[tryton] Proteus

This

$ python
Python 2.7.14 (default, Sep 17 2017, 18:50:44)
[GCC 7.2.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.

from proteus import config, Model

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named proteus
Of course Proteus is installed with apt-get

This is more of a Debian/Python question than Tryton
Please bear with me

I'd like to use Proteus to debug one of my calculated fields, that's not working

Currently I have to reload the whole client and log in again every time I change something

Thanks

[FREDY RAMIREZ]

Hi,

You can download Proteus from tryton download page and set PYTHONPATH with your proteus path.

Hope this help.

I guess you are not using the right Python for which proteus was
installed.
Maybe you are under a virtualenv, in this case you should install
proteus using `$ pip install proteus`.

Thank you people

No, I' m not using virtualenv.

But I found a couple of facts.

When called from within a python3 prompt, Proteus gets found

But this time xmlrpclib is missing

Also, xmlrpclib is not declared as a dependency in the Proteus setup.py file

I think I' ll take Fredy's suggestion, I'll build Proteus on my own and try to use that

Only, not right now.
Tomorrow
Thanks for your suggestions
Good night

xmlrpclib is a standard library of Python so it should not be declared
as dependency.
But indeed xmlrpclib is the name for Python2, in Python3 it should be
xmlrpc.
Normally, when installing proteus with Python3, the code is transformed
and xmlrpclib is changed for xmlrpc. So it seems the installation is
wrong. I guess it should be reported to the distribution you are using.

Wrong guess.

JFTR: It was explained on the Debian mailing list to Cato Nano that he has to
take care himself for 2to3 conversion when not using distribution packages and
running instead from a downloaded package.

I think Mathis is referring to my own Tryton module

He saw the path to my module in the stacktrace

Now I' m not sure I understand

Can't the Debian provided Proteus be used for developing your own Tryton modules?

Does it only work with Debian provided modules ?

As far as your module is importable from the debian python interpreter
it will work without problems.

How do you installed your module?

Sergi

thank you so much for your concern

I changed solution

I installed all with viertualenv and pip

For the server pip3, python3 and for the client pip2, python2 and a virtualenv that can access the pygtk provided by the local operating system (pygtk doesn' t install plainly so the one provided by the system is preferable)

I opened a python console and imported proteus a second ago and it works like a charm

I had stuck to the apt provided packages because I had assumed that they were reliable

I was wrong (to say at least)

Starting tomorrow I' ll try to debug my calculated field

Ugh !

Thank you so much to all of you for your help
Starting tomorrow I' ll try

You seem to have already imported trytond before running the
'set_trytond' so the previous import setup PostgreSQL as database
backend which does not have ':memory:' database.
Tryton can not change the backend during the run time, so it must be
set once at the beginning and not change during the execution.

No this is correct. So maybe you have TRYTOND_CONFIG environment

backend.

Today the error message is different. Yesterday I probably messed up because I was tired, it happens
So here I am now

For memory database, you can use create_db from
trytond.tests.test_tryton like it is done for the test.
Indeed the README is not useful: https://bugs.tryton.org/issue7056

I copied the test_tryton file in my project root, erased some stuff and left the create_db function
I get this
~/tributi/bridgehead2.py in create_db(name, lang)

ok I managed to get Proteus working

I figured out the passages of configuring and creating the database finally

Proteus is helping me less than I thought, though

Probably because I' d need more data to test properly

I' ll open a new thread

When called from within a python3 prompt, Proteus gets found
But this time xmlrpclib is missing
Also, xmlrpclib is not declared as a dependency in the Proteus setup.py file

xmlrpclib is a standard library of Python so it should not be declared
as dependency.
But indeed xmlrpclib is the name for Python2, in Python3 it should be
xmlrpc.
Normally, when installing proteus with Python3, the code is transformed
and xmlrpclib is changed for xmlrpc. So it seems the installation is
wrong. I guess it should be reported to the distribution you are using.

Wrong guess.
JFTR: It was explained on the Debian mailing list to Cato Nano that he has to
take care himself for 2to3 conversion when not using distribution packages and
running instead from a downloaded package.

I do not see where it is a wrong guess. In previous email, Cato Nano
said: "Of course Proteus is installed with apt-get".

There was a local Proteus interfering with the Debian one

Sorry

Another good example why you should never mess up an installation from
distribution with an installation from source.

Right

I had downloaded Proteus because I was _consideing_ to try to build and install it myself
But I never embarked in such a process. I never began

I just decomprrressed the tar.gz file there

I didn't expect that to interfere with the Debian supplied Proteus.

Rather, I'd say, because I was torred I overlooked the error message that was explicitly pointing to that decompressed folder, instead of a system provided one

So I bothered Mathias

Oh well :-/
