sending json data from rails form

Question

I have a rails form, which has some fields.

Now i want to send values of these fields, converted to json to some url

I can traverse through each element of form, convert it into json(using javascript) prepare a json string and send a request to the server.[client side conversion]

Other approach can be, posting the form normally to some controller action. then reading the data on the rails controller. parsing it to json and sending to desired url[server side conversion]

But i dont think these are good approaches.

what can be better way to do this?

Answer 1

Why do you want to convert before sending to the server? You can easily generate JSON in Rails on the server side using the submitted POST data.
