Hi Djangonauts,
I need your help
I am trying to test a view using PIL(Python Imaging Library). This is
the code:
from django.http import HttpResponse, HttpResponseRedirect
from django.template import Context, RequestContext
from django.template.loader import get_template
from django.http import HttpResponse, Http404
from django.contrib.auth.models import User
from django.shortcuts import render_to_response
from django.contrib.auth import logout
from example_app.forms import *
from PIL import Image
import random
INK = "red", "blue", "green", "yellow"
def main_page(request):
return render_to_response(
'main_page.html', RequestContext(request)
)
def user_page(request, username):
try:
user = User.objects.get(username=username)
except:
raise Http404('Requested user not found.')
bookmarks = user.bookmark_set.all()
variables = RequestContext(request, {
'username': username,
'bookmarks': bookmarks
})
return render_to_response('user_page.html', variables)
def logout_page(request):
logout(request)
return HttpResponseRedirect('/image/')
def register_page(request):
if request.method == 'POST':
form = RegistrationForm(request.POST)
if form.is_valid():
user = User.objects.create_user(
username=form.cleaned_data['username'],
password=form.cleaned_data['password1'],
email=form.cleaned_data['email']
)
return HttpResponseRedirect('/register/success/')
else:
form = RegistrationForm()
variables = RequestContext(request, {
'form': form
})
return render_to_response(
'registration/register.html', variables
)
def image_page(request):
""" create/load image here """
image = Image.new("RGB", (800, 600), random.choice(INK))
""" serialize to HTTP response """
response = HttpResponse(mimetype="image/png")
image.save(response, "PNG")
return response
I am having the following error:
Traceback:
File "/home/tsinga/webapps/django/lib/python2.5/django/core/handlers/
base.py" in get_response
86. response = callback(request, *callback_args,
**callback_kwargs)
File "/home/tsinga/webapps/django/django_example/example_app/views.py"
in image_page
57. image = Image.new("RGB", (800, 600), random.choice(INK))
Exception Type: NameError at /image/
Exception Value: global name 'Image' is not defined
Thanks
