scope override errore when used with sublcasses

[saten]

Hello,

our app has a class which includes Mongoid::Document and many subclasses. the following exception is thrown Mongoid::Errors::ScopeOverwrite when kaminari-mongoid attempts to add page scope to each of the subclasses (file mongoid_extensions:12)

mongoid 4.0.2 kaminari master kaminari-mongoid master

Could you provide an example app or a test case that replicates your issue?

[saten]

in theory you could replicate it easily doing the following

class Parent include Mongoid::Document end

class Child < Parent end

class OtherChild < Parent end

it should throw the exception when loading the file of the child class

We have the exact same setup in the test and the build for Mongod 4.0 is green (I just re-ran just in case.) This is why we almost always ask for a test case or an example app that's actually runnable instead of a code snippet that doesn't necessarily replicates the issue.

Also, please use markdown to make your comments more readable. Plain text is very hard to read.

i'll try to reproduce it in a separate app. sorry for plain text, i'm replying by mail :(

Hi, could not reproduce the exact behaviour, which I believe is tied to mongoid version.

The following repo is a brand new rails 4.1.x app with mongoid 4.0.2 and kaminari-mongoid

Try creating a Person::Individual record

Your example app seems to be working fine after applying the following diff:
