I think you need to combine models using the Relational Active Record . In the process of self learning I'm following, I hope I will shortly have an example to post here...
If you add getters for groupId and groupName to the Member model you can easily display the gridview for members and include their group data. It's not an extremely clean solution, but it's the easiest.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
