bson.errors.InvalidDocument: Cannot encode object: True

Question

I got an error when inserting a document in Mongo using python.

    document = {u'Status': 'Active',
     u'Installation': {u'IsFrugal': True,  u'IsFeatureSet': True,  u'IsEvolving': True, u'IsAffordable': True}, 
      u'AutoList': [u'IsFeatureSet', u'IsAffordable', u'IsFrugal'] 
    }

TraceBack Error is

    C:\Python27\lib\site-packages\pymongo-2.5.1_-py2.7-win32.egg\pymongo\collection.

    "bson.errors.InvalidDocument: Cannot encode object: True"

When I using the "true" instance of True it works well, but it will insert a string value I want to add Boolean value, not a string.

When I trying to insert simple {"name": True}, it works well. How it is possible? What's going wrong?

Answer 1

Going by the stack trace, tempdict is likely the value True rather than a dictionary of data to be inserted due to a problem elsewhere in the application (such as the rrpython library).
