POST JSON data to simple rails application with curl

Question

I set up a simple new rails application with model entry, with attributes title and content using scaffolding.

now I am trying to use curl to

Answer 1

I ran a test and got the error MultiJson::DecodeError (743: unexpected token at '{'content':'I belong to AAA','title':'AAA'}'):

JSON requires double quotes for keys and strings, not single quotes. Try --data '{"content":"I belong to AAA","title":"AAA"}'

Answer 2

take a block of JSON

{\"a\":\"this_is_a\"}

and url encode it

%7B%22a%22%3A%22this_is_a%22

and then use curl to post it

curl -i --data "working_params=%7B%22a%22%3A%22this_is_a%22" http://url/accepts/json

Answer 3

To go along with what Jonathan said, the Post is now sending the data to the EntriesController. Now in your create action you have to get the data from the params hash. I am going to assume you are doing it the railsy way and so you would do something like this:

    curl -d 'entry[content]=I belong to AAA' -d entry[title]=AAA http://localhost:3000/entries'

In your controller

    Entry.create(params[:entry])

This says grab the "entry" data from the params hash (created by rails for you) and pass it as a parameter to Entry to initialize a new Object. "create" will do a "new" and "save" for you in one method call.
