Hello I am trying to connect with Proteus to make consult to the database and I am having this problem, when I make the consultation. ``` File "/home/hidura/Documents/RESTPOS/clientPOS/app.py", line 23, in hello User_tbl = Model.get('res.user') File "/home/hidura/Documents/RESTPOS/server/TrytonREST/env/lib/python3.7/site-packages/proteus/ __init__.py", line 758, in get class Spam(Model, metaclass=MetaModelFactory(name, config=config)()): File "/home/hidura/Documents/RESTPOS/server/TrytonREST/env/lib/python3.7/site-packages/proteus/ __init__.py", line 466, in __init__ self.config = config or proteus.config.get_config() File "/home/hidura/Documents/RESTPOS/server/TrytonREST/env/lib/python3.7/site-packages/proteus/config.py", line 359, in get_config return _CONFIG.current AttributeError: '_thread._local' object has no attribute 'current' 127.0.0.1 - - [31/Mar/2020 21:43:41] "GET / HTTP/1.1" 500 - ``` This is the config: config = config.set\_trytond(‘sugelico’) If I add the config file, still have the same problem. Thanks in advance. ---

If you are using proteus in a multihread environment, you must set the configuration for each thread and use Model class from the same thread configuration. ---

Ok, so I put the configuration on the same thread that Im going to create the model. ---

Hello I’d been trying to work with proteus but still have a issue, I’ve open a python thread not working via the IDE and the mistake is the lack of the module trytond.backend, but i’ve installed ``` Traceback (most recent call last): File "", line 1, in File "/home/hidura/Documents/RESTPOS/server/TrytonREST/env/lib/python3.7/site-packages/proteus/config.py", line 293, in set_trytond _CONFIG.current = TrytondConfig(database, user, config_file=config_file) File "/home/hidura/Documents/RESTPOS/server/TrytonREST/env/lib/python3.7/site-packages/proteus/config.py", line 244, in __init__ Pool.start() File "/home/hidura/Documents/RESTPOS/server/TrytonREST/env/lib/python3.7/site-packages/trytond/pool.py", line 104, in start register_classes() File "/home/hidura/Documents/RESTPOS/server/TrytonREST/env/lib/python3.7/site-packages/trytond/modules/ __init__.py", line 321, in register_classes import trytond.ir File "/snap/pycharm-professional/192/plugins/python/helpers/pydev/_pydev_bundle/pydev_import_hook.py", line 21, in do_import module = self._system_import(name, *args, **kwargs) File "/home/hidura/Documents/RESTPOS/server/TrytonREST/env/lib/python3.7/site-packages/trytond/ir/ __init__.py", line 4, in from .configuration import * File "/snap/pycharm-professional/192/plugins/python/helpers/pydev/_pydev_bundle/pydev_import_hook.py", line 21, in do_import module = self._system_import(name, *args, **kwargs) File "/home/hidura/Documents/RESTPOS/server/TrytonREST/env/lib/python3.7/site-packages/trytond/ir/configuration.py", line 3, in from ..model import ModelSQL, ModelSingleton, fields File "/snap/pycharm-professional/192/plugins/python/helpers/pydev/_pydev_bundle/pydev_import_hook.py", line 21, in do_import module = self._system_import(name, *args, **kwargs) File "/home/hidura/Documents/RESTPOS/server/TrytonREST/env/lib/python3.7/site-packages/trytond/model/ __init__.py", line 3, in from .model import Model File "/snap/pycharm-professional/192/plugins/python/helpers/pydev/_pydev_bundle/pydev_import_hook.py", line 21, in do_import module = self._system_import(name, *args, **kwargs) File "/home/hidura/Documents/RESTPOS/server/TrytonREST/env/lib/python3.7/site-packages/trytond/model/model.py", line 9, in from trytond.model import fields File "/snap/pycharm-professional/192/plugins/python/helpers/pydev/_pydev_bundle/pydev_import_hook.py", line 21, in do_import module = self._system_import(name, *args, **kwargs) File "/home/hidura/Documents/RESTPOS/server/TrytonREST/env/lib/python3.7/site-packages/trytond/model/fields/ __init__.py", line 4, in from .field import * File "/snap/pycharm-professional/192/plugins/python/helpers/pydev/_pydev_bundle/pydev_import_hook.py", line 21, in do_import module = self._system_import(name, *args, **kwargs) File "/home/hidura/Documents/RESTPOS/server/TrytonREST/env/lib/python3.7/site-packages/trytond/model/fields/field.py", line 21, in Database = backend.get('Database') File "/home/hidura/Documents/RESTPOS/server/TrytonREST/env/lib/python3.7/site-packages/trytond/backend/ __init__.py", line 25, in get module = importlib.import_module(modname) File "/usr/lib/python3.7/importlib/ __init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) ModuleNotFoundError: No module named 'trytond.backend.' ``` This happen when I try to make the config.set\_trytond(‘dbname’, user=‘username’) ---

It seems that you are passing an empty database uri to the tryton server as it uses an empty string for the backend. You should set a valid database uri to fix this error.
