Django - Where to write code for easy-thumnails custom THUMBNAIL_NAMER?

Question

I am working on a Django project using the wonderful easy-thumbnails plugin to generate thumbnails for images. I don't like how the thumbnails have the format of:

source.jpg.100x100_q80_crop_upscale.jpg

If my image is named source.jpg, I'd much rather have something like:

source_thumb.jpg.

Upon reading the plugin's docs (http://easy-thumbnails.readthedocs.org/en/latest/ref/settings/), I have discovered that there is a setting where I can set a custom THUMBNAIL_NAMER, which is essentially a function that returns the desired thumbnail string.

My Question:

Where is the proper place to define this function in my project? I want to maintain a logical and clean project structure, and am unsure where to place this function.

Thank you so much for any help :)

Answer 1

THUMBNAIL_NAMER is a setting, and the default is

THUMBNAIL_NAMER = 'easy_thumbnails.namers.default'

which means, in the easy_thumbnails packages, a method named default in namers.py

Source code: https://github.com/SmileyChris/easy-thumbnails/blob/master/easy_thumbnails/namers.py#L7

So, if you wish to override it, in your settings.py

THUMBNAIL_HELPER = '<myapp>.namers.default'

and then have the overriden definition of this method in the package myapp (any app that is in INSTALLED_APPS that would make most sense), in namers.py (well, it could be anything - just an example)

Since it is the thumbnail, if it is thumbnail associated with user's avatar, I would put it in the userprofile app.
