Request Validator

Request validator is a gem thats allows you do run validation in your controller rather than your models. Why do you need validates :question, presence: true in model when v.check('param').notEmpty() solves it

Installation

No dependency!

$ gem install request_validator

Configuration

Validator.configure do |config|
	config.skip_main_object_empty = true
	config.error_mode = 'surpressed'
end

Config

Dillinger is currently extended with the following plugins. Instructions on how to use them in your own application are linked below.

Option	Description
skip_main_object_empty	Allows your to skip error when the main object is empty. Default is false
error_mode	silences errors and move on to next step

Usage

This gem can be used in two ways and both returns same response in same format.

We will be using this params throughout

{
	"name": "User 1",
	"phone": "789",
	"role" : "admin",
	"email": "[email protected]",
	"website": "https://google.com",
	"actions": ["jsjjd","skskjd"],
}

The first method allows you to match params to methods without explicitly specifying the methods.

Validator.new.validate(params, {
	'name' => 'string',
	'phone' => 'number',
	'email' => 'email',
})

If thers are any errors, response object containing property error as an array containing the error messages is returned

It skips other params if they are not specified...

Method Chaining

Example

v = Validator.new(params)
v.check('email').notEmpty().isEmail()
v.check('name').isString().notEmpty()
v.check('role').isIn(['admin', 'user']).notEmpty()
v.check('actions').isArray()
v.check('website').validUrl()
v.result()

Using this method, it allows changing of methods together. The method check must be specified a parameter is passed into it which is the property to check for.

The params body must me passed into the new method of the validator.

Example response

{
    "error": [
        "phone is not a valid number"
    ]
}
