我有以下代码,它应该在我的模型中获取一个对象并使用模板呈现它:
productDetails: function (id) {
var product = new app.models.Product({id: id});
product.fetch({
success: function (data) {
console.log(data);
app.slider.slidePage(new app.views.ProductView({model: data}).render().$el);
}
});
}
但是,出于某种原因,data
是我所有模型对象的列表:
attributes: Object
0: Object
1: Object
2: Object
3: Object
4: Object
5: Object
6: Object
7: Object
8: Object
9: Object
10: Object
11: Object
12: Object
13: Object
...
id: "73"
我是Backbone的新手,所以我不知道是什么原因造成的......
您需要更多代码吗?
ProductModel.js
app.models.Product = Backbone.Model.extend({
initialize: function () {
},
sync: function (method, model, options) {
if (method === "read") {
app.adapters.product.findById(parseInt(this.id)).done(function (data) {
options.success(data);
});
}
}
});
app.models.ProductCollection = Backbone.Collection.extend({
model: app.models.Product,
sync: function (method, model, options) {
if (method === "read") {
app.adapters.product.findByName(options.data.name).done(function (data) {
options.success(data);
});
}
}
});
答案 0 :(得分:1)
您的adapters.product
可能是指该集合,然后在您的产品sync
函数中返回该集合。
解决方案是这样的:
var findById = function (id) {
var deferred = $.Deferred();
var product = null;
var l = products.length;
for (var i = 0; i < l; i++) {
if (products[i].id === id) {
product = products[i];
break;
}
}
deferred.resolve(product); // HERE WAS product__s__
return deferred.promise();
}
