javascript - Angular filter a object by its properties

I have an object with a series of object properties that is in the following similar structure (which is the way the data is coming back from a service):

{
  "1": {
    "type": "foo",
    "name": "blah"
  },
  "2": {
    "type": "bar"
  },
  "3": {
    "type": "foo"
  },
  "4": {
    "type": "baz"
  },
  "5": {
    "type": "test"
  }
}

When I do a ng-repeat, I can iterate over all 5 of these object, something like:

<div ng-repeat="item in items">{{item.type}}</div>

However, what I really want to do is iterate only over those items that are NOT the type "foo", namely 3 iterations instead of 5. I know that filters can somehow be leveraged to do this, but I am not sure how. I tried the following:

<div ng-repeat="item in items| !filter:{type:'foo'}">{{item.type}}</div>

but this doesn't work. In fact, even doing the following to limit to just 2 objects(those with item.type==="foo"), it doesn't work and does 5 iterations:

<div ng-repeat="item in items| filter:{type:'foo'}">{{item.type}}</div>

In essence, I want to do something similar to:

<div ng-repeat="item in items" ng-if="item.type !=='foo'>{{item.type}}</div>

However, I know that one doesn't work.

Little late to answer, but this might help :

If you want to filter on a grandchild (or deeper) of the given object, you can continue to build out your object hierarchy. For example, if you want to filter on 'thing.properties.title', you can do the following:

<div ng-repeat="thing in things | filter: { properties: { title: title_filter } }">

You can also filter on multiple properties of an object just by adding them to your filter object:

<div ng-repeat="thing in things | filter: { properties: { title: title_filter, id: id_filter } }">

The syntax of 'not equals' is just a little off, try the following:

<div ng-repeat="thing in things | filter: { properties: { title: '!' + title_filter } }">
