Hi,
I experienced the exception while accessing a mysql database in
windows via sqlalchemy0.7.0.
It should be due to source code error in 0.7.0:
The member tables of class MetaData is created as immutabledict,
sqlalchemy\schema.py::line 2181
self.tables = util.immutabledict()
But the follow code try to change it's content:
sqlalchemy\dialects\mysql\base.py::line 1986
table.metadata.tables[lc_alias] = table
Could any people assist to resolve this issue?
Thanks,
log:
mysql://root:[email protected]/linelocationdb?charset=utf8&use_unicode=0
