No, I mean the content of a file so if it's a text file then it'll
contain text.
I found this to add to the File class:
contents = db.BlobProperty()
and this when I set it:
file.contents = db.Blob(content)
but when I retrive it from the data store I can't find a way to get
the value.
And for the os like folder and file structure, wouldn't it be better
to store the path of the folder to the data store instead of saving
only the parents key?
because if I would want to get a file with this path:
Folder/Folder 2/File.txt
then I would just search for a file named File.txt with a path "Folder/
Folder 2",
instead of searching for a folder called "Folder" and the searching in
it for a folder named "Folder 2" and then searching in it a file named
"File.txt".
just want your opinion because you all clearly have much more
experience than me with database structure etc.
