LOAD DATA LOCAL INFILE sqlalchemy and python to mysql db

Question

I'm trying to use LOAD LOCAL DATA INFILE with sqlalchemy to upload batch files to my server. I have edited my /etc/mysql/my.conf to contain local-infile == 1 under both [mysql] and [mysqld], yet I'm getting this traceback when I run the program.

The relevant line of code is:

    Traceback (most recent call last):
  File "main.py", line 48, in <module>
    con.execute(sql)
  File "/Users/eoddata/venv/lib/python2.7/site-packages/sqlalchemy/engine/base.py", line 906, in execute
    return self._execute_text(object, multiparams, params)

FIELDS TERMINATED BY ',' (Symbol,@Date,Open,High,Low,Close,Volume)\n                    
SET Date = STR_TO_DATE(@Date,'%%Y%%m%%d');"]

I've done some research from the docs and can't find a way to fix this error. With python MySQLdb (from pip install MySQL-Python) will allow me to pass in a local-infile paramter. I can't find an equivalent in SQLAlchemy. Any help is appreciated.

EDIT: I've worked on this all night and still haven't made any progress - a lot of dead ends. Any ideas?

Thanks, Jared

You should add local_infile=1 to the connection string.

SQLALCHEMY_DATABASE_URI = "mysql://user:pass@localhost/dbname?charset=utf8&local_infile=1"
