Using with changesets

[ElysaSrc]

Maybe it's not an issue, but I cannot figure out how to use this library with Diesel Changesets ?

I have the following Changeset:

#[derive(AsChangeset, Debug)]
#[diesel(table_name = entities)]
pub struct EntityChangeSet {
    pub display_name: Option<String>,
    pub category_id: Option<Uuid>,
    pub data: Option<Value>,
    pub locations: Option<MultiPoint<Point>>,

    last_update_by: Option<Uuid>,
    updated_at: Option<chrono::NaiveDateTime>,
}

It outputs the following error:

error[E0277]: the trait bound `postgis_diesel::types::MultiPoint<postgis_diesel::types::Point>: AppearsOnTable<schema::entities::table>` is not satisfied
  --> src/models/entities.rs:31:10
   |
31 | #[derive(AsChangeset, Debug)]
   |          ^^^^^^^^^^^ the trait `AppearsOnTable<schema::entities::table>` is not implemented for `postgis_diesel::types::MultiPoint<postgis_diesel::types::Point>`
   |

Is there a way for this library to support Changesets ?

Hi @ElysaSrc, can you provide complete minimal code example to reproduce that compilation error? I've tried to add AsChangeset derive into test structures like so, in integration_test.rs

#[derive(Insertable, AsChangeset)]
#[diesel(table_name = geometry_samples)]
struct NewGeometrySample {
    name: String,
    point: Point,
    point_z: PointZ,
    point_m: PointM,
    point_zm: PointZM,
    linestring: LineString<Point>,
    polygon: Polygon<Point>,
    multipoint: MultiPoint<Point>,
    multiline: MultiLineString<Point>,
    multipolygon: MultiPolygon<Point>,
    geometrycollection: GeometryCollection<Point>,
    geometrycontainer: GeometryContainer<Point>,
}

It compiled without errors.
