The low-code for developers with yesterday's deadline

Viewflow is a low-code library for building business applications with Django. It gives you ready-made components for user management, workflows, and reporting. You write less code but keep full control. You can customize everything and connect it to your existing systems.

Build full-featured business applications in a few lines of code. Viewflow ships as one package with everything included. Each part works on its own, but they all work well together.

GPT assisted with Viewflow documentation: Viewflow Pair Programming Buddy

Viewflow comes in two versions:

• Viewflow Core: Open-source library with base classes. Build your own solution on top.
• Viewflow PRO: Full package with ready-to-use features and third-party integrations. Commercial license allows private forks and modifications.

• Modern, responsive interface with SPA-style navigation
• Reusable workflow library for BPMN processes
• Built-in CRUD for complex forms and data
• Reporting dashboard included
• Small, easy-to-learn API

Viewflow works with Python 3.8+ and Django 4.0+

Viewflow:

pip install django-viewflow

Viewflow PRO:

pip install django-viewflow-pro  --extra-index-url https://pypi.viewflow.io/<licence_id>/simple/

Add to INSTALLED_APPS in settings.py:

    INSTALLED_APPS = [
        ....
        'viewflow',
        'viewflow.workflow',  # if you need workflows
    ]

Here is a pizza ordering workflow example.

Viewflow provides a Process base model. Use jsonstore fields to store data without extra database joins:

    from viewflow import jsonstore
    from viewflow.workflow.models import Process

    class PizzaOrder(Process):
        customer_name = jsonstore.CharField(max_length=250)
        address = jsonstore.TextField()
        toppings = jsonstore.TextField()
        tips_received = jsonstore.IntegerField(default=0)
        baking_time = jsonstore.IntegerField(default=10)

        class Meta:
            proxy = True

Define a flow class with steps. Use CreateProcessView and UpdateProcessView for the forms:

    from viewflow import this
    from viewflow.workflow import flow
    from viewflow.workflow.flow.views import CreateProcessView, UpdateProcessView
    from .models import PizzaOrder

    class PizzaFlow(flow.Flow):
        process_class = PizzaOrder

        start = flow.Start(
            CreateProcessView.as_view(
                fields=["customer_name", "address", "toppings"]
            )
        ).Next(this.bake)

        bake = flow.View(
            UpdateProcessView.as_view(fields=["baking_time"])
        ).Next(this.deliver)

        deliver = flow.View(
            UpdateProcessView.as_view(fields=["tips_received"])
        ).Next(this.end)

        end = flow.End()

Register the workflow with the frontend:

    from django.urls import path
    from viewflow.contrib.auth import AuthViewset
    from viewflow.urls import Application, Site
    from viewflow.workflow.flow import FlowAppViewset
    from my_pizza.flows import PizzaFlow

    site = Site(
        title="Pizza Flow Demo",
        viewsets=[
            FlowAppViewset(PizzaFlow, icon="local_pizza"),
        ]
    )

    urlpatterns = [
        path("accounts/", AuthViewset().urls),
        path("", site.urls),
    ]

Run migrations, start Django, and open the browser. You can now create and track pizza orders through the workflow.
