}
}

)
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
generatescaffold --model Blog

views
- blogs/views/blog_views.py
変更しないけどコード見てみる。

urls.py
blogs の url を追加。
- ownsomeblog/urls.py
urlpatterns = patterns('', url(r'^', include('blogs.urls')), )
syncdb
$ python manage.py syncdb
generatescaffold --model Post

なかなかよさそうかも。時間空いたら調べてみるかも。
