[zhangchunlin]

settings:

[MODELS]
gerritsyncsession = 'gitfetchdata.models.GerritSyncSession', 'external'

Traceback (most recent call last):
  File "/home/zhangclb/oss/uliweb/uliweb/core/dispatch.py", line 112, in call
    _f(sender, *args, **kw)
  File "/home/zhangclb/oss/uliweb/uliweb/contrib/orm/__init__.py", line 63, in after_init_apps
    raise Exception("Model path should be a string but %r found" % model_path)
TypeError: not all arguments converted during string formatting

So is there any problem with my settings?

Should use MODELS_CONFIG like this: https://github.com/limodou/uliweb/blob/master/test/test_multidb/apps/blog/settings.ini#L5
