Mongoose Meanjs无法将图像保存到嵌套架构中
我的Meanjs应用程序应该将徽标上传到我的UserSchema中的嵌套模式中。我能够成功上传文件，因为我能够为用户成功存储个人资料照片。但是，当我试图将图像保存到嵌套模式中时，它失败了 我的模型看起来像这样：Mongoose Meanjs无法将图像保存到嵌套架构中,mongoose,mean,meanjs,Mongoose,Mean,Meanjs,我的Meanjs应用程序应该将徽标上传到我的UserSchema中的嵌套模式中。我能够成功上传文件，因为我能够为用户成功存储个人资料照片。但是，当我试图将图像保存到嵌套模式中时，它失败了 我的模型看起来像这样： ClubSchema = {name:String, logo:Buffer}; UserSchema = {name:String, photo:Buffer, club:[ClubSchema]
ClubSchema = {name:String,

var user = new Users($scope.user);
console.dir(user.club); //I can see the logo here
for(var i = 0;i<user.club.length;i++){
user.club[i].logo = $scope.uploadedLogos[i]; //Still trying to force it into the object
user.club[i].hasLogo = true; //Mysterious hasLogo = false appears
}

$scope.success = true;

user = _.extend(user, req.body);
user.updated = Date.now();
user.displayName = user.name;
user.save(function(err) {
if (err) {
return res.status(400).send({
message: errorHandler.getErrorMessage(err)
});
} else {
req.login(user, function(err) {
if (err) {
res.status(400).send(err);
} else {
res.json(user);
}
});
}
});
} else {
res.status(400).send({
message: 'User is not signed in'
});
}
hasLogo字段完全令人困惑，因为我的代码中不存在这样的赋值。我添加了hasLogo=true，希望它能以某种方式将hasLogo设置为true，然后上传图像，但这也不起作用。我不知道这个hasLogo是从哪里来的。在hasLogo=true循环之后，如果打印对象，我可以看到两个hasLogo字段，一个为true，另一个为false。在$update成功之后，它总是false。我的模型不包含hasLogo字段。这是我使用MEAN.JS上传文件的方式 型号

这对我来说很好。希望这有帮助 user.club[i].徽标就是徽标所在的位置，对吗。。？$scope.uploadedLogos[i]有什么？$scope.uploadedLogos[i]只是我创建的一个单独的数组，用于获取正在上载的徽标的辅助存储，然后将它们重新分配给$scope.user.club[i]。logo，以防它被删除。没有帮助，因为它仍然在我试图更新的最终用户对象中被删除。与最终用户对象没有实际关联。只是我在尝试的东西。我试图使用$scope.user更新的最后一个var用户仍然不包含徽标您从客户端获得的徽标是这种格式的吗？“数据：图像/png；base64，Ivborw0kgoaansuheugaac4aaahocamaamobmcaaaam1bmveuyicg9j8pjlcxum85godbrp9j3rdscs9nudizv9ukxd2wy9+70eh1+PS3eXe4+fp6elaxdwaaamg0leqvr42u3d7qkgyf4aiuyra/ed7fvvt96e7te3jkjkjkjkjkjkjkj4cwkj4cwkjkjjkjkjkjkjkjkjkjkjkjkjkjkjkjkjkwkjkjkjkjkjkjkjkjkwkjkjkjkjkjkjkwg8wg8wkjkjkjkjkjkjkjjjINGRNOAIEBK8BKJVHCMTMY4H18ZX7IKVODSYGHGNYZL/ZXTIYLHVFGDJ8TXKXZOGUBU4NSAV8YRHMS5RHLNVTCOZZLOKGBIWL7KIYCLWTL4TL0MUY9S9ANECF=”是的，我正在使用ng file upload指令上载文件。用户的照片上传完全使用此指令。顺便说一句，我找到了一个解决方案，将Club作为一个单独的模块，并与用户模型分开创建/更新它。不确定这是否是正确的方法，但它是有效的。我很想知道最初的实现有什么问题。我已经能够成功上传图片了。问题在于将其插入mongodb文档中的嵌套字段中。
