Struct UpdateOne 

pub struct UpdateOne<A: ActiveModelTrait>(/* private fields */);

A request to update an ActiveModel.

The primary key must be set. Otherwise, it’s impossible to generate the SQL condition and find the record. In that case, exec will return an error and not send any queries to the database.

If you want to use QueryTrait and access the generated SQL query, you need to convert into ValidatedUpdateOne first.

Implementations

impl<A> UpdateOne<A>

where A: ActiveModelTrait,

pub fn exec_without_returning<C>(self, db: &C) -> Result<UpdateResult, DbErr>

where C: ConnectionTrait,

Execute an UPDATE operation without a RETURNING clause, yielding an UpdateResult instead of the updated model. Returns DbErr::RecordNotUpdated if no row matches.

pub fn exec<C>(self, db: &C) -> Result<<A::Entity as EntityTrait>::Model, DbErr>

where <A::Entity as EntityTrait>::Model: IntoActiveModel<A>, C: ConnectionTrait,

Execute an UPDATE operation on an ActiveModel

impl<A: ActiveModelTrait> UpdateOne<A>

pub fn validate(self) -> Result<ValidatedUpdateOne<A>, DbErr>

Check whether the primary key is set and we can proceed with the operation.

Trait Implementations

impl<A: Clone + ActiveModelTrait> Clone for UpdateOne<A>

fn clone(&self) -> UpdateOne<A>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<A: Debug + ActiveModelTrait> Debug for UpdateOne<A>

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

Formats the value using the given formatter.

impl<A: ActiveModelTrait> TryFrom<UpdateOne<A>> for ValidatedUpdateOne<A>

type Error = DbErr

The type returned in the event of a conversion error.

fn try_from(value: UpdateOne<A>) -> Result<Self, Self::Error>

Performs the conversion.
