django外键引用错误

我有两个文件中的两个模型导入另一个。其中一个通过外键连接到另一个。为了避免循环导入，我试图确定在引号外键：django外键引用错误

from pubscout.models import Campaign 
class RuleSuite(models.Model): 
    campaign = models.ForeignKey('Campaign', verbose_name="Кампания")

这对其他型号工作过，但这次我得到一个错误：

... 
    ... 
    File "/Users/1111/.virtualenvs/django_cpa/lib/python2.7/site-packages/django/contrib/admin/checks.py", line 719, in _check_list_filter_item 
    get_fields_from_path(model, field) 
    File "/Users/1111/.virtualenvs/django_cpa/lib/python2.7/site-packages/django/contrib/admin/utils.py", line 479, in get_fields_from_path 
    parent = get_model_from_relation(fields[-1]) 
    File "/Users/1111/.virtualenvs/django_cpa/lib/python2.7/site-packages/django/contrib/admin/utils.py", line 430, in get_model_from_relation 
    return field.get_path_info()[-1].to_opts.model 
    File "/Users/1111/.virtualenvs/django_cpa/lib/python2.7/site-packages/django/db/models/fields/related.py", line 661, in get_path_info 
    opts = self.remote_field.model._meta 
AttributeError: 'unicode' object has no attribute '_meta'

我应该在哪里看要解决这个问题？

这是一个古老的答案，http://stackoverflow.com/a/4379094/5781248 –

您需要限定型号名称与应用标签：

campaign = models.ForeignKey('appname.Campaign', verbose_name="Кампания")
