model - Rails TypeError when passing a object -

i creating tableless model in rails 4 supporting sending emails easily.

so have following model:

class message   include activemodel::model    attr_accessor :subject, :content, :email end 

the following controller:

class messagescontroller < applicationcontroller   def new     @message = message.new   end   def create    message = message.new(params[:message])    if message.valid?      usermailer.send(message)      redirect_to :back, :notice => "email sent."    else      flash[:alert] = "you must fill fields."      render 'new'    end  end end 

the form:

<%= form_for @message |f| %>   <%= f.label :email %>   <%= f.text_field :email %>    <%= f.label :subject %>   <%= f.text_field :subject %>    <%= f.label :content %>   <%= f.text_area :content, rows: 5, class: 'span7' %>   <%= f.submit "send email", class: 'btn btn-primary' %>  <% end %> 

but when try send email here got:

#<message:0x007fcc98e8c760 @errors=#    <activemodel::errors:0x007fcc98e96788 @base=#<message:0x007fcc98e8c760 ...>, @messages={}>,     @email="sdsadas@adasdas.com", @subject="adasdas", @content="asdsad", @validation_context=nil> not symbol 

the error says in here usermailer.send(message)

can me?

the kernel.send method you're calling on usermailer accepts symbol or string, whereas you're attempting pass instance of message. you're looking other method of usermailer. you'll defining , calling own method on actionmailer::base subclass. see the guide details.
