How to force a specific user in the Author textfield in Rules Create Entity I created a rule which creates an entity. I would like that every created entity has a specific author.

for the moment, it's look like I can only put the currently logged-in user in that textfield.
You will have to fetch a user entity first. There's an action called fetch entity by id, which will allow you to select user as type and specify the user id.



At the bottom you can assign label and machine name for the variable that will be made available.



make sure to do the fetching before creating the new entity, else this variable won't be available.
