Generate thumbnail and standard image on request, and use http://github.com/mirumee/django-images for generating them. Also, remove the CreatePin page as pin creation is going to be done in JavaScript. Create UploadImage view for uploading images from computer.

class LoginRequiredMixin(object):

"""
|
|
A login required mixin for use with class based views. This Class is a light wrapper around the
|
|
`login_required` decorator and hence function parameters are just attributes defined on the class.
|
|
|
|
Due to parent class order traversal this mixin must be added as the left most
|
|
mixin of a view.
|
|
|
|
The mixin has exactly the same flow as `login_required` decorator:
|
|
|
|
If the user isn't logged in, redirect to settings.LOGIN_URL, passing the current
|
|
absolute path in the query string. Example: /accounts/login/?next=/polls/3/.
|
|
|
|
If the user is logged in, execute the view normally. The view code is free to
|
|
assume the user is logged in.
|
|
|
|
**Class Settings**
|
|
`redirect_field_name - defaults to "next"
|
|
`login_url` - the login url of your site
