I'm trying to figure out if there are any applications (SaaS or otherwise) that offer a basic graphical user interface for building out all the necessary scaffolding of a Rails or Node.js app from a flow-chart type of interface?
I remember Visual Studio had something like this for building database structures...why wouldn't there be something that does this for Rails or Node.js?
RailsModels purports to do this, but I find the interface is quite cumbersome.
If you just want to generate the diagrams from existing models for visualization, RailRoad and RubyMine Data Sources Tool can do this. But, neither offer a method for generating models from the GUI.
You are thinking of the Entity Model Designer (or possibly the older dataset designer), and I do not know of any Rails tools that offer similar functionality. As to why, I am not sure. I could comment, but it would be a guess, and probably be flamebait.
