Question

I have a Grails app running on 1.3.7 with the json-rest-api plugin version 1.0.8 installed. I’m trying to post data from the command line using curl in order to create a new instance of a domain class, but cannot seem to figure out the correct way to format the JSON so that the parser is satisfied. I can’t find any documentation either that would conclusively describe how the data is supposed to be formatted.

The domain class is defined like this:

package foo

class Foo {
  static expose = 'foo'

  String name

  static constraints = {
    name(inList: ['xyzzy', 'quux'])
  }
}

Given the above, this doesn’t work:

$ curl -X POST --header "Content-Type: application/json" --data-urlencode '{"name":"xyzzy"}' http://myapp/api/foo

The app returns a 500 error code and the content of the reply is

{"success":false,"message":"Property [name] of class [class foo.Foo] cannot be null"}

What kind of data does the API expect me to send?

Answer 1

Try the following format:

{ data: { name: "Blabla" } }
