I’ve the mannequin that the pictures present. Within the entity Phrase I’ve the attribute identify, that I wish to be constraint. If I do not make it constraint the mannequin works completely, however after I make it constraint it crashes simply when opening giving this error. The one code it reads is a DataController wherein I simply create the container and set mergePolicy to NSmergeByPropertyObjectTrumpMergePolicy.
I believe I would like identify in Phrase to be constraint. In any other case when deleting or including relations with train_list or test_list I get many phrases with the identical identify, after I simply need one that’s added or deleted from these lists.
I do not actually know what are the necessities to make use of a constraint. Possibly there’s a battle with the relationships I’ve or the delete guidelines. Any thought?
