Django 3 Scaffold Package

Build Status Build Status Build Status Build Status Build Status

Overview

imagine that you need to build a customized admin panel from scratch or maybe you need a second panel just for your customers, regular users or something like that , then you need this package to do it very fast.

this package creates models and views and forms and URLs and tests and templates for crud in one single command!

for example, you just run a single command in your command-line like this :

python manage.py scaffold forum --model Forum char:name char:reads

and this package generates these files for you :

└── forum
   ├── __init__.py
   ├── admin.py
   ├── apps.py
   ├── forms.py
   ├── migrations
   │   └── __init__.py
   ├── models.py
   ├── templates
   │   ├── base.html
   │   └── forum
   │       ├── details.html
   │       └── list.html
   ├── tests.py
   ├── urls.py
   └── views.py

Installation

  • Install django3scaffold (ideally in your virtualenv!) using pip or simply getting a copy of the code and putting it in a directory in your codebase.

     pip install django3scaffold
    
  • Add django3scaffold to your Django settings INSTALLED_APPS\ :

    INSTALLED_APPS = [ # ... "django3scaffold", ]

  • Add the following to your settings.py with appropriate values:

    • IS_DEV

    • IS_PROD

    • DOMAIN_NAME

    • WWW_ROOT

      DOMAIN_NAME= 'localhost'
      WWW_ROOT = BASE_DIR
      IS_DEV = True
      IS_PROD = False
      
  • Add django3scaffold to your Django settings TEMPLATE_CONTEXT_PROCESSORS\ :

    'OPTIONS': {
         'context_processors': [
             ...
             'django3scaffold.context_processors.django3scaffold_settings',
             ...
    
         ],
    

usage

#. Run

To run scaffold type:

    python manage.py scaffold APPNAME --model MODELNAME [fields]

APPNAME is app name. If app does not exists it will be created. MODELNAME is model name. Just enter model name that you want to create (for example: Blog, Topic, Post etc). It must be alphanumerical. Only one model per run is allowed!

[fields] - list of the model fields.

#. Field types

Available fields:

    char - CharField
    text - TextField
    int - IntegerFIeld
    decimal -DecimalField
    datetime - DateTimeField
    foreign - ForeignKey

All fields requires name that is provided after : sign, for example:

char:title text:body int:posts datetime:create_date

Two fields foreign and decimal requires additional parameters:

  • "foreign" as third argument takes foreignkey model, example:

    foreign:blog:Blog, foreign:post:Post, foreign:added_by:User

NOTICE: All foreign key models must alread exist in project. User and Group model are imported automatically.

  • decimal field requires two more arguments max_digits and decimal_places\ , example:

    decimal:total_cost:10:2

NOTICE: To all models scaffold automatically adds two fields: update_date and create_date.

#. How it works?

Scaffold creates models, views (CRUD), forms, templates, admin, urls and basic tests (CRUD). Scaffold templates are using two blocks extending from base.html:

    {% extends "base.html" %}
    {% block page-title %} {% endblock %}
    {% block conent %} {% endblock %}

So be sure you have your base.html set up properly.

Scaffolding example usage

Let's create very simple forum app. We need Forum , Topic and Post model.

  • Forum model

Forum model needs just one field name :

    python manage.py scaffold forum --model Forum char:name
  • Topic model

Topics are created by site users so we need: created_by , title and Forum foreign key ( update_date and create_date are always added to models):

    python manage.py scaffold forum --model Topic foreign:created_by:User char:title foreign:forum:Forum
  • Post model

Last one are Posts. Posts are related to Topics. Here we need: title , body , created_by and foreign key to Topic\ :

    python manage.py scaffold forum --model Post char:title text:body foreign:created_by:User foreign:topic:Topic

All data should be in place!

Now you must add forum app to INSTALLED_APPS :

``
INSTALLED_APPS = [
    # ...
    "forum",
]
``

Now you must include app in urls.py file by adding into urlpatterns:

from django.conf.urls import url
from django.urls import include

   urlpatterns = patterns('',

       url(r'', include('forum.urls')),

   )

Now syncdb new app and you are ready to go:: add include and url and path ro url file add app name to settings fix from django.urls import reverse in views

  python manage.py migrate --run-syncdb
  python manage.py makemigrations
  python manage.py migrate

Run your server:

python manage.py runserver

And go to forum main page:

http://localhost:8000/forum/

All structure are in place. Now you can personalize models, templates and urls.

At the end you can test new app by runing test:

python manage.py test forum

Creating test database for alias 'default'... .......

Ran 7 tests in 0.884s

OK

Happy scaffolding!
