WiceGrid 3.6.0.pre4 examples

Custom filters (method chains)

An array of symbols submitted to :custom_filter has a special meaning. The first symbol is sent as a method name to EVERY ActiveRecord object. If an object responds to this method, the second method name is sent to the returned value unless it is nil, and so on. The dropdown is populated by the list unique values. The conditions set up by the user are ignored, that is, the records used are all those found on all pages without any active filters. Naturally this can be extremely inneffective and should be used with caution.
