Django Admin Sorl-Thumbnail Link

Question

I am having trouble adding an html A tag around the img tag. When I add the A Tag with the variable, it stops showing the image in the Django Admin, but without the variable in the A tag it shows the image. I can't seem to figure this out, and possibility it may not be supported by sorl-thumbnail?

*UPDATE Trying to pass two variables now with different thumbnail sizes, but it's not doing anything. I'm new working with definitions in Django Admin.

def screenshot_img(self, obj):
    if obj.screenshot:

            s = get_thumbnail(obj.screenshot,"x200",crop='center', quality=99)
            b = get_thumbnail(obj.screeshot,"x500",crop='center', quality=99)                

            return u'<a href="/im_troubleticket/media/%b"><img src="/im_troubleticket/media/%s"></a>' % (s, b)
    else:
            return u'No image'


screenshot_img.short_description = 'Picture'
screenshot_img.allow_tags = True

Answer 1

You are using the variable twice in the string, so you need to supply it twice:

return u'<a href="/im_troubleticket/media/%s"><img src="/im_troubleticket/media/%s"></a>' % (s, s)

EDIT: You have two new bugs in your code: First, you misspelled obj.screenshot. Second, the placeholders in your string indicate the type of data, not the name of the variable. See Python String Formatting. If you use descriptive variable names you are less likely to confuse the s in %s with the name of the variable.

thumb_small = get_thumbnail(obj.screenshot,"x200",crop='center', quality=99)
thumb_large = get_thumbnail(obj.screenshot,"x500",crop='center', quality=99)                

return u'<a href="/im_troubleticket/media/%s"><img src="/im_troubleticket/media/%s"></a>' % (thumb_small, thumb_large)
