trying to troubleshoot the hard-coded bug in https://github.com/mozilla/redash/pull/94/files

get-data-source-version.js

function GetDataSourceVersionCtrl(Events, toastr, $scope, DataSource) {
  // 'ngInject';

  // this works but hard codes the data source id
  this.getDataSourceVersion = DataSource.version({ id: 6 });

  // this doesn't event lint (unexpected block) for some reason but also doesn't work
  this.getDSV = (variable) => {
    return DataSource.version({ id: variable});
  };

  // this doesn't work
  function getSQLVersion(ida) {
    return DataSource.version({ id: ida }).message;
  }

  // this doesn't work
  this.thisOne = getSQLVersion(6);

  // this doesn't work
  this.showMeTheThing = document.getElementById('data-source-selection').value;
}

const GetDataSourceVersionInfo = {
  bindings: {
    schema: '<',
    onRefresh: '&',
    datasourceid: '=',
  },
  controller: GetDataSourceVersionCtrl,
  template: '<span>{{ $ctrl.getDSV($ctrl.datasourceid).message }}</span>-{{ $ctrl.showMeTheThing }}-{{ $ctrl.datasourceid }}-<span ng-bind="$ctrl.getSQLVersion($ctrl.datasourceid)"></span>',
};

export default function (ngModule) {
  ngModule.component('getDataSourceVersion', GetDataSourceVersionInfo);
}
