### create.htmlの作成

/hello/views.py
from django.shortcuts import render
from django.http import HttpResponse
from django.shortcuts import redirect
from .models import Friend
from .forms import HelloForm
def index(request):
data = Friend.objects.all()
params = {
'title': 'Hello',
'data': data,
}
return render(request, 'hello/index.html', params)
# create model
def create(request):
params = {
'title': 'Hello',
'form': HelloForm(),
}
if(request.method == 'POST'):
name = request.POST['name']
mail = request.POST['mail']
gender = 'gender' in request.POST
age = int(request.POST['age'])
birth = request.POST['birthday']
friend = Friend(name=name, mail=mail, gender=gender, age=age, birthday=birth)
friend.save()
return redirect(to='/hello')
return render(request, 'hello/create.html', params)
– models.pyで定義しているFriendインスタンスを作成して、インスタンスを保存する
– return redirectでリダイレクト
/hello/urls.py
from django.urls import path
from . import views
urlpatterns = [
path('', views.index, name='index'),
path('create', views.create, name='create'),
]
流れとしては、create.htmlからcreate.htmlにpostして、modelのインスタンスを使ってsave()してリダイレクトさせる
リダイレクト先で、if request.method == ‘POST’としても同じだろう。
