store.filter()不像预期的那样工作ember.js(试图搜索模型)

store.filter() not working as expected ember.js (Trying to search models)

本文关键字：ember 工作 js 图搜索 模型 filter store      更新时间：2023-09-26

我正试图实现一个搜索系统在这里，我有一些麻烦与store.filter()

首先，除了这里，我找不到任何关于store.filter()方法的好的文档:http://emberjs.com/guides/models/frequently-asked-questions/

所以我使用该页提供的示例作为指导。

这是我的代码

App.ApplicationController = Ember.ObjectController.extend({
    isDropdown: false,
    actions: {
        handle_search: function() {
            var search_text = this.get('search_text');
            if (search_text) {
                this.set('isDropdown', true);
                return this.store.filter('procedure', {proc_name: search_text}, function(procedure) {
                    console.log(procedure);
                });
            }
        }
    }
});

但是当我记录返回的东西时，它返回的基本上是每一个模型。而不是没有结果或只有有限的结果

在procedure之上，它自己不是模型的对象，它是其他的东西。

所以我的问题是如何获得具有字段的实际模型，以及如何确保存储实际上正在过滤结果?

您只需要传入一个函数，该函数为包含记录

返回true/false
App.IndexRoute = Ember.Route.extend({
  model: function() {
    return this.store.filter('color', function(item){
      return item.get('color')=='red';
    });
  }
});

如果您想在包含可选查询参数的同时(通过查询查找)回调服务器，下面的示例将调用/colors?color=green 

App.IndexRoute = Ember.Route.extend({
  model: function() {
    return this.store.filter('color', {color:'green'}, function(item){
      return item.get('color')=='red';
    });
  }
});
/**
    Takes a type and filter function, and returns a live RecordArray that
    remains up to date as new records are loaded into the store or created
    locally.
    The callback function takes a materialized record, and returns true
    if the record should be included in the filter and false if it should
    not.
    The filter function is called once on all records for the type when
    it is created, and then once on each newly loaded or created record.
    If any of a record's properties change, or if it changes state, the
    filter function will be invoked again to determine whether it should
    still be in the array.
    Optionally you can pass a query which will be triggered at first. The
    results returned by the server could then appear in the filter if they
    match the filter function.
    Example
    ```javascript
    store.filter('post', {unread: true}, function(post) {
      return post.get('unread');
    }).then(function(unreadPosts) {
      unreadPosts.get('length'); // 5
      var unreadPost = unreadPosts.objectAt(0);
      unreadPost.set('unread', false);
      unreadPosts.get('length'); // 4
    });
    ```
    @method filter
    @param {String or subclass of DS.Model} type
    @param {Object} query optional query
    @param {Function} filter
    @return {DS.PromiseArray}
  */
