It wraps the  incoming list and dict structures so that the GET url used on the links can handle the nested structures. A colleague of my has a version that is recursive. The code here only goes a level deep. It was needed to pass form data along with the pagination. It's taken from Randall's patch for pagination. Look at http://trac.turbogears.org/turbogears/ticket/1115 for more. ...         # If we have a nested dict from a form, it must be denormalized before         # it can be put into a GET URL.         #     {'form_field':{'text':'hello', 'hidden':''}         # Goes to:         #     {'form_field.text':'hello', 'form_field.hidden':''}         # I'm going to be specific so as to minimize breakage.         #         #  -- Nicky's change. Break out lists like Randall did for dicts.         for (ikey, ivalue) in input_values.items():             if isinstance(ivalue, dict) and len(ivalue) > 1:                 del input_values[ikey]                 for (sub_ikey, sub_ivalue) in ivalue.items():                     if isinstance(sub_ivalue, list) and len(ivalue) > 1 :                         for idx, sub_sub_ivalue in enumerate (sub_ivalue):                             new_key ='%s.%s-%d' % (ikey,sub_ikey,idx) # Magic list format                             input_values[new_key] = sub_sub_ivalue                     else:                         new_key = '%s.%s' % (ikey, sub_ikey)                         input_values[new_key] = sub_ivalue # This is probable needed for completeness...             if isinstance(ivalue, list) and len(ivalue) > 1 :                 for idx, sub_ivalue in enumerate (ivalue):                     new_key ='%s-%d' % (ikey,idx) # Magic list format                     input_values[new_key] = sub_ivalue I'd strongly suggest using formencode.variabledecode.variable_encode for encoding the data NestedVariables decodes (using formencode.variabledecode.variable_decode) from the request parameters in TG's filter.  Just in case one day this encoding format changes in FE (and to avoid wheel reinvention ;) ) Alberto --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "TurboGears" group.
