Rails 3.1.3 & # 8594; 3.2.1 Error

Question

My application has been running 3.1.x for some time now. He is currently running 3.1.3. I tried to switch to 3.2.1; however, every time I make a db request, I get the following error:

NoMethodError: undefined method `synchronize' for nil:NilClass 

This happens with any queries with an active record, such as User.first, User.all, User.find (1), etc. I tried using several versions of the sqlite3 stone in development to make sure this was a problem, but I was out of luck. The version I tried was 1.3.5 w / Rails 3.2.1.

Answer 1

try updating the gem "kaminari" from "0.12.4" to "0.13.0"
