Ok, I think I've resolved that. I'm using both versions (6.0.2 and 5.4.3.2.1 - debugger issues) and in latter one I waas lacking that option. Go to Settings > Diagrams
, uncheck everything and apply
. You should be prompted about changes in workspace.xml
. Accept that and you should have all three diagrams options available now.
If this won't help - invalidate caches, I'm not sure if it will delete workspace.xml
. If not, delete .idea
directory from your project and let RubyMine index it once again and recreate workspace.xml
.
