Please quote the previous message when replying as this is actually a mailing list not a forum, though you may be accessing it using a forum-like interface. My reply was:

You need to show us the exact error and the line of code it is failing on (with the lines around it). First, though, have a look at the Rails Guide on Debugging which will show you techniques that you can use to debug your code.

Thanks for you replying Colin:

Look, this's my message of error:

NoMethodError in MallacurricularesController#create undefined method `save' for :ActiveRecord::Relation

Parameters: {"utf8"=>"✓", "authenticity_token"=>"CEX4yZeFmrSOspseMm2/d8rzPzu/3FYI2w8d7XZ1Ji0=", "malla"=>{"clase_id"=>"1", "subjects_ids"=>["3", "4", "5"]}, "level"=>"3", "commit"=>"GUARDAR"}

The parameters looks good, and my controller is:

  def new     @asignatura = Asignatura.find(:all)     @clase = Clase.find(:all)     @nivel = Nivel.find(:all)     @malla = Malla.new   end

def create      @malla = Malla.new(params[:malla])      @subject = @malla.subjects(params[:subject_ids])      @level = @malla.levels(params[:level])

       if @malla.save and @subject.save and @level.save        redirect_to mallacurriculares_menu_principal_admin_path, :notice => 'MALLA created'        end   end

In my controller i want to save the "ids" that i chose in the view form to my model: subject_malla_level.

And i dont know how to do it, please help men :frowning:
