Large files eat memory

[matthewlein]

After uploading some very large (700mb) videos, I noticed this field was eating 20-30% of my available RAM on show and edit pages. It was also very slow. I edited a local version that removed rendering of the show template, and the RAM use went away.

If I had to guess, I'd say that the show field getting the entire field object is whats causing it.

<%= render 'fields/carrierwave/show', field: field %>

I'd suggest maybe an option to render that field, or look into just passing the filepath if thats all you need. I might look at those options myself but for now my workaround is just referencing a model method that just does field&.url instead, and the form template without the show rendering.

Hi @matthewlein!

Thanks for flagging that. I think your analysis is right. Would you be able to submit a PR that adds an option to conditionally render the show partial?
