Why does mongoose always add an s to the end of my collection name
提问by Bob Ren
For example, this code results in a collection called "datas" being created
例如，此代码导致创建一个名为“datas”的集合
var Dataset = mongoose.model('data', dataSchema);
And this code results in a collection called "users" being created
这段代码导致创建一个名为“users”的集合
var User = mongoose.model('user', dataSchema);
Thanks
谢谢

Mongoose is trying to be smart by making your collection name plural. You can however force it to be whatever you want:
Mongoose 试图通过使您的收藏名称复数来变得聪明。但是，您可以强制它成为您想要的任何内容：
var dataSchema = new Schema({..}, { collection: 'data' })
var dataSchema = new Schema({..}, { collection: 'data' })

API structure of mongoose.model is this:
mongoose.model 的 API 结构是这样的：
Mongoose#model(name, [schema], [collection], [skipInit])
What mongoose do is that, When no collection argument is passed, Mongoose produces a collection name by pluralizing the model name. If you don't like this behavior, either pass a collection name or set your schemas collection name option.
mongoose 所做的是，当没有传递集合参数时，Mongoose 通过将模型名称复数化来生成集合名称。如果您不喜欢这种行为，请传递一个集合名称或设置您的架构集合名称选项。
Example:
例子：
var schema = new Schema({ name: String }, { collection: 'actor' });
or
或者
schema.set('collection', 'actor');
or
或者
var collectionName = 'actor'
var M = mongoose.model('Actor', schema, collectionName);

Starting from mongoose 5.x you can disable it completely:
从 mongoose 5.x 开始，您可以完全禁用它：
mongoose.pluralize(null);

You can simply add a string as a third argument to define the actual name for the collection. Extending your examples, to keep names as dataand userrespectively:
您可以简单地添加一个字符串作为第三个参数来定义集合的实际名称。扩展您的示例，分别保留名称data和名称user：
var Dataset = mongoose.model('data', dataSchema, 'data');
var User = mongoose.model('user', dataSchema, 'user');

You can add the collection name as third parameter. See the example using Typescript:
您可以添加集合名称作为第三个参数。请参阅使用 Typescript 的示例：
import DataAccess = require('../DataAccess');
import IUser = require("../../Models/Interfaces/IUser");
var mongoose = DataAccess.mongooseInstance;
var mongooseConnection = DataAccess.mongooseConnection;
class UserSchema {
static get schema () {
var schema = mongoose.Schema({
_id : {
type: String
},
Name: {
type: String,
required: true
},
Age: {
type: Number,
required: true
}
});
return schema;
}
}
var schema:any = mongooseConnection.model<IUser>("User",
UserSchema.schema,"User");
export = schema;

//Mongoose's definition file. NOT your model files
1 const mongoose = require("mongoose");
2 mongoose.pluralize(null);
Adding the linemongoose.pluralize(null)in your Mongoose file will prevent collection name pluralization. You don't need to add this line to your model files.
mongoose.pluralize(null)在您的 Mongoose 文件中添加该行将阻止集合名称的复数形式。您不需要将此行添加到模型文件中。
As seen here.
如这里所见。

At the end of defining your schema on the next line Use this code
在下一行定义架构的末尾使用此代码
module.exports = mongoose.model("State", "StateSchema", "state")
Assuming that your state is what you want to use on your db to avoid s as states
假设您的状态是您想在数据库上使用的状态以避免 s 作为状态
