Access named scope dynamically
问题 If I have 3 named scopes like class Foo scope :test1, ... scope :test2, ... scope :test3, ... And a function def x(variable) end where variable is a string("test1","test2" or "test3") How can I access the named scope just by knowing that variable's value ? Something like Foo.variable 回答1: You would call Foo.public_send(variable) . 来源： https://stackoverflow.com/questions/15000854/access-named-scope-dynamically
