[PYTHON] Best practices for Django views.py and urls.py (?)

Before making a simple application with Django

How can I learn around the settings of views.py and urls.py in a very easy way? I thought that if I suppressed only the basics before repeating many mistakes, the rest would be smooth.

The introduction of Django is a past article http://qiita.com/Gen6/items/1848f8b4d938807d082e

It is assumed that the template setup has been completed as this time. http://qiita.com/Gen6/items/a5562c36fc5c67c89916

I think that the story will be easier to understand if you do the same by referring to past articles.

Let's display the time

templates/index.html

{% extends "base.html" %}
{% block body %}

    <p>{{hour}}It's time</p>

{% endblock %}

myapp/urls.py

from django.conf.urls import url
from . import views

urlpatterns = [
    url(r'^$', views.index, name='index'),
    url(r'^template/$', views.index, name='index'),
]

myapp/views.py

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


def index(request):
    Datetime = {
        'hour': datetime.now().hour,
    }
    return render(request, 'index.html', Datetime)

If you check the above at http://127.0.0.1:8000/myapp/, the time should be displayed. If the time zone is out of order, change from'UTC'to'Asia / Tokyo'in settings.py.

Try to make a form that returns the contents after entering the name

templates/index.html

{% extends "base.html" %}
{% block body %}

    <form action="" method="get">
      <label>name:<input type="text" size="20" name="your_name"></label>
      <input type="submit" value="Send">
    </form>
    {% if your_name %}
      <p>{{ your_name }}Hey,.</p>
    {% endif %}

{% endblock %}

myapp/urls.py

from django.conf.urls import url
from . import views

urlpatterns = [
    url(r'^$', views.get_query, name='get_query'),
    url(r'^template/$', views.index, name='index'),
]

myapp/views.py

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


def get_query(request):
    Message = {
        'your_name': request.GET.get('your_name'),
    }
    return render(request, 'index.html', Message)

If you check the above at http://127.0.0.1:8000/myapp/, a form will appear, Returns the string entered in the form.

How to mix the two behaviors

Well, the main subject is from here. How can I make use of the form while displaying the time?

An example that does not work

templates/index.html

{% extends "base.html" %}
{% block body %}

    <p>{{hour}}It's time</p>
    <form action="" method="get">
      <label>name:<input type="text" size="20" name="your_name"></label>
      <input type="submit" value="Send">
    </form>
    {% if your_name %}
      <p>{{ your_name }}Hey,.</p>
    {% endif %}

{% endblock %}

myapp/urls.py

from django.conf.urls import url
from . import views

urlpatterns = [
    url(r'^$', views.index, name='index'),
    url(r'^$', views.get_query, name='get_query'),
    url(r'^template/$', views.index, name='index'),
]

myapp/views.py

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


def index(request):
    Datetime = {
        'hour': datetime.now().hour,
    }
    return render(request, 'index.html', Datetime)

def get_query(request):
    Message = {
        'your_name': request.GET.get('your_name'),
    }
    return render(request, 'index.html', Message)

This will not work. Where is the problem?

Working example

myapp/urls.py

from django.conf.urls import url
from . import views

urlpatterns = [
    url(r'^$', views.index, name='index'),
    url(r'^template/$', views.index, name='index'),
]

myapp/views.py

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


def index(request):
    Message = {
        'your_name': request.GET.get('your_name'),
        'hour': datetime.now().hour
    }
    return render(request, 'index.html', Message)

I think that if you can grasp it, you can deepen your understanding by trying various settings.

The actual application creation is in a separate article. http://qiita.com/Gen6/items/735245423b65698428be
