Rubymotion multilevel BW::HTTP calls return early -

i attempting call method, from_server, giving block accept results. from_server loads list of items api each in list calls function add_update giving block accept results each detail. when of details have been handled, from_server calls block return summary.

i can low levels work ok. problem first function calls block before done.

not sure why or need put block.call

the main caller

from_server |updates, inserts|   puts "\n  updates = #{updates}"   puts "  inserts = #{inserts}\n\n"   puts 'all done' end 

the from_server function calles

def from_server(&block)   inserts = 0   updates = 0   channels = [1,2,4,6,7]   channels.each     add_update("/api/channels/#{channel}", &block) |added, channel|       if added         inserts += 1       else         updates += 1       end       #do things channel     end     block.call(updates, inserts) unless block.nil? # problem here gets returned channels have been started on thread   end end 

gets list , processes each item

def from_server(&block)   uri = '/api/channels'   apirequest.get(uri) |header, body|     new_count = 0     update_count = 0     puts "\nlist body = #{body}\n"     body.each |channel|       add_update(channel['uri']) |new, ad_channel|         if new           puts "\nnew #{ad_channel}"           new_count += 1         else           puts "\nupdate #{ad_channel}"           update_count += 1         end         puts       end     end     puts "\ndone\n"     block.call(update_count, new_count) unless block.nil?     puts "all requests done\n"   end   puts "request channels started" end 

processes each item

def add_update(channel_uri, &block)   apirequest.get(channel_uri) |header, body|     if ad_channel = advchannel.find(name: body['name']).first       puts "\n#{ad_channel.name} exists"       new = false     else       ad_channel = advchannel.create(name: body['name'],                                      phone: body['phone'],                                      url: body['uri'],                                      admin_url: body['admin_url'],                                      channel_code: body['channel_code'],                                      uri: channel_uri)       puts "\ninserting #{ad_channel.name} - #{ad_channel.id}"       new = true     end     block.call(new, ad_channel)  if block_given?   end 

the results executing caller are: give me following:

request channels started  (expected) list body string (expected) add update 1 started (expected)  done  (unexpected should after done)   updates = 0  (unexpected should after done)   inserts = 0   (unexpected should after done) done   (unexpected should after done) requested done (unexpected should after done)  insert or update information each channel (expected) 

how summary after complete?
