Re: [Zope] Question about dtml-in
Sean McGrath wrote: Hello all, I have a question about the dtml-in tag. When it is iterating over a sequence, and the items in the sequence happen to be tuples containing exactly two items, then dtml-in places the first item from the sequence in sequence-key, and the second item goes in sequence-item. If the items in the sequence are not tuples of two items, then sequence-item contains the whole item. For example, if I have: dtml-in "[(1,2),(3,4),(5,6)]" dtml-var sequence-item /dtml-in then I get 2,4,6 when I view this. The 1, 3 and 5 have been assigned to sequence-key. Now, if I change the dtml to be this: dtml-in "[(1,2,3),(3,4,5),(5,6,7)]" dtml-var sequence-item /dtml-in then I get (1,2,3)(3,4,5)(5,6,7) which is what I would expect. I think the reason for this behaviour is to do with iterating over dictionaries, but I'm not sure. The problem I have is this: I have code which retrieves data from a database, and the result is a list of tuples, with each tuple corresponding to a record, and each item in the tuple corresponding to a field. I don't know in advance how many fields will be in the record. I want to iterate over the records and fields, wrapping them in a html table. If the database I'm talking to happens to return a list of records with two fields, ie a tuple of two items, I have to handle this differently than any other case, which makes for some ugly code. I haven't been able to find any way to avoid this, unless I'm missing something. Any information would be greatly appreciated. Regards, in addition to Dieter Maurer's suggestion of fixing this behavior in dtml-in, another possibility is to do the work in a web python method, and directly access the Result object from the query to generate the html.

Well, I found there _is_ a reverse attribute to the dtml-in tag, but it's not documented in my version (2.1.0, 1999/12/17) of the DTML Reference. It works.
