I want to set access control for DataView.
For example, User 1 belong to Dep1, User 2 belong to Dep2.
User1 can read data about Dep1 and Dep2, and can write data about Dep1 only.
User2 can read data about Dep1 and Dep2, and can write data about Dep2 only.
User1 and User2 have own board user account.
When user logged in, change DataView access control dynamically for read/for write.
I think I need to create two DataViews, for read/for write.
