Yeah, the issue is that you are not returning anything. If you just do a return record it should not throw an error.

I'm getting an error when iterating over the records read from a very simple xlsx file. I've tried reading a csv file and the results are the same. The code below prints the 3 records in the file then it seems like it's attempting to read another record from the records collection. What am I doing wrong?
Thanks!
Here's the code:import os

from models import Product, ProductType, Event, CarClass, Vehicle, Registrant
from flask import render_template
from flask.ext.appbuilder.views import ModelView, BaseView, has_access, expose
from flask.ext.appbuilder.charts.views import ChartView
from flask.ext.appbuilder.models.sqla.interface import SQLAInterface
from flask.ext.appbuilder.widgets import ListBlock, ShowBlockWidget
import pyexcel as pe
from werkzeug import secure_filenamefrom app import dbdef doEventsImport():
    if request.method == 'POST':
        file = request.files['file']
        if file and allowed_file(file.filename):
            filename = secure_filename(file.filename)
            fullName = os.path.join(app.config['UPLOAD_FOLDER'], filename)
            file.save(fullName)

            records = pe.get_records(file_name=fullName)
            for record in records:
                print record
Console ouput of the 3 records:{'EventKey': u'TXABCD2014', 'Name': u'Texas All British Car Days 2014-a'}{'EventKey': u'TXABCD2015', 'Name': u'Texas All British Car Days 2015'}{'EventKey': u'TXABCD2016', 'Name': u'Texas All British Car Days 2016'}
