content_tag

content_tagはのちに消える説あるけどコードが冗長だったので修正しました。

修正前

<% if @provider.key == "noe-jx-group" %>
  <div class="e__saving"><span class="e__tag">割引額</span><span class="e__number e__deals"><%= service['discount'].to_f %></span>円<% if SetPlan.is_discount_from_energy?(service) %>/kWh<% elsif SetPlan.monthly?(service) %>/月<% elsif SetPlan.yearly?(service) %>/年<% end %></div>
<% end %>

修正後

<%= discount_text(service, @provider) %>

try_helper.rb

  def discount_text(service, provider)
    content_tag(:div, class: "e__saving") do
      discount_text = content_tag(:span, "割引額", class: "e__tag")
      discount_value = content_tag(:span, provider.key == "noe-jx-group" ? service['discount'].to_f : service['discount'].to_i, class: "e__number e__deals" ) + "円"
      discount_from_energy = if SetPlan.is_discount_from_energy?(service)
        "/kWh"
      elsif SetPlan.yearly?(service)
        "/年"
      elsif SetPlan.monthly?(service)
        "/月"
      end
      discount_text + discount_value + discount_from_energy
    end
  end
