View와 URL 연결하기🤪

Views : what information is being shown to the client

URLs : where that information is shown on the website

They work in concert so you can think of each View/URL pairing as a web page on the website.

 

✅How to connect a View to a URL 

➡ path() 함수 사용해서!

매개변수 :

- route : String code the contains the URL pattern.
Django will scan the relevant urlpatterns list until it finds a matching string route

- view : Once a matching route is found, the view argument connects to a function or view, typically defined in the views.py file of the relevant Django app.

- kwargs(optional) : Allows us to pass in keyword arguments as a dictionary to the view.

- name(optiona) : Allows us to name a URL in order to referecne it elsewhere in Django.

 

Code Examples🤪:

my_site 프로젝트 내부의 my_app이란 애플리케이션의 view와 url을 연결하고 프로젝트 레벨 url로 연결하기.

#my_site > my_app > views.py

from django.shortcuts import render
from django.http.response import HttpResponse

# Create your views here.
def simple_view(request):
    return HttpResponse("SIMPLE VIEW"); #TEMPLATE HTML (JINJA)

#my_site > my_app > urls.py

from django.urls import path
from . import views

#domain.com/my_app/
urlpatterns=[
    path('simple_view',views.simple_view),
]

#my_site > my_site  > urls.py

from django.contrib import admin
from django.http import HttpResponse
from django.urls import path,include
from . import views


urlpatterns = [
    path('admin/', admin.site.urls),
    path('my_app/',include('my_app.urls')),
]
