[clear bone]

thats all i have haha

[valid void]

is django.contrib.staticfiles installed in your settings.py -> INSTALLED_APPS ?

[velvet yew]

Path looks correct so yeah check for the django.contrib.staticfiles

[clear bone]

yep it is

[velvet yew]

Hm

Can you show your full folder structure for the image?

[clear bone]

and this is in the base directory

[valid void]

I think you have to add a STATIC_ROOT that contains the path to your Static folder

[velvet yew]

The full django project path please

[clear bone]

yeah i added that but still no luck unfortunately

[valid void]

Have you executed the collectstatics function from manage.py ?

[velvet yew]

Is the static in the app's folder?

[clear bone]

no it isnt

[velvet yew]

Move it

[clear bone]

no i have not, isnt that used during deployment?

[broken mulch]

how do I get the IP address of a request that I can request back some data?

[valid void]

Yes it is

[clear bone]

done, still not working

[valid void]

But it's working fine with Debug=True

For me

[broken mulch]

can someone answer

like I can do requests.get(the_ip)

maybe in headers?

[valid void]

@broken mulch https://stackoverflow.com/questions/4581789/how-do-i-get-user-ip-address-in-django

[velvet yew]

Is the full path djangoproject/app/static/app/image.jpg?

[clear bone]

right this is why im so confused

[clear bone]

yes

wait no it is not

[velvet yew]

I just recreated the same and worked fine for me

[broken mulch]

let's see if it works

[clear bone]

@velvet yew my project and app are on the same "level" in the directory

[valid void]

😮

[dapper tusk]

django.contrib.staticfiles will not serve static files when not in debug mode

[valid void]

Project and app are on the same directory ?

[clear bone]

yes

[velvet yew]

That's how it should be

[valid void]

Not really, you should have project/project (setting.py etc.) and project/app1, project/app2 etc.

[velvet yew]

I'm rather confused at your directories let me double check

[valid void]

project/manage.py

[broken mulch]

it's not working

[velvet yew]

Yeah that's what I meant

Just not sure it's what he meant

[winter adder]

Anyone?

[broken mulch]

when I visit that IP it's loadin forever

[velvet yew]

Copy the full path to the image

[valid void]

wdym ? @broken mulch

Show code

[clear bone]

C:\Users\Me\Desktop\alb2_rec\albumApp\static\albumApp

[broken mulch]

so on that IP I am hosting a web server

and I'm visiting another web server with that IP

when I type the IP i received in the browser (and with a correct PORT)

it takes too long to respond

I'm currently using an ubuntu VPS to dev my Django Application. There is no Apache installed, no Gunicorn or nothing. Just using the manage.py runserver ipserver. What is the best way for me to add a domain name to my django app ? Do I need a webserver (like apache or Gunicorn) ? Thanks !

[opaque rivet]

good resource: https://books.agiliq.com/projects/django-orm-cookbook/en/latest/index.html

[gritty cloud]

domain names aren't made, they are typically bought

you should type your domain name into your browser to test if it exists

then buy it from the person selling it

note that this takes real money

you can also go to sites like godaddy.com do get a domain

https://www.godaddy.com/domains/domain-name-search

[late creek]

or you can just use a free domain on launch to save money

[valid void]

I used DigitalOcean to create a django Droplet and a Postgresql database

[late creek]

and also yeah, you need to use nginx and gunicorn then bind an A record to your vps' IP and then accept traffic from that domain from nginx or apache wtv ur using, but I recommend nginx

Flask gives the warning to not use it's built-in server in production. If my (open-source) package spins up a server local to the user, is that considered production ? In other words, do I need to include tornado , aiohttp or something similar?

is there a way to pass the same variables through every render_template?

i have multiple pages that all rely on a variable that represents the current user session, and i have to pass it through every time

Hello

How to make a file download?

Im making print(filebytes)

But nothing happens

https://stackoverflow.com/questions/18339745/how-to-deploy-zip-files-or-other-binaries-trough-cgi-in-python

This is not working

[native tide]

can you post your code?

!paste

[lavish prism]

Pasting large amounts of code

If your code is too long to fit in a codeblock in discord, you can paste your code here:
https://paste.pydis.com/

After pasting your code, save it by clicking the floppy disk icon in the top right, or by typing ctrl + S. After doing that, the URL should change. Copy the URL and post it here so others can see it.

[wispy ice]

Check the link, is almost the same as the stack overflow one

I use python CGI

And sys.stdout(file)

Not print

But it does not trigger the download file

Im using lighttpd

Ubuntu

And python 3

[native tide]

elaborate?

it would be useful if you still could give us the code snippet

[wispy ice]

There is not much many code. I just add headers, and then stdout the file readed

And nothing happens

I expected a file downloading

Maybe it's impossible

I call the cgi-bin from a ajax/jquery post

And i want in response the file

[native tide]

do you see data from other prints

in response

to your request via cgi-bin

[wispy ice]

Yes

If i print text, the text is displayed in consile

F12 console

If i catch the response

So the program works, but not as intended

[native tide]

what do you see in response

can you post it and redact all sensetive data

[wispy ice]

In 12h ill return and post it to you @native tide

Ty for helping

Now ill go and sleep, my brain hurts

[native tide]

taking breaks is very important otherwise you might burn out and completely give up

i might be off to sleep soon so dm me

if anything

Question. Anyone familiar with Django and class based views? I'm trying to use an UpdateView form to save to the DB. It works on a follow up Save, but not the first. I am only saving to the same object.

Flask gives the warning to not use it's built-in server in production. If my (open-source) package spins up a server local to the user, is that considered production ? In other words, do I need to include tornado , aiohttp or something similar?

[real fossil]

Production in computer science means released to the public for some reason. Running a local server is fine just don't use it for an internet facing service.

[subtle sun]

Thanks. So for just providing a web user interface to an application running locally, Flask’s built-in server should be fine, right?

[real fossil]

I believe so, as long as it's not public facing and just local

Hi guys

[subtle sun]

Thank you.

[ionic raft]

So...I've just finished the first major part of LanesFlow. This screenshot is of the dashboard for projects (PIPs - or Process Improvement Projects).
And I've pretty much completed the Project Management part of the app, along with the initial part of the dashboard. There is a fair bit of automation behind the scenes. Project rating for evaluating if a project should be taken on (and where projects can be compared to each other is now working). This screenshot shows three stages of the journey being described by the dashboard.
Project Selection Summary...shows projects with automated ratings based on 5 drop down field selections.
PIP Progress...shows the PIP in progress, what phase they're in. In this one, a target date for the end of the phase is missing, so the heading "Target Date" is highlighted red.
Completed PIPs...shows those PIPs that have been completed.
All in all this is very exciting and is looking and working better than I could have hoped. Lots of functionality behind the scenes to make this happen.

Feedback on initial impressions of the presentation layer welcomed. Being in a sole-developer bubble is tough. Looking forward to alpha testing.

[kind sluice]

Yes?

Hey guys im developing an small api with Django for a test, but a got some issues with the data modeling. Can anybody helpeme?

Basically, the relations are ok, but when i make the queries on the service, the response that i got its not the users name(for a example), but its the Id.

here an img of my service:

and this one is my models:

and thats is the response of the check in and chack out endpopints

check_in

check_out:

can anybody help-me?

[thorn igloo]

where are you even modeling a username here?

if the username is in another table and you're using the user id as a foreignkey, you need to use joins to combine the data

[honest tartan]

hold

here

usuario = is the username

and Check In usuario takes the nome of Usuario Table

[versed lotus]

usuario seems to be a foreign key. A one-to-one-field is likely just the refence to the other table. meaning it only contains the id of the user, and you need to resolve the correct record from the user table (no idea how exactly that works in django)

[thorn igloo]

one way to get the username would be to do a join when querying the data, i'd suggest looking at how to achieve that in django. i'm not familiar with it

[versed lotus]

though it's probably specific to the rest framework you're using

[honest tartan]

the i know but im already clalling the ORM method to make the join and the join are working, the problem is that is coming the id of the field and not the name

[versed lotus]

it's probably an issue with your serializer then? not sure

[thorn igloo]

if that's the case, are you sure you specifying the right column?

cause if the id is appearing, it probably means that's what you are referencing

[honest tartan]

well i only follow the documentation:

here a example: class CheckoutViews(viewsets.ModelViewSet):
queryset=CheckOut.objects.select_related('quarto').all()
serializer_class=CheckoutSerializado

quarto its the column of the related table

[honest tartan]

followed

[thorn igloo]

can you link docs?

[honest tartan]

sure, hold a sec

https://docs.djangoproject.com/en/3.2/topics/db/queries/
https://docs.djangoproject.com/en/3.2/ref/models/querysets/

[thorn igloo]

can you link the specific one you used?

like the query

in the docs

too many

[honest tartan]

the last one, um look for select_related

you*

[thorn igloo]

ok, in your checkinviews functions, does query set return a list?

i mean is queryset a list etc

if it is,

if you do something like this

for item in queryset:
  item.usuario # this is your userobject, 

item.usuario will represent an object for the user table or class in this case,

so you can just reference the username like item.usuario.username etc to get the username

if i understand what select_related does correctly

[honest tartan]

hmmm let see here if this works

[vestal hound]

select_related is purely an efficiency thing

it doesn't change the output of your query

[thorn igloo]

??

[vestal hound]

what?

[thorn igloo]

i don't understand what your statement is in relation to

i was just telling the guy how to get the related data he wants, as suggested in the docs

[vestal hound]

I'm clarifying that select_related is not needed to perform a join in Django

[thorn igloo]

i see

[vestal hound]

it serves only to avoid the N+1 problem

[thorn igloo]

how would you actually perform a join in django though?

[vestal hound]

in other words, if you're not getting the related objects that you were originally looking for, select_related wouldn't help

okay so this is something I found a bit hard to wrap my head around at first?

but

say you have two models: Country and Person, with the latter having a FK to the former

okay, backtrack a bit

the concept of "join" doesn't exist in the same way in Django

so it depends on what you want to get out of it

say the country has a gdp column and you want it to be present in each instance of Person

then you would do Person.objects.all().annotate(country_gdp=F('country__gdp'))

which I believe is similar to what the original question wanted

(two underscores mean "go through this table" in Django)

[thorn igloo]

it's a simple case of linking related data in this case .. i.e primary key exits as a foreignkey on the other

[vestal hound]

isn't that the case here too?

like clearly if you want to perform a join, you must want some column from the related table

[thorn igloo]

how are you relating the foreign key here? and checking if it's actually in the two tables?

[vestal hound]

it's not done explicitly

but

I mean

so on each instance of Person

there will be a country_gdp attribute

and that represents the value of the related Country's gdp attribute

i.e.

equivalent to

SELECT person.id, country.gdp FROM person LEFT JOIN country ON person.country_id = country.id

or something like that, I don't often write raw SQL

[thorn igloo]

ok, and an inner join?

[vestal hound]

in this case they would be the same

[thorn igloo]

what? left join and inner join will never return the same thing

left join shows everything on the left side and only filters the right

while inner join filters both

so, if you're saying what you showed me is a left join, surely there has to be some sort of different syntax for an inner join

[vestal hound]

that is literally untrue…

where every row in the left table has a match in the right table, they will return the same thing.

and that must be the case here because of the FK constraint

i.e. every Person has a Country

[vestal hound]

that’s what I’m saying

there is no way to perform an arbitrary join, AFAIK

you would need raw SQL for that

[thorn igloo]

you said that performs a left join, i asked you about an inner join and said it would be the same thing?

[vestal hound]

it would produce the same result

which I think is a reasonable interpretation of “same thing”

[vestal hound]

note that that was in the context of this

[thorn igloo]

you're saying an inner join and a left join would produce the same thing?

[vestal hound]

yes?

[thorn igloo]

bruh

[vestal hound]

because of this

[thorn igloo]

i guess that would make sense in that case

[honest tartan]

ill try this

thanks for the help

Hello everyone, I created a Django Doplet in DigitalOcean, and I tried to create a domain name using 1&1. So I created my domain, I used a subdomain that I linked to DigitalOcean DNS. It worked well, but I don't want the site to be accessible anymore, so I deleted all existing links between DigitalOcean and 1&1, but the site is still available. Do you know why ?

I used this : https://www.digitalocean.com/community/tutorials/how-to-point-to-digitalocean-nameservers-from-common-domain-registrars#registrar-1-amp-1

And I deleted everything after

But the site is still available...

Is it linked to the TTL value ?

Hey guys, anyone familiar with Cloudinary for django, i have a question

[dense slate]

You can chain filters on the query for "AND" and you can use the Q operator for "OR"

[versed python]

Maybe you're still viewing the cached version?

[dense slate]

Yes, you do that in settings.py

You just supply the db name, port (of postgres, 5432 by default), ip (of the linux server), username, and pw in your settings.

[valid void]

I'll try to delete cache

[honest tartan]

@vestal houndman didnt work

still on the same

Does postman provides good documentation for API. If yes why when doing some research, I found always that swagger and openAPI and few other are always more recommended.
It is a documentation that must be prepared for a front-end developer to ingrate the services in front.

I want to edit the LoginRequiredMixin , so I want to create a custom class but im not sure where to safe it

I've got a Django project I'm working on as my web development training, and while I'm decent in Python + backend/devops stuff, I'm struggling with the JS parts. I'm looking for someone who would like to contribute with some JS knowledge and learn/practice JS (and Django) together on the project. Shoot me a DM if you'd like to collab

[dense slate]

What's your project, out of curiosity?

[velvet yew]

It's a SEO/marketing toolkit, I'm automating a lot of stuff I'm doing on a daily basis for me and my SEO peeps, and I'm creating a dashboard for it, but doing it with Django only without any JS has quite a few limitations hence why I'm looking for someone who's familiar with JS

How do i use html to request a file and python code to download it

Hello there people of the internet, is it better to use react together with django, or just use normal html, css and javascript through the django templates?

[wispy ice]

For other related thing

[dense slate]

Having a decoupled front-end like React or something is the more thorough and professional way to do it but you don't have to. You can just use Django templates and get by just fine.

Depends what you need, as always.

[limpid python]

.info {
    width: 80%;
    margin: auto;
    text-align: center;
    padding-top: 100px;
    background: #3e4c61;
}

how to I set the background color to the full section, without changing the width

[dense slate]

Like this?
https://www.w3schools.com/howto/howto_html_download_link.asp

[glacial yoke]

but the functionality is pretty much same, isn't it? React is just more organised, right?

[dense slate]

Not exactly. React does a lot of extra stuff, like allow for managing of state of objects/data, and refreshing aspects of the DOM as needed rather than the entire page.

[glacial yoke]

display: block;

[wispy ice]

Not really @dense slate, i need to click the button, the file is generated in the server, and then its downloaded

Its not something static

[limpid python]

ok, thanks

[dense slate]

Ok so the content of the file can be dynamic?

[wispy ice]

Yes, but size will be always the same

[limpid python]

.info {
    width: 80%;
    margin: auto;
    text-align: center;
    padding-top: 100px;
    background: #3e4c61;
    display: block;
}
```?

[dense slate]

Yea I mean you would ajax a request to the backend, handle that on the server and return the data. then just download however you would normally do that on the front end.

I don't have any actual examples.

[glacial yoke]

so if I want to make something complicated, that would always need constant data management, and active use of the plugins and stuff, it's better to use react?

[glacial yoke]

yeah, that hsould work

[limpid python]

nope

[dense slate]

I would, yea.

[wispy ice]

The "then just download" is not working :(

[limpid python]

i have the margin set to 80, but i cant change, but i want the background to cover it all

[glacial yoke]

put the background colour into the body section of your css

[dense slate]

I don't have a lot of experience with that, sorry. I'm actually going to be doing that this week - create a PDF from html and allow the user to download that. I just haven't done it yet (and am using a library)

[limpid python]

ok

[wispy ice]

Ty, appreciated

[glacial yoke]

so then it ignores the 80% width

[limpid python]

oh yea

ay, thanks!

[glacial yoke]

or use a separate class, like "container", and set the width to whatever you want there, so that it's more neater, and you can use it on several objects in your website, if the design is the same

[limpid python]

oh yea, i may change that later on depending on how I want the site to look

anyone there who can help me with this error

this error is throw on an async msg when i try to find by id in a mongoose database

[quasi field]

Is this just a bug in Pyharm, or am I doing something wrong with the HTML? page displays fine, just that Pycharm is bugging me with this warning

(Django template)

[dense slate]

What's the actual warning?

[quasi field]

Oh sorry, it's just saying that the "closing tag matches nothing" although it should be closing the <dt>

I'm guessing that Pychamr Community can't parse the Django for loop and is thinking that the HTML is invalid, but that's just my suspicion

the <dl> tag is closed btw, just not in the image

[ionic raft]

On a related but divergent note...I have some complex template conditioning that appears to result in errors in PyCharm around tags. PyCharm is suggesting to remove a tag, but methinks there's a bug in their parser that means PC doesn't always nail errors. My experience is that I occasionally get false-positives...I'm getting a red-underline and "remove tag" suggestion and yet the web page renders perfectly...According to PyCharm this screenshot shows a web page that should be broken, and yet to my eye is rendering exactly as intended.

[quasi field]

Yep sounds like what I'm experiencing, the page loads fine (not as pretty as that one) but Pycharm doesn't like the HTML

[proven elk]

hi everyone

do u know how to use clound mongo database with django frame

[ionic raft]

This is the end of the html file...
In all fairness to PyCharm, sometimes the conditioning and looping for a template can be really quite intense. There's a lot of things going on in the application layer to make that page possible. And I'm only using the presentation layer to filter/condition or loop. However, the net result is still some intense template layout.

Sorry but I had to post this if anyone can anwer this, https://www.reddit.com/r/Python/comments/p2ndv0/python_webassembly/

[quick cargo]

Tldr yes, look at oxide, no its not for frontend

Python as a language is arguably the hardest language to try embed into wasm

Outside of shipping an entire interpreter with the wasm code

If you want to do frontend systems you're far better of just using normal js

And js frontend frameworks

Wasm in general is still very new and had many limitations which vary across browsers

Will wasm ever become viable as a frontend framework for production? Maybe, yew.rs with rust is probably the most promising, but that still requires interfacing with js and wasm binaries are still just massive blobs leading to slow timez

Will python ever become a frontend browser framework language with wasm? Almost definitely no

[native tide]

Would be nice tho, I like python a lot and I want it to be my primary and only programming language.

Trying to make an API with fastapi
How do I go about managing tokens? like generating/regenerating them and saving keys/secrets?

[quick cargo]

Often 1 lanuage is never enough, another lanuage may be better in situations than others.

E.g. Java and kotlin for android apps

Lua for embedded scripting

Swift for IOS apps

Js for frontend web work

Good day everyone, I am wondering how you all approach integrating your front-end with your back-end source without putting everything in the same project. For instance, looking to use React on a small portion of my site. How can I keep my React code in another project, but have easy access to development?

some kind of script that copies over the compiled javascript? But then you have to build each time?

[ionic raft]

A good question. I'm deep into a Django web application project with about 8 apps. I'll be using React for just 1 of those apps. All back-end development so far. I'll be curious to see what answers come forward...

[rare oar]

Yeah I did it once before where I was lazy and just dumped it all into a package on my back-end. It just felt wrong and out of place

[ionic raft]

As for the direct answer, I've been making extensive use of the application layer to query the DB, and to set up the front end through context dictionaries.

It's working really, really well so far. But it's all text/file data. The final app for phase 1 will be an diagramming and that's a whole different bag

[ionic raft]

What is helping me is to develop all the apps that won't need JS in the back-end first. Get that down, and then focus on the final app from the front-end in.

I'm actually blown away by how fast you can build in Django when you get the hang of it. Just built a full on complex app in under a day.

[rare oar]

hmm, I suppose I could make the api first. Front-end is just a quick admin dashboard to change some settings. So it'll have access to a very limited private api

[rare oar]

Very nice. First project I did was Django. Probably did every bad practice in the book

This one I'm trying out FastAPI. So far liking it

[ionic raft]

Well I read two scoops of Django to get some best practices down. But I KNOW there's refactoring to be done. However, I plan on building a paid dev team for that once this goes to pitch

[rare oar]

This channel so dead 😦 It's just you and me haha

[ionic raft]

I'm doing all my querying through views.py files. Likely not best practice for other devs working on this. But right now I'm the sole dev...

and it's working

[rare oar]

tbh ActiveRecord patterns really promote you doing it in views.py so I don't think you are doing anything wrong

[ionic raft]

The thing is, once I worked out how to query and update the DB on form saves, you know, save the field they filled in the form, and did coding to update fields not showing...all I needed

[ionic raft]

phew
Only started using Dj this July...so ultra NOOB here

But the speed of dev in Dj is astonishingly fast

[rare oar]

site looks good. Congrats. DId better than me on my first try

by second try is a monolithic abomination

[ionic raft]

This is a monolith. But it's fitting. it's a web app for business to improve quality and their profits. Built on 20+ years of consulting experience and tools I train. It's automating me as a business consultant.
The tagline. Complex Made Clear.
The vision. A business consultant in your pocket.
The entry-point. A free subscription to try it out.

[rare oar]

Are you pitching me? 😄

[ionic raft]

Nah. Always curious to see reactions.
Besides, the entry point is free. There's nothing to pitch.

It's a business to business tool tho. Nothing like it out there that I'm aware of. The final app will be a diagramming one for something i call Collaboration Mapping. That's the BIG one. When I nail that...
In the meantime, I don't know a scrap of JS. I'll be learning that next.
But then, Apr 15, 2021 I didn't know a scrap of Python...so I figure I'm solid ;D

[rare oar]

That's awesome man

I'm actually along similar lines of work, primarily in franchise restaurant operations

[ionic raft]

So, always curious to hear about React. It's the tool I'm hearing good things about for the front-end and diagrams

[rare oar]

patterns are fairly similar to most businesses I find though

[ionic raft]

Oh really...
LanesFlow has a subscription tier for Consulting Agencies...

OK...I may be pitching you at some point. Interested in being an alpha tester?

[rare oar]

Sure. I don't have decision making power for an app like this in full disclosure. Mid-level management here working on behalf of the franchisor

[ionic raft]

Hey...that won't matter...Friend req incoming. I'll follow up in a few weeks...

[native tide]

hey i have question how to use postgresql on django? i have been trying and download everthing like libpq-dev and still i can't use postgresql on django. Please help!, thanks

[rare oar]

is psycopg2 not installing for you?

[native tide]

i have been instaled and this happening when i type 'python manage.py makemigrations'

[rare oar]

can you post your urls.py? Doesn't sound postgres related tbh

[rare oar]

sorry your post/urls.py

[native tide]

it's still empty i just wanna prepare for database

[rare oar]

rename urlpattern to be urlpatterns

That will atleast allow it to go past that first error

[vestal hound]

delete that screenshot

and change your secret

paste errors as text

screenshots are hard to read

[vestal hound]

see this

[rare oar]

Ok so there's your postgres error. Its saying it can't connect. Did you install postgres on your machine or are you running it in a container?

[native tide]

i installed but i can't opened idk why

[rare oar]

not a linux guy, but quick googling (and this would be distribution dependent) but make sure you start your service. an example I believe for ubuntu is pg_ctl start

ok repasting my earlier question so its not lost

Good day everyone, I am wondering how you all approach integrating your front-end with your back-end source without putting everything in the same project. For instance, looking to use React on a small portion of my site. How can I keep my React code in another project, but have easy access to development?

[native tide]

can i ask about d.js here

🤔

[rare oar]

#discord-bots

wait... d.js is a discord thing or no?

if not, then sure ask here

[native tide]

alright

const { Client, MessageEmbed } = require('discord.js');

module.exports.run = async(bot, message, args) => {

  var pingembed = new MessageEmbed();
  var editingembed = new MessageEmbed()
  editingembed.setColor("#40E0D0")
  editingembed.setDescription("Pinging...")
  const diff = Date.now() - message.createdTimestamp;
  let msg = (` 🏓  **|** Pong! **Bot Latency:** \`${diff} ms\``)
  pingembed.setColor('#ff7100')
  pingembed.setDescription(msg);
  message.channel.send(pingembed)
 

}

module.exports.help = {
  name: "ping",
  aliances: []
}
```for some reason this command wont work
no error is provided in the terminal either
This is my command handler: https://hastebin.com/rabatiqobe.http

and its javascript

[rare oar]

heh yeah that is a discord bot. #discord-bots is the right channel

[quasi field]

I don't know about you all, but my website is making me hungry I think I'm almost ready to deploy

[vestal hound]

define “project”

you mean like Git repo?

you might wanna ask this in #tools-and-devops too

this is quite a devops question

[rare oar]

ok I'll post there

but yes, essentially how to have them in different repos, but actively develop on them

[opaque vale]

Hey guys can someone show me some example code for getting a response dictionary and printing it to command line? for some reason when i execute print(reponse.POST) it prints a blank line

[inland oak]

oh, linux guy. that makes it quite easy

for ubuntu (and probably debian too) systems, all you need to install those additional packages

apt update
apt install -y python3-pip python3-dev libpq-dev postgresql postgresql-contrib curl
apt-get install -y build-essential

plus your pip should have installed psycopg2

pip3 install psycopg2

(This library will not install itself properly until you installed the apt things above)

and that's basically it. then all is left to insert the right settings for connections

i have as default sqlite3

DATABASES = {
    "default": {
        "ENGINE": os.environ.get("DB_ENGINE") or "django.db.backends.sqlite3",
        "NAME": os.environ.get("DB_NAME") or BASE_DIR / "db.sqlite3",
        "USER": os.environ.get("DB_USER") or "",
        "PASSWORD": os.environ.get("DB_PASSWORD") or "",
        "HOST": os.environ.get("DB_HOST") or "",
        "PORT": os.environ.get("DB_PORT") or "",
    }
}

but in .env file I rewrite them with those ones to conect to postgresql

DB_ENGINE=django.db.backends.postgresql_psycopg2
DB_NAME=postgres
DB_USER=postgres
DB_PASSWORD=postgres
DB_HOST='127.0.0.1'
DB_PORT='5432'

you should be obiously having setup password for your database

password postgres is bad one btw 😉

How do I make a script know how to type in a specific place (say the Discord chat box for example)?

[inland oak]

just use their API

every chat box is some channel

all you need to use their send function with providing in which channel to send the message

[inland oak]

you can find and use discord chat box without using their API though
all you need to use the necessary Xpath path(Because essentially Discord is a website in Google Chrome). but that would be ridiculous way to do that. With API it has no point

[strong merlin]

Plz anyone refer me a beginner project for django

[versed python]

Todo application obviously

A bit more advanced can be something like Spotify

With users and liking songs etc

[twilit needle]

would you guys recommend graphql or rest, especially if I were to build an api with python

after having some experience with python graphql server libraries, I found out that they are really young and not mature enough. It will still take some time.
However, graphql promises a lot more than rest

[strong merlin]

Thnx for referring

[versed python]

Yes python and graphql have not played together well yet. The worst thing is that support is moving very slow. I made a PR adding docs to a graphql library and it has not been merged 3 months now. It makes me sad how the community is missing out on such a good technology.

[ionic raft]

My recommendation...look for projects to build that solve valuable problems. If you've got an idea of the type of coding you'd like to do focus on that

Your project portfolio gives you something to show. The experience building those projects gives you depth to talk about

[gritty coyote]

[long jackal]

I am making a website with a game, and I want to add sounds to that game but the sounds seem a bit delayed and they can't overlap, the game can require a few sounds per second. But the sounds will not play, or initiate (as in if I hit something, a sound plays, but if I hit something else as the first sound is playing, it won't play the second sound, even after the first sound is finished) until the current sound has finished playing.

Code

var gameOverSound = new Audio('/audio/player_lose.wav')
var enemyHitSound = new Audio('/audio/enemy_hit.wav')
var enemyPopSound = new Audio('/audio/enemy_pop.wav')

// then in some loops
gameOverSound.play()
//...
enemyHitSound.play()
//...
enemyPopSound.play()

Was hoping to ask some advise, just taking my first early steps into Django and was wondering on best practice.

Where should the data manipulation occur, within the SQL or bring it out into Pandas

with a view to exposing the results to the end user

[tulip beacon]

hey guys, I have a problem in css of my website, I used position relative in the Todo List script, and when I click the add button on the top, it adds HELLO but also there is a blank space increasing in the bottom, which is the white area at the bottom of the image

[sturdy sapphire]

do you have a link to this page?

and what is the problem with the white part again?

what do you want it to be

what do you expect to happen

what happens when you add a new tag

there are also no html or css code shown

!paste

[lavish prism]

Pasting large amounts of code

If your code is too long to fit in a codeblock in discord, you can paste your code here:
https://paste.pydis.com/

After pasting your code, save it by clicking the floppy disk icon in the top right, or by typing ctrl + S. After doing that, the URL should change. Copy the URL and post it here so others can see it.

[tulip beacon]

.todo{
    position: relative;
    left: 290px;

this is the css

can someone help with this basic q on Flask in #help-candy

[tulip beacon]

when I type something and click on the add button, the white space increases, I dont want that to happen.....

is there any fix for that?

@sturdy sapphire what should I do?

[weak nacelle]

i think you should provide the html too for easier reference

[native tide]

I had watched a couple of videos about web development they told us that we must know javascript for it, is that true? or python can handle that

[inland oak]

yes, it is true.

I mean...

if you are backend web developer, then no, python is enough

but if you make back and front at the same time.

Then you need to know python and javascript at the same time too, preferably.

Technically you can make beautiful things even if you know only python + html + css

but knowing even a little bit of javascript will help anyway.

[native tide]

thanks

test_* is conventional way to name unit test functions

it is not in your case. you have a view function.

Guys should i learn django or flask? I have already know the basics of python

I want to use mongodb with it also

Which is more useful?

[sudden steeple]

I imagine that there's a way to hook mongo up to almost anything.

Flask is really easy to get up and running with

[versed python]

Django doesn't even have an official Mongodb ORM since its nosql.

Among flask and Django I'd recommend Django though it's a bit more difficult

But it gives you more out of the box

[inland oak]

MongoDB is used.

[versed python]

I'm sure it is

[inland oak]

it is just has totally a different usage from SQL databases

don't mistake one for another

[versed python]

Yeah you're right

Edited my initial reply :)

[inland oak]

if you know basics, better to start with using Sqlite 😉

good for beginners

[sudden steeple]

https://www.mongodb.com/blog/post/getting-started-with-python-and-mongodb

[lime frigate]

I already knew sql

[inland oak]

well, then it is fine to go with MongoDB, cool thing to know too

[lime frigate]

So i wanna expand my knowledge

So basically i shouldn't use mongodb with python?

[inland oak]

I still can't find a time to expand my knowledge in this direction 😭

[inland oak]

why not 😉 you can

there are libraries for python integration with mongo

multiple ones

[lime frigate]

So in conclusion.... should i learn flask or django😂

[sudden steeple]

You can write a basic flask server in 5m

try that and if you don't like it try django

[inland oak]

flask is good for starters, django is good for real work

[lime frigate]

Based on functionality?

[inland oak]

flask follows micro framework approach

you have nothing at the start and you add micro libraries of its functionality.

good for starting learning curve I guess

django is having batteries included approach

everything is already enabled, you are like train on the rails (hehe ruby on rails)

you need to navigate through its documentation a lot in order to not reinvent the wheel

[lime frigate]

So is there anything that one can do but the other cannot.

?

Smthg like shortcomings?

[inland oak]

mm there are things actually.

main difference = Django offers already made Admin/moderator thing easily being made

+its good ORM for SQL usage

for Flask you choose your own SQL ORM thing

Flask made recently a step to become Async friendly framework

it is a bit too fresh probably though

Django made a step too, but a bit behind, since it can't transfer its ORM to asyncness yet

[lime frigate]

Hmmm

[sudden steeple]

from flask import Flask

app = Flask(__name__)

@app.route('/')
def index():
    return '<h1>Hi There!</h1>'

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

That's a flask web server

[lime frigate]

Still needs some consideration

[inland oak]

usually people...

who don't choose Django...

they choose Fast API

it is sort of...

having a lot of things already enabled for you too, but from a different sphere

[lime frigate]

So which one do you prefer personally?

[inland oak]

Fast API is fully async friendly framework, without ORM already installed, but as far as I heard it has almost setup REST documentation tools

I tried only Flask, Quart and in love with Django

I work with Django extensively, but eyeing quite a lot Fast API

wishing to try Fast API

[lime frigate]

Hmmm i see......

I think i will go with Django then

Thanks for the info mate

I'm going to sleep now byeee

[sudden steeple]

Does anyone have experience sending mail from the backend?

Some of the stuff that I've read says skip doing it yourself through smtp and use a service like SendGrid instead

Does anyone know if this is good advice?

[inland oak]

I am in a nutshell

[dapper tusk]

my suggestion is to use ariadne for APIs these days, I have found graphQL much nicer to work with than rest

[inland oak]

https://fastapi.tiangolo.com/
fast api claimes the speed of Go

I wonder how true those words are

[dapper tusk]

it depends on how you measure and is a completely meaningless number

[inland oak]

anyway, when you are going to use some custom database connecting library, I think Fast API could work better than django perhaps

like GraphQL I guess, or async postgres library

[dapper tusk]

graphql is a replacement for rest, not for a query language

though afaik there are databases that support graphql

[inland oak]

as far as I heard I am supposed to get some database like Neo4j or something like that

for graphql

[dapper tusk]

no need

[inland oak]

hmm

[dapper tusk]

I have done a graphql API running on CGI using mysql as the db

it wasn't very fast (because cgi), but it does work

[inland oak]

considering multiple caching instruments, perhaps.

caching database requests with redis

caching incoming requests even earlier with varnish

enough of things to cache and speed up 😉

[dapper tusk]

now yes, there are databases that work well with graphQL, but well, you can use whichever one you want

web framework benchmarks are not a good way to pick a web framework

also, they are really easy to make misleading

[inland oak]

i like Django for simplicity to develop

fast and comfortable.

[dapper tusk]

yeah, Django is great

[inland oak]

rapid blazingly fast 😉

[dapper tusk]

everything you need has an existing solution

probably even a builtin solution

[inland oak]

like... when you are going to develop a web chat... there is Django channels thing and e.t.c.

[dapper tusk]

even ariadne has django integration, so you can use the django ORM for a graphql api

[inland oak]

yeah, I saw the guys in imagine had a template

to presetup django with GraphQL as an option

with already made 100% coverage

cools guys.

I think I saved for myself their example, just in case to dig whatever they made 🤔

[dapper tusk]

that is one thing where django feels a bit lacking compared to sth like springboot, testing. But at the same time, I did not do a lot of django automated testing, so it may be better and I just haven't found the correct solution yet

[inland oak]

I feel myself good, when testing in django

pytest

coverage

mypy if I wish

whatever else I need? everything works.

[inland oak]

if standard testing tools in Django aren't enough

they are extended with Django Rest Framework

it provides everything you need for testing of APIs I think

probably I guess it would be a bit contradictory to use them with GraphQL, or not 🤔

[inland oak]

I did not use springboot to compare though

what would you recommend as a backend besides python+django to cover most of other situations?

Go+Jin I think? / Springboot + Java ? Ruby on rails? Something else?

[dapper tusk]

I would not recommend springboot tbh

it is not better than django for most things

[random jolt]

Hello, so I'm a beginner and I need someone to please help me out as an accountability partner, we could be friends here and grow together . Thanks in advance

[dapper tusk]

what I really liked was ruby on rails, but that is actually resource hungry enough to matter

[inland oak]

Golang is quite recommended for devops people

since I go with being backend+devops

perhaps some Go backend could benefit me better, since it would benefit me being as devops too

[dapper tusk]

I am very opposed to some solutions go takes to problems (byte sequences are not text, no matter how hard you squint), but it is indeed a good language to know for devops

[gritty cloud]

whats that

i use graphene lol

[dapper tusk]

ah, it is similar

[inland oak]

plus Go is quite fast one 😉
it could be fill the niche

[dapper tusk]

if you need fast and web, there is rust

[gritty cloud]

i feel that python servers' speeds are fine

[dapper tusk]

yeah, haven't ever had any issues

but it has you write the schema and bind the resolvers to the schema, it does not generate the schema from a class

[gritty cloud]

see graphene

[dapper tusk]

couldn't tell you whether that's a better approach than writing the schema in python

[inland oak]

I am a bit worried that Rust is not even mentioned in any popular lists

I guess I will compare available job vanacies

in Rust and Go

to make a choice

[dapper tusk]

oh, for jobs for sure go

[gritty cloud]

i probably won't learn anohter language other than python and js

[dapper tusk]

Rust is still niche

[inland oak]

Bleeding edge technologies ;b

keep up with time and all these things

[gritty cloud]

speaking of which

[inland oak]

Golang will serve me better I hope to remain popular

[gritty cloud]

im using svelte nowadays

[inland oak]

or more like becoming a popular

since it only grows

[dapper tusk]

yeah, I recently tried svelte and I am a fan

the right mix of react components and old style MVC separation of concerns

[versed python]

ive been thinking about trying out svelte for my next project

do you like it? would you recommend it?

im a vue guy and svelte looks easy

[gritty cloud]

if you just need some basic routing then flask is the way to go

[limber laurel]

Yeah but when you start using even a basic database, I have a feeling django is easier to use

Because of migrations and no need for seperstely installing SQLAlchemy and things like Flask-Migrate

How to get requests from a drop down select box?

[true kernel]

Apps arent loaded yet??

django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.
This happened after I deleted my database, made a new one and set AUTH_USER_MODEL = "account.Account", account is my app and Account is a class in its models.py

[gritty cloud]

i wouldn't tamper with Django's auth stuff

but if you are

have you added apps to INSTALLED_APPS?

[true kernel]

i had to buiild a custom user model

it has something to do with my postgres table im sure

[gritty cloud]

and is your AUTH_USER_MODEL after INSTALLED_APPS?

[true kernel]

no its before

[gritty cloud]

there's your problem

the apps literally haven't loaded in yet

so django has no clue what your talking about

move AUTH_USER_MODEL to the end of the file or at least after INSTALLED_APPS

[true kernel]

I did, it still shows the same error

[gritty cloud]

have you ran the migration commands

[true kernel]

although your reasoning makes perfect sense to me

yeah

i just did, and same errors

[gritty cloud]

is your postgres server up?

[true kernel]

itis

[gritty cloud]

hm

[true kernel]

it worked

i actually had imported accidentally account before installed apps declaration

[gritty cloud]

happens to the best of us lol

[true kernel]

it should not have been a problem but

[true kernel]

to be honest, theres this weird thing happening with me

my files have erroneus lines that I dont remember writing

its almost spooky

[gritty cloud]

perhaps your computer is possesed

or maybe you drank too much caffiene

[true kernel]

its highly unlikely but, you know what they say

when you rule out the impossible, whatever remains, however improbable must be the truth

my laptop is possessed af

[gritty cloud]

ncie

nice

[gritty cloud]

sell it on ebay and don't mention its possesed. when it gets sold, share the reaction from the buyer

Does anyone here know how django's F() expressions work?

reporter = Reporters.objects.get(name='Tintin')
reporter.stories_filed = F('stories_filed') + 1
reporter.save()

The docs says that the F class overrides the standard Python operators, but I dont understand how. Like, is the assignment operator (=) overriden? Or how does the F instance know about which Reporters entry to look at, and even on which model should it search?

Also how can you just temporarily override operators?

[indigo kettle]

you can override some operators using some special class methods like __add__ __sub__...
https://docs.python.org/3/reference/datamodel.html#emulating-numeric-types

and you can define how that operator should work and what it should return

Hi is there some change in Github Policy today?

https://github.blog/changelog/2021-08-12-git-password-authentication-is-shutting-down/

[true kernel]

Hello

I made a custom user model, and i am facing the issue that password is not being encrypted when a new user is added

and im not even able to login with that new user

Alright so turns out you can only login when the password is hashed. They should have mentioned this in the docs.

[fossil rivet]

I just typed wrong password. then I tried to log in as token. I can't install cli even

[calm plume]

When you're trying to push in git, you can't use your password in git anymore

You'll need to use SSH or a PAT

[quasi field]

#help-kiwi If anyone would like to answer a simple question about Django templates

[ionic raft]

Just logged in. Do you still have that question?

[rare oar]

http verbs are confusing. guildconfig/{id} alters a config but can't change the id. Is that put or patch?

I'm thinking put since you need to supply the entire body?

[quasi field]

Yes I am still wondering if it's possible to have something like a 'global variable' that I can use in my templates, for now I have just changed it so that all mentions of the site title are in the base template html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>PyBlog - {% block title %}{% endblock %}</title> </head> <body> <p> <b><em>PyBlog - {% block page_title %}{% endblock %}</em></b> | Then in other templates I do this html {% block page_title %}{{ page_title }}{% endblock page_title %} where page_title is passed in as context from the page specific view function. Here is how that looks on the index page

[ionic raft]

Maybe have it in a file that you import into each view file?

Load it as a context within each view.

I am not aware of another way of doing this...

[quasi field]

Ahh ok, yeah I guess that is probably the simplest way to do it. I was wondering if there was some sort of way to pass it from the base template, but that will work too!

[ionic raft]

However, template inheritance does take care of presenting it front end. But the context var needs to be in every view. Importing it would save a bit of code

current year for the footer is a good use case for that. Although, I build the var in each view file. So I've not tried what I suggested.

[quasi field]

something like views.py ```py
from django.shortcuts import render, redirect
from datetime import datetime
...
DATE = datetime.today()

Is that what you do for the footers?

I suppose this will work, it's easy enough to just pass this as context in one of the views (I only have one views file right now anyways)

[ionic raft]

Sorry was afk. Yeah...pretty much. I'll load the global at the top, and then load the year as a variable through context. That way, the year will always be current.

Just finished dashboard prototype design today... I welcome any UX feedback...

[ionic raft]

To be specific, I use the following

import datetime as dt

CURRENT_YEAR = dt.datetime.now().year```

[quasi field]

Looks very clean! I would maybe move the Profile and Subscription buttons closer to the sign out button, I think it might be better to have one side of the header for Tools and resources and one side for account related actions. But over all looking very good! Is this all possible with just html / css / django? Or are you using Javascript etc..?

[ionic raft]

Just Django/html/css for now. Working with React/JS for the 8th app

[manic frost]

sounds like something that will break when the application is running as the year is incremented

it's not really supposed to be a constant

[ionic raft]

How so? When the year is calculated with each page view?

[ionic raft]

Fair point. I could de-capitalize. I originally had it that way ironically

[quasi field]

I guess if the server were running in production, and it's New Years Eve it would be a problem, is that what you mean?

[manic frost]

I mean, unless you restart the app exactly at 00:00 on Jan 1, it will think it's still 2021

[manic frost]

yeah

[quasi field]

ahh yeah that is a good point...

[ionic raft]

So I'd need to pull the year calc into each view function?

[manic frost]

yes

or, well, make a function

[ionic raft]

Right 🙂

Good to know. Ty

[quasi field]

Yoo check this out https://docs.djangoproject.com/en/3.2/ref/templates/builtins/#now

I love django already

There's a template tag for that

[ionic raft]

Lovely

[quasi field]

Oh these are nice... https://docs.djangoproject.com/en/3.2/ref/contrib/humanize/

Yes, Humanize is very useful.

Hi there, I'm trying to figure out how to configure a custom user for my DRF project. I have attached my directory structure.

I have created a custom user like so:

from django.contrib.auth.models import AbstractUser

class User(AbstractUser):
    pass

Added my application to INSTALLED_APPS:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'rest_framework',

    # custom apps
    'apps.api'
]

And tried to change the AUTH_USER_MODEL like so:

AUTH_USER_MODEL = 'api.User'

However, I'm getting the following error:

django.core.exceptions.ImproperlyConfigured: AUTH_USER_MODEL refers to model 'api.User' that has not been installed

I have tried many ideas, but it still won't work. Could you help me?

Thank you!

[versed python]

AUTH_USER MODEL='apps.api.User'

[native tide]

I also tried this and getting another error.
Fortunately, I have solved the issue by creating an __init__.py file in the models directory, and added the following line to it:

from .User import User

Then it worked.

Hi myself Onkar and I am working on a Django Project. I am working on implementation of encryption techniques. This is my first project in Django.
Can anyone help me with the file handling in Django?
Condition: I want to encrypt file in my system and then immediately give user the key and encrypted file. I have code for file encryption using Fernet. Now all I need is solution to how to open the file in Django site??

def generate_key():
    key = Fernet.generate_key()
    with open("secret.key","wb") as key_file:                          key_file.write(key)
          return key
def load_key():
    return open("secret.key", "rb").read()
# keygeneration done
# encryting the file
def encrypt(filename):
    key = load_key()
    f = Fernet(key)
    with open(filename, "rb") as file:
        file_data = file.read()
    encrypted_data = f.encrypt(file_data)
    with open(filename, "wb") as file:e
        file.write(encrypted_data)

# decrypting the file
def decrypt(filename):
    key = load_key()
    f = Fernet(key) 
    with open(filename, "rb") as file:
        file_data = file.read()
    decrypted_data= f.decrypt(file_data)
    with open(filename, "wb") as file:
        file.write(decrypted_data)

key = generate_key()
file = __File-Name__
encrypt(file)
print("Your file has been encrypted.")
print("Your key for encryption is: ")
print(key)
decrypt(file)
print("Your file has been decrypted.")

This is my encryption code

Hello i got doubts in django DRF

[proper iron]

I'm working on this book, https://pgjones.dev/tozo/, that I aim to show how to build a production quality web app with a Python backend and React frontend starting from scratch. As well as building the app it includes how to setup your local computer, remote repositories and deployment. It has a companion codebase, https://gitlab.com/pgjones/tozo and the app itself is live at https://tozo.dev.

I'd really like to talk to you if this is what you are learning at the moment - specifically I'd like to know if this book makes sense, what it is missing, and whether it helps.

[pliant shoal]

Hello everyone, This doubt is about Django REST framework.
I am currently building a web app API from scratch. I'm totally new to django and web development. I have three models and each of them are linked in this order 1-2-3. I have serialised the data like the below code.

what I actually want is to make a API output like below:

Models1 {
pass
model 2 {
pass
model3 {

    }
}

}

and i want endpoints like this :

/api/v1/anime
/api/v1/anime?genre=

models.py - https://gist.github.com/jokerhacker22/6951d8667a32b069708884a296357c28#file-models-py

serializer.py - https://gist.github.com/jokerhacker22/219453bf3fdcbbeed316b98ab04cfebd#file-serializers-py

I am looking forward to get help from the experts here.
thanks in advance

How to dynamically add / remove input fields in Django anyone help please ?

I am new in Django

[pliant shoal]

you mean adding and removing input fields in admin?

[thorny quartz]

i want to add and remove input fields in html using a button

like want to add a value then i have to click a botton to add a input field or if i want to delete a field then i can do that using a button

[pliant shoal]

that's some kinda intermediate level yet i'm also new in django

i can help with some basic one's

[thorny quartz]

then can you make this in html https://www.youtube.com/watch?v=6N4OmsfwfdU start from 11:30

[pliant shoal]

you are building this in front end?

i use django for backend only, tried react once for front end

[thorny quartz]

front end is for user and back end for us

that html page will be connected to sql to store values

[pliant shoal]

yeah

why not django admin or default cms?

[thorny quartz]

i didn't understand

[pliant shoal]

You are making a page which connects to the sql server where you can edit data like models right?

[thorny quartz]

yeah

i mean page will be connected to django as well sql for security

[pliant shoal]

Django default admin panel does this

connects to the database, you can view or edit data and you have security there

[thorny quartz]

because that's defult sql in django

default*

[pliant shoal]

you want to use any other database? like postgreSQL

you can do that easily

[thorny quartz]

i use postgreSQL alreday

[pliant shoal]

what database is used in settings.py only behaves there

[vestal hound]

you can't

well, you can, but not easily

that sort of dynamism would be much better done with JS

on the frontend

[thorny quartz]

idk JS 😢

[pliant shoal]

please someone answer this

[thorny quartz]

can i make using html only or I really need js

@vestal hound

??

[vestal hound]

?

I wouldn't tell you to use JS

if it wasn't necessary

HTML and CSS alone

only allow you to create static pages

[vestal hound]

I actually don't really get the question, sorry

[thorny quartz]

😢 😢 😢 😢 thanks for the help bro can you please suggest any video or page so i can learn that

[pliant shoal]

look at my models and serializer sir, i want to make API endpoint where my models should be nested

like 1-2-3

[vestal hound]

uh...

not really, sorry, I don't use those

[pliant shoal]

oh

[vestal hound]

nest the serializers

[pliant shoal]

how?

[thorny quartz]

ok thanks bro

[vestal hound]

class ModelASerializer(serializers.ModelSerializer):
    b = ModelBSerializer()

    class Meta:
        model = ModelA

class ModelBSerializer(serializers.ModelSerializer):
    c = ModelBSerializer()

    class Meta:
        model = ModelB

class ModelCSerializer(serializers.ModelSerializer):
    
    class Meta:
        model = ModelC
        fields = '__all__'

like this

[pliant shoal]

and one more thing sir

i want to make a querystring in api endpoint the query will be one of the objects in the model

[vestal hound]

can you elaborate

with an example

[pliant shoal]

let me sir

i am building a anime backend API

i have episodes models

season model which is foreign key to episode

and anime model which is foreign key to season

and as ya said i have made a enpoint like this /api/v1/anime/

where all anime will be displayed

here i want to filter anime which is higher in rating

rating, popularity , created_at and start_date

class Anime(models.Model):
    """Base Class for Anime models"""

    name = models.CharField(max_length=80, blank=False, null=True)
    slug = models.SlugField(max_length=50,help_text="Slug name", null=True)

    original_name = models.CharField( max_length=70, help_text="Original Name of the Anime(optional)", null=True, blank=True)
    description = models.TextField(help_text="Desription about anime.")
    cover_image = models.ImageField(upload_to="Anime/cover_images/", verbose_name="Anime Cover image")
    bg_image = models.ImageField(upload_to="Anime/bg_Images/", verbose_name="Anime Background Image")
    created_at = models.DateTimeField(auto_now_add=True)
    genres = ManyToManyField(Genre)

    rating = models.FloatField(
        validators=[MinValueValidator(0), MaxValueValidator(10)],
    )
    popularity = models.FloatField(
        validators=[MinValueValidator(0), MaxValueValidator(100)],
    )

    author = models.CharField(help_text="Author name of the anime", max_length=50)
    country_of_origin = models.CharField("Country Of Origin", max_length=20)
    start_date = models.DateField("Start Date")
    end_date = models.DateField("End date", null=True, blank=True)
    status = models.IntegerField(choices=RELEASE_STATUS, help_text="Current status of the anime")
    seasons = ForeignKey(Season, on_delete=CASCADE, related_name="animes")
    staffs = ManyToManyField(Staff)
    studios = ManyToManyField(Studio)

    def __str__(self):
        return self.name
    
    class Meta:
        ordering = ['id']
        verbose_name_plural = 'Animes'

[vestal hound]

WTGF

[pliant shoal]

my anime model

[vestal hound]

okay

so...

[pliant shoal]

i just want to filter the enpoint with querystring

[dry crater]

sounds cool

[pliant shoal]

Oh thnx

[vestal hound]

so like

if I get what you're saying...

you want to extract optional arguments passed in the query string

and possibly use them to filter the returned results?

[pliant shoal]

yeah yeah yeah

you are right

how to do that

https://tenor.com/bk7zm.gif

[vestal hound]

you can get them

from the request

request.query_params

that would be a good start

(in your view)

[pliant shoal]

class EpisodeViewSet(NestedViewSetMixin, ModelViewSet):
    queryset = Episode.objects.all()
    serializer_class = EpisodeSerializer

class SeasonViewSet(NestedViewSetMixin, ModelViewSet):
    queryset = Season.objects.all()
    serializer_class = SeasonSerializer

class AnimeViewSet(NestedViewSetMixin, ModelViewSet):
    queryset = Anime.objects.all()
    serializer_class = AnimeSerializer

this is my views

I tried this but don't have any idea how to present it in urls.py

from rest_framework.routers import DefaultRouter
from rest_framework_extensions.routers import NestedRouterMixin

from api.views import (AnimeViewSet, EpisodeViewSet, GenreViewSet, NewsViewSet,
                       SeasonViewSet, StaffViewSet, StudioViewSet)

router = DefaultRouter()

router.register('episodes', EpisodeViewSet)
router.register('season', SeasonViewSet)
router.register('genre', GenreViewSet)
router.register('news', NewsViewSet)
router.register('Staff', StaffViewSet)
router.register('studio', StudioViewSet)

class NestedDefaultRouter(NestedRouterMixin, DefaultRouter):
    pass

router2 = NestedDefaultRouter()

animes_router = router2.register('animes', AnimeViewSet)
animes_router.register(
    'seasons', 
    SeasonViewSet,
    base_name='episode-seasons',
    parents_query_lookups=['episodes']).register('animes',
    AnimeViewSet, base_name='episode-seasons-anime',
    parents_query_lookups=['season__episode', 'season']
    )

[vestal hound]

if you're using generic views

then

you need to use...filters

https://www.django-rest-framework.org/api-guide/filtering/

this

or write a non-generic view

[pliant shoal]

ok

thanks for the proper guidance and help sir

go ahead

[past delta]

so can you help me display the reference webpage

at least the webpage?

if you wanna display a webpage open the url in your browser?

I am completely new to using Flask but would love to finish creating a web application but I am a little stuck 🙂

[austere relic]

just ask

[valid charm]

@austere relic any ideas on my question above?

[austere relic]

I'm really sorry, but I've neither tried celery nor flask

[valid charm]

ok thanks

[livid mason]

Thanks, does anyone know how I can create quizzes using Flask with a nice interface that allows for users to click one of the options and see if the answer is correct? And have the ability to add questions too....

[austere relic]

sounds like something you can do purely client side

oh, except for adding questions

[livid mason]

True, I am just not too sure where to start with programming the functionality....

[austere relic]

well, you know how to make a header that says "QUIZ", which is a start

so what exactly are you in doubt about?

[livid mason]

Yes, I am not sure how to create an interface that as 4 different options come up in boxes and be able to select them. Or how to have a form where you can input in questions. I am really sorry, I am quite a beginner!

[pliant shoal]

Sounds cool

[austere relic]

Are you comfortable with HTML? JS?

[livid mason]

No, only really Python unfortunately, though I have messed around a little with HTML.

[pliant shoal]

Oh

😕

[austere relic]

alright well, you can get away without using JS

using the form element

https://www.w3schools.com/html/html_forms.asp

however, I don't know how flask handles forms, so can't help you with that

[pliant shoal]

[dusk portal]

i dont have any big issue but sometimes i face problems while i work in drf in making exceptions

local variable 'serializer' referenced before assignment```

@api_view(['GET'])
@permission_classes([permissions.IsAuthenticatedOrReadOnly])
def detailview(request,post_id):
    if Post.objects.filter(id=post_id).exists():
        try:
            q2=Post.objects.get(id=post_id)
            serializer=PostSerializer(q2,many=False)
        except Post.DoesNotExist:
            raise Http404("NOT FOUND")
    return Response(serializer.data)

[pliant shoal]

Can someone tell me how I make AUTH_USER_MODEL for my User model

I have app named api which is installed in settings and I have models directory inside the api directory and in models directory I have accounts.py file having User model

[versed python]

It happens because your try block fails then the raise is executed. After that the return Response gives that error since serializer is not defined at that point.

Move the return inside try

[dusk portal]

umm

done

[dusk portal]

1 shift ohk done

[versed python]

Create api/models/__init__.py and from .account import User inside it

[dusk portal]

now py AssertionError at /69/ Expected a `Response`, `HttpResponse` or `HttpStreamingResponse` to be returned from the view, but received a `<class 'NoneType'>

[versed python]

Yeah

Inside the except block you need to return something

Not raise an error

[pliant shoal]

Yesh thanks sir but I crrated accounts app inside api app for workaround for now

[versed python]

Django doesn't know how to convert exception to responses

[dusk portal]

ohh

[dusk portal]

can u change it on my code and give me

@api_view(['GET','DELETE'])

ohk btw one last question that is in my mind @versed python

btw fixed that exception error

[versed python]

yeah?

[dusk portal]

u can see code
In that q3 is to delete and my models are properly configured with foreignkey to identify which user is filling the form/post request
So i want only that user can delete only his/her Posts
I have done kind of same thing in e-commerce site so he/she can see only his/her order history
But it was ezz in that bcez i used for tag in html n all but in rest api we don't use html templates so how can i do that

@versed python
