如果params存在，Rails重构link_to

Question

我使用Rails 5.1并拥有此代码段。 我怎样才能重构它以使其更具可读性？

在views / imagecapturings / index.html.erb

中

<% if params.has_key?(:select) %>
<%= link_to 'St. Gallen', digitized_in_stgallen_imagecapturings_path('select[year]' => params[:select][:year], 'select[month]' => params[:select][:month]) %>
<% else %>
<%= link_to 'St. Gallen', action: "digitized_in_stgallen", method: :get %>
<% end %>

Answer 1

您可以使用三元运算符

<%= params.has_key?(:select) ?
    link_to('St. Gallen', digitized_in_stgallen_imagecapturings_path('select[year]' => params[:select][:year], 'select[month]' => params[:select][:month])) :    
    link_to('St. Gallen', action: "digitized_in_stgallen", method: :get) %>
