Re: Attribute error, with a very basic banking app

Thank you so much Andromeda. I didn't know you could use class based views. I'll have a look at the documents. I don't know why I was trying to use them when I didn't need to.

The stacktrace is helpful, thanks!

The specific message with the AttributeError is helpful here: `AttributeError: 'module' object has no attribute 'DepositView'`

The line above it is `  File "/home/soupdragon/DJapps/banking/mybank/banking/urls.py", line 8, in <module>

    url(r'^deposit/$', views.DepositView.as_view(), name='deposit'),`

So I checked to see if your views.py contains anything named DepositView...and it does not. That's why the AttributeError is showing up.

The `DepositView.as_view()` syntax is suitable for class-based views, which means I expect to see something in your views.py to the effect of:

class DepositView(View):

  def post(self, request, *args, **kwargs):

    // the logic in your deposit() function actually belongs here

Have a look at the class-based views documentation to see what the different classes are, and what options they provide you.

Alternately, your urls.py could reference views.deposit (which does exist) instead of views.DepositView (which does not).

Hope this helps!

Could you share the full stack trace you get when trying to run the server ?
The attribute error should come with a ton of information like the
file and the line where the error occur.
