I have been trying for a while to get arguments passed to a ZSQL Method from inside a dtml-in loop. My top level objective is to update a table with multiple changes to date/times and descriptions in records about conference sessions input from a form. Having read many posts here and other documentation, my current attempt should work, but I can't get it right yet. I keep getting a TypeError in the DateTime function indicating that the date isn't being passed in the format I think it should be: Here is the dtml I am trying: (The relevant fields in the table are: ID,StartsAt,aDescription) <dtml-var standard_html_header> <dtml-if expr="REQUEST.has_key('submit')"> <dtml-in s> <dtml-call expr="sessions_modifydates(_)"> </dtml-in> </dtml-if> <form method=post action=sessions_update> <table> <dtml-in sessions_list> <tr><td> <input type=text name=s.ID:records value=<dtml-var ID> size=4> </td><td> <input type=text name=s.StartsAt:records:date value="<dtml-var StartsAt>"> </td><td> <input type=text name=s.aDescription:records value="<dtml-var aDescription>" size=60> </td><tr> </dtml-in> </table> <input type=submit name=submit> </form> <dtml-var standard_html_footer> The (not very well named) ZSQL Method sessions_modifydates is as follows. If it gets a date that DateTime can recognize, it converts it to SQL format: UPDATE tblSession SET tblSession.StartsAt = <dtml-var expr="_.DateTime(StartsAt).strftime('#%m/%d/%Y %H:%M:%S#')">, tblSession.Description = <dtml-sqlvar aDescription type=string> <dtml-sqlgroup where> <dtml-sqltest ID op=eq type=int> <dtml-and> <dtml-sqltest ConferenceID op=eq type=int> </dtml-sqlgroup> (Note that commenting out the updating of the date then allows the description to be updated, so I think everything else works OK. I use 'aDescription' because I thought Description may have been a reserved word somewhere along the line, but it probably isn't.) For completeness, here is the traceback I get: Traceback (innermost last): File C:\Programmer\WebSite\lib\python\ZPublisher\Publish.py, line 150, in publish_module File C:\Programmer\WebSite\lib\python\ZPublisher\Publish.py, line 114, in publish File C:\Programmer\WebSite\lib\python\Zope\__init__.py, line 158, in zpublisher_exception_hook (Object: sss) File C:\Programmer\WebSite\lib\python\ZPublisher\Publish.py, line 98, in publish File C:\Programmer\WebSite\lib\python\ZPublisher\mapply.py, line 88, in mapply (Object: sessions_update) File C:\Programmer\WebSite\lib\python\ZPublisher\Publish.py, line 39, in call_object (Object: sessions_update) File C:\Programmer\WebSite\lib\python\OFS\DTMLMethod.py, line 127, in __call__ (Object: sessions_update) File C:\Programmer\WebSite\lib\python\DocumentTemplate\DT_String.py, line 473, in __call__ (Object: sessions_update) File C:\Programmer\WebSite\lib\python\DocumentTemplate\DT_In.py, line 695, in renderwob (Object: s) File C:\Programmer\WebSite\lib\python\DocumentTemplate\DT_Util.py, line 159, in eval (Object: sessions_modifydates(StartsAt=_['sequence-var- StartsAt'])) (Info: _) File <string>, line 2, in f File C:\Programmer\WebSite\lib\python\Shared\DC\ZRDB\DA.py, line 414, in __call__ (Object: sessions_modifydates) File C:\Programmer\WebSite\lib\python\DocumentTemplate\DT_String.py, line 473, in __call__ (Object: <string>) File C:\Programmer\WebSite\lib\python\DocumentTemplate\DT_Util.py, line 159, in eval (Object: _.DateTime(StartsAt).strftime('#%m/%d/%Y %H:%M:%S#')) (Info: StartsAt) File <string>, line 2, in f File C:\Programmer\WebSite\lib\python\DateTime\DateTime.py, line 671, in __init__ File C:\Programmer\WebSite\lib\python\DateTime\DateTime.py, line 279, in _calcSD TypeError: (see above) Thanks in advance for any advice.
