photo_dl_link error 'FileSystemStorage' object has no attribute 'url_monkeypatched'

Hi all,

When I upload images for instructor , I set course Preview only mode . And I access localhost:8000/courses/coursestest1/preview/  I get error :

AttributeError at /courses/coursestest1/preview/

'FileSystemStorage' object has no attribute 'url_monkeypatched'

.........

In template C:\Program Files (x86)\VertrigoServ\www\class2go\main\templates\previews\default.html, error at line 21

Hi,

There are two things going on here. First, there's a bug in the photo link method on the Instructor model. Second, you may not want to be using the Instructor model either.

I pushed a branch that probably fixes the Instructor object. It's called 'jrbl-default_preview_less_sketchy'. Please check the branch out and try it and see if the error goes away. Once you commit whatever work you have in progress on your Class2Go checkout, you can check the branch out on Linux (and I believe also on Cygwin, but I'm less sure) with:

git checkout master && git fetch -p origin && git pull origin master && git checkout jrbl-default_preview_less_sketchy

When you're done checking you can use 'git checkout' to return to whatever branch you were working on before.

But! I should also say that I haven't been able to find evidence that people are relying on the default preview page much in practice. If you look in main/courses/preview/views.py, you'll notice that the default.html only gets used if there's not a course-specific preview page available, with a name like (for example) db--winter2013.html.  You can see a number of examples of these in main/templates/previews.

So you may simply want to copy one of the preview pages that you like to be named like the course handle for the course you're working with, and then edit that page to be the way you want.

David Glance, can you look at Joe's proposed change (https://github.com/Stanford-Online/class2go/pull/2488) and see what you think?  This was originally your code.
