Patterns for Flask
==================
Certain features and interactions are common enough that you will find
them in most web applications. For example, many applications use a
relational database and user authentication. They will open a database
connection at the beginning of the request and get the information for
the logged in user. At the end of the request, the database connection
is closed.
These types of patterns may be a bit outside the scope of Flask itself,
but Flask makes it easy to implement them. Some common patterns are
collected in the following pages.
