custom widget: send command to node

elgarfo

@jkandasa your support is outstanding
your example works good and i can use it to build a dashboard to my needs. thank you very very much.

the reason it took me so long to respond is, that i needed to trace a startup error on my end:
[$injector:nomod] Module 'rzModule' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.

symptoms:

dashboard not loading correctly ({{ variable }} everywhere, nothing works)
angular throwing error about undefined module
testing with dev-console on firefox angular.module('rzModule'); yielded no error.
rzslider.js was actually loaded

cause:

firefox does not support <link rel="import">
the polyfill i pushed to github fb3d0d96 is working but:
too late.

so the polyfill for the import-feature is working, as i am able to load the rzModule after the dashboard html loaded completely and angular tried to load.
but it is not working fast enough.

i am currently trying to find a way to either delay angular startup until all imports are handled or to find a better way to include the /_configurations/additional-headers.html

current workaround: put <script src="https://cdnjs.cloudflare.com/ajax/libs/angularjs-slider/6.6.1/rzslider.js"></script> directly into index.html for firefox

EDIT:
html imports are also deprecated in chrome since v70 and will be removed with v73 which is only two versions from now (v71 as of this writing). see: chrome platform status

@elgarfo If we change anything in our current implementation, can fix the issue in both firefox and chrome? Any idea?

@elgarfo Thank you for the PR https://github.com/mycontroller-org/mycontroller/pull/486

How can I download the latest SNAPSHOT with this PR?
Is this it? Https: //travis-ci.org/mycontroller-org/mycontroller/builds/472109919

@jkandasa Thanx!
I checked this widget in Chrome and Firefox, it works great.

I'm just testing out various examples to understand how things work, I'm getting

Failed at: ${sId}  [in template "unknown" at line 1, column 69]

which I assume is from the first line of the html template, its not finding the angularjs custom controller ? I did modify app.js.

I'm pretty sure I've done all of the above to get the slider to appear on dashboard, but I must of missed something. I pasted the angularjs custom controller into the text field in HTML additional headers.

Any help thanks

@RMF69 To myself... the script binding id mistyped {sId:2}... got the camel case wrong. Slider is now visible but I get 400 error... as I don't have the variable set up correctly which will get updated ? I've created a global variable "sVariable" but I don't think this is right. How do I get the value out of the slider when its value changes ?

@RMF69 Ok looking through code, I understand that its updating a sensor.variabel and that this id is passed in via the script binding {sId:31}... 31 is the id of a sensor S_LIGHT_LEVEL![alt text]( Screenshot from 2019-12-28 13-05-08.png
I still get 400 bad requests... and

ERROR [Acme.Utils.ThreadPool(0)-PooledThread: Acme.Serve.Serve$ServeConnection@1415568e] [org.mycontroller.standalone.api.jaxrs.exception.mappers.ApplicationExceptionMapper:42] ApplicationException,
org.jboss.resteasy.spi.ApplicationException: java.lang.NullPointerException

I'd love to understand what I've done wrong:)

jkandasa

@RMF69 Can you report your MyController version? and if you modified the script please report your script.

RMF69

@jkandasa

Thanks, I've got the latest, Version 1.5.0. And I've not changed anything, just the script binding {sId:31} where 31 is the id of a light dimmer virtual sensor... see picture. I took the ID from the url of that page in the picture below.

jkandasa

@RMF69 Click on the Edit icon on the Level variable and use the id from the URL.

in version 1.5, you no need to hardcode rzModule on mycontroller/www/app.js. We have an option on UI to update angular modules.

RMF69

@jkandasa Thanks for confirming that in 1.5, the hardcoding of rzModule in mycontroller/www/app.js isn't required. However if I remove rzModule then the slider widget isn't displayed.

Still I can't get the example to work...I've got the id from the place you mention, mine is still 31... I've also noticed that the intial value of the sensor->variable isn't populated. I created simple script to update the value

var myImports = new JavaImporter(java.lang, java.util, org.mycontroller.standalone.utils.McUtils);

with(myImports) {
    dimSensor = mcApi.uidTag().getByUid("dimSensor").getResource();
    var v = dimSensor.value; //value2/3 etc
    dimSensor.setValue(parseInt(v) + 1);
    mcApi.sensor().sendPayload(dimSensor);
}

I insert the following code into "AngularJs custom controllers"

myControllerModule.controller('myCustomWidgetController', function($scope, SensorsFactory){
    $scope.sVariable = {
      id: null,
      value:null
    };
  
    $scope.loadVariable = function(){
      SensorsFactory.getVariable({id:$scope.sVariable.id}, function(response){
        if(response.value != undefined){
          $scope.sVariable.value = parseInt(response.value);
        } 
      });
    }

    $scope.slider = {
      options: {
        floor: 0,
        ceil: 100,
        step: 1,
        minLimit: 0,
        maxLimit: 90,
        onEnd: function() {
            $scope.sendPayload($scope.sVariable);
        },
      }
  };

    // send payload
    $scope.sendPayload = function(sVariable){
      SensorsFactory.updateVariable(sVariable, function(){
        //update Success
      },function(error){
        displayRestError.display(error);
      });
    };
  });

Which is just the original example above, no changes... it seems to me that the pointer/reference to the variable I want to have connected to the slider is correct or working, both when the value is initialized on the loadVariable and when updated. But I just can't see what I've done wrong.

jkandasa

@RMF69 Do you see any error on the browser console and/or in MyController log file?

RMF69

@jkandasa Sorry... I thought I'd edited or deleted that reply saying it didn't work. It now works... I'd taken the sensor ID from the summary page and not the edit page as you pointed me to in your last reply.

So its working now... my mistake, thanks for your patience.
