AttributeError: 'str' object has no attribute '_meta' (when using South)

Question

I'm getting this error when I use 'startmigration' in South.

My guess is that I have data that is not serializable.

What is the best way for me to determine the offending model?

Answer 1

Since something is asking for _meta attribute, then it means, that it expects model (or form, to be preceise, but I believe it's not the case) object, since models have _meta attributes, but you are passing a string. If you more help, you need to present some code, to determine what is wrong.

Answer 2

Try updating to the latest version of South. There have been some recent fixes for one cause of this.
