Struct Model

pub struct Model {
    pub user_id: i64,
    pub module_id: i64,
    pub role: Role,
}

The central table for user-module-role relationships. Replaces old module_lecturers, module_tutors, and module_students.

Fields

user_id: i64

User ID (foreign key to users)

module_id: i64

Module ID (foreign key to modules)

role: Role

Role type: Lecturer, Tutor, or Student

Implementations

impl Model

Additional CRUD logic and utilities for user_module_roles.

pub async fn assign_user_to_module( db: &DatabaseConnection, user_id: i64, module_id: i64, role: Role, ) -> Result<Self, DbErr>

Assign a user to a module with a specific role.

pub async fn remove_user_from_module( db: &DatabaseConnection, user_id: i64, module_id: i64, ) -> Result<DeleteResult, DbErr>

Remove a user from a specific module.

pub async fn get_all(db: &DatabaseConnection) -> Result<Vec<Self>, DbErr>

Get all role assignments.

pub async fn get_users_by_module_role( db: &DatabaseConnection, module_id: i32, role: Role, ) -> Result<Vec<Self>, DbErr>

Get all users assigned to a module under a specific role.

pub async fn get_modules_by_user_role( db: &DatabaseConnection, user_id: i32, role: Role, ) -> Result<Vec<Self>, DbErr>

fn find_related<R>(&self, _: R) -> Select<R>

where R: EntityTrait, Self::Entity: Related<R>,

Find related Models

fn find_linked<L>(&self, l: L) -> Select<<L as Linked>::ToEntity>

where L: Linked<FromEntity = Self::Entity>,

impl PartialEq for Model

fn eq(&self, other: &Model) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Performs the conversion.
