I’m getting the same error right now when trying to use the gem formtastic version 0.2.4. My stackoverflow question can be found here http://stackoverflow.com/questions/8453521/ror-v2-3-error-actionviewtemplateerror-interning-empty-string I was wondering if you had any ideas on what the problem is since I have never seen an error called interning empty string.

I was getting this error yesterday afternoon. My context was a bit different, but I found that whenever I called the to_sym on an empty string, I got the “interning empty string” error.

WonderfuL! Was almost going mad over this one. In my case it is produced by a googlebot that appends the ?format= to soem of our apps urls. I still have no clue why it does it…

This is great info, thanks for the write up Fredrik, very well done. I have this error thrown occasionally in my app too. Had no idea why this was happening until I found your article. Cheers!

Tom, the format parameter’s empty value comes from http://localhost:3000/users/1?format= where the format parameter is present but doesn’t have a value.

If the format parameter would be missing from the url, however, the value of params[:format] would be nil.

And thanks for the spellcheck ;)

Thanks for this article! This one was confusing me… and I’m still not sure why “format” is set to empty string.

Quick correction though in the last code block you have this line:
params[:format] = nil if params[:format] and params[:foramt].empty?

And the “format” symbol is misspelled “foramt”.

Thanks again for the great article!
