除非调用
Meteor.call
并让服务器端方法进行更新,否则所有客户端代码都被视为不可信。如果在控制台中查看,可能会看到如下错误:
{
error: 403,
reason: "Not permitted. Untrusted code may only update documents by ID.",
details: undefined, message: "Not permitted. Untrusted code may only update documents by ID. [403]",
errorType: "Meteor.Error"
}
在客户端,一次只能更新1个文档,并且必须选择要按ID更新的文档,因此第一个参数必须是mongo文档ID,而不是mongo选择器:
MyCollection.update(
this._id,
{
$set: { "admin_section.1.access_policy": "TEST" }
}
)
另外,要更新数组的子文档,而不是在第一个参数中指定ID作为选择器,请注意我是如何在$set
语句中指定ID的
如果要更新数组中的所有元素,则必须逐个循环所有元素:
var doc = MyCollection.findOne(this._id);
var adminSections = doc.admin_section;
for (i = 0; i < adminSections.length; i++) {
// If you need to access a value in the nested doc:
var nestedDoc = adminSections[i];
MyCollection.update(
this._id,
{
$set: { "admin_section." + (i+1) + ".access_policy": "someValue" }
}
);
{
var doc=MyCollection.findOne(this.\u id);
var adminSections=doc.admin\u节;
对于(i=0;i
它仅适用于“admin\u section”的第一个数组,但我必须根据数组的Id将每个数组的“access\u policy”更新为动态,请提供帮助。请参阅更新的答案-这就是您要查找的吗?
var doc = MyCollection.findOne(this._id);
var adminSections = doc.admin_section;
for (i = 0; i < adminSections.length; i++) {
// If you need to access a value in the nested doc:
var nestedDoc = adminSections[i];
MyCollection.update(
this._id,
{
$set: { "admin_section." + (i+1) + ".access_policy": "someValue" }
}
);
