Delete methods: Required fields

This rule enforces that all Delete standard methods do not have unexpected required fields, as mandated in AIP-135.

Details

This rule looks at any message matching Delete*Request and complains if it comes across any required fields other than:

Examples

Incorrect code for this rule:

// Incorrect.
message DeleteBookRequest {
  string name = 1 [(google.api.field_behavior) = REQUIRED];
  // Non-standard required field.
  bool allow_missing = 4 [(google.api.field_behavior) = REQUIRED];
}

Correct code for this rule:

// Correct.
message DeleteBookRequest {
  string name = 1 [(google.api.field_behavior) = REQUIRED];
  bool allow_missing = 4 [(google.api.field_behavior) = OPTIONAL];
}

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 DeleteBookRequest {
  string name = 1 [(google.api.field_behavior) = REQUIRED];
  // (-- api-linter: core::0135::request-required-fields=disabled
  //     aip.dev/not-precedent: We really need this field to be required because
  // reasons. --)
  bool allow_missing = 4 [(google.api.field_behavior) = REQUIRED];
}

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