Description

A wrong query is issued to the database, having empty table name and empty column names.

UPDATE "" SET "SortOrder" = 1 WHERE "" = 15 AND "" = 3

If, after hitting the error, you examine the database, you'll find the many-to-many table has the new record correctly appended, but the SortOrder column is set at 0. Manually changing it to 1 solves the problem. But anytime you need to create a new one, the problem is back.

Steps to Reproduce

Given the following relations, whenever you try to create a new Button, disregarding whether you do it from the View gridfield, or from the MetricGroup gridfield, you get a 500 and the above error.

@leonixyz One issue in the View class is that either you need to name the gridfield Buttons or call setCustomRelationName on GridFieldSortableRows to tell it what the name of the relationship is so it can find the correct relationship. In the View class the GridField's name is AttachmentsCategories for the buttons relationship. It looks like this is the case for all of the buttons at least. Double check your GridField names (or call that setCustomRelationName) and let me know if that fixes your issue 😄.
