Ruby on Rails

I don't know if this is an acceptable practice, but I do the following on update... and it works for me

def update

unless params[:id].blank?
unless params[:parent_object].blank?

   @p_o_hold = @parent_object.find(params[id])
   unless @p_o_hold.blank?
    myupdatehash = Hash.new
    /////  Then I select from params[:parent_object] that I need and apply some validation or database format requirements
       myupdatehash = [:field => ...., ]
    if @p_o_hold.update_attributes(myupdatehash[0])   
        @child_object = ChildObject.find(@p_o_hold.id)
         unless  @child_object.blank?
            myupdatehash = [:child_field => @p_o_hold.child_field_value]  ## hash object reuse
                @child_object.update_attributes(myupdatehash[0])

.....
