Hello everyone! How can I use jinja tags in django forms? I tried this: https://pastebin.com/g8ZGUJ82 But its not working

I don't think you can use Jinja in forms.py, only in html files!

Rebellion

Just copy from here. Most of the things are converted in gitignore

Rebellion

it's just not working just showing me the tag I wrote. It should get data from the backend. {{ product.profit }} needs to display integer but its just not working. No errors

Just check if you are passing 'product' object through context data from backend. If yes, then check if 'product' object having 'profit' attribute. If both conditions are satisfied then it will print {{product.profit}} value in template.

Hey everyone! I have an working sqlite db, and want to make web-based app to fill that web with forms, reports etc. Also i want to change db to postgresql. Which option is more right: 1) create pg db with pgadmin or something and after that include it in django project 2) create django project and create new db right in project First option is simpler for me, because I’m not familiar with django, but may be second one more correct, idk Sorry, if this question may be stupid, i’ve never worked with django Thank you P.s also links to right django-developing patterns and best practicies will be really appreciated:)

Hi, if you have an existing database, read this first: https://docs.djangoproject.com/en/4.1/howto/legacy-databases/

Jor

once completed, and fully functional, run dumpdata into a json, then, create a clean postgresdb, and change the django settings to point into that db, and then import your json follow this: https://medium.com/djangotube/django-sqlite-to-postgresql-database-migration-e3c1f76711e1

Jor

it will be frustrating for sure

Hi guys, I'm know the basics of python. To day I finished studying OOP. Is it time to learn Django???

learn django while you learn python, we use lot of stuff we don't even understand, but it works, everyday you will be like "ooooohhh, thats why", it's like maths, you don't understand why b2 +- ,|4ab / 2a works, but you use it a lot... and then with years you find the demonstration and it's a big wow

Jor

Hello There, I am a reactJS developer and python was my first choice. Now I wanna learn python because it has larger career opportunities. Should I start with django?. Please suggest a roadmap. Appreciated. Should I consider learning python DSA?

keep with React, i'm full python and noone cares, React everywhere

S

keep with React, i'm full python and noone cares, React everywhere

Where you from? Just curious where python is not useful.

Jor

Kindly can someone explain to me the concept of signals and decorators in Django please 🥺🥺

decorators are functions wrappers, it's add functionality to your existing functions without changing them. Signals are like triggers, when some instance calls a save method or a delete, then it triggers your signal function. per example: everytime a user change his data, a mail will be sent. (this is not async), if your mail last forever your user may not be able to finally change the data)

Jor

for async use Celery

So you worked in React also?

Jor

nope

Jor

i work with python, but not in the industry, i work at the Prosecutor's office

Jor

Good point...👍🏾

also, signals can be triggered before or after the method you are calling

Jor

pre-delete pre-save

How to make a drop-down dynamic form field.or how to connect a form choice to a database coloumn.

you can do a lot of stuff with the Form Class, I use CrispyForm which comes with Select2 integrated. For dynamic options you should change your def init and change your myfield.queryset = Model.objects.filter(blabla)

Jor

you can even pass parameters to your FormClass from your views to the init

Jor

with kwargs

S

you can even pass parameters to your FormClass from your views to the init

Hi! http://localhost:8000/i18n/setlang/ 404 Page not found Error. Any idea? thanks!

Please provide a full explanation including all the details that you consider relevant. Your statement is too broad and there is no clear way to answer you, you have to explain: - what you're doing - what you're expecting - what you're using - where you're running the script - what Python version you're using - what packages and their versions you're using - and the most important thing: show the code YOU wrote (read rule 5️⃣ for that) and more details, that way your chances to get help will increase

Does viewsets/routers automatically add endpoints for create/delete? I only want read-only API.

Does viewsets/routers automatically add endpoints for create/delete? I only want read-only API.

Default/simple Router only generates endpoint of viewList and ViewDetail And viewset automatically handle the valid methods like get,delete, etc
