I want the external method to return this in a list, where I can iterate over using the <dtml-in> tag, so that I can reference the different fields in each record with a name.
What should the list look like so that I can accomplish this?
dtml-in eats a list of objects or a list of dictionaries.
I usually use the following helper-class: class generic_datarecord: " This class provides an overall mapping of value pairs " def __init__(self,**data): self.data=data def __len__(self): return(len(self.data.keys())) def __getitem__(self,key): return(self.data[key]) def __getattr__(self,key): return self.__getitem__(key) def keys(self): return(self.data.keys()) def values(self): return(self.data.values()) if you use generic_datarecord(column1=value1,coulumn2=value2) for each row, you can alterate over a list of such datarecord_objects with <dtml-in> using <dtml-var column1> and <dtml-var column2> HTH Tino Wildenhain PS: __len__() is optional, but for easy use in all circumstances (e.g. <dtml-in> over a single datarecord)
