Django Form Field Problems with Cloudinary's CloudinaryImage Class

Question

I've got a Django form that is displaying a ClearableFileInput for a CloudinaryImage (from Cloudinary). Things are working great, except when I display the form field, I get a mangled href in the anchor element:

Currently: <a href="&lt;bound method CloudinaryImage.url of &lt;cloudinary.CloudinaryImage object at 0x10b3f4ad0&gt;&gt;">&lt;cloudinary.CloudinaryImage object at 0x10b3f4ad0&gt;</a> <input type="checkbox" name="logo-clear" id="logo-clear_id" /> <label for="logo-clear_id">Clear</label><br />Change: <input id="id_logo" type="file" name="logo" class="span4" />

Here is the template code I am using:

<div class="fieldWrapper">
    <label for="id_logo"><h3>{{ form.logo.label }}:</h3></label>
    {{ form.logo|add_class:"span4" }}
    <p>{{ form.logo.help_text }}</p>
</div>

The add_class part come from django-widget-tweaks. I've taken the add_class part out with no change in the output.

Here is my form definition:

class OrganizationFormTheme(forms.ModelForm):
    pass

    class Meta:
        fields = ('logo',)
        model = Organization

It looks like Django is having problems with the CloudinaryImage's url function. I suspect it is looking for a simple property rather than a function.

Any suggestions on how to handle this? Should I subclass CloudinaryImage and rewrite the url function somehow?

Answer 1

Indeed there was a conflict between the url function and the url property. We've changed the function to be build_url instead of url.

In addition, you can specify transformation parameters as the url_options parameter when calling the constructor of CloudinaryImage. Then you can use the url property for getting the full Cloudinary URL.

The fix is available in the latest release of the Python library: http://pypi.python.org/pypi/cloudinary
