Accesor_MongoDB 0.1.1

A wrapper for Access to connect with ease and flexiblity.

Package Install

Install via npm is a prefer way for users to obtain a copy of Access_MongoDB
```
npm install Accessor_MongoDB
```

Create a config directory under your application directory, create a file called database.js which may contains like this:

var databaseConfig = { 
	// server
	host: "localhost",
	
	server_options: {
		auto_reconnect: true,
	},  

	// database
	name: "ddns",
	
	db_options: {
		native_parser: true,
	},  
};

module.exports = databaseConfig;

Now, Accessor_MongoDB is ready.

Usage

Require the Accessor module in your script
Place constructor where you need that. And don't forget to specify database engine.
```
var tester = Accessor("YOUR_TARGET_COLLECTION", "MongoDB");
```
After initialization, Accessor will connect to MongoDB server.

Methods

accessor.select( {options}, callback(err, data_fields) );

Perform a select query to obtain data, for example:

	var tester = Accessor("test_collection");
	
	var options = {
		where: {
			name: "bu"
		},
		
		limit: 100,
		offset: 50,
		
		fields: ["name"]
	};
	
	tester.select( options, function(err, data) {
		if(err) {
			throw err;
		}	
		
		return data;
	});

Currently, {options} has implements following attributes:

where
limit
offset
fields

Note

Options may omit, which retrieve all records, i.e.

	var tester = Accessor("test_collection");
	
	tester.select( function(err, data) {
		if(err) {
			throw err;
		}	
		
		return data;
	});

accessor.create( {dataObject}, callback(err, info) );

Insert data record by given dataObject

	var tester = Accessor("test_collection");
	
	var dataObject = {
		name: "bu",
		email: "bu@hax4.in",
	};
	
	tester.create( dataObject, function(err, info) {
		if(err) {
			throw err;
		}	
		
		return info.insertId;
	});

accessor.update( {options}, {dataObject}, callback(err, info) );

Update records filter by option.where with updated_dataObject

	var tester = Accessor("test_collection");
	
	var dataObject = {
		email: "bu@hax4.in",
	};
	
	var options = {
		where: {
			username: "bu"
		}
	};
	
	tester.update( options, dataObject, function(err, info) {
		if(err) {
			throw err;
		}	
		
		return info.affectedRows;
	});

If options is omitted, it will update all records. (due to no filter)

		var tester = Accessor("test_collection");
	
		var dataObject = {
			email: "bu@hax4.in"
		};

		tester.update( {}, dataObject, function(err, info) {
			if(err) {
				throw err;
			}	
		
			return info.affectedRows;
		});

accessor.remove( {options}, callback(err, info) );

Remove records filter by options.where

	var tester = Accessor("test_collection");
	
	var options = {
		where: {
			username: "bu"
		}
	};
	
	tester.update( options, function(err, info) {
		if(err) {
			throw err;
		}	
		
		return info.affectedRows;
	});

Note

If options is omitted, it will remove all records. (due to no filter)

		var tester = Accessor("test_collection");

		tester.remove( {}, function(err, info) {
			if(err) {
				throw err;
			}	
		
			return info.affectedRows;
		});
