Rule returning multiple events

[jgoux]

Hello,

thanks for this great lib! 👍

Is there a reason why the rule can't return multiple events when it succeed ?

@jgoux thanks, you're welcome!

No reason I can think of off the top of my head. Perhaps we'll look at adding this in a future release if there's enough demand.

In the meantime, you may be able to work around this by listing multiple events in the params:

let rule = {
  conditions: {
   /* ... */
  },
  event: {
    type: 'multiple-events',
    params: {
      event1: {
        /* any additional event 1 parameters */
      },
      event2: {
        /* any additional event 2 parameters */
      }
    }
  }
}

You would of course need to write a few lines of logic for handling the 'multiple-events' payload

[jgoux]

Indeed, it works well that way too. 👍 (I pass an array as the params)

event: {
    type: 'SUCCESS',
    params: [
      {
        type: 'INDUIRE_RESULTAT',
        params: {
          analyse: 'URFIN',
          resultat: 'F'
        }
      },
      {
        type: 'INDUIRE_RESULTAT',
        params: {
          analyse: 'FOO',
          resultat: 'BAZ'
        }
      }
    ]
  }

I can live with it for now, thanks for the tip @CacheControl :D

Going to close this out as it doesn't seem to be gaining much traction, and the workaround has been reported to be successful.

Hi @CacheControl , not sure if this is obsolete, but we at riskine would definitely love the feature discussed here. Cheers, Johannes

Would greatly appreciate multi-event capability as well.

Just a note, that the workaround proposed here would be incompatible with some new functionality that relies on the correct use of the params for a single event, e.g. Support Facts in Events.

[chris-pardy]

@honzabit This should still work, you just won't get the new feature.
I'm reopening this issue and putting it into a version 7 wish list since it's going to need to be a breaking change.

@chris-pardy - do we have something like pairing of conditions and events e.g condition 1 is successful, return event 1, condition 2 is successful, return event 2.
Probably we are trying to implement something similar to Drools, which can process excel sheet as a set of separate conditions and separate output.
[
{
"Facts": {
"name": "Kashif"
}
},
{
"Condition": {
"any": [
{
"fact": "name",
"operator": "equal",
"value": "Kashif"
}
]
},
"Event": {
"Result": {
"Message": "Facts equal to Kashif"
}
}
},
{
"Condition": {
"any": [
{
"fact": "name",
"operator": "notEqual",
"value": "Kashif"
}
]
},
"Event": {
"Result": {
"Message": "Name not equal to Kashif"
}
}
}
]

Is this becoming implemented ?

[brandoningli]

Any updates here? This would be extremely useful in a current use case. I'm currently having to create custom events that are combinations of other events in order to accommodate.
