# First Django App
Following [here at djanoproject.com](https://docs.djangoproject.com/en/4.1/intro/tutorial01/)
## Install
In anaconda
```bash
conda install -c anaconda django
```
test: run this in an interactive shell and see if you get an error or not
```python
import django
```
## First app
```bash
django-admin startproject mysite
```
structure:
```
mysite/
    manage.py
    mysite/
        __init__.py
        settings.py
        urls.py
        asgi.py
        wsgi.py
```
```bash
python manage.py runserver
```
By default this uses port `8000`, but we can
```bash
python manage.py runserver 8080
python manage.py runserver 0.0.0.0:8080
```
## Creating the app
```bash
python manage.py startapp polls
```
then in `polls/views.py`
```python
from django.http import HttpResponse

def index(request):
  return HttpResponse("Hello World")
```
and in `pools/urls.py`
```python
from django.urls import path

from . import views

urlpatterns - [
  path('', views.index, name="index")
]
```
then in `mysite/urls.py` (this is the master `urls.py` for the whole project, whereas `polls` is an app that lives within the project.
```
from django.contrib import admin
from django.urls import include, path

urlpatterns = [
  path('polls/', include('polls.urls'))
  path('admin/', admin.site.urls),
]
```
you should *always* use `include()` to include other {URL} patterns,
the exception being `admin.site.urls`
### path()
```python
path(route, view, kwargs, name)
# route -- url pattern
# view -- function to delegate to
# additional kwargs -- for the view function
# name -- give the route a name
```
