私はカレンダースタイルのバックボーンアプリに取り組んでいますが、かなり新しいです。私はこれに12時間以上取り組んできましたが、それでもテンプレートにJSONデータを入力させることができませんでした。

これが私が今日書いたいくつかのコードです：

モデル

var CalendarDay = Backbone.Model.extend({
    defaults: function () {
        return {
            title: "No days for this event",
            done: false
        };
    },
    initialize: function () {}
});

var calendarItem = new CalendarDay({
    urlRoot: URL
});

コレクション

var Calendar = Backbone.Collection.extend({
    model: CalendarDay,
    url: URL
});

意見

var CalendarView = Backbone.View.extend({
    template: _.template($('#days').html()),
    initialize: function () {
        this.collection = new Calendar();
        this.collection.fetch();
        this.collection.bind("reset", this.render, this);
        this.loadTimes();
    },
    render: function () {
        var JSON = this.collection.toJSON();
        this.$el.html(this.template(JSON));
        console.log(JSON);
    },
    listDays: function () {

    }

});

var calendarView = new CalendarView({
    model: calendarItem
});

サーバーから取得したJSONは次のとおりです。

0: Object
activity_logs: Array[0]
attendee_code: "BBNVKBGT"
attendee_fee: "0"
cego_fee: "0"
certificate_fee: "0"
created_at: "2013-02-13 11:29:03"
days: Array[1]
description: "A wonderful serenity has taken possession of my entire soul, like these sweet mornings of spring which I enjoy with my whole heart. I am alone, and feel the charm of existence in this spot, which was created for the bliss of souls like mine."
disciplines: Array[3]
done: false
fee_transaction_id: "0"
id: "102"
marketing_materials: Array[0]
messages: Array[0]
name: "My very first event"
organization_id: "1"
start_at: "2013-02-28 00:00:00"
state_id: "38"
states: Array[2]
title: "No days for this event"
updated_at: "2013-02-13 11:29:04"
venue_id: "55"

（console.logから）添付されているのは、JSONを使用したコンソールログのより良いビューです。 JSONのスクリーンショット

更新：これが私の文字列化されたJSONです：

これが私のテンプレートビューです：

    <script id="days" type="text/template">
            <a class="btn small-btn marginRight"></a>
    </script>

ここに追加しようと思ったのですが、上記のようなテンプレートタグを使用すると<% title %>、エラーが発生しますUncaught ReferenceError: title is not defined

私は疲れ果てており、自分自身に背骨を教えることは想像以上に難しいです。このボールを再び転がすための助けは素晴らしいでしょうありがとう。

ビューを変更

this.$el.html(this.template(JSON));

に

this.$el.html(this.template({days: JSON}));

テンプレートを変更する

<script id="days" type="text/template">
    <% _.each(days, function(day) { %> <a class="btn small-btn marginRight"><%= day.title %></a> <% }); %>
</script>
