Diagrams
RubyMine lets you utilize UML diagrams to analyze Ruby classes, Rails models, gem dependencies, and so on. Depending on the project type and current context (for example, a file/folder selected in a project view or a caret position in the editor), you can use the following diagram types:
Ruby class diagram
Rails model dependency diagram
Gem dependency diagram
Show a class diagram
To display a diagram for a class, do the following:
Select the file containing the required class in the Project view Alt+1 or open the class in the editor.
From the context menu, select
Ctrl+Alt+Shift+U or Ctrl+Alt+U.In the invoked popup, select Ruby Class Diagram and press Enter.
RubyMine will show the class diagram.
You can edit a generated diagram in various ways: add Space or remove Delete classes, display methods and class variables, add notes, and so on.
