renderWith() not doing it's job

[kristof polleunis]

I have an ajax call that updates or sets a value and this ajax script works fine.  I can see the data being updated or added in the database.

Now the function it is calling (index) seems to do the update and insertion of the data.  To provide feedback to the callback function it's also supposed to render the some output as json

 some checks
...

userprogram.save();
<!--- Prepare the message for the user --->
response = {};
response["message"] = "Saved";
response["programid"] = "#userprogram.programid#";
<!--- Respond to all requests with `renderWith()` --->
renderWith(response);

It doesn't seem to output any json at all but just loads the index.cfm in the views folder which is then send to the javascript.  I used jquery for the ajax and have set provides(html, json) in the init part.

I can't figure out what is wrong here, no error messages at all and it was something I had working some time ago.

Hi Kristof,

Can you show us your ajax code.

THanks

You may want to consider using renderText() instead of renderWith():

renderText(SerializeJson(response));

I think renderWith() is going to cause it to expect an index.json.cfm because you're not really giving it supported construct like a query or array of model objects. I could be wrong on this though, so someone correct me if I'm wrong.

+1 to Chris Peters suggestion.

Yannick, the ajax code is working fine

[kristof polleunis]

Chris, Samson,

With renderText it's working.

I just thought that in the docs it said renderWith() would automatically transform the data

Automatic Generation of XML and JSON Formats
If the requested format is xml or json, the renderWith() function will automatically transform the data that you provide it. If you're fine with what the function produces, then you're done!

[Chris Peters]

Guess it only supports certain data constructs. Seems like it should do its own SerializeJson() if it's not a "supported" construct.

Last thing I'll ask is what if you change it to answer to "js" instead of "json"?

Are you using ?format=json in the ajax request url?
