We’ve always considered RubyMine’s Model Dependency Diagram a killer feature.
To make it even more killing we’ve made some small but nice changes just recently.
1. System default DB fields (id, created_at, updated_at) are now hidden by default and can be shown if needed
2. Relations are now more informative as they consider the inheritance of models
3. Some performance improvements were also made making the diagram load faster.
The new functionality will be available in the nearest RubyMine Beta update. Stay tuned for news on this blog!
