Sagelets in WebWork

[John Travis]

I've been trying to wear out the single cell server with sagelets from
within WebWork problems. If interested, you can view what I have thus
far by browsing http://math.mc.edu/webwork2/sage_demos/ and logging
into the system as guest. I need to fix at least one answer checker
but you can get the idea.

A minor issue that I have found with the single-cell is that it will
no longer allow one to use "input_grid" as part of an interact input.
This is not mission critical but just passing the word along.

What's the issue you're having with the InputGrid (or
input_grid for compatibility with the sagenb syntax)
interact control? I just tried a basic example on
sagemath.org:5467, and it worked as expected.

Below doesn't work for me. Replacing input_grid with two
"input_box"es works fine in the single-cell.

var('x,y,t,z')
f(x,y)=sin(x)*cos(y)

@interact
def
myfun(location=input_grid(1,2,default=[0,0],width=2),angle=slider(0,1,label
= "Angle"),show_surface=("Show surface", True)):
print 'hi'

This appears to be a bug in our code for achieving compatibility with
the
notebook's interact syntax (interacts were rewritten for the
singlecell). I've
opened an issue here:

For right now, if you use nested lists for the default value it works
fine:

default = [[0,0,]]

By the way, Alex fixed this and I pushed his fix to sagemath.org:5467,
so your example should work now.

Thanks,

Thanks to all for your work on the single-cell.

Has anything been changed with respect to aleph.sagemath.org ? This
morning everything was working fine but this afternoon my WebWork
sagelet problems only produce a session number and an empty box. No
go via the WebWork problem in Safari, Chrome OS or Firefox in Win7.
Also, a HTML file that calls the single cell using javascript (as in
the WebWork problems) fails in a similar manner. On the other hand,
browsing directly to the web site works fine still.

Also, just noticed the Android app is not working either.

No, nothing changed. I used it about an hour ago and it was working
fine. However, I see that it isn't responding now.

I see some errors on the server. I'll restart it for now and take a
look at the errors when I have time. I've also opened an issue with the
tracebacks.

It should work now.

Thanks,

Jason
