How to give key_prefix, variable values while caching in Flask-Cache

Question

We can cache any view/non-view function as

@cache.cached(timeout=50, key_prefix='all_comments')

Can we give key_prefix some variable values. Let say, I'm caching a function as

@cache.cached(timeout=50, key_prefix=value)
def get_all_comments(value):

Can we give key_prefix as the same arguments as we are getting in function. If not argument, then atleast some other variable by any proper way.

Answer 1

In the docs it says

New in version 0.3.4: Can optionally be a callable which takes no arguments but returns a string that will be used as the cache_key.
