CLI for managing Django projects

Project description

Djangle-CLI [WIP]

CLI that handles creating and managing Django projects




Install via pip:

pip install djangle-cli

Install from source:

git clone
cd djangle
pip install .


destroy   Removes models, serializers, and other...
generate  Adds models, routes, and other resources
new       Creates projects and apps


The new command (abbreviated n) can be used to start new projects as well as new applications. The command tries to simplify how a project is created as well as the applications contained in it. Here's an example of such simplification:

Suppose you want to start a new project and want to create two apps within it:

django-admin startproject API
django-admin startapp developers
django-admin startapp blog

The equivalent command in the Djangle-CLI is:

D new project API developers blog

Specifying an app when creating a project is optional, but you're likely to need to create one inside of your project directory, so the CLI can handle the creation of all of your apps as arguments after your project name.

Project structure

This CLI makes some assumptions about the structure of your Django project.

  1. It assumes that your apps are one level below the root of your project directory, one level below where is. For example:
│   ├──
│   ├── My_Application_1
│   ├── My_Application_2
│   ├──
│   ├──
│   └──
└── requirements.txt
  1. It assumes that your app resources are grouped together by type in packages. For example:
├── admin
├── forms
├── migrations
├── models
├── serializers
├── templates
├── tests
├── views
└── viewsets
  1. Each class representing a model, serializer, viewset, or form is located in its own Python file. For example:

This is done in order to aid the CLI with the creation and deletion of files in the project as we'll see under the generate and destroy commands.


The generator is accessible through the generate command (abbreviated g). It can be used to create the following:

  • form
  • model
  • serializer
  • view
  • viewset
  • template

If you need all of the above, you can use the resource sub-command instead of running the individual sub-commands listed above.

The generator supports --dry-run, meaning it can provide you with the console log of the desired command without creating any files in your directory structure. This is useful if you want to see what a command accomplishes before fully committing to it.

Note: no current support for --dry-run when scaffolding a resource.

Generating Models

In order to generate a model, specify the type identifier and then the name of the attribute field. Type identifiers are abbreviated to a more generic name that omits the word Field. The input here is case-insensitive, but the fields will be properly CamelCased in the corresponding Python file as in the example below:

D generate model album text:title image:artwork bool:is_compilation

This would add the following model under the models directory:

import uuid
from django.db import models

class Album(models.Model):
    title = models.TextField(blank=True)
    artwork = models.ImageField(blank=True, upload_to='uploads')
    compilation = models.BooleanField(default=False)

    # Default fields. Used for record-keeping.
    uuid = models.UUIDField(default=uuid.uuid4, editable=False)
    created_at = models.DateTimeField(auto_now_add=True, editable=False)
    updated_at = models.DateTimeField(auto_now=True, editable=False)

    class Meta:
        db_table = 'app_name_albums'
        ordering = ['-created_at']

    def save(self, *args, **kwargs):
          super().save(*args, **kwargs)

    def __str__(self):
        return f'{self.uuid}


As one can see, class Meta and _str_ are added to a model by default along with uuid, created_at and updated_at fields. The db_table name is inferred from the name of the app and the current model while the ordering attribute is defined based on the default created_at field.


If a relationship identifier is passed, the attribute name will be used as the name of the model it relates to. Specifying a relationship also adds an import statement to the model file. For example:

D generate model album fk:artist

Would create an artist attribute like so:

import uuid
from django.db import models
from .artist import Artist

class Album(models.Model):
    artist = models.ForeignKey(Artist, related_name='albums', on_delete=models.DO_NOTHING)

    # Default fields. Used for record-keeping.
    uuid = models.UUIDField(default=uuid.uuid4, editable=False)
    created_at = models.DateTimeField(auto_now_add=True, editable=False)
    updated_at = models.DateTimeField(auto_now=True, editable=False)

    class Meta:
        db_table = 'album'
        ordering = ['-created_at']

    def save(self, *args, **kwargs):
          super().save(*args, **kwargs)

    def __str__(self):
        return f'{self.uuid}'

Supported relationship identifiers:

  • FK: ForeignKeyField
  • One: OneToOneField
  • Many: ManyToManyField

Generating Serializers and Viewsets

If you are working on an API and use the Django REST Framework to support your backend, you can also use the Djangle-CLI to create serializers and viewsets.

The commands are much like the ones used to generate a model except you don't specify any model attributes, just the model name:

D generate serializer album

Which outputs:

from rest_framework import serializers
from ..models.album import Album

class AlbumSerializer(serializers.ModelSerializer):

    # Add related fields below:
    # Example relation fields are:
    # -- HyperlinkedIdentityField
    # -- HyperlinkedRelatedField
    # -- PrimaryKeyRelatedField
    # -- SlugRelatedField
    # -- StringRelatedField

    # You can also create a custom serializer, like so:
    # likes = LikeSerializer(many=True)

    class Meta:
        model = Album
        fields = "__all__"

Similarly, a viewset can be generated like so:

D generate viewset album

Which in turn would generate the following viewset:

from rest_framework import viewsets
from rest_framework import permissions
from ..models.album import Album
from ..serializers.album import AlbumSerializer

class AlbumViewSet(viewsets.ModelViewSet):
    queryset = Album.objects.all()
    serializer_class = AlbumSerializer
    permission_classes = [permissions.IsAuthenticatedOrReadOnly]

Destroyer [WIP]

This command can be used to undo all that a generator can generate. So, following our example Album model, one can remove it from the project simply by running:

D destroy model album

Supported options:

  • form
  • model
  • resource
  • view
  • viewset
  • serializer
  • template
