My JSON backend can return a single object or an array of objects.

My Ajax callback is managing the callback response.

It works fine if the response contains more than 1 object but an error is returned if the answer only contains a single object...

How to get a generic solution (1 or multiple objects) ?

function(response) {
  var posts=[];
  response.post.forEach( function (item) {
    posts.addObject( App.Post.create(item) );
  });
  return posts;
}

Postgresql: assign default timezone during table creation

I have the following definition of employees table

CREATE TABLE employees
(
  id integer NOT NULL,
  name text,
  withouttz timestamp without time zone,
  withtz timestamp with time zone,
  CONSTRAINT primarykey_emp PRIMARY KEY (id)
)
WITH (
  OIDS=FALSE
);
ALTER TABLE employees
  OWNER TO chris;

I have inserted two records in the following way:

INSERT INTO employees(
            id, name, withouttz, withtz)
    VALUES (1, 'test', '2011-01-01 00:00:00', '2011-01-01 12:00:00+03');

INSERT INTO employees(
            id, name, withouttz, withtz)
    VALUES (2, 'test', '2011-01-01 00:00:00', '2011-01-01 12:00:00');

I have written simple java class for select * from employees which outputs the following:

col1: 1
col2: test
col3: 2011-01-01 00:00:00
col4: 2011-01-01 07:00:00-8:00

col1: 2
col2: test
col3: 2011-01-01 00:00:00
col4: 2011-01-01 12:00:00-8:00

Question: Is there a way to create a postgres table's timestamp with time zone so that it considers the timezone to be UTC instead of server's local timezone ?

Note: set timezone TO 'GMT'; is not a solution for me because it is works in only a specific session. Also, it would be great if the solution doesnot depend on Server's local timezone at all

Thanks in advance

您可以通过调用来确定对象是否为数组Array.isArray()。
