How to stop Rails being 'helpful' with assets that don't have extension in Dev/Test

1

I have an image in my assets ‘image.png’

In dev and test, rails will happily give me a url for

image_url "image"

but the same code crashes in production unless it gets

image_url "image.png"

personally, I think it is profoundly unhelpful for dev to ‘hide’ something that will cause a crash even if all my tests pass. Is there a way I can disable this behaviour?

This one has caused me problems more than once. Would love to figure out how to disable this too.

I’ve been tracking this one down and the guilty one is not Rails, but sprockets. When given a file, it actually removes the extension you gave it, then passes it to a method called resolve_under_paths, which then finds the best match given all files it has available in the pipeline.

Frankly, I don’t even know how to change this method without breaking other things. :expressionless:
