Put something like it in your def call_the_helper:

haml_tag :td, :class => 'center' do
  log.streaming_verification_id
end
haml_tag :td, :class => 'center' do
  log.id
end

Nowadays you may need something like `haml_concat log.id` to render the text, but the general approach is still good. – Arsen7 Nov 15 '18 at 10:58

Simply to do it by moving the code into an other view (partial), and render it from helper or another view.

view:

- @tool_cvt_streaming_verification_logs.each do |log|
  %tr
    = call_the_helper(log)

helper:

def call_the_helper(log)
    render partial: 'partial_view', locals: { :log => log }
end

partial view:

%td.center= log.streaming_verification_id
%td.center= log.id
