How to use the MongoDB curd Operation _javascript Class library in Thinkjs

Objective

It is well known that the current use of Node.js + MongoDB has become a technology stack for many companies. Thinkjs actually provides support for MONGO, although the official documentation is small, but the ORM API is guaranteed to be consistent, so use it to see the basic >model API

The basic model files are placed under Common/model

Get list

GetList (q, page) {return 
 this.select ();
 }

Paging Plus Conditional Search

Search (q, page) { 
 if (q) {
  q = new RegExp (q, ' I ');
 }
 Return This.where ({' name ': {$regex: Q}}). page (page). Countselect ();
 }

Get details

Getdetail (ID) {return 
  this.where ({' _id ': id}). Select (); 
 

Creating data

Addtag (tag) {return 
 This.add (tag);
 }

Update data

Updatetag (id,data) {return 
 this.where ({' _id ': ID}). Update (data);
 

Delete data

 Removeone (ID) {return
 this.where ({' _id ': id}). Delete ();
 }

So what you need is just the way to call the appropriate model.

A simple interface is as follows:

Async CreateAction () {let 
 name = This.post (' name ');
 Let contents = this.post (' contents ');
 Gets the model instance let
 m = This.model (' tag ');
 Let res = await M.addtag ({
  ' name ': Name,
  ' contents ': Contents,
  ' count ': 0,
 });
 if (res) {
  this.success (');
 } else{
  this.apierrorhandle (4000);
 }
 ....
