Getting additional Data from separate Table

[LorindaGilbert]

Hi All,

Think I'm just completely overlooking something here.  I'm attempting to get the closest street to a point for an address and gathering the individual components of the name for the address point.

Here's what I'm attempting to use for the code.  It was telling me that I needed another curly brace, checked them all, they all matched up.  Now it says that the else is a reserved word on the second else on line 37.  Any help is appreciated.

var fsn = $feature.FullStreetName;
var streetLayer = FeatureSetByName($datastore, "server.dbo.StreetCenterline");
var pre = $feature.PreDirection;
var sn = $feature.StreetName;
var st = $feature.StreetType;
var post = $feature.PostDirection;
var searchDistance = 150;
var streetIntersect = Intersects(streetLayer, Buffer($feature, searchDistance, "feet"));
var cnt = Count(streetIntersect);
var minDistance = Infinity;

if (cnt > 0) {
    for (var street in streetIntersect) {
        var dist = Distance(street, $feature, "feet");
        if (dist < minDistance) {
            var stparse = {
                attributes: {
                pre: ["streetLayer.PreDirection"],
                sn: ["streetLayer.StreetName"],
                st:  ["streetLayer.StreetType"],
                post: ["streetLayer.PostDirection"],
                fsn:  ["streetLayer.FullStreetName"],
                minDistance: dist
                }
            }
        } else {
            var stparse = {
                attributes: {
                pre: "",
                sn: "",
                st:  "",
                post: "",
                fsn:  ""
                }
            }
        }    
    } else {
    // pass no features found within search distance, name remains null
        var stparse = {
          attributes: {
            pre: "",
            sn: "",
            st:  "",
            post: "",
            fsn:  ""
          }
      }
    }
}

return stparse;

You didn't close out the for loop before the else on line 37

Try this:

var fsn = $feature.FullStreetName;
var streetLayer = FeatureSetByName($datastore, "server.dbo.StreetCenterline");
var pre = $feature.PreDirection;
var sn = $feature.StreetName;
var st = $feature.StreetType;
var post = $feature.PostDirection;
var searchDistance = 150;
var streetIntersect = Intersects(streetLayer, Buffer($feature, searchDistance, "feet"));
var cnt = Count(streetIntersect);
var minDistance = Infinity;

if (cnt > 0) {
  for (var street in streetIntersect) {
    var dist = Distance(street, $feature, "feet");
    if (dist < minDistance) {
      var stparse = {
        attributes: {
          pre: ["streetLayer.PreDirection"],
          sn: ["streetLayer.StreetName"],
          st:  ["streetLayer.StreetType"],
          post: ["streetLayer.PostDirection"],
          fsn:  ["streetLayer.FullStreetName"],
          minDistance: dist
        }
      }
    } else {
      var stparse = {
        attributes: {
          pre: "",
          sn: "",
          st:  "",
          post: "",
          fsn:  ""
        }
      }
    }    
  }
} else {
  // pass no features found within search distance, name remains null
  var stparse = {
    attributes: {
      pre: "",
      sn: "",
      st:  "",
      post: "",
      fsn:  ""
    }
  }
}

return stparse;

That allowed it to valid, however, now it is complaining about "Undefined keyword is used in the dictionary return script. [attributes]" when I try to insert a new record.  I've checked my column names from the StreetCenterline feature class - they are all spelled correctly.  I did remove the 'minDistance:  dist' line as that is not in the feature class that I'm adding data to.

I have tested the base part of this script with just one column being filled in and it worked.  It seems to be the use of 'attributes: {list....} that is tripping me up.  I am using the same column names in both my address point and street centerline feature classes.  Would I be needing the "result" term in there at all?

Thanks,

Lorinda

Sorry, I did not read that post correctly and typed too soon.

I recently had the same problem. Arcade doesn't super like nested dictionaries the way we would do them in Python.

var dDict ={}
var t = "red"
var s = "apple"
var u = "delicious"
dDict[t] = {s : u}
return dDict

//Yields : {"red": {s:"delicious"}}

BUT this works instead.

var dDict ={}
var t = "red"
var s = "apple"
var u = "delicious"
dDict[t] = Dictionary(s, u)
return dDict

//Yields : {"red": {"apple":"delicious"}}

Try manually constructing the dictionary like that and see what you get.
