undefined local variable or method `default_per_page' for Class Did you mean? default_scope

[deniciocode]

After I updated kaminari I received an error for Mongoid. When I use the kaminari-mongoid gem I have the following issue.

undefined local variable or method 'default_per_page' for Profile:Class Did you mean? default_scope

I updated the version from 0.16.3 to 1.1.1

Interesting. It's the most basic feature of Kaminari and I have no idea how this bug slipped in. Would you mind creating an example app that replicates your issue?

Thanks for reporting!

Hey @yuki24,

I created a new rails project and kaminari works here for mongoid.

I have to dig into my Project where I updated the version of kaminari from 0.16.3 to 1.1.1. Maybe I did not configured it right or something is not loaded inside rails.

If I find something when I will show it.

Thank you for your quick response.

Do I need a specific version for mongoid here? Iam using mongoid version 4.0.2

I am having the same error on Mongoid 4.0.2. I am also upgrading from 0.16.3 to 1.1.1.

Our investigation has shown that Kaminari::ConfigurationMethods is mixed in to our classes per the ancestors method, but the method missing error still happens, when we go into a Pry console and run Foo.send(:include, Kaminari::ConfigurationMethods), then the class method works, although the ancestor list has not changed as far as we can tell.

We are on Rails 4.2.10.

Here's a sample app that exhibits the behavior. It is a stock Rails 4.2.x that has added Mongoid and Kaminari-Mongoid to the gem file. There is one model, Foo. From my pry session:

> Foo.default_per_page
NoMethodError: undefined method `default_per_page' for Foo:Class

> Foo.ancestors
=> [Foo, Mongoid::Document, Kaminari::Mongoid::MongoidExtension::Document, Kaminari::ConfigurationMethods...]

> Foo.send(:include, Kaminari::ConfigurationMethods)
=> Foo
irb(main):004:0> Foo.default_per_page
=> 25

> Foo.ancestors
=> [Foo, Mongoid::Document, Kaminari::Mongoid::MongoidExtension::Document, Kaminari::ConfigurationMethods...]

The ancestor list doesn't change. Is this some kind of load order issue?

[yuki24]

I'm not sure yet but this commit may be it: kaminari/kaminari@4536cc2

[yuki24]

confirmed kaminari/kaminari@4536cc2 broke the integration with mongoid 4.0.

[yuki24]

This issue has been fixed by kaminari/kaminari@d38c684. We'll cut a new release in a few weeks. Thanks!
