Massimo, Further debugging I learnt that the derived Adapter classes like MySQLAdapter (and several others) call a method call "find_or_make_folder"
MongoDBAdapter does *not* call find_or_make_folder() - hence the self.folder remains None till the point it needs to be used. *Is there a specific reason why databases folder is not required for Mongo ?* (I saw that databases folder for mysql project has sql.log containin several SQL commands - I couldn't make sense of other files under there) Is there a way to have a default uploadfolder value for MongoDBAdapter ? (I know I can pass it as an argument to DAL - but that is NOT default, that is user supplied) -Mandar On Wednesday, March 26, 2014 10:32:27 PM UTC+5:30, Mandar Vaze wrote: > > I think this might be a false alarm on my part. > In another project I used mysql - where ( I assume) self._adapter.folder > is set - so default value is assigned within DAL code. > My current project uses mongoDB - hence it is possible that for mongoDB > adapter doesn't set the .folder value - hence the error. > > That begs a question - should mongodb set the adapter.folder value ? > > From the code it doesn't look like DB specific behaviour > > -Mandar > > > On Wednesday, March 26, 2014 6:34:06 PM UTC+5:30, Mandar Vaze wrote: >> >> Documentation ( >> http://www.web2py.com/books/default/chapter/29/06/the-database-abstraction-layer#Field-types) >> >> says >> "uploadfolder defaults to the application's "uploads/" folder." >> >> Yet, the code (web2py™ Version 2.9.4-stable+timestamp.2014.03.05.04.44.09) >> defaults to "None" resulting into following error : >> >> /path/do/web2py/gluon/dal.py", line 9953, in store >> "you must specify a Field(...,uploadfolder=...)") >> >> am I doing something wrong ?
