For Experts only! This is an Experimental Unreleased addon.

Gramps is not designed to be used by multiple users at the same time. While using a MongoDB server remotely allows multiple users to connect to a database, doing so simultaneously WILL cause database corruption and loss of data. If you chose to set up for multiple user access, please backup frequently, and set up a system of your own to make sure that only one person is using Gramps at one time. Gramps or the family tree MUST be closed before allowing another user to access the database.

The MongoDB addon provides MongoDB database support for Gramps 5.x or greater.

MongoDB is an open-source document-oriented NOSQL database.

Prerequisites

Gnome-important.png
Note

These instruction assume you are using Linux or development environment. As the Gramps AIO & MacOS installers do not come with the Prerequisites and can not be installed easily. see 10491

Install the following packages:

  • mongodb
  • python3-pymongo

Start and enable the database service.

Windows & MacOS

As the Gramps AIO & MacOS installers do not come with the Prerequisites and can not be installed easily. see 10491

Windows
If you really want to experiment with mongodb, (I regard this as extremely advanced activity), you will have to build up a development environment for Gramps under Windows and then add the mongodb prerequisites there. See Gramps_for_Windows_with_MSYS2
MacOS
The Mac bundle is aimed at normal users. Tinkerers can use MacPorts and have more-or-less the same environment as on Linux. Note that Homebrew just downloads the Gramps bundle dmg, so it won't help in this case. See: Mac OS X:Build from source:MacPorts

Creating a family tree

In the "Family Tree" tab of the Preferences, set the "Database backend" to MongoDB.

Enter the Host and Port if using anything other than the defaults.

In the Family Tree Manager, click New and enter a family tree name.

Click the Load Family Tree button.

Create or import some data.

Viewing a database using mongo

From the command line type:

$ mongo

At the prompt type:

> show dbs

You should see your family tree listed.

> use Family_Tree_1

> show collections

> db.person.find()

Now you should see some data.

Some query examples

> db.person.find({"gramps_id": "I0044"})

> db.person.find({"primary_name.surname_list.surname": "Garner"}).count()

> db.person.find({"primary_name.surname_list.surname": "Garner", "gender": 0}).count()

> db.event.find({"type.string": "Birth"})
