您好我想創建通過貓鼬一個新的子文檔,但我發現下面的消息時,我在郵差執行POST方法:消息:路徑需要
{
"message": "Location validation failed",
"name": "ValidationError",
"errors": {
"reviews.1.reviewText": {
"message": "Path `reviewText` is required.",
"name": "ValidatorError",
"properties": {
"type": "required",
"message": "Path `{PATH}` is required.",
"path": "reviewText"
},
"kind": "required",
"path": "reviewText"
},
"reviews.1.rating": {
"message": "Path `rating` is required.",
"name": "ValidatorError",
"properties": {
"type": "required",
"message": "Path `{PATH}` is required.",
"path": "rating"
},
"kind": "required",
"path": "rating"
},
"reviews.1.author": {
"message": "Path `author` is required.",
"name": "ValidatorError",
"properties": {
"type": "required",
"message": "Path `{PATH}` is required.",
"path": "author"
},
"kind": "required",
"path": "author"
}
}
}
這裏是我的DB模式爲位置:
var mongoose = require('mongoose');
var reviewSchema = new mongoose.Schema({
author: {type: String, required: true},
rating: {type: Number, required: true, min: 0, max: 5},
reviewText: {type: String, required: true},
createdOn: {type: Date, "default": Date.now}
});
var openingTimeSchema = new mongoose.Schema({
days: {type: String, required: true},
opening: String,
closing: String,
closed: {type: Boolean, required: true}
});
var locationSchema = new mongoose.Schema({
name: {type: String, required: true},
address: String,
rating: {type: Number, "default":0, min: 0, max: 5},
facilities: [String],
coords: {type: [Number], index:'2ndsphere'},
openingTimes: [openingTimeSchema],
reviews: [reviewSchema]
});
mongoose.model('Location', locationSchema);
這裏下router.post啓動控制器( '/位置/:locationid /評論',ctrlReviews.reviewsCreate);路由:
//reviews.js
var mongoose = require('mongoose');
var Loc = mongoose.model('Location');
module.exports.reviewsCreate = function (req, res) {
var locationid = req.params.locationid;
if(locationid){
Loc
.findById(locationid)
.select('reviews')
.exec(
function(err, location){
if(err){
sendJsonResponse(res, 400, err);
} else{
console.log(location);
doAddReview(req, res, location);
}
}
);
} else{
sendJsonResponse(res, 400, {
"message" : "Not found, locationid required"
});
}
};
// START - Functions for review create //////////////////////////////////////
var doAddReview = function(req, res, location){
if(!location){
sendJsonResponse(res, 404, "locationid not found");
} else{
location.reviews.push({
author: req.body.author,
rating: req.body.rating,
reviewText: req.body.reviewText
});
location.save(function(err, location){
var thisReview;
if(err){
//sendJsonResponse(res, 400, err);
sendJsonResponse(res, 400, err);
} else{
updateAverageRating(location._id);
thisReview = location.reviews[location.reviews.length - 1];
sendJsonResponse(res, 201, thisReview);
}
});
}
};
var updateAverageRating = function(locationid){
console.log("Update rating average for", locationid);
Loc
.findById(locationid)
.select('reviews')
.exec(
function(err, location){
if(!err){
doSetAverageRating(location);
}
}
);
};
var doSetAverageRating = function(location){
var i, reviewCount, ratingAverage, ratingTotal;
if(location.reviews && location.reviews.length > 0){
reviewCount = location.reviews.length;
ratingTotal = 0;
for(i=0; i<reviewCount; i++){
ratingTotal = ratingTotal + location.reviews[i].rating;
}
ratingAverage = parseInt(ratingTotal/reviewCount, 10);
location.rating = ratingAverage;
location.save(function(err){
if(err){
console.log(err);
} else{
console.log("Average rating updated to", ratingAverage);
}
});
}
};
執行location.save功能時,我已經看到了這個錯誤彈出。我正在通過一本書學習MEAN Stack,因此您可以在此處下載本章的完整代碼:https://github.com/simonholmes/getting-MEAN/tree/chapter-06
我試過從app_api替換我的locations.js和reviews.js文件的代碼/ controllers文件夾,但在這一點上應用程序崩潰,我猜是因爲其他文件需要更新。 所以我卡在那裏。
有誰知道爲什麼會發生?
在此先感謝!
有一個類似的問題發生在我身上,而沿着這個東西是什麼解決了它。 –
Joshua我已經配置了這種方式,但我並沒有放棄這個問題來自一些分析錯誤,因爲每次我安裝一個模塊時,我都會面臨如下幾個警告:「npm WARN EJSONPARSE無法解析json」,也許這是相關的,但我找不到任何解決方案(緩存清除不解決)。 – AtomicNation
