This extension is usesd in order to expose the object of the implementing class to liquid as it were a Drop. It also limits the liquid-callable methods of the instance to the allowed method passed with the liquid_methods call Example:
class SomeClass
liquid_methods :an_allowed_method def an_allowed_method 'this comes from an allowed method' end def unallowed_method 'this will never be an output' end
end
if you want to extend the drop to other methods you can defines more methods in the class <YourClass>::LiquidDropClass
class SomeClass::LiquidDropClass def another_allowed_method 'and this from another allowed method' end end
end
usage: @something = SomeClass.new
template: {{something.an_allowed_method}}{{something.unallowed_method}} {{something.another_allowed_method}}
output: ‘this comes from an allowed method and this from another allowed method‘
You can also chain associations, by adding the liquid_method call in the association models.
