marionette - Backbone.marionette 重新渲染模型更改 View

Question

//当我点击 kickassessor 按钮时，它会更新数据库，但 View 不会更新。这是我的代码。 返回 Marionette.ItemView.extend( {

    initialize : function ( options ) {
        var self = this;

        _.bindAll( this );

        _.each( options, function ( value, key ) {
            self[ key ] = value;
        } );
        //this.model.on('change', this.render, this);

        return this;
    },


    // Ui events hash
    events : {
        'mouseover a.btn'  : 'showTooltip',
        'click #kickBtn'   : 'kickAssessor',
        'click #deleteBtn' : 'deleteUser'
    },

    // on render callback
    onRender : function() {
        this.ui.kickBtn.tooltip( {
            title : 'Kick as assessor'
        } );

        this.ui.deleteBtn.tooltip( {
            title : 'Delete user'
        } );
    },

    kickAssessor : function ( ) {
        this.model.save({role:'2'});
                    //on success it should update the itemview
    },

Answer 1

您可以添加一个 modelEvents 散列 (https://github.com/marionettejs/backbone.marionette/blob/master/docs/marionette.itemview.md#modelevents-and-collectionevents):

modelEvents: {
  "sync": "render"
}

每次您的模型与服务器同步时，上面的代码都会调用render函数。
