[英]ember-data hasMany relationship using json
我正在尝试使用ember-data hasMany关系,以便我的作者链接可以复制所有作者,并且当您单击特定作者时,该页面还提供了指向他的书的链接。 单击特定书籍时,它会提供指向其作者的链接。 它与fixtures完美配合,但是ajax调用出了点问题。 非常感谢您的帮助。
我的app.js:
App = Ember.Application.create({});
App.Store = DS.Store.extend({
adapter: DS.RESTAdapter.extend()
});
App.Author = DS.Model.extend({
name: DS.attr('string'),
biography: DS.attr('string'),
book_ids: DS.hasMany('book', { async: true })
});
App.Book = DS.Model.extend({
name: DS.attr('string'),
description: DS.attr('string'),
image: DS.attr('string'),
author_ids: DS.hasMany('author', { async: true })
});
App.Router.map(function() {
this.resource('about');
this.resource('books', function() {
this.resource('book', { path: '/:book_id' });
});
this.resource('authors', function() {
this.resource('author', { path: '/:author_id' });
});
});
App.BooksRoute = Ember.Route.extend({
model: function() {
return App.Book.findAll();
}
});
App.Book = Ember.Object.extend();
App.Book.reopenClass({
findAll: function() {
return $.getJSON('/json/books.json').then(function(response) {
var books=[];
response.book.forEach( function (book) {
books.push( App.Book.create(book) );
});
return books;
});
}
});
App.AuthorsRoute = Ember.Route.extend({
model: function() {
return App.Author.findAll();
}
});
App.Author = Ember.Object.extend();
App.Author.reopenClass({
findAll: function() {
return $.getJSON('/json/authors.json').then(function(response) {
var authors=[];
response.author.forEach( function (author) {
authors.push( App.Author.create(author) );
});
return authors;
});
}
});
json中的数据表示如下:
{
"author": [
{
"id": 1,
"name": "James Joyce",
"biography": "<p><b>James Joyce</b> <small>(February 2, 1882 - January 13, 1941)</small> was one of the most preeminent Irish authors of the twentieth century. He is known for his literary innovation such as a strictly focused narrative and indirect style. Although not strictly originally, James Joyce brought the aforementioned writing methods were to an unparalleled height.</p>",
"book_ids": ["1", "2"]
},
{
"id": 2,
"name": "F. Scott Fitzgerald",
"biography": "<p><b>Francis Scott Key Fitzgerald</b> <small>(September 24, 1896 – December 21, 1940)</small> was an American author of novels and short stories, whose works are the paradigmatic writings of the Jazz Age, a term he coined. He is widely regarded as one of the greatest American writers of the 20th century. Fitzgerald is considered a member of the 'Lost Generation' of the 1920s. He finished four novels: This Side of Paradise, The Beautiful and Damned, The Great Gatsby (his most famous), and Tender Is the Night. A fifth, unfinished novel, The Love of the Last Tycoon, was published posthumously. Fitzgerald also wrote many short stories that treat themes of youth and promise along with age and despair.</p>",
"book_ids": ["3", "4"]
}
]
}
您正在编写模型定义,然后不使用商店来获取记录。 我在jsbin中简化了您的代码。
App.BooksRoute = Ember.Route.extend({
model: function() {
return this.store.find('book');
}
});
App.AuthorsRoute = Ember.Route.extend({
model: function() {
return this.store.find('author');
}
});
App.ApplicationAdapter= DS.RESTAdapter.extend({
host:'json',
pathForType: function(type) {
return Ember.String.pluralize(type) + '.json';
}
});
