Specify Calendar to Sync

Specify Which Google Calendar Syncs with Odoo

Let each user choose exactly which Google Calendar to synchronize — no more being stuck with just the primary one.

✓ Odoo 19 Compatible

By default, Odoo syncs only your primary Google Calendar. Specify Calendar to Sync empowers users who manage multiple calendars — Work, Team, Projects, Shared — to pick the exact one for synchronization with Odoo events.

⚡ Key Features

📅

Per-User Calendar Selection

Each user independently selects which Google Calendar syncs with their Odoo events. No global setting — full individual control.

🔌

One-Click Calendar Fetch

Click “Fetch My Google Calendars” to instantly load all your available calendars from Google.

🔄

Smart Calendar Switching

Switch calendars anytime with configurable policies — choose what happens to existing events and how the next sync behaves.

🔒

Seamless OAuth2 Integration

Works with Odoo’s existing Google OAuth2 setup. No extra credentials or API keys required.

🌞

Calendar Color Inheritance

Odoo event colors automatically mirror your Google Calendar color. Enable the toggle once and keep your color scheme consistent across both platforms.

📋

Per-Event Calendar Override

Route individual events to a specific Google Calendar directly from the event form — overriding the user’s default calendar when needed.

🛡

ACL Roles Awareness

Displays your Google Calendar access role (owner, writer, reader). Shows a warning banner when you try to sync with a calendar you can’t write to.

💡 How It Works

1

Connect your Google account in Odoo (as usual).

2

Click “Fetch My Google Calendars” in your user preferences.

3

Select the calendar you want (Work, Project, Team, etc.).

4

All future syncs use your chosen calendar instead of “primary”.

🎯 Ideal For

💼 Multi-Calendar Professionals

Users juggling personal, work, and project calendars.

🏢 Organizations

Companies using shared Google Calendars across departments.

👥 Team Leads

Teams that want one calendar per department or resource synced with Odoo.

Specify Calendar to Sync — Google Calendar

by Grevlin Global Corp

Specify Calendar to Sync - Google Calendar

Overview

This module extends Odoo's Google Calendar integration to allow each user to select which of their Google Calendars should be synchronized with Odoo events.

By default, Odoo syncs only the user's primary Google Calendar. With this module installed, users who manage multiple calendars (Work, Team, Projects, Shared) can pick the exact one for synchronization with Odoo events.

Key Features

  1. Per-user Google Calendar selection
  2. One-click calendar fetch from Google
  3. Configurable event migration policies when switching calendars
  4. Calendar color inheritance from Google to Odoo
  5. Per-event calendar override from the event form
  6. ACL roles display with read-only calendar warning
  7. Seamless integration with Odoo's existing Google OAuth2 setup
  8. No additional API keys or credentials required

Configuration

Prerequisites

  1. Install and configure the standard Google Calendar module (:menuselection:`Apps --> Google Calendar`).
  2. Set up Google OAuth2 credentials in :menuselection:`Settings --> General Settings --> Integrations --> Google Calendar`.
  3. Install the Specify Calendar to Sync module.

Connecting Your Google Account

Each user must connect their Google account before selecting a calendar:

  1. Navigate to :menuselection:`Settings --> Users & Companies --> Users`.
  2. Open your user profile.
  3. Under the :guilabel:`Calendar` tab, click :guilabel:`Synchronize with Google`.
  4. Complete the Google OAuth2 authorization flow.

Usage

Fetching Your Calendars

Once your Google account is connected:

  1. Open your user profile (:menuselection:`Settings --> Users & Companies --> Users`) or your preferences (:menuselection:`Settings --> Preferences`).
  2. Click the :guilabel:`Fetch My Google Calendars` button.
  3. All calendars associated with your Google account are loaded, including their names, colors, and your access role.

Selecting a Calendar

After fetching calendars, a dialog appears:

  1. Choose the desired calendar from the :guilabel:`Calendar` dropdown.
  2. If you are switching from a previously selected calendar, configure the event migration policies:
    • :guilabel:`User's Existing Events`: Choose whether to leave events untouched, delete from Google, delete from Odoo, or delete from both.
    • :guilabel:`Next Synchronization`: Choose whether to synchronize only new events or all existing events.
  3. Click :guilabel:`Confirm` to save your selection.

All future synchronization operations will use your chosen calendar instead of the primary one.

Tip

You can change your selected calendar at any time by clicking :guilabel:`Fetch My Google Calendars` again and choosing a different calendar.

Warning

If you select a calendar where your access role is reader or freeBusyReader, a warning banner is displayed in the dialog. Odoo will not be able to create or update events in a read-only calendar.

Calendar Color Inheritance

Each Google Calendar has a background color set in Google. When color inheritance is enabled, Odoo event colors automatically mirror that Google Calendar color.

To enable color inheritance:

  1. Open your user profile or preferences.
  2. Under the :guilabel:`Calendar` tab, enable the :guilabel:`Inherit Google Calendar Color` toggle.

Once enabled, all events synchronized from your selected Google Calendar will display the matching color in Odoo's calendar view.

Per-Event Calendar Override

Individual events can be routed to a different Google Calendar without changing your default calendar selection.

To override the calendar for a specific event:

  1. Open the calendar event form.
  2. Locate the :guilabel:`Google Target Calendar` field (below the :guilabel:`Location` field).
  3. Select the desired Google Calendar from the dropdown.
  4. Save the event.

On the next synchronization, that event will be sent to the selected override calendar rather than your default one.

Note

The override calendar must be one of the calendars you have already fetched. Only calendars listed in your :guilabel:`My Google Calendars` are available for selection.

Technical Details

Models

google.calendar.identification
Stores the list of Google Calendars available to each user, including the calendar name, Google ID, background color, access_role (owner/writer/reader/freeBusyReader from the Google Calendar List API), and computed odoo_color (mapped from background_color via HSV analysis).
res.users (extended)
Adds current_google_calendar_id (the user's selected Google Calendar), user_google_calendar_ids (all fetched calendars), is_google_synced (computed), and google_calendar_inherit_color (color inheritance toggle).
google.calendar.sync (extended)
Adds google_calendar_id to tag synced events with the calendar they belong to.
calendar.event (extended)
Adds google_target_calendar_id for per-event calendar routing. The _odoo_values() method applies color and calendar tagging; _google_values() injects the _odoo_target_calendar routing hint consumed by the API layer.

API Extensions

The module extends GoogleCalendarService with calendar-aware operations. The get_events, insert, patch, and delete methods accept an optional calendar parameter (defaults to 'primary').

The routing hint _odoo_target_calendar travels in the _google_values() dict and is consumed (popped) by insert() before the payload is sent to Google.

Seems interesting! Is possible to customize the module allowing to sync the tasks of a project ? I would select a calendar to sync in the project settings and all the task will be in the specific google calendar selected.
