Rebuilding old (2010) django project in 2012

Question

I am trying to make an old Django project run again.

Update #1: I removed the arguments extra_thumbnails and size so the server is running. But now I don't have proper thumbnails of my pictures...

    image = ImageWithThumbnailsField(
    upload_to='images',
    thumbnail={'size': (120, 120)},
    extra_thumbnails={
        'icon': {'size': (32, 32), 'options': ['crop', 'upscale']},
        'large': {'size': (640, 640)},
    }

now looks only:

    image = ImageField(
    upload_to='images')

After seemingly having solved issues with old sorl.thumbnail versions and deprecated expressions I now get this error when running

python manage.py runserver

I also tried to copy & paste my old files into a new Django project and get the exactly same error. Maybe someone here has a clue where the problem lies?

    super(FileField, self).__init__(verbose_name, name, **kwargs)
TypeError: __init__() got an unexpected keyword argument 'extra_thumbnails'

I need to re-build the project just for visual documentation locally... so also any hints on how to quickly re-run outdated django-projects are very welcome!!

Thanks a lot!

Answer 1

A guess into the dark: Remove the keyword argument extra_thumbnails in the field definition FileField in the file cityofwindows/models.py

If this does not solve the problem, please post the cityofwindows/models.py file.

You probably uses another version of Django. Install Django 1.0 (https://www.djangoproject.com/download/1.0.4/tarball/) is the easiest why, but not the best. You'd better update your project with the standards of the version 1.3 (see 1.4)
