undefined method `paginate' for #<Class:0x567eb98> in Rails Tutorial
Hi,
I''m getting a undefined method `paginate'' for #<Class:0x567eb98> even
though I have gem ''will_paginate'' installed.
Inside the users_controller I have @users = User.paginate(page: params[:page
])
so I believe I set everything up to be correct.
Can you figure out why the method''s undefined, despite installing the gem?

attr_accessible on some properties + attr_protected on others makes class 'open-by-default'
(I posted this as a bug in GitHub
(https://github.com/rails/rails/issues/7018), but then someone there told
me I should post it here, so here it is.)
If you set attr_accessible on some properties in an ActiveRecord-descended
class, and then attr_protected on others - the class becomes ''default-open''
- if any properties are missed or added later, they will be accessible by

Optimistic Locking Enhancements: Gem or Core?
I''m working on an app that makes use of rails'' optimistic locking feature
and seeing some possibilities for improvements. It seems a bit tedious to
have to add :lock_version to forms wherever the model is used. You also
have to "hack" around rails'' UJS feature to add it as a URL parameter when
using remote: true, method: [:put, :patch, :post, :delete].

Is there planned support for permitting params one at a time vs. all at once in strong_parameters/Rails 4?
Was going to have a variety of request params sent in and use a
class_attribute that would define types of request parameters that are
allowed. strong_parameters wouldn''t be too much trouble in such a case if
it would allow me to manually permit some attributes (dynamically
determined) in the controller but allow strong_parameters to enforce
security of others.

Getting started w/ Rails 4
