To check if a user can perform an action, such as

edit

, you should use Ory Keto's [check-API](https://www.ory.sh/docs/keto/concepts/api-overview#check-relation-tuple) to determine whether the user (subject) has a specific relation on an object. In your case, you want to check if the user can

edit

the file

myfile

from the

File

namespace. Based on the information provided in the extracts, you should check for a specific permission like

edit

instead of a relationship like

editors

. The permission model will define which relationships are checked in the process. For example, if you have these permissions defined in your permission model: -

view

a document if the user is a

viewer

,

editor

, or

owner

of the document; or if the user can

view

the parent folder -

edit

a document if the user is a

editor

, or

owner

of the document; or if the user can

edit

the parent folder You can use the check-API to check if the user has the

edit

permission on the file

myfile

. The permission check will look up the relationships (like

editor

or

owner

) defined in the permission model. Unfortunately, the extracts do not provide a specific code example for this scenario. However, you can refer to the [Ory Keto documentation](https://www.ory.sh/docs/keto) for more information on how to use the check-API and set up your permission model.
