SUMMARY

This PR fixes a bug from #11234 where cache keys for dashboard bootstrap data are incorrectly deleted.

We noticed this when some dashboard failed to update cache when updating charts.

delete_memoized from Flask caching treats instance method and class method differently:

        Delete memoized is also smart about instance methods vs class methods.
        When passing a instancemethod, it will only clear the cache related
        to that instance of that object. (object uniqueness can be overridden
        by defining the __repr__ method, such as user id).
        When passing a classmethod, it will clear all caches related across
        all instances of that class.

TEST PLAN

  1. Create a dashboard and add a chart
  2. Change chart title in Dashboard edit mode
  3. Explore the chart, make updates and save
  4. Return to dashboard and refresh. In base, you may see the chart is not updated. After the fix, the chart should update.

I guess that works, too. Just thought this feature is still unstable so let's start with something small.

The original code only updates the hash version related to the function: https://github.com/sh4nks/flask-caching/blob/v1.9.0/flask_caching/__init__.py#L1051-L1052
