there is some namespacing needed
nah, "Foo" relates to the related object, not the relationship
I've got the additional fields created, but the data isn't loading
I've found this https://docs.silverstripe.org/en/4/developer_guides/forms/field_types/gridfield/#many-many-extrafields but it doesn't seem to work (the form is loaded, but the additional fields of the relationship object aren't populated)
are there any guides on managing many_many_through relationships in ModelAdmin? How do I expose/edit the additional data?
I've got a check for
validate() and it's triggering every time even when it's not changed
is it expected that saving an item with modeladmin marks things as changed when they're still set the same?
is there an established pattern for providing a file (eg a CSV) to a dev task?
how do I programmatically manage many_many_through relationships?
