What exactly does {% load static %} do?

What exactly does {% load static %} do?
@limber laurel it just loads your static folder... then you could just type {%static' urlinsidestaticfolder'%} as the url to get the files in it.

limber laurel Oct 25, 2020, 9:14 AM

#

Thanks

#

And if I for example had a media direcotry I could techinaclly load media the same way right?

stable kite Oct 25, 2020, 9:15 AM

#

no

#

you can't load media directory

nova nacelle Oct 25, 2020, 9:18 AM

#

like if there is an images folder inside the static folder... then you just type {%static 'images/name.format'%}.

#

And if I for example had a media direcotry I could techinaclly load media the same way right?
@limber laurel you can't load it... just have it in static folder.

limber laurel Oct 25, 2020, 9:22 AM

#

ok

nova nacelle Oct 25, 2020, 9:22 AM

#

@limber laurel you can't load it... just have it in static folder.
@nova nacelle and follow the {%static' '%} thing.

for example I have a excel file I upload it and convert it into dataframe and in the same view I change some data in the dataframe now I want that data frame to convert into excel and download it to user

response=HttpResponse(data.to_excel("a.xlsx"),content_type='application/vnd.openxmlformats-officedocument.spreadsheetml.sheet') response['Content-Disposition'] = 'attachment; filename=%s_Report.xlsx' % excel_file.name

@vivid canopy try removing the first slash in your href

vivid canopy Oct 25, 2020, 11:22 AM

#

i did it also with it but didnt work i can try it agian

#

nothing changed

#

this is maybe some error report from cmd "127.0.0.1 - - [25/Oct/2020 12:24:02] "[33mGET /demoapp/visualize/styl.css HTTP/1.1[0m" 404 -"

hey guys, when should i use breakpoints for responsiveness?
my homepage loooks fine at 500px now and i wondered when to set the media-queries

raw vortex Oct 25, 2020, 11:45 AM

#

@vivid canopy Have you tried something like <link rel="stylesheet" href="{{ url_for('visualize', filename='styl.css') }}" /> (you will need from flask import url_for)?

remote ruin Oct 25, 2020, 11:45 AM

#

added: i can use them whenever i want i know, but when is it best to use, are there some standards?

vivid canopy Oct 25, 2020, 11:47 AM

#

@raw vortex didnt try it but now i m reding something like in templates shouldnt be home or about page. bur thanks i will try it

#

it didnt worked

raw vortex Oct 25, 2020, 11:52 AM

Can I see what you tried to do?

vivid canopy Oct 25, 2020, 12:00 PM

me?

raw vortex Oct 25, 2020, 12:01 PM

#

Yes

vivid canopy Oct 25, 2020, 12:02 PM

#

okey so in about and home.hmtl is just h1 wich says this is home / about page

#

in styl. css is just body {background color grey}

#

this is index.html which can't connect rel to css idk why

📎 unknown.png

#

and if u want see this is main.py

📎 unknown.png

#

and this is what i get

📎 unknown.png

#

just that prob it dont want to connect with css

#

i already tried evrything

raw vortex Oct 25, 2020, 12:10 PM

#

What I would suggest is to have a different folder for your non-template files. For example, you can have:
demoapp ├── templates │ ├── index.html └──── assets └── css └── styl.css

vivid canopy Oct 25, 2020, 12:10 PM

#

i can try it but

raw vortex Oct 25, 2020, 12:12 PM

#

Then, you can change your linktag to <link rel="stylesheet" href="{{ url_for('assets', filename='css/styl.css') }}" />

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.

From that message

jinja2.exceptions.TemplateNotFound : inedx.html

What does that mean? In your code you tried to load a template caleld inedx.html but there is no such template.

#

Now find where you typed that.

And change it to what it should be

vivid canopy Oct 25, 2020, 1:07 PM

yes but i didnt call file template if i understand it right render_template calls file templates automaticly like u dont need to connect it with code like if u understand me

You tell it what it extends though

and rn you're telling it extends inedx.html

native tide Oct 25, 2020, 1:11 PM

And that extends is trying to load a template which doesn't exist.

mostly the top half

native tide Oct 25, 2020, 1:17 PM

@vivid canopy extends "template" adds your {% block content }% to that template. It's Flask template inheritance.
Read about it here to understand:
https://flask.palletsprojects.com/en/1.1.x/patterns/templateinheritance/

You tried to extend to a template which doesn't exist. "inedx.html" is not "index.html" so it's a typo. You could've changed the filename and it would've worked.

Hi!
Sqlalchemy page shows that I can work with sessions like that:

from sqlalchemy import create_engine
from sqlalchemy.orm import sessionmaker

# an Engine, which the Session will use for connection
# resources
some_engine = create_engine('postgresql://scott:tiger@localhost/')

# create a configured "Session" class
Session = sessionmaker(bind=some_engine)

# create a Session
session = Session()

# work with sess
myobject = MyObject('foo', 'bar')
session.add(myobject)
session.commit()

However, whenever I do session = Session() in my Flask app, the whole thing hangs.
For more context - I'm doing the engine and sessionmaker instance (Session) in my init file, and importing this Session into another file where I do session=Session().
I have been googling around and can't figure out what I'm doing wrong.

But how

fetch_guilds gives me an empty list

getting the username and profile picture works fine but getting guilds just does not work

pretty simple question, im running a quick and dirty Quart server to test the payload of another application, however i cant seem to print anything out to the console: ```py
from quart import Quart, websocket, request

app = Quart(name)

@app.route('/death')
async def hello():
print("test")
return 'hello'
app.run()

#

i can see something was posted but i cant get anything to print, be it the request, the payload, or anything else such as just 'test'

#

[2020-10-25 10:11:48,767] 127.0.0.1:60752 POST /death 1.1 405 137 997```

nova nacelle Oct 25, 2020, 5:21 PM

#

I guess because it returns 'hello'?

nova pendant Oct 25, 2020, 5:21 PM

#

?

nova nacelle Oct 25, 2020, 5:21 PM

#

wait.

nova pendant Oct 25, 2020, 5:21 PM

#

it should print before it returns anything

#

the second code box i sent is the entire console output, i need the request payload to print to the output but nothing is printing

nova nacelle Oct 25, 2020, 5:22 PM

#

okay i see it now... I'm really working so just paid half attention to that.

@vivid canopy in django you just add a STATIC_URL on settings and then on the template:

{% load static %}

{% static 'css/stlye.css' %} to load the css

native tide Oct 25, 2020, 7:07 PM

#

@vivid canopy CTRL + F5 in ur browser

#

resets browser cache and therefore css

toxic flame Oct 25, 2020, 7:07 PM

#

yea sometimes css doesn't load in real time for me

native tide Oct 25, 2020, 7:08 PM

#

bc it's saved in cache which needs to be reset for you to see updated code

hey guys, anyone works with FastAPI ? I have a question about the structure of a project, i would like to implement OAuth2 following this tutorial https://fastapi.tiangolo.com/tutorial/security/oauth2-jwt/ but i don't know where should i put my code for it, so for now i placed the source code at auth.py in the main folder but i don't know

📎 unknown.png

OAuth2 with Password (and hashing), Bearer with JWT tokens - FastAPI

FastAPI framework, high performance, easy to learn, fast to code, ready for production

native tide Oct 25, 2020, 9:58 PM

#

📎 unknown.png

#

I'm sending a request to my API and all my fields are empty. But, my serializer is only returning an error this field may not be blank for 2 out of 3 of my fields...

#

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

    username = CharField(max_length=20, allow_null=False, required=True,
                         validators=[UniqueValidator(queryset=Users.objects.all(),
                                                     message="Username is taken, try something else"),
                                     MinLengthValidator(4, message="Username is too short (<4 characters)")])

    email = EmailField(allow_null=False, required=True, validators=[UniqueValidator(queryset=Users.objects.all(),
                                                   message="An account with that email already exists")])

    password = CharField(allow_null=False, required=True, max_length=100)```

#

The password field isn't getting the validation. But the only difference is that it doesn't have the UniqueValidator validator... how strange

#

Anyone know how I can fix this?

#

I made a fix. In my serializer if any of my fields are empty it returns a dict with key error so in my JS I checked if the response object contains and error key and it will render one message saying that the form is incomplete, rather than a seperate error message for every field.

#

So yeah that's pretty much done. Now I need to do session auth and I don't understand it 😄

Is it possible in python/django to verify that a file extension matches its type?

#

I know in linux the file command does this but I want to avoid executing this command via subprocess if I can do it in python natively

vestal hound Oct 26, 2020, 12:41 AM

#

Is it possible in python/django to verify that a file extension matches its type?
@trim star what do you mean "matches"?

#

like whether a file with a particular extension is actually what it advertises?

trim star Oct 26, 2020, 12:41 AM

#

for example, verify that example.jpeg really is a file of type jpeg

#

Yes @vestal hound

vestal hound Oct 26, 2020, 12:41 AM

#

ah

#

I'm not sure if there's a library for that

#

there probably is

#

but if not, it's not a very hard problem, but it is a wide one

#

because the difficulty of verifying if a file is the type it's supposed to be varies, right?

#

e.g. how do you tell if a Python file is a valid one? you have to compile it.

#

but I guess you only want to do this for a specific set of extensions, right?

trim star Oct 26, 2020, 12:44 AM

#

@vestal hound yes

vestal hound Oct 26, 2020, 12:44 AM

#

@vestal hound yes

vestal hound Oct 26, 2020, 12:47 AM

#

okay

#

if you can't find a prebuilt solution

#

I'm sure each of these has some kind of header

#

you can open the file and check for that

trim star Oct 26, 2020, 12:52 AM

#

@vestal hound yes. I think security wise if I cannot find a well supported solution, then doing that myself in native python is better than calling subprocess and more platform independent

@native tide from your flask view, you can pass context variable to template, and in the template you can use {{ variable }} anywhere for example:

@gaunt marlin path('<int:pk>/update/', views.updateRegister, name='update'),

It has to be something with my primary key?

gaunt marlin Oct 26, 2020, 3:55 AM

#

@plucky tapir can you show the full error?

#

is Userinfo a context variable you passed to the template?

plucky tapir Oct 26, 2020, 4:01 AM

#

@gaunt marlin https://dpaste.org/DhTH Userinfo is my model's name

gaunt marlin Oct 26, 2020, 4:06 AM

#

@plucky tapir here is the problem
with arguments '('',)' not found

your Userinfo.id return a tuple with a blank string element inside of it

#

check why it return that instead of an integer

plucky tapir Oct 26, 2020, 4:14 AM

#

would Userinfo.id be the way to pass the pk? @gaunt marlin

gaunt marlin Oct 26, 2020, 4:16 AM

#

@plucky tapir you pass your model query as variables to the template right?

#

have you tried to see {{ Userinfo.fname }} show up in your template?

#

yourview(request):
  ...
  query = YouModelName.query_stuffs
  return render('template_path.html', {
     'a_variable': query
})

#

this is an example

#

so i can use {{ a_variable.model_attribute ]} on template to render

plucky tapir Oct 26, 2020, 4:19 AM

#

    Userreg = Userinfo.objects.all()

    context = {'users': Userinfo}

    return render(request, 'users/dashboard.html', context) ```

#

@gaunt marlin objects.all() passes it correct?

gaunt marlin Oct 26, 2020, 4:23 AM

#

yes

#

@plucky tapir wait that is wrong

#

you set variable of your query as Userreg

#

and you settings {'users': Userinfo} which is wrong

#

it supposed to be {'users': Userreg}

#

and in your template @plucky tapir

{% for user in users %}
  {{ user.id }}
{% endfor %}

#

you should pass variable instead of model name

plucky tapir Oct 26, 2020, 4:30 AM

#

@gaunt marlin would I need to add anything in the url 'update' button?

gaunt marlin Oct 26, 2020, 4:31 AM

#

@plucky tapir not yet, first you need to fix your view code like i mentioned above

#

you passing the wrong thing to your context variable

#

that why it returned empty tuple

#

here the fix
your view:

 def home(request):
    Userreg = Userinfo.objects.all()

    context = {'users': Userreg}

    return render(request, 'users/dashboard.html', context)

your template(just an example, apply to your template logic):

{% for user in users %}
  {{ user.id }}
{% endfor %}

#

you users = Userinfo.objects.all() when you set from template

plucky tapir Oct 26, 2020, 4:58 AM

#

@gaunt marlin {% block content %}<h5> Hello {{user.username}} {{ user.id }}</h5>

#

I can see the username and user id although I have a model called Userinfo that I cannot really display any information from

gaunt marlin Oct 26, 2020, 5:01 AM

#

@plucky tapir user is an instance of your Userinfo model, you can display any of the Userinfo attributes like normal. What is your goal ? I cannot really display any information from which information you looking for?

plucky tapir Oct 26, 2020, 5:04 AM

#

For now it was first name last name and city from Userinfo, I also have a User model for Users to login with a password, but focusing on Userinfo at the moment, I had a button there for Update but I wasnt passing a pk properly so I removed it

📎 Screen_Shot_2020-10-25_at_10.02.00_PM.png

gaunt marlin Oct 26, 2020, 5:05 AM

#

@plucky tapir now you will be passing like this with different parameter variable

<td><a class="btn btn-sm btn-info" href="{% url 'update' user.id %}">Update</a></td>

#

remember pk in django is also any field that has primary_key=True

nova nacelle Oct 26, 2020, 5:10 AM

#

django, does anyone have experience with no reverse match error? Apparently its due to an html url call

For now it was first name last name and city from Userinfo, I also have a User model for Users to login with a password, but focusing on Userinfo at the moment, I had a button there for Update but I wasnt passing a pk properly so I removed it

def home(request):
    Userreg = Userinfo.objects.all()

#

he was passing the wrong context variable to the template

#

he set users variable to Userinfo which is the model by mistake

#

it suppsoed to be {'users': Userreg}

pn=models.CharField(validators=[RegexValidator("^0?[5-9]{1}\d{9}$")],max_length=15, null=True, blank=True). use this for the phone number.
@gaunt marlin what do you think about this?

gaunt marlin Oct 26, 2020, 5:46 AM

#

i'm no expert in regex but that is not his error which he just posted
Exception Value: Reverse for 'update' with arguments '('',)

#

he was using this <td><a class="btn btn-sm btn-info" href="{% url 'update' Userinfo.id %}">Update</a></td> so you can see the problem

#

Userinfo

Asking about your attempted solution rather than your actual problem.

Often programmers will get distracted with a potential solution they've come up with, and will try asking for help getting it to work. However, it's possible this solution either wouldn't work as they expect, or there's a much better solution instead.

@plucky tapir have you tried my solution ?

plucky tapir Oct 26, 2020, 6:04 AM

#

@gaunt marlin Alright so now its pulling up my user id, when I believe I need to pull up the primary key that is from the "Create" that I just made

#

From here #web-development message create goes to a form to input info, then it takes me back to the 'dashboard'

gaunt marlin Oct 26, 2020, 6:28 AM

#

@plucky tapir can you describe the flow more clearly? i'm having trouble understanding this I need to pull up the primary key that is from the "Create" that I just made

#

so you have dashboard page that list all the user info with a create button and an update button for each user. The create button will redirect to a create form, the update button redirect to the update form

#

is that what you trying to tell me ?

#

when you create an object from create form, you need to redirect to the dashboard page -> which will query the userInfo table again and list all the userInfo old and new

#

so the dashboard will list all users id order in ascended order

Unsure if this is the best place to ask. Currently researching to build a price aggregator for specific products would python be the best option for scraping ecommerce prices and feeding into a database? Any suggestions on front end frameworks would be appreciated.

gaunt marlin Oct 26, 2020, 6:57 AM

#

@native tide for python there are dedicated package for scraping like scrapy and other. For javascript i can only think of https://github.com/puppeteer/puppeteer , but use what you more comfortable and needed

#

for frontend you might encounter javascript generated contents, for those you can use headless browser

native tide Oct 26, 2020, 6:59 AM

#

@gaunt marlin have used scrapy in the past I haven't touched a scraper in a few years so just making sure it's still my best option needs to be highly scalable. Doing the leg work before I search for a developer.

gaunt marlin Oct 26, 2020, 7:00 AM

there alot of tools, but i generally just use python requests and xml to get web content 😄

@gaunt marlin u can be highly naughty at an exceptional speed with requests 😄

native tide Oct 26, 2020, 7:08 AM

#

@gaunt marlin what do you think about single board computers hosting the scrapers and pushing results to web server vs having web server based scrapers??

gaunt marlin Oct 26, 2020, 7:09 AM

#

@native tide i think it's based on your design, of course having a web scraper running in the background is much cheaper than using single board computers. I don't think web scraping would take that much resource if you have the correct flow

#

i'm no dev ops so i have little or no knowledge about VPS or AWS

native tide Oct 26, 2020, 7:10 AM

#

@gaunt marlin I have around 50 odroids n2 sitting in a box and thought I could use them for this project.

gaunt marlin Oct 26, 2020, 7:11 AM

#

i think you can use those if you want, but you have to be the one maintaining the hardware. I generally run scraper on the server then i only need to maintain the software not the hardware itself

#

imagine this: your android die - > server web still alive get no data
vs
the scraper only die when your server hosting the website

#

i made tag for left and right text but when i used width text anyways goes from left

native tide Oct 26, 2020, 10:53 AM

#

yes so re-position your text

#

use the internet to find the css tag for that

nova nacelle Oct 26, 2020, 10:53 AM

#

Use margin-left:65%

#

And width:35%

gaunt marlin Oct 26, 2020, 10:54 AM

#

you can use float: right or float:left in your div css

native tide Oct 26, 2020, 10:54 AM

#

and just center the text.

vivid canopy Oct 26, 2020, 10:54 AM

@nova nacelle thanks

native tide Oct 26, 2020, 10:54 AM

@stable kite which auth method?

@vivid canopy Your welcome.

@native tide session

native tide Oct 26, 2020, 10:55 AM

within the API endpoints?

stable kite Oct 26, 2020, 10:55 AM

@native tide no with ajax

Django not showing a model in admin page

stable kite Oct 26, 2020, 10:57 AM

#

could you upload your code for that?
@native tide for that you should have both frontend & backend on the same sever

native tide Oct 26, 2020, 10:57 AM

#

@primal kernel Have you done makemigrations?

primal kernel Oct 26, 2020, 10:57 AM

#

Yeah I did it

native tide Oct 26, 2020, 10:57 AM

#

and then migrate?

primal kernel Oct 26, 2020, 10:57 AM

#

Ofc

#

And I can see the results in my DB, my only problem is that I can not see it in my admin page

native tide Oct 26, 2020, 10:58 AM

#

@stable kite not really, but if you can upload your code I'll understand what you're talking about. How can you be doing session auth if it's not in the API endpoints 😄

stable kite Oct 26, 2020, 10:59 AM

#

i am using POST ajax Request for that

native tide Oct 26, 2020, 10:59 AM

#

Yea. So you're making a request to your API which handles the session auth?

stable kite Oct 26, 2020, 11:01 AM

@native tide ```py

you need to either add a DNS entry, or setup a redirect

@zealous tusk Do u have featured_products in your context

any advantages?

@native tide yes.

you can see the code above

ig means I guess?

native tide Oct 26, 2020, 2:10 PM

context = {'featured_product': featured_products}

#

shouldn't it be 'featured_products' for the key

clear arch Oct 26, 2020, 2:11 PM

well thx for your suggestion

How to slice items in django ?

native tide Oct 26, 2020, 2:22 PM

#

yes that was right

#

did it solve the issue?

#

if you do {% for product in featured_products %} the context key is "featured_products" but you had "featured_product" which isn't the same

#

and what do you mean by slice

zealous tusk Oct 26, 2020, 2:23 PM

#

@native tide yes

#

slice means how can i display third element of a query set?

devout coral Oct 26, 2020, 2:32 PM

Good Morning, does anyone here have some advice on how I should be handling caching and sessions in production for a Django web app?

native tide Oct 26, 2020, 2:37 PM

#

@zealous tusk do model.objects.get(e.g. username="user").pk

#

and .pk gives you the primary key

#

so then you can find that element

zealous tusk Oct 26, 2020, 2:38 PM

okay thanks man!

@devout coral why

devout coral Oct 26, 2020, 3:31 PM

#

I am trying to set it up and running into issues

vestal hound Oct 26, 2020, 3:32 PM

#

yes

#

what issues?

#

if you have problems just post them

devout coral Oct 26, 2020, 3:33 PM

#

Well the issue is the task just stays pending forever.

vestal hound Oct 26, 2020, 3:33 PM

#

do you have a worker running?

devout coral Oct 26, 2020, 3:33 PM

#

I have redis inside of a docker and it connects to it just fine but it never executes

vestal hound Oct 26, 2020, 3:33 PM

#

sounds like you don't...? that's my initial guess

devout coral Oct 26, 2020, 3:34 PM

#

Alright, worker is what exactly? Redis is the broker right?

vestal hound Oct 26, 2020, 3:34 PM

#

yes

#

no

#

well

#

okay, let's just say yes

#

anyway

#

so there'll be one process that basically keeps track of tasks

#

and assigns them

#

to workers.

#

so it sounds like you only have the Celery server running

#

but not workers

#

so it has nothing to dispatch the work to

devout coral Oct 26, 2020, 3:36 PM

#

Well, I have celery running. And I have redis in a docker running as well. I thought celery received the task from django when I use the .delay() then it gets sent from celery to redis to be executed...

#

Is that not how it works. This is what I understood from the docs.

vestal hound Oct 26, 2020, 3:37 PM

#

yup, basically

#

okay, never mind what I just said

#

do you have the logs

#

from your running process?

devout coral Oct 26, 2020, 3:37 PM

#

Well, I could not find where to get the logs...

vestal hound Oct 26, 2020, 3:37 PM

#

huh.

#

did you ever run celery?

#

like the command

devout coral Oct 26, 2020, 3:38 PM

#

Yes

vestal hound Oct 26, 2020, 3:38 PM

#

yeah, that window should have logs

devout coral Oct 26, 2020, 3:38 PM

#

I did the info for the log to show on the terminal but I could not find a txt or anything with logs if that is what you mean

vestal hound Oct 26, 2020, 3:38 PM

#

oh, nope

#

just like

#

whatever shows on the terminal

devout coral Oct 26, 2020, 3:39 PM

#

Oh yeah, I can re run it one sec

#

Forgot to run my docker... One more sec

@devout coral what are various frameworks/technologies that come in handy while working on your projects in django?

#

i am looking to shift my job so i am trying to gauge some essential skills

devout coral Oct 26, 2020, 4:20 PM

#

Well the good thing about Django is that it is a "Batteries Included" so you only really need django to get a site running.

sterile peak Oct 26, 2020, 4:21 PM

#

oh that's great to know.. so react or any other fancy JS framework is required?

devout coral Oct 26, 2020, 4:21 PM

#

No.

#

I just use JS and JQuery when needed.

sterile peak Oct 26, 2020, 4:22 PM

#

oh that's great.. but how do we make good UI?

devout coral Oct 26, 2020, 4:22 PM

#

Also if you want to make your front end life a lot easier use bootstrap

sterile peak Oct 26, 2020, 4:22 PM

#

i mean clean UI that is pleasnt to look at

devout coral Oct 26, 2020, 4:22 PM

#

Bootstrap is probably your go to at the beggining.

sterile peak Oct 26, 2020, 4:23 PM

#

i have some experience with it, i worked with bootstrap and jquery couple of years ago

clear arch Oct 26, 2020, 4:23 PM

#

bootstrap 4 is great

devout coral Oct 26, 2020, 4:23 PM

#

So if you have some experience with it I would say use it.

sterile peak Oct 26, 2020, 4:23 PM

#

great man, thanks! since how long you've been coding using django ?

devout coral Oct 26, 2020, 4:24 PM

#

At the beginning bootstrap sucks because you are not sure everything it has and the grid system confuses some but once you have some experience you can make the most of it.

#

@sterile peak A little over a year now

clear arch Oct 26, 2020, 4:24 PM

When I started using Bootstrap it took me like half an hour to figure where everything was xD

@devout coral Congrats on that! are you freelancing?

clear arch Oct 26, 2020, 4:26 PM

#

@devout coral can you please explain why we use templates?

#

static ---> dynamic is that it or something else?

devout coral Oct 26, 2020, 4:27 PM

#

@sterile peak I was I no longer do it. Got annoying after a bit.

#

@clear arch The reason we use templates is to make life easier and no need to re write a bunch of stuff. Also helps a lot with dynamic content.

sterile peak Oct 26, 2020, 4:28 PM

#

okay, let me get my hands dirty with django

devout coral Oct 26, 2020, 4:29 PM

#

Templating allows you to have a base file(base.html) which will contain things that every page will share (header, nav bar, footer, etc.) and then in your body you can place a "block". Later when you are ready to make a page you can "extend" from that base file and replace that "block" with the code in the current html file.

#

Other things it allows you to do is add loops and logic right in your html. So for example if you want to display multiple users in one html page but do not know the quantity or who it is. You can simply pass a query set to your template then use a for loop right in your html to make the necessary tag(s) for each of the users.

toxic flame Oct 26, 2020, 4:31 PM

#

Specially with includes on django

#

it saves alot of copy and pasting

sterile peak Oct 26, 2020, 4:32 PM

I heard flask is more lightweight

#

I've been working with django for around 3-4 months now and I can build large scale projects

#

django is easy to learj and understand

devout coral Oct 26, 2020, 4:35 PM

#

The only way flask is lightweight is that it is smaller in size(because Django includes a lot more out of the box). However, for the same size project doing the same things the performance differences are negligible.

I've been working with django for around 3-4 months now and I can build large scale projects
@toxic flame so what else do you use apart from django??

toxic flame Oct 26, 2020, 4:37 PM

#

backend frameworks?

#

i also know php

sterile peak Oct 26, 2020, 4:38 PM

#

@toxic flame for backend and front end.. i would lke to know the things that are absolutely necessary to build large scale projects

devout coral Oct 26, 2020, 4:38 PM

#

@clear arch no real big difference from what i know tbh. Just that DTL is already included in Django.

Hi ! i'm trying to scrapping and i've some sort of "selector" which aren't button but we can click on it, how can i trigger this action ?

toxic flame Oct 26, 2020, 4:38 PM

#

html, css, sass, js, vuejs, django, these are the default I use for a large scale project

sterile peak Oct 26, 2020, 4:38 PM

#

sass? software as a service?

toxic flame Oct 26, 2020, 4:38 PM

no

vuejs? i am new to UI so please bear with me. i hear about react, flutter and angular but not much of vue.. what is your opinion?

toxic flame Oct 26, 2020, 4:41 PM

#

imo vue is easier and flexible than react

#

vue can have scoped / nested css for each element which is very flexible for me

haughty turtle Oct 26, 2020, 4:43 PM

#

VueJS is good, its open source, I would recommend it if you want to learn it personally, but job wise VueJS isnt as popular as React of Angular atm I have heard. So if you are determined to get a job off the bat then go with something like React or Angular, I personally am going with VueJS then will play with Angular or React later on.

sterile peak Oct 26, 2020, 4:44 PM

#

oh alright, so many js frameworks it gets overwhelming very easily

#

currently i am very focused on getting up to speed with django post that i reckon some js framework would be good thing to learn?

haughty turtle Oct 26, 2020, 4:45 PM

#

from django.db import models


class Category(models.Model):
    category_name = models.CharField(max_length=100)
    
class Product(models.Model):
    product_name = models.CharField(max_length=200)
    product_price = models.DecimalField(max_digits=5, decimal_places=2)
    ```
I am creating a Category model in which new categories can be created such as Clothing, Accesories, Textiles etc. I want my Product model to inherect one of the categories created. How would I go about doing this

clear arch Oct 26, 2020, 4:46 PM

#

I am getting an error when I am typing os.path.join(BASE_DIR, 'templates') the error is name os is not defined?

haughty turtle Oct 26, 2020, 4:46 PM

#

did you import os

clear arch Oct 26, 2020, 4:46 PM

#

in the settings?

haughty turtle Oct 26, 2020, 4:47 PM

#

where you have the following code

clear arch Oct 26, 2020, 4:47 PM

#

in the settings.py file

haughty turtle Oct 26, 2020, 4:47 PM

#

then yes import it there

clear arch Oct 26, 2020, 4:47 PM

#

ok does it matter where I import it?

sterile peak Oct 26, 2020, 4:48 PM

#

yes..

clear arch Oct 26, 2020, 4:48 PM

#

nvm got it thx @haughty turtle

devout coral Oct 26, 2020, 4:49 PM

#

@clear arch Not trying to be rude but it does not seem you are too familiar with python. If this is the case I would suggest you learn python basics before diving into django or you will get VERY overwhelmed.

#

@haughty turtle Did you get your model thing figured out or need some help still?

haughty turtle Oct 26, 2020, 4:50 PM

#

yea need some help still

#

Trying to figure out the best way to go forward, I need to have my products specify what categories they are in as I will need to display them per category later on, as also per gender.}

clear arch Oct 26, 2020, 4:53 PM

#

@devout coral I thought os was already imported as I am following a tutorial in that os module was already imported

devout coral Oct 26, 2020, 4:53 PM

#

@haughty turtle Ok, and your category is a whole model correct?

#

@clear arch Yes it is in there by default.

clear arch Oct 26, 2020, 4:54 PM

#

for mine it was not xD

devout coral Oct 26, 2020, 4:54 PM

#

Uhh, what version of Django do you have?

#

That is very strange.

clear arch Oct 26, 2020, 4:54 PM

#

latest

devout coral Oct 26, 2020, 4:54 PM

#

Ok weird.

haughty turtle Oct 26, 2020, 4:55 PM

#

@devout coral yeah I imagine this would be the best way in Django, will it not? Allowing me to add new categories later on?

#

In terms of user friendliness new categories could just be added in the admin panel

plucky tapir Oct 26, 2020, 4:56 PM

#

Please select a fix:
 1) Provide a one-off default now (will be set on all existing rows with a null value for this column)
 2) Quit, and let me add a default in models.py
``` I'm trying to add an author to a models, do I just add default=True into its definition?

devout coral Oct 26, 2020, 4:58 PM

@haughty turtle Yeah that works. What I would suggest is to make a relationship between categories and product.

#

@haughty turtle Lol... I do not need to read it I know how to do it. I was saying it for your question.

#

Plus I have probably read that a few times already..

toxic flame Oct 26, 2020, 5:04 PM

#

html and css is probably the easiest

haughty turtle Oct 26, 2020, 5:05 PM

#

Yeah, thats what I am reading right now, I completed the Django tut, but that was like 4 weeks agos

#

have been completing the HTML and CSS got that done, now have to refresh what I learnt

devout coral Oct 26, 2020, 5:05 PM

#

If you are starting out with django my suggestion is to always focus on the django part of it instead of front end. Once you have your funcitonality then do the front end.

toxic flame Oct 26, 2020, 5:05 PM

#

you need the basic python knowledge too for django

haughty turtle Oct 26, 2020, 5:05 PM

#

Ah, I did it backwards

devout coral Oct 26, 2020, 5:05 PM

#

@haughty turtle Ok, well for your issue a OneToMany relationship is probably what you are looking for.

#

you need the basic python knowledge too for django
@toxic flame I cannot stress this enough. Seems like a lot of people just want to jump right into django but that is such a big mistake. You will run into all types of issues.

toxic flame Oct 26, 2020, 5:07 PM

#

ForeignKey(Category, on_delete=models.CASCADE) is what u need @haughty turtle

#

put it on the product models

#

cateogroy = models.F....

#

then you can assign a category to a product, which can be filtered by:

#

Product.objects.filter(category__category_name="nameofyourcategiry")

#

I'm on my phone hehee

#

Did not see your answer. Thank you

toxic flame Oct 26, 2020, 5:10 PM

#

It's okay

#

There are alot of ways on making relations but I like this method more

#

it's easier than the OneToManyFields since you have to drag and drop, and do all sort of things before actually linking them together

Celery seems to be a realtime processor for python stuff

devout coral Oct 26, 2020, 5:24 PM

Well it it for asynchronous work, and my set up gives no errors which is even more frustrating. Just sits on pending and never finishes the task.

limber laurel Oct 26, 2020, 5:30 PM

#

@devout coral Could I create a template folder but for the whole project?

devout coral Oct 26, 2020, 5:31 PM

#

@limber laurel Yes, this is normally where you would put your error templates and admin templates to re write the django back end look.

limber laurel Oct 26, 2020, 5:32 PM

#

Ok

devout coral Oct 26, 2020, 5:33 PM

#

However, for the individual app templates you would normally have your templates in there.

pulsar hinge Oct 26, 2020, 6:09 PM

Hi, I'm getting error with js this time.

    at register
    at HTMLSpanElement.onclick```

I have 
```{% extends 'base.html' %}```
 at my account.html(site with problem). I included scripts.html and linked main.js before in base.html. This script is the only one not working: 
```/* Toggle Form */
    var LoginForm = document.getElementById("LoginForm");
    var RegForm = document.getElementById("RegForm");
    var Indicator = document.getElementById("Indicator");

    function register(){
        RegForm.style.transform = "translateX(0px)";
        LoginForm.style.transform = "translateX(0px)";
        Indicator.style.transform = "translateX(134px)";
    }
    function login(){
        RegForm.style.transform = "translateX(-400px)";
        LoginForm.style.transform = "translateX(390px)";
        Indicator.style.transform = "translateX(15px)";
    }```
 
Although when I just copy this script into account.html irt magically works. But that's not how it is supposed to work. It should work by including scripts in base.html. When going into Dev mode at site, my scripts are loading, but they aren't working. I've done everything with staticfiles.

devout coral Oct 26, 2020, 6:10 PM

@pulsar hinge seems like those two elements do not exist.

I'm making a request to my API endpoint to sign users up and I just tried to add session authentication, but I don't know what to do and the DRF docs are confusing.

My error:
{"detail":"Authentication credentials were not provided."}

My view:

@api_view(["POST"])  # API view for POST requests
@permission_classes([IsAuthenticated])
def register(request):  # This will register a user from their POST request.

    if request.method == "POST":
        if "username" and "email" and "password" and "confirm_password" in request.data:

            if request.data["confirm_password"] == request.data["password"]:  # Checks that password is confirmed.
                hashed_password = make_password(str(request.data["password"]))  # Hashes password
                request.data["password"] = hashed_password
            else:
                return Response(data={"password": "Passwords do not match"}, status=status.HTTP_400_BAD_REQUEST)

            serializer = UserSerializer(data=request.data)

            if serializer.is_valid():
                serializer.save()
                return Response(data=serializer.data, status=status.HTTP_201_CREATED)

            else:
                return Response(data=serializer.errors, status=status.HTTP_400_BAD_REQUEST)

        else:
            return Response(data={"error": "Model fields not satisfied"}, status=status.HTTP_400_BAD_REQUEST)```

How do I provide auth details?

print your query

lookup how to mogrify and print the content of your sql query

object of type none has no len

type none

#

check to see if your script is even querying properly

that is my guess

@devout coral so what would I do? I just want to create a new model.

would I allow it to be null?

@mortal mango If the picture is not needed sure, otherwise set a default. Like if it is for a profile picture I would suggest you set a default.

I want to put an image url so I set it as charfield.

so what is the default?

what would it be used for?

Ah Django is so beautiful, my model relationships worked perfectly, was worried about how I would be able to identify which one I would want, but Django made sure to take care of that for me.

#

@mortal mango Show a snippet of the code you are trying to add into models

devout coral Oct 26, 2020, 9:10 PM

@mortal mango You can set the default to just an empty string then.

@haughty turtle Good to hear!

I thought you were using a FileField but since it is just a CharField empty string for default is fine.

What do you mean?

#

You mean the form is not validating and it is giving you that error? Or you cannot migrate?

#

@toxic flame I am not.

Anyone knows how to display a foreign key's attribute instead of its default representation? For example, display the sender's username instead of their primary key

📎 unknown.png

#

Here's my model for the Message object:

#

class Message(models.Model):
    sender = models.ForeignKey(Account, on_delete=models.CASCADE, null=False,
                               blank=False, verbose_name="Sender", related_name='sender')
    receiver = models.ForeignKey(Account, on_delete=models.CASCADE, null=False,
                                 blank=False, verbose_name="Receiver", related_name='receiver')
    content = models.TextField(max_length=512, blank=False, null=False,
                               unique=False, editable=False, verbose_name="Message")
    read = models.BooleanField(default=False)
    timestamp = models.DateTimeField(auto_now_add=True)```

#

class Account(AbstractBaseUser):
    email = models.EmailField(verbose_name="Email", max_length=64, unique=True)
    username = models.CharField(max_length=30, unique=True)
    date_joined = models.DateTimeField(
        verbose_name='Date Joined', auto_now_add=True)
    last_login = models.DateTimeField(verbose_name="Last Login", auto_now=True)
    is_admin = models.BooleanField(default=False)
    is_active = models.BooleanField(default=True)
    is_staff = models.BooleanField(default=False)
    is_superuser = models.BooleanField(default=False)

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['username']

    objects = PigeonAccountManager()

    def __str__(self):
        return self.username

    def has_perm(self, perm, obj=None):
        return self.is_admin

    def has_module_perms(self, app_label):
        return True

    def get_username(self):
        return self.username```

#

That's my model for my account object

devout coral Oct 26, 2020, 9:28 PM

#

@icy fog You mean you want to change it's default representation, like if you were to do a print(object_here)

icy fog Oct 26, 2020, 9:28 PM

#

Yeah, something like that

#

cuz it's not helpful to debug when it's only showing me the ID of the Account object instead of its username

devout coral Oct 26, 2020, 9:28 PM

#

Your __str__ method handles that. So change the return of it

icy fog Oct 26, 2020, 9:29 PM

#

The str method works fine for other representation because it works here where it actually displays the username of the Account object

📎 unknown.png

#

My problem is that it doesn't display the username on the 'sender' attribute when it's represented on the API view of DRF

trim star Oct 26, 2020, 9:31 PM

#

Is it a good practice to have your migration files in your version control repo? It seems not

icy fog Oct 26, 2020, 9:31 PM

#

is there some way to manually change the representation of that without affecting the value of the attribute itself?

devout coral Oct 26, 2020, 9:34 PM

#

@trim star Yeah not a good idea, you normally want to add migrations to gitignore

#

@icy fog What representation, I am sort of confused now.

icy fog Oct 26, 2020, 9:35 PM

#

This representation

📎 unknown.png

trim star Oct 26, 2020, 9:35 PM

#

@devout coral Thats what I thought

icy fog Oct 26, 2020, 9:36 PM

#

It seems to retrieve the Account object's ID and display it directly instead of using the str method of the Account object

#

I don't know if it's possible to change the way DRF API-view displays it

devout coral Oct 26, 2020, 9:36 PM

#

@icy fog Can you not just change it in the view where you do the return for the get request??

icy fog Oct 26, 2020, 9:37 PM

#

Hmm, I think it might be possible but I'm using generics for that one

#

here's what my view for it is:

class MessageListView(ListCreateAPIView):
    queryset = Message.objects.all()
    serializer_class = MessageSerializer
    permission_classes = [permissions.IsAuthenticated]```

#

I don't know if it's possible to define a method which alters the presentation of the Account object's value so that it uses the str method

mortal mango Oct 26, 2020, 9:39 PM

@devout coral

📎 errorrrrrr.JPG

#

that's what pops up when I just click enter to leave a blank string

devout coral Oct 26, 2020, 9:41 PM

#

@icy fog I think a custom serializer is the only way to go then..

#

@mortal mango ... I meant to set a default in your model... Not just press 1 and give it a one off.

mortal mango Oct 26, 2020, 9:42 PM

#

oh

devout coral Oct 26, 2020, 9:42 PM

default=''

mortal mango Oct 26, 2020, 9:42 PM

oh ok

#

it worked!

#

is there a way to upload an image to my domain url? like mydomain.com/image and it would show the image

devout coral Oct 26, 2020, 9:56 PM

#

Like an image field?

mortal mango Oct 26, 2020, 9:57 PM

#

no like I want my domain to be an image url

#

so like I would do mydomain.com/image and it would show the image

#

Like an image field?
@devout coral is there an option for an image field?

devout coral Oct 26, 2020, 9:58 PM

#

Yes image fields exists in django models

mortal mango Oct 26, 2020, 9:59 PM

#

oh so I just want my logo to show up. So people can get the logo.

#

so the easy way would be to do an image field right?

trim star Oct 26, 2020, 10:09 PM

#

I have another best practices question:
So the application that I'm contributing to has a non-interactive mode for instances in which the admin does not have access to the command line. They print an initial default password to stdout for the admin to log in, and never enforce that the admin change that default password.

This seems like a security issue to me..what do you think?

vale orbit Oct 26, 2020, 11:15 PM

#

So would one recommend flask more for api development and django for progressive web apps? Or would it work better to use a flask backend to a react/angular app?

vestal hound Oct 26, 2020, 11:34 PM

#

So would one recommend flask more for api development and django for progressive web apps? Or would it work better to use a flask backend to a react/angular app?
@vale orbit what do you mean "progressive web app"?

#

you can use DRF (Django REST Framework) to build an API

#

consider also FastAPI

vale orbit Oct 26, 2020, 11:44 PM

#

Single Page Application is what I mean.

I have also heard good things about connexion for api development, any thoughts on that one?

vestal hound Oct 26, 2020, 11:46 PM

#

@vale orbit if anything, vanilla Django would be worse than Flask for SPAs

#

never heard of that, sorry

vale orbit Oct 26, 2020, 11:47 PM

#

Ok, then I guess I will stick to my initial instinct of “use flask backend as a replacement for express js”

vestal hound Oct 26, 2020, 11:47 PM

#

DRF will work for that too

Which one allows for faster development time?

native tide Oct 27, 2020, 12:05 AM

#

I'm making a request to my API endpoint to sign users up and I just tried to add session authentication, but I don't know what to do and the DRF docs are confusing.

My error:
{"detail":"Authentication credentials were not provided."}

My view:

@api_view(["POST"])  # API view for POST requests
@permission_classes([IsAuthenticated])
def register(request):  # This will register a user from their POST request.

    if request.method == "POST":
        if "username" and "email" and "password" and "confirm_password" in request.data:

            if request.data["confirm_password"] == request.data["password"]:  # Checks that password is confirmed.
                hashed_password = make_password(str(request.data["password"]))  # Hashes password
                request.data["password"] = hashed_password
            else:
                return Response(data={"password": "Passwords do not match"}, status=status.HTTP_400_BAD_REQUEST)

            serializer = UserSerializer(data=request.data)

            if serializer.is_valid():
                serializer.save()
                return Response(data=serializer.data, status=status.HTTP_201_CREATED)

            else:
                return Response(data=serializer.errors, status=status.HTTP_400_BAD_REQUEST)

        else:
            return Response(data={"error": "Model fields not satisfied"}, status=status.HTTP_400_BAD_REQUEST)```

How do I provide auth details?

vestal hound Oct 27, 2020, 12:05 AM

#

same error
@mortal mango what are you passing in the request

#

@native tide hm.

#

you should let your serializer do all of that

native tide Oct 27, 2020, 12:06 AM

#

what should it do? 😳

vestal hound Oct 27, 2020, 12:08 AM

#

the view?

#

the view should pass the data to the serializer

#

and let it do validation.

#

in particular

#

if you use, for example, is.valid(raise_exception=True)

#

a ValidationError will automatically be caught and returned in the Response as 400

mortal mango Oct 27, 2020, 12:10 AM

#

I give up

#

this is hard

vestal hound Oct 27, 2020, 12:11 AM

#

basically, any work involving converting from/to data that will be sent over HTTP should be done by the serializer

native tide Oct 27, 2020, 12:11 AM

#

Sure I can move over the validation to the serializers, but what do I need to counter:
{"detail":"Authentication credentials were not provided."}
It only appeared as soon as I added session auth. I think I need to provide a CSRF header in my request but I did that (I think) and I'm not getting anywhere

#

@mortal mango in your Response, do data={your dict}

vestal hound Oct 27, 2020, 12:13 AM

#

that's probably a frontend problem

native tide Oct 27, 2020, 12:14 AM

#

Probably, I just don't know what it wants as "Authentication credentials"

#

Ah, actually I think I see what I may have done wrong

#

For session auth I think I need to include the user's username and password in the request

#

of a user that already exists

vestal hound Oct 27, 2020, 12:19 AM

#

yeah, I'd guess that you're sending your auth stuff wrong

mortal mango Oct 27, 2020, 12:23 AM

#

@mortal mango in your Response, do data={your dict}
@native tide is response in my views or in my actual post request?

native tide Oct 27, 2020, 12:23 AM

#

#settings.py
REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': [
        'rest_framework.authentication.SessionAuthentication',
        'rest_framework.authentication.BasicAuthentication'
    ],

    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.IsAuthenticated',
    ]
}```

It's so weird. As soon as a enable SessionAuth I get that error, even on the signup view. So I must be doing something wrong

#

@mortal mango Your POST request is a request to the server. The response is the server's JSON response, which is in your view.

#

I heard that using token auth is bad, is that true? I got discouraged from using it in favor of sessions - but that's a headache.

vestal hound Oct 27, 2020, 12:47 AM

#

I heard that using token auth is bad, is that true? I got discouraged from using it in favor of sessions - but that's a headache.
@native tide why is it bad?

native tide Oct 27, 2020, 12:47 AM

#

I don't know, I just got told session auth > token auth

#

and now that I'm reading about it, for my specific use case making AJAX requests to my api, I think that token auth is more suited

vestal hound Oct 27, 2020, 1:26 AM

#

huh.

#

any justification?

#

if not I wouldn't be too fixated on that

native tide Oct 27, 2020, 1:29 AM

#

just because I don't want to fiddle around with cors and cookies 😄

vestal hound Oct 27, 2020, 1:29 AM

#

no, I mean, why session auth > token auth

native tide Oct 27, 2020, 1:30 AM

#

I wouldn't know. I just got told it is, infact it was in this channel lmao

vestal hound Oct 27, 2020, 1:38 AM

#

huh.

#

if you can find the message it might be easier

gaunt marlin Oct 27, 2020, 2:06 AM

#

@native tide if you using session authentication then you need to pass csrf token in your POST request, how are you passing it on the frontend?

#

ajax ? or just normal form

native tide Oct 27, 2020, 2:16 AM

#

Was doing it with a normal form, I had the header with the X-CSRFToken but I was getting an error (its somewhere up in the chat).

I'm going to stick with tokens though.

gaunt marlin Oct 27, 2020, 2:31 AM

#

@native tide that not really answer my question. There 2 way to send a POST request from the front end. Use normal form with {% csrf_token %} in the form. But you said had the header with the X-CSRFToken which is the method of using ajax/jquery to send POST request

toxic flame Oct 27, 2020, 2:33 AM

Discord has support for Markdown, which allows you to post code with full syntax highlighting. Please use these whenever you paste code, as this helps improve the legibility and makes it easier for us to help you.

To do this, use the following method:

```python
print('Hello world!')
```

Note:
• These are backticks, not quotes. Backticks can usually be found on the tilde key.
• You can also use py as the language instead of python
• The language must be on the first line next to the backticks with no space between them

This will result in the following:

print('Hello world!')

Is there an easy way to reuse a navbar?

gaunt marlin Oct 27, 2020, 9:10 AM

#

@gentle ingot yes if you talking about code base then you can apply that navbar in a block and reuse that block in other templates.

gentle ingot Oct 27, 2020, 9:10 AM

#

Okay thanks. Ill look into blocks. I only have three pages and it's already getting annoying updating the links lol.

@gaunt marlin I'm not using Django forms. I'm using a React frontend, with the csrf token in the header. But idk lol

gaunt marlin Oct 27, 2020, 10:09 AM

#

@native tide for react you need to set header in your POST request

headers: {"X-CSRFToken": csrfToken}

#

your csrfToken you get from Django

#

if you using react then why not use JWT token instead?

#

session way harder to manager with a front end framework

native tide Oct 27, 2020, 10:11 AM

#

Yea I'm using token auth, well im trying to

#

Apparently my models need to extend the base User model which Django provides

#

So now I'm changing it all :D

gaunt marlin Oct 27, 2020, 10:12 AM

#

that sound like reinventing the wheel for me

native tide Oct 27, 2020, 10:12 AM

#

Lmao it feels like it too

#

Been stuck on auth for 3 days, but it is what it is

Is there anyway to do password hashing within a Django model, instead of doing it outside the model then passing the hashed password to the model?

gaunt marlin Oct 27, 2020, 10:51 AM

#

you can override save() method of your model to do hashing within model when call save() outside

native tide Oct 27, 2020, 10:54 AM

#

sounds good, thanks!

#

also what is your unsatisfied with the return string?
@gaunt marlin I don't want it to return in list format tho.

gaunt marlin Oct 27, 2020, 10:57 AM

#

@merry copper from your image seem like image_path data return a list of many image path, you can do a for loop on image_path and just return each one

#

for example

image_path_list = []
for path in image_path:
  image_path_list.append(site_url + path)

return {'image_path': image_path_list}

#

does this make sense ?

gentle ingot Oct 27, 2020, 11:03 AM

#

@gentle ingot yes if you talking about code base then you can apply that navbar in a block and reuse that block in other templates.
@gaunt marlin I didn't think about this earlier but can I update the active tab?

gaunt marlin Oct 27, 2020, 11:03 AM

#

@gentle ingot what do you mean ?

#

active tab ?

When you switch from home to games>brotastic, look at the change in highlight on the navbar.

Hi. I have a serializer which is based on a model with a relationship to another model. Relationship is called staff and it has blank=True and null=True. However, when i ask my serializer to validate some dict-like data with a missing staff field, it invalidates and says: "This field is required.". Ok - fine...So to counter that i then setup in my serializer staff = serializers.PrimaryKeyRelatedField(queryset=Staff.objects.all(),required=False) and now i don't get the required error anymore... But heck, if i then now use my serializer to serialize an existing object, I now then get this error: "AttributeError: 'RelatedManager' object has no attribute 'pk'"... So what do I do? How do i use serializers on models with non-mandatory relationships?

#

@gaunt marlin session way harder to manager with a front end framework no its not. And sessions are safer

#

JWT is mainly for public APIs and JWT's are heavily overused and misunderstood. Just dont use them

#

further they require you to maintain whitelists/blacklists, frequent and infrequent refreshing etc..... loads of annoyances... Session cookies has been around for a long time and have proven their worth. They are httponly (as opposed to e.g. JWT which can be read easily from JS)...and they are nativly supported in most webframeworks

native tide Oct 27, 2020, 11:18 AM

#

you can store a jwt in a cookie

#

a lot of people would recommend you do

silver shell Oct 27, 2020, 11:19 AM

#

@native tide sure you can...but you cannot store it in an http only cookie

#

for obvious reasons

native tide Oct 27, 2020, 11:19 AM

#

sure you can?

silver shell Oct 27, 2020, 11:20 AM

#

ok, how on earth would you do that?

native tide Oct 27, 2020, 11:20 AM

#

nah bruh session auth is harder to do if you have a react frontend at least

#

compared to token

#

im not about to argue best practice and if you should or shouldnt

#

im simply saying you can and it eliminates the js can access it thing

How to store a JWT token inside an HTTP only cookie?

I have created an app that simply uses a JWT sent by the server upon correct login credentials, and authorizes against any /api route on my backend Express.js server.

AngularJS, on the other hand...

#

@native tide eh no...got my session based cookie stuff going w. react frontend in 1 hour or so

native tide Oct 27, 2020, 11:21 AM

#

good for you

silver shell Oct 27, 2020, 11:22 AM

@native tide further...why would you even do that if thats what sessions are already doing?
