Delete a user

[marien-probesys]

Problem

Users may leave their structure and their corresponding data should either be deleted or anonymized.

Solution

Allow administrators to delete a user account. This solution deletes all the data related to the user (e.g. tickets, messages, entity events, etc.) Thus, the administrator must be warned about the risks.

Specifications

Form

Add a form at the bottom of the user edit page, allowing to delete the user.

There must be a warning to indicate that all the information, including tickets, messages and traceability related to this user will be deleted.

Clicking on the submit button must ask for confirmation.

Associations constraints

There are good chances that a lot of Entity associations will prevent the deletion because of the foreign keys' constraints.

Deletions must be applied in cascade at the database level, e.g.:

#[ORM\JoinColumn(nullable: false, onDelete: "CASCADE")]
private ?User $createdBy = null;

Some other user associations doesn't require the association to be set, so we can set the value to null:

#[ORM\JoinColumn(onDelete: "SET NULL")]
private ?User $assignee = null;

You can find all the relations with git grep 'private ?User'
