Can I .send() something from a regular Pyramid view?

[thapar]

Is there any way to .send() something to the current user from a regular Pyramid view?

you have to know session id for current user to send messages to it. pyramid_sockjs does not now anything about user id. well, there is a way, but it is very unoptimal. poramid_sockjs maintain internal session key as (authenticated_userid(request), sid), so you can do something like:

   for key, session in session_manager.items():
        if key[0] == current_user_id:
            return session

but i strongly suggest to add custom mapping between user id and session.

I have the session id mapped to the username in a dictionary, username as the key. So if I'm in a regular pyramid view, not a sockjs request/session, how can I .send() to the session id? Or how can I get ahold of the sockjs session? On Jan 22, 2013 12:52 PM, "Nikolay Kim" notifications@github.com wrote:

session manage holds all active session objects. you can use request.get_sockjs_manager(name), name is a name of sockjs route, by default it is empty string

so code can look like this:

   def my_view(request):
       sm = request.get_sockjs_manager()
       cur_sid = {'you user mapping'[userid]}
       sm[cur_sid].send('message')

request.get_sockjs_manager() gives me {('Guest6752', u'8z5hjq25'): <newsite.views.chat.ChatSession object at 0x5093810>}, where 'Guest6752' is the user's authenticated username on the website. So three questions:

1) Is ('Guest6752', u'8z5hjq25') the expected key? 2) Also, why is cur_sid a set? 3) By using the userid/username, how does that allow me to differentiate which sockjs Session the request came from (so I don't have to sm[cur_sid].send('message') to all the user's active sessions)?

Mr. Nikolay?

[fafhrd91]

session manager uses (userid, sessionid) for key, this is additional security for non persistent transports, like polling or streaming. You can disable this behavior, use config.add_sockjs_route(...., per_user=False)

[thapar]

And for questions 2 and 3, my good sir?

[fafhrd91]

2) what is cur_sid i dont see this in pyramid_sockjs code 3) re-state the question, i dont understand

[thapar]

2) in your example above ( https://github.com/fafhrd91/pyramid_sockjs/issues/20#issuecomment-12559918 ) you wrote cur_sid = {'you user mapping'[userid]}, perhaps as a typo, otherwise it looks like you are creating a set.

3) if a user has multiple tabs open, how can I .send() to the tab that sent the request. Using your example above would retrieve the full list of sessions for a username, and I would have to .send() to all the sessions. Instead, I would like to .send() only to the tab that sent the original request. Again, I'm looking to use .send() from a regular Pyramid view.

[fafhrd91]

2) just example, you can put there anything

3)

    class CustomSession(Session):

        def on_message(self, msg):
              # do processing
              ...

              self.send('message')

[thapar]

3) that example does not use a regular Pyramid view, where request is used instead of Session. Your original example ( https://github.com/fafhrd91/pyramid_sockjs/issues/20#issuecomment-12559918 ) was for a regular Pyramid view.

you have to develop some method how to map pyramid request and sockjs session. pyramid_sockjs does not do this.

[thapar]

Can you suggest on where I can start sniffing to figure this out?

[fafhrd91]

thats depends on flow of your application. i dont see reasons for such mapping at all because pyramid view is invoked before sockjs session even beeing created.
