What is the curd operation of MongoDB in THINKJS? tutorial on the use of curd operations

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) { Returnthis.select (); }

Paging Plus Conditional Search

Search (q, page) { if (q) { Q =newregexp (q, ' I '); } Returnthis.where ({' name ': {$regex: Q}}). page (page). Countselect (); }

Get details

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

Creating data

Addtag (TAG) { Returnthis.add (tag); }

Update data

Updatetag (Id,data) { Returnthis.where ({' _id ': ID}). Update (data); }

Delete data

Removeone (ID) { Returnthis.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 '); Get 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); } } ....
