Updates Outcomes::LearningOutcomeGroupChildren by adding cache
at the queries for getting the total subgroups and outcomes.
closes OUT-4148
flag=improved_outcomes_management
Test plan:
- Create nested learning outcome groups
- For each nested learning outcome group create learning outcomes
> With FF improved_outcomes_management: OFF
- On Rails console: calls to Outcomes::LearningOutcomeGroupChildren
methods should return a default value
- On web: when generating actions over ContentTag, LearningOutcome
and LearningOutcomeGroup it should not lead to clear any cache
> With FF improved_outcomes_management: ON
- On Rails console: call Outcomes::LearningOutcomeGroupChildren
methods for getting total subgroups and outcomes, queries to the
DB should be made (it will need the root context)
- Call again the same methods, it should return the values from
cache
- Create a new instance of the class and call the same methods,
it should return the values from cache
- Clear the cache with `Rails.cache.clear`
- On web (or through GraphiQL) get the total subgroups and total
outcomes multiple times; it should cache the data and should not
run additional queries
- On web: clear the cache by executing the following actions:
- Add a Learning Outcome Group
- Adopt a Learning Outcome Group
- Copy a Learning Outcome Group from global
- Remove a Learning Outcome Group
- Add an Outcome
- Remove an Outcome
- Get the total subgroups and total outcomes, it should run new
queries
- Run the same tests for global context, it should generate and
clear the cache in the same way
