Subject: Getting wrong id

I have the follow method:

def concluir
    @subtarefa = Subtarefa.find(params[:id])
    @subtarefa.situacao_subtarefa = "Conclu鱈da"
    @subtarefa.data_termino_real = Date.current
    @subtarefa.update_attributes(params[:subtarefa])

    @subtarefas = Subtarefa.find(:all, :conditions =>
["situacao_subtarefa = ? AND tarefa_id = ?", "Conclu鱈da",
@subtarefa.tarefa_id])
    @tarefa = Tarefa.find(:first, :conditions => ["id = ?",
@subtarefa.tarefa_id])
    num = (@tarefa.numero_previsto_subtarefas).to_i
    if @subtarefas.size == num
      @tarefa.situacao_tarefa = "Conclu鱈da"
      @tarefa.data_conclusao = Date.current
    @tarefa.update_attributes(params[:tarefa])

    @tarefas = Tarefa.find(:all, :conditions => ["situacao_tarefa = ?
AND projeto_id = ?", "Conclu鱈da", @tarefa.projeto_id])
    @projeto = Projeto.find(:first, :conditions => ["id = ?",
@tarefa.projeto_id])
    num2 = (@projeto.numero_previsto_tarefas).to_i
    if @tarefas.size == num2
      @projeto.situacao_do_projeto = "Conclu鱈do"
      @projeto.data_conclusao = Date.current
      @projeto.update_attributes(params[:projeto])
    end
    end
        render :action => "show"
        flash[:msg] = "Subtarefa conclu鱈da com sucesso"
  end


My problem is:

undefined method `projeto' for nil:NilClass

It gets the subtarefa's id instead of tarefa's id when i'm loking for a
tarefa in Tarefa class.
If it don't get any tarefa with the subtarefa's id (and it shouldn't,
'cause isn't the right id), @tarefa will be a nil object, haven't, that
way, the "projeto_id" method.

What am i missing?
