The easiest way to get started with Django

Get started with Django

I've only touched bottles until now, but I'm thinking of working on Django and just building the environment for the time being. I've been using Python 2 for a long time, so I've stumbled upon the introduction of the latest version of Django, so I'll summarize it.

Please install Python3 for the time being.

Building a virtual environment

I thought it would be a hassle to create a virtual environment, but I realized that it would be more troublesome not to create a virtual environment. We recommend that you create a virtual environment with Sokko. It is a waste of about 6 hours to do it without creating a virtual environment.

Create a folder with the name Djangoproject. We will build an environment here.

$ sudo pip install virtualenv
$ sudo pip install virtualenvwrapper

Let's move to the Djangoproject directory and build it.

$ cd Djangoproject
$ virtualenv --python="`which python3.5`" virtualenv

Enable the virtual environment.

$ source virtualenv/bin/activate

Success if it starts with (virtualenv) ~.

Install Django and do the initial setup

Install Django with the virtual environment enabled in the Djangoproject directory.

$ sudo pip install django

Check with pip freeze to see if it works. Maybe Django 1.10 ~ is included.

Create a project.

$ django-admin startproject mysite

The old Django was django-admin.py, so the command has changed.

mysite/   manage.py   mysite/    init.py    settings.py    urls.py    wsgi.py

If it looks like the above, you are successful. Next, let's create an application.

$ cd mysite
$ python manage.py startapp myapp

myapp/   init.py   admin.py   apps.py   migrations/      init.py   models.py   tests.py   views.py

It is OK if it has the above configuration.

After that, we will set it according to the tutorial.

myapp/views.py



from django.http import HttpResponse

def index(request):
    return HttpResponse("Hello, world.")

Be careful here. Create a urls.py in myapp /.

myapp/urls.py


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

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

mysite/urls.py


from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url(r'^myapp/', include('myapp.urls')),
    url(r'^admin/', admin.site.urls),
]

mysite/settings.py


INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'myapp', #Add this wording
]

If you can do this, the initial settings are complete. Return to mysite directory

$ python manage.py runserver

http://localhost:8000/myapp/

You should be able to check at.

Now that you've done that, let's display the template in Django. http://qiita.com/Gen6/items/a5562c36fc5c67c89916

Roughly, I summarized it in a book. https://www.amazon.co.jp/dp/B071S25M33
