Using the simple server API

[Stefan]

Hi all,

I surfed through the discussion board and through the documentation on
trying to figure out how to get the simple server API up and running.
I made sure to run 'import sage.server.simple.twist' in my sage
prompt. Is there a way to easily test Sage to see if the API is
functioning such as entering the address into the address bar:

http://localhost:8000/simple/login?username=myusername&password=mypassword

I get the dreaded "Internal Server Error" message.

Thanks!

Yes, you should be able to do that. (See the example at the top of the
file.)

What does the terminal window where you started the notebook server say?

Hi Robert,

Thanks for getting back to me. The error I'm getting is:

File "/sage/sage/local/lib/python2.6/site-packages/sagenb/simple/
twist.py", line 207, in render
U = notebook_twist.notebook.user(username)
exceptions.AttributeError: 'NoneType' object has no attribute 'user'

This is probably somehow caused by the transition to the new notebook,
which is separated completely out from Sage, and which has undergone
many changes.

I have just upgraded from Sage 4.0.2 to Sage 4.2.1 and have
encountered the same error mentioned by Stefan.
Is there a way to fix the problem ?

Thanks in advance of any assistance!

William,

Do you know if anyone is actively maintaining this feature? I see
that it would be quite useful for various applications, so I'd like to
see it get resolved in one of the upcoming releases.

I'd be happy to chip away at the problem, but I'm relatively new to
the Sage community and might take me some time to get familiar with
the architecture.

Thanks!

We have a bug days workshop that starts tomorrow so we'll look then.
