Resumen
The Describe function returns the following properties for datasets that have attribute rules added to them.
Attribute rules can be added to a geodatabase feature class or table. The dataType returned is the dataType of the feature class or table.
Propiedades
| Propiedad | Explicación | Tipo de datos |
| batch (Sólo lectura) | Indicates whether the rule is executed in batch mode.
Calculation rules may return either true or false, but constraint rules will always return false, and validation rules will always be true. | Boolean |
| checkParameters (Sólo lectura) | A key-value pair of check parameters applicable only to Reviewer rules to store parameters. This is set by Data Reviewer when creating a rule. | Integer |
| creationTime (Sólo lectura) | The date and time the attribute rule was created. | DateTime |
| description (Sólo lectura) | The description of the attribute rule. | String |
| errorMessage (Sólo lectura) | If the attribute rule has a custom error message (that is, constraint rules), this property will return the error message that was assigned for this rule. | String |
| errorNumber (Sólo lectura) | If the attribute rule has a custom error number (that is, constraint rules), this property will return the error number that was assigned for this rule. | Long |
| evaluationOrder (Sólo lectura) | If the rule type is calculation, this value gives the order that the rule is executed. The evaluation order is based on the order that the rule was added to the dataset. For example, if Rule A is added before Rule B, the evaluation number will be lower for Rule A. | Long |
| excludeFromClientEvaluation (Sólo lectura) | Returns a Boolean describing whether the rule is excluded from client evaluation.
| Boolean |
| fieldName (Sólo lectura) | If the attribute rule is assigned to a field (that is, a calculation rule type), this property returns the field name. | String |
| id (Sólo lectura) | Returns the rule ID as an integer value. | Integer |
| isEnabled (Sólo lectura) | Returns a Boolean describing whether the rule is enabled.
| Boolean |
| name (Sólo lectura) | The name of the attribute rule. | String |
| referencesExternalService (Sólo lectura) | Indicates whether the rule references any external service. | Boolean |
| requiredGeodatabaseClientVersion (Sólo lectura) | The required geodatabase client version is set per rule, depending on which Arcade functions are used in the script expression. For example, if the script includes the Sequence operation, a 10.6.1 geodatabase is required. | String |
| scriptExpression (Sólo lectura) | The Arcade expression that defines the rule. Nota:This property is not available for Data Reviewer rules. | String |
| severity (Sólo lectura) | Defines the severity of the error. This property is applicable to validation rule types. | Integer |
| subtypeCode (Sólo lectura) | If the attribute rule is assigned to a subtype, this property returns the subtype code to which it is assigned. | Long |
| tags (Sólo lectura) | A set of tags that are used to identify the rule. | String |
| triggeringEvents (Sólo lectura) | The triggering events defined in the attribute rule. For example, the rule may be triggered by Insert, Update, or Delete events during editing. | String |
| type (Sólo lectura) | The type of the attribute rule. For example, a rule may be a calculation or constraint rule type. | String |
| userEditable (Sólo lectura) | Returns a Boolean describing whether the rule allows editing of the attribute field that is being modified by the rule.
| Boolean |

The following stand-alone Python script prints a report of the attribute rule properties for a feature class.
# Import the required modules
import arcpy
# Path to the input feature class or table
fc = "C:\\MyProject\\MyDatabase.sde\\myGDB.USER1.Building"
# Print a report of the attribute rule properties
attRules = arcpy.Describe(fc).attributeRules
print("- Attribute Rule Properties -")
