#[changeset_for(table_name)] only implements save_changes if there is a field called id on the struct

[weiznich]

The documentation states that save_changes is implemented if the struct contains a field called like the primary key:

If the struct has a field for the primary key, an additional function, save_changes<T: Queryable<..>>(&self, connection: &Connection) -> QueryResult, will be added to the model. This will persist any changes made, and return the resulting record. It is intended to be a shorthand for filtering by the primary key.

Codegen implements save_changes only if there is a field called id. Either we should fix the documentation or we add support for custom primary keys here.
