Rails/ruby seems to be interpreting the content in "render :file" request
Got a weird situation:
I send a pdf to the user using this line in my controller:
format.pdf { render :file => pdf_file_path }
This has been working fine. But, on one specific file (meaning specific file
content) I get this error, which makes it look like Ruby via Rails is trying
to interpret the content of the file as code. Because other files are
downloading fine, and from the error message I conclude that Ruby is in fact
trying to interpret the file content:
exception.message: \"compile error\\n\\\n
/media/lqidatastore/production/temp/297_standard_view.pdf:736: Invalid char

/media/lqidatastore/production/temp/297_standard_view.pdf:736: Invalid char

The actual error is longer but you get the point. There is no line 736 in my
controller, but there is in the pdf file:
Line 736:

So the million dollar question is what could make Rails decide to interpret
the content of a file which we are asking for it to pass down to the user?
And better yet, is there a way I can tell Rails "hey, this is a file, lay
off"?

Does it have a conventional ruby stack trace dump? If so can you post it? What do you see in the rails log?
