`create(parent, body=None, tagTemplateFieldId=None, x__xgafv=None)`

    Creates a field in a tag template. You must enable the Data Catalog API in the project identified by the `parent` parameter. For more information, see [Data Catalog resource project](https://cloud.google.com/data-catalog/docs/concepts/resource-project).

    Args:
      parent: string, Required. The name of the project and the template location [region](https://cloud.google.com/data-catalog/docs/concepts/regions). (required)
      body: object, The request body.
        The object takes the form of:

    { # The template for an individual field within a tag template.
      "description": "A String", # The description for this field. Defaults to an empty string.
      "displayName": "A String", # The display name for this field. Defaults to an empty string. The name must contain only Unicode letters, numbers (0-9), underscores (_), dashes (-), spaces ( ), and can't start or end with spaces. The maximum length is 200 characters.
      "isRequired": True or False, # If true, this field is required. Defaults to false.

For instance: service Foo { rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty); } The JSON representation for `Empty` is empty JSON object `{}`.
    }

`patch(name, body=None, updateMask=None, x__xgafv=None)`

    Updates a field in a tag template. You can't update the field type with this method. You must enable the Data Catalog API in the project identified by the `name` parameter.

      updateMask: string, Optional. Names of fields whose values to overwrite on an individual field of a tag template. The following fields are modifiable: * `display_name` * `type.enum_type` * `is_required` If this parameter is absent or empty, all modifiable fields are overwritten. If such fields are non-required and omitted in the request body, their values are emptied with one exception: when updating an enum type, the provided values are merged with the existing values. Therefore, enum values can only be added, existing enum values cannot be deleted or renamed. Additionally, updating a template field from optional to required is *not* allowed.
