many-to-many design question.


  • Subject: many-to-many design question.

Hello -

I have a pattern where I have a list of lists. These are called metrics and their possible values metricValues.

I want to assign a value for each metric to a project. This means that I have to dynamically show the metric list and then allow the user to select one value for each of the metric's list of values. I had originally created a many-to-many relationship to the metricsValue since that would be theoretically enough as I could always get the selected values metric. My problem occurs when the user selects a null value in the popup. Now I don't have a way to find its parent metric anymore.

How do others handle this list of list with a relationship design problem?

Thanks again,
James Cicenia
