Hello All,

 

I'm using Web App Builder 2.2 Developer Edition.

 

Once feature is captured using Edit Widget, I want to apply attributes from the spatial query before apply edits. I have written my code as below to achieve this but query gets completed after attribute inspector is opened.

 

_canDeleteSelectionFeatures: function () {
// return ture if all features can be deleted,
// else return false.
var canDeleteFeatures = true;
var selectionFeatures = this._getSelectionFeatuers();
if(selectionFeatures.length === 0) {
canDeleteFeatures = false;
} else {
array.some(selectionFeatures, function (feature) {

var featureLayer = feature.getLayer && feature.getLayer();

 

//I have written below line 
on(featureLayer, 'before-apply-edits', lang.hitch(this, this.onBeforeApplyEdits))

if (!featureLayer ||
!featureLayer.getEditCapabilities({ feature: feature }).canDelete
) {
canDeleteFeatures = false;
return true;
}

}, this);
}
return canDeleteFeatures;
},

 

and then onBeforeApplyEdits, I have done spatial query to get the required attribute as below:

 

onBeforeApplyEdits: function (evt) {

if (evt.adds != null) {

 

var selectionFeatures = this._getSelectionFeatuers();

array.some(selectionFeatures, lang.hitch(this,function (feature) {

var queryDivsionName = new Query();
queryDivsionName.returnGeometry = false;
queryDivsionName.outFields = ["division"];
queryDivsionName.geometry = feature.geometry;
queryDivsionName.spatialRelationship = Query.SPATIAL_REL_INTERSECTS;

var queryDivsionNameTask = new QueryTask(divsionLayer.url);

execute(queryDivsionName, lang.hitch(this, function (featureSet) {
console.log(featureSet);
divisionName = featureSet.features[0].attributes.division;
}));
}));

 


evt.adds[0].attributes.division = divisionName ;
}

 

Please suggest how to spatial query for attribute and apply to feature before apply edits.

 

Regards,

Krish
