BREAD Engine

This package provides functionality to create django database applications in a quick and customizable way. Similar concept are CRUD (create-read-update-delete) frameworks or RAD (rapid application development) tools. BREAD is also partly a replacement of the django-admin interface, however, there is no API compatability to it.

Installation

pip install basx-bread

Quickstart

The following are the required step to get a new project quickly up and running. For seasoned Django users there should be nothing new for the most parts. In that case only the section Registering the UI might be worth reading.

Setup

    python3 -m venv .venv
    . .venv/bin/activate # this is for bash, for windows use the script .venv/bin/Activate.ps1, there are also scripts for csh and fish
    pip install basx-bread # should run without problems, but users reported problems in some Mac setups due to native libraries missing
    django-admin startproject --template $( pip show basx-bread | grep '^Location: ' | cut -c 11- )/bread/resources/project_template/ myproject . # template-project for bread

    # adding a Django "app", Django projects consist of different apps with different models, pretty standard
    # can also be achieved with "python manage.py startapp mymodels" but it would create a few unnecessary files
    mkdir mymodels mymodels/migrations
    touch mymodels/__init__.py mymodels/migrations/__init__.py
    echo -e 'from django.apps import AppConfig\n\n\nclass Mymodels(AppConfig):\n    name = "mymodels"' > mymodels/apps.py

After this the file mymodels/models.py needs to be created and filled with your database models. Then add "mymodels" to the list of INSTALLED_APPS inside myproject/settings/base.py.

Registering the UI

In order to get started with the UI quickly the following code can be put into mymodels/urls.py. The code below assumes there exists a single model inside mymodels/models.py called MyModel.

    from bread.utils import quickregister
    from . import models

    urlpatterns = []
    quickregister(urlpatterns, models.MyModel)

The root URL list in myproject/urls.py needs to be extended with an item path("myapp", include("mymodels.urls")).

Running the application

Finally run the following commands to initialize the database and start the development server.

    python manage.py makemigrations
    python manage.py migrate
    python manage.py createsuperuser
    python manage.py runserver

The application can now be accessed via http://127.0.0.1:8000.
