Generate Mermaid Diagrams for Your Database

Appears to require running a python script ... 💭
Really wish there was automatic SQL import that would generate valid Mermaid ... 🙏

This looks promising: https://github.com/KarnerTh/mermerd and under active development. 🤞

Todo

• Make time to investigate / try this.
• Ideally we could:

1. Auto-generate the Mermaid for the Schema on GitHub CI after the Elixir/Phoenix tests are complete.
2. Upload the resulting Mermaid either to GitHub via automated PR or S3 if that proves too difficult
3. Have a static web page where anyone can inspect the latest ERD deployed for the App.

Isn't Ecto.ERD good enough for your usage?

@ndrean great question. Probably. Thanks for the reminder. 🎉

exports to mermaid but I don't like these diagrams. Dot is ok.

I made a "self reminder post" on this

@ndrean great post. Thanks for making it and sharing. 🚀
I've been creating the ERDs manually using the GUI tool ... e.g: /mvp/BUILDIT.md#2-create-schemas ⏳
Knew there had to be a better way; plenty of people face this problem. 👍

I do this kind of post just for myself because I tend to forget so glad it is understandable. For your use case, it's just 2 lines in the terminal: mix ecto..gen.erd and dot ....

In return, any guidance on your site for Changesets?
