I'm getting an error msg I don't understand, "global name EMR_globals
is not defined", and could use some help.
I've separated the application I'm building into several modules. One
of the modules holds variables I need to pass from one module to
another and is called 'EMR_globals'. Several other modules hold
functions or user menus and then 'EMR_main' controls the initial user
interaction. I'm using MySQL to hold the data.
The initial connection to the database is done by 'EMR_main'.
Functions then define and close a cursor for various queries. The
connection variable, 'conn', is defined 'conn = "" ' in EMR_globals
and then used in EMR_main. Unfortunately when a module.function
attempts to use it I get the error msg.
Here is the source of the error, module 'name_lookup':
def name_find(namefrag):
cursor = EMR_globals.conn.cursor(MySQLdb.cursors.DictCursor)
cursor.execute("SELECT patient_ID, firstname, lastname FROM
demographics WHERE lastname LIKE '%s%%'" % (namefrag))
results = cursor.fetchall()
for index, row in enumerate(results):
print "%d %s %s %s" % (index, row["patient_ID"],
row["firstname"], row["lastname"])
indx = int(raw_input("Select the record you want: "))
results_list = list(results)
a = str(results_list[indx]['patient_ID'])
print 'You have chosen patient ID # ' + a
cursor.execute("SELECT * FROM demographics WHERE patient_ID = %s"
% (a,))
selected_pt = cursor.fetchall()
# if this query returns more than one record the following code will
fail I think
print menus.menu_demographics(selected_pt['firstname'],
selected_pt['lastname'],
selected_pt['address'],
selected_pt['city'],
selected_pt['state'],
selected_pt['zipcode'],
selected_pt['phonenumber'])
print menus.menu_pt_record
cursor.close()
Thanks for any help. Mike
