AttributeError: 'unicode' object has no attribute 'build_url'

[dinhn4]

I upgraded from version 1.4.0 to 1.7.0. Using Django 1.6.2

I have a field in my models.py icon = CloudinaryField('image', max_length=256, null=True, blank=True)

I used to use it like this to get the image url icon.build_url()

But after upgrade I get this error AttributeError: 'unicode' object has no attribute 'build_url'

Debugged it and discovered that my icon object changes from a CloudinaryResource object with 1.4.0, but now it is treated like a unicode object with 1.7.0.

• Change happened somewhere between 1.4.0 and 1.5.0

Hi @dinhn4, we do not officially support Django 1.6 with our latest SDK, so if you must use Django 1.6, it might be better to use the older SDK version which worked for you. With that said, we might be able to find a workaround for this specific issue. Can you please send us the following information:

1. The Python version you are using.
2. Full stack trace of your error.
3. If possible, the relevant snippet of code that produced the error (so we have some context).

Thanks

Hi @roeeba , Thanks for the response.

    return icon.build_url()

facility_edit.html

{% load facility_extras %}
 src="{%if facility.folder_icon_temp %}{{ facility.folder_icon_temp }}{%else%}{%if community_folder_app.icon %}{% enterprise_portal_icon community_folder_app.icon %}{%else%}{% static 'img/icon_default.png' %}{%endif%}{%endif%}"

community_folder_app is an object with a field icon = CloudinaryField('image', max_length=256, null=True, blank=True)

This is only one example. All other calls to build_url() on a CloudinaryField object breaks for me. Thanks

Hi @dinhn4, We've investigated your configuration. There are numerous issues when using our latest SDK with Django 1.6.2. We will try to address them in one of our next SDK releases, but we can't currently commit on that since 1.6.2 is old and unsupported by Django since 2015. Right now, if you can't upgrade Django, the best option is to stay with the older SDK version that worked for you.
