我正在尝试将一个非常大的文本保存到我的mongodb数据库中，但它崩溃了。我正在尝试构建一个代码段管理器，这是我的错误代码：
{ [MongoError: Btree::insert: key too large to index, failing beverages.recipes.$code_1 3271 { : "var gulp = require('gulp');
var source = require('vinyl-source-stream');
var browserify = require('browserify');
var browserSync = require('browser-sy..." }]

这是我的猫鼬模型。
import mongoose from 'mongoose';
const Schema = mongoose.Schema;
let recipeSchema = new Schema({
title: { type: String, required: true },
author: { type: String},
tags: { type: String, required: true },
code: { type: String, required: true, unique: true, index: true },
created_at: Date,
updated_at: Date
});
recipeSchema.pre('save', function(next) {
var recipe = this;
// get the current date
var currentDate = new Date();
// change the updated_at field to current date
recipe.updated_at = currentDate;
// if created_at doesn't exist, add to that field
if (!recipe.created_at){
recipe.created_at = currentDate;
}
next();
});
let Recipe = mongoose.model('Recipe', recipeSchema);
export default Recipe;
如果是found this on mongodb，但我不知道如何使用mongoose来使用它。这是正确的做法吗？
这是我试图保存的文件

非常感谢你的帮助！

您似乎正在尝试使用字段code作为索引。根据您的链接，code值的大小约为3KB。 Mongo的限制为index fields must not exceed 1KB。 3> 1因此，您收到此错误。
您可以通过以下方式解决此问题：

对于索引代码字段，请使用文本索引。对于唯一使用哈希表单代码。 例如：
import crypto from 'crypto';
let recipeSchema = new Schema({
title: { type: String, required: true },
author: { type: String},
tags: { type: String, required: true },
code: { type: String, required: true },
codeHash: {type: String, unique: true },
created_at: Date,
updated_at: Date
});
recipeSchema.index({code: 'text'}
recipeSchema.pre('save', function(
var recipe = this;
// get the current date
var currentDate = new Date();
// change the updated_at field to current date
recipe.updated_at = currentDate;
// if created_at doesn't exist, add to that field
if (!recipe.created_at){
recipe.created_at = currentDate;
}
var hash = crypto.createHash('md5').update(this.code).digest("hex")
this.codeHash = hash;
next();
});
