Default rendered error file and hash to nice string how to

rubyonrails-talk

Hi,

When rails raises an exception which file (view?) gets rendered and outputs in the browser the backtrace, request, parameters, etc.

I'm asking that because I'd like to know if Rails provides an easy way to convert a hash to a readable string, eg:

"{:key => 'value'}" instead of yukky #to_s which gives "keyvalue".

Thanks

Maybe you can override to_s?

Are you looking for something like p or inspect ?

Thanks

Best,

Damn' it! I completely forgot about Hash#inspect! Thanks Marnen :slight_smile:

I think I'm experiencing an issue with Hash#inspect: if one of the values holds a file, it seems Ruby keeps it as a file, so I'll let you guess what may happen if the file is a bit big when I just expect a little string to represent that file...

So check for File values. What's the problem?
