如何在路由之间传递选定的值?

[英]How to pass selected value between routes?

I am quite new to the EmberJS.我对 EmberJS 很陌生。

This is my model: book.js这是我的模型: book.js

import DS from 'ember-data';

export default DS.Model.extend({
    title: DS.attr('string'),
    author: DS.attr('string'),
    picture: DS.attr('string'),
    buyer: DS.attr('string'),
    bought: DS.attr('boolean', { defaultValue: false }),
    createdAt: DS.attr('date', { defaultValue() { return new Date(); } })
});

I have the following route: Books.js我有以下路线: Books.js

import Ember from 'ember';

export default Ember.Route.extend({
    model: function(){
        return this.store.findAll('book');
    }   
});

and a bit from corresponding books.hbs和一些来自相应的books.hbs

{{#each model as |book|}}
        <div class="book-container col-xs-12 col-sm-6 col-md-4">
            <div class="card">
                <div class="wrapper">
                    <div class="details col-md-12">
                        <h3 class="product-title">Title {{book.title}}</h3>
                        <p class="product-description">Author:{{book.author}}</p>
                        {{#link-to 'books.give' }} Buy {{/link-to}}
                    </div>
                </div>
            </div>
        </div>
{{/each}}

This code returns all the books that I currently store in the app.此代码返回我当前存储在应用程序中的所有书籍。

The idea is to get selected Book object from books.hbs and display it in give.hbs .这个想法是从books.hbs 中获取选定的Book对象并将其显示在give.hbs 中

I wanted to use this line我想用这条线

{{#link-to 'books.give' }} Buy {{/link-to}}

to pass single a single book from books.hbs to give.hbs , but I don't know how to do that and if its the way to go..books.hbs 中的一本书传递give.hbs ,但我不知道该怎么做,以及是否可行

In gift.hbs I partially invented a very inefficient way of doing it by looping all the books again and if the title is a match then display it...gift.hbs 中,我通过再次循环所有书籍部分发明了一种非常低效的方法,如果标题匹配,则显示它......

  {{#each model as |book|}}
    {{#if (eq book.title "Harry Potter")}}
      <h2><b>{{book.title}}</b></h2>
    {{/if}}
  {{/each}}

Obviously the "Harry Potter" string is hard-coded but it could have been passed from books.hbs and that would do the trick since my data is relatively small.显然“哈利波特”字符串是硬编码的,但它可以从books.hbs传递,因为我的数据相对较小,所以可以解决问题。

It depends on how do you want to represent URL.这取决于您想如何表示 URL。
if it's books/give/bookId => then go for dynamic segments如果是books/give/bookId => 然后去动态段
if its books/give?bookId=1 => then go for query params implementation如果它的books/give?bookId=1 => 然后去查询参数实现

Inside books.give route get the particular book record using findRecord and use it.books.give路由中使用findRecord获取特定的书籍记录并使用它。
