알아요. 하지만 iPad와 Hub를 사용하면 여기저기 뛰어다니며 GitHub를 둘러보는 것보다 훨씬 쉽게 질문할 수 있거든요. 하지만 이번에는 단순히 게을러서가 아니라(이번엔…), iPad의 메모리가 부족해서 OS가 DiscourseHub를 강제 종료하기 때문이에요.
하지만 물론, .rb 트릭에 대해 알려주는 것이 일반적으로 더 정보학적이고 유용한 방법인 건 맞아요.
처음에 @Thoka가 그게 플러그인이라고 했을 때 믿을 수 있었는데, 정말 이상한 이유로 그렇게 하지 못했어요.

이것은 테마 컴포넌트가 필요한가요, 아니면 없어도 작동하나요?

테마가 필요하지 않습니다. 테마 없이도 정상적으로 작동합니다. 또한 설정 옵션도 없습니다. 설치 후 모든 PDF 파일을 브라우저에서 바로 열람할 수 있습니다.

가장 먼저 말씀드릴 것은, 해당 컴포넌트가 S3와 함께 완벽하게 작동하며 인라인 미리보기도 정상적으로 표시된다는 점입니다.
우리 포럼의 한 회원은 인터넷 사용에 대해 특히 위험 회피적인 접근 방식을 취하고 있습니다. 그는 Firefox를 사용하면서 애플리케이션 동작 설정을 변경하여 PDF 파일을 브라우저에서 표시하지 않고 다운로드하도록 설정해 두었습니다.
그가 이전에 PDF가 업로드된 특정 주제를 열면, Firefox가 매번 파일을 자동으로 다운로드합니다. 그는 기술적으로 유능한 편이지만, 그의 실력이나 경험을 보증할 수는 없으며, 이미 다음을 시도해 보았습니다:
클라이언트 측에서 CSS를
iframe.pdf-preview { display: none!important; }로 오버라이드하면 '미리보기’는 숨겨지지만, Firefox는 여전히 블롭을 다운로드합니다.
명백한 해결책은 Firefox의 브라우저 설정을 변경하여 파일을 Firefox에서 미리보기하도록 하는 것입니다. 하지만 다른 사람들이 자신의 온라인 보안 프로파일을 어떻게 관리할지 지시하는 것은 제 자리가 아니므로, 적어도 다른 해결책을 찾지 않고서는 그렇게 하지 않겠습니다. 어떤 아이디어가 있을까요?

흥미로운 우회 방법이지만, 어쩌면 ‘아기를 목욕물과 함께 버리는’ 식의 과잉 조치일 수 있겠네요. 
실제로는 Reddit 스타일 테마를 선택할 수도 있습니다. 대부분의 사용자는 익숙한 환경을 유지하는 것을 선호하는 것 같습니다. 이 부분은 염두에 두겠습니다.

당신은 의도적으로 사이트를 망가뜨린 뒤 그걸로 불평하는 사용자를 상대하고 있습니다. 그가 인라인 PDF를 원하지 않는다면, PDF를 표시하지 않을 수 있는 옵션을 제공하는 것이 어떻게 ‘버리는 것’이 되나요?

그는 자신이 선택한 브라우저 설정 때문에 PDF가 반복적으로 다운로드되는 것에 대해 불만을 제기하고 있습니다. '모든 사람을 항상 만족시킬 수는 없다’는 점을 감안할 때, 그는 이 문제를 감수해야 합니다.
그가 하는 어떤 행동도 다른 사용자에게 사이트가 깨지는 문제를 일으키지 않습니다. 만약 그가 자신에게만 작동하는 방법을 찾게 된다면, 저는 그것을 합법적인 해킹이라고 부를 것입니다.

안녕하세요
이것이 제 PDF 미리보기입니다
이것은 콘솔 오류입니다
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://cdn.my_site.com/original/1X/0d281938d3ff2377541704cab6ba1c4408420733.pdf. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 200.
여기서 문제는 이미지는 100% 정상 작동한다는 점입니다.

미리보기가 깨진 이 PDF 링크입니다.
https://my_site.com/uploads/short-url/1So7iQsrmIZKLQ6UGI86B1cOqD9.pdf
저는 CloudFront를 CDN으로 사용하고 있습니다.
다음은 S3 설정입니다.
my site S3
[
{
"AllowedHeaders": [
"*"
],
"AllowedMethods": [
"GET"
],
"AllowedOrigins": [
"http://my_site.com",
"https://my-test-site.site", # my test site use the same bucket.
"https://cdn.my_site.com",
"https://URL.cloudfront.net"
],
"ExposeHeaders": [
"Access-Control-Allow-Origin"
]
}
]
여기서 제가 놓치고 있는 것이 있는 것 같습니다…

CORS origin 관리 설정을 확인해 보세요.

저도 cors origin에 cdn.my_site를 추가했습니다.
/admin/site_settings/category/all_results?filter=cors origin
혹시 다른 것을 말씀하신 건 아니죠!

제가 말씀드린 내용이 바로 그것입니다. 만약 이 방법으로 문제가 해결되지 않았다면, 더 깊이 파고들어야 합니다. 이 주제에 대한 논의가 있으니 검색해 보시고, 진행 상황 알려주세요. 그러면 첫 번째 게시물에 해결책을 업데이트할 수 있을 것입니다.

결국 고倒是 했지만, 거의 정신을 잃을 뻔했어요.
앱을 여러 번 "재빌드"했고, 결국 Ubuntu 자체를 재설치하기도 했어요. 정확히 뭐가 문제였는지는 모르겠어요. 그 과정에서 AWS S3로 업로드 에셋을 수정하기도 했어요.
그 후에도 같은 토픽에서 같은 PDF로 계속 시도해 봤지만 
해결책이 없었어요.
결국 포기했고, 나중에 다른 토픽에 PDF를 업로드하니 작동했어요.
