ruby on rails - Format Active Record Data before rendering as JSON -
i have data table going convert ajax , have format json values right formats.
in example how format tables.created_at time-stamp mm/dd format...
tables = table.where(:state => "missouri") respond_to |format| format.json { render json: tables } end in dom loop through data , needed it: chronic.parse(s.created_at.to_date).strftime("%m/%d")
and can see have alot of additional formatting data before returned json:
<% if @load_search.nil? %> <tr></tr> <% else %> <% @load_search.each |s| %> <tr id="row_<%= s.id %>"> <td align="center"> <%= s.id %> </td> <td class="count" align="center"> <%= s.results %> </td> <td align="center"> <%= chronic.parse(s.created_at.to_date).strftime("%m/%d") %> </td> <td align="center"> <% if s.equipment.empty? %> equipment <% else %> <%= s.equipment.pluck(:code).to_s.gsub("[","").gsub(']','').gsub('"','') %> <% end %> </td> <td align="center"> <% if s.origin_id.nil? %> <%= s.origin_states %> <% else %> <%= location.find(s.origin_id).cs unless s.origin_id.nil? %> <% end %> </td> <td align="center"> <%= s.origin_radius_cs %> </td> <td align="center"> <% if s.dest_id.nil? %> <%= s.dest_states %> <% else %> <%= location.find(s.dest_id).cs unless s.dest_id.nil? %> <% end %> </td> <td align="center"> <%= s.dest_radius_cs %> </td> <td align="center"> <%= s.length.to_s + ' ft.' unless s.length.nil? %> </td> <td align="center"> <%= s.weight.to_s + ',000 lbs' unless s.weight.nil? %> </td> <td align="center"> <% if s.ltl %> partial <% elsif s.both %> full <% else %> both <% end %> </td> <td align="center"> <%= chronic.parse(s.pickup.to_date).strftime("%m/%d") %> </td> <td align="center"> <%= chronic.parse(s.delivery.to_date).strftime("%m/%d") unless s.delivery.nil?%> </td> </tr> <% end %> <% end %>
you can override activerecord getter as
class model def created_at self[:created_at].strftime("%m/%d") end end
