Django Migration Dependency Graph

This is an app that helps developers understand how their migrations are interconnected across their apps, serving as a tool to identify possible circular dependencies when squashing them.

Installation

pip install django-migration-dependencies

Quick start

1. Add "migrations-graph" to your INSTALLED_APPS setting like this:

   INSTALLED_APPS = [ ... 'migrations-graph', ]

2. Include the polls URLconf in your project urls.py like this::

   import migrations_graph.urls path('migrations-graph/', include('migrations_graph.urls')),

3. Start the development server.

4. Visit http://127.0.0.1:8000/migrations_graph/ to see the graph.

Caveats

• Some times you won't get a graph for some reason and find an error in the browser's console Cannot set property 'order' of undefined.... Change the layout by passing the query param ?layout=breadthfirst. For more info see https://github.com/dagrejs/dagre/issues/234

Disclaimer

This is a real quick hack to help a one-time need (for now). You won't find tests here (...that is, for now).
