Custom matcher for ActiveHash. It provides like operator.
After install ActiveHash::Like, you can use like method.
class Country < ActiveHash::Base; end
Country.like(name: 'Cana%')If you want to use like in the where method parameter, you can use ActiveHash::Matcher::Like matcher.
# Specify match type.
Country.where(name: ActiveHash::Matcher::Like.new('Cana%'))
# Or use forward, backward, partial method.
Country.where(name: ActiveHash::Matcher::Like.forward('Cana'))ActiveHash::Matcher::Like is one of custom matcher. You can create your custom matcher.
It should have call method like the following:
class MyCustomMatcher
attr_accessor :pattern
def initialize(pattern)
self.pattern = pattern
end
def call(value)
# Case ignore matcher
value.upcase == pattern.upcase
end
end
Country.where(name: MyCustomMatcher.new('pattern'))So, you can use Proc object as simple custom matcher.
Country.where(name: ->(value){ value == 'some value'})you can use key: or like the following:
Country.where(name: 'Canada', or: {field1: 'foo', field2: 'bar'})
#=> name = 'Canada' and (field1 = 'foo' or field2 = 'bar')If you want to use or to one column, you must use custom matcher.
Country.where(name: ->(val){val == 'Canada' || val == 'US'})Add this line to your application's Gemfile:
