generate queries for interfaces #280

Open tobiasfeil opened 4 years ago

tobiasfeil commented 4 years ago

I'm currently modeling a scenario in this way:

interface Person {
    id: ID!
}

type Student implements Person @model {
    id: ID!
}

type StaffMember implements Person @model {
    id: ID!
}

I would like to be able to call getPerson from the frontend, and then handle the data depending on the type name.

An alternative approach that would also solve my problem would be to enable this behavior for unions.

Not really a codegen issue for now. The graphql operation doc is generated based on output of transformer. getXXX queries are auto-generated by @model in graphql-transformer, from which there is a limitation that it cannot be used on an interface for now. One possible solution is that the model directive(or a new directive for interface) will add get queries for the related interface. FYI there is an ongoing RFC for transformer V2 here: aws-amplify/amplify-cli#6217
