Domain Modeling Diagram!

As i was trying to make relationships while modeling a new project i’m working on, it crossed my mind to have a visual representation of how it would all look like. I had already made my mind-map before starting to work on the project but that did not answer the question “How can i visualize existing projects?”

So i decided to do some digging around and it did not take me long to find out 2 of my favorite Gems.

Railroady & Rails-erd

My personal favorite is Railroady, i just think it has more options out of the box when compaired to Rails-erd.

Here is a small tutorial on how to set it all up in an existing rails project.

Step 1

install comming soon…

Step 2

configure comming soon…

Step 3

see comming soon…

Now lets automate it all!!

I created this bash script to do all the work for us.
