ER Flow for Django Developers

Visualize your Django models before writing a single migration

Django's ORM is powerful, but complex model graphs become impossible to reason about in code alone. ER Flow gives Django developers a visual canvas to design the full data model — tables, foreign keys, ManyToManyFields, indexes — before touching models.py. Reverse-engineer existing Django projects by importing their SQL schema and see years of migrations collapse into one clear diagram.

Benefits

Visualize Django model relationships — ForeignKey, OneToOneField, ManyToManyField — as a clean ER diagram
SQL import reverse-engineers any existing Django app's database into the visual canvas in seconds
Design junction tables for ManyToManyField with through= models and see the full relationship graph
Plan db_index=True and unique_together constraints visually before writing model Meta classes
Real-time collaboration so multiple Django developers design the model layer together without conflicts
AI via MCP Server scaffolds new Django app schemas from plain-English feature descriptions

How It Works

1

Import

Run manage.py sqlmigrate or pg_dump and paste the SQL into ER Flow. Your entire Django schema appears on the canvas.

2

Visualize

See every ForeignKey, ManyToManyField through-table, and index rendered as a navigable ER diagram.

3

Design

Add new app models as tables. Define columns and relationships visually, then translate them directly to Django model fields.

4

Review

Share the diagram link with your team for schema reviews before anyone runs makemigrations.

5

Migrate

Generate SQL from the diff, validate it against your Django models, then run migrate on your target environment.
