Overview

Provides validates DSL to controllers to validate params.

Examples

# POST /recipes { name: "alice" }              #=> 201
# POST /recipes { name: "alice", type: 1 }     #=> 201
# POST /recipes { name: "alice", type: "bob" } #=> 400
# POST /recipes { type: 1 }                    #=> 400
class RecipesController < ApplicationController
rescue_from WeakParameters::ValidationError do |exception|
  render text: exception.message, status: 400
end

validates :create do
  string :name, required: true
  integer :type
end

def create
  respond_with Recipe.create(params.slice(:name, :type))
end
end

# WeakParameters.stats has its definitions.
WeakParameters::stats[:recipes][:create].validators[0].key       #=> :name
WeakParameters::stats[:recipes][:create].validators[0].required? #=> true
WeakParameters::stats[:recipes][:create].validators[1].key       #=> :type
WeakParameters::stats[:recipes][:create].validators[1].required? #=> false
