Parse.com Javascript SDK使用include,但不起作用 [英] Parse.com Javascript SDK using include, but not working
问题描述
我正在尝试从名为 Book
的表中获取数据。在 Book
里面有一个指针< ParseUser>
,它包含一个用户的指针。 ParseUser
有另一个名为 Pais
的指针(这意味着西班牙语为Country)。所以我想从任何 Book
中获取每一个信息:
I'm trying to fetch data from a table called Book
. Inside Book
there's a Pointer<ParseUser>
which holds the pointer of one user. The ParseUser
has another pointer called Pais
(which means Country in spanish). So I want to fetch every single info from any Book
:
var query = new Parse.Query("Book");
query.include("user");
query.include("user.pais");
query.find({
success: function(books) {
response.success(books);
},
error: function(error) {
response.error({'resp': error.code, 'message': error.message});
}
});
我没有得到对象,只是指针:
and I don't get the objects, just the pointers:
为什么?我知道当我在iOS或Android中使用 include(String key)
或 includeKey:NSString * key
。
Why ? I know it works ok when I call it in iOS or Android with include(String key)
or includeKey: NSString* key
.
为什么不能用Javascript工作?
Why doesn't it work with Javascript??
提前谢谢。
问候。
Rafael。
编辑:
哦,我忘记了......我试过了:
Oh and I just forgot... I've tried with:
query.include([user]);
和
query.include([user,user.pais]);
我见过一些开发人员使用它的例子。
I've seen some examples where developers used it.
第二次编辑:
我用过的最后一件事是 fetch
喜欢:
The last thing I've used is fetch
like:
Parse.Object.fetchAll(books, {
success: function(list) {
response.success(list);
},
error: function(error2) {
response.error({'resp': error2.code, 'message': error2.message});
},
});
但也没有用。
这开始吓坏了我。
我们的工作方式:
我们尝试做的解决方法是分别获取所有内容,然后一起返回给用户。这不是一个好习惯,因为未来课程的一点变化会破坏整个功能。
OUR WORKAROUND: The workaround we're trying to do is fetching everything separately, and then returning back to the user together. This is not a good practice since a little change in the class in a future would ruin the whole function.
这是SDK中的错误吗?
Is this a bug in the SDK ?
推荐答案
(这是一个评论转化为答案)
只是一个想法,因为我最近遇到的CloudCode与你的问题非常相似。您使用的是哪个版本的JavaScript SDK?我通过将版本更改回1.4.2解决了我的问题。在你的情况下,这只是一个黑暗的镜头,但它可能会工作。
Just a thought because I recently had a problem with CloudCode that is quite similar to yours. What version of the JavaScript SDK are you using? I solved my problem by changing the version back to 1.4.2. It's just a shot in the dark in your case, but it might work.
这里是我描述问题的线程以及如何通过更改SDK版本来解决它。
Here is the thread where I described the problem and how to solve it by changing the SDK version.
