Question

Modelo contact.Rb:

class Contact
  include ActiveModel::Validations
  include ActiveModel::Conversion
  extend ActiveModel::Naming

  attr_accessor :name, :email, :message, :subject

  validates_presence_of :name, :subject, :email, :message
  validates_format_of :email, with: /\A[a-z0-9.]+(\+[a-z0-9_-]+)?@[a-z0-9.-]+\.[a-z]{2,4}\z/
  validates_length_of :message, minimum: 10, maximum: 500

  def initialize(attributes = {})
    attributes.each do |name, value|
      send("#{name}=", value)
    end
  end

  def persisted?
    false
 end

end

Controller:

def sendemail    
  @contact = Contact.new(set_params)
  if @contact.valid?
    PageContact.contact_message(@contact).deliver
    flash.notice = "E-mail enviado com sucesso!"
  else
    flash.alert = "* Preencha os campos corretamente."
  end          
  redirect_to root_path
end

private
  def set_params
    params.permit(:name, :email, :subject, :message)
  end

The problem I realized is that you’re not going through validation.

Answer 1

I put it that way and it worked.

@contact         = Contact.new
@contact.name    = params[:name]
@contact.email   = params[:email]
@contact.subject = params[:subject]
@contact.message = params[:message]
if @contact.valid?
  PageContact.contact_message(@contact).deliver
end
