I have a list of items that I'm displaying with ng-repeat
. I want to add a filter to show/hide archived items.
I have added a checkbox:
<input type="checkbox" ng-model="queryFilter.archived">Show archived messages
In my controller I have this:
$scope.queryFilter = {
archived: false
};
My list of items is displayed in a table. I've tried the following:
<tr ng-repeat="message in messages | filter : queryFilter">
<tr ng-repeat="message in messages | filter : { archived: queryFilter.archived }">
<tr ng-repeat="message in messages | filter : queryFilter track by $index">
I get this error:
Error: [filter:notarray]
Expected array but received: {}
The filtering does work but I want to know why I am getting the error.
Your messages
must be containing the data in Object
form not in the Array
form.
That is why this error is being thrown. Check the doc https://docs.angularjs.org/error/filter/notarray
From the docs:
Filter must be used with an array so a subset of items can be returned. The array can be initialized asynchronously and therefore null or undefined won't throw this error.
So make sure, your $scope.messages
containing data in array form not in the Object form.
