Problems trying to implement attribute rule example in Pro documentation
Aha this is a little bit tricky. I will attempt to write the basic version of this but there are so many edge cases that this script doesn't solve. (Moving feature, deleting a bunch of features at once) .. But this is just a start..
Two classes
polygonClass
pointClass
On the pointClass add an attribute rule on insert
//on insert
//check if we are intersecting a polygon. If yes, set the hasPoint field on the polygon to Yes
var fsPolygon = FeatureSetByName($datastore, "polygonClass", ["globalId"], false);
var intersectedPolygons = Intersects (fsPolygon, $feature);
var polygonFeature = null;
for (polygonFeature in intersectedPolygons) break;
if (polygonFeature == null) return $feature.field; // no polygon intersected found , quit..
//we found a polygon feature set its HasPoint to Yes
return {
"result": $feature.field,
"edit": [
{
"className" : "polygonClass",
"updates": [
{
"globalId": polygonFeature.globalId,
"attributes": {"hasPoint": "yes" }
}
]
}
]
}On the pointClass add another attribute rule on Delete
//on delete
//check if we are intersecting a polygon. If yes, make sure we are the last point, if yes set hasPoint to No!
var fsPolygon = FeatureSetByName($datastore, "polygonClass", ["globalId"], true);
var intersectedPolygons = Intersects (fsPolygon, $feature);
var polygonFeature = null;
for (polygonFeature in intersectedPolygons) break;
if (polygonFeature == null) return $feature.field; // no polygon intersected found , quit..
//query the pointClass
var pointGlobalId = $feature.globalid;
var fsPoint = FeatureSetByName($datastore, "pointClass", ["globalId"], false);
var intersectedPoints = Filter(Intersects (fsPoint, Geometry(polygonFeature)), "globalId <> @pointGlobalId"); // find all points that are not me in the polygon
//there are still few points, quit!
if (Count(intersectedPoints) > 0) return $feature.field
//$feature was the last point, .. set hasPoint to No
//we found a polygon feature set its HasPoint to Yes
return {
"result": $feature.field,
"edit": [
{
"className" : "polygonClass",
"updates": [
{
"globalId": polygonFeature.globalId,
"attributes": {"hasPoint": "no" }
}
]
}
]
}
Close, but running into a problem here.
This is my implementation.
var fsBuffer = FeatureSetByName($datastore, "Section3.DBO.PlannedSoilsSamplngLocationBuffers", ["GlobalID"], false);
var intersectPolys = Intersects(fsBuffer, $feature);
var fsBufferFeature = null;
for (fsBufferFeature in intersectPolys) break;
if (fsBufferFeature == null) return $feature.GlobalID;
//we found a polygon feature set its HasPoint to Yes
return {
"result": $feature.GlobalID,
"edit": [
{
"className" : "Section3.DBO.PlannedSoilsSamplingLocationsBuffers",
"updates": [
{
"GlobalID": fsBufferFeature.GlobalID,
"attributes": {"SampleComplete": "Yes"}
}
]
}
]
}
and this is the error I get:
I think I am mis-interpreting your $feature.field syntax. What field in the point feature class should this rule be attached to? It looks like the only field available is SampleID (the one that is auto-calculated from the previous rule).
BTW, how do you insert that nice code block into the posts?
