I have a project that uses BinaryFields to pickle dynamic data.
Last week when migrating from sqlite to mysql
using MySQL-for-Python-3 the BinaryField now gets
retrieved as 'str'.
Reading the docs about BinaryField it says it is stored as 'bytes'.
I know mysql stores blobs
as text (right?) but in that case the problem is django's
documentation.
In this particular case:
the attribute mymodel.myblob looked like: b'dadadadaa'
but type(mymodel.myblob) said it was a 'str'
(I'm bit outdated about latest python changes in strings, bytes
and unicode)
Anyways I had to bypass this different behaviour to act just
like the embedded sqlite driver. My 'solution' is not nice:
* I had to reparse the string to make it a 'bytes':
>>> self._tags = eval('b"'+self.tags[2:-1]+'"')
* And add proxy points to get and set the blob
