Hello

is there a Rails slack?

I have a Rails question, but nobody on IRC answers

could try the mailing list

maybe someone here knows this: http://stackoverflow.com/questions/32144651/handle-carrierwave-exception-and-add-error-on-one-to-many-relation

borkdude: you should actually catch this in your controller

@pxlpnk: how can I tell in which of the associated cards the exception happened?

the carrierwave gem hooks into your AR models

in general you should get away from the callbacks model and explicitly upload the files in its own module/class implementation

then you can catch which one of the cards fail but still complete the others for example

handling the callback madness of rails is not so nice

what we did is we have an explicit uploader class that handles this kinds of things, and we call .store! on the individual files

that sounds good

there is probably some railsy way of doing this but that leads mostly to a massive headache.

I am also removing most of the callbacks in our apps as they just suck

I guess that is what I like about clojure: everything is mostly transparent and explicit

(we had ~1500 registered callbacks in our app)
