FW/1 seems to be oriented to returning complete web pages what if JSON data is needed? A typical layout looks like:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>User Manager</title>
<link rel="stylesheet" type="text/css" href="assets/css/styles.css" />
</head>
<body>
<h1>User Manager</h1>
<ul class="nav horizontal clear">
<li><a href="index.cfm">Home</a></li>
<li><a href="index.cfm?action=user.list" title="View the list of users">Users</a></li>
<li><a href="index.cfm?action=user.form" title="Fill out form to add new user">Add User</a></li>
<li><a href="index.cfm?reload=true" title="Resets framework cache">Reload</a></li>
</ul>
<br />
<div id="primary">
<cfoutput>#body#</cfoutput>
</div>
</div>
</body>
</html>
I have used code that overrides the onMissingView() method of Framework.cfc.
I wrap my response up in a variable named rc.json then use code similar to this in my Application.cfc.
function onMissingView( rc ){
if( structKeyExists( rc, 'json' ){
var response = getPageContext().getresponse()
response.setContentType( 'application/json' );
return serializeJSON( rc.json );
}
else{
//we need this to fire off valid onMissignView error.
raiseException( "FW1.viewNotFound", "Unable to find a view for '#request.action#' action.", " '#request.missingView#' does not exist.");
}
}
I use other logic to do a cfdump of rc.json when request is not an AJAX request. But this is scaled down to bare minimum.
As of FW/1 2.2, you can call:
variables.fw.renderData( "json", result );
in your controller and it will do what you want.
This will do it
<!--- Load all variables into response rather than just rc --->
<cfparam name="rc.response" default="#structNew()#">
<cfparam name="rc.response.status" default="OK">
<!--- Stop layouts from cascading --->
<cfset request.layout = false>
<cfsetting showDebugOutput="No">
<cfheader name="Content-Type" value="application/json" />
<cfoutput>#SerializeJSON(rc.response)#</cfoutput>
