[英]Parse - get parent items with their child items in array one to many relation
我的Parse模式中有以下关系:“Post”项目带有“Comments”子项。 我正在使用Arrays for One-to-Many Relations,如下所述: relations_guide
如何获取所有帖子(即使没有评论的帖子)以及每篇帖子的所有评论?
我正在尝试这样的事情:
var post = Parse.Object.extend("post");
var comment = Parse.Object.extend("comment");
var queryPosts = new Parse.Query(post);
var queryComments = new Parse.Query(comment);
queryPosts.matchesQuery("commentsList", queryComments);
return queryPosts.find().then(function (postsResult) {
console.log('prepareResponses: number of posts found: ' + postsResult.length);
然后,当然,我想得到这样的评论可能吗?
p = postsResult[0].get("commentsList");
console.log("Number of comments in the first post is: " + p.length);
我想查询特定类中的所有行(假设comments是post中的关系对象):
var post = Parse.Object.extend("post");
var postQuery = Parse.Query(post);
postQuery.includeKey("comments");
//post query will return all rows in post class with the comments relation loaded
