If you're using `protected_attributes` gem and would like to smoothly switch over to `strong_params`, this is a possible useful monkey patch to only use the mass assignment protection when handling controller params.
# Not fully tested, use at own risk!
module ActiveModel
module MassAssignmentSecurity

Last active January 23, 2017 12:11
When you really want to test a private method, you can use this simple helper to temporarily expose it for easier access during specs.
require "spec_helper"
RSpec.describe MyClass do
describe "#some_private_method" do
expose_method MyClass, :some_private_method
it "works" do
MyClass.new.some_private_method
end
end

dv / better_travel_to.rb
Created October 20, 2018 15:02
This circumvents the no-nesting rule of the new `travel_to` in Rails TimeHelpers
# The new `travel_to` does not allow nested calls, and instead throws the following error
# in your face whenever you try to use it:
#
# Calling `travel_to` with a block, when we have previously already made a call to `travel_to`, can lead to confusing time stubbing.
#
# Using this module to override `travel_to` will solve that issue.
#
# Note: not guaranteed to work perfectly
