Attribute accessor with a datatype

Question

I am looking to set an attribute_accessor with a datatype associated with it like how we have fields in the model that have database that have datatypes like string , integer etc associated with them.

How do i tell rails that my attr_accessor should respond to a specific datatype. I am looking to set a datetime to one the accessor i am trying to create,

Please suggest.

Answer 1

You can make a custom setter like

def field_name=(value)
  # check for type and dont assign it if its the wrong typ
  # or raise an error
end

just off of the top of my head
