I'm hitting a brick wall when trying to convert my table (under PostgreSQL)
to use "blob" storage. The problem seems to be that web2py doesn't
properly recognize and initialize the blob field. For example, when I
tried this:
db.define_table("fileobject",
Field("upload_data","blob"),
Field("upload","upload",uploadfield='upload_data'),
...
The code fails when uploading the blob. In the DAL, in the code for
Field.store():
self_uploadfield = self.uploadfield
if isinstance(self_uploadfield,Field):
blob_uploadfield_name = self_uploadfield.uploadfield
keys={self_uploadfield.name: newfilename,
blob_uploadfield_name: file.read()}
self_uploadfield.table.insert(**keys)
...
In this case, the test to see if self_uploadfield is a Field FAILS --
because the uploadfield still has the string "upload_data", not the
corresponding Field.
Next, I thought I'd try the old-school way, I put the Field definition as
the argument to uploadfield:
db.define_table("fileobject",
Field("upload","upload",uploadfield=Field("upload_data","blob")),
...
Again, this FAILS, but for a different reason -- the "table" attribute of
the "upload_data" table never got initialized to "fileobject"!
I just can't find a way around this. I'm using web2py version 2.5.1-stable
under OSX (running from source).
