Item in ``from list'' not a string (custom_import.py) web2py 2.9.11

[Luciano Laporta Podazza]

Hello,

I'm using locally web2py (2.9.8) + Shopify API (2.0.4) on Mac OS X 10.9.5 (Python 2.7.5) and this code works perfectly:

from gluon.tools import Service
service = Service()
import gluon.contrib.simplejson as json


def call():
    session.forget()
    return service()


@service.json
def create_order():
    data = json.loads(request.body.read())
    import shopify
    #(API Key, Password)
    shop_url = "https://%s:%s...@myshop.myshopify.com/admin" % ('key','secret')
    shopify.ShopifyResource.set_site(shop_url)
    shop  = shopify.Shop.current
    orders = shopify.Order.find(financial_status='pending')
    new_order = shopify.Order()


    for order in orders:
        if order.order_number == data['order_number']:
            clone_order(order, new_order, order.attributes)


def clone_order(objfrom, objto, names):
    for n in names:
        if hasattr(objfrom, n):
            if n in ["source_name", "cart_token", "id", "token", "name", "checkout_token", "checkout_id"]:
                objto.n = None
            elif n == "line_items":
                v = getattr(objfrom, n)
                setattr(objto, n, v)
                if objto.line_items[-1].title != "Cargo por COD":
                    objto.line_items.append({"variant_id" : 972802884, "quantity" : 1, "price": 2.5, "title": "Cargo por COD"})
            elif n == "order_number":
                v = getattr(objfrom, n)
                objto.note = "Agregado COD, numero de orden vieja: #" + str(objfrom.order_number)
            else:
                v = getattr(objfrom, n)
                setattr(objto, n, v)
                objto.order_number = 1198
    try:
        objto.save()
        objfrom.cancel()
        objfrom.close()
        return "Success"
    except Exception, e:
        return "Fail"

But when deploying to server (Ubuntu 14.04 with Web2py 2.9.11 / Python 2.7.6 -note the different python and web2py version-) I get this error:

I also tested it with web2py 2.9.11 locally and it works fine too so I can't figure it out where the issue is.

Any help will be appreciated. Thanks.

It seems to.

I've tried using pyenv to switch to Python 2.7.5 (the one it works), declared it as global and verified that works running 'python', reinstalled web2py 2.9.11 on server but web2py it still uses Python 2.7.6.

On the other hand I've tried to apply the patch with no luck (actually I'm learning how to do it :P)

Any suggestions?. Thanks!

it's not a web2py issue but it seems something with the Shopify lib and that bug that isn't going very well.... as of "web2py starts with something else" you need to check your setup.... web2py can't choose what python version to run at runtime....

[Luciano Laporta Podazza]

Thanks Niphlod,

I've just managed to make any python version work (< 2.7.5), web2py runs the Python version I want but the error still remains.

It's weird 'cause on my Mac, with Python 2.7.5 (default, Mar  9 2014, 22:15:05) it works like a charm.

I'll keep the research but this is driving me nuts.

Hi again,

So a friend of mine helped me solving the issue, on gluon/custom_import.py, on line 82 we have to replace this line:

modules_prefix, globals, locals, [itemname], level)

With this one:

modules_prefix, globals, locals, [itemname.encode('utf-8')], level)

And that's all!. 

Thanks for your support!
