Can you give me a simple example code to show how to use predicate
manually inside controller methods?

Hello there,
maybe this is not the prettiest version, but I had to get going, and I
solved a similar problem by not decorating the controller methods that
use AJAX with @require decorators. Instead I checked the predicated
manually inside the controller methods in question. Solved my problem
just fine, so if you just need it to work for now its good. You can
always keep a ticket open for the future to make it prettier.
Maybe somone else has a cleaner solution.
cheers,
Tom

I have a code like this in one of my controller code:
-----------
@expose('json')
@require(predicates.has_permission(u'something', msg=u'You do not have
permission!'))
def somejsonhandler(self, **kw):
somevalue = u'something'
someint = 123
return dict(somevalue=somevalue, someint=someint)
----------
This is called by an ajax code from the browser.
I can not catch the error, that code always returns status code 200.
I'm using jquery library for ajax.
The error handler code like this:
function AJAX_error(xhr, textStatus, errorThrown){
alert('Message from Server: ' + xhr.status + '\n:\n' + errorThrown +
'\n:\n' + textStatus);
};
this javascript is called and I see that status is 200 and it's actually
sending me the login page and it errors because ajax function was
waiting for a json response.
can you point me some hints to "how can I get 403 status code or
something other than 200 ?"
I'd like to update about this post:
When the user logged in, I can get 403 status code from javasript. But when
user is not logged in, controller tries to redirect to login page and I get
status code 200 and login page from ajax.
So, this redirect thing is only for 401 response. How can I disable redirect
for some controller methods that are called by ajax?
What I want to do is:
some controller methods are web pages so redirect to login page, and others
are called by javascript ajax functions so they should not redirect to login
page, they should return 401 or 403 responses so that I can catch the erron
on javascript side.
