copy.deepcopy(field) (Django 1.8.2, Python 2.7.6, on line 31)

[alejandroMA]

So i was getting a weird bug, the template would say:

• "A server error occurred. Please contact the administrator."

And in the terminal (running the development server):

• A big stack of errors (you know normal python error).
• (i'll place the stack at the end of the issue).

Any way, problem appear when using the render_field tag:

• If use alone with no attr (attr="value"), everything works perfectly.
• But if you place any attr, it breaks.

Digging in i found the problem on widget_tweaks/templatetags/widget_tweaks.py (line 26, 31):

• i simply commented those lines and everything works perfectly once again :)

# if not PY26:
    # # See https://bugs.python.org/issue1515.
    # # It is OK to not do it in Python 2.6 because
    # # Django versions which require deepcopy here (1.7+)
    # # don't support Python 2.6 anyways.
    # field = copy.deepcopy(field) 

(doble comment :P)

So the comment says Django (1.7+), but i think there should be a second condition because it looks like in some newer version of Django, that statement stopped working.

My configuration:

• virtualenv
• Django 1.8.2
• Python 2.7.6
• Mac Os 10.10
• widget_tweaks 1.4

Thanks for reading! 👍

Ok, terminal stack trace:

Could you try it with django-widget-tweaks 1.4.1?

[alejandroMA]

Just upgraded it with pip, it works like a charm :)
Thanks 👍

[kmike]

sorry for the troubles!

[alejandroMA]

No worries 😁
