Sometimes, when integrating remote data, entities of an entity-type are read-only, i.e. save() and delete() is not implemented. As this is a rather rare use-case, I don't think this warrants dealing with a separate interface or something. Still, I think it would be valuable to have an "official" flag so that at least entities can be marked accordingly and contribs could easily reflect that.

Then, we can document for save() and delete() to throw exceptions if they are invoked for a read-only entity.

Note, that contact message entity could qualify for that. While we cannot even load that, in having a load() is no harm. You can use it only with an ID anyway - as there exists no contact ID there is problem in that being called incorrectly - it can always just do nothing (= IDs are unknown).

However, calling save() on a contact message would create troubles. So having that flag + exception would be a good idea here.

I definitely think this warrants a separate interface. We could also make the storage controller optional and then check on the existance of one.

There is now a null implementation of the storage controller for contacts, so saving them will simply do nothing.

That's exactly what I was looking for. Is there some code examples or some more information for this purpose?

You kinda need this on your entity type:

 * @ContentEntityType(
 *   id = "contact_message",
 *   handlers = {
 *     "storage" = "Drupal\Core\Entity\ContentEntityNullStorage",
*    }
* )

Thank you for creating this issue to improve Drupal.

We are working to decide if this task is still relevant to a currently supported version of Drupal. There hasn't been any discussion here for over 8 years which suggests that this has either been implemented or is no longer relevant. Your thoughts on this will allow a decision to be made.

Since we need more information to move forward with this issue, the status is now Postponed (maintainer needs more info). If we don't receive additional information to help with the issue, it may be closed after three months.

Thanks!
