I know I figured this out sometime, but can't remember now. How does one make a variable that is automatically accessible to all views?

I mean like the current_user variable provided by Flask-Admin: it automatically calculates current_user and makes it available to the view for each request, without having to manually define it each time.

Basically, make it so that instead of...

@app.route('/example')
def example():
    my_var = something()

@app.route('/example/2')
def second_example():
    my_var = something()

...it automatically calculates my_var without having to manually define it in each view.

Okay, I hope that was clear. And thanks in advance!
