Constraint Rule to Prevent Deleting of Features

ChrisGAEG

Hello, I am trying to write a rule that will prevent the deletion of features in an fc. I'm getting the error 'Invalid expression. Close parenthesis expected' but I don't know why. Here is what I have so far.

var currentAssetId = $feature.cab_id
var fsMyClass = FeatureSetByName($datastore, "Proposed_OLT_LCP_Boundaries_copy")
var fsResult = filter(fsMyClass, "cab_id = @currentAssetId")

if (first(fsResult) IN $originalfeature.cab_id)

return true;
else
return false;

I believe the problem is in the if statement but I don't know what would be wrong here.

The if statement is an invalid syntax. You are comparing a feature (first(fsResult)) to a value $originalfeature.cab_id. Plus don't use IN, use == instead and compare the actual values

That being said, I'm not sure what the rule is trying to do, maybe provide a brief description of what the rule is suppose to do? Going by your statement if you want to prevent deletion of features it is a matter of simply creating a constraint rule that returns false.

return false;

I tried this while troubleshooting before posting, but unfortunately this doesn't clear the error. Thanks for taking a look.

Just a shot in the dark, but don't you need to enclose things in curly braces?

if (first(fsResult) IN $originalfeature.cab_id){
    return true;
}else{
    return false; 
}
