Ruby on Rails - value printed correctly in log but not in view -

i'm trying fetch value via controller , prints correctly in logs. however, when print in view gives error.

controller:

@leads = lead.all.order('updated_at desc')     @leads.each |k|       if k.lead_propertiesproperty_id = k.lead_properties.map(&:property_id)         properties = property.where(:id => property_id)         category_ids = properties.map(&:property_category_id)         categories = propertycategory.where(:id => category_ids)         @category_names = categories.map(&:name).exists?          rails.logger.debug("categories: #{categories.inspect}")         rails.logger.debug("category_names: #{@category_names.inspect}")       else         @properties = "no properties"         @locations = "no locations"       end     end     @leads_total = lead.all.count 

view:

  <tbody>     <% @leads.each |lead| %>     <tr class="<%=cycle('odd', 'even') %> location_row" id="lead_row" data-id="<%= lead.id%>">       <td><%= lead.id %></td>       <td><%= lead.fullname %></td>       <td><%= lead.email %></td>       <td><%= lead.phone %></td>       <td><%= @category_names.to_sentence %></td>       <td><%= select_tag :status, options_for_select(lead.statuses.keys.to_a{|k, v| [k.humanize.capitalize, v]}, lead.status), :class => "lead_status"%></td>       <td><%= lead.created_at.strftime("%d %b. %y - %t")%></td>       <td><%= link_to (fa_icon "pencil-square-o "), edit_lead_path({:id => lead.id, :first_last_name => lead.first_last_name}), :title => 'edit lead', :class => "action-button" %></td>     </tr>     <% end %>   </tbody> 

the error: in controller log gives correct category (eg. desk, virtual, private) value each lead in view gives category value last lead, every lead.

if understand correctly it's because @category_names being assigned in loop.

so example if first time loop runs category "desk" @category_names becomes "desk"

however second time runs category becomes "virtual" overwrites @category_name variable.

you need push category_names hash id of lead

@category_names = {}  @lead.each |lead|    if lead.category_name.is_what_i_want?      @category_names[lead.id.to_s] = lead.category_names     end   end 

very pseudo should

then in view

@category_names[lead.id.to_s].to_sentence
