[Django]指定IDのレコードを取得

### 特定のIDのみ取り出す
/hello/forms.py

from django import forms

class HelloForm(forms.Form):
	id = forms.IntegerField(label='ID')

/hello/templates/hello/index.html

<body class="container">
	<h1 class="display-4 text-primary">{{title}}</h1>
	<p class="h5 mt-4">{{message|safe}}</p>
	<form action="{% url 'index' %}" method="post">
		{% csrf_token %}
		{{ form}}
		<input type="submit" value="click">
	</form>
	<hr>
	<table class="table">
		<tr>
			<th>ID</th>
			<th>NAME</th>
			<th>GENDER</th>
			<th>MAIL</th>
			<th>AGE</th>
			<th>BIRTHDAY</th>
		</tr>
	{% for item in data %}
		<tr>
			<td>{{item.id}}</td>
			<td>{{item.name}}</td>
			<td>{% if item.gender == False %} male{% endif%}
				{% if item.gender == True %} female{% endif%}</td>
			<td>{{item.mail}}</td>
			<td>{{item.age}}</td>
			<td>{{item.birthday}}</td>
		</tr>
	{% endfor %}
	</table>
</body>

– Friend.objects.get(id=num)でレコードを一つ取り出す
– Managerクラスが取り出している
/hello/views.py

from django.shortcuts import render
from django.http import HttpResponse
from .models import Friend
from .forms import HelloForm

def index(request):
	params = {
		'title': 'Hello',
		'message': 'all friends.',
		'form': HelloForm(),
		'data': [],
	}
	if(request.method == 'POST'):
		num=request.POST['id']
		item=Friend.objects.get(id=num)
		params['data'] = [item]
		params['form'] = HelloForm(request.POST)
	else:
		params['data'] = Friend.objects.all()
	return render(request, 'hello/index.html', params)

views.pyの関数がMVCのコントローラみたいな役割をしてますね。
