java - Groovy Scripting with elasticsearch -


my groovy script code:

def value=dynamicvalue      def nvalue=newvalue def field=fieldvalue def prod  newvalue=newvalue.tointeger() prod=doc[''+dynamicvalue+''].value*newvalue          if(._source.doc[''+fieldvalue+''].value != null) {     ._source.doc[''+fieldvalue+''].value=prod }

i trying update value of field in elasticsearch index like

._source.doc[''+fieldvalue+''].value=prod

where avg_price_per_unit field in index.

but when exceuting java 

  "reason" : {             "type" : "script_exception",             "reason" : "failed run file script [fieldscript] using lang [groovy]",             "caused_by" : {               "type" : "illegal_argument_exception",               "reason" : "argument type mismatch"             }  there solution??

my java code:

map<string, object> params = immutablemap.of("dynamicvalue",aggregatevalue_first, "newvalue", aggregatevalue_second, "fieldvalue",hash);  try {      searchresponse se = client.preparesearch(indexname)          .addscriptfield("checkvalue", new script("fieldscript", scripttype.file, "groovy", params))         .execute().actionget();          system.out.println(se.tostring());  } catch(runtimeexception e) {      e.printstacktrace();  }

my log shows 

      if (._source.doc[''+fieldvalue+''] != null) {_source.doc[''+fieldvalue+''].value=prod}      ^

you have typo in script, change this:

def value=dynamicvalue      def nvalue=newvalue def field=fieldvalue def prod  newvalue=newvalue.tointeger() prod=ctx._source[dynamicvalue].value * newvalue          if(ctx._source[fieldvalue].value != null) {     ctx._source[fieldvalue].value=prod }

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
