BigDecimals are wrapped in quotation marks about jbuilder HOT 8 CLOSED

I guess to_s is called on BigDecmials so instead of

json.(variant, :price, id)

I can use...

json.price variant.price.to_f
json.id    variant.id

from jbuilder.

I guess this should be fixed internally. Will give it a try. Imho the result should be a float-esque representation of the BigDecimal.

>> number = BigDecimal.new('1.23')
=> #<BigDecimal:7fb0e0b506d8,'0.123E1',18(18)>
>> number.to_json
=> "\"0.123E1\""
>> MultiJson.dump(number)
=> "\"0.123E1\""

Blast from the past, as I just ran into this again. Looks like it was fixed in a fork but never merged into master? You should definitely not have to explicitly cast a decimal to a float.

JSON spec does not introduce any limits for floats or integers, but JavaScript engines that are used to parse this do. For instance JavaScript floats are represented with 64 bits, and integers only have 32 iirc.

So, Ruby's Bignum can theoretically be properly encoded into JSON, but none of the existing JavaScript engines would be able to parse it correctly. And Ruby's JSON and ActiveSupport tend to make it JavaScript compatible in the first place.

If you're absolutely sure your BigNums aren't gonna overflow, cast them to integers or floats before passing to Jbuilder.
