Ajax Callback with Response Code other than 200

Hi again,

thinking a bit more about my X-editable plans, I dug a bit deeper into
JQAjax. Unfortunately, this gives me more questions than answers ;-)

Say I have an ajax callback using jquery like this:

html anchor
id: 'mylink';
onClick: (html jQuery ajax callback: [self doSomething]);
with: 'Click here'.

This callback will always respond with an empty HTTP response with
status code 200, right?
There are other callback methods on JQAjax, like respond:, text: and so on.

Is there any documentation on these?

I am looking for a way to transport some value to a server-side callback
block and respond with one of these two options:

a) HTTP 200 and a JSON document with success information and probably an
error message
b) HTTP 200 if the callback processed without errors, or a different
HTTP code and some error text in the response's body if there is some
error during processing the callback

Has anybody done this? Any pointers to more details?

Thanks in advance and happy new year to all Seasiders!

Joachim

Re: Ajax Callback with Response Code other than 200

Well, just trying things a bit, this seems to work:

"===================="
    html div
        onClick: (html jQuery ajax
            callback: [ :val |
                val inspect.
                self requestContext respond: [ :response |
                    response
                        contentType: 'text/json' seasideMimeType;
                        nextPutAll: {'what arrived was'. val} asJson
                    ]
                ]
            value: (JSStream on: 'this.innerHTML')
        );
        with: 't2'.
"===================="

Cheers,
Bob

Re: Ajax Callback with Response Code other than 200

Indeed.

There is a bit of doc on this here: http://book.seaside.st/book/advanced/restful/request-response

Although it’s in the context of REST, the #respond: method can be invoked in any request context (hence “self requestContext respond: [:response | … ]) to take low-level control on what Seaside should respond.

And there are methods on WAResponse to set the status code.

Cheers and happy new year!

Re: Ajax Callback with Response Code other than 200

Hi Bob, Hi Johan,

your answers are eye-openers for me. Until you pointed me into the direction of accessing the response via self requestContext, I was under the false assumption that you cannot answer Ajax callbacks with return codes other than 200. This opens a whole new universe for me ;-)

Thanks a lot!

So far I've managed to integrate X-editable perfectly, but am still looking for a way to replace the edited text with the new input as it was re-formatted on the server in response to the .editable() call. But that is more a javascript/jQuery/X-editable problem than a seaside one. the editable() success function has no effect, and I guess I'll have to try if complete works any better...

I'll make another handful of attempts before I look at jeditable, which allows you to submit the in-place-editing result to a local function in which I could send an ajax call back and do what I need (I think).
