Description

Now, where(undefined_key: nil) returns all records.
But I think where(undefined_key: nil) should raise an error because

  • It's same as ActiveRecord behavior.
  • We cannot recognize typo and get a surprising result.

Code to reproduce

class Records < ActiveHash::Base
  self.data = [
    { id: 1, name: 'foo' },
    { id: 2, name: 'bar' },
    { id: 3, name: 'baz' }
  ]
end

pp Records.where(undefined_key: nil).to_a
# [
#    #<Records:0x00007fadaf51a5e0 @attributes={:id=>1, :name=>"foo"}>,
#    #<Records:0x00007fadaf519988 @attributes={:id=>2, :name=>"bar"}>,
#   #<Records:0x00007fadaf519348 @attributes={:id=>3, :name=>"baz"}>
# ]
