currently when I DELETE an item which is being referenced by. I can still delete it. I would like to prohibit this giving an error. I couldn't find anything on http://docs.python-eve.org or google.
say I have the following two schemas:
foos =
...
'schema' :
...,
'bar':
'type': 'string',
'required': true,
'data_relation':
'resource': 'bars',
'field': 'name',
'embeddable': True
bars =
...
'schema' :
...,
'name':
'type': 'string',
'required': true,
if I delete now an item from bars which is still being referenced by >=1 items in foos. How could I return an error instead of deleting the bars item?
Would i need to write a
on_delete_item
def event(resource_name, item)
and how? Any help is appreciated.
