Event based trigger
Triggered based on the user defined event such as Tailor DB record creation EventType: "tailordb.type_record.created"
.
Tutorial steps
To create an event based trigger, you'll need to:
- Activate the Executor service
- Add the trigger in
executor.cue
manifest file - Enable
PublishRecordEvents
settings - Apply the change using
tailorctl
- Verify the trigger
1. Activate the Executor service
To activate the Executor service, add executor
service to the list of services in the workspace.cue
file as the following.
<span><span style="color: var(--shiki-token-keyword)">package</span><span style="color: var(--shiki-color-text)"> v2</span></span>

<span><span style="color: var(--shiki-color-text)">}</span></span>
<span></span>
2. Add the trigger in executor.cue
manifest file
To add the triggerCreateShipmentWithEvent
trigger, define the trigger in the executor.cue
manifest file.
<span><span style="color: var(--shiki-token-keyword)">package</span><span style="color: var(--shiki-color-text)"> executor</span></span>

<span><span style="color: var(--shiki-color-text)">}</span></span>
<span></span>
3. Enable PublishRecordEvents
settings
To ensure that a PutAway record is created through the trigger for every PurchaseOrder type record created, you'll need to enable PublishRecordEvents
in the settings.
<span><span style="color: var(--shiki-token-keyword)">package</span><span style="color: var(--shiki-color-text)"> transaction</span></span>
<span></span>
<span><span style="color: var(--shiki-token-keyword)">import</span><span style="color: var(--shiki-color-text)"> (</span></span>

<span><span style="color: var(--shiki-color-text)"> TypePermission: permissions.editorAccess</span></span>
<span><span style="color: var(--shiki-color-text)">}</span></span>
<span></span>
4. Apply the change using tailorctl
Run the following command to apply the changes.
<span><span style="color: var(--shiki-token-comment)"># Apply Executor</span></span>
<span><span style="color: var(--shiki-token-function)">tailorctl</span><span style="color: var(--shiki-color-text)"> </span><span style="color: var(--shiki-token-string)">workspace</span><span style="color: var(--shiki-color-text)"> </span><span style="color: var(--shiki-token-string)">apply</span><span style="color: var(--shiki-color-text)"> </span><span style="color: var(--shiki-token-string)">-m</span><span style="color: var(--shiki-color-text)"> </span><span style="color: var(--shiki-token-string)">./workspace.cue</span></span>
<span></span>
5. Verify the trigger
Click on the application and select Executors
from the navigation to view the created executor in the Console.
View the executor details by clicking the Open Details
button in the Details
column of the overview table.
In the console, select GraphQL Playground
to create a new sales order.
<span><span style="color: var(--shiki-token-keyword)">mutation</span><span style="color: var(--shiki-color-text)"> {</span></span>
<span><span style="color: var(--shiki-color-text)"> createSalesOrder(input:{ </span><span style="color: var(--shiki-token-string)">orderNumber</span><span style="color: var(--shiki-color-text)">: </span><span style="color: var(--shiki-token-constant)">987</span><span style="color: var(--shiki-color-text)"> }) {</span></span>
<span><span style="color: var(--shiki-color-text)"> id</span></span>
<span><span style="color: var(--shiki-color-text)"> }</span></span>
<span><span style="color: var(--shiki-color-text)">}</span></span>
<span></span>
After executing the query, view the job created for that executor by selecting the Jobs
tab and choosing the executor from the dropdown menu.
Clicking Open Attempts
displays details of job execution attempts made by the Executor. When the Target execution fails with a status code other than 2xx, the Tailor Platform retries the job execution. However, retries are not performed for certain errors, such as incorrect executor configuration or script errors.
Upon successful completion of the job, a new Shipment record is created.
