Hi guys. I'm trying to take a ShoppingCart with many ShoppingCartItems and have a form on the page that iterates through and shows all ShoppingCartItems, and allows you to update their quantities. Django documentation on Forms seems to show a lot of static examples, but what about this example when ShoppingCartItems is very dynamic?

I take that back. I do NOT have a model of "ShoppingCart," only ShoppingCartItem that has the user as their FK. Does it make better sense to create one even though it's to keep track of the items in the cart?

I feel like I'm missing something very simple here, as this use case can be used with almost any CRUD app with relationships that I've ever dreamed up

scrapcode: You'd want a formset for this - multiple "forms" each representing an item of the same type (a ShoppingCartItem, probably), which in turn have a reference to the product and the count.

Then you might need some JS to make the in-page stuff dynamic.

I don't know why I was thinking so hard into it. I know I've read the FormSet docs and ModelFormSet docs. But yeah, that's exactly what I'm looking for.

Thank you.

schinckel, with drf how can i authenticate someone coming from a different server?

I have no idea: never used DRF.

FunkyBob, ^ ?

logically: read the drf docs on auth

you have multiple options

jessamynsmith, these seem to be limited to same-server implementations

logically: What gives you that impression? Requests with auth tokens, for example, can have any source.

logically - you need to use an auth token

That is why that technology exists

You'll also need to set up some sort of CORS policy

mcspud, how do i set up the cors policy

I use django-cors-headers for django, and implement it using the AWS CORS configuration on the servers

I use the same

well, sorry, I use django-cors-headers and heroku

mcspud, jessamynsmith why do i have to create a token for every user as it says?

logically what do you mean? Every unique user needs a unique way to identify them

mcspud, but users wont be making the api requests

Who will then?

mcspud, oh

logically - even if you only have a system-to-system type interaction, don't conflate the term "user" with "human". Anything - man or machine - that uses your system is a "USEr"

mcspud, right

mcspud, what do you mean you implement django-cors-headers usisng AWS CORS config?

Django doesn't allow CORS by default, so you need to modify it so it does. Also, AWS doesn't allow it by default either, so you also need to modify AWS to allow it

logically: what will be making api requests?

jessamynsmith, my bot hosted on a digitalocean droplet

mcspud, but i wont be using aws

logically: so you won't even need cors

cors allows other web apps access

logically: my advice: enable token auth, make a user for your bot and give it a token, then try connecting from the bot

jessamynsmith, thanks

jessamynsmith, what's this about needing https? Is it really needed right now? what if i just want to test in production?

it's better to use https but it should work without

jessamynsmith, ok cool B)

urgh

logically - install django_extensions and werkzeug

Then you can automatically generate a self-signed certificate and test on SSL that way

Its much better

it is indeed

how is it better mcspud jessamynsmith ?

Well when you break something, like I do with the CoC (thanks sasha` !), it will keep a handle of every frame in the stack and give you a web-browser based interactive debugger.

What that means in non-technical jargon is it you can directly interact with every part of your computation that caused on error

It also means that your settings for things like SECURE_COOKIES AND SECURE_CSRF are much more consistent between development and production

so i have a template i want to include in my django 2.0 but is not loading

{% include "foo/bar.html" %}

try ./foo/bar.html

nope not working

theWhisper_: (1) Where is the template folder in your file structure ? (2) Did you point django to your template folder in settings?

yes

but i have several template folders

What's your structure like? A template folder in each app?

yes

correct

Share the path of the tempplate file you're trying to load. Did you remember to namespace the folder?
