Is there a way to recalculate just one memoized attribute?
Closed this issue · 7 comments
I know that the prevailing memoized_attribute(true) approach is somewhat flaky but is there a way to recalculate a given memoized property without expiring the entire cache so to speak?
As well I apologize if my knowledge of memery is somewhat limited but does it memoize functions that accept arguments?
Skipping memoization is covered in the Readme here: https://github.com/tycooon/memery#difference-with-other-gems.
In your case you can either provide an empty block or create an extra unmemoized method and use it in the memoized one.
Functions with arguments are supported, that's covered in the Readme as well :)
Yes, that's well understood, but apart from clearing the entire cache, there's no way to recalculate (and rememoize) a memoized value, is there?
The readme could be more explicit about the memoization of functions with arguments, it's only a passing reference which is why I'm asking to be certain

Right now there is not. I guess we could add an optional argument to clear_memery_cache! with the method names.
It's very kind of you to take this into consideration --
It's not particularly pressing in my particular case -- I'm using memoization to cache a rather expensive API request and need to re-query after performing an update operation.. expiring the whole cache does fit into my use case but I was more curious about best practices.
