In Chapter 6, Securing Your App, we created an interface to allow users to create and edit blog posts without having to use the CLI. This was adequate to demonstrate the security measures presented in the chapter, but there is still no way for posts to be deleted, or to assign tags to posts, using the interface. We also do not have a way to delete or edit comments that is hidden from regular users. What our app needs is a fully featured administrator interface, in the same vein as the WordPress interface. This is such a common requirement for apps that a Flask extension, called Flask Admin, was produced to help developers create administrator interfaces easily. Once more, we can find Flask Admin on the list of dependencies in requirements.txt.
Since we are going to create a full administrator interface, with forms, views and templates, Flask Admin is a good candidate...
