Tryton as you might know already is an OpenSource ERP, a form of OpenERP. Tryton is a three-tiers high-level general purpose application platform under the license GPL-3 written in Python and using PostgreSQL as database engine. It is the core base of a complete business solution providing modularity, scalability and security.


Tryton Core

The core of Tryton (also called Tryton kernel) provides all the necessary functionalities for a complete application framework: data persistence, extensive modularity, users management (authentication, fine grained control for data access, handling of concurrent access of resources), workflow and report engines, web services and internationalisation. Thus constituting a complete application platform which can be used for any relevant purpose.


Note: to avoid installation download our virtual-environment with ready setup, just need postgresql and dbuser, trytondb,


Base Modules

Currently, the main modules available for Tryton cover the following fields of activity:

  • Accounting
  • Invoicing
  • Sale Management
  • Purchase Management
  • Analytic Accounting
  • Inventory Management

They establish a base and an easy to use abstraction of some of the key concepts for every business customization. Since a few months, I have been observing a good participation on Tryton google group, which is a good sign for Tryton. Let us introduce a basics : Database Creation, Module Installation, Company Configuration and Google maps! We will add the post for Tryton Installation very soon.

How to create new database user for postgresql ?

createuser –interactive –pwprompt
# We created tryton as user with password sb@123

# As below example to create new database.
# We don’t found tryton gives wizard to create new database.

Build Configuration File

create tryton.conf, for trytond server.

uri = postgresql://tryton:sb@123@localhost/




format=%(asctime)s] %(levelname)s:%(name)s:%(message)s
datefmt=%a %b %d %H:%M:%S %Y

args=('/tmp/tryton.log', 'D', 1, 30)

A database can be initialized using this command line:

#Syntax: trytond-admin -c <config file> -d <database name> –all
trytond-admin -c trytond1.conf –dev -d trytondb –all 

At the end of the process, trytond-admin will ask to set the password for the admin user.

Update a database

To upgrade to a new series, the command line is:

trytond-admin -c <config file> -d <database name> –all # avoidable step, not required until issue
