Django Simplify

Introduction

Django simplify provides Ruby on Rails-like command line functionalities, models and helper functions so you can focus on development and removes the pain of repeating frequent actions.

Requirements

• Python 3.6 and above

• Django (tested with 3.1, probably works with any version that supports

  Python 3)

Installation

django-simplify can be installed via pip.

$ pip install django-simplify

Then just add simplify to your INSTALLED_APPS.

Learning Resources

• Tutorial videos can be found on this Youtube playlist.
• documentation link - https://django-simplify.readthedocs.io

Features

• timestamp for every model
• alphabetic filter for admin
• model, view, template and url route generator
• automatic import

Management commands

1. create_app

• automatically adds a urls.py file after app is created.
• adds newly created app in the settings.py file under INSTALLED_APPS
• creates index, edit, create and detail view and respective templates
• adds the app route to your project's urls.py file

Usage

$ python manage.py create_app <app_name>

2. create_model

Creates a model and their respective fields. the following types maps to respective Django model fields. It will also add the app to the django admin too.

• 121, o2o or set -> OneToOneField
• bool -> BooleanField
• date -> DateField
• datetime or dt -> DateTimeField
• dict or m2m -> ManyToManyField
• email -> EmailField
• file -> FileField
• list or fk -> ForeignKey
• float -> FloatField
• dec -> DecimalField
• img or image -> ImageField
• int -> IntegerField
• str or char -> CharField
• txt or text -> TextField

Usage

$ python manage.py create_app <app_name> <model_name> field_name:type field_name:type ...

an example

$ python manage.py create_app member Member first_name:text last_name:text age:int

will generate the following code in the member/models.py file

class Member(models.Model):
    first_name = models.CharField(max_length=50)
    last_name = models.CharField(max_length=50)
    age = models.IntegerField(default=0)

    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

    def __str__(self):
        return self.first_name

Note

The command uses the first specified field as the __str__ default.

Specifying relationships

Specifying ForeignKey, OneToOneField or ManyToManyField is quite easy. just add an =<related_model>. See example

$ python manage.py create_app <app_name> <model_name> field_name:type=related_model

# an example
# if the related model is in the same models.py file, specify it as app_name.Model
$ python manage.py create_app author Author name:char books:fk=Book # or
$ python manage.py create_app author Author name:char books:fk=author.Book

# if in a different app. (say book model)
# obviously you should be able to substitute fk with m2m, o2o, 121
$ python manage.py create_app author Author name:char books:fk=book.Book

will create the following

class Author(models.Model):
    name = models.CharField(max_length=50)
    books = models.ForeignKey('book.Book', on_delete=models.CASCADE)

    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

    def __str__(self):
        return self.name

3. create_view

Creates a view, generate its respective template and adds the path in the urls.py file

Usage

$ python manage.py create_view <app_name> <view_name>

an example

$ python manage.py create_view member MemberDetail


Helper models
################

- simplify.utils.TimeBasedModel
    - Provides the `created_at` and `updated_at` fields for timestamp

- simplify.utils.NamedTimeBasedModel
    - Provides the `name`, `created_at` and `updated_at` fields.

- simplify.utils.AlphaNumericFilterAdmin
    - when subclassed, it allows the items to be filtered alphabetically by either A-Z or 0-9
    - **Note**: for this to work, you must specify values for `alphanumeric_filter` in the model admin.


Usage
######

.. code-block:: python

  # models.py
  from simplify.utils import TimeBasedModel, NamedTimeBasedModel

  class MyModel(TimeBasedModel):
      extra_fields = ....



.. code-block:: python

  # admin.py
  from simplify.utils import AlphaNumericFilterAdmin

  class MemberAdmin(AlphaNumericFilterAdmin):
      alphanumeric_filter = ["first_name", "last_name", 'age'] # this part is what creates the filter
      list_filter = ['age']
      list_display = ['first_name', 'last_name',]

Todo

• add more helper functions
• add documentation

Note

This is still in early development mode. might have bugs. It works fine if you write good code and follow the django style of development. Please fork the project to make contributions
