  • Extending the Tryton client ( e.g. to support a new widget ) is difficult. As very few Tryton developers provided upgrades to the client in the last few years, and as the status of the client code and documentation is not perfect and especially not easy to understand and to handle, it can be expected that writing a new widget for the client might just be done by a handful of Trycon developers in the world...

• I experienced: A Tryton 3.4 client may just communicate with a Trytond 3.4 server, communications with a Trytond 3.5 server is refused .
• Trytond uses the database, but the view and the models are defined in the file system. Each “object view” is a Trython object. A Tryton client is used to display a view. Trytond is parsing the XML files and stores the infos in its database.
• “Trytond - u mymodule anothermodule athirdmodule - d mydatabase”, “Trytond - u all - d mydatabase”
  • checks the module directory/directories for Python .py files, checks all XML files for changes and updates the database with the changes in XML files. Trytond parses all .py Python files to detect if there are new fields ( = global class variables ) in the .py Python files.
