How to configure Collections as Globals for multi-tenant

When using multi-tenant, globals need to actually be configured as collections so the content can be specific per tenant. To do that, you can mark a collection with isGlobal and it will behave like a global and users will not see the list view.

multiTenantPlugin({
  collections: {
    navigation: {
      isGlobal: true,
    },
  },
})

Customizing access control

In some cases, the access control supplied out of the box may be too strict. For example, if you need some documents to be shared between tenants, you will need to opt out of the supplied access control functionality.

By default this plugin merges your access control result with a constraint based on tenants the user has access to within an AND condition. That would not work for the above scenario.

In the multi-tenant plugin config you can set useTenantAccess to false:

// File: payload.config.ts

import { buildConfig } from 'payload'
import { multiTenantPlugin } from '@payloadcms/plugin-multi-tenant'
import { getTenantAccess } from '@payloadcms/plugin-multi-tenant/utilities'
import { Config as ConfigTypes } from './payload-types'

// Add the plugin to your payload config
export default buildConfig({
  plugins: [
    multiTenantPlugin<ConfigTypes>({
      collections: {
        media: {
          useTenantAccess: false,
        },
      },
    }),
  ],
  collections: [
    {
      slug: 'media',
      fields: [
        {
          name: 'isShared',
          type: 'checkbox',
          defaultValue: false,
          // you likely want to set access control on fields like this
          // to prevent just any user from modifying it
        },
      ],
      access: {
        read: ({ req, doc }) => {
          if (!req.user) return false

          const whereConstraint = {
            or: [
              {
                isShared: {
                  equals: true,
                },
              },
            ],
          }

          const tenantAccessResult = getTenantAccess({ user: req.user })

          if (tenantAccessResult) {
            whereConstraint.or.push(tenantAccessResult)
          }

          return whereConstraint
        },
      },
    },
  ],
})

Placing the tenants array field

In your users collection you may want to place the field in a tab or in the sidebar, or customize some of the properties on it.

You can use the tenantsArrayField.includeDefaultField: false setting in the plugin config. You will then need to manually add a tenants array field in your users collection.

This field cannot be nested inside a named field, ie a group, named-tab or array. It can be nested inside a row, unnamed-tab, collapsible.

To make it easier, this plugin exports the field for you to import and merge in your own properties.

import type { CollectionConfig } from 'payload'
import { tenantsArrayField } from '@payloadcms/plugin-multi-tenant/fields'

const customTenantsArrayField = tenantsArrayField({
  arrayFieldAccess: {}, // access control for the array field
  tenantFieldAccess: {}, // access control for the tenants field on the array row
  rowFields: [], // additional row fields
})

export const UsersCollection: CollectionConfig = {
  slug: 'users',
  fields: [
    {
      ...customTenantsArrayField,
      label: 'Associated Tenants',
    },
  ],
}
