Hi, As a quick workaround, I thought of modifying serializers.custom_json in the following manner: 1. check whether the item is a lambda expression 2. if so, return its string representation (using repr())
I used a nice "islambda" function I found in http://bytes.com/topic/python/answers/39908-what-lambda-used-real-code I guess there's no point in returning the string represntation of the function to the user, so this probably won't be the final solution to this issue. What do yo think about this fix?
