I have problem in using tkinter plugin.
I am using ubuntu 12.10 desktop in my local system and i installed python 2.7 and 3.2
I used tkinter plugin in OpenERP it works fine in my local pc.
But the problem is when use same code in server (Ubuntu 12.04 Server) it doesn't works
self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk,sync, use)
TclError: no display name and no $DISPLAY environment variable
It would have been nice to include the full traceback and a larger code extract. The error message means that Tkinter is unable to find your X graphical environment, which likely means you're running the code on a headless server, as Dominic pointed out. You could try to install X on the server, but there's no need for a GUI if the machine is really meant to be a server with no user interface.
If you do need to display a GUI when that code is executed, then it should either not run on the server-side or you need to setup X11-forwarding to the client machine. This does not seem to make a lot of sense in an OpenERP context though - as it would hardly work in a generic manner for all users.
Now are you perhaps using matplotlib to produce graphics (your code extract does not show that)? If yes, you can simply force it to use a headless backend for producing the images, as explained in this question or this other question.
Try to have the following code executed before the rendering code is called:
import matplotlib import matplotlib.pyplot # force headless backend, or set 'backend' to 'Agg' # in your ~/.matplotlib/matplotlibrc matplotlib.use('Agg') # force non-interactive mode, or set 'interactive' to False # in your ~/.matplotlib/matplotlibrc matplotlib.pyplot.ioff()
