I'm trying to learn more about the .egg concept and overriding methods in Python. Here's the error message I'm receiving:
Traceback (most recent call last):
File "C:/local/work/scripts/plmr/plmr_db.py", line 42, in <module>
insp.reflecttable(reo_daily_table, column_list)
File "build\bdist.win32\egg\sqlalchemy\engine\reflection.py", line 370, in reflecttable
File "build\bdist.win32\egg\sqlalchemy\engine\reflection.py", line 223, in get_columns
File "build\bdist.win32\egg\sqlalchemy\engine\base.py", line 260, in get_columns
NotImplementedError
Here's the specific function from base.py:
def get_columns(self, connection, table_name, schema=None, **kw):
"""Return information about columns in `table_name`.
Given a :class:`.Connection`, a string
`table_name`, and an optional string `schema`, return column
information as a list of dictionaries with these keys:
name
the column's name
type
[sqlalchemy.types#TypeEngine]
nullable
boolean
default
the column's default value
autoincrement
boolean
sequence
a dictionary of the form
{'name' : str, 'start' :int, 'increment': int}
Additional column attributes may be present.
"""
raise NotImplementedError()
So my question is - do I override this function by writing a new method in my main module? Or am I missing a step somewhere along the way with my imports? Or am I just completely off track here?
Any and all help is appreciated :)
edit: adding my code
import sys
from sqlalchemy import create_engine, select, Table, MetaData
from sqlalchemy.engine import reflection
dbPath = 'connection_string'
engine = create_engine(dbPath, echo=True)
connection = engine.connect()
#reflect tables into memory
meta = MetaData()
reo_daily_table = Table('reo_daily',meta)
insp = reflection.Inspector.from_engine(engine)
column_list=[...]
insp.reflecttable(reo_daily_table, column_list)
connection.close()
