Comment Tags

If your database has over hundreds of models, none of automatic ERD generators can express them perfect. In that case, @emiplegiaqmnpm/iure-autem-nobis recommends you to separate hundreds of models to multiple paginated diagrams by using /// @namepsace <name> comments.

When you write /// @namespace <name> comment on models, they would be separated to proper sections of markdown document. For reference, you can assign multiple @namespaces to a model, and if you do not assign any @namespace to a model, it would be assigned to default tag.

Also, if you use @erd <name> instead of @namespace <name>, target model would be expressed only at ERD. It would not be appeared to the markdown content section. Otherwise, @describe <name> tag will show the model only at markdown content section, not at ERD.

• @namespace <name>: Both ERD and markdown content
• @erd <name>: Only ERD
• @describe <name>: Only markdown content
• @hidden: Neither ERD nor markdown content
• @minItems 1: Mandatory relationship when 1: N (||---|{)

/// Both description and ERD on Actors chatper.
///
/// Also, only ERD on Articles and Orders chapters.
///
/// @namespace Actors
/// @erd Articles
/// @erd Orders
model shopping_customers {
  /// The tag "minItems 1" means mandatory relationship `||---|{`.
  ///
  /// Otherwise, no tag means optional relationship `||---o{`.
  ///
  /// @minItems 1
  login_histories shopping_customer_login_histories[]
}

/// Only description on Actors chapter.
///
/// @describe Actors
model shopping_customer_login_histories {}

/// Only ERD on Articles chapter.
///
/// @erd Articles
model shopping_sale_reviews {}

/// Never be shown.
///
/// @hidden
model shopping_sale_hits {}

Additionally, when defining 1: N relationship, you can specify the N position to be whether optional or mandatory. If you want to configure the N position to be mandatory, just write the @minItems 1 comment tag. Otherwise the N position is optional, you don't need to do anything.

model shopping_sale_units {
    /// @minItems 1
    stocks shopping_sale_snapshot_unit_stocks[];
    options shopping_sale_snapshot_unit_options[]; // optional
}
model shopping_sale_snapshot_unit_stocks {}
model shopping_sale_snapshot_unit_options {}
