I'm getting the following error in one of my functions:

Is weird because everything works as it is supposed to.

Here's the relevant code to the error (the filename attribute causes it):

<button class="btn btn-success" 
        type="button" 
        ng-csv="filteredRecords" 
        filename="{{ createCsvFilename(dates, search) }}">
            Download {{filteredRecords.length}} results as CSV
</button>

And the function in question:

$scope.createCsvFilename = function(dates, search) {
    var startMoment = moment(dates.startDate);
    var endMoment = moment(dates.endDate);
    var filterCar = search.car;
    var filterDriver = search.driver;
    return startMoment.format('DD-MM-YYYY') + ' - ' + endMoment.format('DD-MM-YYYY') + ' - Car_' + filterCar  + ' - Driver_' + filterDriver + '.csv';
}

The search.car and search.driver are filter inputs that are undefined until the user fills them up.

Any idea about what might be causing the error?

• 2 Remove to passing "search" param. you can directly get it from your createCsvFilename method. $scope.search.car .. – Asik Commented Nov 7, 2014 at 11:06
• @Asik I did, I still get the same errors.. – Eric Mitjans Commented Nov 7, 2014 at 11:25
• Can you defined this scope in the first line of your controller...$scope.search={"car":"","driver":""} ..then try! – Asik Commented Nov 7, 2014 at 11:31
• This fixed the "3TypeError: Cannot read property 'car' of undefined", but not the interpolation error! Thanks anyway!!! – Eric Mitjans Commented Nov 7, 2014 at 11:43
• hmm..inform us if you fixed interpolation error..so that we all ware of it :) – Asik Commented Nov 7, 2014 at 11:48

Define the objects in your controller scope.

$scope.search={"car":"","driver":""} 
$scope.dates={"startDate":"","endDate":""}

And change your method as like below

$scope.createCsvFilename = function() {
    var startMoment = moment($scope.dates.startDate);
    var endMoment = moment($scope.dates.endDate);
    var filterCar = $scope.search.car;
    var filterDriver = $scope.search.driver;
    return startMoment.format('DD-MM-YYYY') + ' - ' + endMoment.format('DD-MM-YYYY') + ' - Car_' + filterCar  + ' - Driver_' + filterDriver + '.csv';
}

Also, remove params in calling a method

<button class="btn btn-success" 
        type="button" 
        ng-csv="filteredRecords" 
        filename="{{ createCsvFilename() }}">
            Download {{filteredRecords.length}} results as CSV
</button>
