Question

anyone seen this array error before?
I have a helper method that returns an array. In development mode on my laptop it returns the array in an expected format:

var fire = 
[[1349083353000, 8.860000000000582], [1349085153000, 19.779999999999745],
[1349086953000, 20.289999999999964], [1349088753000, 29.850000000000364], 
[1349090553000, 3.7999999999992724]];

BUT same code in production returns a strange array format:

var fire = 135175422800015.5135175602800020.0135175782800018.99135175962800012.33135176142800019.13135176322800029.55135176502800020.13135176682800077.34

I have tried checking the output in rails console on either machine and the production output the same weird array format. I have created a new array from within rails console on production and it works as expected to output the correct format of array.

Anyone seen this bit of weirdness?

Rails version:3.2.8
Ruby Version:1.9.3p-125

You’re probably developing on Ruby 1.9 and deploying on Ruby 1.8. The default behaviors for treating arrays are different.

In Ruby 1.8 array.to_s is equivalent to array.join('').

In Ruby 1.9 array.to_s is equivalent to array.inspect.

If you want the proper behavior on both, and you’re using JavaScript, you might want to render it as JSON using array.to_json instead.
