It doesn't say, that it connects to some other instance, but that it provides 'direct access to a trytond/tryton instance on the same machine'. http://codereview.appspot.com/2552041/diff/1/doc/topics/trytondasmodule.rst#n... doc/topics/trytondasmodule.rst:46: >>> CONFIG.load() On 2010/10/18 16:30:00, udono wrote: > After this I would overwrite the loaded config to database type sqlite and > :memory: for passing the doctest. Thanks, good idea. I will try if it is possible to set PYTHONPATH as required. Then it can make sense to run this doctest automatically at all. See also the codereview description.

It will be more consisting to have the same title than the file name. http://codereview.appspot.com/2552041/diff/6001/doc/topics/trytondasmodule.rs... doc/topics/trytondasmodule.rst:9: a trytond/tryton instance on the same machine providing the internal API to On 2010/10/25 21:38:01, yangoon wrote: > On 2010/10/25 14:09:42, ced wrote: > > It is not access to instance but to data > > For me it is access to data by means of an API. And trytondasmodule is access to > that API. Ok. But it is not accessing to an instance of trytond. So I propose this: Using trytond as a module allow to access to data by using the internal Python API. http://codereview.appspot.com/2552041/diff/6001/doc/topics/trytondasmodule.rs... doc/topics/trytondasmodule.rst:17: Interaction with a Tryton server (trytond) with a simple import On 2010/10/25 21:38:01, yangoon wrote: > On 2010/10/25 14:09:42, ced wrote: > > It is not to a server. > > ?? > If trytond is not a server why do you write > http://news.tryton.org/2010/09/some-news-from-development.html > ? I don't say that. I said that you don't interact with a server. You use the same code. http://codereview.appspot.com/2552041/diff/6001/doc/topics/trytondasmodule.rs... doc/topics/trytondasmodule.rst:22: can do something like export PYTHONPATH=/path/to/trytond/:$PYTHONPATH .

If you really want to describe the usage of database cursor in Python, just link to http://www.python.org/dev/peps/pep-0249/ http://codereview.appspot.com/2552041/diff/6001/doc/topics/trytondasmodule.rs... doc/topics/trytondasmodule.rst:31: * It is possible to do safe tests just by avoiding the cursor.commit() call.

I will omit it. Neither, you can run it with `python script.py` You will never see this in the Python documentation. http://codereview.appspot.com/2552041/diff/6001/doc/topics/trytondasmodule.rs... doc/topics/trytondasmodule.rst:43: ... sys.path.insert(0, os.path.dirname(DIR)) On 2010/10/25 21:38:01, yangoon wrote: > On 2010/10/25 14:09:42, ced wrote: > > I find this code is not clear for tutorial > > I can elaborate, that here the path to trytond is set by other means than > environment. As we said above that trytond must be in the PYTHONPATH, it is not required to have this code. And moreover it can confuse reader with unnecessary trick. http://codereview.appspot.com/2552041/diff/6001/doc/topics/trytondasmodule.rs... doc/topics/trytondasmodule.rst:55: >>> CONFIG['db_type'] = 'sqlite' Why changing configuration from trytond.conf ?

This doc is not a test. But someone could run it and get an error message which is odd. Why not create a category and add the party on it and then browse it to check if the category is there.
