Struct Model

pub struct Model {
    pub id: i64,
    pub assignment_id: i64,
    pub task_id: i64,
    pub path: String,
    pub created_at: DateTime<Utc>,
    pub updated_at: DateTime<Utc>,
}

Represents the output generated by the interpreter for an assignment memo.

Each output is linked to a specific assignment and task. Timestamps are included to track when the file was created and last updated.

Fields

id: i64

Primary key of the output.

assignment_id: i64

ID of the related assignment.

task_id: i64

ID of the related task.

path: String

Relative file path from the storage root.

created_at: DateTime<Utc>

Timestamp when the output was created.

updated_at: DateTime<Utc>

Timestamp when the output was last updated.

Implementations

impl Model

pub fn storage_root() -> PathBuf

Returns the root directory used for storing assignment submissions on disk.

Returns

• PathBuf pointing to the base directory.

Uses the ASSIGNMENT_STORAGE_ROOT environment variable if set, otherwise defaults to data/assignment_files.

pub fn full_directory_path(module_id: i64, assignment_id: i64) -> PathBuf

Constructs the full directory path for a memo output based on its assignment and task identifiers.

pub fn full_path(&self) -> PathBuf

Computes the absolute path to the stored output file on disk.

pub async fn save_file( db: &DatabaseConnection, assignment_id: i64, task_id: i64, filename: &str, bytes: &[u8], ) -> Result<Self, DbErr>

Saves a memo output file to disk and creates or updates its metadata in the database.

pub fn read_memo_output_file( module_id: i64, assignment_id: i64, file_id: i64, ) -> Result<Vec<u8>, Error>

Reads the contents of a memo output file from disk, given the module_id, assignment_id, and the file id (filename).

Trait Implementations

impl Clone for Model

fn clone(&self) -> Model

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Model

fn fmt(&self, f: &mut Formatter<'_>) -> Result

fn from(m: Model) -> Self

Converts to this type from the input type.

Instantiate a Model from a [QueryResult]

fn from_query_result_optional( res: &QueryResult, pre: &str, ) -> Result<Option<Self>, DbErr>

Transform the error from instantiating a Model from a [QueryResult] and converting it to an Option

fn from_query_result_nullable( res: &QueryResult, pre: &str, ) -> Result<Self, TryGetError>

Transform the error from instantiating a Model from a [QueryResult] and converting it to an Option

fn find_by_statement(stmt: Statement) -> SelectorRaw<SelectModel<Self>>

impl IntoActiveModel<ActiveModel> for Model

fn into_active_model(self) -> ActiveModel

Method to call to perform the conversion

impl ModelTrait for Model

type Entity = Entity

fn get(&self, c: <Self::Entity as EntityTrait>::Column) -> Value

Get the [Value] of a column from an Entity

fn set(&mut self, c: <Self::Entity as EntityTrait>::Column, v: Value)

Set the [Value] of a column in an Entity

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.

type Error = DbErr

The type returned in the event of a conversion error.

fn try_from(a: ActiveModel) -> Result<Self, DbErr>

Performs the conversion.
