Non admins can not delete autosaved document

[Paula-Kli]

When not saving a new document and creating a new one, one gets a hint to maybe reload the unsaved document. Being not a admin it is not possible to delete it afterwards

When you create a document and do not save it, you get the same behavior. It seems that only on save the author gets the required permissions.

It seems that at creation, the author is not saved into the database (information pages table). This makes it hard to check who the author is on deletion to allow the deletion to proceed.

It seems the user id is only saved in revisions, and on creation there is no revision yet, thus no user is saved. Naively this could be handled in two ways:

• Add an original author to documents. This would require a migration
• Allow deletion of documents without revisions to everyone (do not check permissions)
• Save the document and then delete it
