General Syntax
All plan metadata references follow the following basic syntax:
{{$plan.path.to.reference}}
All references can be entered with
$in the Designer Cloud application. These references are turned into{{$in the code definition. The double-curly braces forms the environment for metadata replacement.Tip: In the Designer Cloud application, you can start by typing
$.- Nodes in the tree are separated with a
.period.
Reference values that contain whitespace must be listed in the following manner:
{{$plan.path['path with white space in it'].rest.of.path}}
Notes:
- In the Designer Cloud application, you can use double-quotes when specifying a whitespace value. However, these double-quotes get escaped in the actual request. It is safer and more consistent to use single quotes.
Whitespace values typically appear when referencing the display name values for underlying objects, like recipes executed as part of a flow task.
$plan References
These references apply to the plan definition or current plan run.
Text to enter:
$plan.
| Reference | Description |
|---|---|
| name | Name of the plan that is run. |
| duration | Length of time that the plan ran or has run so far Tip: To return a more readable form of this duration value, use the following reference: {{$plan.duration|humanizeDuration}}
|
| startTime | Timestamp for when the plan run began |
| runId | Internal identifier for this run of the plan |
| user | Internal identifier of the user who launched this run. |
| taskCount | Count of tasks in the plan run. |
$http References
These references apply to HTTP tasks in the plan run.
Enter the following, after which you can see the two-letter codes for the HTTP tasks that have already executed in the current plan run:
$http_ax.
| Reference | Description |
|---|---|
| name | Name of the HTTP task |
| status | Current status of the task execution |
| duration | Length of time that the task ran or has run so far |
| startTime | Timestamp for when the task began. A null value if the task has not begun. |
| endTime | Timestamp for when the task ended. A null value if it has not ended yet. |
| statusCode | Status code (if any) returned from the receiving endpoint |
| response | Response information. See below. |
Response references
These references apply to the response returned as part of the task execution.
Enter the following, after which you can see the two-letter codes for the HTTP tasks that have already executed in the current plan run:
$http_ax.response.
| Reference | Description |
|---|---|
| body | Body of the response |
| json | JSON-formatted version of the response |
| headers | Headers returned with the response |
$slack References
You can reference metadata from Slack tasks in the current plan run using the following reference types:
$slack_ax.
Supported metadata is identical to the metadata for HTTP tasks. See the previous section for details.
$flow References
These references apply to flow tasks in the plan run.
Enter the following, after which you can see the two-letter codes for the HTTP tasks that have already executed in the current plan run:
$flow_ax.
| Reference | Description |
|---|---|
| name | Name of the flow task |
| status | Current status of the task execution |
| duration | Length of time that the task ran or has run so far |
| startTime | Timestamp for when the task began. A null value if the task has not begun. |
| endTime | Timestamp for when the task ended. A null value if it has not ended yet. |
| jobIds | Internal identifiers for the jobs that were run as part of this flow task |
| flowName | Name of the flow underlying this flow task |
| output | Metadata from the flow task's output. See below. |
| params | Parameters created in the flow can be referenced in the task. |
Output references
These references apply to the outputs that are generated in the flow tasks of the plan run.
Enter the following for flow task 7p with output My Output Name:
$flow_7p['My Output Name'].
| Reference | Description |
|---|---|
| name | Name of the flow |
| status | Current status of the flow |
| duration | Length of time that the flow execution ran or has run so far |
| startTime | Timestamp for when the flow execution began. A null value if the run has not begun. |
| endTime | Timestamp for when the flow execution ended. A null value if it has not ended yet. |
| lastUpdate | Timestamp for when the flow was last modified |
| jobId | Internal identifier for the job that was run or is running for the flow |
| user | Internal identifier for the user who executed the job |
| jobType | |
| fileSize | If the output generates a file or files, this value captures the size in KB of the output. |
| environment | Running environment where the job was executed |
| columnCount | Count of columns generated in the output |
| rowCount | Count of rows generated in the output |
| dataTypeCount | Count of Alteryx data types detected in the output |
| validValuesCount | Count of valid values in the output |
| mismatchedValuesCount | Count of mismatched values in the output |
| emptyValuesCount | Count of missing or empty values in the output |
| columns | Column information from the selected output for the flow. |
| sources | Source filename and table information from the imported datasets. |
Additional References
Plan metadata reference information leverages the Nunjucks templating language, which provides additional capabilities such as loops, conditions, filters, and helper functions.
NOTE: These additional capabilities are available through the language, but their implementation in the Designer Cloud application has not been certified. For Nunjucks capabilities not listed on this page, you should experiment with them in a development environment first.
For more information, see https://mozilla.github.io/nunjucks/templating.html.
