dojoType="dijit.form.Form" >{% csrf_token %}

</form>

In views.py i added

def login(request):
return render_to_response('login.html')

In urls.py i added

(r'^login/', include('macrohms.views.login')),

The Error when i press login button:
ImportError at /login/

(r'^login/', include('macrohms.views.login')), is incorrect.

the include() function, pertaining to urls.py is for including other
URL confs (so you can have sub-sections of your site contain their own
urls.py). You'll want to replace that line with:

url(r'^login/$', 'macrohms.views.login')),

Note, I changed two additional things - I changed your tuple to a
url() function call instead, and I added a $ at the end of the URL
pattern (denotes the end of a string in regex). The url() function is
the "cool" way to define URLs.

Thanks a lotttt :)

but there is a new error

The Error:

Forbidden (403)

CSRF verification failed. Request aborted.
Help

Reason given for failure:

CSRF token missing or incorrect.


In general, this can occur when there is a genuine Cross Site Request
Forgery, or when Django's CSRF
mechanism<http://docs.djangoproject.com/en/dev/ref/contrib/csrf/#ref-contrib-csrf>has
not been used correctly. For POST forms, you need to ensure:

- The view function uses
RequestContext<http://docs.djangoproject.com/en/dev/ref/templates/api/#subclassing-context-requestcontext>for
the template, instead of
Context.
- In the template, there is a {% csrf_token %} template tag inside each
POST form that targets an internal URL.
- If you are not using CsrfViewMiddleware, then you must use
csrf_protecton any views that use the
csrf_token template tag, as well as those that accept the POST data.

You're seeing the help section of this page because you have DEBUG = True in
your Django settings file. Change that to False, and only the initial error
message will be displayed.

You can customize this page using the CSRF_FAILURE_VIEW setting.

User logs into your site (SaadsDjangoSite.com). User goes to
CriminalCSRFSite.com while logged into yours. They put a script tag in
their page that has a post-back to ttp://saadsdjangosite.com/delete-everything-and-kill-kittens/.
This causes the user's logged in browser to make a request to your
site, and delete everything and kill kittens, all without the user
knowing what happened.

Follow those instructions. Make sure you put {% csrf_token %} right
after your open <form> tag.

Thanks for your help :) Yup, I already did that, added {% csrf_token %} just
after <form> tag..still the same error comes up :(
The error page that comes up comes with a list of three possible
sources of error.

Have you ruled out those?
