AttributeError: 'MonetTypeCompiler' object has no attribute 'visit_JSON'

[MitchellWeg]

We currently don't have support for the JSON column type.

class Job(Base):
    __tablename__ = 'job'
    job_id = Column(Integer, primary_key=True)
    key = Column(String)
    value = Column(JSON)

produces the following error:

AttributeError: 'MonetTypeCompiler' object has no attribute 'visit_JSON
