Django Model Lens

A VS Code extension that brings inline intelligence to Django projects — reference counts, URL route mapping, and model/method visual anchors, all without leaving your editor.

Features

Reference Counts

• Shows N references as a CodeLens above every class and def declaration in Python files
• Click the lens to open a custom references panel

• Each row shows the file path, line number, and a code preview — click to jump directly to that location
• Works without Pylance — falls back to a built-in workspace-wide grep scanner when no language server is active
• Automatically refreshes when files are saved or deleted

Reverse URL Routing Mapper

Displays the mapped URL pattern(s) directly above each Django view, so you never have to switch to urls.py to look up a route.

• Function-based views — shows the registered URL and HTTP methods detected from @api_view
• Class-based views — shows the URL and HTTP methods defined on the class (get, post, delete, …)
• DRF ViewSets — shows per-action lenses (list, create, retrieve, update, partial_update, destroy) with the correct list or detail URL derived automatically
• Click any lens to jump to the matching path() or router.register() call in urls.py
• Supports path(), re_path(), and DRF DefaultRouter / SimpleRouter

Model Anchor Badges (models.py)

Adds gutter icons and CodeLens badges in models.py to make the file easier to scan at a glance.

Icon	Appears on	Meaning
	Every class Foo(Model): line	Marks a Django model class
	Every def inside a model	Marks a model method or manager

• $(database) Model · ClassName CodeLens badge above each model class — a non-clickable visual anchor that keeps model names visible without scrolling
• Field reference counts — shows N references above every models.Field(…) assignment (e.g. username = models.CharField(...)) so you can see where each field is used across the project
• Method reference counts — shows N references above every method defined inside a model class; click to open the references panel

CBV Attribute Gutter Icons (views.py)

Adds colored gutter icons next to class-based view attributes in views.py for quick visual scanning.

Icon	Attribute	Meaning
	model = …	The Django model this view reads from or writes to
	template_name = …	The HTML template rendered by this view
	context_object_name = …	The variable name used to access the object in the template

Requirements

• VS Code 1.118.0 or later
• A Django project with urls.py and views.py / models.py files
