「Python の Web フレームワーク Django って凄い」ってアピールのに "django-generate-scaffold" を使って3分でブログを作るとよいかもな件

Django Python

DjangoRuby on Rails の scaffold 的なことをする『django-generate-scaffold』を使ってみる。
(Python==2.7, Django==1.4, django-generate-scaffold==0.0.3a1)

Install: django-generate-scaffold

$ pip install django-generate-scaffold

startproject

$ django-admin.py startproject ownsomeblog
$ cd ownsomeblog/
$ python manage.py startapp blogs
$ ls
blogs/
manage.py
ownsomeblog/

settings.py

  • ownsomeblog/settings.py

SQLite3 設定。
INSTALLED_APPS に 'blogs', 'generate_scaffold' を追加。

:
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3', 
        'NAME': 'sqlite3.db',
:
    }
}
:
INSTALLED_APPS = (
:
    'blogs',
    'generate_scaffold',
)

generatescaffold --help

generatescaffold のヘルプを見てみる。

$ python manage.py generatescaffold --help
Usage: manage.py generatescaffold [options] 

Rails-like view/template generator.

manage.py generatescaffold <app_name> [options] <model_name> [field_name:field_type ...]

For example, to generate a scaffold for a model named "Post" in an app named "blogs",
you can issue the following command:

manage.py generatescaffold blogs Post title:char body:text blog:foreignkey=Blog

Options:
  -v VERBOSITY, --verbosity=VERBOSITY
                        Verbosity level; 0=minimal output, 1=normal output,
                        2=verbose output, 3=very verbose output
  --settings=SETTINGS   The Python path to a settings module, e.g.
                        "myproject.settings.main". If this isn't provided, the
                        DJANGO_SETTINGS_MODULE environment variable will be
                        used.
  --pythonpath=PYTHONPATH
                        A directory to add to the Python path, e.g.
                        "/home/djangoprojects/myproject".
  --traceback           Print traceback on exception
  -d, --dry-run         Do not actually do anything, but print what would have
                        happened to the console.
  -m EXISTING_MODEL, --model=EXISTING_MODEL
                        An existing model to generate views/templates for.
  -t TIMESTAMP_FIELDNAME, --timestamp-field=TIMESTAMP_FIELDNAME
                        The name of the field used as a timestamp for date-
                        based views. This option may only be used when passing
                        a model via the `--model` option.
  -n, --no-timestamps   Do not automatically append created_at and updated_at
                        DateTimeFields to generated models.
  --version             show program's version number and exit
  -h, --help            show this help message and exit

urls.py

blogs の url を追加。

urlpatterns = patterns('',
                       url(r'^', include('blogs.urls')),
)

syncdb

$ python manage.py syncdb
