Pull Request Overview

Adds a new --exclude (-e) option to the graph_transitions management command so users can omit named transitions from the generated graph.

• Introduce --exclude flag in argument parser and propagate it to generate_dot
• Update generate_dot to skip transitions listed in exclude
• Refactor tests to loop over models and add a test_exclude, plus document the flag in README

• The help text for the --exclude flag could be clearer by indicating that multiple transition names should be comma-separated and that whitespace will be trimmed. For example: help="Comma-separated list of transition names to ignore (whitespace will be trimmed)."

• The test_exclude test currently only invokes the command without verifying its effect. Consider capturing the command output and asserting that the specified transitions are indeed omitted from the generated graph data.

[Copilot]

Parsing the exclude option with raw split may include empty strings and leading/trailing whitespace, causing mismatches. Consider using options['exclude'].split(',') if options['exclude'] else [] and stripping each entry (e.g., [name.strip() for name in ... if name.strip()]) before passing to generate_dot.

Suggested change

	dotdata = generate_dot(fields_data, ignore_transitions=options["exclude"].split(","))
	exclude_transitions = [name.strip() for name in options["exclude"].split(",") if name.strip()] if options["exclude"] else []
	dotdata = generate_dot(fields_data, ignore_transitions=exclude_transitions)
