Hello,  
I also have same problem. but i fix it by making patch in  
lib/connected.rb of magic\_multi\_connections gem.

replace

raise NameError.new ( “uninitialized constant # (const\_id)”) unless  
target\_class target\_class

with

return unless target\_class

try this out, it’s solved your problem.
