Get methods: Resource reference

This rule enforces that the google.api.resource_reference on the name field of a Get RPC request message uses type, not child_type, as suggested in AIP-131.

Details

This rule looks at the google.api.resource_reference annotation on the name field of any message matching Get*Request and complains if it does not use a direct type reference.

Examples

Incorrect code for this rule:

// Incorrect.
message GetBookRequest {
  // The `google.api.resource_reference` annotation should be a direct `type`
  // reference.
  string name = 1 [
    (google.api.field_behavior) = REQUIRED,
    (google.api.resource_reference).child_type = "library.googleapis.com/Book"
  ];
}

Correct code for this rule:

// Correct.
message GetBookRequest {
  string name = 1 [
    (google.api.field_behavior) = REQUIRED,
    (google.api.resource_reference).type = "library.googleapis.com/Book"
  ];
}

Disabling

If you need to violate this rule, use a leading comment above the field. Remember to also include an aip.dev/not-precedent comment explaining why.

message GetBookRequest {
  // (-- api-linter: core::0131::request-name-reference-type=disabled
  //     aip.dev/not-precedent: We need to do this because reasons. --)
  string name = 1 [
    (google.api.field_behavior) = REQUIRED,
    (google.api.resource_reference).child_type = "library.googleapis.com/Book"
  ];
}

If you need to violate this rule for an entire file, place the comment at the top of the file.
