I'm attempting to save the params from PayPal's IPN so they can be accessed later and used for cross reference.
Simple little bit of code that saves it in the paypal_log column:
@order.paypal_log = params.to_json
Worked fine, pushed to production and still was working fine. Investigating the logs for another issue, I came across the following line:
Completed 500 Internal Server
JSON::GeneratorError (source sequence is illegal/malformed utf-8):
The line it points to is the above params.to_json
After looking around I discovered force_encoding("ISO-8859-1").encode("UTF-8")
(source)
I changed the line to params.force_encoding("ISO-8859-1").encode("UTF-8").to_json and ran my tests with a error of:
undefined method `force_encoding' for #<ActionController::Parameters:0x000000073357f0>
This makes me thing that for some reason, you can't parse the whole params variable, only a hash. Any possible solution for forcing encoding for all params?
Can iterate over each param and force the encoding.
params.each { |k, v| params[k] = v.force_encoding('ISO-8859-1').encode('UTF-8') }
