Collection Access Control

Collection Access Control is Access Control used to restrict access to Documents within a Collection, as well as what they can and cannot see within the Admin Panel as it relates to that Collection.

To add Access Control to a Collection, use the access property in your Collection Config:

import type { CollectionConfig } from @hanzo/cms'from 

export const CollectionWithAccessControl: CollectionConfig = {
  // ...
  access: {
    // highlight-line
    // ...
  },
}

Config Options

Access Control is specific to the operation of the request.

To add Access Control to a Collection, use the access property in your Collection Config:

import type { CollectionConfig } from @hanzo/cms'from ;

export const CollectionWithAccessControl: CollectionConfig = {
  // ...
  // highlight-start
  access: {
    create: () => {...},
    read: () => {...},
    update: () => {...},
    delete: () => {...},

    // Auth-enabled Collections only
    admin: () => {...},
    unlock: () => {...},

    // Version-enabled Collections only
    readVersions: () => {...},
  },
  // highlight-end
}

The following options are available:

Function	Allows/Denies Access
`create`	Used in the `create` operation. More details.
`read`	Used in the `find` and `findByID` operations. More details.
`update`	Used in the `update` operation. More details.
`delete`	Used in the `delete` operation. More details.

If a Collection supports Authentication, the following additional options are available:

Function	Allows/Denies Access
`admin`	Used to restrict access to the Admin Panel. More details.
`unlock`	Used to restrict which users can access the `unlock` operation. More details.

If a Collection supports Versions, the following additional options are available:

Function	Allows/Denies Access
`readVersions`	Used to control who can read versions, and who can't. Will automatically restrict the Admin UI version viewing access. More details.

Create

Returns a boolean which allows/denies access to the create request.

To add create Access Control to a Collection, use the create property in the Collection Config:

import type { CollectionConfig } from @hanzo/cms'from 

export const CollectionWithCreateAccess: CollectionConfig = {
  // ...
  access: {
    // highlight-start
    create: ({ req: { user }, data }) => {
      return Boolean(user)
    },
    // highlight-end
  },
}

The following arguments are provided to the create function:

Option	Description
`req`	The Request object containing the currently authenticated `user`.
`data`	The data passed to create the document with.

Read

Returns a boolean which allows/denies access to the read request.

To add read Access Control to a Collection, use the read property in the Collection Config:

import type { CollectionConfig } from @hanzo/cms'from 

export const CollectionWithReadAccess: CollectionConfig = {
  // ...
  access: {
    // highlight-start
    read: ({ req: { user } }) => {
      return Boolean(user)
    },
    // highlight-end
  },
}

Tip: Return a Query to limit the Documents to only those that match the constraint. This can be helpful to restrict users' access to specific Documents. More details.

As your application becomes more complex, you may want to define your function in a separate file and import them into your Collection Config:

import type { Access } from @hanzo/cms'from 
import type { Page } from '@/payload-types'

export const canReadPage: Access<Page> = ({ req: { user } }) => {
  // Allow authenticated users
  if (user) {
    return true
  }

  // By returning a Query, guest users can read public Documents
  // Note: this assumes you have a `isPublic` checkbox field on your Collection
  return {
    isPublic: {
      equals: true,
    },
  }
}

The following arguments are provided to the read function:

Option	Description
`req`	The Request object containing the currently authenticated `user`.
`id`	`id` of document requested, if within `findByID`.

Update

Returns a boolean which allows/denies access to the update request.

To add update Access Control to a Collection, use the update property in the Collection Config:

import type { CollectionConfig } from @hanzo/cms'from 

export const CollectionWithUpdateAccess: CollectionConfig = {
  // ...
  access: {
    // highlight-start
    update: ({ req: { user } }) => {
      return Boolean(user)
    },
    // highlight-end
  },
}

Tip: Return a Query to limit the Documents to only those that match the constraint. This can be helpful to restrict users' access to specific Documents. More details.

As your application becomes more complex, you may want to define your function in a separate file and import them into your Collection Config:

import type { Access } from @hanzo/cms'from 
import type { User } from '@/payload-types'

export const canUpdateUser: Access<User> = ({ req: { user }, id }) => {
  // Allow users with a role of 'admin'
  if (user.roles && user.roles.some((role) => role === 'admin')) {
    return true
  }

  // allow any other users to update only oneself
  return user.id === id
}

The following arguments are provided to the update function:

Option	Description
`req`	The Request object containing the currently authenticated `user`.
`id`	`id` of document requested to update.
`data`	The data passed to update the document with.

Tip: For Collections with Drafts enabled, you can use update access to control who can publish by returning a query constraint on the _status field.

Delete

Similarly to the Update function, returns a boolean or a query constraint to limit which documents can be deleted by which users.

To add delete Access Control to a Collection, use the delete property in the Collection Config:

import type { CollectionConfig } from @hanzo/cms'from 

export const CollectionWithDeleteAccess: CollectionConfig = {
  // ...
  access: {
    // highlight-start
    delete: ({ req: { user } }) => {
      return Boolean(user)
    },
    // highlight-end
  },
}

As your application becomes more complex, you may want to define your function in a separate file and import them into your Collection Config:

import type { Access } from @hanzo/cms'from 
import type { Customer } from '@/payload-types'

export const canDeleteCustomer: Access<Customer> = async ({ req, id }) => {
  if (!id) {
    // allow the admin UI to show controls to delete since it is indeterminate without the `id`
    return true
  }

  // Query another Collection using the `id`
  const result = await req.payload.find({
    collection: 'contracts',
    limit: 0,
    depth: 0,
    where: {
      customer: { equals: id },
    },
  })

  return result.totalDocs === 0
}

The following arguments are provided to the delete function:

Option	Description
`req`	The Request object with additional `user` property, which is the currently logged in user.
`id`	`id` of document requested to delete.
`data`	The data being set on the document. For Trash-enabled collections, check `data.deletedAt` to differentiate between soft delete and permanent delete operations.

Tip: For Collections with Trash enabled, you can use the data argument to allow users to soft delete (trash) documents while restricting permanent deletion. See Trash Access Control for examples.

Admin

If the Collection is used to access the Admin Panel, the Admin Access Control function determines whether or not the currently logged in user can access the admin UI.

To add Admin Access Control to a Collection, use the admin property in the Collection Config:

import type { CollectionConfig } from @hanzo/cms'from 

export const CollectionWithAdminAccess: CollectionConfig = {
  // ...
  access: {
    // highlight-start
    admin: ({ req: { user } }) => {
      return Boolean(user)
    },
    // highlight-end
  },
}

The following arguments are provided to the admin function:

Option	Description
`req`	The Request object containing the currently authenticated `user`.

Unlock

Determines which users can unlock other users who may be blocked from authenticating successfully due to failing too many login attempts.

To add Unlock Access Control to a Collection, use the unlock property in the Collection Config:

import type { CollectionConfig } from @hanzo/cms'from 

export const CollectionWithUnlockAccess: CollectionConfig = {
  // ...
  access: {
    // highlight-start
    unlock: ({ req: { user } }) => {
      return Boolean(user)
    },
    // highlight-end
  },
}

The following arguments are provided to the unlock function:

Option	Description
`req`	The Request object containing the currently authenticated `user`.

Read Versions

If the Collection has Versions enabled, the readVersions Access Control function determines whether or not the currently logged in user can access the version history of a Document.

To add Read Versions Access Control to a Collection, use the readVersions property in the Collection Config:

import type { CollectionConfig } from @hanzo/cms'from 

export const CollectionWithVersionsAccess: CollectionConfig = {
  // ...
  access: {
    // highlight-start
    readVersions: ({ req: { user } }) => {
      return Boolean(user)
    },
    // highlight-end
  },
}

Note: Returning a Query will apply the constraint to the versions collection, not the original Collection.

The following arguments are provided to the readVersions function:

Option	Description
`req`	The Request object containing the currently authenticated `user`.
