Cannot retrieve the ng-grid value from JSON object in AngularJS

Question

this is the JSON object i got from two table joining..

[{"a.opp_name" : "fff",
  "b.client_name" : "Burlington Pension",
  "a.opp_value" : "2.0",
  "a.opp_target_date" : "2014-08-08",
  "d.parameter_name" : "WON",
  "a.opp_rm" : "Lisa Hayden",
  "a.opp_probability" : "43",
  "c.parameter_name" : "Fixed Income",
  "a.opp_next_step" : ""}]

and this is the Javascript file.

$scope.gridOptions = {      
        data : 'Values',
        selectedItems: $scope.mySelections,
        multiSelect: false,
        columnDefs: [
          {field:'opp_key', displayName:'Opportunity Key',visible:false},
          {field:'opp_name', displayName:'Name', cellTemplate: '<div>{{a.opp_name[0]}}</div>'},
          {field:'b.client_name', displayName:'Client' },
          {field:'a.opp_value', displayName:'Target Amount' },
     // ,  cellTemplate:'<div>${{row.entity.opp_probability}}M <div>'    | date : MM-dd-yy
          {field:'a.opp_target_date', displayName:'Target Date'},
          {field: 'd.parameter_name',displayName:'Stage'},
          {field:'a.opp_rm', displayName:'Owner'},
          {field:'a.opp_probability', displayName:'Probability', },
          // cellTemplate:'<div><progress id="progressBar" data-ng-model="row.entity.opp_probability" data-ng-value="row.entity.opp_probability=convert(row.entity.opp_probability)" max="100" style="width: 50px;"></progress>&nbsp; {{row.entity.opp_probability}}%</div>'
          {field:'c.parameter_name', displayName:'Mandate'}, 
          {field:'a.opp_next_step', displayName:'Next Step'}]
};

From here we didn't get the values in ng-grid..

Answer 1

For this issue we use the Surrogate names for the same keyname..here parameter name coming two times.so we can use the surrogate name for differentiating the two parameter names.

Like this..

ColumnNames ="opp_key,opp_name,client_name,opp_value,opp_target_date,parameter_name,opp_rm,opp_probability,parameter_name,opp_next_step,user_first_name";

SurrogateNames ="opp_key,opp_name,client_name,opp_value,opp_target_date,stage,opp_rm,opp_probability,mandate,opp_next_step,user_first_name";
