#

the client stores it, not the server

#

scalability reasons, with a million users at a time storing all those cookies builds up

#

whether that really matters.... GWworkshopAkaShrug

#

so your server would simply take cookie, give jwt, then you are done no more storing no sessions, nothing. and the client just sends jwt on each req until they refresh or close tab or something which causes them to have to send cookie again, so mostly useful in a spa or something

silver shell Oct 27, 2020, 11:27 AM

#

@native tide so you are saying you would store session data inside your jwt?

native tide Oct 27, 2020, 11:28 AM

#

ive never actually used session cookies, what exactly are you trying to get at by 'session data'?

I have a problem...whenever I create any react project on my desktop..whenever I save changes in my vs code editor it does not automatically comes to the browser I always have to refresh first and then I am able to see the changes
This is not a problem as such since I am able to refresh manually and do my work but still

native tide Oct 27, 2020, 11:29 AM

#

if you used create-react-app it should autorefresh you or at least it does for me GWworkshopAkaShrug

#

you are running with npm start ye?

@clear arch whats the question

clear arch Oct 27, 2020, 11:56 AM

#

I made all the script src, href, img src, src static but it still doesn't work

#

I also did {% load static %}

native tide Oct 27, 2020, 12:02 PM

#

send the code

clear arch Oct 27, 2020, 12:03 PM

#

well I was following a course so I download the templet

#

should I paste it

#

!paste

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.

#

Set your static directory in settings.py STATIC_URL = '/static/' and store all of your static files in a static/ directory

clear arch Oct 27, 2020, 12:07 PM

#

STATICFILES_DIR and STATIC_ROOT did that

native tide Oct 27, 2020, 12:08 PM

#

and static_url?

clear arch Oct 27, 2020, 12:08 PM

#

STATIC_URL is '/static/' only

#

I didn't change it do I need to?

native tide Oct 27, 2020, 12:10 PM

#

what directory are your static files held in

clear arch Oct 27, 2020, 12:11 PM

want the error?

native tide Oct 27, 2020, 12:16 PM

#

guys im pretty new in this subject, someone can help me where to start?

#

I'm getting an error when I save to my serializer. The "username" gets saved to my model's email field, the "email" gets saved to my model's password. How can I solve this?

#Serializer
class UserSerializer(ModelSerializer):  # In DRF serializer validation is done serializer-side
    class Meta:
        model = Users
        fields = ["username", "email", "password"]

    username = CharField(...)

    email = EmailField(...)

    password = CharField(...)

Model (extends Django prebuilt User class)

class Users(AbstractUser):
    notebook = models.ForeignKey(Notebook, on_delete=models.CASCADE, null=True, default=None)
    USERNAME_FIELD = 'username'
    EMAIL_FIELD = 'email'

clear arch Oct 27, 2020, 12:17 PM

#

See those line numbers I made them all static still error is there

📎 error_django.PNG

#

It says Not Found in all of them

#

omg

#

@native tide I typed STATIC_DIR and forgot S omg

this debug oof

I have implemented a chat application using Django Channels. How do I now extend to use audio/video call? What I have searched for, people are saying about WebRTC but I can't find any resources (for Django).

#

From what I understand by reading is that you can also send video data to the server from Client A and then from server to Client B (but WebRTC is direct client a to client b, less latency).

#

Latency is not an issue here though, I am only trying to learn

summer wyvern Oct 27, 2020, 2:15 PM

#

Hi

#

there is no Manage.py file in my django directory

#

I have searched everywhere

#

hello?

livid isle Oct 27, 2020, 2:35 PM

#

Hey guys web dev noob here

#

what exactly is the difference between an API, Framework, and Library

#

im so confused

summer wyvern Oct 27, 2020, 2:35 PM

#

a Framework creates websites

#

web framework like Django or Flask

#

a Library is something you import

#

example: ```
import random
from time import sleep

livid isle Oct 27, 2020, 2:36 PM

#

yeah but you can interact with external databases and servers with APIs as well as libraries so whats the diff?

summer wyvern Oct 27, 2020, 2:37 PM

#

librarys are libraries of code

#

API connects to web such as Plex API will conecct to a Plex Server

#

or Pastebin API will connect to pastebin

#

so you can automate stuff

#

or find information

livid isle Oct 27, 2020, 2:38 PM

#

what about selenium?

summer wyvern Oct 27, 2020, 2:38 PM

#

that automates stuff

livid isle Oct 27, 2020, 2:38 PM

#

isnt that similar to Plex API?

summer wyvern Oct 27, 2020, 2:38 PM

#

I dont think so

#

Plex API connects to plex only and finds info from plex only

#

Selenium automates web stuff

#

like button pressing

livid isle Oct 27, 2020, 2:39 PM

#

what about the requests library?

summer wyvern Oct 27, 2020, 2:41 PM

#

idk]

#

never used that

#

recap

#

Web Frameworks - create websites and servers

#

Libraries - contain code which can be helpful when creating a project

#

API - connects to web apps on the internet to automate or find information

#

got it @livid isle

summer wyvern Oct 27, 2020, 3:00 PM

Hi
there is no Manage.py file in my django directory
I have searched everywhere

devout coral Oct 27, 2020, 3:10 PM

#

@summer wyvern just make a new project then copy the manage.py

#

You will need to change the project name but that is all

summer wyvern Oct 27, 2020, 3:11 PM

#

reinstall django?

#

I installed Django in a venv

devout coral Oct 27, 2020, 3:11 PM

#

Just make a new project. And do startproject so it generates the manage.py. Then copy that manage.py to the project you already have.

#

On a different project.

summer wyvern Oct 27, 2020, 3:12 PM

#

make a new Pycharm project

devout coral Oct 27, 2020, 3:12 PM

#

Yes

summer wyvern Oct 27, 2020, 3:12 PM

#

ok

#

and then do the command startproject

summer wyvern Oct 27, 2020, 3:39 PM

#

@devout coral

devout coral Oct 27, 2020, 3:53 PM

#

@summer wyvern You get this figured out?

summer wyvern Oct 27, 2020, 3:53 PM

#

no

#

I created the project

#

now what do I do

#

@devout coral

devout coral Oct 27, 2020, 3:55 PM

#

copy the manage.py file that is there to your project that is missing it

#

Then change the name of the project inside that manage.py file to match the current project

summer wyvern Oct 27, 2020, 3:56 PM

#

do I have to install django in the other project

#

there is no manage.py @devout coral

devout coral Oct 27, 2020, 4:03 PM

#

@summer wyvern How did you startproject without the django library installed?

summer wyvern Oct 27, 2020, 4:03 PM

#

I have installed Django again

devout coral Oct 27, 2020, 4:03 PM

#

ok?

summer wyvern Oct 27, 2020, 4:04 PM

#

'startproject' is not recognized as an internal or external command,
operable program or batch file.

#

I tried in both projects

devout coral Oct 27, 2020, 4:05 PM

#

That is not the full command to start a project. Is this your first django project?

summer wyvern Oct 27, 2020, 4:05 PM

#

yes

#

I have never used Django before

devout coral Oct 27, 2020, 4:05 PM

he never ran a django-admin command?

summer wyvern Oct 27, 2020, 4:07 PM

@summer wyvern Use that tutorial

#

It is really good and even goes into deployment

summer wyvern Oct 27, 2020, 4:12 PM

#

ok

#

thanks

vapid acorn Oct 27, 2020, 4:17 PM

#

Imagine having a blog and you have a text-area.
The user types in:
"This is so
cool"
Then you put the via post request data in a p tag like following
<p>{{text}}</p>

Oh no, the data is not formatted at all, and the p tag gives a f*ck that the text has \n and \r tags!
How would one handle this, is there like a format:true; or sth or should I use another tag?

#

The text I get out of the text area:
I have some\r\ndummy text\r\nto try with \r\nnewlines
(I printed the post-request content)

#

Ok i figured it out

#

white-space: pre-line ....

#

in a span

dapper tusk Oct 27, 2020, 4:22 PM

#

what I did is have a property on the Post object that gives you the text as a list of lines

{% for line in text %}
<p> {{line}} </p>
{% endfor %}

vapid acorn Oct 27, 2020, 4:25 PM

would work, thank you, but I think the solution I found on the internet is a bit more elegant

how can I write mongod query in while loop, for example

A related to B
B related to C
C related to D

and user enters A and D

then my program will output something like A>B>C>D

I have db str with fields "main", "relation", "second"
so when user enters a name (A) it will find in which main it is and then query it's second in loop till we able to find D

@vapid acorn have you tried using redirect method?

directly in urls.py (in the project, not the app)?

Guys when do we use django rest framework??

devout coral Oct 27, 2020, 7:10 PM

#

@sterile peak Whenever you want to make a rest api

#

@hazy night What exactly do you need help with. I do not understand the issue

sterile peak Oct 27, 2020, 7:12 PM

#

@sterile peak Whenever you want to make a rest api
@devout coral so with the help of django rest framework I can use django as a backend and reactjs for front end, am I correct

devout coral Oct 27, 2020, 7:13 PM

#

@sterile peak Yes but are you trying to make a website? Usually api's do not have a front end.

sterile peak Oct 27, 2020, 7:14 PM

#

@sterile peak Yes but are you trying to make a website? Usually api's do not have a front end.
@devout coral I mean I can use those API to get data from my db right?!

#

And show it to user using front end frameworks

hazy night Oct 27, 2020, 7:14 PM

#

@devout coral I’m built myself a contact page with yahoo’s stmp settings with name email and message content(finally just got it to work). But now When a user inputs their email to send a message to my email it HAS to be a yahoo email for me to receive it (gmail, live, etc does not work).

devout coral Oct 27, 2020, 7:14 PM

#

That is typically what an api is for but it seems like you are trying to just build a website. So if you just want a build a website with a front end and a backend just use plain old django

sterile peak Oct 27, 2020, 7:15 PM

#

@devout coral I’m built myself a contact page with yahoo’s stmp settings with name email and message content(finally just got it to work). But now When a user inputs their email to send a message to my email it HAS to be a yahoo email for me to receive it (gmail, live, etc does not work).
@hazy night I think it is due to some security settings , does Yahoo offer no other documentation to check it?

devout coral Oct 27, 2020, 7:16 PM

#

@hazy night You want the user to send you an email from your site.... ? Confusing. Give me some more context please.

Are you trying to set up a way for the users to send you a message through your website? If so you would not use the users email. You would use your backend's email to send you the email and ensure that your send an email to their email if you need to respond.

hazy night Oct 27, 2020, 7:18 PM

#

@devout coral Would I be able to dm you the code for my setting and views etc so you can see and point it out ? I’ve been on it for a week now and decided to reach out

#

Yahoo unfortunately is quite dry on documentation. Only really give me settings which is enough but I’m confused as why it’s not sending properly @sterile peak

devout coral Oct 27, 2020, 7:24 PM

#

@hazy night Sure

sterile peak Oct 27, 2020, 7:35 PM

#

@hazy night you've used Yahoo's SMTP settings so I think it would only work with Yahoo. To get it to work depending on user's emails then you need to incorporate other emails SMTP settings and then use them accordingly based on user jnput.

Anyways, I am not sure what exactly is you are trying to accomplish so I may be completely wrong.

devout coral Oct 27, 2020, 7:38 PM

#

@sterile peak Yeah there is no need to have the email come from the user directly and you would not be able to do it since you will not be able to authenticate to the smtp server unless the user gives you the password. What he needs to do is just have the messages be sent from the server and then have somewhere in the email body who it is from.

sterile peak Oct 27, 2020, 7:39 PM

#

@devout coral yes that's what I feel too! Did you take a look at his code

devout coral Oct 27, 2020, 7:39 PM

#

Not yet

sterile peak Oct 27, 2020, 7:39 PM

#

alright man, if you find it interesting please let me know too.

@snow sierra You do not delete migrations unless you are deleting the database
@devout coral there is another way..

#

i want add third row in table, how?? without any issues..

i mean Column in db table (Partners)

still python Oct 27, 2020, 8:05 PM

#

hi

devout coral Oct 27, 2020, 8:06 PM

#

@snow sierra All you had to do was add another property to that class and run migrations

#

The ORM would handle the rest

#

@still python Hello

#

@still python This is the channel for web development

#

No worries

native tide Oct 27, 2020, 8:22 PM

#

Am I doing this right?

A user signs up on my website via an API. The API provides them a token for token auth. Then that token is stored in a cookie and on any future requests (as long as the cookie is there) the token will be placed in the header of my client requests

zealous siren Oct 27, 2020, 8:29 PM

#

@sterile peak Consider lighter framework for pure Rest API like Flask/FastAPI

snow sierra Oct 27, 2020, 8:40 PM

#

@snow sierra All you had to do was add another property to that class and run migrations
@devout coral i said it does not work man... i just added column manualy in DB.... bye.

devout coral Oct 27, 2020, 8:41 PM

Because you deleted your migrations... you would need to delete your database then re run the migrations.

@sterile peak So would i have to add all the smtp settings for multiple types of emails for a user inputted email to be sent to my email?

so its a contact page, user writes email and their name plus message and i receive their email (to my email). its only working with yahoo emails at the moment though is my issue im not sure if im explaining poorly

#

that's good

#

http://217.80.251.202:8010/site/

snow sierra Oct 27, 2020, 9:18 PM

#

where it is hosted?

vapid acorn Oct 27, 2020, 9:18 PM

#

on my computer

#

currently

#

but I think I will move it to my Raspberry PI

snow sierra Oct 27, 2020, 9:18 PM

#

is not bad idea

#

what type of server?

vapid acorn Oct 27, 2020, 9:19 PM

#

I use django and just do runserver 0.0.0.0:8010 with portwarding

snow sierra Oct 27, 2020, 9:19 PM

#

nice :)))

vapid acorn Oct 27, 2020, 9:20 PM

#

But I really struggle making sites look good

#

and i use noip.com to get and domain (instead of the long ip with port) also so my ip doesnt change

snow sierra Oct 27, 2020, 9:22 PM

#

for testing is good ..

#

can you try run games in browser windows?

vapid acorn Oct 27, 2020, 9:23 PM

#

yeah, the domain isnt beautiful tho (blabla.hopto.org) but who cares

snow sierra Oct 27, 2020, 9:23 PM

#

no one 😄

vapid acorn Oct 27, 2020, 9:24 PM

#

oh I thought about that (btw im on ubuntu) but they are pygame and not js games, which would be easier

#

I will look into that though

devout coral Oct 27, 2020, 9:27 PM

#

@vapid acorn Oh it is being blocked in my network

vapid acorn Oct 27, 2020, 9:28 PM

#

maybe because it is http not https

#

or just because it isnt in like a google index or sth

snow sierra Oct 27, 2020, 9:28 PM

#

tor it @vapid acorn

vapid acorn Oct 27, 2020, 9:29 PM

#

what do you mean?

snow sierra Oct 27, 2020, 9:29 PM

#

oops.. wrong chat

vapid acorn Oct 27, 2020, 9:29 PM

#

oh ok lol

devout coral Oct 27, 2020, 9:35 PM

#

Yeah because it is not indexed.

vapid acorn Oct 27, 2020, 9:36 PM

oh ok thanks

Is there a way to import bootstrap into a custom css file?

native tide Oct 27, 2020, 9:43 PM

#

@import url("stylesheet")

#

pretty sure this should work

bright spindle Oct 27, 2020, 9:44 PM

#

how do i serve a single static file in caddy for a directory like url/path/

#

theres barely any guides online

gentle ingot Oct 27, 2020, 9:44 PM

#

@import url("https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css");

.primary-btn {
    color: white;
}
``` This doesnt change the color of my button text to white. Am i importing it wrong😅

#

wait. i forgot to add the style sheet to my html 🤦‍♂️

devout coral Oct 27, 2020, 9:45 PM

#

@gentle ingot remove the import and change it to.

.primary-btn {
    color: white !important;
}

#

And it is a good idea to import the css lol

native tide Oct 27, 2020, 9:46 PM

#

!important override the cascade?

#

@devout coral

#

woops

devout coral Oct 27, 2020, 9:47 PM

#

Uhh what?

snow sierra Oct 27, 2020, 9:47 PM

#

!important! will always first and important for your css

native tide Oct 27, 2020, 9:48 PM

#

"!important override the cascade?"

snow sierra Oct 27, 2020, 9:48 PM

#

lol, little bich bot

native tide Oct 27, 2020, 9:48 PM

#

im pretty sure i learned this but it was so long ago and i never used it

devout coral Oct 27, 2020, 9:48 PM

#

Yes, it seems that is what he wants to do. Override what the primary-btn color is

native tide Oct 27, 2020, 9:48 PM

#

cant u just use SCSS or something to change it?

#

or SASS

devout coral Oct 27, 2020, 9:49 PM

#

Yeah but that would require to download bootstrap locally change it then compile it

native tide Oct 27, 2020, 9:49 PM

#

yeah...

#

and?

snow sierra Oct 27, 2020, 9:49 PM

#

also you can in html without any imports... <button style="color: white;")</button>

devout coral Oct 27, 2020, 9:49 PM

#

He is clearly using the cdn...

native tide Oct 27, 2020, 9:49 PM

#

ik

#

But i just think its not a great solution.

devout coral Oct 27, 2020, 9:50 PM

#

So why have him go through the trouble of downloading it changing it, compiling it etc.

native tide Oct 27, 2020, 9:50 PM

#

i mean its up too him

#

but if i was building production code its not what I would go with

devout coral Oct 27, 2020, 9:51 PM

#

Yes it is up to him, if he is setting up a legit server yes he would have the local bootstrap copy change/add everything he needs for his application and go with it.

#

But it does not seem his main worry right now is this, you are correct though. Good Quality production code should go through the process of downloading, changing, compiling.

gentle ingot Oct 27, 2020, 9:52 PM

#

Im just going through CS50 lmao. Didnt want to use inline styling if i could update what i needed to change in a css file

devout coral Oct 27, 2020, 9:53 PM

#

CS50 will not expect you to download the boostrap scss. I suggest to go with the easier approach and include a !important

gentle ingot Oct 27, 2020, 9:56 PM

#

Figured out why it wasn't working. My a tag was changing the color not the button

devout coral Oct 27, 2020, 9:56 PM

#

@gentle ingot You have a button wrapped in an <a> ?

gentle ingot Oct 27, 2020, 9:57 PM

#

I have the text wrapped in <a>

#

<button type="button" class="btn btn-primary"><a href="images.html">Image Search</a></button>

devout coral Oct 27, 2020, 9:57 PM

#

Why are you doing that exactly? For the button appearance?

gentle ingot Oct 27, 2020, 9:58 PM

#

Yeah the button tag is to make it look like a button and the a tag is to link it to the other page (havent learn js yet)

devout coral Oct 27, 2020, 9:58 PM

#

Do the following instead

<a class="btn btn-primary" href="images.html">Image Search</a>

#

The button styling can be applied to any tag basically

gentle ingot Oct 27, 2020, 9:58 PM

#

Huh, i guess that would be better since theres no real button functionality

#

Thanks

devout coral Oct 27, 2020, 9:58 PM

#

YW

#

Is this pure html, css right now? Or are you building this with a backend?

#

Just curious

gentle ingot Oct 27, 2020, 10:16 PM

#

Pure html and css

trim star Oct 27, 2020, 10:16 PM

#

Is it a good idea to list supported file upload types on a web site? Or is that divulging too much information?

gentle ingot Oct 27, 2020, 10:16 PM

#

Project 0 included python but like. Its an overview and not useful within context of the course

devout coral Oct 27, 2020, 10:20 PM

#

@trim star Why not include it? I would say include it.

#

@gentle ingot Well good luck

trim star Oct 27, 2020, 10:21 PM

#

@devout coral ok cool

#

Also, what is the best way to check that an uploaded file truly is in a supported format? I was thinking of reading a few bytes of the file header natively

snow sierra Oct 27, 2020, 10:23 PM

#

it has many ways.

trim star Oct 27, 2020, 10:24 PM

#

@snow sierra Well what currently happening in the project that I am contributing to is that they are just checking the content type of the request...but that can be bypassed, right?

snow sierra Oct 27, 2020, 10:25 PM

#

example:

def validate_file_extension(value):
if not value.name.endswith('.pdf'):
raise ValidationError(u'Error message')

trim star Oct 27, 2020, 10:26 PM

#

@snow sierra Thats worse than checking the content type right? Someone could just change the file extension

snow sierra Oct 27, 2020, 10:26 PM

#

from FORM?

devout coral Oct 27, 2020, 10:26 PM

#

@trim star By default django only checks the file extension. You can add some fancy stuff to try and read the file itself and see if it matches what you are looking for.

snow sierra Oct 27, 2020, 10:26 PM

#

did you use Django forms or HTML?

trim star Oct 27, 2020, 10:27 PM

#

@snow sierra they are using django forms

snow sierra Oct 27, 2020, 10:27 PM

#

it has own security i guess

#

but let me test something

trim star Oct 27, 2020, 10:27 PM

#

These are some of the things I am talking about: https://owasp.org/www-community/vulnerabilities/Unrestricted_File_Upload

Unrestricted File Upload on the main website for The OWASP Foundation. OWASP is a nonprofit foundation that works to improve the security of software.

native tide Oct 27, 2020, 10:29 PM

#

i could have sworn to god django automatically checks files not just extension?

gentle ingot Oct 27, 2020, 10:29 PM

#

Sorry for the ping misread the comment.

trim star Oct 27, 2020, 10:29 PM

#

@native tide I thought that too

devout coral Oct 27, 2020, 10:29 PM

#

@native tide Nope it only checks the extension

native tide Oct 27, 2020, 10:29 PM

#

¯_(ツ)_/¯

devout coral Oct 27, 2020, 10:29 PM

#

Let me double check

slender moat Oct 27, 2020, 10:29 PM

#

hey guys, does anyone know how i should deserialize with marshmallow, a database model that in one of its fields contains another database model?

#

There is a FileExtensionValidator but they specifically tell people not to rely on it as someone could just change the file extension

native tide Oct 27, 2020, 10:30 PM

#

Also someone needs to build a better CAPTCHA library with images not just fucking text

slender moat Oct 27, 2020, 10:30 PM

#

because right now, it's only deserializing the "root" object, and the nested objects don't get unpacked

native tide Oct 27, 2020, 10:31 PM

#

lol...

#

they are using regex

devout coral Oct 27, 2020, 10:31 PM

#

Yeah.

native tide Oct 27, 2020, 10:31 PM

#

i mean i guess it gets the job done

#

But I remember my teachers telling me not to use regex for this sort of stuff...

devout coral Oct 27, 2020, 10:32 PM

#

I mean if someone uploads a shell script but the file extension is .pdf what are they gonna do with that?

native tide Oct 27, 2020, 10:32 PM

#

*programatic parsing"

#

Well it depends.

#

on so many things

#

might be able to execute it from with in the website by just searching it

#

u never know

devout coral Oct 27, 2020, 10:33 PM

#

How will they execute it though if it has a .pdf extension?

native tide Oct 27, 2020, 10:33 PM

#

...

#

good point lol

devout coral Oct 27, 2020, 10:34 PM

#

They would need direct access to the file system in order to change that

#

and if they gained access to the file system you probably have bigger issues lol

native tide Oct 27, 2020, 10:34 PM

#

Can I ask what u do snowball?

trim star Oct 27, 2020, 10:34 PM

#

Yes, but its still an issue in my opinion even though there would need to be another vulnerability present

native tide Oct 27, 2020, 10:34 PM

#

U can easily implement ur own method for doing it

#

all ud have to do is check the header wouldnt u?

devout coral Oct 27, 2020, 10:35 PM

#

@native tide Sure... I am a month away from being the IT Manager at the company I work for.

native tide Oct 27, 2020, 10:35 PM

#

i could wipe something up like that in 15-20 minutes probs less

#

yay!

trim star Oct 27, 2020, 10:35 PM

#

@devout coral there could be a case where other vulnerabilities are present that can change file names/execute files

native tide Oct 27, 2020, 10:35 PM

#

Congrats mate

#

IT or CS?

#

or self taught

devout coral Oct 27, 2020, 10:36 PM

#

Thanks bro, self taught got me the job. But I went back to school and I finish next fall (IT).

snow sierra Oct 27, 2020, 10:36 PM

#

it is very low level trick... i think django form default can handle like this tryies

native tide Oct 27, 2020, 10:36 PM

#

Django seems pretty robust from what i've seen

devout coral Oct 27, 2020, 10:36 PM

#

@trim star But then those are other vulnerabilities... I do not think you should worry too much about this tbh

trim star Oct 27, 2020, 10:36 PM

#

U can easily implement ur own method for doing it
@native tide Yep! thats what Im thinking of doing...safely reading the first few bytes of the file to check file type

native tide Oct 27, 2020, 10:36 PM

#

and for the most part i think u need to try to make it insecure "excluding js"

devout coral Oct 27, 2020, 10:37 PM

#

@native tide May I ask what you do?...

native tide Oct 27, 2020, 10:37 PM

#

I mean actually u only need maybe 5 lines of code.

#

Nothing lol

#

I study everyday

@trim star But then those are other vulnerabilities... I do not think you should worry too much about this tbh
@devout coral I know Im being paranoid lol

native tide Oct 27, 2020, 10:38 PM

#

@trim star
I don't think ur being paranoid

#

I'd implement one too tbh

#

just need to check to see its got the header of the file u actually want

#

if it doesnt delete it

devout coral Oct 27, 2020, 10:38 PM

#

What sort of experience in web development do you have?

native tide Oct 27, 2020, 10:38 PM

#

legit 5 lines of code lol

#

Not much

#

legit just front end for the moment

@mortal mango incorrect path (my first opinion)

native tide Oct 27, 2020, 10:41 PM

#

Most likely just in the wrong directory/pointing to the wrong file.

devout coral Oct 27, 2020, 10:41 PM

#

@native tide The problem I find with flask is that if you are going to make a website might as well use django since you won't need to install everything individually

native tide Oct 27, 2020, 10:41 PM

#

I think it would be good for micro services

#

Like if you need to build a separate site for payments.

hybrid bobcat Oct 27, 2020, 10:41 PM

#

i need help with a package called django-spirit ;-;

native tide Oct 27, 2020, 10:41 PM

and then redirect too it.

devout coral Oct 27, 2020, 10:41 PM

#

@native tide I think flask is the king of microservices tbh

snow sierra Oct 27, 2020, 10:42 PM

#

flask is a mother of python web :d d

native tide Oct 27, 2020, 10:42 PM

#

I'd probs not even bother though.
I'd just build a backend service using python and then

#

well

#

allow django to talk to it

devout coral Oct 27, 2020, 10:42 PM

#

The overhead for it is small compared to django. Once you add all the functionality that django has though the performance difference is negligible.

native tide Oct 27, 2020, 10:42 PM

#

Yeah well

#

u can scale with anything

#

It doesnt matter what ur using long term

#

because scale is more about u and what ur doing in other places.
Like ur infastructure is just as important

devout coral Oct 27, 2020, 10:43 PM

#

Yeah, but I think the selling point of django is just development speed. If you know it you can whip up a site in no time

native tide Oct 27, 2020, 10:43 PM

#

I mean u gotta optimize code for it but...

#

How long do u think u could put together an ecommerce site?

#

like the backend

I thinking ima just highly customize a framework like bulma/bootstrap using sass

so it doesnt like like im using it

#

and then add extra classes if i need them

devout coral Oct 27, 2020, 10:47 PM

Well I actually maintain a SQL database in my day job so I know a good bit about SQL server but I am not a wiz making manual queries

#

Linux I only really know ubuntu

#

But server wise I maintain a few Microsoft servers

#

And yes my current IT Manager refuses to switch over to Microsoft Server 2016 from 2008R2 at one of the locations (do not ask me why, this is why they are having him retire lol)

#

@native tide Yeah, but I really wanted the shadow effect. I did not like what I had before which was greyish background and the white boxes.

@devout coral one more Languages for website..

devout coral Oct 27, 2020, 11:06 PM

#

@snow sierra Yeah that is tough. I remember when I was doing some IT consulting for a church they wanted a website built Spanish and English the firm that was doing the wesite design was basically charging double for the site since they would simply translate everything and build another site. Not sure if that is how you are supposed to go about it but that is what that firm was doing.

i never used include(file) in path() .. 1 more step in my mind

devout coral Oct 27, 2020, 11:13 PM

That the urls.py for the project (the one with all the includes) should be in the same directory as settings.py?

Please help me or I might punch my screen.

devout coral Oct 27, 2020, 11:14 PM

@snow sierra Oh yeah, I do that to better organize the project. This project is not small so if I put everything in the projects urls.py it would be hectic to decipher

That the urls.py for the project (the one with all the includes) should be in the same directory as settings.py?
@devout coral i mean it is new for me .... i don;t know is it better or not 😉 just good idea

devout coral Oct 27, 2020, 11:15 PM

Oh yeah, it makes sense if you have multiple apps to better organize code

#

I currently have 3 apps and v2 will have 4 apps. v3 will have 5.

#

Imagine having all those routes in one file lol

snow sierra Oct 27, 2020, 11:16 PM

also we can , **** from other_project import urls as u1 ****

of course it is very good for big projects , but i must start write like that 😉

in my little projects too ..

OK.. lets see Adam's issue :/

Why isn't nodemon working anymore???
I installed it like 2 days ago and now when I try and use it it won't restart the server after saving my code????
@raw imp don't know :X fckin node :d does it run in Virtualenv ??

devout coral Oct 27, 2020, 11:23 PM

@snow sierra not sure why you would have multiple projects in one. If you want to first get split up your project that is what apps are made for.

raw imp Oct 27, 2020, 11:24 PM

#

I'm super confused... it was working fine a few days ago. I havn't changed anything with the nodemon setup.
Just stopped working.

I tried removing all the node_modules and reinstalled all the dependency's. But that doesn't make a difference.
Looks like it isn't even installing, yet it can be run using npx nodemon -v

lol like i said before

#

there is no problem with it looking like bootstrap

#

Customers dont know

#

unless ur a web dev...

devout coral Oct 27, 2020, 11:31 PM

#

Yeah I know, but the first design just looked bad.

native tide Oct 27, 2020, 11:31 PM

cause of bootstrap?

devout coral Oct 27, 2020, 11:31 PM

The blue buttons the alignment

All of that

yeah it looks dreadful

#

how much did u change css wise?

#

i think the main difference is more layout

devout coral Oct 27, 2020, 11:34 PM

#

CSS wise a bit not too much. The biggest thing I guess css was the “cards” were not bootstrap cards and they had some animation which I removed.

#

The layout was the biggest thing.

native tide Oct 27, 2020, 11:34 PM

#

o lol

#

what sort of animation

#

was it the pop up thing

#

where u hover over it and it gets bigger

#

cant remember the effect name

bootstrap is great for having your layouts

its the standard

devout coral Oct 28, 2020, 12:08 AM

#

I would hate doing front end without bootstrap

native tide Oct 28, 2020, 12:23 AM

#

@native tide
u could use flexbot

#

in fact i think they might use flexbot

#

you mean flexbox?

#

or just use bootstrap... where you can have flexbox also

#

yeah rip typo

#

i dont know how the hell i got that confused

#

it happens

#

Bootstrap is OK i mean

#

I'm not a big fan personally.

#

I like smaller frameworks.

#

Something that only provides css components.
I think its better to use it so u dont have to reinvent the wheel and then just highly customise it.

#

and u cant rely on css frameworks for there js

#

@devout coral
As for your question about my projects.
I coded a mod manager (for minecraft) it was trash the code was dreadful and all it did was download files from curseforge and place them in a directory.
I also attempted implementing IRC but gave up on that for reasons I wont get into.

Right now im writing a noughts and crosses with network capability.
Was also going to turn it into a discord bot after posb.

I'd share my github but deleted it lol

Hello, anyone pretty good with Flask?

#

#

I'm sure there are a lot of people in this world who are pretty good with Flask yea

viral slate Oct 28, 2020, 1:07 AM

#

lol awesome, I'm going to try to start a Flask project and I was looking for someone for pointers

native tide Oct 28, 2020, 1:08 AM

#

what's the question

viral slate Oct 28, 2020, 1:10 AM

#

So I'm working on creating a table with stock information from pulling info from a .csv file and api call requests. Using pandas I'm able to pull the data that I want into a pandas dataframe, but I'm unsure of how to then pull the api data and combine it with the data that I have in my pandas df.

#

I already have a source and api for doing the calls so I've got the source of data figured out. I'm just unsure If I need to move my pandas dataframe into a sql database and then somehow add the api data or what...

native tide Oct 28, 2020, 1:15 AM

#

Ok, so you could have your API call for data, save that in a DB with a timeframe, then you can display that information. Then you can have an API to convert your pandas DF into your DB to combine the two data sources.

#

I wouldn't know how to go about that with Flask though, I'm not that good with it.

viral slate Oct 28, 2020, 1:17 AM

#

I haven't started with flask yet so I could go with django. I'm just trying to get the data for the table sorted out an then put it on django/flask. I just said flask because it looks more beginner friendly.

#

My question about the api data is that it is dependant on the stock tickers I have saved in my pandas df so it will know what to pull.

vestal hound Oct 28, 2020, 1:20 AM

#

@viral slate I'm confused

#

are you asking about combining the data or about how to build a backend/frontend using it?

viral slate Oct 28, 2020, 1:21 AM

#

Yeah, right now I'm working on the backend.

vestal hound Oct 28, 2020, 1:22 AM

#

okay

#

what do you want to do with it?

viral slate Oct 28, 2020, 1:24 AM

#

I have a downloaded csv file from my brokerage and then I use pandas too strip out the stock tickers, number of shares, and my cost basis. I'm using FMP api to call financial informaiton. I want to then pull info such as last price, etc. from using the stock tickers from my pandas dataframe and then turn that into a table for a web application.

haughty turtle Oct 28, 2020, 1:26 AM

#

On mobile right now but what does this return.

categories = Category.objects.all()

#

A list?

bleak bobcat Oct 28, 2020, 1:26 AM

#

A queryset

haughty turtle Oct 28, 2020, 1:27 AM

#

A queryset or set? I mean I could convert it to a normal set or list right?

bleak bobcat Oct 28, 2020, 1:27 AM

#

You can think of a queryset as a "list on which you can do database operations"

#

Not exactly accurate but enough to get the basics

haughty turtle Oct 28, 2020, 1:28 AM

#

categories = set(Category.objects.all())

#

I just want the list not perform any operations on them, would this work @bleak bobcat or I mean can I loop through that QuerySet just as I could a set or list?

bleak bobcat Oct 28, 2020, 1:29 AM

#

You can loop through it as you would a list, don't convert it unless you have a very specific reason to

haughty turtle Oct 28, 2020, 1:30 AM

#

Ok cool thanks

vestal hound Oct 28, 2020, 1:32 AM

Hey guys after a user signs up / logs in, I save a token as a cookie in their browser. Do I have the right design, where I will include this token as a header in each request to be able to distinguish between users (and therefore provide the correct content for each)?

@native tide yes

native tide Oct 28, 2020, 1:34 AM

Ok, thank you. I know that Django has some functions login(), logout(), but I have never used them and I believe they're based on sessions.

Since I'm using tokens this way, will those functions be useless?

@haughty turtle yeah, how do you want to use them?

@vestal hound

does anyone know a good resource for using Marshmallow library? the docs kinda suck

native tide Oct 28, 2020, 2:01 AM

@viral slate learning curve is lower but not by much. Django has inbuilt functions / models and other stuff which is easier to leverage compared to Flask, where you'll be looking at different libraries and different documentation to fill in what's not included (when compared to Django)

viral slate Oct 28, 2020, 2:02 AM

#

@native tide so do you think I should start learning by using Django?

native tide Oct 28, 2020, 2:04 AM

#

I personally don't think it matters. But if you want in-built functionality then go for Django. If you want more of a "free" experience use Flask. Whichever framework you learn, you get attached to it. I was attached to Flask and hated moving onto Django, but when I did I got attached to Django so it's my personal preference talking here

I am thinking something like this. Not sure how your models are set up but I think the concept still holds.

#

I hope I formatted that right. I’m on mobile so excuse poor indentation.

haughty turtle Oct 28, 2020, 2:24 AM

SLoC increases then, is there a benefit to using that concept over the one I have?

vestal hound Oct 28, 2020, 2:27 AM

@haughty turtle so you want one queryset each? or a big one

for loops in Django, unlike in pandas, are not almost always dodgy, but they can be

#

oh okay I didn't notice

#

your code

#

@vestal hound so you think I should take my pandas dataframe info and put it into a database and from there I'll be able to add columns from pulled api data?
@viral slate if you want it to be persistent, yeah

viral slate Oct 28, 2020, 2:33 AM

#

@vestal hound would I be able to do with without a database and just work within pandas and then make a table on the frontend with info from the dataframe?

vestal hound Oct 28, 2020, 2:33 AM

#

hm.

#

yes.

#

but what if your server goes down

#

how will you persist the data

#

@viral slate and will the dataframe be updated in realtime?

so yes?

to my question

viral slate Oct 28, 2020, 2:35 AM

#

I don't beleive realtime is required.

vestal hound Oct 28, 2020, 2:35 AM

#

okay, let me rephrase

#

will it be updated while the backend is online?

viral slate Oct 28, 2020, 2:37 AM

#

I don't beleive that is necessary. As my thought is that I'll upload a fresh csv file for the web app to pull the latest stock tickers from and number of shares

vestal hound Oct 28, 2020, 2:38 AM

#

okay, so what's your mechanism for updating the DataFrame in memory

viral slate Oct 28, 2020, 2:40 AM

#

That I'm unsure of. Right now I'm basically at scratch.

like you don't have to but it's a bit of an icky way to do things

#

IMO, at least

viral slate Oct 28, 2020, 2:42 AM

#

I'm going for the best method possible

vestal hound Oct 28, 2020, 2:42 AM

#

yeah.

#

you'd need to learn some SQL, most likely, though

#

or do you already know it?

viral slate Oct 28, 2020, 2:43 AM

#

I'll have to learn it. I have a dataquest.io membership for a year so I can hit up the SQL section. I'm just learning as I go.

#

I would like to know what you would think the smoothest route would be. From csv file to creating that table.

vestal hound Oct 28, 2020, 2:47 AM

remind me

#

what backend library are you using again

viral slate Oct 28, 2020, 2:49 AM

#

I don't have one set up at the moment. I'm trying to figure out the best route/path and go from there.

#

this is just some code that I have to edit down the csv to get the first few columns that I want to include in the table

I think I'll be leaning towards flask for the web development part

When you switch from home to games>brotastic, look at the change in highlight on the navbar.
@gentle ingot so you are using the nav bar for other templates and you want active bar to be highlight right? in template you can get the info of the url path with request.path to see which page you are on for example this is how i would do this in a jinja tempalte(used by django and flask framework):

{% if request.path == '/brotastic.html' %}
         <li class="nav-item active"><a>brostatic</a>
{% else %}
   <li class="nav-item"><a>brostatic</a>

this is an example but you can write your own if logic in the templates to render

in terms of the database, should they update their information everytime there's a change, or create new posts each time?

Why not make a variable then append that variable into a list

#

Dont work like that?

@merry copper try:
image_path_list.append(site_url + str(row))

@gaunt marlin it works!

#

Thank you!

gaunt marlin Oct 28, 2020, 3:33 AM

#

@native tide why would you make a variable and append it? when you can just append it? sound like 1 extra line and just create a random variable for nothing

native tide Oct 28, 2020, 3:34 AM

#

Make the code clear and understandable

gaunt marlin Oct 28, 2020, 3:35 AM

#

@native tide no it doesn't, to make code clear and understandable you can put comment in it

#

remember when you set a variable you assign it to an address in your memory, when you don't even use that variable for anything in the logic

#

so just wasted memory

native tide Oct 28, 2020, 3:39 AM

#

Variable are useful Don't say you don't even use that , variables have it own purpose and variables hold sensitive information which can be later it's not waste of memory . Clear variable make the code easier understand .

#

U don't understand the importance of variables

#

I can make my django project a rest api to use the data to make charts from javascript?
@plucky tapir yup!

#

@native tide why would you make a variable and append it? when you can just append it? sound like 1 extra line and just create a random variable for nothing
@gaunt marlin it depends.

#

I could see a reason to do that

#

shorter is not always better IMO

#

also the memory saving argument is p silly

gaunt marlin Oct 28, 2020, 3:43 AM

#

so you want him to do this ?

for row in image_path:
  image_url = site_url + str(row)     image_path_list.append(image_url)

i see no point in setting variable for this simple loop it's better if i put a comment to it

for row in image_path:
   # concat site url and image path
   image_path_list.append(site_url + str(row)  )

vestal hound Oct 28, 2020, 3:43 AM

#

unless you actually don’t use the value at all

#

yes

gaunt marlin Oct 28, 2020, 3:43 AM

#

well yeah you don't use the value at all in this logic

vestal hound Oct 28, 2020, 3:43 AM

#

I would prefer the former

#

although the variable names overall are weird IMO

gaunt marlin Oct 28, 2020, 3:44 AM

#

i don't set the variable name it's from the person asking

vestal hound Oct 28, 2020, 3:44 AM

#

like I would imagine a container for image_url would be called...image_urls...?

#

yeah, just a comment

#

IMO where you can express your intention in code or a comment

#

code is always better

#

as far as possible one should strive to write code that does not need comments

gaunt marlin Oct 28, 2020, 3:45 AM

#

it's opinions based, i see comment are more useful because python don't have to execute it(maybe my term is wrong because english is not my main language but you get what i mean)

vestal hound Oct 28, 2020, 3:46 AM

#

binding to variables has almost no cost

gaunt marlin Oct 28, 2020, 3:46 AM

#

comment are for the people that will develop on your code later in the future, even how simple your code is, having a comment always better for them to understand

#

or even for yourself in the future when you come back to the project

vestal hound Oct 28, 2020, 3:47 AM

#

comment are for the people that will develop on your code later in the future, even how simple your code is, having a comment always better for them to understand
@gaunt marlin not always. adding comments where they are unneccessary adds noise.

gaunt marlin Oct 28, 2020, 3:47 AM

#

yeah i don't mean comment on every line, just on some logics

vestal hound Oct 28, 2020, 3:48 AM

#

and

#

there are only two possibilities.

#

either your code can be understood just by looking at it, or it cannot.

#

in the second case, you could use a comment

#

but you should also think about whether there is a way to write it such that it is clearer

gaunt marlin Oct 28, 2020, 3:48 AM

#

if i remember correctly assign variable mean you binding name to an object in python. I usually work in C so pointer i'm familiar with

vestal hound Oct 28, 2020, 3:49 AM

#

if i remember correctly assign variable mean you binding name to an object in python. I usually work in C so pointer i'm familiar with
@gaunt marlin basically, there's a dict-like structure that has to be updated.

#

but like I said, the cost is so small that it is basically negligible.

#

sounds like a micro-optimisation to me

gaunt marlin Oct 28, 2020, 3:49 AM

#

yep

#

unless it's used i don't consider setting variable for it

#

not for something simple as a loop to append list

vestal hound Oct 28, 2020, 3:50 AM

#

honestly, in this case

#

I would prefer neither approach

#

and go with image_path_list = [f'{site_url}{row}' for row in image_path]

#

hm.

#

actually, no

#

yeah, that.

gaunt marlin Oct 28, 2020, 3:52 AM

#

yeah it can be easy as a list comprehension, but i know the person asking probably a newbie so i just post simple structure of it

merry copper Oct 28, 2020, 3:52 AM

#

you got it right

vestal hound Oct 28, 2020, 3:52 AM

#

the point is the f-string

#

as opposed to string concatenation

#

but well

#

I mean it's a relatively minor thing overall

gaunt marlin Oct 28, 2020, 3:53 AM

#

point taken

vestal hound Oct 28, 2020, 3:53 AM

#

and I feel like for a beginner

#

more steps might be clearer?

#

but yeah it's a code style question IMO

#

I'm personally super against comments

merry copper Oct 28, 2020, 3:54 AM

#

as a newbie, comments are what help me get through the lines of code

vestal hound Oct 28, 2020, 3:54 AM

#

because I think that if I need to write a comment I probz did something wrong

#

so I should refactor first

#

which is not something everyone agrees with

#

I think docstrings and architecture documentation >>>>> comments

gaunt marlin Oct 28, 2020, 3:57 AM

#

i worked in large project usually many people need to read other person code which write in the programming language they don't understand(maybe to implement the logic for their similar project). We always write comment for those purpose, i once need to implement another old codebase(from programmer who left the company) who wrote in typescript(which i haven't learn) to implement for python. So you can understand where it come in handy

vestal hound Oct 28, 2020, 3:58 AM

#

yup, I too have worked with other people on professional projects.

#

and IME

#

everything that was a comment

#

should have been one of these three:

better code
a docstring
external technical documentation

#

especially docstrings

gaunt marlin Oct 28, 2020, 4:00 AM

#

technical documentation is like a dream to have(once in a bluemoon on some project), but you understand it hard to come by where an old project has it

vestal hound Oct 28, 2020, 4:01 AM

#

yup

#

so I guess what I'm asking is

#

in the ideal case...would you want comments or proper documentation?

#

I'm not saying comments are bad

#

I'm saying that they are rarely the best solution

gaunt marlin Oct 28, 2020, 4:04 AM

#

i agree with you but i see that it's more important to use comment(not everyline, only on some difficult logic), as you see also in open sources people tend to leave comment on

@o0o0keem#9279 that is right

gaunt marlin Oct 28, 2020, 4:14 AM

Correct way to filter by match

#

and can I access a QuerySet from html passed into views, say I pass in 20 objects of Products, then in my html can I access product_names from Products

#

Got my first question answered

haughty turtle Oct 28, 2020, 12:31 PM

#

         <div class="product_categories">    
            {% for i in context %}
                <div class="product_category" id=i>
                    {% for p in context[i] %}
                       <div class="product_name" id=p.product_name>
                           <span class="product_price" id=p.product_price></span>
                           <span class="product_description" id=p.product_description></span>
                           <span class="product_photo" id=p.product_photo></span>
                           <span class="product_gener" id=p.gender></span>

                </div>
            {% endfor %}
        </div>```

is this correct

#

in the way I am grabbing my items from the QuerySet and putting id name as so from my QuerySet

#

gm are you senior? 😳
@native tide am I what?

vapid acorn Oct 28, 2020, 1:13 PM

#

@haughty turtle I think this way of assigning id's or class names to html objects is vurnerable

#

Because that part aint handled by django

haughty turtle Oct 28, 2020, 1:22 PM

#

I have to put them inside of double curly brackets right @vapid acorn

vapid acorn Oct 28, 2020, 1:22 PM

#

yeah

bleak bobcat Oct 28, 2020, 1:24 PM

#

Also, {% for p in context[i] %} what is that ? What is context here ?

haughty turtle Oct 28, 2020, 1:26 PM

#

Yeah I just got an error in that just now was going to comment on it

#

so context is a dict from my views

#

def index(request):
    context = {}
    categories = Category.objects.all()
    for i in categories:
        Prod = Product.objects.filter(category=i)
        context[i] = Prod  
    return render(request, 'product/index.html', context)```

#

Could not parse the remainder: '[i]' from 'context[i]'

vapid acorn Oct 28, 2020, 1:26 PM

#

but context should be like {"name":name_var}
and in code you can just access name

#

I wrote that before I saw your code

#

So just pass in a list as products, then loop through products and access them like product.name ...

bleak bobcat Oct 28, 2020, 1:31 PM

@haughty turtle show your Category model

bleak bobcat Oct 28, 2020, 1:36 PM

#

You're doing 1 query to get all categories, then for each of them you're doing another query to get its products, and then you store that in a weird way. Why not just get all the products from the start ?

If you need to group the products by categories when rendering them you can use https://docs.djangoproject.com/en/3.0/ref/templates/builtins/#regroup

haughty turtle Oct 28, 2020, 1:58 PM

#

@bleak bobcat is suggesting that I use regroup, trying to see the benefit, it was suggested to me I am looking into it and just seeing the pros and cons

devout coral Oct 28, 2020, 2:02 PM

#

Yeah... pre optimization normally leads to no benefits and a total waste of time and maybe more confusing code. I say take what you have and move on. There is one loop and one query to the database not terrible.

haughty turtle Oct 28, 2020, 2:20 PM

#

Ah ok got it now so your code does seem better optimized, it's only one line in my views.

context = {"products": Product.objects.all()}

{% regroup context by Product.category as category_list %}

#

But then I am still looping through the next list @bleak bobcat , does objects.all not only make one query call?

#

Providing me a list of all the categories, why would it make 3 calls?

#

I would still be making calls to the object in regroup, as I would with the ones in my list.

#

It's like saying if I have 5million products is object all going to make 5million query calls? That would be a bit silly as I thought it is providing me a list only one time ?

Anyone here know if there is a best practice on how to handle permissions for users?

Does anyone here know how to show image in FastAPI?

vapid acorn Oct 28, 2020, 3:30 PM

#

@devout coral If you are using django you can use the build in user model and if you need more than staff, superuser and normal user you can add more manually by modifying the model.
in -for example- your html you could do {% if request.user.is_staff%}<p>Hello mr staff </p> {% endif%}

devout coral Oct 28, 2020, 3:53 PM

#

@vapid acorn That is not what I am talking about. I am talking about the permissions for the user model.

#

This is what I have and there are more.

vapid acorn Oct 28, 2020, 3:54 PM

#

to access and modify the user db or what?

devout coral Oct 28, 2020, 3:54 PM

#

Not sure if there was a better way.

#

Do you know of the @permission_required decorator?

vapid acorn Oct 28, 2020, 3:55 PM

#

Oh sorry I really missunderstood your question at first

#

no sorry, haven't used that yet

devout coral Oct 28, 2020, 3:55 PM

#

It is not that this system is not working, I just want to know how other people do this and if there was a better way.

vapid acorn Oct 28, 2020, 3:57 PM

#

yeah, but I think I can't help you with that sorry

devout coral Oct 28, 2020, 3:57 PM

#

No worries.

class Product(models.Model):
    product_name = models.CharField(max_length=100)
    product_price = models.DecimalField(max_digits=5, decimal_places=2)
    category = models.ForeignKey(Category, on_delete=models.CASCADE)
    gender = models.ForeignKey(Gender, on_delete=models.CASCADE)
    product_description = models.CharField(max_length=250)
    product_photo = models.ImageField(upload_to='product')
    
    def __str__(self):
        return self.product_name``` @stable kite I got `Field 'id' expected a number but got 'Clothing'.` it seems that I got my category name correctly but category inside of my product model is represented as a number not a string

#

nvm

#

Was passing in the category name instead of the object itself

stable kite Oct 28, 2020, 4:17 PM

#

ok

haughty turtle Oct 28, 2020, 4:20 PM

#

Prod    
<QuerySet []>
categories    
<QuerySet [<Category: Clothing>, <Category: Accesories>, <Category: Textiles>]>
context    
{'Accesories': <QuerySet []>,
 'Clothing': <QuerySet [<Product: Test 1>]>,
 'Textiles': <QuerySet []>}
i    
<Category: Textiles>
request    
<WSGIRequest: GET '/'>``` but then this is my local variable, I am still getting `Could not parse the remainder: '[i]' from 'context[i]'` on `{% for p in context[i] %}` in my html code

#

I mean I try placing error handing with if statements it did nothing

#

@stable kite am I accesing the index in my dict incorrectly

stable kite Oct 28, 2020, 4:20 PM

#

@haughty turtle where did you this error?

#

@stable kite am I accesing the index in my dict incorrectly
@haughty turtle you can't access dictionary by index you have to use keys

haughty turtle Oct 28, 2020, 4:29 PM

#

thats what I meant had to rush out to do something, @stable kite but I am placing my keys and I do not know its not grabbing it it seems like

#

        <div class="product_categories">    
            {% for i in context %}
                <div class="product_category" id={{i}}>
                    {% for p in context[i] %}
                        {% if len(context[i]) != 0 %}
                           <div class="product_name" id={{p.product_name}}>
                               <span class="product_price" id={{p.product_price}}></span>
                               <span class="product_description" id={{p.product_description}}></span>
                               <span class="product_photo" id={{p.product_photo}}></span>
                               <span class="product_gener" id={{p.gender}}></span>
                           </div>
                        {% endif %}
                    {% endfor %}
                </div>
            {% endfor %}
        </div>```

#

I know I have two keys that are empty, so I have this if statement but still nothing

stable kite Oct 28, 2020, 4:32 PM

#

@haughty turtle you keys are string not ints

bright spindle Oct 28, 2020, 4:32 PM

#

is there anyone here experienced with caddy, caddycaddycaddy

haughty turtle Oct 28, 2020, 4:32 PM

#

ah

#

nvm

#

Nvm, blah my mind is all over the place, all this arguing with my wife... yes my keys are strings @stable kite are they not supposed to be

#

{'Accesories': <QuerySet []>,
 'Clothing': <QuerySet [<Product: Test 1>]>,
 'Textiles': <QuerySet []>}``` their stored as string in my dict, which then stores a QuerySet

stable kite Oct 28, 2020, 4:37 PM

#

but you cant iterate over dictionary

#

in your html

#

they aren't list

haughty turtle Oct 28, 2020, 4:38 PM

#

but in python I can iterate over dictionaries just fine @stable kite

#

for keys in dict: gives me the names of all my keys, it always has. Whats the difference in using this in Django

stable kite Oct 28, 2020, 4:44 PM

#

but in python I can iterate over dictionaries just fine @stable kite
@haughty turtle you can but it gives key not values

#

so you need access it like dict[key]

haughty turtle Oct 28, 2020, 4:47 PM

#

thats what I am doing @stable kite

#

{% for i in context %} <div class="product_category" id={{i}}> {% for p in context[i] %}

#

It grabs my keys in the first for loop and my error is in my second for loop

#

context[i] should give me my QuerySet and I am supposed to be looping through it

#

Is this HTML language ?

#

It's harder than Python

warm igloo Oct 28, 2020, 5:05 PM

#

that is templating code, Jinja for instance @native tide

native tide Oct 28, 2020, 5:05 PM

#

👍

warm igloo Oct 28, 2020, 5:06 PM

#

@haughty turtle Have you run a debugger and a breakpoint on those loops? You may not be getting what you think you should be getting.

haughty turtle Oct 28, 2020, 5:14 PM

#

Where would I run the debugger? If the code is basically in my browser ? @warm igloo

stable kite Oct 28, 2020, 5:14 PM

#

@haughty turtle got your mistakes

#

change your render code

haughty turtle Oct 28, 2020, 5:14 PM

#

What's wrong with it?

stable kite Oct 28, 2020, 5:15 PM

#

post your code

#

i will tell you

#

@haughty turtle try this

    context = {}
    categories = Category.objects.all()
    for i in categories:
        Prod = Product.objects.filter(category=i)
        context[i.category_name] = Prod  
    return render(request, 'product/index.html', {"context":context})```

haughty turtle Oct 28, 2020, 5:41 PM

#

You think so? @stable kite

from django.shortcuts import render

from .models import Question


def index(request):
    latest_question_list = Question.objects.order_by('-pub_date')[:5]
    context = {'latest_question_list': latest_question_list}
    return render(request, 'polls/index.html', context)``` In the django tuts they just pass the dict name in directly

Does anyone use flask?

#

I could use some pointers to proper design patterns. Especially involving initializing the database.
