sorry, jquery-in-place-editor is not that flexible. its a good start but using it with rails (i guess with other languages/frameworks to) is a pain.
you can't change the request type (its always POST). you cant dynamicly change the params (you can specify a string but only on initialisation NOT when you submitting the form)
i had to modify it a lot to do sth like:
$(".component_header span").each(function(){
var $that = $(this)
$that.editInPlace({
url: "/components/"+this.id.split("_")[1]+".js",
params: function () {
var value = $that.find('.inplace_field').val()
return {"component": { name: value }, authenticity_token: FORM_TOKEN }
},
type: "PUT"
});
})
i'am almost happy with that, but there are some other issues (error handling) i will work on that before i put my app to public.
unfortunatly the code is on google code, so couldn't fork it...
