Question

I have hierarchical the statements like this

<% @descriptions.each_with_index do |description, i| %>
  <% description.tale2.each do |tax_ref| %>            
    <% if condition %>              
      <% if condition %>
        <% if condition %>                  
          <%= $text_first_describe%> <%= $paren_author_yr %>
             <% ref_sp_uniq.each_with_index do |ref, i| %>
               <% if ref == tax_ref.ref_wo_brace%>
                  <% execution %>                      
               <% elsif i == (ref_sp_uniq.size - 1)%>
                  <%# @ref_desc = "#{@ref_desc_numb}. #{tax_ref.ref_wo_brace}" %>
               <% end %>
             <% end %>
          <% if condition %>
                  <% execution %>                      
          <% elsif condition %>
            <% execution %>
          <% elsif taxon_name.emend_author_year %>                    
             <%= print %>
          <% else %>                    
             <%= print %>                    
          <% end %>
        <% end %>
      <% else %>
        <% if condition %>
          <%= print %>
          <% ref_sp_uniq.each_with_index do |ref, i| %>
             <% if condition %>
                <% execution %>                      
             <% elsif condition %>
                  <% execution %>                      
             <% end %>
          <% end %>
          <% if condition %>
            <% execution %>                      
          <% elsif condition %>
            <% execution %>                      
          <% elsif condition %>
            <% execution %>                      
          <% else %>
            <% execution %>                      
          <% end %>
        <% end %>
      <% end %>
    <% end %>
  <% end %>        
<% end %>

Kindly suggest me possible way to reduce this kind of junk “if statements”.

Answer 1

first of all I would put this code in a helper, so you get rid of all the tags and you clean the view, then look if you can apply the case statement and latter remember maybe you can include line_of_code if condition or condition ? code_a : code_b.

Hard to do something without conditions (I suppose the condition change each if), why not to address the question to https://codereview.stackexchange.com/
