How it works
Build form from specific params and custom validation:
class Address
include ActiveModel::Model
attr_accessor :street, :post_code
end
class Child
include ActiveModel::Model
attr_accessor :name, :age
end
class PersonForm < LightForm::Form
properties :title, :first_name, :last_name
property :email, validates: { presence: true }
property :age, with: -> (v) { v.to_i }
property :address, model: Address do
properties :street, :post_code
end
property :children, collection: Child, uniq: true do
property :name, validates: { presence: true }
property :age, with: -> (v) { v.to_i }
end
property :interests, collection: true, uniq: true
end
person = PersonForm.new(
{
title: 'Mr', first_name: 'Pawel', last_name: 'Awesome', email: nil,
age: '31', address: { street: 'Best', post_code: '33333' },
children: [ {name: 'Emi', age: '2'}, {name: 'Emi', age: '2'}, {age: '2'} ],
interests: [ 'football', 'football', 'basketball', 'football' ]
}
)
person.valid? == false
person.errors.as_json == {
children: [{1=>{name: ["can't be blank"]}}],
email: ["can't be blank"]
}
person.to_h == {
title: 'Mr',
first_name: 'Pawel',
last_name: 'Awesome',
email: nil,
age: 31,
address: <AddressModel:0x007faf0ba22238 @street='Best', @post_code='33333'>,
children: [<ChildModel:0x007faf0ba21ec8 @name='Emi', @age=2>, <ChildModel:0x007faf0ba21c70 @name='', @age=2>],
