Stack error with Hash.to_json for nested number values
Reported by Noel Rappin | July 18th, 2008 @ 10:51 AM | in 2.x
Here's the test
hash = {
"CHI" => {
:dislay_name => "chicago",
:latitude => 123.234
}
}
result = hash.to_json
And the result
Error:
test: Institution should output json. (InstitutionTest):
SystemStackError: stack level too deep
/Users/noel/Projects/botanic/plant_collections/vendor/rails/activerecord/lib/../../activesupport/lib/active_support/json/encoding.rb:29
Poking around, converting the number to a string did not trigger the problem, and using a flat hash rather than a nested hash also did not. I'm wondering if this is a odd side effect of the stack check to avoid circular references?

Creating a bug report
When creating a bug report, be sure to include as much relevant information as possible. Post the code sample that causes the problem. Preferably, alter the unit tests and show through either changed or added tests how the expected behavior is not occuring.
Security vulnerabilities should be reported via an email to security@rubyonrails.org, do not use trac for reporting security vulnerabilities. All content in trac is publicly available as soon as it is posted.
Then don't get your hopes up. Unless you have a "Code Red, Mission Critical, The World is Coming to an End" kinda bug, you're creating this ticket in the hope that others with the same problem will be able to collaborate with you on solving it. Do not expect that the ticket automatically will see any activity or that others will jump to fix it. Creating a ticket like this is mostly to help yourself start on the path of fixing the problem and for others to sign on to with a "I'm having this problem too".
