uuid-type

Provides a UUID data type to Saltcorn, which may be used as a primary key or as any other field.

To use the UUID type as a primary key for a table:

• Install this plug-in from the store.
• create the table as usual
• edit the ID field befor adding any rows, switching to type to UUID

Note that to use this plug-in, you will have to have the uuid-ossp extension installed in PostgreSQL. This cannot be done from inside Saltcorn as it requires administrative access to your database. As postgres user, you should run this command on the database saltcorn uses:

create extension if not exists "uuid-ossp";

For instance, if your database is called saltcorn and you are logged in as root, you can run the following shell command:

sudo -iu postgres psql -U postgres -d saltcorn -c 'create extension if not exists "uuid-ossp";'

Note that if you reset your schema using saltcorn reset-schema, you may have to run this command again.

On recent DigitalOcean marketplace droplets (initial version >=0.4.4) the uuid-ossp extension has already been installed. If you have a droplet created prior to that, upgrading Saltcorn will not issue this command on its own. You will need to issue the command to create the extension on the terminal.
