after save session hook?

From:: Bharadwaj Parthasarathy

I am building an app for a cookie less environment and I am using server 
side sessions with URL rewriting for passing session_id.
I am using an server side session store(Flask KVSession), which uses a 
dictionary store for sessions.
I am trying to pass session id to the template.  

On the first request, I am storing objects on the session. However, I am 
not able to pass the session.id to the template.
This is because the save_session call happens after most hooks. I am not 
able to use @app.context_processor nor @app.after_request
The @app.context_processor is called before the save_session.
The @app.after_request is called after the save_session, but the response 
seems to have been already built.
Is there a way to inject data to the context after save_session and before
make_response?

Thanks

Hi,

Try saving the session to a dummy response to force the ID to be 
generated. Saving the same session twice will probably keep the same ID, 
but I don’t know the details of KVSession.
