System to sale and manage odoo databases.

Requirements

To start SaaS system you need:

Build and run

Execute saas.py script and wait some time

python saas.py –portal-create –server-create –plan-create –run –odoo-script=/path/to/openerp-server –odoo-config=/path/to/openerp-server.config

The SaaS system is ready! Try, for example, open start page:

Odoo (OpenERP) addons to provide SaaS

Structure of SaaS system:

  • SaaS Portal – main database
  • SaaS Servers – technical databases to control client databases. SaaS server create, edit, delete databases. Each SaaS Server can be installed on a separate machine (e.g. VPS)
  • SaaS Clients – client database to be used by customers. Each SaaS Client is attached to a SaaS Server.

Features

  • create SaaS Client databases:
    • manually from SaaS Portal backend
    • by client after choosing subdomain (similar to https://www.odoo.com/page/start ) – module saas_portal_start
    • by client after choosing database template (e.g. template for POS, template for ECommerce etc) with auto-generated subdomain (e.g. demo-12345.odoo.com) – module saas_server_templates
    • by client after singing up – module saas_portal_signup
  • prepare templates for new SaaS Client database. You are able to connect to template database, install modules you need, edit configuration, edit access rights for customer etc. Such template database will be exactly what a customer will see after database creating.
  • connect to existed SaaS Client database as administrator
  • control SaaS Client database from SaaS Portal backend:
    • install, update, delete addons
    • configure parameters (e.g. Max Allowed Users)
  • collect information from client databases (count of users, disk space usage, etc.)
  • notify customers about news by sending messages to Whole Company messaging group (under development)
  • show message at the top of a page (e.g. Your free trial will expire in about 4 hours Register now to add 15 days for free!) (under development)

Usage

  1. Configure Odoo installation
    • set dbfilter in config file or run odoo with –db-filter parameter, e.g. ^%h$
      • be sure, that you don’t use db_name in config file and don’t run odoo with -d (–database) parameter
      • check odoo documentation for understanding db filter and database parameters.
    • execute commands below to allow create databases with dots in name:

    cd path/to/odoo

    sed -i ‘s/matches=”[^”]*”//g’ addons/web/static/src/xml/base.xml

    • If you run odoo locally, add domains you are going to use to /etc/hosts. E.g.

    127.0.0.1 odoo.local # portal

    127.0.0.1 s1.odoo.local # server

    127.0.0.1 t1.odoo.local # template

    127.0.0.1 t2.odoo.local # template

    127.0.0.1 client-x.odoo.local

    127.0.0.1 client-y.odoo.local

    127.0.0.1 client-z.odoo.local

    • Redirect requests to domains above to localhost:8069 (e.g. via nginx)
      • be sure, that odoo gets host header, e.g. for nginx:

      proxy_set_header Host $host;

      proxy_set_header X-Real-IP $remote_addr;

      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

      proxy_set_header X-Forwarded-Proto $scheme;

    • install dependencies:
      • oauthlib:
        • pip install oauthlib
      • requests
        • pip install requests –upgrade
  2. Create two databases (via /web/database/manager):
    • Main Database, e.g. odoo.local:
      • install saas_portal and saas_portal_* (optional) modules
    • Server Database, e.g. s1.odoo.local
      • install saas_server
  3. Configure Server Database
    • Tick “Technical Features” for admin at Settings/Users/Users – Administrator
      • Refresh page
    • Open Settings/Users/OAuth Providers – SaaS
      • click [Edit]
      • update domain name at “Authentication URL” and “Validation URL”, change http to https if needed. E.g.
        • http://odoo.local/oauth2/auth
      • http://odoo.local/oauth2/tokeninfo
      • Edit Body according to your brand
      • click [Save]
      • remember value of Client ID field. It’s a database.uuid of SaaS Server.
  4. Configure Main Database:
    • open Settings/Configuration/SaaS Portal Settings
      • set Base SaaS domain, e.g. odoo.local
      • click Apply (do it even if you didn’t make changes)
  5. Register Server Database in Main Database
    • open SaaS/SaaS/Servers
      • click [Create]
      • set Database Name, e.g. s1.odoo.local
      • fix autogenerated Database UUID to actual one (see previous section)
      • click [Save]
  6. Create Plan
    • open Saas/SaaS/Plans
      • click [Create]
      • set Plan’s name, e.g. “POS + ECommerce”
      • set SaaS Server
      • set Template DB: type name, e.g. t1.odoo.local, and click Create “t1.odoo.local“
      • click [Save]
      • click [Create Template DB].
      • wait couple minutes while Database is being created.
      • click [Sync server]
  7. Prepare Template Database for Plan
    • click [Log in to template DB] at Plan’s form
      • be sure that you allow pop-ups in your browser
    • install modules that will be used for Plan, e.g. point_of_sale, website_sale
    • make any other changes in database if needed. E.g. configure chart of accounts.
    • open Settings/Users/Users – onwer_template. Configure Access Rights for Owner.
  8. Try to create database from template
    • open SaaS/Saas/Plans – select plan
      • click [Create Client]
      • set DB Name, e.g. client-x.odoo.local
      • click [Create]
      • wait couple minutes while Database is being created.
      • click [Sync server]
    • open SaaS/SaaS/Client – choose client
      • click [Configure]
        • open Parameters tab
      • add parameter “Max Users”, set Value 2
      • click [Execute]
      • click [Close]
      • click [Log in]
        • you see created database
      • try to create new user to test “Max Users” setting
  9. Get more
    • check description of other saas_* modules to get more features

Client database customization

The key question of client database customization is how to restrict administration rights. For example, client users should not be able to uninstall saas_client module, edit ir.confir_parameter records etc. The simplest solution is don’t give to customer access to administration. To make more flexible configuration, you could install following modules on SaaS Client databases:

(some modules are not ported for 8.0. Contribution is welcome)

  • ir_rule_protected – makes impossible for non-superuser admin edit\delete protected ir.rule
  • access_restricted – makes impossible for administrator set (and see) more access rights (groups) than he already have. (follow the link for more description)
  • hidden_admin – makes admin (user and partner) invisible
  • access_apps – allows to have administrators which don’t have access to Apps
  • access_settings_menu – allows to show settings menu for non-admin

API integration

To control SaaS via external tool built-in XML-RPC can be used.

Example in python language:

# Import libs
import json
import xmlrpclib
import requests

# Define credentials
main_url = 'http://odoo.local'
main_db = 'odoo.local'
admin_username = 'admin'
admin_password = 'admin'

# Authenticate
common = xmlrpclib.ServerProxy('{}/xmlrpc/2/common'.format(main_url))
admin_uid = common.authenticate(main_db, admin_username, admin_password, {})
models = xmlrpclib.ServerProxy('{}/xmlrpc/2/object'.format(main_url))

# Signup a user
# (would raise error, if user already exists)
client_username = '[email protected]'
client_name = 'Client Name'
client_password = 'Client Password'
models.execute_kw(main_db, admin_uid, admin_password, 'res.users', 'signup', [{
    'login': client_username,
    'name': client_name,
    'password': client_password,
}])

# Authenticate the user at Main Database
client_uid = common.authenticate(main_db, client_username, client_password, {})

# Get user session at Main Database if needed
params = {'db': main_db, 'login': client_username, 'password': client_password}
data = json.dumps({'jsonrpc': '2.0', 'method': 'call', 'params': params})
r = requests.post('%s/web/session/authenticate' % main_url,
                  data=data,
                  headers={'Content-Type':'application/json'})
if not r.json()['result']['uid']:
    raise Exception('Authenticaion failed')
client_session_id = r.json()['result']['session_id']


# Create new Client database
plan_id = 1  # specify plan you need
client_db = 'client.odoo.local'

# you can keep client_db empty to generate it automatically
# from "DB Names" parameter in Plan's form

client_db = False
res = models.execute_kw(main_db, admin_uid, admin_password,
                        'saas_portal.plan', 'create_new_database',
                        [plan_id], {'dbname': client_db, 'user_id':client_uid})

res['url']  # contains url for new database with client's access token.
saas_portal_client_id = res['id']

# Configure system
data = {
    'update_addons': [],
    'install_addons': ['sale', 'point_of_sale'],
    'uninstall_addons': [],

    'params': [
         {'key': 'saas_client.max_users', 'value': 10, 'hidden': True}
    ],
}
res = models.execute_kw(main_db, admin_uid, admin_password,
                        'saas.config', 'do_upgrade_database',
                        [data, saas_portal_client_id])

Notes abouts API integration

  • Be sure, that Portal module is installed at Main Database
  • Be sure, that “Allow external users to sign up” option from “Settings/General Settings” is enabled
  • To find new signuped user open “Settings/Users” at Main Database and delete filter “Regular users only”
  • don’t use trailing slash at main_url
  • Access token is expired in one hour
  • In case of log out, client has to click “Log in via SaaS Portal”. Client will be navigated to Portal database and can use client_username and client_password. After that the client will be returned back to his database. Important thing here, is that the client is not able to use client_password at login page of his database.
