Ecto ERD - Entity-Relationship Diagram generator for Ecto

[fuelen]

Thank you for detailed feedback!

@Eiji

By default do not include migrations schema as it’s used only by ecto internally

Sounds reasonable, but if there is an app that works with this table somehow, then we’d have to add more options to show the schema again. As for now, it can be easily removed using config file:

[
  map_node: fn
    %{source: "schema_migrations"} -> nil
    node -> node
  end
]

• Can you change the id to something like: id : id (schema_name.table_name) (as passed to schema macro)?

Primary keys are not required. Seems like you just want to see a table name. I think there are better ways of doing this, like add one more row which shows schema prefix and table name.

@Eiji

Can you also change other id fields to something like field_name : id (schema_name.table_name.foreign_key_field_name)

It is a bit noisy. The downside of PlantUML is that it doesn’t support precise connections between fields (using arrows), as it is done in our dot renderer.
What do you like in PlantUML the most? AFAIK, it uses Graphviz under the hood, and maybe we can modify/add an option to our dot renderer to have similar experience.

@Eiji

Could you by default use last 2 parts of Elixir module, so we have just short MyContext.MySchema instead of MyApp.MyContext.MySchema?

That’s a good idea to have an ability to format module name, but definitely not by default, as such names can overlap.
