[−][src]Module wundergraph::query_builder::mutations
This module contains all functionality that is needed to implement mutations
In general mutations should just work without any additional work that writing some struct definition and deriving basic diesel for them For special cases a manual implementation of one of the for exported traits is required
Insert
The easiest way to provide a single table insert mutation is to crate a struct
with all corresponding fields that derive #[derive(Insertable, GrahpQLInputobject)]
#[derive(Insertable, GraphQLInputObject, Clone, Debug)] #[table_name = "heros"] pub struct NewHero { name: String, species: i32, home_world: Option<i32>, }
For more complex cases like inserts that involve multiple tables at one
implement HandleInsert
and
InsertHelper
manually
Update
Similar to Insert
operations the easiest way to provide a single table update
mutation is to create a struct with all corresponding fields that derive
#[derive(AsChangeset, GraphqlInputObject, Identifiable)]
#[derive(AsChangeset, GraphQLInputObject, Identifiable, Debug)] #[table_name = "heros"] pub struct HeroChangeset { id: i32, name: Option<String>, species: Option<i32>, home_world: Option<i32>, }
