Generate entity relationship based on model, Ruby on rails
During this time, I am in an internship program. There is a big concern, I have to work with a very big project, and there is no documentation. The number of tables in project’s database is more than 20, still no documentation.
A big nightmare for an intern one. It’s important to make an entity relationship diagram, at least with a hope that I can get cope easily with the project.
Game on!, There is a gem named
erd - url
Setup and Installation
- Install graphviz (fedora)
- Add gem erd to gem file
- Install bundle
Configuration file will be loaded at
...project_rails/.erdconfig, file config in the root of project will take
higher priority than in the home directory.
Generating entity diagram file
Entity diagram will be generated in the root directory of project.
