Create methods: Resource reference

This rule enforces that all Create standard methods have google.api.resource_reference on their string parent field, as mandated in AIP-133.

Details

This rule looks at the parent field of any message matching Create*Request and complains if it does not have a google.api.resource_reference annotation.

Examples

Incorrect code for this rule:

// Incorrect.
message CreateBookRequest {
  // The `google.api.resource_reference` annotation should also be included.
  string parent = 1 [(google.api.field_behavior) = REQUIRED];
  Book book = 2;
}

Correct code for this rule:

// Correct.
message CreateBookRequest {
  string parent = 1 [
    (google.api.field_behavior) = REQUIRED,
    (google.api.resource_reference).type = "library.googleapis.com/Publisher"
  ];
  Book book = 2;
}

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 CreateBookRequest {
  // (-- api-linter: core::0133::request-parent-reference=disabled
  //     aip.dev/not-precedent: We need to do this because reasons. --)
  string parent = 1 [(google.api.field_behavior) = REQUIRED];
  Book book = 2;
}

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