Default Schema don't filter undescribed params

[semenovDL]

require 'dry-validation'

schema = Dry::Validation.Schema do
  required(:email).filled(:str?)
end

validated =  schema.call(email: 'admin@google.com', password: 'hackyou')
puts validated.success? # => true
puts validated.output # => {:email=>"admin@google.com", :password=>"hackyou"}

I think that such behavior is OK. Because we do not specify that any other params should be filtered. Maybe it is good idea to implement such DSL:

schema = Dry::Validation.Schema do
  method :default # as it used to be
  method :strict # makes :success? to be false if any not declared keys are present
  method :filter # just filters keys not declared keys
end

This was considered as bug and solved
#66

Howto:

Dry::Validation.Schema do
  configure do
    config.input_processor = :sanitizer
  end

  key(:email).required

  key(:age).maybe(:int?, gt?: 18)

  key(:address).schema do
    key(:city).required
    key(:street).required
  end
end

result = schema.(
  email: 'jane@doe',
  age: 19,
  such: 'key',
  address: { city: 'NYC', street: 'Street', wow: 'bad' }
)

result.output
# {  email: 'jane@doe', age: 19, address: { city: 'NYC', street: 'Street' }

Yep. I arrived here after looking at #66. Add config.input_processor = :sanitizer.

This will be the default behavior in the next release

I thought sanitizer is already the default setting but apparently its not. Is there a way to set this as the default setting without having to create a base schema that every other schemas have to nest with?

@mengqing no, you either configure it in each schema, or use a base schema and inherit from it

@solnic Thanks for the quick reply
