问题 I'm working through the rubyonrails.org 'blog tutorial', and get this error when I try to submit a 'post' : Routing Error --No route matches [POST] "/posts/new" I copied and pasted the code from the tutorial into my code.

阅读更多关于 Routing issues with multi-part forms on Heroku

问题 This is a very bizarre problem, and unfortunately I can't provide a ton of information since I don't even know where to begin diagnosing the problem. I'm hoping somebody hear magically knows what to do, and I'm happy to clarify as necessary. For some reason, anytime I submit a new multi-part form with a file attachment on Heroku using Chrome, I am sent upon submitting to the default "index" action--that is, the page I would be sent to if I had submitted a GET instead of a POST. I'm using

阅读更多关于 Rails 3.2 f.file_field causes routing error

问题 Tested on rails 3.2.12 and 3.2.11. In another rails 3.2.11 project I do not have this issue with f.file_field , but in current one I do and can't find a reason for this strange behaviour, so here is my question.
