Will Racket's pleasant surprises never end? :) This is great news! I've had a blast coding web applications in Racket over the last 15 months. I now understand "The Lisp Curse" a bit more :)
http://winestockwebdesign.com/Essays/Lisp_Curse.html In other words, developing web apps with what is already provided by Racket, and a few packages, has been easy & enjoyable enough that it's delayed my work on a web framework. That's probably been for the best because now I have a few real world examples from which I can begin to extract the code that belongs in a general framework. I'll be resuming that work this month. I watched the "how to create a blog in 15 minutes w/ Rails" video 14 years ago, and it had a huge impact on my work. There are still some very nice things to steal from Rails, and a whole lot of things to leave :) If you're interested in web development, and you haven't seen this video, I highly recommend it. There are some annoyances for sure, but be patient. https://www.youtube.com/watch?v=Gzj723LkRJY&feature=youtu.be On Thursday, February 13, 2020 at 11:02:33 AM UTC-5, bogdan wrote: > > The version of the web-server that will be included with Racket 7.6 > changes the way file uploads are handled so that they get offloaded to > disk after a certain threshold (similar to how that nginx module you > linked to works). > > You can check out the pre-release docs for details: > > * > https://pre-release.racket-lang.org/doc/web-server/http.html?q=binding%3Afile#%28def._%28%28lib._web-server%2Fhttp%2Frequest-structs..rkt%29._make-binding~3afile%2Fport%29%29 > > * > https://pre-release.racket-lang.org/doc/web-server-internal/dispatch-server-unit.html#%28part._safety-limits%29 > > > To get these changes ahead of the release, you should be able to install > an updated version of `web-server-lib' from the package server or from > git. > > Hope that helps! > > - Bogdan > > Brian Adkins writes: > > > I'm posting a file to my web app using the following form: > > > > <form accept-charset="UTF-8" action="@(url-for 'upload-contacts > > (organization-id org-obj))" > > method="post" *enctype="multipart/form-data"* > > class="file-upload-form"> > > ... > > </form> > > > > I use a simple function to create a hashtable of attributes: > > > > (define (form-values req) > > (for/hash ([ b (in-list (request-bindings/raw req)) ]) > > (cond [ (binding:form? b) (values > > (bytes->string/utf-8 (binding-id b) > #\space) > > (bytes->string/utf-8 (binding:form-value > b) > > #\space)) ] > > [ (binding:file? b) (values > > (bytes->string/utf-8 (binding-id b) > #\space) > > (binding:file-content b)) ]))) > > > > It appears that the entire file contents are in the binding by the time > the > > request is available to me.
