Struct ManyToManyDefinition 

pub struct ManyToManyDefinition {
    pub entity_a: String,
    pub entity_b: String,
    pub junction_table: Option<String>,
    pub entity_a_field: String,
    pub entity_b_field: String,

Many-to-many relationship definition

Represents a many-to-many relationship between two entities using a junction table. For example, Users and Roles with a user_roles junction table.

Fields

entity_a: String

First entity name

entity_b: String

Second entity name

junction_table: Option<String>

Junction table name (auto-generated if not provided) Format: “{entity_a}{entity_b}” or “{entity_b}{entity_a}” (alphabetically sorted)

entity_a_field: String

Foreign key field name in junction table pointing to entity_a

entity_b_field: String

Foreign key field name in junction table pointing to entity_b

on_delete_a: CascadeAction

Cascade action on delete for entity_a

on_delete_b: CascadeAction

Cascade action on delete for entity_b
