I can't. I've tried compiling sagecell using the instructions posted online and have gotten countless errors. It appears that it is because I am running 10.9 not 10.6, but I cannot revert back to 10.6.

Ran sage: import sagenb.notebook.notebook_object as nb sage: nb.notebook(directory="mynotebook") And got the server running, I can log in on localhost. My problem is that for the past few weeks all I've been trying to do is set up a server *where data can be sent and evaluated and sent back,* my users will be sending requests from a separate site. I have been trying curl --data x http://localhost:8080/home/admin/0/ But keep getting 405 Method Not Allowed Method Not Allowed The method is not allowed for the requested URL. I really need to just send an http request and get it evaluated and get an httpresponse.

[sage-support] Re: Can't import sage into Python
Aha, that does make sense... And yes the Django import failed. My PATH has
Python version 3.4 on it which should have been a dead giveaway since Sage
runs Python 2.6? Or 2.7 I believe?
Would you recommend that I attempt to use kcrisman's answer, or try to
install Django in Sage's Python, OR should I use sage notebook?

[sage-support] Can't import sage into Python
I have a Django project with
views.py:
#!/usr/bin/env sage -python
from django.shortcuts import render
from django.http import HttpResponse
import sys
from django.http import HttpRequest
from django.template import RequestContext, loaders
sys.path.append('/Users/Jole/Desktop/django_proj/mysite/sage/src/bin')
sys.path.append('/Users/Jole/Desktop/django_proj/mysite/sage/')
from sage.all import *
def index(request):
querystring = request.GET.get('querystring')
return HttpResponse(querystring)
As you can see I am trying to import sage as a library into my Python
document so I can do some sage computations.
Unfortunately, when I fire up my Django server on localhost, I get: No
module named sage.all
As an error message. As you can see I have already tried appending to the
path. My Python Path includes sage and I can see this on my Django page,
however my "PATH" is
PATH
'/Library/Frameworks/Python.framework/Versions/3.4/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin'
According to the Django server output. I'm not sure if this could be the
problem. Any help would be *greatly appreciated.*

[sage-support] Help with understanding and setting up Sage Cell Server
Hi all, I've done some work in Java, HTML, CSS, JavaScript, ActionScript 3.0 and recently Python. I have a project I'm working on where I'd like to set up a very simple Sage server, to function as follows: The server will receive Sage or Maxima code, execute the code, and send back the result. Example, sending "integrate(1,x)" to the server would return "x". However, I have found myself getting a little lost in the process, I am not quite used to server-side scripting yet. The questions I'd like answered are: 1) Am I using the correct tool for the process, or is there an easier way to do this? I don't want a graphical interface on a website, I only want a server. 2) I've noticed on the Sage Cell Server demo online that typing Maxima code will result in every line being evaluated but Sage code only evaluates the last line. For example, integrate(1,x) integrate(2,x) In "Sage" code will return: 2 In Maxima will return : 1 2 Therefore, since I am more familiar with Maxima code I would like to set up the server to use Maxima code. Is this easily possible? 3) Is writing Python code required for this task? 4) How simple would the task be, of setting up a simple server like this? In Sage? In Maxima? Any resources would be appreciated. Thank you very much. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
