Struct orma::DbJoin

pub struct DbJoin<A> where
    A: DbData + Serialize + DeserializeOwned,  {
    pub sorting: Vec<String>,
    pub items: Vec<DbEntity<A>>,
    // some fields omitted
}

This struct is used to create a join between DbEntyty elements and JoinBuilder is used to create a DbJoin instance.

sorting parameter (such as vec!["data->>'first_name'", "data->>'last_name' DESC"]) take effect after a call to reload method.

items can be persisted to db after a call to save_items method.

See JoinBuilder for more info

Fields

sorting: Vec<String>

Used to provide a sorting method on data fetching.

vec!["data->>'first_name'", "data->>'last_name' DESC"];

items: Vec<DbEntity<A>>

Items for this relation over the DbEntity source that has been provided.

Methods

impl<A> DbJoin<A> where
    A: DbData + Serialize + DeserializeOwned, 

pub async fn reload<'_, '_>(
    &'_ mut self,
    conn: &'_ Connection
) -> Result<(), DbError>

This method reloads items field for the given join using the current sorting field.

pub async fn save_items<'_, '_>(
    &'_ self,
    conn: &'_ mut Connection
) -> Result<(), DbError>

This method saves the items for the given join to the DB.
