Hello folks !
I have database that's have BLOB type to store any kind of data (it's
should be binary ?):
Field('f_blob', type='blob',
label=T('blob object')),
I'm inserting new records with:
db.t_cache.insert(f_name='processed_' + request.vars.filename, f_blob= data)
Where data is pandas object which is covnerted to CSV:
data = StringIO.StringIO()
source.to_csv(_tmp_data)
data.seek(0)
In database DATA record appears. but i can't fnd any information about
retrieving this object from db.
I tried RETRIEVE method (where the hell documenation about this ? no comments
in source)
Such as:
db.t_cache.f_blob.retrieve(db.t_cache[ID].f_blob).f_blob gives =
{TypeError}Can't retrieve <StringIO.StringIO instance at 0x03BD95A8> file
properties
db.t_cache.f_blob.retrieve(db.t_cache[ID]) = {TypeError}expected string or
buffer
So how to get back BLOB object from databse and use it later ?
