Hi guys,

I have a simple blog project. When I go to my domain www.nomadpad.io I get "Server Error 500"

From the error log below, it appears to be something to do with my editedimage field, which looks like this in my models.py :

editedimage = ProcessedImageField(upload_to="images", blank=True, null=True,
                            processors = [Transpose()],
                            format="JPEG")

This all works fine in my development environment. I can still access my live django-admin page, and when I try to upload an image, when I save the post, it returns again the Server Error 500.

Are you sure that you're using all the same libraries with the same versions as you're using locally?

Hi Glenn,

Locally I did pip freeze > requirement.txt,

and then in my dev environment I just did pip install -r requirement.txt so it should all be the same right?

Thanks

deleted edit here. gitignore tidied up, and no longer getting commit issues, but still server error 500

Going to your domain, I don't see a server error 500?

Hi Conrad, I realised the problem was with my imagekit package. I removed the below field from my models, and now I can see my domain, but without the css processing:

editedimage = ProcessedImageField(upload_to="images", null=True, processors = [Transpose()], format="JPEG")

But i really would like this, because I can't get ckeditor to keep my pictures rotated correctly!

Thanks

Do you mean that this line:

editedimage = ProcessedImageField(upload_to="images", null=True, processors = [Transpose()], format="JPEG")

is erroring? If so, what is the error message?

Hi Conrad, I figured out that it was because the images being saved to that field in development weren't being transferred across to production. So once I re-uploaded them in production I don't get the error any more.

Only thing left now is that my CSS isn't working! I've ran collectstatic, and still nothing, no images either.

Your static file mappings are wrong. Re-read this.
