我试图更新嵌套数组中的值,但无法使其工作.
我的目标是这样的
{
"_id": {
"$oid": "1"
},
"array1": [
{
"_id": "12",
"array2": [
{
"_id": "123",
"answeredBy": [],
},
{
"_id": "124",
"answeredBy": [],
}
],
}
]
}

我需要将值推送到"answersBy"数组.
在下面的例子中,我尝试将"success"字符串推送到"123 _id"对象的"answersBy"数组,但它不起作用.
callback = function(err,value){
if(err){
res.send(err);
}else{
res.send(value);
}
};
conditions = {
"_id": 1,
"array1._id": 12,
"array2._id": 123
};
updates = {
$push: {
"array2.$.answeredBy": "success"
}
};
options = {
upsert: true
};
Model.update(conditions, updates, options, callback);

我找到了这个链接,但它的答案只说我应该使用类似对象的结构而不是数组.这不适用于我的情况.我真的需要我的对象嵌套在数组中
如果你能在这里帮助我会很棒.我花了好几个小时来搞清楚这一点.
先感谢您!
有没有办法允许Django应用程序接受自定义接受标头,如"application/vdn.name.v1 + json"?
我一直得到这样的回复

我也在使用Django Rest Framework
当请求包含“api”子域时,我试图用另一个 url 覆盖 ROOT_URLCONF ,这就是我到目前为止所拥有的。
from django.utils.cache import patch_vary_headers
class SubdomainMiddleware:
def process_request(self, request):
path = request.get_full_path()
root_url = path.split('/')[1]
domain_parts = request.get_host().split('.')
if (len(domain_parts) > 2):
subdomain = domain_parts[0]
if (subdomain.lower() == 'www'):
subdomain = None
else:
subdomain = None
request.subdomain = subdomain
request.domain = domain
if request.subdomain == "api":
request.urlconf = "rest_api_example.urls.api"
else:
request.urlconf = "rest_api_example.urls.

我也尝试使用 set_urlconf 模块“来自 django.core.urlresolvers”,但它不起作用。我在这里错过了什么吗?
python django django-middleware django-urls django-rest-framework
我现在正在使用 Unity 开发一个 iOS 应用程序,我正在尝试设置关联的域,而无需在 xcode 上手动设置它。我相信我可以实现这一目标,PostProcessBuild但我无法想象
public class AvametricIOSBuildPostProcessor
{
static string[] associatedDomains;
[PostProcessBuild]
public static void OnPostprocessBuild (BuildTarget target, string pathToBuiltProject)
{
if (target == BuildTarget.iOS)
OnPostprocessBuildIOS (pathToBuiltProject);
}
private static void OnPostprocessBuildIOS (string pathToBuiltProject)
{
var projectCapabilityManager = new ProjectCapabilityManager(plistPath, plistPath, "Unity-iPhone");
associatedDomains[0] = "applinks:XXXXX";
projectCapabilityManager.AddAssociatedDomains(associatedDomains);
}

如何在动画后删除课程?
我试图使用Mongoose创建一个动态条件,但它不像我想象的那样工作.
代码是这样的
id = req.params.questionId;
index = req.params.index;
callback = function(err,value){
if(err){
res.send(err)
}else{
res.send(value)
}
};
conditions = {
"_id": id,
"array._id": filterId
};
updates = {
$push: {
"array.$.array2."+index+".answeredBy": userId
}
};
options = {
upsert: true
};
Model.update(conditions, updates, options, callback);

如您所见,我正在尝试使用"index"变量创建动态条件.有可能这样做吗?
