support. They use Discord for support. I'm going to be using Discord for LanesFlow support. Much easier than building out a forum or Q&A when Discord has the foundation to offload. It was a link on their webpage, I clicked, was in, and navigated to threaded help in less than a minute. Was chatting to a dev and got the final help to make the connection with Stripe

Discord's one-click and you're in...that's my jam right there. Plus, set up a few channels, and can even created dedicated channels for top-tier clients. ideal

[mint folio]

Yeah stripe support, documentation and overall integration is probably one of the best I’ve seen. Especially compare to other gateways like PayPal, which can be a fucking pain.

[ionic raft]

Yeah. My only comment on Stripe for Django...was their documentation had a Flask example but nothing for Django.

[mint folio]

Although PayPal has improved recently I believe

[ionic raft]

It covered Python...However, their Discord support made up for it.

The target market for LanesFlow is business. So PayPal really isn't required for phase 1

Stripe was a must-have tho

[lunar geyser]

hey does somebody know how to use the database models made in django in other scripts that dont really follow the django implementation

[versed python]

There's the peewee package which is kinda similar

[lunar geyser]

ok i will take a look at it

[inland oak]

SQLAlchemy is the most popular choice, but yes peewee and few others alternative solutions exist too

plus... in theory you can just enable django in standlone I guess mode, for its Django ORM being available even in other scripts

at least I managed to do that for celery scripts

and for sphinx docs

it requires just few lines of code I think

[lunar geyser]

ok i guess i will try on the standalone mode so i dont have to rewrite my models

[inland oak]

import django
import os

# Set the default Django settings module for the 'celery' program.
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "core.settings")
# django.setup() # optionally to launch django initialization completely fully with all apps inits

if I am correct, all you need to set this DJANGO_SETTINGS_MODULE variable

plus perhaps django.setup() could be needed in addition

and that's basically it 😉

[lunar geyser]

ok thanks a lot

i will try that out!

👍

[inland oak]

u a welcome.

in Sphinx I made in this way, not sure if ../.. path is really needed being added

import os
import sys
import django
sys.path.insert(0, os.path.abspath('../..'))
os.environ['DJANGO_SETTINGS_MODULE'] = 'core.settings'
django.setup()

[lunar geyser]

i read something that you can register something like this as a django command like python manage.py {commandname}

also as daemon

if i would take something like this as a approach, could i communicate with the django apps in the website from the daemon

[inland oak]

django manage.py commands could be sent from the code directly

instead of using the console version python manage.py something

we can use...

from django.core import management

management.call_command("migrate")
management.call_command(
                "flush",
                "--noinput",
            )

as example to migrate and nulify the data in db

[lunar geyser]

ok but like if i am running a daemon (smth like a discord bot) and i want to tell the bot to react to a change made on the website (like leave a server, etc) how would i do that

[inland oak]

urgh.

[lunar geyser]

but this is still usefull

[inland oak]

that makes additional complexity

if you use discord bot...

it requires it all being async friendly

django ORM is not async friendly

you need to wrap it into something like...

[lunar geyser]

jeah ig now you got my problem

[inland oak]

here is example how i solved it for my discord bot

[lunar geyser]

like i am looking for the right thing before i write smt and realize that that is a bad thing

[inland oak]

as easiest solution I upgraded my python to 3.9

because it has the easiest in built feature to handle it

import asyncio
await asyncio.to_thread(
                self.get_new_forum_records)

self.get_new_forum_records is the name of my sync function

[lunar geyser]

ok that means

[inland oak]

this asyncio.to_thread makes sync code running in alternative thread

in order to have the main thread remaining asynced

in the get_new_forum_records function I make actions like request Django ORM (or in my case used Selenium)

this is important because...

...if you don't do that, discord bot just lags and can't login

because it happens in async background

which would be stuck and busy if you have constant usage of sync code

and bot intreface would be not responsive too

if you use sync code all the time

but this async.to_thread is a work around of it

at the cost of additional parallel CPU usage

not optimal for real production probably, but optimal for home made stuff for sure

[lunar geyser]

hmm ok

like i got what you explained but

that was more like how to start the bot right?

[inland oak]

I used this function in background loop constantly during bot usage

when it was without async.to_thread, the bot was not starting itself because async main thread was busy all the time

and its console interface was not responsive

[inland oak]

it is more how to not disrupt discord bot functionality

when you add any sync code to it

or the bot would basically not start itself at all

[lunar geyser]

ok that is a thing that i would not have noticed on my own. so thanks

[dusk portal]

Ohh

[lunar geyser]

but lets pretend we have a discord bot and a website seperatly
how would i let those two comunicate. So you could push a button on the website and the bot does smt instantly

[dusk portal]

Can someone tell me the whole roadmap
After someone has done django
And rest Framework how can he go to advanced at rest Framework how can he learn Django Channels why he needs to learn Django channels
And resources too

Cez i am ready to give my 101% next 1-2 years

[inland oak]

I'll just bubble anything that comes to my mind about it.
Basically you are looking for message queue pattern

In ideal situation we have master who inits the commands, which are sent to queue like NoSQL database redis
and available worker processes any first taken task

in this situation master would be your website
broker would remain someone like redis
and worker would be your discord bot application

What prevents your from doing that?

finding how the hell worker application could be launched properly with discord bot enabled in passive mode

as a dumb not really optimal work around...

we can just... make the messaging queue on our own, reinvent the wheel

our website would be sending commands to redis in direct way

and your bot would have background loop that checks the redis

if finds the tasks, takes one, completes and removes when finished

takes the next task and e.t.c.

ideally it could be made without reinventing the wheel with celery

which is made exactly for this

but how to connect celery with discord bot... that's a problem

[lunar geyser]

yes i thougth about something like a queue in a database but that was smt that didn' t seemed "professional" for me and was really janky

[inland oak]

redis is a special NoSQL super duper fast database

it keeps all the data in its RAM memory

and works basically like a key-value dictionary

it is specifically suited to do tasks like that

[lunar geyser]

ok is there any downside of doing that

[inland oak]

well, as far as I heard

the standard library which I like to connect from django to redis... is sync too%

and async libraries for redis a bit unstable

so... again using asyncio.to_thread, or using unstable async libraries to connect

[lunar geyser]

ok ... hmm

ok i will do some research and have lunch but thanks for the good starting point 👍

[inland oak]

u a welcome

[glacial yoke]

is it possible to create a spinning wheel on a website, using django, where people would enter a so called game with different values, therefore having a different chance of winning, then the wheel would spin, and through random using all the chances of all people, it would output the winning person?

[inland oak]

surely. it sounds pretty much possible

[glacial yoke]

Do you know any package that I can use by any chance?

[inland oak]

I think spinning wheel could be drawn with Canvas(HTML+Javascript) if I am not mistaken (not really familiar with frontend)

you can storage your users with Django ORM in postgres for example

https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API/Tutorial

[glacial yoke]

I’m not very good at front end as well, so that’s why I’m asking

This is mostly handled by the browser itself

I don't think there's a way to do it.

But i suggest you look it up

Since I am not sure

i tried tho

cant find anythikg

[versed python]

Yeah

There's no way to do it then

[thick hull]

hmm okay

[turbid mirage]

I have a many-to-many relationship between User and Movie. Movie contains the many with a field name user_liked and a related name users_liked. Based on the active_user, I want to return liked if they added the movie else not liked. In the template, I have an if else that I think should work but it is returning False or not liked for every movie. When I load the page within the context I pass all the movies (movies) and the active_user (active_user). Does my if statement look correct? Is there a better way to do this?

[opal quest]

I wanna use sass in django. Anyone know ytb vid or website can help me out thank you

[gritty cloud]

you could use the sass compiler to compile css into your static files folder

then use {% static %} to get the css

[long jackal]

how do I make the height of this box to the bottom of the page? For some reason if I put width: 100% it will make the box as wide as it can go (which is what I want) but push it's height to way beyond the screen below. All I want is for the width to stay the same and for the height to be as long as the screen minus the title above (not shown in the image but is there if I scroll up).

Code

    <div class="page-content">
        <h1 class="title2">[Game Title]</h1>
        <canvas class="center gameWindow"></canvas>
        <script src=./index.js></script>
    </div>

.gameWindow {
    border: 2px solid black;
    width: 100%;
}

.center {
    text-align: center;
}

.title2 {
    color: white;
    text-align: center;
    margin: 50px 0px;
    font-size: 50px;
}

Hey i'm actually learning Django did someone could explain me what is utility of views.py

I would say it looks correct

All the data is used it seems

Nothing is loaded which is unused I assume

Hello I am learning web development I any one is interested to learn together then contact me!

[kind flicker]

why am i getting an error here? anyone know cos its working fine in a venv but when i deploy it its fucked up compleately

that is the error it is giving me yet i would have 0 clue on how to fix that

[inland oak]

static files are handled differently with debug on and off in django

not sure which you have framework

[kind flicker]

im using flask

[inland oak]

probably same problems

[kind flicker]

see im not using any css files so that could be why?

[inland oak]

are you deploying from windows to linux?

[kind flicker]

nope

[inland oak]

from linux to linux?

[kind flicker]

not that i know of anyway

[inland oak]

from where to where you deploy

[kind flicker]

im deploying on pythonanywhere

from my pc

[inland oak]

what is your OS

[kind flicker]

windows

[inland oak]

lets assume that with 99% chance pythonanywhere has linux servers

[kind flicker]

sure

what would the fix include doing

[inland oak]

you have bg2.JPG named image

[kind flicker]

yes

[inland oak]

if your image in reality has bg2.jpg, it will work in windows

it will not work in linux

[kind flicker]

why?

[inland oak]

because linux has case sensetive file system naming

bg2.jpg and bg2.JPG are completely two different files for linux system

[kind flicker]

so i should try both ways?

[inland oak]

the best way would be for you installing linux (at least in virtual machine)
and just setting up and trying your project there

it will make your debug a hell way easier

[kind flicker]

hmm

[inland oak]

if you deploy to linux, you should better work from linux

it will just make the job easier

[kind flicker]

yeah maybe

[inland oak]

at least it is one of the 12 principles of devops

have your development environment as close as possible to production environment

the rule number something

https://12factor.net/
10th rule

[kind flicker]

ill look into it

im just trying something atm

I fixed it 🙂

i just changed it to lowercase and that worked the job

My Flask website loses scrapped data inserted with python after I reloaded. Does anyone knows how to solve this?

Do you mind sharing the code on how you insert it? Any database should persist data after restart so something is not correct.

[vestal hound]

well

you're not using anything but local memory

[lunar stream]

So that's the reason?

[vestal hound]

yes?

when a process is killed

it returns its memory to the OS

or, more accurately, the OS reclaims it

[lunar stream]

got it. Next step will be setting the connection with the database I guess.

[vestal hound]

you need to persist your data

for a very simple project

you can just use a local file

next level up would be a local database (sqlite)

and for a production setting you probz want a standalone database

I favour Postgres

[lunar stream]

Thank you! I'll make a document and get the data for the website from there.

[vestal hound]

yw!

[vestal hound]

also this is a p small thing but in general snake_case is idiomatic for Python variables and functions

you only use CamelCase for classes

[lunar stream]

gotcha.

[arctic wedge]

Is it possible to use boostrap, Django and a custom CSS file in one project? Im having issues linking the custom css

[clear bone]

yes i think so

[arctic wedge]

lmao I hate it that the moment I ask a question 1 min later I solve it T_T

[lunar stream]

@vestal hound damn, tried with the local txt and it keeps erasing the page

[vestal hound]

explain your problem and what you expect to happen in more detail

maybe I misunderstood you

[lunar stream]

Sorry, This was my issue before My Flask website loses scrapped data inserted with python after I reloaded. Does anyone knows how to solve this?

So, I tried your advice you can just use a local file

[vestal hound]

no

as in

like

from waht I see

you scrape once

every time you run the server

do you not want to do that?

what do you expect to happen?

[lunar stream]

I stopped scrapping each time it loads

got the data into a txt file

from lxml import html
import requests

app = Flask(__name__)

def getDataFromTextLineByLine(textname):
    dataFromText = []
    n = open(textname, "r", encoding='utf-8')
    Lines = n.readlines()
    for line in Lines:
        dataFromText.append(line)
    n.close()
    return dataFromText


gamenames = getDataFromTextLineByLine("gamenames.txt")
gameGenres = getDataFromTextLineByLine("gameGenres.txt")

zip_object = zip(gamenames, gameGenres)

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


def index(user=None):
    return render_template("game.html",user=user, zip_object=zip_object)

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

So, the information will be static.

[vestal hound]

it's scraping

scrapping means "throwing away"

anyways

okay so

[lunar stream]

Anyway, now it's not scrapping

[vestal hound]

it's static

[lunar stream]

yes

[vestal hound]

what's the problem now?

[lunar stream]

But, each time I reload the website it loses all the content I passed through the function def index(user=None): return render_template("game.html",user=user, zip_object=zip_object)

[vestal hound]

ah

okay

[lunar stream]

[vestal hound]

I get what you mean now

nothing to do with your template

zip produces an iterator

your iterator has been exhausted

example

!e

a = [1, 2, 3]
b = ['a', 'b', 'c']

z = zip(a, b)

for x in z:
    print(x)

print('first done')

for x in z:
    print(x)

print('second done')

[lavish prism]

@vestal hound :white_check_mark: Your eval job has completed with return code 0.

001 | (1, 'a')
002 | (2, 'b')
003 | (3, 'c')
004 | first done
005 | second done

[vestal hound]

@lunar stream get it?

zip objects are one use only

[lunar stream]

Ow

[vestal hound]

you need to convert it into, say, a list

[lunar stream]

I'll try that now

[vestal hound]

also, please remember that it's "scraping" with one "p"

🥴

[lunar stream]

Lol

@vestal hound Wow. You nailed it.

I'm one step further now. Thank you!

So yes...zooming away from 100% view in the browser will mess with how lines appear... 😄

[prisma heart]

Should my Django site's main page be an app?

I mean it's just a template so does it require an app?

[sullen pebble]

can i make a website using python??

[wooden ruin]

yes

[sullen pebble]

what are the basics?

[wooden ruin]

there's a frontend(client) and a backend(server). for frontend you should know at least html/css/js and for backend you can use python to create a web server

!resources

[lavish prism]

Resources

The Resources page on our website contains a list of hand-selected learning resources that we regularly recommend to both beginners and experts.

https://pythondiscord.com/pages/resources

[sullen pebble]

hmmm

[versed python]

Technically you don't need an app, but its highly recommended

[burnt zealot]

so this might seem fucking stupid but i'm trying to read a txt file with python and send that string to a javascript file

[versed python]

Just create a core app and use that

[burnt zealot]

So I have my html page running this: <script src="Python/ReadFile.py"></script> to run the python program which is this: Read = open("Assets/MapCol.txt", "r") which opens the txt file in a new tab in chrome for some reason

[raw compass]

Do you have experience with php? We don't do this with python.

[versed python]

What are you trying to do? Browser can not read python

[burnt zealot]

I do not have experiance with php, no

could you guide me to where I can learn how to do this?

[raw compass]

Sorry to assume.

Checkout a python webframework like flask.

You will be able to expose a endpoint that will dump the contents of the file via the web.

[burnt zealot]

I can learn php

[versed python]

You'll find python easier though

[burnt zealot]

probably

[raw compass]

You can try a flask tutorial. And once you get the basics down you should be able to use https://flask.palletsprojects.com/en/2.0.x/api/?highlight=send_file#flask.send_file

[burnt zealot]

How do you execute a python file via html?

[raw compass]

you don't.

You create a endpoint in your web framework of choice and you can expose a python function.

Did you have any luck with the flask tutorial?

[burnt zealot]

web framework?

[raw compass]

Like flask or equivalent.

[burnt zealot]

I don't get why i'm coding up a wbesite in flask, when what i want to do is get a string from a .txt file and pass that to a javascript file

i can't read a .txt with java

[raw compass]

You don't have access to a local filesystem with javascript no.

[burnt zealot]

Yeah, so how would I pass this text to java? Json?

[raw compass]

your browser can prompt the user for a file upload. Is that sufficient?

[burnt zealot]

nah this is an embeded file.

[raw compass]

on your computer or the webserver?

the webserver can serve a txt file.

[burnt zealot]

on my computer, in a folder

I'm trying to get the contents of the txt file as an array

can I put the contents of the txt file in JSON of something and that can send it to java?

[raw compass]

i don't know. What are you using as a webserver?

[burnt zealot]

not really a webserver currently, just running the html file off my computer

[raw compass]

checkout https://stackoverflow.com/questions/14446447/how-to-read-a-local-text-file

[burnt zealot]

nah that gives me an error

[raw compass]

I believe the explanation of this error is in some of the comments of that link. It would have worked though chrome and then firefox disabled it for security some years ago.

Your never going to production with running a html file off your computer like this. Do yourself a favor and install a small webserver and host the txt file like you would in production via http:// or https:// so that this method would work.

hello guys i need help

example user wanna create 500 new entry with orm then user need to wait but if user close the browser the process will cancel right? how i can handle this case ? any suggestion ?

[pearl trench]

thanks man!

[teal tusk]

i dont know if this is the right channel but i need help with webscraping

[jovial cloud]

course_id is a string. If you wanna get the Course object, you have to use its backref(in this case course_payment). To see your object, type the code
for i in query:
print(i course_payment)

[past cipher]

Thanks @jovial cloud - its been a while since I've use alachemy

You're welcome

[ember adder]

In Django, I already have views that inherit from LoginRequiredMixin, which override the dispatch method. I would like to develop a mixin that check if a member has an active subscription, so it would probably also redefine dispatch.

Should the two mixins live side by side in the inheritance parameters of a class or should my subscription mixin inherit from LoginRequiredMixin?

[muted galleon]

Hello, @ember adder

[versed python]

Both would work, but I've personally used the inheritance model

[ember adder]

Thanks for the input.

[tight bison]

Heyy guys, I have a question in mind

So I've been building a python - strapi.js (a kind of headless CMS) integration API for a backend of a website. And I used python requests library to make CRUD requests from the backend to the database system. And this got me wondering, if I could build an entire backend using pure python, what is the advantage of using a framework like Django in this case? Can't I just use python to handle all of the data transactions and stuff like that?

I got the error that told the rest_framework_simplejwt could not be solved although i've install the restframework pip but didnt working at all, anyone can help me pls

[idle marsh]

looking for free host to host my static website (except github)

[wheat solar]

heroku

[dapper tusk]

cloudflare pages, netlify

heroku is overkill for a static site

[wheat solar]

shhhh

but yes lmao

[idle marsh]

what about free domain?

[dapper tusk]

if you are a student, you get a free .tech domain, a free .me domain, and a free domain from name.com for a year each

using the gh student pack

pages will give you a pretty nice subdomain on pages.dev

if you can somehow figure out .tk or .gz domains, those are also free

[idle marsh]

can you give me link ?

[dapper tusk]

http://www.dot.tk/, but idk how to get it to give an actual domain

[covert kernel]

freenom

[versed python]

Can you explain how to avail this?

I already have github student pro account but dont see any option to get a domain

[dapper tusk]

https://education.github.com/pack/offers?sort=popularity&tag=Domains you should be to figure it out from here

I never actually did this, since I got .xyz for a dollar for a year

so until that expires, I will save those offers

[covert kernel]

Now type florida-dm.ga in the availability bar

And then checkout

[covert kernel]

Done, now check your mail

[native tide]

am i able to build a complex website with many functions with just python, html and css?

[dapper tusk]

yes, though javascript will let you have a more pleasant UX

[exotic pike]

define complex....

[native tide]

let's say for example i wanted to build an ecommerce site

[eternal blade]

If you want to make a website with very complex functions you will probably need to use a frontend js framework, like react.js

[exotic pike]

Agree on this..

[native tide]

alright, so i should learn javascript first to a semi-pro/pro extent as well as html and css

[exotic pike]

if you want a dynamic UI/UX you should use javascript

my current stack is django & react.js

[eternal blade]

I guess intermediate js should be enough

[native tide]

alright, thank you for the help

[eternal blade]

But you need to know OOP

[native tide]

sweet

i already know it in python and they say that once you learn 1 programming language the others become easier to learn

[exotic pike]

yeah,

[dapper tusk]

you don't need a JS framework

it just makes for a better website than pure backend templates

[exotic pike]

can also go with jquery for dynamic UI...

[eternal blade]

Yeah, when I started learning js I already knew python, stuff were a lot more easier to understand

[dapper tusk]

you don't even need dynamic UI

[eternal blade]

It's the the difference in syntax, most of the concepts are the same

[native tide]

we're on the same boat my man, i've done python for the past 3 years and got bored. so decided to learn new language. plus it'll be better in the long run for job opportunities

[eternal blade]

app = flask.Flask(__name__)

@app.route('/')
def default():
    return "online"

if __name__ == '__main__':
    app.run(host="0.0.0.0")
``` for some reason this works on localhost but not on my local ip 192.168.xx.xxx

[thorn igloo]

how are you running this app?

[mystic wyvern]

Is django equal to or greater than node.js?

[thorn igloo]

nodejs is like python

i mean python is what you would compare it to

[mystic wyvern]

nodejs language ?

[thorn igloo]

what?

what i mean is nodejs is more comparable to python rather than django

django is a web framework that runs on python,

[wooden ruin]

node is a runtime @mystic wyvern that allows u to use javascript outside of a browser

hence allowing you to use it in things like servers

nodejs has backend frameworks such as express or nest which are comparable to django

[ashen crescent]

I had two instances

I fixed it

[idle marsh]

Hello guys i'm facing this issue

[nova sonnet]

is there a way to pass a count of a queryset into the template without modifying the original queryset?

for example I want to pass a count of each object where either one of the attributes are either true or false

[covert kernel]

Dunno, try registering one again, this had worked for me

[nova pewter]

# Create your models here.


class User(models.Model):
    first_name = models.CharField(max_length=128)

from appTwo.models import User

    class Meta:
        model = User
        fields = '__all__'

from appTwo.forms import NewUserForm
from django.contrib import messages

# Create your views here.


def index(request):
    return render(request, 'apptwo/index.html')


def users(request):
    form = NewUserForm()

    if request.method == "POST":

    else:
        print(form.errors)
        print("invalid")

    return render(request, "appTwo/users.html", {"form": form})

why is my form returning "invalid"?

show me the html code

[ionic raft]

I'm learning my way through Django for the back-end of the web application I'm building. React is my planned next step for the diagramming part of the 7th app within this web application. I hear really good things about React.

[ionic raft]

I've used form = UserSignupForm() for my sign up.

From my forms.py file for the app...```py
class UserSignupForm(UserCreationForm):
"""UserSignupForm for the user to create an account."""
email = forms.EmailField()

class Meta:
    model = User
    fields = ['username', 'email', 'password1', 'password2']```

If there is something I'm wondering about it is the use of all for fields. I get why, but why not be specific?

[nova pewter]

<html>
  <head>
    <meta charset="utf-8" />
    <title>Users</title>

      {{form.as_p}} {%csrf_token%} <input type = "submit" type="button"
      value="hit it"
    </form>
  </body>
</html>

[ionic raft]

Out of habit I'll throw the csrf ahead of the form itself. Doubt that's an issue though.
You are missing a closing >```html
<!DOCTYPE html>

<title>Users</title>

<h1>Here are your users:</h1>

<form method="POST">

  <input type = "submit" type="button" value="hit it">

[nova pewter]

yeah i just checked the closing >, also i'll keep that in mind

[ionic raft]

Give it a go with the fixed >

[nova pewter]

fixed

[ionic raft]

Side note, I'm not a fan of fields = '__ all __ ' for a couple of reasons. One of them is security. And the other is clarity

[nova pewter]

thanks for the help

[ionic raft]

Fabulous

[nova pewter]

noted

[ionic raft]

Good luck.

[nova pewter]

thanks, i'll try not to make these trivial mistakes and posting here, hopefully XD

[ionic raft]

It's all good. I make PLENTY of mistakes...and I learn through them.

bruhh

[ionic raft]

BRUH

[dusk portal]

did u fixed that?

[nova pewter]

yep

[ionic raft]

Yah. He';s good

[dusk portal]

nice

what was the prob

[nova pewter]

just a missing ">"

[dusk portal]

ohh lol

[nova pewter]

thanks for replying

[dusk portal]

i too saw

[ionic raft]

Plus a couple of tips around setting up fields and forms

Oh, and exclude = [] for fields to explicitly hide are also good for security

[nova pewter]

well i saw it right after posting it, but didn't thought that it will fix the issue

[dusk portal]

btw while working with a form i saw u wrote {{form.as_p}} then csrf tokens , remember after u write method=POST

[ionic raft]

I never cease to be amazed how the most trivial of crap causes bugs

[dusk portal]

after that line u have to write csrf tokens

not after form

;-;

[nova pewter]

cool

[ionic raft]

App 2/7 done for LanesFlow...processes...

[dusk portal]

nice\

are u good at rest framework @ionic raft

[ionic raft]

Not done much with it. I've been building queries (CRUD functionality) in views as I've needed and met all my needs. But then I've got a complex DB I've also build up too. About 20+ tables/models. AKA I've managed to get all the CRUD I need through Django alone and not needed to strike out into REST yet

[exotic pike]

Define the best..

[ionic raft]

So, turns out there's a record of the past 3.5 months of learning Python/Django and building this web app. This brought a smile to my mental head.

[dusk portal]

oh have u worked with drf token authentication

[ionic raft]

Nope.

I've built the entire DB in my web app. The only thing I'm connecting out for is to Stripe for subscription payments.

[dusk portal]

oh

what r u doing now rn @ionic raft

[ionic raft]

Just fixed a nasty bug where if I changed the name of a team or organization templates broke. I realized I needed to query by id and fk_id fields rather than names. Glad I caught that now ahead of alpha testing...that would have been nasty out in the field

Just about finished app 2/7 though. Onto app 3 tomorrow. Clean up, testing, tweaking...

[dusk portal]

umm if u ask me i have been learning flask from april as it was my 1st framework and was new so learned it till June ig then from 7th of june i just started working on django

then then from 3rd of August Django Rest Framework

[ionic raft]

I spent June learning Flask. I really enjoyed it. My first framework too. Been on Django since July...love it.
How are you finding Django?

It's the little things...like alternating styles for looped grids per this...

[dusk portal]

hh

[ionic raft]

I'm really liking this design language and layout for this app. Hoping testing validates the UX

[dusk portal]

as i was new to docs world so completed https://docs.djangoproject.com/en/3.2/intro/ this docs 10 days then i was gone mad and decided to become good at django , so corey schafer's video , just django playlist , codingforenterpreneur then Dennis Ivy vids

[ionic raft]

I got started w Corey and Django. Did first 12 parts of his Django series. Going back to 13 for when I promote to production on Linode...and www.lanesflow.io will be ALIVE!

[dusk portal]

made todo app + todo app with authentication + contact page app + auth system in django then forms in django class based views then 1 ecommerce type of app , then 1 corey's blog app

my frontend is like wtf bro

it's too bad too too bad

[ionic raft]

Yah...I called the blog "Articles" and did a task list too...

[dusk portal]

have u discovered django channels

[dusk portal]

oh

u learned about that search functionality backend cez it's imp

@ionic raft

[ionic raft]

Not following..."cez its imp"?

[dusk portal]

because it's important i mean

btw how u learned payment gateway wow i wanted to learn it too

[ionic raft]

Well, still thinking on that...Search isn't as key for my apps...Because there's a hierarchical structure to finding things. However, I think I will circle back to search across the DB at some point.

My priority is a UI design that makes it so you don't really have to search

[dusk portal]

can we have a good deal

very good

[ionic raft]

Oh yes...Stripe...

[dusk portal]

i have some problems related to reset password and payment gateway and some integration

u teach me things that u know

i'll teach u things

that u dont know

it's ez cez searching advanced topic on internet and getting answer is like

1% chances

[ionic raft]

Reset password...likely easier than stripe...stripe was a bit nasty...not much out there...had to piece it together

[dusk portal]

yes

vc?

nice

[ionic raft]

Can even send the email over...

[dusk portal]

u coding from how many years

[ionic raft]

from their account...I started with Python Apr 16, 2021...Django in July...here's my git commits...

Here's the Stripe gateway with logo...

[dusk portal]

i dont push that much to git

[ionic raft]

I'm actually REALLY good with the user going clearly over to Stripe gateway. I want subscribers to know that Stripe, the experts at managing billing, manage billing and their credit card info. No saving credit cards for me. Outsource ALL that to Stripe

I push to git with every major update...will track until I get something working and tested. Then I push.

[dusk portal]

ohh

[ionic raft]

I took 1 week off after having learned for over 2 months...then back to it

[dusk portal]

i make whole proj

then push

[ionic raft]

Wow....I couldn't do that. I want a record of the major commits...so i can track back if I need.

[dusk portal]

i iz noob in git

lmao

[ionic raft]

I'm noob too...but after I lost a few days of work through some weird stuff I was determined to learn git. So I studied it

[dusk portal]

nice

[ionic raft]

So password reset...

[dusk portal]

ik how to do that

but error

[ionic raft]

What's the error

[dusk portal]

wait

lemme open that proj

yo @ionic raft

[ionic raft]

I followed Corey's password reset method. So not sure I'll be of much help.

[dusk portal]

app_name='users'

urlpatterns = [
    path('',v_views.register,name='register'),
    path('profile/',v_views.profile,name='profile'),
    path('login/',views.LoginView.as_view(template_name='users/login.html'),name='login'),

    path('password-reset-complete/',  views.PasswordResetCompleteView.as_view(template_name='users/password_reset_complete.html'), name='password_reset_complete'),
]```

[dusk portal]

ik ik and yes that's the one best method

[ionic raft]

I like the token approach. One gap for me is if they entered a broken email and lose their password they're locked out. But that can be fixed with a Contact ticket and admin\

[dusk portal]

;-;

[ionic raft]

I'd check your template...it looks like a broken url build to me

I'm looking at your url pattern syntax...

[dusk portal]

ohk

{% extends "app1/base.html" %}
{% load crispy_forms_tags %}
{% block content %}
    <div class="content-section">
        <form method="POST">
            {% csrf_token %}
            <fieldset class="form-group">
                <legend class="border-bottom mb-4">Reset Password</legend>
                {{ form|crispy }}
            </fieldset>
            <div class="form-group">
                <button class="btn btn-outline-info" type="submit">Request Password Reset</button>
            </div>
        </form>
    </div>
{% endblock content %}```

this is the password reset (1st step html code)

[ionic raft]

Might have spotted something...

[dusk portal]

oh where

[ionic raft]

Here's what I have py path('password-reset/', auth_views.PasswordResetView.as_view( template_name='users/password_reset.html' ), name='password_reset'),

Check auth_views.PasswordResetView...

Yours is

    path('password-reset/', views.PasswordResetView.as_view(template_name='users/password_reset.html'), name='password_reset'),```

[dusk portal]

where in name url or view

[ionic raft]

It's a built in lib...you need auth_views I think

[dusk portal]

ohh

[ionic raft]

in url pattern

Here's my url.py

urlpatterns = [
urlpatterns = [
    path('signup/', signup, name='signup'),
    path('profile/', profile, name='profile'),
    path('signin/', auth_views.LoginView.as_view(template_name='users/signin.html'), name='signin'),
    path('signout/', auth_views.LogoutView.as_view(template_name='users/signout.html'), name='signout'),
    path('password-reset/',
         auth_views.PasswordResetView.as_view(
             template_name='users/password_reset.html'
         ),
         name='password_reset'),
    path('password-reset/done/',
         auth_views.PasswordResetDoneView.as_view(
             template_name='users/password_reset_done.html'
         ),
         name='password_reset_done'),
    path('password-reset-confirm/<uidb64>/<token>/',
         auth_views.PasswordResetConfirmView.as_view(
             template_name='users/password_reset_confirm.html'
         ),
         name='password_reset_confirm'),
    path('password-reset-complete/',
         auth_views.PasswordResetCompleteView.as_view(
             template_name='users/password_reset_complete.html'
         ),
         name='password_reset_complete'),```

[dusk portal]

ohh

[ionic raft]

And my pword rest has been working great

Oh wait...also have

from django.contrib.auth import views as auth_views```

[dusk portal]

hmmm

[ionic raft]

I named as auth_views to clarify naming for views

I'd check your html templates though. That kind of error I see when the static url is not built correctly

[dusk portal]

hmm

[ionic raft]

I've got to get to bed....12.50 am here. Good luck though. Ping me tomorrow if you can't find it

[dusk portal]

same error uuf

ohk

[ionic raft]

But if it were me, I'd check every {% url 'name-here' %} in my html file

[dusk portal]

gn

[ionic raft]

That error message is basically saying, hey, I can't find that url you're clicking on...

[dusk portal]

yes

[ionic raft]

So it's in a template somewhere...Check the page with the link you clicked...it'll be there I bet

Good news, find + '{% url ' will get you all the references and you check each one

I'd also go with from django.contrib.auth import views as auth_views and use auth_views as the reference in your url_patterns

[dusk portal]

ill see ur code and follow along

ur repo link

[ionic raft]

My code is close to yours...

here's your code refined...

urlpatterns = [
    path('',v_views.register, name='register'),
    path('profile/', v_views.profile, name='profile'),
    path('login/', auth_views.LoginView.as_view(template_name='users/login.html'), name='login'),
    path('password-reset/', auth_views.PasswordResetView.as_view(template_name='users/password_reset.html'), name='password_reset'),
    path('password-reset/done/', auth_views.PasswordResetDoneView.as_view(template_name='users/password_reset_done.html'), name='password_reset_done'),
    path('logout/', auth_views.LogoutView.as_view(template_name='users/logout.html'), name='logout'),
    path('password-reset-confirm/<uidb64>/<token>/', auth_views.PasswordResetConfirmView.as_view(template_name='users/password_reset_confirm.html'), name='password_reset_confirm'),
    path('password-reset-complete/', auth_views.PasswordResetCompleteView.as_view(template_name='users/password_reset_complete.html'), name='password_reset_complete'),
]

My repo is private. The idea is far too valuable to open up

[ionic raft]

I inserted spaces after commas...and renamed views to auth_views

[dusk portal]

hmm

[ionic raft]

But the syntax for your url_patterns is sound. It's in the html template somewhere...almost certain

hey guys, i am really new to programming and am trying to make a web app, i am building the application front end in svelte and backend in fast api. i have noticed that svelte needs nodejs to run and fast api requires uvicorn, so my question is that, while deploying my app will my app require both node.js and uvicorn for frontend and backend seperately, in which case wouldn't i be better of using nodejs for backend too in order to reduce the load on backend since i can avoid running uvicorn completely and run backend and frontend both on node.js itself? sorry if this is a noob question, since i am new to the scene i havent got much idea about anything, any help is appreciated.

sure, they'll use a lil more resources, but not to the point where it matters, most big web apps run hundreds of different servers and services, overall it's not gonna affect you much / to a noticeable amount by running the two together as opposed to one large system.
