    11  # Tag Revision requests: Tag field
    12  
    13  This rule enforces that all Tag Revision methods have a `string tag`
    14  field in the request message, as mandated in [AIP-162][].
    15  
    16  ## Details
    17  
    18  This rule looks at any message matching `Tag*RevisionRequest` and complains if
    19  either the `tag` field is missing or it has any type other than `string`.
    20  
    21  ## Examples
    22  
    23  **Incorrect** code for this rule:
    24  
    25  ```proto
    26  // Incorrect.
    27  // Should include a `string tag` field.
    28  message TagBookRevisionRequest {
    29    string name = 1 [
    30      (google.api.field_behavior) = REQUIRED,
    31      (google.api.resource_reference).type = "library.googleapis.com/Book"
    32    ];
    33  }
    34  ```
    35  
    36  ```proto
    37  // Incorrect.
    38  message TagBookRevisionRequest {
    39    string name = 1 [
    40      (google.api.field_behavior) = REQUIRED,
    41      (google.api.resource_reference).type = "library.googleapis.com/Book"
    42    ];
    43  
    44    // Field type should be `string`.
    45    bytes tag = 2 [(google.api.field_behavior) = REQUIRED];
    46  }
    47  ```
    48  
    49  **Correct** code for this rule:
    50  
    51  ```proto
    52  // Correct.
    53  message TagBookRevisionRequest {
    54    string name = 1 [
    55      (google.api.field_behavior) = REQUIRED,
    56      (google.api.resource_reference).type = "library.googleapis.com/Book"
    57    ];
    58  
    59    string tag = 2 [(google.api.field_behavior) = REQUIRED];
    60  }
    61  ```
    62  
    63  ## Disabling
    64  
    65  If you need to violate this rule, use a leading comment above the message (if
    66  the `tag` field is missing) or above the field (if it is the wrong type).
    67  Remember to also include an [aip.dev/not-precedent][] comment explaining why.
    68  
    69  ```proto
    70  message TagBookRevisionRequest {
    71    string name = 1 [
    72      (google.api.field_behavior) = REQUIRED,
    73      (google.api.resource_reference).type = "library.googleapis.com/Book"
    74    ];
    75  
    76    // (-- api-linter: core::0162::tag-revision-request-tag-field=disabled
    77    //     aip.dev/not-precedent: We need to do this because reasons. --)
    78    bytes tag = 2 [(google.api.field_behavior) = REQUIRED];
    79  }
    80  ```
    81  
    82  If you need to violate this rule for an entire file, place the comment at the
    83  top of the file.
