在我简单的主干应用程序中,我试图更新一个模型,并且每次它发送一个放置请求而不是发布。
好吧,这是我的模型,名为categoryModel
define(['Backbone'], function (Backbone) {
var CategoryModel = Backbone.Model.extend({
defaults: {
ID: '',
Name: 'Empty',
TagID: '0',
GID: '0'
},
idAttribute: "ID",
initialize: function () {
if (!this.get('Name')) {
this.set({ 'Name': this.defaults.Name });
}
}
});
return CategoryModel;
});
这是收藏
define(['Backbone','../../models/categories/categoryModel'], function (Backbone, categoryModel) {
var CategoryCollection = Backbone.Collection.extend({
url: '/parentcategory/Actions',
model: categoryModel
});
return new CategoryCollection;
});
这是我在视图中的方法
在一个keychange event
createNewItem: function (e) {
var $this = $(e.currentTarget);
$('#selectedCategoryName').html($this.val());
//it creates a new model
globals.NewCategory = new CategoryModel({ Name: $this.val() });
}
在handleDrop event
handleDropEvent: function (event, ui) {
var draggable = ui.draggable;
//check if name has set
if (!globals.NewCategory) {
alert("Please write a category name");
$('#createNewCategory').focus();
return;
}
//get itemID
var itemID = draggable.attr("id").split('_')[1];
var itemDesc = draggable.attr("id").split('_')[0];
//check items category
if (itemDesc == "Tag") {
//check if tagID already exists
if (globals.NewCategory.TagID) {
alert("you have already specify a tag from this category");
return;
}
globals.NewCategory.set("TagID", itemID);
} else if (itemDesc == "gTag") {
if (globals.NewCategory.GID) {
alert("you have already specify a tag from this category");
return;
}
globals.NewCategory.set("GID", itemID);
}
categoriesCollection.create(globals.NewCategory, {
silent: true,
wait: true,
success: function (model, response) {
model.set("ID", response);
alert(model.id);
}
});
}
categoriesCollection.create被调用两次。首先用于设置 TagID(在成功请求时它会获得一个 ID),其次用于设置 GID。由于 ID 已设置,不应该在第二次调用时发送 POST 请求而不是 PUT 吗?
我究竟做错了什么?
谢谢
