demand v0.0.3

Demand module

Form error handling for dietjs

How it works?

• You can demand request.body[..] values to match criterias like existence, length etc..
• The module is included in the App module
• The module is accessible in every POST request
• The module can be accessed with the request.demand function
• The module accepts unlimited agruments, each argument by right goes deeper in request.body
• If request.passed is true than the form request has passed
• If request.passed is false then request.errors contains the errors in JSON
• You can answer if - request.passed with request.success(objectResponse) - else request.passed with request.error(objectResponse) - objectResponse is optional

Example

When a POST request comes in (from a form or ajax request) with these parameters:

	{
		'account':{
			username:'adam',
			password:'123456',
		},
		'remain_logged_in': true
	}

You can check is everything is ok with the submitted data with request.check:

var app = new Application(options);

app.get('/login', function(request, response, mysql){
	request.demand('account', 'username').length(0,40);
	request.demand('account', 'password').length(0,40);
	request.demand('remain_logged_in').isBoolean().length(0,1);
	if(request.passed){ 
		response.success();
	} else {
		response.error();
	}
});
