Validaform

Rails API form validator

Mount to an endpoint of your application, give it forms fields, and it'll return the validations errors/success in JSON. Really usefull when you want to add on-unblur or before-submit validations.

You post on /validaform/forms/validate a json with this format :

{
  fields: [
    { name: 'users/username', value: 'Asterixlegaulois' },
    { name: 'company/name', value: 'Panoracorp' }
  ]
}.to_json

and the API will send you the validation errors like

{
  fields:[
    {
      name: 'users/username',
      errors: ['too_long', 'too_great_album'],
      count: 2
    },
    {
      name: 'company/name',
      errors: ['taken'],
      count: 1
    }
  ],
  count: 3
}

example with curl =>

curl -X POST -H 'Content-Type: application/json' -d '{"fields":[{"name":"users/first_name","value":"Asterix"},  {"name":"users/last_name","value":"LeGaulois"}, {"name":"companies/size", "value":"17"}]}' http://localhost:3000/validaform/forms/validate

Add this line to your application's Gemfile:

gem 'validaform'

And then execute:

$ bundle

Or install it yourself as:

$ gem install validaform

Then at last, add mount Validaform::Engine, at: '/validaform' inside your Rails.application.routes.draw block of your route.rb
