ION Actions is a powerful tool that allows users to create, write, update, and delete rules governing the behavior of your manufacturing processes using GraphQL.
It helps you accomplish everything laid out below but with a in line code editor and streamline UI.
1. Introduction
Control workflows (e.g. when users can progress status), set conditions for data validation (e.g. require fields).
2. Turn rules on in your environment
First, rules must be enabled in your organization settings in order to use them.
Check that the rules are enabled with the below query:
{ me { organization { id _etag settings { rules { enabled } } } }}
If they are not, enable them with this mutation:
With the following input variables (retrieve the etag from the first query):
3. Definition of ION Action Attributes
Here are the definitions of key ION Action attributes:
Title: The title is a visual identifier for the ION Action, shown in toast notifications, and used for internal tracking and logging. It should briefly describe the purpose of the ION Action.
Context: The context is a placeholder that contains the data used in the ION Action's code. It can include model attributes, user roles, issue details, or any other relevant data. It is represented as a JSON string in GraphQL input. An example of a context structure could be:
Code: The code attribute contains the Python-based script that is executed when the ION Action is triggered. It specifies the conditions and actions of the ION Action. If the conditions are not met, a ValidationError is raised.
ErrorState: All active rules will BLOCK the action from occurring if the rule conditions are met. The errorState is a deprecated feature for now, so "ALLOW" or "BLOCK" as an error state are both going to BLOCK the action upon execution of the rule.
4. Creating an ION Action with GraphQL
Create an ION Action
Variables:
5. Updating an ION Action with GraphQL
Find the rule you seek to update You'll need the rule's id and _etag value for the next step
Query all rules
Write the UpdateRule Mutation:
Write a mutation using the UpdateRule input type, specifying the rule's id, _etag and the updates you seek to make (generally the context, code, or enabled values).
Query variables:
Execute the Mutation: Run the mutation in the GraphQL Explorer to update the ION Action.
NOTE: Every time you update a rule, its _etag value will change, so you need to start from step 1 each time you update a rule.

6. Deleting an ION Action with GraphQL
This isn't necessary as you can set enabled to "false", but to delete an existing ION Action:
mutation CreateRule($create_rule: CreateRuleInput!) {
createRule(input: $create_rule) {
rule {
id
enabled
status
title
target
eventType
context
code
errorState
_etag
}
}
}
{
"create_rule": {
"enabled": true,
"title": "This is the message that shows in the toast banner",
"target": "ISSUE",
"eventType": "UPDATE",
"ruleType": "VALIDATION",
"errorState": "ALLOW",
"context": "specify the fields for the code to interpret",
"code": "the python code which runs the logic - must be a single line! (chatGPT helps a lot here)"
}
}
{
rules{
edges{
node{
id
_etag
title
ruleType
eventType
target
code
context
enabled
}
}
}
}
mutation UpdateRule($update_rule: UpdateRuleInput!) {
updateRule(input: $update_rule) {
rule {
id
_etag
enabled
title
context
code
}
}
}
{
"update_rule": {
"id": from step 1,
"etag": "copied from the step 1",
"enabled": "true or false"
"title": "You could modify the title here, or remove this line",
"context": "overwrite the query, or remove this line",
"code": "completely overwrite the code, or remove this line"
}
}
