Permission overview

A new User does not have permissions for any part of the system, unless they are explicitly given access. To get access they need to inherit Roles, typically assigned to the User Group they belong to.

Each Role can contain one or more Policies. A Policy is a rule that gives access to a single function in a module. For example, a section/assign Policy allows the User to assign content to Sections.

When you add a Policy to a Role, you can also restrict it using one or more Limitations. A Policy with a Limitation will only apply when the condition in the Limitation is fulfilled. For example, a content/publish Policy with a ContentType Limitation on the "Blog Post" Content Type will allow the User to publish only Blog Posts, and not other Content.

A Limitation, like a Policy, specifies what a User can do, not what they can't do. A Section Limitation, for example, gives the User access to the selected Section, not prohibits it.

See Available Limitations for further information.

Combining Policies

Policies on one Role are connected with the and relation, not or, so when Policy has more than one Limitation, all of them have to apply.

If you want to combine more than one Limitation with the or relation, not and, you can split your Policy in two, each with one of these Limitations.

Assigning Roles to Users

Every User or User Group can have many roles. A User can also belong to many groups, for example, Administrators, Editors, Subscribers.

It is best practice to avoid assigning Roles to users directly. Instead, try to organize your content so that it can be covered with general roles assigned to User Groups.

Using Groups is easier to manage and more secure. It also improves system performance. The more Role assignments and complex Policies you add for a given User, the more complex the search/load queries will be, because they always take permissions into account.

Use Cases

Here are a few examples of sets of Policies you can use to get some common permission configurations.

Enter back end interface

To allow the User to enter the back end interface (PlatformUI) and view all Content, you need to set the following Policies:

  • user/login
  • content/read

To let the User navigate through StudioUI, you also need to add:

  • content/versionread

These Policies will be necessary for all other cases below that require access to the PlatformUI.

Create and publish content

To create and publish content, the User must have (besides user/login and content/read) the following Policies:

  • content/create
  • content/edit
  • content/publish
  • content/versionread

This also lets the User copy and move content, as well as add new Locations to a Content item (but not remove them!).

Create content without publishing

This option can be used together with eZ Enterprise's content review options. Using the following Policies, the User is able to create content, but can't publish it; instead, they must send it for review to another User with proper permissions (for example, senior editor, proofreader, etc.).

  • content/create
  • content/edit

Note that without eZ Enterprise this setup should not be used, as it will not allow the User to continue working with their content.

Restrict editing to part of the tree

If you want to let the User create or edit Content, but only in one part of the content tree, you need to use Limitations. Three Limitations that could be used here are Section Limitation, Node Limitation and Subtree Limitation.

Let's assume you have two Folders under your Home: Blog and Articles. You can let a User create Content for the blogs, but not in Articles by adding a Subtree Limitation on the Blog Content item. This will allow the User to publish content anywhere under this Location in the structure.

A Section Limitation can be used similarly, but a Section does not have to belong to the same subtree in the content structure, any Locations can be assigned to it.

If you add a Node Limitation and point to the same Location, the User will be able to publish content directly under the selected Location, but not anywhere deeper in its subtree.

Multi-file upload

Creating content through multi-file upload is treated in the same way as regular creation. To enable upload, you need you set the following permissions:

  • content/create
  • content/read
  • content/publish

You can control what Content items can be uploaded and where using Limitations on the content/create and content/publish Policies.

A Node Limitation limits uploading to a specific Location in the tree. A Class Limitation controls the Content Types that are allowed. For example, you can set the Node Limitation on a "Pictures" Folder, and add a Class Limitation which only allows Content items of type "Image". This ensures that only files of type "image" can be uploaded, and only to the "Pictures" Folder.

Manage Locations

To add a new Location to a Content item, the Policies required for publishing content are enough. To allow the User to remove a Location, you need to grant them the following Policies:

  • content/remove
  • content/manage_locations

Hiding and revealing Location requires one more Policy: content/hide.

Removing content

To send content to trash, the User needs to have the same two Policies that are required for removing Locations:

  • content/remove
  • content/manage_locations

To remove an archived version of content, the User must have the content/versionremove Policy.

Further manipulation of trash requires the content/restore Policy to restore items from trash, and content/cleantrash to completely delete all content from the trash.

Registering Users

To allow anonymous users to register through the /register route, you need to grant the user/register Policy to the Anonymous User Group.

Permissions for custom controllers

You can control access to a custom controller by implementing the performAccessCheck() method.

In the following example the user does not have access to the controller unless they have the section/view Policy:

use eZ\Publish\Core\MVC\Symfony\Security\Authorization\Attribute;

public function performAccessCheck(): void
    $this->denyAccessUnlessGranted(new Attribute('section', 'view'));

Attribute accepts three arguments:

  • module is the Policy module (e.g. content)
  • function is the function inside the module (e.g. read)
  • limitations are optional limitations to check against. Here you can provide two keys:
    • valueObject is the object you want to check for, for example ContentInfo.
    • targets are a table of value objects that are the target of the operation. For example, to check if Content can be assigned to a Section, provide the Section as targets. targets accept Location, Object State and Section objects.

Checking user access

To check if a user has access to an operation, use the isGranted() method. For example, to check if Content can be assigned to a section:

$hasAccess = $this->isGranted(
    new Attribute( 'section', 'assign', array( 'valueObject' => $contentInfo, 'targets' => $section ) )

You can also use the permission resolver (eZ\Publish\API\Repository\PermissionResolver). The canUser() method checks if the user can perform a given action with the selected object.

For example: canUser('content', 'edit', $content, $location ); checks the content/edit permission for the provided Content item at the provided Location.

Blocking access to controller action

To block access to a specific action of the controller, add the following to the action's definition:

$this->denyAccessUnlessGranted(new Attribute('state', 'administrate'));
