Answer 1

You cannot call both render and redirect_to. That is what you have done (calling redirect_to inside the render block.

To redirect in some cases, you will need to move the if condition outside the render block. Try something like this:

if I_need_to_redirect
  item_link = params[:controller].eql?("compliance_items") ? edit_compliance_compliance_item_path(master, @master_item) : edit_controls_item_path(@master_item)
  redirect_to item_link
else
  responds_to_parent do
    render :update do |page|
      page << "tb_remove"
    end
  end
end

Where I_need_to_redirect should be replaced with the condition for checking whether you should redirect (if false, it should render instead).
