Hi, Thanks for the help. I had too much to work on, so I left the problem for the time. Now I am back working on blobstore module.
I was looking at the code in web2py slices and in other threads in the group and got confused again. I think the problem is too many versions/parts of the code here and there. Like on web2pyslices itself, there are 3 versions, the slice itself and the code in the comments. Now assuming the latest comment is the updated code, I find many things different from the code of the slice and very less documentation/changelog on it. I tried running the code in the latest comment but could not get it working. I hope you understand my problem. I would really appreciate if somebody could compile the code (which would include the DB structure, the controller methods and the view) at one place, a new slice maybe. Thanks.
