Hello,
I am trying to use PyDAL from a Python 3 script. I pip installed it without
issue but when attempting to open up an existing database (created with
web2py running on Python 2.6) I get the following error:
form pydal import DAL
db = DAL('sqlite://sqlite.db', folder=db_path, auto_import=True)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python3.5/site-packages/pydal/base.py", line 174, in
__call__
obj = super(MetaDAL, cls).__call__(*args, **kwargs)
File "/usr/local/lib/python3.5/site-packages/pydal/base.py", line 496, in
__init__
tables=tables)
File "/usr/local/lib/python3.5/site-packages/pydal/base.py", line 512, in
import_table_definitions
sql_fields = pickle.load(tfile)
TypeError: a bytes-like object is required, not 'str'
Which I can trace to these line of source code
for filename in glob.glob(pattern):
tfile = self._adapter.file_open(filename, 'r')
try:
sql_fields = pickle.load(tfile)
I believe tfile must be opened in 'rb' mode in Python 3. Is there a
workaround so I can get this working? I have other needs that require
Python 3 over Python 2.
Thanks
