Question

从1.7升级到1.8后，我面临着一个Django ValidationError。我搜索了这个错误，但没有运气。

在https://github.com/django/django/blob/master/django%2Fdb%2Fmodels%2Ffields%2F__init__.py#L958

引发错误

任何帮助都非常感激。

Django Version: 1.8.3
    Exception Type: ValidationError
    Exception Value:    
    [u"'xyz' value must be an integer."]
