Hello, I’m trying to make an endpoint that returns a generated PDF file. Any suggestions? I can’t figure out how to render a binary response. Alternatively I could save it to S3 and return an URL but I’m hoping it’s possible in memory.
Thanks!
Have you tried setting the response headers? I’d guess that Content-Type: application/pdf would do it.
Hi Nate, thanks for responding. I’m not familiar enough with the render function (in Jets or ActionView) to even get that far. I’ve tried
render pdf: pdf_contents
… with/without Content-Type, etc, but I just get “ActionView::MissingTemplate”, so clearly I’m not rendering the content correctly and it’s not setup with the right templates, etc. I’ve tried registering a handler for the pdf: symbol but didn’t get very far.
Yeah, I’ve tried that already. It looks promising but the Jets controller doesn’t have that method defined. The controller doesn’t subclass the Rails one, but somehow implements a bunch of the logic, I suspect as an include. The controller just throws:
NoMethodError: undefined method `send_data’
Maybe try render plain: or render text: and set the content type header manually.
Awesome, that worked!
response.headers[‘Content-Disposition’] = “attachment; filename=\”#{filename}\""
render plain: pdf_content, content_type: ‘application/pdf’
