Security Issues

If you discover a security vulnerability in untitled-model, please see Security Policies and Procedures.

Quick Start

Start new project

$ mkdir myWeb && cd myWeb
$ node init
$ node i untitled-model

Create model:

# make sure your current dir should be ~/myWeb/ 
$ mkdir models
$ touch ./models/user.json

User model :

Copy and past this inside ~/models/user.json

{
  "id" : {"dtype":"int","primary":true,"unique":true,"size":8,"auto-inc":true},
  "name" : {"dtype":"string","size":100},
  "address" : {"dtype":"text"},
  "password" : {"dtype":"string","size":100,"secure":true}
}

Migrating models

/myWeb/test.js

var model = require('untitled-model');
model.connection(
    {   
        host: "localhost",
        user: "root",
        password: "",
        database:"test"
    }
);
model.migrate('user.json');

Philosophy

The untitled-model philosophy is to provide a tool for programmers to send and receive data to and from sql database. Migrate function is use to generate tables inside database. It supports relational database foreign key concept.

foreign key

department.json

{
    "id" : {"dtype":"int","primary":true,"auto-inc":true},
    "name" : {"dtype":"string","size":100}
}

user.json

{
    "id" : {"dtype":"int","primary":true,"unique":true,"size":8,"auto-inc":true},
    "name" : {"dtype":"string","size":100},
    "address" : {"dtype":"text"},
    "password" : {"dtype":"string","size":100,"secure":true},
    "department":{"dtype":"foreign", "model":"department"}
 }
 

Functions

• ### User = model.get('user')

       User = { 
        model: 'user',
        all: [Function],
        filter: [Function],
        values: [Function],
        update: [Function],
        insert: [Function],
        delete: [Function] ,
        
        m: { 
              model: 'user',
              select: [],
              FILTER: [],
              join: '',
              buffer: [],
              show: [Function],
              value: [Function],
              filter_: [Function],
              values: [Function],
              filters: [Function],
              rename: [Function] 
          },
       }

• ##### User.all(callback) requires sql connection

     // It returns data to callback unction
     all(callback){
       let table = this.model;
       let project = this.m.select;
       . . .
       . . .
       query = "select " +select+" from " + table ;
       . . . 
       callback(error, data);
     }
   
  Example:
   
    User.all(function(err,data){
     if(e) throw e;
     console.log(data);
    });

• ##### User.filter({},callback) requires sql connection

      // It returns data to callback unction
      filter({id:5},callback){
        let table = this.model;
        let project = this.m.select;
        . . .
        . . .
        query = "select " +select+" from " + table + " WHERE " + filters;
        . . . 
        callback(error, data);
      } 
   
   Example:
     User.filter({'id': 2},callback);
     User.filter({'id > ': 2},callback);
     User.filter({'id': 2,'name':'someone'},callback);
     
     User.filter({'id': 2},function(err,data){
         if(err) throw err;
         console.log(data);
     });

• ##### User.values(['attr']) sql projection

  • use __ for foreign table

        // It returns data to callback unction
        function(select=[]){
          . . .
          _set_select_vlaues_
          . . . 
          return this.m;
        }
        
        Example:
              User = User.values(['name','department__name'])
              User.all((error, data)=>{
                  if(error) throw error;
                  console.log(data);
              });
               
                       // or
                
              User = User.values(['name','department__name'])
              User.filter({id:5},(error, data)=>{
                  if(error) throw error;
                  console.log(data);
              })

    • ##### show() // returns Query string
    • ##### rename({}) // rename the attributes in query string

        rename({name:"UserName"});

    • filter(callback)
    • all(callback)

• ##### update({}) returns model

      User.update({name:'pankaj'}).filter({name:'pankajdevesh'},(e, data)=>{
          if(e) throw  e;
          console.log(data);
      });

• ##### insert({}, callback) insert into database

        User.insert({name:'javascript'},(error, data)=>{
          if(error) throw error;
          console.log(data);
        });

• ##### delete().filter({},callback) delete from database

        User.delete().filter({id:5},(error, data)=>{
          if(error) throw error;
          console.log(data);
        });
