Vue.js Failed to resolve filter: key

转自：https://stackoverflow.com/questions/35835214/vue-js-failed-to-resolve-filter-key

I am following this tutorial https://laracasts.com/series/search-as-a-service/episodes/2 and got stuck on the following error

[Vue warn]: Invalid expression. Generated function body:  scope.keyup:scope.search
[Vue warn]: Failed to resolve filter: key

shown in console.

This is the code.

<input type="text" v-model="query" v-on="keyup: search | key 'enter'">
    <div class="results">
        <article v-for="movie in movies">
            <h2> @{{ movie.name  }}</h2>
            <h4> @{{ movie.rating  }}</h4>
        </article>
    </div>
</div>
    <script src="http://cdn.jsdelivr.net/algoliasearch/3/algoliasearch.min.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/vue/1.0.17/vue.js"></script>
    <script>
        new Vue ({
            el: 'body',
            data: { query: '' , movies: [] },
            ready: function (){
                this.client = algoliasearch('AH9XU5726U', '58fd00912ce725b3f627cfa6cb8292ee');
                this.index = this.client.initIndex('getstarted_actors');
            },
            methods: {
                search: function () {
                    this.index.search(this.query, function(error, results){
                        this.movies = results.hits;
                    }.bind(this));
                }
            }
        });
    </script>

Am I missing something? or is the tutorial outdated?

v-on="keyup: search | key 'enter'"

is a old version declaration, change to this:

v-on:keyup.enter="search"
